In the reactor PIK design a burnable absorber is not used and the cycle duration is limited by the rods weight. Designed cycle time is two weeks and seams to be not enough for the 100 MW power research reactor equipped by many neutron beams and experimental facilities. Relatively frequent reloading reduces the reactor time on full power and in this way increases the maintenance expenses. In the reactor core fuel elements well mastered by practice are used and its modification was not approved. We try to find the possibilities of installation in the core separate burnable elements to avoid poison of the fuel. It is possible to replace a part of the fuel elements by absorbers, since the fuel elements are relatively small (diameter 5.15mm, uranium 235 content 7.14g) and there are more then 3800 elements in the core. Nevertheless, replacing decreases the fuel burnup and its consumption. In the PIK fuel assembles a little part of the volume is occupied by the dumb elements to create a complete package of the assembles shroud, that is necessary in the hydraulic reasons. In the presented report the assessment of such a replacement is done. As a burnable material Gadolinium was selected. The measurements or the beginning of cycle were performed on the critical facility PIK. The burning calculation was confirmed by measurements on the 18MW reactor WWR-M. The results give the opportunity to twice the cycle duration. The proposed modification of the fuel assembles does not lead to alteration in the other reactor systems, but it touch the burned fuel reprocessing technology. (author)

Expression of activated PIK3CA in ovarian surface epithelium results in hyperplasia but not tumor formation.

Directory of Open Access Journals (Sweden)

Shun Liang

Full Text Available The Phosphatidylinositol 3'-kinase is a key regulator in various cancer-associated signal transduction pathways. Genetic alterations of its catalytic subunit alpha, PIK3CA, have been identified in ovarian cancer. Our in vivo data suggests that PIK3CA activation is one of the early genetic events in ovarian cancer. However, its role in malignant transformation of ovarian surface epithelium (OSE is largely unclear.Using the Müllerian inhibiting substance type II receptor (MISIIR promoter, we generated transgenic mice that expressed activated PIK3CA in the Müllerian epithelium. Overexpression of PIK3CA in OSE induced remarkable hyperplasia, but was not able to malignantly transform OSE in vivo. The consistent result was also observed in primary cultured OSEs. Although enforced expression of PIK3CA could not induce OSE anchorage-independent growth, it significantly increased anchorage-independent growth of OSE transformed by mutant K-ras.While PIK3CA activation may not be able to initiate OSE transformation, we conclude that activation of PIK3CA may be an important molecular event contributing to the maintenance of OSE transformation initiated by oncogenes such as K-ras.

Full Text Available Triple Negative Breast Cancer (TNBC accounts for 12-24% of all breast carcinomas, and shows worse prognosis compared to other breast cancer subtypes. Molecular studies demonstrated that TNBCs are a heterogeneous group of tumors with different clinical and pathologic features, prognosis, genetic-molecular alterations and treatment responsivity. The PI3K/AKT is a major pathway involved in the regulation of cell survival and proliferation, and is the most frequently altered pathway in breast cancer, apparently with different biologic impact on specific cancer subtypes. The most common genetic abnormality is represented by PIK3CA gene activating mutations, with an overall frequency of 20-40%. The aims of our study were to investigate PIK3CA gene mutations on a large series of TNBC, to perform a wider analysis on genetic alterations involving PI3K/AKT and BRAF/RAS/MAPK pathways and to correlate the results with clinical-pathologic data.PIK3CA mutation analysis was performed by using cobas® PIK3CA Mutation Test. EGFR, AKT1, BRAF, and KRAS genes were analyzed by sequencing. Immunohistochemistry was carried out to identify PTEN loss and to investigate for PI3K/AKT pathways components.PIK3CA mutations were detected in 23.7% of TNBC, whereas no mutations were identified in EGFR, AKT1, BRAF, and KRAS genes. Moreover, we observed PTEN loss in 11.3% of tumors. Deregulation of PI3K/AKT pathways was revealed by consistent activation of pAKT and p-p44/42 MAPK in all PIK3CA mutated TNBC.Our data shows that PIK3CA mutations and PI3K/AKT pathway activation are common events in TNBC. A deeper investigation on specific TNBC genomic abnormalities might be helpful in order to select patients who would benefit from current targeted therapy strategies.

The introduction of a new progestin-only oral contraceptive in Europe has renewed interest in this class of oral contraceptives. Unlike the more widely used combined oral contraceptives containing an estrogen plus progestin, these pills contain only a progestin (progestogen) and are taken without interruption. How these pills compare to others in their class or to combined oral contraceptives is not clear. This review examined randomized controlled trials of progestin-only pills for differences in efficacy, acceptability, and continuation rates. Through October 2013, we searched the computerized databases MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), POPLINE, and LILACS for studies of progestin-only pills. We also searched for current trials via ClinicalTrials.gov and ICTRP. Previous searches also included EMBASE. We included all randomized controlled trials in any language that included progestin-only pills for contraception.  We incorporated any comparison with a progestin-only pill; this could include different doses, other progestin-only pills, combined oral contraceptives, or other contraceptives. The first author abstracted the data and entered the information into RevMan 5. Another author performed a second, independent data abstraction to verify the initial data entry.We attempted to extract life-table rates (actuarial or continuous) and used the rate difference as the effect measure. Where life-table rates were not published, we used the incidence rate ratio (ratio of Pearl rates). Where only the crude number of events was published, we calculated the Peto odds ratio with 95% confidence interval (CI) using a fixed-effect model. For continuous variables, the mean difference (MD) was computed with 95% CI. Because of disparate exposures, we were not able to combine studies in meta-analysis. Six trials met the inclusion criteria. We have not found any new studies since the initial review. In the trial comparing the desogestrel versus

The state of the PIK reactor construction

Principle concepts of the PIK reactor project were stated late in the 60's but its construction was started in 1976. By the year 1986 the initial project was realised by approximately 70% but then, after Chernobyl accident the construction was essentially frozen to adjust the project to the revised nuclear safety regulations. The revised project was approved only in 1990 when the country was on the threshold of serious economic problems. The PIK reactor is a source of neutrons placed in the heavy water reflector. The fuel is uranium-235 (90% enrichment) of total weight 27 kg. Light water is used as moderator and coolant. Design parameters: thermal power is 100 W; thermal neutron flux in the reflector is 1.2x10 15 n/cm 2 s; in the central vertical beam tube is 5x10 15 n/cm 2 s; number of horizontal beam tubes is 10; diameter of beam tubes is 10 cm, with the possibility of replacement with beam tubes up to 25 cm in diameter. The reactor will be equipped with sources of hot, cold, and ultracold neutrons to obtain beams in different intervals of energy spectrum. The low temperature circuit will enable to irradiate samples at helium temperatures. The reactor has three series cooling circuits. Emergency core cooling systems in LOCA are double and in emergency power supply system is triple. The PIK reactor has no single common containment but four separate systems: for pipelines and units of the first circuit, for heavy water reflector, for operating hall, and for experimental beam tubes hall

Full Text Available Supposedly herbal weight loss pills are sold online and are widely used in the world. Some of these products are found to contain sibutramine by FDA and their sale is prohibited. We report a case of a female patient who presented to the emergency department after taking slimming pills. 17-year-old female patient presented to the emergency room with palpitations, dizziness, anxiety, and insomnia. She stated that she had taken 3 pills named La Jiao Shou Shen for slimming purposes during the day. Her vital signs revealed tachycardia. On her physical examination, she was restless, her oropharynx was dry, her pupils were mydriatic, and no other pathological findings were found. Sibutramine intoxication was suspected. She was given 5 mg IV diazepam for restlessness. After supportive therapy and observation in emergency department for 12 hours there were no complications and the patient was discharged home. Some herbal pills that are sold online for weight loss have sibutramine hidden as an active ingredient, and their sale is prohibited for this reason. For people who use herbal weight loss drugs, sibutramine excessive intake should be kept in mind at all times.

Highlights: • miR-375 is downregulated in colorectal cancer cell lines and tissues. • miR-375 inhibits colorectal cancer cell growth by targeting PIK3CA. • miR-375 inhibits colorectal cancer cell growth in xenograft nude mice model. - Abstract: Colorectal cancer (CRC) is the second most common cause of death from cancer. MicroRNAs (miRNAs) represent a class of small non-coding RNAs that control gene expression by triggering RNA degradation or interfering with translation. Aberrant miRNA expression is involved in human disease including cancer. Herein, we showed that miR-375 was frequently down-regulated in human colorectal cancer cell lines and tissues when compared to normal human colon tissues. PIK3CA was identified as a potential miR-375 target by bioinformatics. Overexpression of miR-375 in SW480 and HCT15 cells reduced PIK3CA protein expression. Subsequently, using reporter constructs, we showed that the PIK3CA untranslated region (3′-UTR) carries the directly binding site of miR-375. Additionally, miR-375 suppressed CRC cell proliferation and colony formation and led to cell cycle arrest. Furthermore, miR-375 overexpression resulted in inhibition of phosphatidylinositol 3-kinase (PI3K)/Akt signaling pathway. SiRNA-mediated silencing of PIK3CA blocked the inhibitory effect of miR-375 on CRC cell growth. Lastly, we found overexpressed miR-375 effectively repressed tumor growth in xenograft animal experiments. Taken together, we propose that overexpression of miR-375 may provide a selective growth inhibition for CRC cells by targeting PI3K/Akt signaling pathway.

However, little has been reported regarding the clinicopathological significance of PIK3CA expression in diffuse large B cell lymphoma (DLBCL. In the present study, we investigated the clinicopathological significance of PIK3CA in DLBCL by performing immunohistochemical evaluation of PIK3CA in tissue microarrays consisting of 199 cases of DLBCL. Kaplan–Meier survival analysis was performed to analyze the association between PIK3CA expression and overall prognosis. To further investigate the role of PIK3CA mediated in the proliferation, cell cycle and apoptosis of DLBCL cells, Cell Counting Kit-8 (CCK-8 and flow cytometry assays were carried out in DLBCL cell lines after successful, stable knockdown of PIK3CA using lentiviral short hairpin RNA inference. Our results indicated that although PIK3CA was shown to be extensively expressed in DLBCL, no significant association was observed between PIK3CA expression and clinical outcome or between PIK3CA expression and other clinicopathological parameters, except between performance state (PS

Background Pills (tablets and capsules) are widely used to administer prescription drugs or to take supplements such as vitamins. Unfortunately, little is known about how much effort it takes Americans to swallow these various pills. More specifically, it is not known to what extent hard-to-swallow pills might affect treatment outcomes (eg, interfering with adherence to prescribed medications or causing clinical complications). It is also unclear which properties (eg, size, shape, or surface texture) Americans prefer or reject for their pills. To learn more about these issues, we interviewed a small group of individuals. Methods We invited individuals in waiting rooms of our tertiary health care center to participate in structured interviews about their pill-taking habits and any problems they have swallowing pills. We inquired which pill properties they believed caused swallowing problems. Participants scored capsules and pills of representative size, shape, and texture for swallowing effort and reported their personal preferences. Results Of 100 successive individuals, 99 participants completed the interview (65% women, mean age = 41 years, range = 23-77 years). Eighty-three percent took pills daily (mean 4 pills/d; 56% of those pills were prescribed by providers). Fifty-four percent of participants replied yes to the question, "Did you ever have to swallow a solid medication that was too difficult?" Four percent recounted serious complications: 1% pill esophagitis, 1% pill impaction, and 2% stopped treatments (antibiotic and prenatal supplement) because they could not swallow the prescribed pills. Half of all participants routinely resorted to special techniques (eg, plenty of liquids or repeated or forceful swallows). Sixty-one percent of those having difficulties cited specific pill properties: 27% blamed size (20% of problems were caused by pills that were too large whereas 7% complained about pills that were too small to sense); 12% faulted rough surface

Phosphatidylinositol-3-kinase (PI3K)/AKT pathway aberrations are common in cancer. By applying mass spectroscopy-based sequencing and reverse phase protein arrays to 547 human breast cancers and 41 cell lines, we determined the subtype specificity and signaling effects of PIK3CA, AKT and PTEN mutations, and the effects of PIK3CA mutations on responsiveness to PI3K inhibition in-vitro and on outcome after adjuvant tamoxifen. PIK3CA mutations were more common in hormone receptor positive (33.8%) and HER2-positive (24.6%) than in basal-like tumors (8.3%). AKT1 (1.4%) and PTEN (2.3%) mutations were restricted to hormone receptor-positive cancers with PTEN protein levels also being significantly lower in hormone receptor-positive cancers. Unlike AKT1 mutations, PIK3CA (39%) and PTEN (20%) mutations were more common in cell lines than tumors, suggesting a selection for these but not AKT1 mutations during adaptation to culture. PIK3CA mutations did not have a significant impact on outcome in 166 hormone receptor-positive breast cancer patients after adjuvant tamoxifen. PIK3CA mutations, in comparison with PTEN loss and AKT1 mutations, were associated with significantly less and indeed inconsistent activation of AKT and of downstream PI3K/AKT signaling in tumors and cell lines, and PTEN loss and PIK3CA mutation were frequently concordant, suggesting different contributions to pathophysiology. PTEN loss but not PIK3CA mutations rendered cells sensitive to growth inhibition by the PI3K inhibitor LY294002. Thus, PI3K pathway aberrations likely play a distinct role in the pathogenesis of different breast cancer subtypes. The specific aberration may have implications for the selection of PI3K-targeted therapies in hormone receptor-positive breast cancer.

The phosphatidylinositol-3 kinase (PI3K)/Akt/mTOR signaling pathway is activated in many human cancers. Previously, we reported that patients with early stage cervical cancer whose tumours harbour PIK3CA exon 9 or 20 mutations have worse overall survival in response to treatment with radiation and cisplatin than patients with wild-type PIK3CA. The purpose of this study was to determine whether PIK3CA-E545K mutation renders cervical cancer cells more resistant to cisplatin and/or radiation, and whether PI3K inhibition reverses the phenotype. We found that CaSki cells that are heterozygous for the PIK3CA-E545K mutation are more resistant to cisplatin or cisplatin plus radiation than either HeLa or SiHa cells that express only wild-type PIK3CA. Similarly, HeLa cells engineered to stably express PIK3CA-E545K were more resistant to cisplatin or cisplatin plus radiation than cells expressing only wild-type PIK3CA or with PIK3CA depleted. Cells expressing the PIK3CA-E545K mutation also had constitutive PI3K pathway activation and increased cellular migration and each of these phenotypes was reversed by treatment with the PI3K inhibitor GDC-0941/Pictilisib. Our results suggests that cervical cancer patients whose tumours are positive for the PIK3CA-E545K mutation may benefit from PI3K inhibitor therapy in concert with standard cisplatin and radiation therapy.

Mutant PIK3CA Induces EMT in a Cell Type Specific Manner.

Directory of Open Access Journals (Sweden)

Divya Bhagirath

Full Text Available Breast cancer is characterized into different molecular subtypes, and each subtype is characterized by differential gene expression that are associated with distinct survival outcomes in patients. PIK3CA mutations are commonly associated with most breast cancer subtypes. More recently PIK3CA mutations have been shown to induce tumor heterogeneity and are associated with activation of EGFR-signaling and reduced relapse free survival in basal subtype of breast cancer. Thus, understanding what determines PIK3CA induced heterogeneity and oncogenesis, is an important area of investigation. In this study, we assessed the effect of mutant PIK3CA together with mutant Ras plus mutant p53 on oncogenic behavior of two distinct stem/progenitor breast cell lines, designated as K5+/K19- and K5+/K19+. Constructs were ectopically overexpressed in K5+/K19- and K5+/K19+ stem/progenitor cells, followed by various in-vitro and in-vivo analyses. Oncogene combination m-Ras/m-p53/m-PIK3CA efficiently transformed both K5+/K19- and K5+/K19+ cell lines in-vitro, as assessed by anchorage-independent soft agar colony formation assay. Significantly, while this oncogene combination induced a complete epithelial-to-mesenchymal transition (EMT in K5+/K19- cell line, mostly epithelial phenotype with minor EMT component was seen in K5+/K19+ cell line. However, both K5+/K19- and K5+/K19+ transformed cells exhibited increased invasion and migration abilities. Analyses of CD44 and CD24 expression showed both cell lines had tumor-initiating CD44+/CD24low cell population, however transformed K5+/K19- cells had more proportion of these cells. Significantly, both cell types exhibited in-vivo tumorigenesis, and maintained their EMT and epithelial nature in-vivo in mice tumors. Notably, while both cell types exhibited increase in tumor-initiating cell population, differential EMT phenotype was observed in these cell lines. These results suggest that EMT is a cell type dependent

Towards Automated and Objective Assessment of Fabric Pilling

Rocco Furferi

2014-10-01

Full Text Available Pilling is a complex property of textile fabrics, representing, for the final user, a non-desired feature to be controlled and measured by companies working in the textile industry. Traditionally, pilling is assessed by visually comparing fabrics with reference to a set of standard images, thus often resulting in inconsistent quality control. A number of methods using machine vision have been proposed all over the world, with almost all sharing the idea that pilling can be assessed by determining the number of pills or the area occupied by the pills on the fabric surface. In the present work a different approach is proposed: instead of determining the number of pills, a machine vision-based procedure is devised with the aim of extracting a number of parameters characterizing the fabric. These are then used to train an artificial neural network to automatically grade the fabrics in terms of pilling. Tested against a set of differently pilled fabrics, the method shows its effectiveness.

The PIK3CA H1047R mutation is considered to be a potential predictive biomarker for EGFR-targeted therapies. In this study, we developed a novel PCR-PFLP approach to detect the PIK3CA H1047R mutation in high effectiveness. A 126-bp fragment of PIK3CA exon-20 was amplified by PCR, digested with FspI restriction endonuclease and separated by 3 % agarose gel electrophoresis for the PCR-RFLP analysis. The mutant sequence of the PIK3CA H1047R was spiked into the corresponding wild-type sequence in decreasing ratios for sensitivity analysis. Eight-six cases of formalin-fixed paraffin-embedded colorectal cancer (CRC) specimens were subjected to PCR-RFLP to evaluate the applicability of the method. The PCR-RFLP method had a capability to detect as litter as 0.4 % of mutation, and revealed 16.3 % of the PIK3CA H1047R mutation in 86 CRC tissues, which was significantly higher than that discovered by DNA sequencing (9.3 %). A positive association between the PIK3CA H1047R mutation and the patients’ age was first found, except for the negative relationship with the degree of tumor differentiation. In addition, the highly sensitive detection of a combinatorial mutation of PIK3CA, KRAS and BRAF was achieved using individual PCR-RFLP methods. We developed a sensitive, simple and rapid approach to detect the low-abundance PIK3CA H1047R mutation in real CRC specimens, providing an effective tool for guiding cancer targeted therapy

Full Text Available Despite a wealth of preclinical studies, it is unclear whether PIK3CA or phosphatase and tensin homolog (PTEN gene aberrations are actionable in the clinical setting. Of 1,656 patients with advanced, refractory cancers tested for PIK3CA or PTEN abnormalities, PIK3CA mutations were found in 9% (146/1,589, and PTEN loss and/or mutation was found in 13% (149/1,157. In multicovariable analysis, treatment with a phosphatidylinositol 3-kinase (PI3K/AKT/mammalian target of rapamycin (mTOR inhibitor was the only independent factor predicting response to therapy in individuals harboring a PIK3CA or PTEN aberration. The rate of stable disease ≥6 months/partial response reached 45% in a subgroup of individuals with H1047R PIK3CA mutations. Aberrations in the PI3K/AKT/mTOR pathway are common and potentially actionable in patients with diverse advanced cancers. This work provides further important clinical validation for continued and accelerated use of biomarker-driven trials incorporating rational drug combinations.

Lung cancer is the leading cause of cancer-related death worldwide. Genetic and epigenetic alterations have been identified frequently in lung cancer, such as promoter methylation, gene mutations and genomic amplification. However, the interaction between genetic and epigenetic events and their significance in lung tumorigenesis remains poorly understood. We determined the promoter methylation of 6 genes and PIK3CA amplification using quantitative methylation-specific PCR (Q-MSP) and real-time quantitative PCR, respectively, and explore the association of promoter methylation with PIK3CA amplification in a large cohort of clinically well-characterized non-small cell lung cancer (NSCLC). Highly frequent promoter methylation was observed in NSCLC. With 100% diagnostic specificity, excellent sensitivity, ranging from 45.8 to 84.1%, was found for each of the 6 genes. The promoter methylation was associated with histologic type. Methylation of CALCA, CDH1, DAPK1, and EVX2 was more common in squamous cell carcinomas (SCC) compared to adenocarcinomas (ADC). Conversely, there was a trend toward a higher frequency of RASSF1A methylation in ADC than SCC. In addition, PIK3CA amplification was frequently found in NSCLC, and was associated with certain clinicopathologic features, such as smoking history, histologic type and pleural indentation. Importantly, aberrant promoter methylation of certain genes was significantly associated with PIK3CA amplification. Our data showed highly frequent promoter methylation and PIK3CA amplification in Chinese NSCLC population, and first demonstrated the associations of gene methylation with PIK3CA amplification, suggesting that these epigenetic events may be a consequence of overactivation of PI3K/Akt pathway

This report includes the final project results of the two groups at PIK, involved in the project: Firstly, the newly developed physiologically-based forest growth model FORSANA was applied for the first time to three pine stands, which differed largely in their air pollution and deposition history. (The evaluation of the model is presented in PIK Report 32). The model was able to explain the growth during the last decades of at least two of the three stands from the climatic and deposition conditions at the sites. The third site was shown to be exceptional with respect to its relation between dimension and age, and was supposed to be exposed to major disturbances in the past, which could not be accounted for by the model. To extrapolate from the stand level to the regional level, FORSANA was initialised with spatially explicit data from forestry inventory and soil maps. Simulations were executed with measured weather records and regional distributions of deposition and air pollution, which were estimated on the basis of emission inventories and wind directions. Different assumptions about the development of air pollution had been applied to investigate different pollution abatement strategies. The results showed that a positive effect can be expected from the actual emission reductions close the main centres of emission, but showed also that this effect is decreasing with increasing distance from the emission source.

Recent genomic evidence suggests frequent phosphatidylinositide 3-kinase (PI3K) pathway activation in human papillomavirus (HPV) positive oropharyngeal squamous cell carcinoma. Mutations/amplification of the gene encoding p110α catalytic subunit of phosphoinositide 3-kinase (PIK3CA), loss of phosphatase and tensin homolog (PTEN) and HRAS mutations are known to activate PI3K pathway. PIK3CA mutations were identified by Sanger sequencing in 23 of 75 (31%) HPV-positive oropharyngeal carcinomas, including exon 9 (p.E545K [n = 10] and p.E542K [n = 5]) or exon 20 (p.H1047Y, n = 2) mutations. Five rare and one novel (p.R537Q) PIK3CA mutations were identified. HRAS mutation (p.Q61L) was detected in 1 of 62 tested cases. PIK3CA amplification by fluorescence in situ hybridization (FISH) was identified in 4 cases (4/21, 20%), while PTEN loss was seen in 7 (7/21, 33%) cases (chromosome 10 monosomy [n = 4], homozygous deletion [n = 3]). Overall, genetic alterations that likely lead to PI3K pathway activation were identified in 34 of 75 cases (45%) and did not correlate with disease specific survival. These findings offer a molecular rationale for therapeutic targeting of PI3K pathway in patients with HPV-positive oropharyngeal carcinoma

Full Text Available The phosphatidylinositol 3-kinases (PIK3s are lipid kinases. Mutation in the exon 9 and exon 20 determined as a predictive factor in anti-HER-2 therapy. In some countries, such as Singapore, China, and Peru, PIK3CA exon 9 E545A was reported to produce the highest rate of mutation. In this research, we developed and optimized PIK3CA exon 9 E545A detection methods with intercalating dye SYBR Green I based on the Tm Shift approach by using prepared recombinant plasmid pGEMT-easy PIK3CA exon 9 and PIK3CA exon 9 E545A. Recombinant plasmid was used due to the limited number of samples. Methods: Recombinant plasmid was prepared based on manufactured procedures, and this process was then followed by Tm prediction with Poland software, Tm Shift SYBR Green I development, and its characterization (reproducibility, repeatability, sensitivity, qPCR efficiency, and qPCR amplification, respectively. Result: A method for PIK3CA E545A detection based on TM shift SYBR Green I has been successfully developed. The melting temperature for PIK3CA exon 9 was 78.1 ± 0.1 °C, while that for PIK3CA exon E545A was 80.20 °C. The Tm of mutant was the same as that predicted using Polland Software. The reproducibility of the methods was high, with the coefficient values for inter and intra assays were below 10% with a high sensitivity at 1%, while R2 0.99 and PCR efficiency was 97.75%. Conclusion: The results presented here demonstrate that the PIK3CA exon 9 E545A detection method has a good sensitivity and efficacy assay, which proves that the method has a high diagnostic accuracy in breast cancer.

Full Text Available The PI3K-AKT pathway is frequently activated in breast cancer. PIK3CA mutations are most frequently found in the helical (exon 9 and kinase (exon 20 domains of this protein. The aim of the present study was to examine the role of different types of PIK3CA mutations in combination with molecular biomarkers related to PI3K-AKT signaling in patients with early breast cancer.Tumor tissue samples from 1008 early breast cancer patients treated with adjuvant chemotherapy in two similar randomized trials of HeCOG were examined. Tumors were subtyped with immunohistochemistry (IHC and FISH for ER, PgR, Ki67, HER2 and androgen receptor (AR. PIK3CA mutations were analyzed by Sanger sequencing (exon 20 and qPCR (exon 9 (Sanger/qPCR mutations. In 610 cases, next generation sequencing (NGS PIK3CA mutation data were also available. PIK3CA mutations and PTEN protein expression (IHC were analyzed in luminal tumors (ER and/or PgR positive, molecular apocrine carcinomas (MAC; ER/PgR negative / AR positive and hormone receptor (ER/PgR/AR negative tumors.PIK3CA mutations were detected in 235/1008 tumors (23% with Sanger/qPCR and in 149/610 tumors (24% with NGS. Concordance between the two methods was good with a Kappa coefficient of 0.76 (95% CI 0.69-0.82. Lobular histology, low tumor grade and luminal A tumors were associated with helical domain mutations (PIK3CAhel, while luminal B with kinase domain mutations (PIK3CAkin. The overall incidence of PIK3CA mutations was higher in luminal as compared to MAC and hormone receptor negative tumors (p = 0.004. Disease-free and overall survival did not significantly differ with respect to PIK3CA mutation presence and type. However, a statistically significant interaction between PIK3CA mutation status and PTEN low protein expression with regard to prognosis was identified.The present study did not show any prognostic significance of specific PIK3CA mutations in a large group of predominantly lymph-node positive breast cancer

Tibetan Precious Pills as Therapeutics and Rejuvenating Longevity Tonics

Directory of Open Access Journals (Sweden)

Barbara Gerke

2017-12-01

Full Text Available Tibetan precious pills are frequently attributed with a variety of efficacies, from “magical” powers, prevention of poisoning and infectious diseases, protection from harmful spirits and exposure to diseases while travelling, to rejuvenating and prolonging life through clearing the senses and promoting strength and vigor. They are prescribed as strong medicines for severe diseases, but are also advertised as rejuvenating tonics for the healthy. This paper explores the rejuvenating qualities attributed to precious pills in terms of how they are currently advertised, how rejuvenation is and has been explained in Tibetan works on precious pills, and how Tibetan physicians understand these attributes. How do these domains interact and refer to each other? I compare aspects of rejuvenation in precious pill formulas with contemporary presentations of precious pills online and on published leaflets given out to patients in India and elsewhere. In Tibetan medical texts certain precious pills that contain the complex and processed mercury-sulfide ash called tsotel in addition to a large variety of other medicinal substances are presented as “precious pills” or rinchen rilbu, and only some of those are said to have rejuvenating effects on the body; most are primarily prescribed for specific diseases. The practice of giving precious pills to the healthy emerges more prominently in eighteenth to nineteenth century manuals on administering precious pills (Czaja 2015, which parallels the establishment of influential medical and monastic networks that promoted the making of tsotel and precious pills. I argue that precious pills have more recently widened their specific therapeutic target beyond that of medicine into becoming popular pills for rejuvenation, even if they do not contain tsotel, as part of pharmaceutical commodification. I also show how presentations of precious pills as “rejuvenating” are deeply linked to their availability.

Overgrowth syndromes are characterized by global or localized disproportionate growth associated with other anomalies, including vascular malformations and neurological and/or visceral disorders. CLOVES (Congenital Lipomatous asymmetric Overgrowth of the trunk with lymphatic, capillary, venous, and combined-type Vascular malformations, Epidermal naevi, Scoliosis/Skeletal and spinal anomalies) is an overgrowth syndrome caused by mosaic activating mutation in gene PIK3CA, which gives rise to abnormal PI3K-AKT-mTOR pathway activation. These mutations are responsible for the clinical manifestations of the syndrome, which include low- and high-flow vascular malformations, thoracic lipomatous hyperplasia, asymmetric growth, and visceral and neurological disorders. These common anomalies are illustrated with figures from two personal cases. Identification of the clinical and genetic characteristics of CLOVES syndrome is crucial for the differential diagnosis with other overgrowth syndromes, such as Proteus or Klippel-Trenaunay (K-T) syndromes, and for the therapeutic management of the different anomalies. In this context, a new entity comprising different syndromes with phenotypic mutations in PIK3CA has been proposed, designated PIK3CA-related overgrowth spectrum (PROS), with the aim of facilitating clinical management and establishing appropriate genetic study criteria. © 2016 John Wiley & Sons A/S.

A liquid control element (LCE) containing a water solution of gadolinium nitrate Gd(NO 3 ) 3 was originally planned for use at the PIK reactor for partial compensation of poisoning and fuel burnup [1-3]. However, a further analysis has shown that quick forcing-out, boiling up or flowing-out of the absorbing solution (though of low probability) can lead to the dangerous prompt overcriticality of the reactor. The results of the analysis are presented as well as the upper limit of the reactivity, quick insertion of which still is safe for the reactor (J.P.N.)

The Return of Rainbow Diet Pills

2012-01-01

The US Food and Drug Administration (FDA) has recently warned consumers about the risks of weight loss supplements adulterated with multiple pharmaceutical agents. Some of these supplements combine potent anorectics, such as amphetamines derivatives, with benzodiazepines, beta-blockers, and other medications to suppress the anorectics’ adverse effects. These weight loss supplements represent the most recent generation of rainbow diet pills, named for their bright and varied colors, which date back more than 70 years. Beginning in the 1940s, several US pharmaceutical firms aggressively promoted rainbow pills to physicians and patients. By the 1960s the pills had caused dozens of deaths before the FDA began removing them from the US market. We used a variety of original resources to trace these deadly pills from their origins in the United States to their popularity in Spain and Brazil to their reintroduction to the United States as weight loss dietary supplements.

According to large-scale studies, oral contraceptive users become pregnant at rates that exceed ideal use failure rates. It is thought that a major cause is missed pills, but current research on consistent contraceptive pill taking is characterized by inadequate measures and a failure to investigate women's thinking about their own patterns of use. The purpose of this study was to gain some understanding about women's interpretations of consistency in their own pill taking through combining qualitative with quantitative data. The study was conducted in China, where contraception is free and widely available. Five urban and five rural oral contraceptive users were followed for up to three pill-taking cycles during 1996 for a total of 759 person-days. Consistency of pill taking was measured with electronic data obtained from a new blister package made by Anderson Clinical Technologies (Elmhurst, IL). Data from these devices were reviewed and interpreted by the study participants during in-depth private interviews. The users' reasons for missing pills included disruptions in their daily routines, their husband's absence, spotting, and trouble implementing the family planning program's instructions to take one pill per day for 22 days and start the next cycle on the fifth day of menses. One user gave these reasons for two cycles but denied missing numerous pills in her third cycle. Data from a series of four questionnaires showed that most demographic, psychosocial, and service system characteristics were not related to missed pills. However, results suggested that the daily routines of rural living may make consistent use more likely and that instructions for taking the pill may be associated with prolonged pill-free intervals and skipping pills during episodes of spotting. Three of the 10 women were at increased risk of pregnancy during the study period because of their pill-taking pattern. We concluded that the combination of qualitative with quantitative data

The Administration of Tibetan Precious Pills

Czaja, Olaf

2016-01-01

Precious pills represent a special kind of Tibetan drug that once was, and still is, highly sought after by Tibetan, Chinese, and Mongolian patients. Such pills are generally taken as a potent prophylactic remedy, and can be used to cure various diseases. The present study seeks to discuss the dispensation and efficacy of precious pills according to the presentations of historical Tibetan medical scholars. Several treatises dealing with these instructions will be analysed, thereby revealing their underlying concepts, and highlighting their points of both general consensus and disagreement. The analysis of these detailed instructions will reveal the fact that these precious pills were not merely given to a patient but, in order to ensure their full efficacy, involved an elaborate regimen concerning three chronological periods: (1) the time of preparation, (2) the time of dispensation, and (3) the time after dispensation. Thus the present study surveys not only the ritual empowerment of drugs in Tibetan medicine, but also the importance of social relationships between doctors and patients in Tibetan medical history.

2012-07-01

Full Text Available Previous research has linked poison pill to corporate governance characteristics such as ownership structure and board composition while overlooking the attributes of top managers involved in poison pill decision. Based on upper echelons perspective, we changed the focus by investigating the effect of CEO characteristics on poison pills, as measured by age, business education, and outside directorships. Using a sample of Fortune 500 manufacturing firms, we found that CEO business education is positively associated with poison pills, while CEOs’ outside directorships are negatively associated with poison pills. Furthermore, we found that CEO duality moderates the relationship between CEO business education and poison pills. We make implications for both corporate governance research and managerial practices regarding firms’ anti-takeover provisions.

PIK3CA, the gene coding for the p110α subunit of phosphoinositide 3-kinase, is frequently mutated in a variety of human tumors including breast cancers. To better understand the role of mutant PIK3CA in the initiation and/or progression of breast cancer, we have generated mice with a conditional knock-in of the common activating mutation, Pik3caH1047R, into one allele of the endogenous gene in the mammary gland. These mice developed a ductal anaplasia and hyperplasia by 6 weeks of age characterized by multi-layering of the epithelial lining of the mammary ducts and expansion of the luminal progenitor (Lin−; CD29lo; CD24+; CD61+) cell population. The Pik3caH1047R expressing mice eventually develop mammary tumors with 100% penetrance but with a long latency (>12 months). This is significantly longer than has been reported for transgenic models where expression of the mutant Pik3ca is driven by an exogenous promoter. Histological analysis of the tumors formed revealed predominantly ERα-positive fibroadenomas, carcinosarcomas and sarcomas. In vitro induction of Pik3caH1047R in immortalized mammary epithelial cells also resulted in tumor formation when injected into the mammary fat pad of immunodeficient recipient mice. This novel model, which reproduces the scenario of a heterozygous somatic mutation occurring in the endogenous PIK3CA gene, will thus be a valuable tool for investigating the role of Pik3caH1047R mutation in mammary tumorigenesis both in vivo and in vitro.

Intimate partner violence is widespread worldwide. While assumed to impact women's ability to use contraceptive methods, few data are available to support this claim. In this study, eight focus group discussions were conducted to guide questionnaire development and to provide contextual information. Participants were women who were currently using the pill and women who had used the pill previously. In addition, 300 women were interviewed who initiated oral contraceptive pill use between December 1995 and April 1996. Participants were interviewed 3-6 months later to investigate the role intimate partner violence played in covert pill use and pill discontinuation. Special study procedures for asking women questions about violence were employed. Nineteen per cent of the women interviewed were using the pill covertly. The odds of covert pill use were four times higher in El Alto and La Paz than in Santa Cruz. Women who used the pill covertly were more likely to have experienced method-related partner violence (OR = 21.27) than women whose partners knew of their pill use. One-third of the women had discontinued pill use at the time of the interview. In the final multivariate analysis, having experienced side-effects (OR = 2.37) was a significant predictor of pill discontinuation and method-related partner violence was marginally predictive (OR = 1.91; 95% CI 1.0-3.66). While efforts are ongoing to incorporate men into family planning programmes, some male partners oppose, and in some situations violently oppose, contraceptive use. The needs of women with these types of partners must not be overlooked.

Imported fenproporex-based diet pills from Brazil: a report of two cases.

Banned amphetamine-based anorectics are illicitly imported into the United States (US), but little is known regarding the harm these diet pills pose to US residents. A 26-year-old woman using imported diet pills presented with a two-year history of intermittent chest pains, palpitations, headaches and insomnia. Urine toxicology screen detected amphetamines and benzodiazepines. Fenproporex and chlordiazepoxide were detected in her pills. Her symptoms resolved after she stopped using diet pills. A 38-year-old man using imported diet pills presented after his occupational urine screen was significantly positive for amphetamine. Fenproporex and fluoxetine were detected in his pills. These cases illustrate the potential harm from imported prescription diet pills that combine fenproporex with benzodiazepines, antidepressants, diuretics, laxatives and other substances. Increasing physicians' awareness of imported diet pill use may improve care of patients suffering from the pills' many adverse effects.

Oral hormonal contraception is an effective contraceptive method as long as regular daily intake is maintained. However, a daily routine is a constraint for many women and can lead to missed pills, pill discontinuation and/or unintended pregnancy. This article describes the frequency of inconsistent use, the consequences, the risk factors and the possible solutions. The article comprises a narrative review of the literature. Forgetting one to three pills per cycle is a frequent problem among 15-51% of users, generally adolescents. The reasons for this are age, inability to establish a routine, pill unavailability, side effects, loss of motivation and lack of involvement in the initial decision to use oral contraceptives. The consequences are 'escape ovulations' and, possibly, unintended pregnancy. Solutions are either to use a long-acting method or, for women who prefer to take oral contraceptives, use a continuous or long-cycle regimen to reduce the risks of follicular development and thus the likelihood of ovulation and unintended pregnancy. A progestogen with a long half-life can increase ovarian suppression. For women deciding to use oral contraceptives, a shortened or eliminated hormone-free interval and a progestogen with a long half-life may be an option to reduce the negative consequences of missed oral contraceptive pills.

Full Text Available Knitted fabrics with different quantity of elastane, conspicuous by high viscosity and elasticity, having one of the most important performance properties - resistance to pilling are often used in the production of high quality sportswear. During technological process imitating operating conditions, the behaviour of knitted fabrics may be changed by different industrial softeners from 12 % to 20 % of active substance, for example fatty acid condensate (Tubingal 5051 or silicone micro emulsion (Tubingal SMF. The aim of this investigation is to define the influence of fibrous composition and chemical softeners to the propensity of fuzzing and pilling of plain and plated jersey pattern knitted fabrics. The results of investigations showed that fibrous composition and thickness of materials (up to 6 % and washing as well as softening (from 33 % to 67 % change the resistance of knitted fabrics to pilling.http://dx.doi.org/10.5755/j01.ms.17.3.597

Although other methods exist for monitoring gastrointestinal motility and contractility, this study exclusively provides direct and quantitative measurements of the forces experienced by an orally ingested pill. We report motive forces and torques calculated from real-time, in vivo measurements of the movement of a magnetic pill in the stomachs of fasted and fed humans. Three-dimensional net force and two-dimensional net torque vectors as a function of time data during gastric residence are evaluated using instantaneous translational and rotational position data. Additionally, the net force calculations described can be applied to high-resolution pill tracking acquired by any modality. The fraction of time pills experience ranges of forces and torques are analyzed and correlate with the physiological phases of gastric digestion. We also report the maximum forces and torques experienced in vivo by pills as a quantitative measure of the amount of force pills experience during the muscular contractions leading to gastric emptying. Results calculated from human data are compared with small and large animal models with a translational research focus. The reported magnitude and direction of gastric forces experienced by pills in healthy stomachs serves as a baseline for comparison with pathophysiological states. Of clinical significance, the directionality associated with force vector data may be useful in determining the muscle groups associated with gastrointestinal dysmotility. Additionally, the quantitative comparison between human and animal models improves insight into comparative gastric contractility that will aid rational pill design and provide a quantitative framework for interpreting gastroretentive oral formulation test results.

The last iodine pills were distributed in february 2009, they are now outdated and a new campaign has been launched. Each family will receive a voucher to recover iodine pills from the nearby pharmacy. The aim of this new campaign is of course to protect people in case of severe nuclear accident but also to develop a radiation protection culture among the population. During the previous campaign only 51% of the concerned people went to the pharmacy to get the pills. The 2016 campaign will involve the public and all the establishments open to the public in a range of 10 km around each of the 19 nuclear power plants. It concerns 500 municipalities, 375.000 households, 55.000 enterprises and public utilities and 275 pharmacies are involved in the campaign. (A.C.)

The decrease in utility attributed to taking pills for cardiovascular prevention can have major effects on the cost-effectiveness of interventions but has not been well studied. We sought to measure the utility of daily pill-taking for cardiovascular prevention. We conducted a cross-sectional Internet-based survey of 1000 US residents aged ≥30 in March 2014. We calculated utility values, using time trade-off as our primary method and standard gamble and willingness-to-pay techniques as secondary analyses. Mean age of respondents was 50 years. Most were female (59%) and white (63%); 28% had less than a college degree; and 79% took ≥1 pills daily. Mean utility using the time trade-off method was 0.990 (95% confidence interval, 0.988-0.992), including ≈70% not willing to trade any amount of time to avoid taking a preventive pill daily. Using the standard gamble method, mean utility was 0.991 (0.989-0.993), with 62% not willing to risk any chance of death. Respondents were willing to pay an average of $1445 to avoid taking a pill daily, which translated to a mean utility of 0.994 (0.940-0.997), including 41% unwilling to pay any amount.

Cervical cancer is one of the most common causes of cancer mortality for women living in poverty, causing more than 28,000 deaths annually in Latin America and 266,000 worldwide. To better understand the molecular basis of the disease, we ascertained blood and tumor samples from Guatemala and Venezuela and performed genomic characterization. We performed human papillomavirus (HPV) typing and identified somatically mutated genes using exome and ultra-deep targeted sequencing with confirmation in samples from Mexico. Copy number changes were also assessed in the exome sequence. Cervical cancer cases in Guatemala and Venezuela have an average age of diagnosis of 50 years and 5.6 children. Analysis of 675 tumors revealed activation of PIK3CA and other PI3K/AKT pathway genes in 31% of squamous carcinomas and 24% of adeno- and adenosquamous tumors, predominantly at two sites (E542K, E545K) in the helical domain of the PIK3CA gene. This distribution of PIK3CA mutations is distinct from most other cancer types and does not result in the in vitro phosphorylation of AKT. Somatic mutations were more frequent in squamous carcinomas diagnosed after the age of 50 years. Frequent gain of chromosome 3q was found, and low PIK3CA mutation fractions in many tumors suggest that PI3K mutation can be a late event in tumor progression. PI3K pathway mutation is important to cervical carcinogenesis in Latin America. Therapeutic agents that directly target PI3K could play a role in the therapy of this common malignancy. ©2015 American Association for Cancer Research.

Opioid analgesics are commonly prescribed on an as-needed (PRN) basis for acute painful conditions. Uncertainty of how patients actually take PRN opioids, coupled with a desire to completely cover pain, leads to variable and overly generous opioid prescribing practices, resulting in a surplus of opioids. This opioid surplus becomes a source for diversion and nonmedical opioid use. Understanding patterns of actual opioid ingestion after acute painful conditions can help clinicians counsel patients on safe opioid use, and allow timely recognition and intervention when escalating opioid self-dosing occurs, to prevent tolerance and addiction. We used a novel oxycodone digital pill system (ingestible biosensor within a standard gelatin capsule combined with 5-mg oxycodone) that when ingested, is activated by the chloride ion gradient in the stomach thereby emitting a radiofrequency signal captured by a wearable reader. The reader relays ingestion data to a cloud-based server that displays ingestion events to the study team. We deployed the oxycodone digital pill among opioid-naive individuals discharged from the emergency department with acute fracture pain. Participants were trained on digital pill operation and discharged with twenty-one 5-mg oxycodone digital pills. They were instructed to take digital pills PRN for pain on discharge. We conducted a brief interview 7 days after study enrollment, at which point participants returned the digital pill system. We identified oxycodone ingestion events in real time by data from the digital pill system and performed pill counts at the return visit to validate digital pill reporting of medication ingestion. In this study, 26 individuals were approached; 16 enrolled with 15 completing the study. Participants ingested a median of 6 (3-9.5) oxycodone digital pills over the course of 7 days, with 82% of the oxycodone dose ingested in the first 3 days. In individuals who required operative repair, 86% (N = 6) continued to ingest

Background . Orally ingested medications now come in both immediate release and controlled release preparations. Controlled release preparations were developed by pharmaceutical companies to improve compliance and decrease frequency of pill ingestion. Case Report . A 67-year-old obese male patient presented to our clinic with focal abdominal pain that had been present 3 inches below umbilicus for the last three years. This pain was not associated with any trauma or recent heavy lifting. Upon presentation, the patient reported that for the last two months he started to notice pearly oval structures in his stool accompanying his chronic abdominal pain. This had coincided with initiation of his nifedipine pills for his hypertension. He reported seeing these undigested pills daily in his stool. Conclusion . The undigested pills may pose a cause of concern for both patients and physicians alike, as demonstrated in this case report, because they can mimic a parasitic infection. This can result in unnecessary extensive work-up. It is important to review the medication list for extended release formulations and note that the outer shell can be excreted whole in the stool.

Medical abortion is a safe method of termination of pregnancy when performed as per guidelines with a success rate of 92-97 %. But self-administration of abortion pills is rampant throughout the country due to over the counter availability of these drugs and complications are not uncommon due to this practice. The society perceives unsupervised medical abortion as a very safe method of termination and women use this as a method of spacing. The aim of this study was to study the implications of self-administration of abortion pills by pregnant women. Retrospective observational study done in Sri Manakula Vinayagar Medical College & Hospital between the period of July 2013 to June2014. Case sheets were analysed to obtain data regarding self-administration of abortion pills and complications secondary to its administration. The following data were collected. Age, marital status, parity, duration of pregnancy as perceived by the women, confirmation of pregnancy, duration between pill intake and visit to hospital, whether any intervention done elsewhere, any known medical or surgical complications, Hb level on admission, whether patient was in shock, USG findings, evidence of sepsis, blood transfusion, treatment given and duration of hospital stay. Descriptive analysis of the collected data was done. Among the 128 cases of abortion in the study period, 40 (31.25%) patients had self-administered abortion pills. Among these 40 patients 27.5% had consumed abortion pills after the approved time period of 63 days of which 17.5% had consumed pills after 12 weeks of gestation. The most common presentation was excessive bleeding (77.5%) Severe anaemia was found in 12.5% of the patients and 5% of patients presented with shock. The outcome was as follows : 62.5% of the patients were found to have incomplete abortion, 22.5% had failed abortion and 7.5% of patients had incomplete abortion with sepsis. Surgical evacuation was performed in 67.5% of the patients whereas 12.5% of the

Little is known about the frequency and patterns of use of emergency contraceptive pills among women in urban Kenya and Nigeria. To recruit women who had used emergency contraceptive pills, individuals aged 18-49 were intercepted and interviewed at shopping venues in Nairobi, Kenya, and Lagos, Nigeria, in 2011. Information was collected on 539 Nairobi and 483 Lagos respondents' demographic and behavioral characteristics, attitudes toward the method, and frequency of use. Multinomial logistic regression analyses were used to identify associations between these characteristics and frequency of pill use. Eighteen percent of the women interviewed in Nairobi and 17% in Lagos had ever used emergency contraceptive pills. On average, these respondents had used the pills less than once per month, but greater use and acceptance were seen in Lagos. In multivariate analysis, women who had sex at least once in a typical week were generally more likely than others to have used the pills 2-5 times in the last six months, rather than once or never, or to have used them six or more times. Furthermore, Lagos respondents who said their main contraceptive method was the condom, the pill or injectable, or a natural method were generally less likely than those who did not report these methods to have used the emergency pills multiple times in the last six months. Repeated use of emergency contraceptive pills was not common in this sample.

HER2/neu gene amplification and PIK3CA driver mutations are common in uterine serous carcinoma (USC), and may represent ideal therapeutic targets against this aggressive variant of endometrial cancer. We examined the sensitivity to neratinib, taselisib and the combination of the two compounds in in vitro and in vivo experiments using PIK3CA mutated and PIK3CA-wild type HER2/neu amplified USC cell lines. Cell viability and cell cycle distribution were assessed using flow-cytometry assays. Downstream signaling was assessed by immunoblotting. Preclinical efficacy of single versus dual inhibition was evaluated in vivo using two USC-xenografts. We found both single agent neratinib and taselisib to be active but only transiently effective in controlling the in vivo growth of USC xenografts harboring HER2/neu gene amplification with or without oncogenic PIK3CA mutations. In contrast, the combination of the two inhibitors caused a stronger and long lasting growth inhibition in both USC xenografts when compared to single agent therapy. Combined targeting of HER2 and PIK3CA was associated with a significant and dose-dependent increase in the percentage of cells in the G0/G1 phase of the cell cycle and a dose-dependent decline in the phosphorylation of S6. Importantly, dual inhibition therapy initiated after tumor progression in single agent-treated mice was still remarkably effective at inducing tumor regression in both large PIK3CA or pan-ErbB inhibitor-resistant USC xenografts. Dual HER2/PIK3CA blockade may represent a novel therapeutic option for USC patients harboring tumors with HER2/neu gene amplification and mutated or wild type PIK3CA resistant to chemotherapy.

The results of EPR studies on herbal pills of marigold, hawthorn, yarrow, common balm, tutsan, nettle and thyme before and after gamma-irradiation are reported. Before irradiation all samples exhibit one weak singlet EPR line with a g-factor of 2.0048{+-}0.0005. After irradiation herbal pills could be separated in two groups according to their EPR spectra. Radiation-induced free radicals in pills of marigold, yarrow, nettle, tutsan and thyme could be attributed mainly to saccharide excipients. Tablets of hawthorn and common balm show 'cellulose-like' EPR spectrum, superimposed on partly resolved carbohydrate spectrum, due to the active part (herb) and inulin, which is present in the pills as an excipient. Fading study of the radiation-induced EPR signals confirms that sugar radicals are more stable than cellulose species. The reported results show that the presence of characteristic EPR spectra of herbal pills due to excipients or active part can be used as unambiguous proof of radiation processing within 35 or more days after irradiation.

The PIK3CA gene at chromosome 3q26.32 was found to be amplified in up to 45% of patients with squamous cell carcinoma of the lung. The strong correlation between PIK3CA amplification and increased phosphatidylinositol 3-kinase (PI3K) pathway activities suggested that PIK3CA gene copy number is a potential predictive biomarker for PI3K inhibitors. Currently, all microscopic assessments of PIK3CA and chromosome 3 (CHR3) copy numbers use fluorescence in situ hybridization. PIK3CA probes are derived from bacterial artificial chromosomes whereas CHR3 probes are derived mainly from the plasmid pHS05. These manual fluorescence in situ hybridization assays mandate 12- to 18-hour hybridization and use of blocking DNA from human sources. Moreover, fluorescence in situ hybridization studies provide limited morphologic assessment and suffer from signal decay. We developed an oligonucleotide-based bright-field in situ hybridization assay that overcomes these shortcomings. This assay requires only a 1-hour hybridization with no need for blocking DNA followed by indirect chromogenic detection. Oligonucleotide probes produced discrete and uniform CHR3 stains superior to those from the pHS05 plasmid. This assay achieved successful staining in 100% of the 195 lung squamous cell carcinoma resections and in 94% of the 33 fine-needle aspirates. This robust automated bright-field dual in situ hybridization assay for the simultaneous detection of PIK3CA and CHR3 centromere provides a potential clinical diagnostic method to assess PIK3CA gene abnormality in lung tumors.

2016-08-01

Xiangsha Yangwei pill was selected as a model drug in this research, and time domain reflectometry (TDR) was used to determine the water content in the pill. The effects of five factors including the number of pill layers, pill packing density, atmospheric moisture, ambient temperature and the ratio of pill formula were investigated on water content. The results showed that the number of pill layers and ambient temperature had significant effects on water content of pills, while the pill packing density, atmospheric moisture and pill formula ratio had little effect on the determination of water content in pills. The reflection value was stable when 6 layers of pills were used. Under the condition of 25 ℃ and 45% relative humidity, the water content of pills ranged from 4.01% to 22.38%, showing good linear relationship between water content and reflection value, and the model equation was as follows: Y=0.279X－21.670 (R²=0.997 0). Verification experiment was used to explain the feasibility of this prediction model. The precision of the method complied with the methodology standard. It is concluded that TDR can be used in determination of water content in Xiangsha Yangwei pills. Additionally, TDR, as a new way to quickly and efficiently determine the water content, has a prospect application in the processing of traditional Chinese medicine pharmacy, especially for concentrated pill.

Monitoring Location and Angular Orientation of a Pill

Science.gov (United States)

Schipper, John F.

2012-01-01

A mobile pill transmitter system moves through, or adjacent to, one or more organs in an animal or human body, while transmitting signals from its present location and/or present angular orientation. The system also provides signals from which the present roll angle of the pill, about a selected axis, can be determined. When the location coordinates angular orientation and the roll angle of the pill are within selected ranges, an aperture on the pill container releases a selected chemical into, or onto, the body. Optionally, the pill, as it moves, provides a sequence of visually perceptible images. The times for image formation may correspond to times at which the pill transmitter system location or image satisfies one of at least four criteria. This invention provides and supplies an algorithm for exact determination of location coordinates and angular orientation coordinates for a mobile pill transmitter (PT), or other similar device that is introduced into, and moves within, a GI tract of a human or animal body. A set of as many as eight nonlinear equations has been developed and applied, relating propagation of a wireless signal between either two, three, or more transmitting antennas located on the PT, to four or more non-coplanar receiving antennas located on a signal receiver appliance worn by the user. The equations are solved exactly, without approximations or iterations, and are applied in several environments: (1) association of a visual image, transmitted by the PT at each of a second sequence of times, with a PT location and PT angular orientation at that time; (2) determination of a position within the body at which a drug or chemical substance or other treatment is to be delivered to a selected portion of the body; (3) monitoring, after delivery, of the effect(s) of administration of the treatment; and (4) determination of one or more positions within the body where provision and examination of a finer-scale image is warranted.

Traditional Tibetan medicine starts to be a very popular complementary medicine in USA and Europe. These pills contain many elements essential for the human body. However, they might also contain heavy metals such as mercury, iron, arsenic, etc. This paper focuses on elemental composition of two Tibetan pills and investigation of forms of iron in them. X-ray fluorescence spectroscopy and neutron activation analysis identified the presence of several heavy metals such as mercury, iron and copper. Mőssbauer spectroscopy revealed the possible presence of α - F e 2 O 3(hematite) and α - F e O O H(goethite) in both of the investigated samples.

Intraductal tubulopapillary neoplasm (ITPN) is a recently recognized rare variant of intraductal neoplasms of the pancreas. Molecular aberrations underlying the neoplasm remain unknown. We investigated somatic mutations in PIK3CA, PTEN, AKT1, KRAS, and BRAF. We also investigated aberrant expressions of phosphorylated AKT, phosphatase and tensin homolog (PTEN), tumor protein 53 (TP53), SMAD4, and CTNNB1 in 11 cases of ITPNs and compared these data with those of 50 cases of intraductal papillary mucinous neoplasm (IPMN), another distinct variant of pancreatic intraductal neoplasms. Mutations in PIK3CA were found in 3 of 11 ITPNs but not in IPMNs (P = 0.005; Fisher exact test). In contrast, mutations in KRAS were found in none of the ITPNs but were found in 26 of the 50 IPMNs (P = 0.001; Fisher exact test). PIK3CA mutations were associated with strong expression of phosphorylated AKT (P AKT was apparent in most ITPNs but only in a few IPMNs (P SMAD4, and CTNNB1 were not statistically different between these neoplasms. Mutations in PIK3CA and the expression of phosphorylated AKT were not associated with age, sex, tissue invasion, and patients' prognosis in ITPNs. These results indicate that activation of the phosphatidylinositol 3-kinase pathway may play a crucial role in ITPNs but not in IPMNs. In contrast, the mutation in KRAS seems to play a major role in IPMNs but not in ITPNs. The activated phosphatidylinositol 3-kinase pathway may be a potential target for molecular diagnosis and therapy of ITPNs.

We consider ultracold neutron (UCN) sources based on a new method of UCN production in superfluid helium ("4He). The PIK reactor is chosen as a perspective example of application of this idea, which consists of installing "4He UCN source in the beam of thermal or cold neutrons and surrounding the source with moderator-reflector, which plays the role of cold neutron (CN) source feeding the UCN source. CN flux in the source can be several times larger than the incident flux, due to multiple neutron reflections from the moderator–reflector. We show that such a source at the PIK reactor would provide an order of magnitude larger density and production rate than an analogous source at the ILL reactor. We estimate parameters of "4He source with solid methane (CH_4) or/and liquid deuterium (D_2) moderator–reflector. We show that such a source with CH_4 moderator–reflector at the PIK reactor would provide the UCN density of ~1·10"5 cm"−"3, and the UCN production rate of ~2·10"7 s"−"1. These values are respectively 1000 and 20 times larger than those for the most intense UCN user source. The UCN density in a source with D_2 moderator-reflector would reach the value of ~2·10"5 cm"−"3, and the UCN production rate would be equal ~8·10"7 s"−"1. Installation of such a source in a beam of CNs would slightly increase the density and production rate.

As abortion is illegal in Nicaragua, postcoital contraception is an important option for preventing pregnancy. Emergency contraceptive pills are available in Nicaraguan pharmacies over the counter, but pharmacy personnel's knowledge and attitudes about this method can affect access. A cross-sectional survey was conducted in Managua, Nicaragua's capital. Interviewers administered a semistructured questionnaire to 93 pharmacy employees to determine their knowledge of and attitudes toward emergency contraceptive pills. Descriptive statistics and cross-tabulations were used to examine responses of and differences between male and female employees. All participants knew about emergency contraceptive pills and reported experience selling them. The majority sold them at least once a week (92%), usually without a prescription (97%). Of participants who were aware that emergency contraceptive pills should be taken only after sexual intercourse, 45% knew that the pills can be taken up to three days afterward; none knew that the pills are effective up to five days afterward. More than one-third of all respondents (39%) thought the pills can induce abortion, and most overestimated contraindications and side effects. Large majorities believed the availability of emergency contraceptive pills discourages use of ongoing methods (75%), encourages sexual risk-taking (82%) and increases transmission of HIV and other STIs (76%). Sixty-three participants (68%) thought emergency contraceptive pills are necessary to reduce unwanted and unplanned pregnancy; 65% were willing to provide them to all women in need, although only 13% would provide them to minors. Managuan pharmacy personnel frequently dispense emergency contraceptive pills, but need additional education to accurately counsel women about the method.

Full Text Available Abstract Background BRAF, KRAS and PIK3CA mutations are frequently found in sporadic colorectal cancer (CRC. In contrast to KRAS and PIK3CA mutations, BRAF mutations are associated with tumours harbouring CpG Island methylation phenotype (CIMP, MLH1 methylation and microsatellite instability (MSI. We aimed at determine the frequency of KRAS, BRAF and PIK3CA mutations in the process of colorectal tumourigenesis using a series of colorectal polyps and carcinomas. In the series of polyps CIMP, MLH1 methylation and MSI were also studied. Methods Mutation analyses were performed by PCR/sequencing. Bisulfite treated DNA was used to study CIMP and MLH1 methylation. MSI was detected by pentaplex PCR and Genescan analysis of quasimonomorphic mononucleotide repeats. Chi Square test and Fisher's Exact test were used to perform association studies. Results KRAS, PIK3CA or BRAF occur in 71% of polyps and were mutually exclusive. KRAS mutations occur in 35% of polyps. PIK3CA was found in one of the polyps. V600E BRAF mutations occur in 29% of cases, all of them classified as serrated adenoma. CIMP phenotype occurred in 25% of the polyps and all were mutated for BRAF. MLH1 methylation was not detected and all the polyps were microsatellite stable. The comparison between the frequency of oncogenic mutations in polyps and CRC (MSI and MSS lead us to demonstrate that KRAS and PIK3CA are likely to precede both types of CRC. BRAF mutations are likely to precede MSI carcinomas since the frequency found in serrated polyps is similar to what is found in MSI CRC (P = 0.9112, but statistically different from what is found in microsatellite stable (MSS tumours (P = 0.0191. Conclusion Our results show that BRAF, KRAS and PIK3CA mutations occur prior to malignant transformation demonstrating that these oncogenic alterations are primary genetic events in colorectal carcinogenesis. Further, we show that BRAF mutations occur in association with CIMP phenotype in colorectal

THE BEHAVIOUR OF FABRICS USED FOR ANTIMIS PRODUCTION TO PILLING

Directory of Open Access Journals (Sweden)

CHIRILĂ Mihai Maxim

2016-05-01

Full Text Available The present study about the behaviour of plain textiles used for the production of antimis (Christian-orthodox liturgical item used in the liturgy to pilling explores the functional classification of different types of antimis as a textile product made out the following different types of fabrics: natural silk, flax, viscose, polyamide 6.6. Pilling is a phenomenon which consists of the formation of small balls made out of fibre congeries on the textile’s surface due to attrition and fatigue. For textiles used as liturgical items, the process of pilling formation includes the following stages: the emergence of the pilling surfaces (the formation of fuzzy, fibre tangle (appearance of small balls, and the detachment of small balls from the fabric’s surface. The analysis method of pilling for liturgical items made out the four types of fabrics mentioned above consists of stereoscopic microscopy techniques and electronic microscopy methods (SEM. The images of textiles samples (yarns and fabrics will be captured using a video microscope. Quantitative tests have been done to determine the metric number and the tex title of the above-mentioned fabrics. The increased resistance of silk to pilling compared to nylon, flax, and viscose can be attributed to the chemical properties of fibres and structural characteristics of silk fabric. The structural compactness of the same fiber mixture of natural silk fabric with bonded fabric will have a higher resistance coefficient to pilling compared to the other mentioned fabrics. Through this, the value of use and durability of the antimis will increase.

To observe the clinical effect of Qilin Pills in the treatment of severe oligozoospermia after microsurgical ejaculatory duct reconstruction for obstructive azoospermia. We retrospectively analyzed 75 cases of obstructive azoospermia treated by ejaculatory duct reconstruction followed by administration of Qilin Pills. The patients were divided into a Qilin group (n=42) and a control group (n=33) postoperatively, treated with Qilin Pills and placebo, respectively. After 3 months of medication, we compared the sperm quality between the two groups of patients. After 3 months' treatment, all the patients experienced remarkable improvement in sperm quality (P0.05). The total effectiveness rate was higher in the Qilin group than in the controls (88.1% vs 72.7%), but with no significant difference between the two groups (P>0.05). Qilin Pills are fairly effective in improving the quantity of sperm in obstructive azoospermia patients after ejaculatory duct reconstruction.

Happy-People-Pills for All

It is argued that we have a moral duty to create, and make available, advanced pharmacological agents to boost the happiness of those in the normal, i.e., the non-depressed, range of happiness. Happiness, conceived as a propensity to positive moods, is a quantitative trait with a sizeable genetic component. One means to boost the happiness of those in the normal range is to test the efficacy of antidepressants for enhancement. A second possibility is to model new pharmacologicals based on the genetics of the happiest amongst us, that is, the hyperthymic. The suggestion, in other words, is to “reverse engineer” the hyperthymic: to investigate what makes the hyperthymic genetically and physiologically different and then put what they have into pill form. To the ‘Brave New World’ objection, that there is more to wellbeing than happiness and that taking happy-people-pills will require the sacrifice of these other aspects of wellbeing, it is countered that contemporary social science research supports the view that happiness promotes achievement in the ‘higher’ endeavors of humanity, including work, love and virtue. In other words, happiness promotes acquisition of traits valued by perfectionists. Those born with genes for hyperthymia, on average, tend to be doubly blessed: they are happier and achieve more than the rest of the population. Happy-people-pills are a means to allow everyone else to share in this good

SAR405, a PIK3C3/Vps34 inhibitor that prevents autophagy and synergizes with MTOR inhibition in tumor cells.

Pasquier, Benoit

2015-04-03

Autophagy plays an important role in cancer and it has been suggested that it functions not only as a tumor suppressor pathway to prevent tumor initiation, but also as a prosurvival pathway that helps tumor cells endure metabolic stress and resist death triggered by chemotherapeutic agents. We recently described the discovery of inhibitors of PIK3C3/Vps34 (phosphatidylinositol 3-kinase, catalytic subunit type 3), the lipid kinase component of the class III phosphatidylinositol 3-kinase (PtdIns3K). This PtdIns3K isoform has attracted significant attention in recent years because of its role in autophagy. Following chemical optimization we identified SAR405, a low molecular mass kinase inhibitor of PIK3C3, highly potent and selective with regard to other lipid and protein kinases. We demonstrated that inhibiting the catalytic activity of PIK3C3 disrupts vesicle trafficking from late endosomes to lysosomes. SAR405 treatment also inhibits autophagy induced either by starvation or by MTOR (mechanistic target of rapamycin) inhibition. Finally our results show that combining SAR405 with everolimus, the FDA-approved MTOR inhibitor, results in a significant synergy on the reduction of cell proliferation using renal tumor cells. This result indicates a potential therapeutic application for PIK3C3 inhibitors in cancer.

To observe the therapeutic effect of Qilin Pills combined with clomiphene on idiopathic oligoasthenospermia. We randomly assigned 300 patients with idiopathic oligoasthenospermia to a trial (n = 156) and a control group (n = 144) to be treated with Qilin Pills (6 g, tid) combined with clomiphene (50 mg, qd) and clomiphene alone (50 mg, qd), respectively, both for a course of 12 weeks. Before and after 4, 8, and 12 weeks of medication, we determined sperm concentration, the percentages of grade a and grade a + b sperm, sperm motility, and the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (T), followed by evaluation of the clinical efficacy of Qilin Pills with the pregnancy rate in the patients' spouses as the secondaty therapeutic indexes. Compared with the baseline, both groups of patients showed remarkably improved semen parameters and hormone levels after treatment (all P 0.05). No obvious adverse reactions were observed. Qilin Pills combined with clomiphene can evidently improve the seminal quality and hormone level of oligoasthenospermia patients with no obvious adverse events. However, its long-term efficacy and tolerance deserve further clinical investigation.

The Dutch College of General Practitioners' (NHG) guideline 'Sleep problems and sleeping pills' provides recommendations for the diagnosis and treatment of the most prevalent sleep problems and for the management of chronic users of sleeping pills. The preferred approach for sleeplessness is not to prescribe medication but to give information and behavioural advice. Practice assistants of the Dutch Association of Mental Health and Addiction Care are also expected to be able to undertake this management. The GP may consider prescribing sleeping pills for a short period only in cases of severe insomnia with considerable distress. Chronic users of sleeping pills should be advised by the GP to stop using them or to reduce the dose gradually (controlled dose reduction). The GP may refer patients with suspected obstructive sleep apnoea (OSA) to a pulmonary or ear, nose and throat specialist or neurologist for further diagnosis depending on the regional arrangements. The GP may then consider the cardiovascular risk factors commonly present with OSA. In patients with restless legs syndrome (RLS) who continue to experience major distress despite being given advice without the prescription of medication, the GP may consider prescribing a dopamine agonist.

The PTEN tumour suppressor gene and PIK3CA proto-oncogene encode proteins which contribute to regulation and propagation of signal transduction through the PI3K/AKT signalling pathway. This study investigates the prevalence of loss of PTEN expression and mutations in both PTEN and PIK3CA in colorectal cancers (CRC) and their associations with tumour clinicopathological features, lifestyle factors and dietary consumptions. 186 adenocarcinomas and 16 adenomas from the EPIC Norfolk study were tested for PTEN and PIK3CA mutations by DNA sequencing and PTEN expression changes by immunohistochemistry. Dietary and lifestyle data were collected prospectively using seven day food diaries and lifestyle questionnaires. Mutations in exons 7 and 8 of PTEN were observed in 2.2% of CRC and PTEN loss of expression was identified in 34.9% CRC. Negative PTEN expression was associated with lower blood low-density lipoprotein concentrations (p = 0.05). PIK3CA mutations were observed in 7% of cancers and were more frequent in CRCs in females (p = 0.04). Analysis of dietary intakes demonstrated no link between PTEN expression status and any specific dietary factor. PTEN expression negative, proximal CRC were of more advanced Dukes' stage (p = 0.02) and poor differentiation (p < 0.01). Testing of the prevalence of PIK3CA mutations and loss of PTEN expression demonstrated that these two events were independent (p = 0.55). These data demonstrated the frequent occurrence (34.9%) of PTEN loss of expression in colorectal cancers, for which gene mutations do not appear to be the main cause. Furthermore, dietary factors are not associated with loss of PTEN expression. PTEN expression negative CRC were not homogenous, as proximal cancers were associated with a more advanced Dukes' stage and poor differentiation, whereas distal cancers were associated with earlier Dukes' stage

Full Text Available Abstract Background Recent studies have shown that the phosphatidylinositol 3-kinase (PI3K signaling pathway is important regulator of many cellular events, including apoptosis, proliferation and motility. PI3K pathway alterations (PIK3CA gene mutations and/or amplification have been observed in various human tumours. In the majority of diagnosed cases, mutations are localized in one of the three "hot spots" in the gene, responsible for coding catalytic subunit α of class I PI3K (PIK3CA. Mutations and amplification of PIK3CA gene are characteristic for thyroid cancer, as well. Methods The aim of our study was to examine a gene expression level of PIK3CA in fine-needle aspiration biopsy (FNAB thyroid specimens in two types of thyroid lesions, papillary thyroid carcinoma (PTC and non-toxic goitre (NTG. Following conventional cytological examination, 42 thyroid FNAB specimens, received from patients with PTC (n = 20 and NTG (n = 22, were quantitatively evaluated regarding PIK3CA expression level by real-time PCR in the ABI PRISM® 7500 Sequence Detection System. Results Significantly higher expression level (RQ of PIK3CA in PTC group has been noted in comparison with NTG group (p Conclusion These observations may suggest role of PIK3CA alterations in PTC carcinogenesis.

Pilling is a phenomenon that has a long cause trouble in textile industry. It is the formation of pills or knops on the surface of woven or knitted fabrics caused by friction and abrasion. If fabric has a pronounced tendency to pilling, their appearances suffer severely after a short period of use. The pilling of fabrics is a serious problem for the apparel industry. The use of anti pilling finishes is one of the best techniques to control the pilling of the fabric. In this method fabric is treated with special anti pilling agents to prevent pilling that promote adhesion of the fibres in the yarn or the fabric. This paper endeavors to optimize the application of different anti pilling agents at different concentration and pH levels on the Tensile Strength of P/C fabric for best results. The results exposed that different anti pilling finishes have significant effects on the Tensile Strength of fabric at different concentration level however different pH levels have no considerable effects.

The current national opioid epidemic is a public health emergency. We have identified an outbreak of exaggerated opioid toxicity caused by fentanyl adulterated tablets purchased on the street as hydrocodone/acetaminophen. Over an 8-day period in late March 2016, a total of 18 patients presented to our institution with exaggerated opioid toxicity. The patients provided a similar history: ingesting their "normal dose" of hydrocodone/acetaminophen tablets but with more pronounced symptoms. Toxicology testing and analysis was performed on serum, urine, and surrendered pills. One of the 18 patients died in hospital. Five patients underwent cardiopulmonary resuscitation, one required extracorporeal life support, three required intubation, and two received bag-valve-mask ventilation. One patient had recurrence of toxicity after 8 hours after naloxone discontinuation. Seventeen of 18 patients required boluses of naloxone, and four required prolonged naloxone infusions (26-39 hours). All 18 patients tested positive for fentanyl in the serum. Quantitative assays conducted in 13 of the sera revealed fentanyl concentrations of 7.9 to 162 ng/mL (mean = 52.9 ng/mL). Pill analysis revealed fentanyl amounts of 600-6,900 μg/pill. The pills are virtually indistinguishable from authentic hydrocodone/acetaminophen tablets and are similar in weight. To date, our county has reported 56 cases of fentanyl opioid toxicity, with 15 fatalities. In our institution, the outbreak has stressed the capabilities and resources of the emergency department and intensive care units. A serious outbreak of exaggerated opioid toxicity caused by fentanyl-adulterated tablets purchased on the street as hydrocodone/acetaminophen is under way in California. These patients required higher dosing and prolonged infusions of naloxone. Additionally, observation periods off naloxone were extended due to delayed, recurrent toxicity. The outbreak has serious ramifications for public health and safety, law

Bilateral perisylvian polymicrogyria (BPP), the most common form of regional polymicrogyria, causes the congenital bilateral perisylvian syndrome, featuring oromotor dysfunction, cognitive impairment, and epilepsy. The causes of BPP are heterogeneous, but only a few genetic causes have been reported. The aim of this study was to identify additional genetic causes of BPP and characterise their frequency in this population. Children (aged ≤18 years) with polymicrogyria were enrolled into our research programme from July, 1980, to October, 2015, at two centres (Florence, Italy, and Seattle, WA, USA). We obtained samples (blood and saliva) throughout this period at both centres and did whole-exome sequencing on DNA from eight trios (two parents and one affected child) with BPP in 2014. After the identification of mosaic PIK3R2 mutations in two of these eight children, we performed targeted screening of PIK3R2 by two methods in a cohort of 118 children with BPP. First, we performed targeted sequencing of the entire PIK3R2 gene by single molecule molecular inversion probes (smMIPs) on 38 patients with BPP with normal to large head size. Second, we did amplicon sequencing of the recurrent PIK3R2 mutation (Gly373Arg) in 80 children with various types of polymicrogyria including BPP. One additional patient had clinical whole-exome sequencing done independently, and was included in this study because of the phenotypic similarity to our cohort. We identified a mosaic mutation (Gly373Arg) in a regulatory subunit of the PI3K-AKT-mTOR pathway, PIK3R2, in two children with BPP. Of the 38 patients with BPP and normal to large head size who underwent targeted next-generation sequencing by smMIPs, we identified constitutional and mosaic PIK3R2 mutations in 17 additional children. In parallel, one patient had the recurrent PIK3R2 mutation identified by clinical whole-exome sequencing. Seven of these 20 patients had BPP alone, and 13 had BPP in association with features of the

This study aimed to investigate patterns and context of use of BZP-party pills, function of use, and positive and negative effects experienced by a sample of New Zealand young people who had used the products. A qualitative study comprised of semi-structured interviews and group discussions. The sample included 58 young people aged 17-23 years who had used BZP-party pills in the previous 12 months. Young people were using these substances in a range of settings--primarily during weekend social occasions--particularly as part of the dance party culture. They were mostly used for their stimulant properties and to enhance socialisation, and were often taken in combination with other legal and illicit drugs. Young people had suffered a range of physical and emotional negative effects, although none of these was reported as being life-threatening or long-term. Many participants had reduced the frequency with which they used BZP-party pills due to adverse effects. Potentially risky behaviours identified included taking large doses, mixing BZP-party pills with alcohol and other substances, and driving whilst under the influence of BZP-party pills. Findings suggest that young people in this study were not suffering excessive or dangerous adverse effects. However, potentially risky use of these products raises the issue of the need for developing harm reduction interventions.

To study the effect and probable mechanism of Qishen Yiqi Pills on adriamycin (ADR)-induced cardiomyopathy in mice. Sixty-four mice were randomly divided into (1) the ADR group: saline (1 mL/100 g) administered every day by intragavage, ADR (4 mg·kg(-1)) administered to each mouse by intraperitoneal injection twice a week for four weeks; (2) the ADR + Qishen Yiqi Pills I group: ADR (4 mg·kg(-1)) administered to each mouse by intraperitoneal injection twice a week for four weeks, and at the beginning of the third week Qishen Yiqi Pills (3.5 mg/100 g) administered by intragavage every day for four weeks; (3) the ADR + Qishen Yiqi Pills II group: ADR (4 mg·kg(-1)) administered to each mouse by intraperitoneal injection twice a week for four weeks, and at the same time Qishen Yiqi Pills (3.5 mg/100 g) administered by intragavage every day for four weeks; (4) the control group: saline (1 mL/100 g) administered every day by intragavage, saline (1 mL·kg(-1)) administered to each mouse by intraperitoneal injection twice a week for four weeks. Six weeks later, cardiac function, myocardial pathology, and expression of Bcl-2 and Bax were evaluated. 1. The left ventricular diastolic diameter and the left ventricular systolic diameter were significantly increased (P Pills I group and the ADR + Qishen Yiqi Pills II group improved. 2. Myocardial morphologic observation showed that the myocardial fibers were disordered, there was cell edema, and gap widening in the ADR group. The degree of myocardial cell injury was reduced in the ADR + Qishen Yiqi Pills I group and ADR + Qishen Yiqi Pills II group compared with the ADR group. 3. The expression of Bax in the ADR group was significantly up-regulated, and the expression of Bcl-2 was significantly downregulated in the ADR group compared with the ADR + Qishen Yiqi Pills I group, the ADR + Qishen Yiqi Pills II group, and the control group (P Pills can effectively improve the cardiac function of ADR-induced cardiomyopathy, and the

Full Text Available Mutant cancer subpopulations have the potential to derail durable patient responses to molecularly targeted cancer therapeutics, yet the prevalence and size of such subpopulations are largely unexplored. We employed the sensitive and quantitative Allele-specific Competitive Blocker PCR approach to characterize mutant cancer subpopulations in ductal carcinomas (DCs, examining five specific hotspot point mutations (PIK3CA H1047R, KRAS G12D, KRAS G12V, HRAS G12D, and BRAF V600E. As an approach to aid interpretation of the DC results, the mutations were also quantified in normal breast tissue. Overall, the mutations were prevalent in normal breast and DCs, with 9/9 DCs having measureable levels of at least three of the five mutations. HRAS G12D was significantly increased in DCs as compared to normal breast. The most frequent point mutation reported in DC by DNA sequencing, PIK3CA H1047R, was detected in all normal breast tissue and DC samples and was present at remarkably high levels (mutant fractions of 1.1 × 10−3 to 4.6 × 10−2 in 4/10 normal breast samples. In normal breast tissue samples, PIK3CA mutation levels were positively correlated with age. However, the PIK3CA H1047R mutant fraction distributions for normal breast tissues and DCs were similar. The results suggest PIK3CA H1047R mutant cells have a selective advantage in breast, contribute to breast cancer susceptibility, and drive tumor progression during breast carcinogenesis, even when present as only a subpopulation of tumor cells.

Methods of Study Selection This study included data from 136 studies which followed a defined population of women treated one time with emergency contraceptive pills (either mifepristone or levonorgestrel), and in which the number and location of pregnancies were ascertained. Results Data from each article were abstracted independently by two reviewers. In the studies of mifepristone, 3 out of 494 (0.6%) pregnancies were ectopic; in the levonorgestrel studies, 3 out of 307 (1%) were ectopic. Conclusion The rate of ectopic pregnancy when treatment with emergency contraceptive pills fails does not exceed the rate observed in the general population. Since emergency contraceptive pills are effective in lowering the risk of pregnancy, their use should reduce the chance that an act of intercourse will result in ectopic pregnancy. PMID:20502299

The performance of an adiabatic demagnetization refrigerator (ADR) is critically dependent on the design and construction of the salt pills that produce cooling. In most cases, the primary goal is to obtain the largest cooling capacity at the low temperature end of the operating range. The realizable cooling capacity depends on a number of factors, including refrigerant mass, and how efficiently it absorbs heat from the various instrument loads. The design and optimization of "salt pills" for ADR systems depend not only on the mechanical, chemical and thermal properties of the refrigerant, but also on the range of heat fluxes that the salt pill must accommodate. Despite the fairly wide variety of refrigerants available, those used at very low temperature tend to be hydrated salts that require a dedicated thermal bus and must be hermetically sealed, while those used at higher temperature - greater than about 0.5 K - tend to be single-­- or poly-­-crystals that have much simpler requirements for thermal and mechanical packaging. This paper presents a summary of strategies and techniques for designing, optimizing and fabricating salt pills for both low-­- and mid-­-temperature applications.

In the past 16 years, the number of prescription opioids sold in the United States, as well as deaths from prescription opioids, has nearly quadrupled. However, the overall amount of pain reported by patients has not changed significantly. Specific information about opioid prescriptions in the perioperative period is lacking. Of the studies that have been published, investigators have shown that the majority of patients have unused postoperative opioid pills. Moreover, patients appear to lack information about disposal of unused opioid pills. To compare the number of pills prescribed versus the numbers left unused after outpatient shoulder surgeries at an orthopaedic surgery institution. Case series; Level of evidence, 4. In this prospective, observational study, 100 patients (age >18 years) undergoing outpatient shoulder surgery (rotator cuff repair, labral repair, stabilization/Bankart repair, debridement) were enrolled. Follow-ups were conducted via surveys on postoperative days (PODs) 7, 14, 28, and 90. The primary outcome was the number of unused pills from the originally prescribed medication. For all procedure types, the median (Q1, Q3) number of prescribed pills was 60 (40, 80). On POD 90, patients reported a median (Q1, Q3) of 13 (0, 32) unused pills; patients who underwent rotator cuff repairs had the lowest number of pills remaining (median [Q1, Q3], 0 [0, 16]), whereas patients who had stabilization/Bankart repairs had the highest number of unused pills (median [Q1, Q3], 37 [29, 50]). Patient satisfaction with pain management ranged from an average of 70% to 90%. Only 25 patients received instructions or education about opioid disposal. Most outpatient shoulder surgery patients who underwent certain operations were prescribed more opioid analgesics than they consumed. Patient education regarding the disposal of opioids was lacking.

Bringing smart pills to market: FDA regulation of ingestible drug/device combination products.

Imagine a pill that, after you swallow it, can track its position in your body. Or imagine a pill that can transmit a message to a doctor to tell him that you have taken your bitter medicine. Pills like this already exist. These so-called smart pills are an emerging type of medical therapy. However, this nascent technology has yet to reach the market and developers of these novel therapies face significant regulatory challenges. This article predicts how the Food and Drug Administration will regulate smart pills and shows how the current regulatory regime is inadequate. The article then proposes modifying the current regulatory regime to encourage development of smart pills and other innovative combination products by: (1) regulating combination products based on their "novel mode of action" rather than their "primary mode of action," (2) creating a marketing approval pathway specifically for combination products, and (3) eliminating regulations that require sponsors to get marketing approval from multiple centers within FDA and providing regulatory guidance specifically for ingestible drug/device combination products.

Social constructions of the male contraception pill: When are we going to break the vicious circle?

Dismore, Lorelle; Van Wersch, Anna; Swainston, Katherine

2016-05-01

Social constructions of men towards the availability of a male hormonal contraceptive, the 'male pill', were explored. A qualitative approach applying semi-structured interviews and scenarios with 22 men (mean age 35 years) from the North East of England revealed two core constructs and six sub-constructs using a Thematic-Construct Analysis in line with the method of Toerien and Wilkinson and Clarke and Kitzinger. Verbal accounts were inductively used to balance the deductively created two core constructs 'Constructing the male pill norm: dominant system of sensemaking' and 'Living by the male pill norm' to represent a normative framework within a changing ideology of shared responsibility in contraceptive choice. Constructing the male pill norm was divided into two sub-constructs: 'Male pill: we are going to join the women and become responsible - too!' and 'Male pill: you look so girly - what are they going to think of me?' The 'Living by the male pill norm' was further divided into four sub-constructs 'Male pill - thank you for giving me promises not to have to become a dad as yet!'; 'Male pill: thank you for the idea of fun - sorry about my morals!'; 'Male pill: in stable relations - yes, I would have you now - sorry, I am too late!' and 'Male pill, we love you - but we are too anxious - we are not ready as yet!' From this male discourse, it is clear that discussions over the male pill follow the line of a vicious circle. In order to establish long-term side effects, Phase IV studies are necessary, and these cannot commence without the male hormonal contraception being a marketable product. So, unless this circle gets broken by some brave men, the male pill will remain a virtual rotating idea for a long time. © The Author(s) 2014.

2012-01-01

Core temperature measurement with an ingestible telemetry pill has been scarcely investigated during extreme rates of temperature change, induced by short high-intensity exercise in the heat. Therefore, nine participants performed a protocol of rest, (sub)maximal cycling and recovery at 30 °C. The pill temperature (T pill ) was compared with the rectal temperature (T re ) and esophageal temperature (T es ). T pill corresponded well to T re during the entire trial, but deviated considerably from T es during the exercise and recovery periods. During maximal exercise, the average ΔT pill −T re and ΔT pill −T es were 0.13 ± 0.26 and −0.57 ± 0.53 °C, respectively. The response time from the start of exercise, the rate of change during exercise and the peak temperature were similar for T pill and T re. T es responded 5 min earlier, increased more than twice as fast and its peak value was 0.42 ± 0.46 °C higher than T pill . In conclusion, also during considerable temperature changes at a very high rate, T pill is still a representative of T re . The extent of the deviation in the pattern and peak values between T pill and T es (up to >1 °C) strengthens the assumption that T pill is unsuited to evaluate central blood temperature when body temperatures change rapidly.

SUMMARY Background Bilateral perisylvian polymicrogyria (BPP), the most common form of regional polymicrogyria, causes the congenital bilateral perisylvian syndrome, featuring oromotor dysfunction, cognitive impairment and epilepsy. BPP is etiologically heterogeneous, but only a few genetic causes have been reported. The aim of this study was to identify additional genetic etiologies of BPP and delineate their frequency in this patient population. Methods We performed child-parent (trio)-based whole exome sequencing (WES) on eight children with BPP. Following the identification of mosaic PIK3R2 mutations in two of these eight children, we performed targeted screening of PIK3R2 in a cohort of 118 children with BPP who were ascertained from 1980 until 2015 using two methods. First, we performed targeted sequencing of the entire PIK3R2 gene by single molecule molecular inversion probes (smMIPs) on 38 patients with BPP with normal-large head size. Second, we performed amplicon sequencing of the recurrent PIK3R2 mutation (p.Gly373Arg) on 80 children with various types of polymicrogyria including BPP. One additional patient underwent clinical WES independently, and was included in this study given the phenotypic similarity to our cohort. All patients included in this study were children (BPP. Of the 38 patients with BPP and normal-large head size who underwent targeted next generation sequencing by smMIPs, we identified constitutional and mosaic PIK3R2 mutations in 17 additional children. In parallel, one patient was found to have the recurrent PIK3R2 mutation by clinical WES. Seven patients had BPP alone, and 13 had BPP in association with features of the megalencephaly-polymicrogyria-polydactyly-hydrocephalus syndrome (MPPH). Nineteen patients had the same mutation (Gly373Arg), and one had a nearby missense mutation (p.Lys376Glu). Across the entire cohort, mutations were constitutional in 12 and mosaic in eight patients. Among mosaic patients, we observed substantial

This report describes the 100 MW research reactor PIK which is now under construction. The thermal neutron flux in the heavy water reflector exceeds 10{sup 15} cm{sup -2}s{sup -1}; in the light water trap, it is about 4{center_dot}10{sup 15} cm{sup -2}s{sup -1}. The replaceable core vessel allows to vary the parameters of the core over a wide range. The reactor provides sources of hot, cold and ultracold neutrons for 10 horizontal, 6 inclined neutron beams, and 8 neutron guides. At the ends of the beam tubes, the neutron flux is 10{sup 10} - 10{sup 11} cm{sup -2}s{sup -1}. The flux of the long wave neutrons exceeds 10{sup 9} cm{sup -2}s{sup -1}. To ensure precise measurements, the experimental hall is protected against vibrations. The project meets all modern safety requirements. The calculated parameters of the reactor were verified using a full-scale mock-up. Seventy percent of the reactor construction and installation were completed in the beginning of 1992. (author)

FEM-PrEP was unable to determine whether once-daily, oral emtricitabine/tenofovir disoproxil fumarate reduces the risk of HIV acquisition among women because of low adherence. Self-reported adherence was high, and pill-count data suggested good adherence. Yet, drug concentrations revealed limited pill use. We conducted a follow-up study with former participants in Bondo, Kenya, and Pretoria, South Africa, to understand factors that had influenced overreporting of adherence and to learn the whereabouts of unused pills. Qualitative, semistructured interviews were conducted with 88 participants, and quantitative, audio computer-assisted self-interviews were conducted with 224 participants. We used thematic analysis and descriptive statistics to analyze the qualitative and quantitative data, respectively. In audio computer-assisted self-interviews, 31% (n = 70) said they had overreported adherence; the main reason was the belief that nonadherence would result in trial termination (69%, n = 48). A considerable percentage (35%, n = 78) acknowledged discarding unused pills. Few acknowledged giving their pills to someone else (4%, n = 10), and even fewer acknowledged giving them to someone with HIV (2%, n = 5). Many participants in the semistructured interviews said other participants had counted and removed pills from their bottles to appear adherent. Despite repeated messages that nonadherence would not upset staff, participants acknowledged several perceived negative consequences of reporting nonadherence, which made it difficult to report accurately. Uneasiness continued in the follow-up study, as many said they had not overreported during the trial. Efforts to improve self-reported measures should include identifying alternative methods for creating supportive environments that allow participants to feel comfortable reporting actual adherence.

The atypical protein kinase C isoform PRKC iota (PRKCI) plays a key role in cell proliferation, differentiation, and carcinogenesis, and it has been shown to be a human oncogene. Here, we show that PRKCI overexpression in U2OS cells impaired functional autophagy in normal or cell stress conditions, as characterized by decreased levels of light chain 3B-II protein (LC3B-II) and weakened degradation of endogenous and exogenous autophagic substrates. Conversely, PRKCI knockdown by small interference RNA resulted in opposite effects. Additionally, we identified two novel PRKCI mutants, PRKCI{sup L485M} and PRKCI{sup P560R}, which induced autophagy and exhibited dominant negative effects. Further studies indicated that PRKCI knockdown–mediated autophagy was associated with the inactivation of phosphatidylinositol 3-kinase alpha/AKT–mammalian target of rapamycin (PIK3CA/AKT–MTOR) signaling. These data underscore the importance of PRKCI in the regulation of autophagy. Moreover, the finding may be useful in treating PRKCI-overexpressing carcinomas that are characterized by increased levels of autophagy. - Highlights: • The atypical protein kinase C iota isoform (PRKCI) is a human oncogene. • PRKCI overexpression impairs functional autophagy in U2OS cells. • It reduces LC3B-II levels and weakens SQSTM1 and polyQ80 aggregate degradation. • PRKCI knockdown has the opposite effect. • The effect of PRKCI knockdown is related to PIK3CA/AKT–MTOR signaling inactivation.

Application of microscopic spectroscopy in quality control of Niuhuang Qingxin pills was discussed. First, microscopic characteristics specified by the statutory standard of Niuhuang Qingxin pills were summarized. Then new identification method was established for Dioscoreae Rhizoma, Saigae Tataricae Cornu, Cinnamomi Cortex and Saposhnikoviae Radix. Finally, microscopic spectroscopy was used for test of Dioscoreae Rhizoma's adulterant Dioscoreae Fordii Rhizoma.It was the first time for this technology being applied in adulteration test of Chinese patent medicine.The results showed that Saigae Tataricae Cornu was not detected in 2 batches of Niuhuang Qingxin pills from 1 manufacturer while Dioscoreae Fordii Rhizoma was detected in 3 batches of samples from 2 manufacturers. The proposed methods were accurate, simple, rapid, objective and economic, which offered a more comprehensive approach for quality control of Niuhuang Qingxin pills. It was indicated that conventional technology such as microscopic spectroscopy could play an important role in identification of traditional Chinese medicine whose index ingredient was deficient or tiny.

The Potsdam Parallel Ice Sheet Model (PISM-PIK) - Part 1: Model description

Winkelmann, R.; Martin, M. A.; Haseloff, M.; Albrecht, T.; Bueler, E.; Khroulev, C.; Levermann, A.

2011-09-01

We present the Potsdam Parallel Ice Sheet Model (PISM-PIK), developed at the Potsdam Institute for Climate Impact Research to be used for simulations of large-scale ice sheet-shelf systems. It is derived from the Parallel Ice Sheet Model (Bueler and Brown, 2009). Velocities are calculated by superposition of two shallow stress balance approximations within the entire ice covered region: the shallow ice approximation (SIA) is dominant in grounded regions and accounts for shear deformation parallel to the geoid. The plug-flow type shallow shelf approximation (SSA) dominates the velocity field in ice shelf regions and serves as a basal sliding velocity in grounded regions. Ice streams can be identified diagnostically as regions with a significant contribution of membrane stresses to the local momentum balance. All lateral boundaries in PISM-PIK are free to evolve, including the grounding line and ice fronts. Ice shelf margins in particular are modeled using Neumann boundary conditions for the SSA equations, reflecting a hydrostatic stress imbalance along the vertical calving face. The ice front position is modeled using a subgrid-scale representation of calving front motion (Albrecht et al., 2011) and a physically-motivated calving law based on horizontal spreading rates. The model is tested in experiments from the Marine Ice Sheet Model Intercomparison Project (MISMIP). A dynamic equilibrium simulation of Antarctica under present-day conditions is presented in Martin et al. (2011).

Ernst Julius Öpik's (1916) note on the theory of explosion cratering on the Moon's surface—The complex case of a long-overlooked benchmark paper

High-velocity impact as a common phenomenon in planetary evolution was ignored until well into the twentieth century, mostly because of inadequate understanding of cratering processes. An eight-page note, published in Russian by the young Ernst Julius Öpik, a great Estonian astronomer, was among the key selenological papers, but due to the language barrier, it was barely known and mostly incorrectly cited. This particular paper is here intended to serve as an explanatory supplement to an English translation of Öpik's article, but also to document an early stage in our understanding of cratering. First, we outline the historical-biographical background of this benchmark paper, and second, a comprehensive discussion of its merits is presented, from past and present perspectives alike. In his theoretical research, Öpik analyzed the explosive formation of craters numerically, albeit in a very simple way. For the first time, he approximated relationships among minimal meteorite size, impact energy, and crater diameter; this scaling focused solely on the gravitational energy of excavating the crater (a "useful" working approach). This initial physical model, with a rational mechanical basis, was developed in a series of papers up to 1961. Öpik should certainly be viewed as the founder of the numerical simulation approach in planetary sciences. In addition, the present note also briefly describes Nikolai A. Morozov as a remarkable man, a forgotten Russian scientist and, surprisingly, the true initiator of Öpik's explosive impact theory. In fact, already between 1909 and 1911, Morozov probably was the first to consider conclusively that explosion craters would be circular, bowl-shaped depressions even when formed under different impact angles.

Clinics often encounter neurologically intact patients who are unable to swallow pills. All of the interventions published previously have used traditional behavioural techniques, which are time consuming and often not helpful. To determine whether children who had never been able to swallow a whole pill could become successful as a result of an intervention based on head posture. A novel intervention was developed based on published research showing that changing head position alters swallowing dynamics. The method was developed in two studies of 240 adults and children, pilot tested in a study of 108 university students with very mild pill-swallowing discomfort, and then evaluated in a study of 41 children who had never successfully swallowed a pill in spite of much instruction and coaxing. Children were recruited from a tertiary paediatric hospital: 34 were clinic patients, four were their siblings or friends, and three were children of hospital staff. The primary intervention involved teaching five head positions (centre, up, down, left and right) followed by a two-week period of daily practice. EIGHT CHILDREN (ALL CLINIC REFERRALS) WITHDREW WITHOUT PRACTICING: four were too ill to practice (primarily due to sedation or nausea) and four simply refused to do the homework practice. All 33 of the children who were able and willing to practice daily were successful. Practice with head posture variations was successful in treating pill-swallowing difficulties in all 33 children who practiced for 14 days.

To improve our understanding of the pharmacology of 'ecstasy' in recreational environments; in particular, to describe the composition of ecstasy pills, patterns of ecstasy use and the relationship between dose of 3,4-methylendioxymethamphetamine (MDMA) and resulting plasma concentrations. A naturalistic observational study of 56 experienced 'ecstasy' users in recreational settings in Australia. Drug use patterns (number of pills consumed, other drugs consumed). drug content of pills and resultant plasma concentrations of MDMA and related drugs were assessed by gas chromatography/mass spectrometry (GC/MS). Ecstasy pills generally contained MDMA, but this was often combined with other drugs such as 3,4-ethylendioxyethylamphetamine (MDEA) and methamphetamine. The dose of MDMA per pill ranged from 0 to 245 mg and users consumed from one-half to five pills, with the total dose consumed ranging up to 280 mg. Plasma concentrations of MDMA increased with number of pills consumed and cumulative MDMA dose. Use of larger numbers of pills was associated with extended exposure to the drug. MDMA is the major active drug in ecstasy pills, but there is a high degree of variation in doses. Use of multiple pills over the course of one session is common and results in a sustained increase in MDMA plasma concentrations over a number of hours. This is likely to lead to a much greater exposure of the brain to MDMA than would be predicted from controlled single-dose pharmacokinetic studies. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

Pill organizers and pill cutters: risks and limitations.

Science.gov (United States)

Borja-Oliveira, Caroline Ribeiro de

2013-02-01

In this essay, based on documental analysis, the limitations associated with the use of pill organizers and cutters are discussed and analyzed as a matter of public health. The use of the organizers for storing and carrying tablets and capsules exposes these medications to environmental factors from which their original packaging protected them, compromising their stability and safeness. Cutters also pose the additional risk of causing loss of efficacy, adverse reactions and overdose. On the other hand, the user carrying their own medication reflects the balance between autonomy and self-care, and splitting is sometimes required to comply with certain regimens. It can be concluded that healthcare professionals should observe and guide patients and caregivers in order to avoid risks.

1999-01-01

For reactor 'Pik' (that is being built in St. Petersburg Institute of Nuclear Physics) there was designed a universal two shoulder mass-spectrometer for non-decelerated fission products (FP) of nuclei. The spectrometer helps to obtain different values of linear magnification, dispersion, aberration coefficients and transmission without making structural changes in the device. To separate FP for one shoulder of spectrometer we chose ion-optical scheme (IOS) consisting of three electrostatic analyzers and three-sectional magnet 'JOSEF' that had high dispersion by masses at small deflection radius. IOS calculations of mass-spectrometer were performed with the help of program TRANSVOL (transfer of phase volume) designed basing on TRIO program. The program allows calculating of complete IOS transmission with taking into account elements aperture and beam officering

To improve bioavailability of pueraria flavones (PF), a self-microemulsifying drug delivery system (SMEDDS) dropping pills composed of PF, Crodamol GTCC, Maisine 35-1, Cremophor RH 40, 1,2-propylene glycol and polyethylene glycol 6000 (PEG6000) was developed. Particle size, zeta potential, morphology and in vitro drug release were investigated, respectively. Pharmacokinetics, bioavailability of PF-SMEDDS dropping pills and commercial Yufengningxin dropping pills were also evaluated and compared in rats. Puerarin treated as the representative component of PF was analyzed. Dynamic light scattering showed the ability of PF-SMEDDS dropping pills to form a nanoemulsion droplet size in aqueous media. The type of media showed no significant effects on the release rate of PF. PF-SMEDDS dropping pills were able to improve the in vitro release rate of PF, and the in vitro release of these dropping pills was significantly faster than that of Yufengningxin dropping pills. There was a dramatic difference between the mean value of t1/2, peak concentration (Cmax), the area of concentration-time curve from 0 to 6 h (AUC0-6 h) of PF-SMEDDS dropping pills and that of commercial Yufengningxin dropping pills. A pharmacokinetic study showed that the bioavailability of PF was greatly enhanced by PF-SMEDDS dropping pills. The value of Cmax and relative bioavailability of PF-SMEDDS dropping pills were dramatically improved by an average of 1.69- and 2.36-fold compared with that of Yufengningxin dropping pills after gavage administration, respectively. It was concluded that bioavailability of PF was greatly improved and that PF-SMEDDS dropping pills might be an encouraging strategy to enhance the oral bioavailability of PF.

The PIK reactor is designed for physical research with neutron beams and sample irradiation. In the central trap the thermal neutrons flux is 4x10 15 n/cm 2 s. The reactor power is 100 MW, the thermal neutron flux in the reflector at the maximum of distribution is 1x10 15 n/cm 2 s. The core with a high uranium concentration of 600 g/l is light water-cooled, heavy water being used in the reflector. The Chernobyl disaster happened at the time of equipment installation at the PIK. The code revision, a change of the authors ideas about the safety, and a change of public attitude towards nuclear installations resulted in a stopping of construction and project revision. Reconstruction project has led to a change of all safety systems and involved in various degrees all essential reactor systems. The construction is presently resumed in spite of economic difficulties in Russia. The reactor was inspected by experts from a number of European countries, USA, and European Commission delegated by their governments to prepare a report on whether supporting the construction to its completion would be reasonable. In the course of inspection the experts from USA and EU expressed doubts concerning two systems, namely, the containment and scram. These two points are discussed in the present paper. Three type of containments are proposed and an analysis of their efficiency is presented. The PIK reactor is controlled by eight rods in the heavy-water reflector -and an absorbing cylinder at the boundary between the core and the central light-water neutron trap. The rods are used for emergency protection and reactor start-up. The central control cylinder called here the shutter serves several functions, namely, as scram, automatic control, and burnup compensation. The delay time before the onset of negative reactivity is 1.05 sec for rods and 0.25 sec for the shutter

The association between oral contraceptive (OC) pills and vascular diseases is well-known, although, the present generation of pills is considered to be relatively safer in this regard. Hormonal treatment for severe abnormal uterine bleeding is usually considered after ruling out malignancy, when such bleeding is resistant to all other forms of treatment. We report a case of severe peripheral arterial disease in a female, who had been on high-dose OC pills for an extended period of time for severe uterine bleeding.

Are we overestimating the stroke risk related to contraceptive pills?

Science.gov (United States)

Gompel, Anne; Plu-Bureau, Genevieve

2014-02-01

Hormonal contraceptives are used by million of women worldwide. Ischemic stroke is one of the major harmful effects of hormonal contraceptives, but remains a very uncommon disease before menopause. The increased risk of stroke under third and fourth-generation contraceptive pills and nonoral contraceptives has been recently highlighted. Given the benefits associated with combined hormonal contraceptives (COCs), it is important to properly evaluate their risks in order to provide a better benefit/risk balance to young women. Scarce studies addressing the rates of stroke in young women suggest that the fraction attributable to the contraceptive pill remains low. In contrast, there is abundant literature on the relative risks of stroke under COCs. The risk of arterial disease seems to be similar among users of second and third-generation pills, drospirenone-containing pills and nonoral hormonal contraceptives. Progestin-only contraceptives do not appear to be associated with an increased risk of stroke. New formulations of hormonal contraceptives are not safer than second-generation COCs. Even if the absolute numbers of strokes attributable to hormonal contraceptives is very low, stringent selection of patients should help to reduce the events still more, and progestin-only contraceptives/nonhormonal methods should be preferred in cases of associated risk factors.

The Optimizing Strategies for Prescription of Sleeping Pills for Insomnia Patients

Directory of Open Access Journals (Sweden)

Full Text Available Many patients claim that they cannot sleep well despite ingestion of sleeping pills. In such cases, the physician should explore the reason why sleep disturbance persisted in patients despite administration of sleeping pills. We should consider patients’ age, gender, medical or psychiatric diseases, workplace, or sleep environment that may influence patients’ sleep and satisfaction with their hypnotics. However, prior to prescribing a hypnotic agent for patients with sleep disturbance, good sleep hygiene education should be provided first. Cognitive-behavioral therapy for insomnia is an important and effective treatment modality to improve patients’ sleep quality and reduce dosage of sleeping pills, but it is not easy for most general practitioners to learn and practice this modality. Therefore, we need to consider how to optimize the prescription of hypnotics for treating insomnia in order to prescribe hypnotics safely and appropriately at the lowest dosage. Physician should consider the mechanism of action of each hypnotic agent and prescribe proper hypnotics according to patients’ comorbid illness, insomnia types, or other underlying sleep disorders. Also, we should instruct the patients about when they should take their sleeping pills and we should monitor whether they have followed the instructions or not. Hospitalized patients are in a different sleep environment compared to outpatients, and therefore, we should also prepare modified management strategies for inpatients. In this review, strategies for optimizing the prescription of sleeping pills for insomnia patients will be discussed.

Urticarial Vasculitis (UV) is in most of the cases idiopathic; however it has been associated with several conditions and drugs. Over the counter (OTC) diet pills are widely available, even on-line, but they are rarely regulated by pharmaceutical control. We present the case of a 35-year-old female patient suffering of pruriginous and painful wheals more than 1 cm in diameter, with a burning sensation. The eruption lasted more than 24 hours and was accompanied by angioedema, headache and myalgia. No remarkable medical history was found, except for previous intake of OTC diet pills. UV diagnosis was confirmed by the skin biopsy of a lesion. OTC diet pills are widely available worldwide, and due to its widespread use, allergologists and dermatologist should be able to recognize symptoms and lesions of cutaneous vasculitis, which may be under reported.

To quantify the physical characteristics of sticks of traditional Chinese medicine (TCM) honeyed pills prepared by the plastic molded method and the correlation of adhesiveness and plasticity-related parameters of sticks and quality of pills, in order to find major parameters and the appropriate range impacting pill quality. Sticks were detected by texture analyzer for their physical characteristic parameters such as hardness and compression action, and pills were observed by visual evaluation for their quality. The correlation of both data was determined by the stepwise discriminant analysis. Stick physical characteristic parameter l(CD) can exactly depict the adhesiveness, with the discriminant equation of Y0 - Y1 = 6.415 - 41.594l(CD). When Y0 Y1, pills were adhesive with each other. Pills' physical characteristic parameters l(CD) and l(AC), Ar, Tr can exactly depict smoothness of pills, with the discriminant equation of Z0 - Z1 = -195.318 + 78.79l(AC) - 3 258. 982Ar + 3437.935Tr. When Z0 Z1, pills were rough on surface. The stepwise discriminant analysis is made to show the obvious correlation between key physical characteristic parameters l(CD) and l(AC), Ar, Tr of sticks and appearance quality of pills, defining the molding process for preparing pills by the plastic molded and qualifying ranges of key physical characteristic parameters characterizing intermediate sticks, in order to provide theoretical basis for prescription screening and technical parameter adjustment for pills.

Data from France's National Institute of Demographic Studies indicate that in 1986, 778,859 infants were born in France, including 80,874 to foreign mothers. France's total fertility rate was 1.83, higher than the 1.40 of the Federal Republic of Germany or the 1.35 of Italy but not high enough to ensure replacement. A 1988 survey by the National Institute of Demographic Studies indicated that almost 2/3 of fertile-aged French women used pills or IUDs. 7% had undergone sterilization, 4% were infertile, 13% had no partners, and 10% were pregnant or desired to become pregnant. All the developed countries, regardless of their form of government, have low fertility rates. The complete explanations of the trend to low fertility are not known. Economic and sociological explanations probably carry less weight than psychological factors. The desire for material goods, greater freedom of women, changing roles of men in the family and society, and fragility of marriages probably all play a part. The pill and to a lesser extent abortion have been blamed for the declining fertility, but do not furnish the complete explanation. Greater availability of RU 486 may cause further decline, but nobody can predict with assurance. Falling nuptiality, increased nonmarital cohabitation with its low fertility rates, the low rate of remarriage after divorce, and the greater life expectancy of women all affect France's population structure and prospects. By 2010, some 20% of the European population will be aged 65 and over. By 2035 almost 10 million persons will be over 70 years old in France, and nearly 2/3 of them will be female. This large cohort of elderly will require expensive care that the smaller young cohorts will be expected to finance. Intergenerational solidarity, however, already shows signs of strain. Serious conflicts will inevitably arise over the care and maintenance of this large elderly population group and will be exacerbated by the uneven population structure resulting

Industrialization and environmental pollution are bringing more problems to human reproduction and increasing the prevalence of male infertility. Western medicine has shown its limitations in the management of male infertility, especially that of oligoasthenospermia. Traditional Chinese medicine (TCM), however, has long and rich experiences in the treatment of oligoasthenospermia, with a large variety of medicinal prescriptions based on the TCM theories, among which Qilin Pills shows a particularly significant therapeutic effect on oligoasthenospermia, especially when combined with Western medicine. At present, published studies on Qilin Pills are mainly in the stage of clinical observation, while basic researches and studies on its relevant mechanisms are rarely seen.

Shunaoxin pills, a traditional Chinese medicine (TCM) product, have been used to treat cerebrovascular diseases in China since 2005. The main active components of Shunaoxin pills are ferulic acid and ligustilide from Chuanxiong (Ligusticum chuanxiong Hort, Umbelliferae) and Danggui (Angelica sinensis radix, Umbelliferae). As Shunaoxin shows excellent activity in the central nervous system (CNS), the extent to which the major constituents of Shunaoxin reach the CNS should be investigated. Moreover, the in vivo-in vitro correlations (IVIVC) of the formulation should be studied to elucidate the mechanisms of action of TCM in the CNS. However, these data have not previously been available. Thus we intended to investigate what the extent when these constituents of Shunaoxin pills reach the CNS, and evaluate the IVIVC of release and pharmacokinetics. In this study, we evaluated the release of ferulic acid and ligustilide from Shunaoxin pills, and their transport across an in vitro model of the BBB. We also evaluated their pharmacokinetics and brain distribution in vivo. High-performance liquid chromatography (HPLC) was used to quantify both compounds simultaneously. Based on the release in vitro and absorption of ferulic acid and ligustilide in vivo, IVIVC permitted prediction of the pharmacokinetics of these compounds. The release of ferulic acid and ligustilide reached a platform phase within 1h. Ferulic acid and ligustilide rapidly crossed the BBB in different patterns; the transport ratio increased over time. After intragastric (i.g.) administration of Shunaoxin pills, ferulic acid and ligustilide were rapidly absorbed and distributed into brain, which may result in a rapid onset of action. Ferulic acid and ligustilide were transported across a model BBB. After i.g. administration of Shunaoxin pills, ferulic acid and ligustilide were rapidly absorbed and distributed in brain; this may lead to rapid pharmacological onset. The IVIVC can be used to predict in vivo

2017-01-01

From November 2014 to November 2015, an experiment in French community pharmacies replaced traditional pre-packed boxes by per-unit dispensing of pills in the exact numbers prescribed, for 14 antibiotics. A cluster randomised control trial was carried out in 100 pharmacies. 75 pharmacies counted out the medication by units (experimental group), the other 25 providing the treatment in the existing pharmaceutical company boxes (control group). Data on patients under the two arms were compared to assess the environmental, economic and health effects of this change in drug dispensing. In particular, adherence was measured indirectly by comparing the number of pills left at the end of the prescribed treatment. Out of the 1185 patients included during 3 sessions of 4 consecutive weeks each, 907 patients experimented the personalized delivery and 278 were assigned to the control group, consistent with a 1/3 randomization-rate at the pharmacy level. 80% of eligible patients approved of the per-unit dispensing of their treatment. The initial packaging of the drugs did not match with the prescription in 60% of cases and per-unit dispensing reduced by 10% the number of pills supplied. 13.1% of patients declared that they threw away pills residuals instead of recycling-no differences between groups. Finally, per-unit dispensing appeared to improve adherence to antibiotic treatment (marginal effect 0.21, IC 95, 0.14-0.28). Supplying antibiotics per unit is not only beneficial in terms of a reduced number of pills to reimburse or for the environment (less pills wasted and non-recycled), but also has a positive and unexpected impact on adherence to treatment, and thus on both individual and public health.

Nonadherence to prescribed regimens for opioid analgesic agents contributes to increasing opioid abuse and overdose death. Opioids are frequently prescribed on an as-needed basis, placing the responsibility to determine opioid dose and frequency with the patient. There is wide variability in physician prescribing patterns because of the lack of data describing how patients actually use as-needed opioid analgesics. Digital pill systems have a radiofrequency emitter that directly measures medication ingestion events, and they provide an opportunity to discover the dose, timing, and duration of opioid therapy. The purpose of this study was to determine the feasibility of a novel digital pill system to measure as-needed opioid ingestion patterns in patients discharged from the emergency department (ED) after an acute bony fracture. We used a digital pill with individuals who presented to a teaching hospital ED with an acute extremity fracture. The digital pill consisted of a digital radiofrequency emitter within a standard gelatin capsule that encapsulated an oxycodone tablet. When ingested, the gastric chloride ion gradient activated the digital pill, transmitting a radiofrequency signal that was received by a hip-worn receiver, which then transmitted the ingestion data to a cloud-based server. After a brief, hands-on training session in the ED, study participants were discharged home and used the digital pill system to ingest oxycodone prescribed as needed for pain for one week. We conducted pill counts to verify digital pill data and open-ended interviews with participants at their follow-up appointment with orthopedics or at one week after enrollment in the study to determine the knowledge, attitudes, beliefs, and practices regarding digital pills. We analyzed open-ended interviews using applied thematic analysis. We recruited 10 study participants and recorded 96 ingestion events (87.3%, 96/110 accuracy). Study participants reported being able to operate all

Modal analysis of wake fields and its application to elliptical pill-box cavity with finite aperture

The potential of the wake-field produced by a bunch of relativistic charged particles passing through a pill-box cavity is expressed by using Floquet's theorem, and an obvious requirement that the energy gain over all acceleration cavity of many pill boxes must be proportional to the number of pill boxes, based on the previous modal approach (BWW theory). It is found that the wake-field is consisted of two classes of modes: the longitudinal modes which are independent of the aperture and the pill-box gap, the hybrid (pill-box) modes which are dependent of the pill-box gap. The wake field is predominated by the fundamental longitudinal mode whose wavelength is on the order of the effective diameter of the cavity, and its magnitude is inversely proportional to the cross sectional area of the cavity for practical cavities with small apertures. Both longitudinal and transverse wake fields due to the longitudinal modes in an elliptical pill box cavity are expressed analytically in a closed series form by solving exactly the longitudinal eigenmode equation in the elliptical cylindrical coordinates in terms of Mathieu functions. It is found that both longitudinal and transverse wake fields whose amplitudes per driving charge are greater than 100 MV/m/μC can be generated in an elliptical cavity

To determine the content and release kinetics of 1-benzylpiperazine (BZP) and 1-(3-trifluoromethyl-phenyl)piperazine (TFMPP) from "party pill" formulations. From these data, the possible impact of pharmaceutical quality upon the safety of such illicit formulations may be inferred. The amount of BZP and TFMPP in party pill formulations was determined using a validated HPLC method. The in-vitro release kinetics of selected party pill brands were determined using a USP dissolution apparatus (75 rpm, 37.5 degrees Celsius). The release data were then fitted to a first order release model using PLOT software and the time taken to achieve 90% release reported. Many of the tested party pill brands contained amounts of BZP and TFMPP that varied considerably from that stated on the packaging; including considerable TFMPP content in some brands not labelled to contain this drug. Dissolution studies revealed that there was considerable variability in the release kinetics between brands; in one case 90% release required >30 minutes. Lack of quality control in party pill manufacture may have led to the toxic effects reported by users unaware of the true content and release of drug from pills. More stringent regulation in the manufacture and quality control of "new generation party pills" is essential to the harm reduction campaign.

Risky sexual activity among adolescents is on the increase and contraceptive prevalence rate is low which is evidenced by high rate of teenage pregnancy in Bayelsa state, Nigeria. This study assesses the adolescents' knowledge, attitude and utilization of emergency contraceptive pills (ECP) in Amassoma Community, Bayelsa State, in the Niger Delta region of Nigeria. The study was a descriptive cross-sectional research design. A purposive sampling technique was used to select a sample of 220 respondents from the target population. Data were collected using a self-structured questionnaire. Descriptive and inferential statistics were used to analyze the data generated. Majority of the respondents had high level of knowledge and positive attitude towards emergency contraceptive pills but had low level of utilization. Concerns about what others may say, parental attitude, contraceptive availability, contraceptive accessibility, and peer influences were the major factors that influenced the utilization of contraceptive pills. There was no significant relationship between knowledge and utilization of emergency contraceptive pills, as well as level of knowledge and their utilization of emergency contraceptive pills. Adolescents in the study were more likely to use emergency contraceptive pills, if parents and others reaction to adolescents' contraceptive use were positive about those. Health care professionals, especially nurses, should organize enlightenment programs to educate adolescents, parents and the public on the benefits of adolescents' contraceptives use, especially ECP.

The Administration of Tibetan Precious Pills: Efficacy in Historical and Ritual Contexts.

Science.gov (United States)

Czaja, Olaf

2015-01-01

Precious pills represent a special kind of Tibetan drug that once was, and still is, highly sought after by Tibetan, Chinese, and Mongolian patients. Such pills are generally taken as a potent prophylactic remedy, and can be used to cure various diseases. The present study seeks to discuss the dispensation and efficacy of precious pills according to the presentations of historical Tibetan medical scholars. Several treatises dealing with these instructions will be analysed, thereby revealing their underlying concepts, and highlighting their points of both general consensus and disagreement. The analysis of these detailed instructions will reveal the fact that these precious pills were not merely given to a patient but, in order to ensure their full efficacy, involved an elaborate regimen concerning three chronological periods: (1) the time of preparation, (2) the time of dispensation, and (3) the time after dispensation. Thus the present study surveys not only the ritual empowerment of drugs in Tibetan medicine, but also the importance of social relationships between doctors and patients in Tibetan medical history.

The utility value attributed to taking pills for prevention can have a major effect on the cost-effectiveness of interventions, but few published studies have systematically quantified this value. We sought to quantify the utility value of taking pills used for prevention of cardiovascular disease (CVD). Cross-sectional survey. Central North Carolina. 708 healthcare employees aged 18 years and older. Utility values for taking 1 pill/day, assessed using time trade-off, modified standard gamble and willingness-to-pay methods. Mean age of respondents was 43 years (19-74). The majority of the respondents were female (83%) and Caucasian (80%). Most (80%) took at least 2 pills/day. Mean utility values for taking 1 pill/day using the time trade-off method were: 0.9972 (95% CI 0.9962 to 0.9980). Values derived from the standard gamble and willingness-to-pay methods were 0.9967 (0.9954 to 0.9979) and 0.9989 (95% CI 0.9986 to 0.9991), respectively. Utility values varied little across characteristics such as age, sex, race, education level or number of pills taken per day. The utility value of taking pills daily in order to prevent an adverse CVD health outcome is approximately 0.997. Published by the BMJ Publishing Group Limited.

BACKGROUND: Combined oral contraceptive pills were the first contraceptive method to provide sexual freedom of choice for women through reliable, personal and private control of fertility. They are the most widely used hormonal contraceptives and also the most popular non-surgical method of contraception. OBJECTIVE: To review the profile of acceptors of combined oral contraceptive pills at the University of Uyo Teaching Hospital, Uyo. METHODOLOGY: An 8 year review of all clients that accepted combined oral contraceptive pills in the family planning clinic. RESULTS: There were 1,146 new contraceptive acceptors during the period of study out of which 309 (27.9%) accepted the pills. Majority of the clients were between 20 and 29 years of age (54.0%), were multiparous (72.8%), Christians (99.7%) and 61.2% had tertiary level education. Two hundred and fifty-five women (82.5%) desired to use combined oral contraceptive pills to space births while 7.8% wanted to limit child bearing. There was a high discontinuation rate among the women (45.0%) and out of these 87.9% of the clients changed to other contraceptive methods. All the clients commenced their pills within seven days of menstruation and only the low dose monophasic preparations were available in the family planning unit and thus were given to the clients. CONCLUSION: Women who accept to initiate combined oral contraceptive pills in our center are young, well educated, multiparous women who want to space their pregnancies. However, due to the high discontinuation rate among the clients, there is need for further studies evaluating reasons for the high discontinuation rate, exploring interactions between clients and providers' and also providers' attitude towards combined pills in our environment.

Endothelial progenitor cells (EPCs) are capable of proliferating and differentiating into mature endothelial cells, and they have been considered as potential candidates for coronary heart disease therapy. However, the transition of EPCs to mesenchymal cells is not fully understood. This study aimed to explore the role of microRNA 126 (miR-126) in the endothelial-to-mesenchymal transition (EndMT) induced by transforming growth factor beta 1 (TGFβ1). EndMT of rat bone marrow-derived EPCs was induced by TGFβ1 (5 ng/mL) for 7 days. miR-126 expression was depressed in the process of EPC EndMT. The luciferase reporter assay showed that the PI3K regulatory subunit p85 beta (PIK3R2) was a direct target of miR-126 in EPCs. Overexpression of miR-126 by a lentiviral vector (lenti-miR-126) was found to downregulate the mRNA expression of mesenchymal cell markers (α-SMA, sm22-a, and myocardin) and to maintain the mRNA expression of progenitor cell markers (CD34, CD133). In the cellular process of EndMT, there was an increase in the protein expression of PIK3R2 and the nuclear transcription factors FoxO3 and Smad4; PI3K and phosphor-Akt expression decreased, a change that was reversed markedly by overexpression of miR-126. Furthermore, knockdown of PIK3R2 gene expression level showed reversed morphological changes of the EPCs treated with TGFβ1, thereby giving the evidence that PIK3R2 is the target gene of miR-126 during EndMT process. These results show that miR-126 targets PIK3R2 to inhibit EPC EndMT and that this process involves regulation of the PI3K/Akt signalling pathway. miR-126 has the potential to be used as a biomarker for the early diagnosis of intimal hyperplasia in cardiovascular disease and can even be a therapeutic tool for treating cardiovascular diseases mediated by the EndMT process.

Phosphate binders (PBs) account for about one half of the daily pill burden for US hemodialysis (HD) patients, which may reduce adherence. Adherence can be estimated by the medication possession ratio (MPR), which is defined as the proportion of time a patient had sufficient medication to have taken it as prescribed. Gaps of time between prescription fills lower the patient's MPR. We assessed the association of PB pill burden and adherence (MPR) with phosphorus goal attainment. Using pharmacy management program data, HD patients on PB monotherapy were tracked from first PB fill during 1 January 2007-30 June 2011 for 1 year, or until PB change or censoring. Data were assessed with generalized linear models. We analyzed 8616 patients. Higher pill burden was associated with lower adherence. Lower adherence tended to be associated with higher mean phosphorus levels and lower percentage of patients with serum phosphorus ≤5.5 mg/dL (P adherence and these clinical outcomes was most pronounced in the lowest and highest pill burden strata (3-6, >12-15, >15). Adherence, as measured by the MPR, was negatively related to higher pill burden and phosphorus levels and positively related to patients in the phosphorus target range. Within pill burden strata, phosphorus increased and patients in the target range generally decreased with decreasing adherence, suggesting that patients prescribed fewer PB pills are less likely to have treatment gaps, and may be more likely to achieve phosphorus targets. © The Author 2013.

Salt pill design and fabrication for adiabatic demagnetization refrigerators

Science.gov (United States)

Shirron, Peter J.; McCammon, Dan

2014-07-01

The performance of an adiabatic demagnetization refrigerator (ADR) is critically dependent on the design and construction of the salt pills that produce cooling. In most cases, the primary goal is to obtain the largest cooling capacity at the low temperature end of the operating range. The realizable cooling capacity depends on a number of factors, including refrigerant mass, and how efficiently it absorbs heat from the various instrument loads. The design and optimization of “salt pills” for ADR systems depend not only on the mechanical, chemical and thermal properties of the refrigerant, but also on the range of heat fluxes that the salt pill must accommodate. Despite the fairly wide variety of refrigerants available, those used at very low temperature tend to be hydrated salts that require a dedicated thermal bus and must be hermetically sealed, while those used at higher temperature - greater than about 0.5 K - tend to be single- or poly-crystals that have much simpler requirements for thermal and mechanical packaging. This paper presents a summary of strategies and techniques for designing, optimizing and fabricating salt pills for both low- and mid-temperature applications.

Cohen, Bruce M Z; Butler, Rachael

2011-03-01

BZP-party pills are yet another 'designer drug' which mimics the stimulant qualities of amphetamines and MDMA/Ecstasy. As legal markets for the substance have developed in the last decade (especially amongst young people) so has public and governmental concern. This article provides a summary of the available international research on benzylpiperazine (BZP) and its popular use in the compound form known as 'party pills'. Through performing an analysis of the available medical and social scientific literature, the review outlines current knowledge on the compound, the prevalence of usage of BZP-party pills, as well as the associated harms, risks and rationales for use of the drug. Despite moves towards legislative control of BZP-party pills, the evidence presented suggests limited social and health harms associated with the drug, although research on long term effects is a significant gap in the literature. It also remains inconclusive as to whether BZP-party pills act as a 'gateway' to illegal drugs or, conversely, play a role in harm reduction with illegal drug users turning to legal alternatives; there is some evidence for both positions. With increasing controls of BZP-party pills, and with the increasing numbers of 'legal highs' and new designer drugs on the market, we conclude that new legal alternatives will continue to surface to replace the drug in the future. Considering a harm reduction approach to drug taking, it is suggested that policy makers consider the creation of a legal holding category which restricts and regulates the market in legal highs whilst the social and health harms associated with each drug can be thoroughly investigated.

The Potsdam Parallel Ice Sheet Model (PISM-PIK – Part 1: Model description

Directory of Open Access Journals (Sweden)

R. Winkelmann

2011-09-01

Full Text Available We present the Potsdam Parallel Ice Sheet Model (PISM-PIK, developed at the Potsdam Institute for Climate Impact Research to be used for simulations of large-scale ice sheet-shelf systems. It is derived from the Parallel Ice Sheet Model (Bueler and Brown, 2009. Velocities are calculated by superposition of two shallow stress balance approximations within the entire ice covered region: the shallow ice approximation (SIA is dominant in grounded regions and accounts for shear deformation parallel to the geoid. The plug-flow type shallow shelf approximation (SSA dominates the velocity field in ice shelf regions and serves as a basal sliding velocity in grounded regions. Ice streams can be identified diagnostically as regions with a significant contribution of membrane stresses to the local momentum balance. All lateral boundaries in PISM-PIK are free to evolve, including the grounding line and ice fronts. Ice shelf margins in particular are modeled using Neumann boundary conditions for the SSA equations, reflecting a hydrostatic stress imbalance along the vertical calving face. The ice front position is modeled using a subgrid-scale representation of calving front motion (Albrecht et al., 2011 and a physically-motivated calving law based on horizontal spreading rates. The model is tested in experiments from the Marine Ice Sheet Model Intercomparison Project (MISMIP. A dynamic equilibrium simulation of Antarctica under present-day conditions is presented in Martin et al. (2011.

Emergency contraceptive pills: Exploring the knowledge and attitudes of community health workers in a developing Muslim country.

Unsafe abortion is a major Public health problem in developing countries, where women make several unsafe attempts at termination of the unintended pregnancy before turning to health services. Community health workers can act as a bridge between the community and their health facilities and can use Emergency Contraceptive Pills to significantly reduce the mortality and morbidity related to unsafe abortions. This study explores the knowledge, attitudes and practices of the Lady Health Supervisor of the National Program for Family Planning, district Rawalpindi, regarding emergency contraception pills. The cross sectional survey was conducted during the monthly meeting of Lady Health Supervisors. Self administered, anonymous and voluntary questionnaire consisting of 17 items, regarding demographic profile, awareness, knowledge, attitudes and practices, was used. Insufficient knowledge, high misinformation and strongly negative attitudes were revealed. More than half did not know that emergency contraceptive pills do not cause abortion. About four fifths believed that emergency contraceptive pills will lead to 'evil' practices in society. More than four fifths recognized that the clients of National Program for Family Planning need emergency contraceptive pills. The attitudes were significantly associated with knowledge (P=0.034, Fisher's Exact Test). The awareness of emergency contraceptive pills is high. Serious gaps in knowledge have been identified. There is a clear recognition of the need of emergency contraceptive pills for the clients of National Program for Family Planning. However, any strategy to introduce emergency contraceptive pills must cater for the misplaced beliefs of the work force.

New low-dose, extended-cycle pills with levonorgestrel and ethinyl estradiol: an evolutionary step in birth control.

Science.gov (United States)

Nelson, Anita

2010-08-09

To review milestones in development of oral contraceptive pills since their introduction in the US 50 years ago in order to better understand how a new formulation with low-dose estrogen in an extended-cycle pattern fits into the evolution of birth control pills. This is a review of trends in the development of various birth controls pills and includes data from phase III clinical trials for this new formulation. The first birth control pill was a very high-dose monophasic formulation with the prodrug estrogen mestranol and a first-generation progestin. Over the decades, the doses of hormones have been markedly reduced, and a new estrogen and several different progestins were developed and used in different dosing patterns. The final element to undergo change was the 7-day pill-free interval. Many of these same changes have been made in the development of extended-cycle pill formulation. The newest extended-cycle oral contraceptive formulation with 84 active pills, each containing 20 μg ethinyl estradiol and 100 μg levonorgestrel, represents an important evolution in birth control that incorporates lower doses of estrogen (to reduce side effects and possibly reduce risk of thrombosis), fewer scheduled bleeding episodes (to meet women's desires for fewer and shorter menses) and the use of low-dose estrogen in place of placebo pills (to reduce the number of days of unscheduled spotting and bleeding). Hopefully, this unique formation will motivate women to be more successful contraceptors.

Full Text Available To examine the in vitro and in vivo efficacy of the dual PI3K/mTOR inhibitor NVP-BEZ235 in treatment of PIK3CA wild-type colorectal cancer (CRC.PIK3CA mutant and wild-type human CRC cell lines were treated in vitro with NVP-BEZ235, and the resulting effects on proliferation, apoptosis, and signaling were assessed. Colonic tumors from a genetically engineered mouse (GEM model for sporadic wild-type PIK3CA CRC were treated in vivo with NVP-BEZ235. The resulting effects on macroscopic tumor growth/regression, proliferation, apoptosis, angiogenesis, and signaling were examined.In vitro treatment of CRC cell lines with NVP-BEZ235 resulted in transient PI3K blockade, sustained decreases in mTORC1/mTORC2 signaling, and a corresponding decrease in cell viability (median IC(50 = 9.0-14.3 nM. Similar effects were seen in paired isogenic CRC cell lines that differed only in the presence or absence of an activating PIK3CA mutant allele. In vivo treatment of colonic tumor-bearing mice with NVP-BEZ235 resulted in transient PI3K inhibition and sustained blockade of mTORC1/mTORC2 signaling. Longitudinal tumor surveillance by optical colonoscopy demonstrated a 97% increase in tumor size in control mice (p = 0.01 vs. a 43% decrease (p = 0.008 in treated mice. Ex vivo analysis of the NVP-BEZ235-treated tumors demonstrated a 56% decrease in proliferation (p = 0.003, no effects on apoptosis, and a 75% reduction in angiogenesis (p = 0.013.These studies provide the preclinical rationale for studies examining the efficacy of the dual PI3K/mTOR inhibitor NVP-BEZ235 in treatment of PIK3CA wild-type CRC.

In this paper, a design space approach was applied to optimize the dropping process of Ginkgo biloba dropping pills. Firstly, potential critical process parameters and potential process critical quality attributes were determined through literature research and pre-experiments. Secondly, experiments were carried out according to Box-Behnken design. Then the critical process parameters and critical quality attributes were determined based on the experimental results. Thirdly, second-order polynomial models were used to describe the quantitative relationships between critical process parameters and critical quality attributes. Finally, a probability-based design space was calculated and verified. The verification results showed that efficient production of Ginkgo biloba dropping pills can be guaranteed by operating within the design space parameters. The recommended operation ranges for the critical dropping process parameters of Ginkgo biloba dropping pills were as follows: dropping distance of 5.5-6.7 cm, and dropping speed of 59-60 drops per minute, providing a reference for industrial production of Ginkgo biloba dropping pills.

Most women taking combined oral contraceptives (COCs) are satisfied with their contraceptive method. However, one of the most common reasons reported for discontinuation of combined oral contraceptives (COCs) is mood deterioration. This study aimed to compare effects of the second and third generation oral contraceptive pills on the mood of reproductive women. This randomized, double-blind, controlled clinical trial was conducted in reproductive women at health centers in Tehran, Iran. Participants were randomized into the second and third generation oral contraceptive groups. Positive and negative moods were recorded using positive affect, negative affect scale (PANAS) tools at the end the second and fourth months of the study. Data analysis was carried out using ANOVA and P Values pills. The second generation oral contraceptive pills resulted in a decrease in positive mood (95% CI: 43.39 to 38.32 in second month and 43.39 to 26.05 in four month) and increase in negative mood (95% CI: 14.23 to 22.04 in second month and 14.23 to 32.26 in four month - P pills have a better effect on mood in women in reproductive ages than the second generation pills. It can be recommended as a proper combined oral contraceptive in Iran.

South Delhi is one of the well developed districts in the capital with best public health care facilities. Knowledge, attitude and dispensing practices of emergency contraceptive pills (E-pills) were assessed among health care providers of government dispensaries in South Delhi. A descriptive epidemiological study. Both medical and paramedical (n = 428) providers in 63 government health care facilities were interviewed between August to December 2007 using a semi-structured interview schedule. Among the different categories of the providers, medical officers were observed to be most knowledgeable about E-pills and the pharmacists were the least. The correct prescribed dose of E-pill was known only to 32% of the providers while 49% knew about its right time of intake. Misconceptions and apprehensions for promoting its use were very much prevalent even among medical officers as majority felt that open access to E-pills would increase promiscuity. The dispensing practice of providers was found positively (P pills.

Does the contraceptive pill alter mate choice in humans?

Science.gov (United States)

Alvergne, Alexandra; Lummaa, Virpi

2010-03-01

Female and male mate choice preferences in humans both vary according to the menstrual cycle. Women prefer more masculine, symmetrical and genetically unrelated men during ovulation compared with other phases of their cycle, and recent evidence suggests that men prefer ovulating women to others. Such monthly shifts in mate preference have been suggested to bring evolutionary benefits in terms of reproductive success. New evidence is now emerging that taking the oral contraceptive pill might significantly alter both female and male mate choice by removing the mid-cycle change in preferences. Here, we review support for such conclusions and speculate on the consequences of pill-induced choice of otherwise less-preferred partners for relationship satisfaction, durability and, ultimately, reproductive outcomes.

To evaluate its mechanism of inducing the maternal-fetal immune tolerance by studying the effects of Shoutai pills on the expression of Th1/Th2 cytokine and pregnancy in maternal-fetal interface of mice with recurrent spontaneous abortion (RSA). The normal pregnancy and RSA model were respectively induced with CBA/J x BALB/c and CBA/J x DBA/2. The mice with RSA were randomly divided into model group and low, middle and high dose groups of Shoutai pills. The mice were killed in 14 days after administration and embryo resorption rate was counted and their decidual and placental tissues were co-cultured to detect the expressions of IL-4, IL-10, IFN-gamma and TNF-alpha with ELISA. The embryo resorption rate of the model group was significantly higher than the normal pregnancy, middle and high dose groups of Shoutai pills could decreased the embryo resorption rate of the mice with RSA (P pills could decreased the expression of IFN-gamma and TNF-alpha (P pills. Middle and high doses of Shoutai pills could increased the expression of IL-4 and IL-10 (P pills. The mechanism about Shoutai pills can change Th1 /Th2 cytokine towards Th2 bias, which induced the maternal-fetal immune tolerance.

3,4-Methylenedioxymethamphetamine (MDMA) is the major ingredient of ecstasy illicit pills. It is a hallucinogen, central nervous system stimulant, and serotonergic neurotoxin that strongly releases serotonin from serotonergic nerves terminals. Moreover, it releases norepinephrine and dopamine from nerves terminal, but to a lesser extent than serotonin. Poisoning and even death from abusing MDMA-containing ecstasy illicit pills among abusers is usual. Thus, quantitative determination of MDMA content of ecstasy illicit pills in illicit drug bazaar must be done regularly to find the most high dose ecstasy illicit pills and removing them from illicit drug bazaar. In the present study, MDMA contents of 13 most abundant ecstasy illicit pills were determined by quantitative thin-layer chromatography (TLC). Two procedures for quantitative determination of MDMA contents of ecstasy illicit pills by TLC were used: densitometric and so-called 'scraping off' methods. The former was done in a reflection mode at 285 nm and the latter was done by absorbance measurement of eluted scraped off spots. Limit of detection (LOD), considering signal-to-noise ratio (S/N) of 2, and limit of quantification (LOQ), regarding S/N of 10, of densitometric and scraping off methods were 0.40 microg, 1.20 microg, and 6.87 mug, 20.63 microg, respectively. Repeatabilities (within-laboratory error) of densitometric and scraping off methods were 0.5% and 3.6%, respectively. The results showed that the ecstasy illicit pills contained 24-124.5 mg and 23.9-122.2 mg MDMA by densitometric and scraping off methods, respectively.

Background and Objective: Risky sexual activity among adolescents is on the increase and contraceptive prevalence rate is low which is evidenced by high rate of teenage pregnancy in Bayelsa state, Nigeria. This study assesses the adolescents’ knowledge, attitude and utilization of emergency contraceptive pills (ECP) in Amassoma Community, Bayelsa State, in the Niger Delta region of Nigeria. Methods: The study was a descriptive cross-sectional research design. A purposive sampling technique was used to select a sample of 220 respondents from the target population. Data were collected using a self-structured questionnaire. Descriptive and inferential statistics were used to analyze the data generated. Results: Majority of the respondents had high level of knowledge and positive attitude towards emergency contraceptive pills but had low level of utilization. Concerns about what others may say, parental attitude, contraceptive availability, contraceptive accessibility, and peer influences were the major factors that influenced the utilization of contraceptive pills. There was no significant relationship between knowledge and utilization of emergency contraceptive pills, as well as level of knowledge and their utilization of emergency contraceptive pills. Conclusions and Global Health Implications: Adolescents in the study were more likely to use emergency contraceptive pills, if parents and others reaction to adolescents’ contraceptive use were positive about those. Health care professionals, especially nurses, should organize enlightenment programs to educate adolescents, parents and the public on the benefits of adolescents’ contraceptives use, especially ECP.

Full Text Available AIMS: Endothelial progenitor cells (EPCs are capable of proliferating and differentiating into mature endothelial cells, and they have been considered as potential candidates for coronary heart disease therapy. However, the transition of EPCs to mesenchymal cells is not fully understood. This study aimed to explore the role of microRNA 126 (miR-126 in the endothelial-to-mesenchymal transition (EndMT induced by transforming growth factor beta 1 (TGFβ1. METHODS AND RESULTS: EndMT of rat bone marrow-derived EPCs was induced by TGFβ1 (5 ng/mL for 7 days. miR-126 expression was depressed in the process of EPC EndMT. The luciferase reporter assay showed that the PI3K regulatory subunit p85 beta (PIK3R2 was a direct target of miR-126 in EPCs. Overexpression of miR-126 by a lentiviral vector (lenti-miR-126 was found to downregulate the mRNA expression of mesenchymal cell markers (α-SMA, sm22-a, and myocardin and to maintain the mRNA expression of progenitor cell markers (CD34, CD133. In the cellular process of EndMT, there was an increase in the protein expression of PIK3R2 and the nuclear transcription factors FoxO3 and Smad4; PI3K and phosphor-Akt expression decreased, a change that was reversed markedly by overexpression of miR-126. Furthermore, knockdown of PIK3R2 gene expression level showed reversed morphological changes of the EPCs treated with TGFβ1, thereby giving the evidence that PIK3R2 is the target gene of miR-126 during EndMT process. CONCLUSIONS: These results show that miR-126 targets PIK3R2 to inhibit EPC EndMT and that this process involves regulation of the PI3K/Akt signalling pathway. miR-126 has the potential to be used as a biomarker for the early diagnosis of intimal hyperplasia in cardiovascular disease and can even be a therapeutic tool for treating cardiovascular diseases mediated by the EndMT process.

2007-12-01

Full Text Available Abstract Background In a number of drug and psychotherapy comparative trials, psychotherapy-placebo combination has been assumed to represent psychotherapy. Whether psychotherapy plus pill placebo is the same as psychotherapy alone is an empirical question which however has to date never been examined systematically. Methods We conducted a systematic review and meta-analysis of randomised controlled trials (RCTs that directly compared cognitive-behavior therapy (CBT alone against CBT plus pill placebo in the treatment of panic disorder. Results Extensive literature search was able to identify three relevant RCTs. At the end of the acute phase treatment, patients who received CBT plus placebo had 26% (95%CI: 2 to 55% increased chances of responding than those who received CBT alone. At follow-up the difference was no longer statistically significant (22%, 95%CI: -10% to 64%. Conclusion The act of taking a pill placebo may enhance the placebo effect already contained in the effective psychotherapeutic intervention during the acute phase treatment. Theoretically this is an argument against the recently claimed null hypothesis of placebo effect in general and clinically it may point to some further room for enhancing the psychotherapeutic approach for panic disorder.

In Nigeria about 50% of oral contraceptive pill users obtain their products from proprietary patent medicine vendors (PPMVs). This group of service providers are poorly trained and have very limited knowledge about contraception. This paper investigated the nature of the advice offered to simulated current and potential users of oral contraceptive pills. The main objective was to assess the nature and quality of advice provided by PPMVs to pill users. This study is based on findings from a 'mystery client' approach in which three scenarios related to contraceptive pill use were simulated. Each of the 12 mystery clients simulated one of the following three scenarios: new pill users (new to family planning or switching from condom to pills); user seeking a resupply of pills; and dissatisfied pill users intending to discontinue use. Simple random sampling was used to select 410 PPMVs from a total of 1,826 in four states in Nigeria. Qualitative study using in-depth interviews was also conducted. A majority of the PPMVs had pills in stock on the day of the survey and resupplied pills to the clients. PPMVs also understood the reason and importance of referring clients who were new adopters of oral contraceptive methods to a health facility; 30% of the PPMVs referred new adopters to a health facility. However, demand from clients who do not want to go to health care facilities (for various reasons) necessitated the provision of oral contraceptive pills to 41% of the first time users. Some PPMVs prescribed treatment to mystery clients who presented with perceived complications arising from the use of pills, while 49% were referred to a health facility. The advice given by PPMVs often falls short of safety guidelines related to the use of oral contraceptive pills. There is a need to continuously update knowledge among the PPMVs to ensure that they provide quality oral contraceptive services as PPMVs bridge the gap between medical experts and users in rural communities.

To study the prescription and technique of sustained-release dropping pills of curcumin and inspect their release property in vitro. The orthogonal test was used to screen the prescription and technique which were definited with the colligation evaluation of release and formation of dropping pills. The optimization of prescription and technique were as follows: stearic acid 70 mg, glycery monostearate 25 mg, solutol 6 mg, viscosity of cooling liquid was 100 mm2/s; the temperature of material liquid was 80 degrees C; the cooling temperature was 30 - 0 degrees C; the dropping speed was (21 +/- 2) dripping/min. The release behavior of sustained-release dropping pills of curcumin coincidented with Higuchi equation well and the character of sustained-release was transparent. The sustained-release dropping pills of curcumin have good property of sustained-release in vitro and their release behavior in vivo need to be inspected.

Antiretroviral treatment (ART) is hampered by complicated regimens, high pill burden, drug-drug interactions, and frequent short- and long-term adverse effects, leading to decreased adherence. Over recent years, considerable effort has been directed at developing regimens that are less burdening. We undertook a 7-year retrospective study of the records of 264 HIV-infected subjects enrolled in a pharmaceutical care programme to document the progress made and to study the influence of the number of ART pills and doses on the level of treatment adherence. Antiretroviral dispensing records were analysed for the number of pills and doses administered and the ART adherence rate estimated. In 2005, the patients took a mean of 6·2 pills daily (CI 95%: 5·9-6·6), and 92·9% of them were on a twice-a-day (BID) dosage regimen. By 2012, the mean number of pills was reduced to 4·1 (CI 95%: 3·8-4·4), and only 50·9% were on a BID regimen. No statistically significant relation was observed between number of daily pills and doses and ART adherence reached by the patients in any of the analyses performed. There has been a continuous reduction in the number of pills and doses of antiretrovirals taken by individual patients over the last 7 years due largely to the introduction of improved treatments and regimens. More daily pills or doses was not associated with worse ART adherence in our pharmaceutical care programme. © 2015 John Wiley & Sons Ltd.

To evaluate the clinical efficacy and safety of Qilin Pills in the treatment of oligoasthenospermia in infertile men. This multi-centered randomized double-blind controlled clinical trial included 216 infertile males with oligoasthenospermia, 108 in the trial group and the other 108 in the control, the former treated with Qilin Pills at the dose of 6 g tid while the latter with Wuziyanzong Pills at 6 g bid, both for 12 weeks. We examined the total sperm count, sperm motility and the count of progressively motile sperm of the patients before and at 4, 8 and 12 weeks after medication and evaluated the safety of the drug based on the adverse events and the laboratory results of blood and urine routine examinations and liver and kidney function tests. Compared with the baseline, the patients in the trial group showed a significant time-dependent improvement after 4, 8 and 12 weeks of medication in sperm motility (21.75% vs 27.54%, 29.04% and 32.95%, P Pills can evidently improve the semen quality of oligoasthenospermia patients with no obvious adverse events.

Suicide attempts (SAs) in the paediatric age group represent an important cause of morbidity and mortality. Our aim was to examine the factors affecting the decision to hospitalize children with a diagnosis of non-fatal SA by pills. Children pills during 2014 were evaluated retrospectively. Patients were divided into two groups: Group-I comprised hospitalised patients and Group-II included those who were discharged from the PED. These two groups were compared in terms of clinical and demographic characteristics recorded upon PED admission. A total of 196 patients were included in the study. The number of pills taken for self-poisoning in Group-I (median: 20 pills) was higher than that in Group-II (median: 12 pills) (p pills included the amount of medication taken for the suicide attempt and the presence of psychiatric disorders, as determined by a paediatric psychiatrist during the acute phase.

Therapeutic angiogenesis is a pivotal strategy for ischemic heart disease. The aim of the present study was to determine the effect and molecular mechanism of Shexiang Baoxin pills, a widely-used traditional Chinese medicine for ischemic heart disease, on angiogenesis in a rat model of myocardial infarction (MI). We used the occlusion of left anterior descending coronary artery of Sprague-Dawley rats as a model of MI. The MI rats were treated with distilled water, Shexiang Baoxin pills, or Shexiang Baoxin pills + HET0016 (a selective blocker of the biosynthesis of 20-hydroxyeicosatetraenoic acid (20-HETE) at 10 mg/kg/day), respectively. Sham-operated rats were used as controls. Treatment with Shexiang Baoxin pills increases the level of serum 20-HETE in MI rats, which can be suppressed by HET0016 treatment. Shexiang Baoxin pills shows cardio-protective effects on MI rats, including improving cardiac function, decreasing infarction area, and promoting angiogenesis in peri-infarct area. The protective effects of Shexiang Baoxin pills are partly inhibited by HET0016. Furthermore, Shexiang Baoxin pills enhances the number of circulating endothelial progenitor cells (EPCs) and the expression of the vascular endothelial growth factor (VEGF), based on immunohistochemical analysis, in peri-infarct area of MI rats, which is partly suppressed by HET0016. Shexiang Baoxin pills may partially participate in angiogenesis in MI rats. The protective mechanism of Shexiang Baoxin pills may be mediated via up-regulation of 20-HETE, which promotes EPCs mobilization and VEGF expression. Copyright © 2017 Elsevier B.V.

1999-09-01

This article focuses on the accessibility of emergency contraceptive pills (ECPs). The ECPs are safe, simple, and effective contraceptive agent that can reduce a woman's chance of becoming pregnant by 75%. It works by preventing or delaying ovulation, interfering with fertilization, or blocking implantation of a fertilized egg, depending on when in the menstrual cycle the pills are taken. The Population Council takes a multifaceted approach to expanding access to and knowledge on emergency contraception. Studies on innovations in service delivery are being conducted. In Mexico, one-tenth of women aged 13-55 who reported being raped during the 9-month study were counseled about ECPs. Results showed that pregnancies from reported rapes declined from 9.8% to 7.4% during the study. In Ho Chi Minh City, Vietnam, practitioners approved of the use of emergency contraception and desired more accurate knowledge so that they could provide it effectively. Moreover, in Zambia, researchers found out that giving women packages of ECPs in advance greatly reduced the length of time between having unprotected intercourse and beginning ECP treatment. Council researchers have also addressed the safety of offering ECPs without prescription. They have collaborated with leaders in the health care industry to increase method availability.

To study the relationship between HPLC characteristic spectrum and pharmacodynamics on anti-myocardial ischemia of GualouXiebai dropping pills. HPLC characteristic spectrum of GualouXiebai dropping pills was established, dropping pills were divided into five dose groups (3.75, 11.25, 22.5, 33.75 and 45 g/kg, equivalent to the crude herb g/kg), the mice were orally administered dropping pills once daily for 7 d, 90 min after the mice were given by intraperitoneal injection of isoprenaline to establish myocardial ischemia models, the level of CK in blood plasma were detected; Then, the correlation between characteristic spectrum and biochemical index CK was studied by grey relational analysis method. The correlation between each common peak and CK had gradually increased with the dose increased from 3.73 g/kg to 33.75 g/kg, but when the dose reached to 45 g/kg, the correlation between each common peak and CK had decreased. The variation trends of correlation of spectrum-effect relationship for different dose were similar,but the correlation variation trend of the efficacy on the No. 8 peak in 33.75 g/kg group with the other four groups in the opposite, the change trends of the No. 11 peak in 22.5 g/kg group, the No. 24 peak in 33. 75 g/kg group and the No. 37 peak in 45 g/ kg group with 3.75 g/kg group and 11.25 g/kg group on the contrary. The relational orders of spectrum-effect relationship were not consistent, respectively( the first 15 peaks) :11 > 37 > 24 > 30 > 8 > 21 > 2 > 16 > 1 > 3 > 20 > 15 > 12 > 19 > 7;11 > 37 > 30 > 8 > 21 > 24 > 2 > 1 > 16 > 3 > 27 > 12 > 22 > 20 >10; 8 > 30 > 1 > 2 > 21 > 27 > 31 > 22 > 16 > 12 > 3 > 10 > 9 > 20 > 4; 1 > 2 > 27 > 21 > 31 > 22 > 12 > 16 > 9 > 3 > 10 > 4 > 17 > 30 > 20; 8 > 30 > 1 > 2 > 2 > 2 > 7 > 31 > 22 > 16 > 12 > 3 > 9 > 10 > 20 > 17.

Traditional Chinese medicines (TCMs) often contain significant levels of potentially toxic elements, including arsenic. Niu Huang Jie Du Pian pills were analyzed to determine the concentration, bioaccessibility (arsenic fraction soluble in the human gastrointestinal system) and chemical form (speciation) of arsenic. Arsenic excretion in urine (including speciation) and facial hair were studied after a one-time ingestion. The pills contained arsenic in the form of realgar, and although the total arsenic that was present in a single pill was high (28 mg), the low bioaccessibility of this form of arsenic predicted that only 4% of it was available for absorption into the bloodstream (1 mg of arsenic per pill). The species of arsenic that were solubilized were inorganic arsenate (As(V)) and arsenite (As(III)) but DMAA and MMAA were detected in urine. Two urinary arsenic excretion peaks were observed: an initial peak several (4-8) hours after ingestion corresponding to the excretion of predominantly As(III), and a larger peak at 14 h corresponding predominantly to DMAA and MMAA. No methylated As(III) species were observed. Facial hair analysis revealed that arsenic concentrations did not increase significantly as a result of the ingestion. Arsenic is incompletely soluble under human gastrointestinal conditions, and is metabolized from the inorganic to organic forms found in urine. Bioaccessible arsenic is comparable to the quantity excreted. Facial hair as a bio-indicator should be further tested

As oral contraceptive pills are available over the counter in pharmacies, pharmacists are professionally responsible for checking and informing patients about every aspect of taking these drugs. Simulated patient method is a new and robust way to evaluate professional performance of pharmacists. The aim of the present study was to evaluate the pharmacy practice of Iranian pharmacists regarding over-the-counter use of oral contraceptive pills using simulated patient method. Simulated patients visited pharmacy with a prescription containing ciprofloxacin and asked for oral contraceptive pills. The pharmacist was expected to ask important questions for using these drugs and to inform the patient about them properly. Moreover, the Pharmacists should advise patients in regard to the possible interaction. Ninety four pharmacists participated in this study. In 24 (25.3%) visits, the liable pharmacist was not present at the time of purchase. Furthermore, In 13 (18.57 %) visits by the simulated patients, the liable pharmacists did not pay any attention to the simulated patients even when they asked for consultation. Twenty nine (41.43%) pharmacists did not ask any question during dispensing. Nausea was the most frequent described side effect by pharmacists (27 (38.57%)). Yet important adverse effects of oral contraceptive pills were not mentioned by the pharmacists except for few ones. Only twelve (17.14%) pharmacists mentioned the possible interaction. There was a significant relation between the pharmacists' gender and detection of possible interaction (p value= 0.048). The quality of the pharmacists' consultations regarding the over the counter use of oral contraceptive pills was not satisfactory and required improvement.

A meta-analysis was performed to augment the insufficient data on the impact of mutative EGFR downstream phosphatidylinositol-3-kinase (PI3K) and mitogen-activated protein kinase (MAPK) pathways on the clinical efficiency of epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) treatment of non-small cell lung cancer (NSCLC) patients. Network databases were explored in April, 2015. Papers that investigated the clinical outcomes of NSCLC patients treated with EGFR-TKIs according to the status of K-ras and/or PIK3CA gene mutation were included. A quantitative meta-analysis was conducted using standard statistical methods. Odds ratios (ORs) for objective response rate (ORR) and hazard ratios (HRs) for progression-free survival (PFS) and overall survival (OS) were calculated. Mutation in K-ras significantly predicted poor ORR [OR =0.22; 95% confidence interval (CI), 0.13-0.35], shorter PFS (HR =1.56; 95% CI, 1.27-1.92), and shorter OS (HR =1.59; 95% CI, 1.33-1.91) in NSCLC patients treated with EGFR-TKIs. Mutant PIK3CA significantly predicted shorter OS (HR =1.83; 95% CI, 1.05-3.20), showed poor ORR (OR =0.70; 95% CI, 0.22-2.18), and shorter PFS (HR =1.79; 95% CI, 0.91-3.53) in NSCLC patients treated with EGFR-TKIs. K-ras mutation adversely affected the clinical response and survival of NSCLC patients treated with EGFR-TKIs. PIK3CA mutation showed similar trends. In addition to EGFR, adding K-ras and PIK3CA as routine gene biomarkers in clinical genetic analysis is valuable to optimize the effectiveness of EGFR-TKI regimens and identify optimal patients who will benefit from EGFR-TKI treatment

This group of service providers are poorly trained and have very limited knowledge about contraception. This paper investigated the nature of the advice offered to simulated current and potential users of oral contraceptive pills. The main objective was to assess the nature and quality of advice provided by PPMVs to pill users. Method: This study is based on findings from a 'mystery client' approach in which three scenarios related to contraceptive pill use were simulated. Each of the 12 mystery clients simulated one of the following three scenarios: new pill users (new to family planning or switching from condom to pills; user seeking a resupply of pills; and dissatisfied pill users intending to discontinue use. Simple random sampling was used to select 410 PPMVs from a total of 1,826 in four states in Nigeria. Qualitative study using in-depth interviews was also conducted. Results: A majority of the PPMVs had pills in stock on the day of the survey and resupplied pills to the clients. PPMVs also understood the reason and importance of referring clients who were new adopters of oral contraceptive methods to a health facility; 30% of the PPMVs referred new adopters to a health facility. However, demand from clients who do not want to go

Medication adherence is extremely important in preventing relapse and lowering symptoms in schizophrenic patients. However, estimates show that nearly half of these patients have poor adherence. The Brief Adherence Rating Scale (BARS) seems to be the most reliable tool assessing adherence in schizophrenia and shows that the antipsychotic adherence ratio (AAR) is about 49.5% in schizophrenia. The aim of the study was to test if an electronic pill dispenser named DoPill(®) improved AAR of schizophrenic patients. Furthermore, we compared AAR obtained by the DoPill(®) and the BARS, in order to verify whether the DoPill(®) provides reliable assessment of medication adherence. The DoPill(®) is a smart pill dispenser that beeps and flashes at the appropriate time of the day. Each of its 28 compartments is covered by a plastic lamina that, when taken off, sends a signal to the pharmacist. Patients were randomized to the DoPill(®) or treatment as usual groups for 6 weeks. The BARS was used as a reference measure. Forty-six percent of patients were deemed to be non-adherent with antipsychotic medication. The mean AAR was 67% after 6 weeks. DoPill(®) recorded better AAR than some of those found in the literature and were lower than the BARS estimate we found. These results suggest that DoPill(®) is a valid tool that provides more reliable and objective data for the clinician about their patient's adherence, than existing assessment tools like the BARS. Furthermore, the device may help patients successfully manage their medication regimen.

Full Text Available Many invertebrates have an unexpected nutraceutical potential and are of nutritional or ethnomedicinal significance to many tribals throughout the world. The giant pill-millipedes of the genus Arthrosphaera are traditionally used as natural medicines by tribals in the Western Ghats of India. In this study, two species of pill-millipedes (Arthrosphaera fumosa and A. magna were subjected to proximate and biochemical analysis to ascertain their nutritional potential. Bodies of A. fumosa and A. magna (after removal of their intestines had a low protein content (8-15% and high quantity of carbohydrates (40-41%. They were rich in many essential elements, especially in calcium. The essential amino acids of pillmillipedes were in high quantities. The level of glycine was the highest, followed by lysine and serine. The fatty acid methyl esters (FAMEs of males and females consist of high quantities of unsaturated fatty acids. The mono-unsaturated fatty acids were more abundant than poly-unsaturated fatty acids. Palmitic and oleic acids were dominant saturated and unsaturated fatty acids, respectively. The study has revealed for the first time that pill-millipedes of the Western Ghats of India constitute a good source of essential minerals, essential fatty acids, and essential amino acids. Being valuable contributors of organic manure by processing recalcitrant plant lignocellulosic wastes, pill-millipedes become part and parcel of organic farming as well as future nutraceutical sources.

Impact of a warning CPOE system on the inappropriate pill splitting of prescribed medications in outpatients.

Chia-Chen Hsu

Full Text Available Prescribing inappropriate pill splitting is not rare in clinical practice. To reduce inappropriate pill splitting, we developed an automatic warning system linked to a computerized physician order entry (CPOE system for special oral formulation drugs in outpatient settings. We examined the impact of the warning system on inappropriate prescribing of pill splitting and assess prescribers' responses to the warnings.Drugs with extended-release or enteric-coated formulations that were not originally intended to be split were recognized as "special oral formulations". A hard-stop system which could examine non-integer doses of drugs with special oral formulations, provide warnings to interrupt inappropriate prescriptions was integrated in CPOE in a medical center since June 2010. We designed an intervention study to compare the inappropriate splitting before and after the implementation of the warning system (baseline period 2010 January to May vs. intervention period 2010 June to 2011 August. During the intervention period, prescription changes in response to a warning were logged and analyzed.A total of 470,611 prescribed drug items with 34 different drugs with special oral formulations were prescribed in the study period. During the 15-month intervention period, 909 warnings for 26 different drugs were triggered among 354,523 prescribed drug items with special oral formulations. The warning rate of inappropriate splitting in the late intervention period was lower than those in baseline period (0.16% vs. 0.61%, incidence rate ratio 0.27, 95% CI 0.23-0.31, P<0.001. In respond to warnings, physicians had to make adjustments, of which the majority was changing to an unsplit pill (72.9%.The interruptive warning system could avoid the prescriptions with inappropriate pill splitting. Accordingly, physicians changed their behavior of prescribing special oral formulations regarding inappropriate pill splitting. We suggest the establishment of such system

Full Text Available Michel BurnierService of Nephrology and Hypertension, University Hospital, Lausanne, SwitzerlandAbstract: A majority of hypertensive patients need more than one antihypertensive drug to control their blood pressure. For this reason, most guidelines have introduced the possibility of prescribing fixed-dose combination therapies as first-line treatment in hypertension. Today, the concept of fixed-dose combinations has evolved and the term single pill combination might become more appropriate to reflect the large choice of drug combinations available on the market. Recently, a new single pill combination has been launched which combines the first direct renin inhibitor aliskiren and low doses of hydrochlorothiazide. This paper reviews the potential advantages of single pill combinations and presents the first results obtained with the aliskiren/HCTZ single pill combination in hypertension.Keywords: hypertension, drug adherence, combination therapies, diuretics, renin inhibition

Nowadays, breast disorders seriously affect women's health in an increasing number. In China, Xiaojin Pills are commonly used in the treatment of breast diseases. Doctors have concluded that the combined use of Xiaojin Pills with conventional therapy can significantly improve the efficacy with fewer side effects. However, the prescription of Xiaojin Pills is complicated and their quality control methods cannot completely ensure the quality of Xiaojin Pills. On the basis of its mechanism, our study combined chemical evaluation and biological evaluation to identify the anti-inflammatory markers of Xiaojin Pills. In this manuscript, 13 compounds in Xiaojin Pills were quantified. At the same time, the cyclooxygenase-2 inhibition rates of different Xiaojin Pills were measured and the possible markers were screened by spectrum-effect relationship. Further, anti-inflammatory activities of markers were verified and protein interaction network was analyzed, identifying the components of Protocatechuate, Beta-Boswellic acid and Levistilide A as the anti-inflammatory quality markers of Xiaojin Pills. We hope our studies can provide a scientific theoretical basis for accurately quality control of Xiaojin Pills and reasonable suggestions for pharmaceutical companies and new ideas for the quality control of other medicines.

The aim of this study was to investigate how Trichinella spiralis infection can be affected by contraceptive pills in vivo. Methods included six groups of female Wistar rats; healthy, Trichinella infected, receiving combined contraceptive pills (COCPs), receiving progestin only pills (POPs), infected receiving COCPs and infected receiving POPs. Parasite burden was measured; adult worm counts, gravidity, larvae and reproductive capacity index). Histopathological examination, immunohistochemical detection of C-kit+ mast cells and Foxp3+ T-reg. cells in intestinal sections, eosinophils muscle infiltration and CPK level were performed. Rats infected and receiving COCPs showed a significant increase in parasitic burden, and infected receiving POPs showed a significant reduction compared to infected only, with a significant increase in nongravid females (Mean total worms=964.40±55.9, 742±52.63, 686±31.68, larvae/g=5030±198.75, 2490±143.18 and 4126±152,91, respectively). Intestinal sections from infected receiving COCPs showed intact mucosa (though the high inflammatory cells infiltrate), and significant increase in C-kit+ mast cells number and intensity (30.20±4.15 and 60.40±8.29), and Foxp3+ T-reg. cells (10±1.58). Infected receiving POPs showed a significantly less CPK (5886±574.40) and eosinophilic muscle infiltration (58±13.51). Oestrogen-containing pills established a favourable intestinal environment for Trichinella by enhancing Foxp+T-reg. cells and stabilizing C-kit+mast cells, while POPs gave a potential protection with less gravidity, larval burden and eosinophilic infiltrate. © 2017 John Wiley & Sons Ltd.

The effect of Delaware law on firm value: Evidence from poison pill adoptions

Directory of Open Access Journals (Sweden)

Terry L. Campbell II

2010-07-01

Full Text Available As the leading location for firm incorporations and corporate law, Delaware occupies a unique place in corporate governance and control. In this paper, we provide fresh evidence on whether Delaware’s dominance arises from its takeover laws being in the best interest of shareholders versus managers by investigating the role of the state in which a firm is incorporated on the firm’s adoption of a poison pill. Our results indicate that announcements of adoptions of poison pills by Delaware firms are associated with returns not significantly different from those for non-Delaware firms. Moreover, Delaware firms that adopt poison pills are no more likely to receive a takeover bid, be successfully acquired, or receive better merger terms than non-Delaware firms. Overall, it appears that Delaware law, with regards to takeovers, promotes an environment consistent with a “race to the middle” philosophy, neutral to management and shareholders.

Full Text Available Background: South Delhi is one of the well developed districts in the capital with best public health care facilities. Knowledge, attitude and dispensing practices of emergency contraceptive pills (E-pills were assessed among health care providers of government dispensaries in South Delhi. Study Design: A descriptive epidemiological study. Materials and Methods: Both medical and paramedical (n = 428 providers in 63 government health care facilities were interviewed between August to December 2007 using a semi-structured interview schedule. Results: Among the different categories of the providers, medical officers were observed to be most knowledgeable about E-pills and the pharmacists were the least. The correct prescribed dose of E-pill was known only to 32% of the providers while 49% knew about its right time of intake. Misconceptions and apprehensions for promoting its use were very much prevalent even among medical officers as majority felt that open access to E-pills would increase promiscuity. The dispensing practice of providers was found positively ( P < 0.05 correlated with their knowledge. Training resulted a significant ( P < 0.05 improvement in knowledge, attitude and dispensing practice of the providers. Knowledge and training combined together contributed 35% to the dispensing practice (R 2 = 0.35. Conclusion: Besides knowledge, behavior change communication strategies should form a part of the training curricula of health care providers that would help to improve the dispensing practice of E-pills.

To investigate the therapeutic effect of the compound Danshen dripping pill combined with laser acupoint irradiation on early diabetic retinopathy, 19 patients with early diabetic retinopathy were randomly divided into a treatment group and a control group. The TaiYang, YangBai, YuYao and ZanZhu acupoints of patients in the treatment group were irradiated with a semiconductor laser combined with the oral compound Danshen dropping pills, while those in the control group only used the oral compound Danshen dropping pills. The indicators of vision, mean defect of light sensitivity in the visual field, renal function and fasting blood glucose, were examined to evaluate the efficacy. After treatment, the above indicators of patients in the two groups were significantly improved and there was a significant difference between the two groups. This showed that the compound Danshen dripping pills combined with the laser acupoint irradiation can improve the ischemic and anoxic state of early diabetic retinopathy and improve the visual field.

Full Text Available Suxiao jiuxin pill is considered an effective ancillary drug in patients with coronary heart disease. Although numerous small, single-center clinical trials have been conducted, the benefits and harms of suxiao jiuxin pill remain controversial. We performed a meta-analysis to clarify the efficacy of suxiao jiuxin pill on patients with coronary heart disease. Randomized controlled trials were identified by using the Cochrane Library, PubMed, Web of Science, Embase, Wanfang, Weipu, and China Knowledge Resource Integrated databases (until June 2016. Pooled relative risks (RR, weighted mean differences (WMD, and 95% confidence intervals (95% CIs were estimated using random-effects models. Forty-one trials involving 6276 patients were included in our analysis. Administration of suxiao jiuxin pill significantly improved electrocardiogram (ECG results when compared with other therapies (RR 1.32, 95% CI 1.26 to 1.38, and P<0.001. Subgroup analyses revealed that suxiao jiuxin pills improve ECG results more than salvia tablets (RR 1.54, 95% CI 1.41 to 1.67, and P<0.001, isosorbide dinitrate (RR 1.14, 95% CI 1.21 to 1.44, and P=0.001, nitroglycerin (RR 1.35, 95% CI 1.16 to 1.56, and P<0.001, and other drugs (RR 1.32, 95% CI 1.21 to 1.44, and P<0.001. Available evidence additionally suggests that suxiao jiuxin pills could significantly reduce total cholesterol (WMD −0.62 mmol/L, 95% CI −1.06 to –0.18 mmol/L, and P=0.005 and low-density lipoprotein (LDL levels (WMD −1.12 mmol/L, 95% CI −1.42 to −0.82 mmol/L, and P<0.001 and increase high-density lipoprotein (HDL levels (WMD 0.32 mmol/L, 95% CI 0.07 to 0.58 mmol/L, and P=0.014. However, no significant differences were observed in total triglyceride levels, plasma viscosity, hematocrit, and fibrinogen. No incidences of adverse reactions were observed after administration of suxiao jiuxin pill. Improvements in ECG results and lipid profiles were also observed after suxiao jiuxin

Background The frequency rates of mutations such as KRAS, NRAS, BRAF, and PIK3CA in colorectal cancer (CRC) differ among populations. The aim of this study was to assess mutation frequencies in the Arab population and determine their correlations with certain clinicopathological features. Methods Arab patients from the Arab Gulf region and a population of age- and sex-matched Western patients with CRC whose tumors were evaluated with next-generation sequencing (NGS) were identified and retrospectively reviewed. The mutation rates of KRAS, NRAS, BRAF, PIK3CA, TP53, and APC were recorded, along with clinicopathological features. Other somatic mutation and their rates were also identified. Fisher’s exact test was used to determine the association between mutation status and clinical features. Results A total of 198 cases were identified; 99 Arab patients and 99 Western patients. Fifty-two point seven percent of Arab patients had stage IV disease at initial presentation, 74.2% had left-sided tumors. Eighty-nine point two percent had tubular adenocarcinoma and 10.8% had mucinous adenocarcinoma. The prevalence rates of KRAS, NRAS, BRAF, PIK3CA, TP53, APC, SMAD, FBXW7 mutations in Arab population were 44.4%, 4%, 4%, 13.1%, 52.5%, 27.3%, 2% and 3% respectively. Compared to 48.4%, 4%, 4%, 12.1%, 47.5%, 24.2%, 11.1% and 0% respectively in matched Western population. Associations between these mutations and patient clinicopathological features were not statistically significant. Conclusions This is the first study to report comprehensive hotspot mutations using NGS in Arab patients with CRC. The frequency of KRAS, NRAS, BRAF, TP53, APC and PIK3CA mutations were similar to reported frequencies in Western population except SMAD4 that had a lower frequency and higher frequency of FBXW7 mutation.

Wilkins, Chris; Sweetsur, Paul

2010-01-01

'Party' pills containing benzylpiperazine (BZP) and trifluoromethylphenylpiperazine (TFMPP) were sold legally in New Zealand until early 2008. Prospective studies of hospital emergency department admissions appeared to suggest that the harm from party pills was greater among South Island than North Island users. The party pill industry association (the Social Tonics Association of New Zealand or STANZ) claimed these differences were due to the voluntary code of practice adopted by their members in the North Island. The aims of this study were to examine differences in harm from party pills between North and South Island users in New Zealand, and to investigate possible reasons for any differences in harm, including the impact of industry self-regulation. A national household survey of BZP/TFMPP party pill use was conducted in New Zealand. Information on the ingredients of party pills was provided by the National Poisons Centre. In a number of instances last year users of party pills from the South Island were more likely than last year users from the North Island to report harm from party pills. There were no differences between the North and South Island users with regard to the mean number of BZP/TFMPP party pills taken, mean total milligrams of BZP/TFMPP ingested or prevalence of use of other drug types in combination with party pills. A minority of users in the South Island reported using extremely high numbers of BZP/TFMPP party pills in a single session and using extremely high potency brands of party pills. Last year party pill users from the South Island were more likely than those from the North Island to be students. A number of factors may have contributed to the greater harm from BZP/TFMPP party pills among South Island users including a higher proportion of student users with higher consumption of alcohol and other drugs. Users from both Islands commonly exceeded the dosage of BZP/TFMPP recommended by STANZ suggesting the STANZ code of conduct was

60 Co γ-ray irradiation and epoxy-ethane treatment were used to sterilize the cardiac pill. The results showed that 60 Co γ-ray irradiation with the dosage of 4350-13050 Gy was more effective, while the epoxy-ethane treatment was not. By analyzing the sample, the bacterial number in cardiac pill treated with epoxy-ethane was more than 10,000 cells/g. The cardiac pill, however, sterilized by 60 Co γ-ray was only 0-600 cells/g, which completely correspond to the national bacteral inspect standard. In this treatment, the pharmacological analysis was done with white mice and rabbits raised with irradiated cardiac pill. The results showed that there was no abnormality in the persistence of the cardiac muscle to anemia and resistance to abnormal rhythm of the heart

In this study, we aimed to establish a comprehensive and practical quality evaluation system for Shenmaidihuang pills. A simple and reliable high-performance liquid chromatography coupled with photodiode array detection method was developed both for fingerprint analysis and quantitative determination. In fingerprint analysis, relative retention time and relative peak area were used to identify the common peaks in 18 samples for investigation. Twenty one peaks were selected as the common peaks to evaluate the similarities of 18 Shenmaidihuang pills samples with different manufacture dates. Furthermore, similarity analysis was applied to evaluate the similarity of samples. Hierarchical cluster analysis and principal component analysis were also performed to evaluate the variation of Shenmaidihuang pills. In quantitative analysis, linear regressions, injection precisions, recovery, repeatability and sample stability were all tested and good results were obtained to simultaneously determine the seven identified compounds, namely, 5-hydroxymethylfurfural, morroniside, loganin, paeonol, paeoniflorin, psoralen, isopsoralen in Shenmaidihuang pills. The contents of some analytes in different batches of samples indicated significant difference, especially for 5-hydroxymethylfurfural. So, it was concluded that the chromatographic fingerprint method obtained by high-performance liquid chromatography coupled with photodiode array detection associated with multiple compounds determination is a powerful and meaningful tool to comprehensively conduct the quality control of Shenmaidihuang pills. © 2016 WILEY-VCH Verlag GmbH & Co.

2018-05-01

In the current study, gas chromatography-mass spectrometry (GC-MS) fingerprinting of herbal slimming pills assisted by chemometric methods has been presented. Deconvolution of two-way chromatographic signals of nine herbal slimming pills into pure chromatographic and spectral patterns was performed. The peak clusters were resolved using multivariate curve resolution-alternating least squares (MCR-ALS) by employing appropriate constraints. It was revealed that more useful chemical information about the composition of the slimming pills can be obtained by employing sophisticated GC-MS method coupled with proper chemometric tools yielding the extended number of identified constituents. The thorough fingerprinting of the complex mixtures proved the presence of some toxic or carcinogen components, such as toluene, furfural, furfuryl alcohol, styrene, itaconic anhydride, citraconic anhydride, trimethyl phosphate, phenol, pyrocatechol, p-propenylanisole and pyrogallol. In addition, some samples were shown to be adulterated with undeclared ingredients, including stimulants, anorexiant and laxatives such as phenolphthalein, amfepramone, caffeine and sibutramine.

Cancer is one of the main public health issues in the world. Breast cancer is one of the most common types of cancer among women. It is also the second cause of mortality in women. The association between the use of oral contraceptive pills and breast cancer is controversial and a main issue in public health. Some findings have shown that taking these pills does not have a significant effect in increasing the risk of breast cancer, while others have confirmed the carcinogenic effect of these products. These contradictory findings necessitated this meta-analysis, through of all correlated studies in Iran. All published studies were considered from June 2000 until June 2015, using reliable Latin databases like PubMed, Google Scholar, Google search, Scopus, and Science Direct, and Persian database like SID, Irandoc, IranMedex, and Magiran. Finally, 26 papers were selected: 24 studies were case control while two were population based studies. A total of 26 papers with 46,260 participants were assessed since 2001. Overall estimate of OR for the effect of oral contraceptive pills on breast cancer is 1.521 (CI = 1.25-1.85), which shows that the intervention group had more chance (52%) compared to the control group ( P = 0.001). Using these pills increased the risk of breast cancer up to 1.52 times. Because of directly increasing levels of estrogen and the role of estrogen in gaining weight indirectly, oral contraceptive pills can stimulate the occurrence of breast cancer. More studies should be conducted for controlling the period of pill use.

Background Oral contraceptive pills (OCPs) are one of the most reliable methods of contraception. However, lack of knowledge about oral contraceptive use and inconsistent pill-taking might result in decreased efficacy. The study reported here aimed to explore women’s knowledge about oral contraceptive use and assess the factors associated with knowledge about OCPs among users. Methods This cross-sectional survey was conducted at King Abdulaziz University Hospital, Jeddah, Saudi Arabia between April and June 2014. We included married, non-pregnant women >18 years old who had used a combined 21-day OCP for at least 3 months prior to recruitment. A questionnaire was used to collect the participants’ demographic information. It also assessed their knowledge about OCPs. Data were entered into and analyzed using SPSS software. Results A total of 357 women were recruited. Of these, 57.7% reported they knew what to do after missing one or two pills, but only 18.3% knew exactly what to do after missing more than two pills consecutively. Postgraduate women had a significantly higher knowledge score than illiterate women (P=0.002) and those who had completed at least primary education (P=0.001). Conversely, there was no difference in knowledge scores between Saudi and expatriate women (P=0.2). Monthly incomes (P=0.2) and mode of OCP selection (P=0.2) were also not significantly associated with knowledge scores. Conclusion Women had poor knowledge about OCP use. Appropriate measures should be taken to educate women about proper oral contraceptive use. PMID:25792813

This study aimed to determine design features of a drug-checking service that would be feasible, attractive and likely to be used by Australian festival and nightlife attendees. Web survey of 851 Australians reporting use of psychostimulants and/or hallucinogens and attendance at licensed venues past midnight and/or festivals in the past year (70% male; median age 23 years). A drug-checking service located at festivals or clubs would be used by 94%; a fixed-site service external to such events by 85%. Most (80%) were willing to wait an hour for their result. Almost all (94%) would not use a service if there was a possibility of arrest, and a majority (64%) would not use a service that did not provide individual feedback of results. Drug-checking results were only slightly more attractive if they provided comprehensive quantitative results compared with qualitative results of key ingredients. Most (93%) were willing to pay up to $5, and 68% up to $10, per test. One-third (33%) reported willingness to donate a whole dose for testing: they were more likely to be male, younger, less experienced, use drugs more frequently and attend venues/festivals less frequently. In this sample, festival- or club-based drug-checking services with low wait times and low cost appear broadly attractive under conditions of legal amnesty and individualised feedback. Quantitative analysis of ecstasy pills requiring surrender of a whole pill may appeal to a minority in Australia where pills are more expensive than elsewhere.

Background and Objective : Contraceptive pills are generally taken orally and can cause side effects such as nausea, vomiting and hypertension. The vaginal use of these pills can reduce such complications. Our objective was to compare the efficacy and side effects of low dose contraceptive pills by oral and vaginal route in the management of dysfunctional uterine bleeding-(DUB) Methods: This comparative observational study was conducted at Beheshti and Alzahra (SA) teaching hospitals, affiliated to Isfahan University of Medical Sciences in 2010-2011. One hundred women who presented with DUB were randomly assigned into two groups of equal number, receiving the low dose oral contraceptive pills by oral or vaginal route for three month. The amount and duration of bleeding were compared at the beginning and at the end of the study and side effects by these two methods compared. The results of this study showed that both oral and vaginal routes effectively reduced the duration and amount of bleeding due to DUB after three courses of treatment. This effect was better in the vaginal method compared with oral administration (P = 0.03). Regarding the side effects, nausea and vomiting were significantly higher in the oral group than in the vaginal group (P = 0.03). Vulvovaginitis infection was more frequent in the vaginal group than in the oral group (P = 0.03). Low dose contraceptive pills are effective in reducing the amount, time, and duration of bleeding in patients with DUB. In addition, reduction of gastrointestinal side effects by vaginal route helps to use these pills by the patient with proper training of physicians, midwives and patients.

Therapies that efficiently induce apoptosis are likely to be required for durable clinical responses in patients with solid tumors. Using a pharmacological screening approach, we discovered that the combined inhibition of BCL-XL and the mTOR/4E-BP axis results in selective and synergistic induction of apoptosis in cellular and animal models of PIK3CA mutant breast cancers, including triple negative tumors. Mechanistically, inhibition of mTOR/4E-BP suppresses MCL-1 protein translation only in ...

Design and performance of a fast thermal response miniature Chromium Potassium Alum (CPA) salt pill for use in a millikelvin cryocooler

Bartlett, J.; Hardy, G.; Hepburn, I. D.

2015-01-01

The design and performance of a fast thermal response miniature (24 mm outer diameter by 30 mm long) Chromium Potassium Alum (CPA) salt pill is described. The need for a fast thermal response has been driven by the development of a continuously operating millikelvin cryocooler (mKCC) which uses 2 T superconducting magnets that can be ramped to full field in 30 s. The consequence of magnetising and demagnetising the CPA pill in such a short time is that thermal boundary resistance and eddy current heating have a significant impact on the performance of the pill, which was investigated in detail using modelling. The complete design of a prototype CPA pill is described in this paper, including the methods used to minimise thermal boundary resistance and eddy current heating as well as the manufacturing and assembly processes. The performance of the prototype CPA pill operated from a 3.6 K bath is presented, demonstrating that a complete CPA cycle (magnetising, cooling to bath and demagnetising) can be accomplished in under 2.5 min, with magnetisation and demagnetisation taking just 30 s each. The cold finger base temperature of the prototype varies with demagnetisation speed as a consequence of eddy current heating; for a 30 s demagnetisation, a base temperature of 161 mK is obtained, whilst for a 5 min demagnetisation, a base temperature of 149 mK was measured (both from a 3.6 K and 2 T starting position). The measured hold times of the CPA pill at 200 mK, 300 mK, and 1 K are given, proving that the hold time far exceeds the recycle time and demonstrating the potential for continuous operation when two ADRs are used in a tandem configuration. The ease and speed at which the CPA pill temperature can be changed and controlled when stepping between operating temperatures in the range of 200 mK to 4 K using a servo control program is also shown, once again highlighting the excellent thermal response of the pill. All of the test results are in good agreement with the

Full Text Available The PIK3C3 locus was implicated in case-case genome-wide association study of systemic lupus erythematosus (SLE which we had performed to detect genes associated with autoantibodies and serum interferon-alpha (IFN-α. Herein, we examine a PIK3C3 promoter variant (rs3813065/-442 C/T in an independent multiancestral cohort of 478 SLE cases and 522 controls. rs3813065 C was strongly associated with the simultaneous presence of both anti-Ro and anti-Sm antibodies in African-American patients [OR=2.24 (1.34–3.73, P=2.0×10−3]. This autoantibody profile was associated with higher serum IFN-α (P=7.6×10−6. In the HapMap Yoruba population, rs3813065 was associated with differential expression of ERAP2 (P=2.0×10−5, which encodes an enzyme involved in MHC class I peptide processing. Thus, rs3813065 C is associated with a particular autoantibody profile and altered expression of an MHC peptide processing enzyme, suggesting that this variant modulates serologic autoimmunity in African-American SLE patients.

Men’s aspirations shift away from teaching towards occupations that are associated with higher average...

'Worth the test?' Pragmatism, pill testing and drug policy in Australia.

Science.gov (United States)

Groves, Andrew

2018-04-10

Recent deaths of young Australian music festival attendees from 'party-drug' overdoses have sparked debate about the effectiveness of drug policies. Australia is widely lauded for its harm minimisation approach to drugs, and yet, over the last 30 years, it can be argued its policies have been fragmented, sometimes inconsistent and contradictory. The present article examines the root of this inconsistency, using it as a foundation to advocate for drug policy reform. In keeping with the goals of the National Drug Strategy to promote policy innovation, there is an opportunity to learn from international studies which have shown promising findings in the reduction of party-drug use and its harms through application of pill testing. This paper evaluates Australia's National Drug Strategy and pill testing through a lens of pragmatism, to determine whether there is space for testing practices in contemporary policy. Specifically, the paper analyses current drug policy literature and research studies, examining a range of key drug use indicators, social and political debate and research evidence. The need for policy reform, attitudinal and cultural shifts and development of stronger cross-sectoral partnerships is highlighted, to ensure a rational and logical approach that genuinely tackles drug policy-making and strategy from a broad public health perspective. Using a theoretical frame of pragmatism and drawing from national and international research evidence, this paper recommends the integration of pill testing into Australia's harm minimisation strategy.

To examine the use of contraception at last sexual intercourse among currently sexually active adolescents. We analyzed data from national school-based Youth Risk Behavior Surveys (YRBS) conducted in 1991, 1993, 1995, and 1997. The YRBS is a self-administered, anonymous survey which uses a national probability sample of U.S. students in public and private schools from grades 9 through 12.

The low frequency of survival of stem cells implanted in the myocardium after acute myocardial infarction may be caused by inflammation and oxidative stress in the myocardial microenvironment. We evaluated the effects of a traditional Chinese medicine, Compound Danshen Dripping Pills, on the cardiac microenvironment and cardiac function when used alone or in combination with human umbilical cord blood mononuclear cell transplant after acute myocardial infarction. After surgically induced acute myocardial infarction, rabbits were treated with Compound Danshen Dripping Pills alone or in combination with human umbilical cord blood mononuclear cell transplant. Evaluation included histology, measurement of left ventricular ejection fraction and fractional shortening, leukocyte count, count of green fluorescent protein positive cells, superoxide dismutase activity, and malondialdehyde content. Combination treatment with Compound Danshen Dripping Pills and human umbilical cord blood mononuclear cell transplant significantly increased the survival of implanted cells, inhibited cardiac cell apoptosis, decreased oxidative stress, decreased the inflammatory response, and improved cardiac function. Rabbits treated with either Compound Danshen Dripping Pills or human umbilical cord blood mononuclear cells alone had improvement in these effects compared with untreated control rabbits. Combination therapy with Compound Danshen Dripping Pills and human umbilical cord blood mononuclear cells may improve cardiac function and morphology after acute myocardial infarction.

To study the effect of compound Danshen dripping pills and atorvastatin on restenosis after abdominal aorta angioplasty in rabbits. Rabbit models of abdominal aorta restenosis after angioplasty were established and treated with saline (group A), compound Danshen dripping pills (group B), atorvastatin (group C), or compound Danshen dripping pills plus atorvastatin (group D). HE staining was used to determine the thickness of arterial intimal hyperplasia and assess the morphological changes of the narrowed artery. Immunohistochemistry was employed to detect the expression of nuclear factor-κB (NF-κB) and monocyte chemoattractant protein-1 (MCP-1). Compared with group A, the 3 treatment groups showed significant increased vascular cavity area and reduced intimal area and percentage of intimal hyperplasia (Ppills combined with atorvastatin produces better effects than the drugs used alone in inhibiting vascular smooth muscle cell proliferation in rabbits after abdominal aorta angioplasty possibly due to a decreased expression of MCP-1 as a result of NF-κB inhibition.

Cloxacillin: A New Cause of Pill-Induced Esophagitis

Full Text Available A large variety of medications can cause pill-induced esophagitis. Herein we present a case of cloxacillin-induced esophagitis. A 66-year-old male presented with an acute onset of epigastric and retrosternal pain on the 5th day of a course of oral cloxacillin prescribed for erysipelas. Initial clinical and imaging assessment was negative and he was sent home. A few days later, he returned with persistent severe retrosternal pain; endoscopy at the same day revealed a normal upper esophagus, several small stellate erosions in the midesophagus, and a normal squamocolumnar junction with a small hiatus hernia. Treatment with esomeprazole 40 mg bid and MucaineR suspension resulted in complete resolution of his symptoms. Pill-induced esophagitis may be underreported by patients, when symptoms are mild and unrecognized and/or underdiagnosed by the clinicians as a cause of retrosternal pain, odynophagia, or dysphagia. Failure of early recognition may result in unnecessary diagnostic investigations and prolongation of the patient’s discomfort. This case signifies the importance of enhancing clinician awareness for drug-associated esophageal injury when assessing patients with retrosternal pain, as well as the value of prophylaxis against this unpleasant condition by universally recommending drinking enough water in an upright position during ingestion of any oral medication.

Seasonal occurrence and activity of endemic pill millipedes ( Arthrosphaera magna) were examined in organically managed mixed plantation and semi-evergreen forest reserve in southwest India between November 1996 and September 1998. Abundance and biomass of millipedes were highest in both habitats during monsoon season. Soil moisture, conductivity, organic carbon, phosphate, potassium, calcium and magnesium were higher in plantation than in forest. Millipede abundance and biomass were about 12 and 7 times higher in plantation than in forest, respectively ( P 0.05). Millipede abundance and biomass were positively correlated with rainfall ( P = 0.01). Besides rainfall, millipedes in plantation were positively correlated with soil moisture as well as temperature ( P = 0.001). Among the associated fauna with pill millipedes, earthworms rank first followed by soil bugs in both habitats. Since pill millipedes are sensitive to narrow ecological changes, the organic farming strategies followed in mixed plantation and commonly practiced in South India seem not deleterious for the endangered pill millipedes Arthrosphaera and reduce the risk of local extinctions.

This study investigated sociological factors that may influence women's utilization of and adherence to oral contraceptive pills. This was a retrospective cross-sectional study using the 2010-2012 Medical Expenditure Panel Survey. Female adults aged 18-50 years were included. Logistic regression was performed to discern women's decisions to use oral contraceptive pills or not. Ordinary least squares and Poisson regressions were conducted to examine the number of oral contraceptive pills received, refill frequency, and annual out-of-pocket expenditure on oral contraceptive pills. Covariates were based on the Andersen model of health care utilization. Among the study sample (weighted n = 207,007,531), 14.8% were oral contraceptive pill users. Factors positively related to oral contraceptive pill use included non-Hispanic white ethnicity, younger age, not currently married, having private insurance, residing in the Midwest, higher education level, and higher annual family income. Being non-Hispanic white and having a higher education level were positively related to oral contraceptive pill adherence. Our findings therefore demonstrate disparities in oral contraceptive pill utilization and adherence, especially according to women's race/ethnicity and educational level. This study serves as a baseline assessment for the impact of the Affordable Care Act on oral contraceptive pill utilization and adherence for future studies. © The Author(s) 2015.

Smart pills were originally developed for diagnosis; however, they are increasingly being applied to therapy - more specifically drug delivery. In addition to smart drug delivery systems, current research is also looking into localization systems for reaching the target areas, novel locomotion mechanisms and positioning systems. Focusing on the major application fields of such devices, this article reviews smart pills developed for local drug delivery. The review begins with the analysis of the medical needs and socio-economic benefits associated with the use of such devices and moves onto the discussion of the main implemented technological solutions with special attention given to locomotion systems, drug delivery systems and power supply. Finally, desired technical features of a fully autonomous robotic capsule for local drug delivery are defined and future research trends are highlighted.

Objective To estimate the effect of progestin-only vs. combined hormonal contraceptive pills on rates of breastfeeding continuation in postpartum women. Secondary outcomes include infant growth parameters, contraceptive method continuation and patient satisfaction with breastfeeding and contraceptive method. Methods In this randomized controlled trial, postpartum breastfeeding women who desired oral contraceptives were assigned to progestin-only vs. combined hormonal contraceptive pills. At two and eight weeks postpartum, participants completed in-person questionnaires that assessed breastfeeding continuation and contraceptive use. Infant growth parameters including weight, length and head circumference were assessed at eight weeks postpartum. Telephone questionnaires assessing breastfeeding, contraceptive continuation and satisfaction were completed at 3-7 weeks and 4 and 6 months. Breastfeeding continuation was compared between groups using Cox proportional hazards regression. Differences in baseline demographic characteristics and in variables between the two intervention groups were compared using chi-square tests, Fisher’s Exact test, or two-sample t-tests as appropriate. Results Breastfeeding continuation rates, contraceptive continuation, and infant growth parameters did not differ between users of progestin-only and combined hormonal contraceptive pills. Infant formula supplementation and maternal perception of inadequate milk supply were associated with decreased rates of breastfeeding in both groups. Conclusions Choice of combined or progestin-only birth control pills administered two weeks postpartum did not adversely affect breastfeeding continuation. PMID:22143258

Radiolysis of bilirubin and cholic acids (cholic acid, desoxycholic acid and lithocholic acid) in hydrous pellet have been investigated with following parameters, which were hydrous content, radiation dose and the dose rate, to discuss the application of gamma -irradiation for sterilization of crude drug pill involving bezoar bovis. At 774 C/kg(3.0MR) irradiation for 5% and 10% hydrous contents pellets, the radiolysis percent of those components were less than 5%. However, the higher hydrous pellet, the radiolysis percents of those are more increase. At the same irradiated condition for 20% hydrous contents pellets, the radiolysis percents of those were 15--22%. The hydrous percent of commercial crude drug pill involving bezoar bovis are about 9%, so that the radiolysis of those components will be less than 5% on the sterilization. The radiolysis percent of bilirubin are constant to variation of radiation dose rate between 51.6--722.5C/kg.hr(0.2--2.8MR/hr). But, the values of cholic acids don't definite such as that of bilirubin, because of larger analitycal error. (author)

Measurements of the effective lifetimes in the $B_{s}^{0} \\rightarrow K^{+}K^{-}$, $B^{0} \\rightarrow K^{+}\\pi^{-}$ and $B_{s}^{0} \\rightarrow \\pi^{+}K^{-}$ decays are presented using $1.0~\\mathrm{fb^{-1}}$ of $pp$ collision data collected at a centre-of-mass energy of 7 TeV by the LHCb experiment. The analysis uses a data-driven approach to correct for the decay time acceptance. The measured effective lifetimes are $\\tau_{B_{s}^{0} \\rightarrow K^{+}K^{-}}$ = $1.407~\\pm~0.016~\\pm~0.007~\\mathrm{ps}$, $\\tau_{B^{0} \\rightarrow K^{+}\\pi^{-}}$ = $1.524~\\pm~0.011~\\pm~0.004~\\mathrm{ps}$, $\\tau_{B_{s}^{0} \\rightarrow \\pi^{+}K^{-}}$ = $1.60~\\pm~0.06~\\pm~0.01~\\mathrm{ps}$. This is the most precise determination to date of the effective lifetime in the $B_{s}^{0} \\rightarrow K^{+}K^{-}$ decay and provides constraints on contributions from physics beyond the Standard Model to the $B_{s}^{0}$ mixing phase and the width difference $\\Delta\\Gamma_{s}$.

Feminism, biomedicine and the 'reproductive destiny' of women in clinical texts on the birth control pill.

Science.gov (United States)

Carson, Andrea

2018-07-01

The birth control pill is one of the most popular forms of contraception in North America and has been a key player in women's rights activism for over 50 years. In this paper, I conduct a feminist deconstructive analysis of 12 biomedical texts on the birth control pill, published between 1965 and 2016. This study is situated amongst the feminist scholarship that challenges the representation of women's bodies in biomedicine. Findings suggest that clinical texts on the birth control pill continue to universalise women's lives and experiences, and essentialise them based on their reproductive capacities. One way the texts accomplish this is by making women absent or passive in the literature thereby losing concern for the diversity of their lives, interpretations and identities as more than reproductive beings. The consequence of such representations is that biomedical texts disseminate limited forms of knowledge, in particular concerning definitions of 'natural' and 'normal' behaviour, with important consequences for the embodied experiences of women.

Dietary supplements based on hepatoprotective plants have been increasingly used in the prevention of liver injuries. In the present work, the aim was to study the phenolic profile and possibly relate it to the in vitro antimicrobial activity of two different formulations (pills and syrups) of artichoke and milk thistle, the antioxidant and anti-hepatocellular carcinoma activities of which were previously reported by our research group. The phenolic profiles were obtained by HPLC-DAD-ESI/MS, and the antimicrobial activity evaluation was performed with the clinical isolates of multiresistant bacteria (Escherichia coli, extended spectrum β-lactamases (ESBL) producing Escherichia coli, Proteus mirabilis, methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa). Artichoke syrup revealed the presence of vanillic acid and luteolin-7-O-glucoside while the pills possessed higher concentrations of 4-O-caffeoylquinic, 5-O-caffeoylquinic and 1,3-O-dicaffeoylquinic acids, this latest being able to inhibit the growth of MRSA. Regarding milk thistle formulations, the syrup presented isorhamnetin-O-deoxyhexoside-O-dihexoside, isorhamnetin-O-deoxyhexoside-O-hexoside and isorhamnetin-3-O-rutinoside as the major phenolic constituents whereas the pills were richer in taxifolin, silymarin derivatives and hydroxylated silibinin; the syrup revealed antimicrobial activity against all the studied bacteria with the exception of Proteus mirabilis whereas the pills revealed activity against ESBL producing Escherichia coli. Overall, all of the studied formulations revealed to be a good source of phenolic compounds, among which milk thistle syrup presented the highest variety and concentration of flavonoids, which is possibly related to its strongest antimicrobial activity.

The use of breastfeeding as a method of birth spacing occasionally ends in "unplanned pregnancy." This is due to unexpected expiration of one or more of the lactation amenorrhea method (LAM) prerequisites. The current study tests a new concept that the in-advance provision of single packet of progestogen emergency contraception (EC) pills during the postpartum LAM counseling may decrease the incidence of unplanned pregnancy during breastfeeding. This was a registered two-armed randomized controlled trial (NCT 01111929). Women intending to breastfeed and to postpone pregnancy for 1 year or more were approached. They received adequate postpartum contraceptive counseling. Women intending to use LAM were randomly assigned to one of two groups. The LAM-only group received the proper LAM counseling and did not receive counseling about EC. The LAM-EC group received counseling for both LAM and EC with in-advance provision of one packet of EC pills. They were advised to use these pills if one of the prerequisites of LAM expires and sexual relation has occurred before the initiation of another regular contraceptive protection. All the participants were advised that they need to use another regular method upon expiration of any of the LAM prerequisites. Eligible women were 1158 parturients randomized into two equal groups. Forty-four percent of the women provided with EC used them. Significantly more women in the LAM-EC group initiated regular contraception within or shortly after the first 6 months postpartum when compared with those in the LAM-only group (30.5% vs. 7.3%, respectively; p=.0004). Pregnancy occurred in 5% of the LAM-only group as compared with 0.8% in the LAM-EC group (p=.005). Minimal side effects were reported after EC use. In-advance provision of EC pills can increase the rate of initiation of regular contraception once one or more of the prerequisites of LAM expire. Consequently, the use of EC pills as a temporary backup of LAM can decrease the incidence

Administering drugs as fixed-dose combinations (FDCs) versus the same active drugs administered as separate pills is assumed to enhance treatment adherence. We synthesized evidence from randomized controlled trials (RCTs) about the effect of FDCs versus separate pills on adherence. We searched PubMed for RCTs comparing a FDC with the same active drugs administered as separate pills, including a quantitative estimate of treatment adherence, without restriction to medical condition. The odds ratio (OR) of optimal adherence with FDCs versus separate pills was used as common effect size and aggregated into a pooled effect estimate using a random effect model with inverse variance weights. Out of 1258 articles screened, only six studies fulfilled inclusion criteria. Across medical conditions, administering drugs as FDC significantly increased the likelihood of optimal adherence (OR 1.33 (95% CI, 1.03-1.71)). Within subgroups of specific medical conditions, the favourable effect of FDCs on adherence was of borderline statistical significance for HIV infection only (OR 1.46 (95% CI, 1.00-2.13)). We observed a remarkable paucity of RCTs comparing the effect on adherence of administering drugs as FDC versus as separate pills. Administering drugs as FDC improved medication adherence. However, this conclusion is based on a limited number of RCTs only.

Full Text Available The species-rich giant pill-millipedes (Sphaerotheriida often represent a microendemic component of Madagascar’s mega-invertebrate fauna. Of the chirping genus Sphaeromimus de Saussure & Zehntner, 1902, ten species have been described. Here, we describe two new species of Sphaeromimus integratively, combining light microscopy, scanning electron microscopy, DNA barcoding and micro-CT technology for the first time in a taxonomic description of a giant pill-millipede. S. kalambatritra sp. nov. and S. midongy sp. nov. are the first giant pill-millipedes collected and described from the mountainous rainforests of Kalambatritra and Midongy. Both species show island gigantism compared to their congeners. Our analysis of the mitochondrial COI gene shows that the two species are related to one another with a moderate genetic distance (9.4%, while they are more closely related to an undetermined specimen from the forest of Vevembe (6.3% and 8.4%. They stand in a basal position with S. ivohibe Wesener, 2014 and S. musicus (de Saussure & Zehntner, 1897. The four aforementioned species share a high number of stridulation ribs on the male harp. Our micro-CT analysis provides a look into the head of S. kalambatritra sp. nov. and shows that non-destructive CT methods are a useful tool for studying the inner morphology of giant pill-millipedes.

Dragon's blood is a bright red resin obtained from Dracaena cochinchinensis (Lour.) S.C.Chen (Yunnan, China). As a traditional Chinese medicinal herb, it has great traditional medicinal value and is used for wound healing and to stop bleeding. Its main biological activity comes from phenolic compounds. In this study, phenolic compounds were made into dropping pills and their protective effects were examined by establishing focal cerebral ischemia rats model used method of Middle Cerebral Artery Occlusion (MCAO), and by investigating indexes of neurological scores, infarct volume, cerebral index, cerebral water content and oxidation stress. Compared to model group, high, middle and low groups of Dragon's blood dropping pills could improve the neurological function significantly (ppills had protective effects on focal cerebral ischemia rats.

'Stratified Contraception': Emergency Contraceptive Pills and Women's Differential Experiences in Contemporary India.

Science.gov (United States)

Sheoran, Nayantara

2015-01-01

Available without prescriptions in India since 2005, emergency contraceptive pills (ECPs) and their advertisements have provided women with increased contraceptive options and a vocabulary to talk about their reproductive lives. I draw on long-term fieldwork with women in urban India about ECPs, demonstrating a new form of 'stratified contraception' enabled by these pills and their advertisements. I posit that there are within India spaces that replicate the luxuries and privileges of the global North. These material conditions, I suggest, are replicated when it comes to contraception as there are hubs of women consumers of contraception and contraceptive advertising that participate in an 'imagined cosmopolitanism' within the global South in close proximity to 'contraceptive ghettos.' Moving beyond simplistic binaries, I outline three major stratifications along which women experience this medical technology and outline the implications for women and their contraceptive choices when notions of northern privilege exist in the 'South.'

Reaching the end of the line: Operational issues with implementing phone-based unannounced pill counts in resource-limited settings.

Directory of Open Access Journals (Sweden)

Full Text Available Accurate measurement of adherence is necessary to ensure that therapeutic outcomes can be attributed to the recommended treatment. Phone-based unannounced pill counts were shown to be feasible and reliable measures of adherence in developed settings; and have been further used as part of medication adherence interventions. However, it is not clear whether this method can be implemented successfully in resource-limited settings, where cellular network and mobile phone coverage may be low. Our objective is to describe operational issues surrounding the use of phone-based unannounced pill counts in Lesotho and Ethiopia.Phone-based monthly unannounced pill counts, using an adaptation of a standardized protocol from previous US-based studies, were utilized to measure anti-TB and antiretroviral medication adherence in two implementation science studies in resource-limited settings, START (Lesotho and ENRICH (Ethiopia.In START, 19.6% of calls were completed, with 71.9% of participants reached at least once; majority of failed call attempts were due to phones not being available (54.8% or because participants were away from the pills (32.7%. In ENRICH, 33.5% of calls were completed, with 86.7% of participants reached at least once; the main reasons for failed call attempts were phones being switched off (31.5%, participants not answering (27.3%, participants' discomfort speaking on the phone (15.4%, and network problems (13.2%. Structural, facility-level, participant-level, and data collection challenges were encountered in these settings.Phone-based unannounced pill counts were found to be challenging, and response rates suboptimal. While some of these challenges were specific to local contexts, most of them are generalizable to resource-limited settings. In a research study context, a possible solution to ease operational challenges may be to focus phone-based unannounced pill count efforts on a randomly selected sample from participants who are

Why use of dienogest for the first contraceptive pill with estradiol?

Science.gov (United States)

Mueck, Alfred O; Seeger, Harald; Bühling, Kai J

2010-02-01

Dienogest (DNG) has the essential properties of an effective progestogen for use in a new contraceptive pill using estradiol valerate as estrogenic component -- it inhibits ovulation and protects against endometrial proliferation. DNG is a derivative of norethisterone (NET), but has a cyanomethyl- instead of an ethinyl-group in C17 position which may offer a variety of benefits regarding hepatic effects. The similarity to NET is reflected in the high endometriotropy and in similar pharmacokinetics like short plasma half-live and high bioavailability. However, DNG also elicits properties of progesterone derivatives like neutrality in metabolic and cardiovascular system and considerable antiandrogenic activity, the latter increased by lack of binding to SHBG as specific property of DNG. It has no glucocorticoid and antimineralocorticoid activity and has no antiestrogenic activity with the consequence that possible beneficial estradiol effects should not be antagonized. This may be of special importance for the tolerability and safety of the first pill with estradiol valerate instead of ethinylestradiol, although well-designed postmarketing studies are still ongoing to demonstrate what can be expected on the basis of pharmacology.

To compare the effects of regular vs low-FODMAP rye bread on irritable bowel syndrome (IBS) symptoms and to study gastrointestinal conditions with SmartPill ® . Our aim was to evaluate if rye bread low in FODMAPs would cause reduced hydrogen excretion, lower intraluminal pressure, higher colonic pH, different transit times, and fewer IBS symptoms than regular rye bread. The study was a randomized, double-blind, controlled cross-over meal study. Female IBS patients ( n = 7) ate study breads at three consecutive meals during one day. The diet was similar for both study periods except for the FODMAP content of the bread consumed during the study day. Intraluminal pH, transit time, and pressure were measured by SmartPill, an indigestible motility capsule. Hydrogen excretion (a marker of colonic fermentation) expressed as area under the curve (AUC) (0-630 min) was [median (range)] 6300 (1785-10800) ppm∙min for low-FODMAP rye bread and 10 635 (4215-13080) ppm∙min for regular bread ( P = 0.028). Mean scores of gastrointestinal symptoms showed no statistically significant differences but suggested less flatulence after low-FODMAP bread consumption ( P = 0.063). Intraluminal pressure correlated significantly with total symptom score after regular rye bread (ρ = 0.786, P = 0.036) and nearly significantly after low-FODMAP bread consumption (ρ = 0.75, P = 0.052). We found no differences in pH, pressure, or transit times between the breads. Gastric residence of SmartPill was slower than expected. SmartPill left the stomach in less than 5 h only during one measurement (out of 14 measurements in total) and therefore did not follow on par with the rye bread bolus. Low-FODMAP rye bread reduced colonic fermentation vs regular rye bread. No difference was found in median values of intraluminal conditions of the gastrointestinal tract.

To explore the effects of qishenyiqi gutta pills on myocardial hypertrophy of left ventricle and calcium/calmodulin dependent protein kinase II (CAMK II) in rats with renal hypertension and elucidate its intervention mechanism for myocardial hypertrophy. A total of 50 Wistar rats were randomly divided into 5 groups of sham-operation, control, high-dose qishenyiqi gutta pills, low-dose qishenyiqi gutta pills and valsartan (n = 10 each). The rat model of myocardial hypertrophy with renal hypertension was established by the 2-kidney 1-clip (2K1C) method. The experimental animals were divided into control, high-dose, low-dose and valsartan groups. At Week 5 postoperation, valsartan group received an oral dose of valsartan (30 mg×kg(-1)×d(-1)), high-dose and low-dose groups took qishenyiqi gutta pills (250 and 125 mg×kg(-1)×d(-1)) while sham-operation and control groups had the same dose of normal saline solution. Tail arterial pressure was detected weekly and continued for 8 weeks. At the end of Week 12, the animals were sacrificed to harvest myocardial tissue of left ventricle for detecting left ventricular mass index (LVMI). The collagen volume fraction (CVF) of myocardium was examined by Van Gieson staining, the activities of superoxide dismutase (SOD) and reactive oxygen species (ROS) were detected by enzyme-linked immunosorbent assay (ELISA) and the expression of CAMK II was detected by immunohistochemistry and Western blot. (1) Blood pressures were significantly higher in high-dose, low-dose and control groups than those in sham-operation and valsartan groups ((167.66 ± 11.48), (166.72 ± 13.51), (174.34 ± 14.52) vs (119.57 ± 6.30), (131.80 ± 12.49) mm Hg, P pills may retard myocardial hypertrophy of left ventricle in rats with renal hypertension. And the mechanism is probably be correlated with its antioxidant activity and inhibited expression of myocardial CAMK II.

OBJECTIVES: Progestogen-only pills (POPs) are safer with respect to cardiovascular risks than contraceptives containing estrogens. Despite the increased contraceptive efficacy of a desogestrel-only pill compared with a traditional POP, POPs are still not widely used due to an unpredictable bleeding...... pattern. A new POP containing 4 mg drospirenone has been developed with a 24/4 intake regimen which may improve the bleeding pattern. The objectives of this study were to investigate ovulation inhibition with the new drospirenone-only pill in comparison with the desogestrel-only pill and, in addition......, to assess the effects on cervical mucus permeability and bleeding. METHODS: Sixty-four healthy volunteers with proven ovulatory cycles were randomised and treated with either the drospirenone-only or the desogestrel-only pill during two 28-day cycles. Follicular diameter, endometrial thickness, and serum...

In this study, a fast and effective high-performance liquid chromatography method was developed to obtain a fingerprint chromatogram and quantitative analysis simultaneously of four indexes including gallic acid, chlorogenic acid, albiflorin and paeoniflorin of the traditional Chinese medicine Moluodan Concentrated Pill. The method was performed by using a Waters X-bridge C 18 reversed phase column on an Agilent 1200S high-performance liquid chromatography system coupled with diode array detection. The mobile phase of the high-performance liquid chromatography method was composed of 20 mmol/L phosphate solution and acetonitrile with a 1 mL/min eluent velocity, under a detection temperature of 30°C and a UV detection wavelength of 254 nm. After the methodology validation, 16 batches of Moluodan Concentrated Pill were analyzed by this high-performance liquid chromatography method and both qualitative and quantitative evaluation results were achieved by similarity analysis, principal component analysis and hierarchical cluster analysis. The results of these three chemometrics were in good agreement and all indicated that batch 10 and batch 16 showed significant differences with the other 14 batches. This suggested that the developed high-performance liquid chromatography method could be applied in the quality evaluation of Moluodan Concentrated Pill. © 2016 WILEY-VCH Verlag GmbH & Co.

To investigate the effect of Biejiajian Pills on Wnt signal pathway and its inhibitory gene (DKK-1 and FrpHe) expressions and explore the mechanism underlying the action of Biejiajian Pills to suppress the invasiveness of hepatocellular carcinoma. Twenty-four Wistar rats were randomized equally into 3 groups for gavage of normal saline and Biejiajian Pills at 20- and 10-fold clinical doses for 3 days. Blood samples were then collected from the rats, and the serum was separated and added in HepG2 cell cultures. After 48 h of culture, the cells were collected to determine the cellular content of β-catenin protein using flow cytometry and detect DKK-1 and FrpHe mRNA expressions using qRT-PCR. HepG2 cells cultured in the presence of sera from rats fed with Biejiajian Pills showed significantly lowered β-catenin protein expression and obvious down-regulation of DKK-1 mRNA expression, and the effect was correlated with the doses of the drug administered. The expression of FrpHe mRNA showed no significant differences between the 3 groups. Biejiajian Pills can effectively inhibit the invasiveness and migration of hepatocellular carcinoma cells, which is closely related to decreased expressions of β-catenin and DKK-1 to cause block of the Wnt/β-catenin signal pathway.

An adiabatic demagnetization refrigerator (ADR) utilizes the magnetocholoric effect in a paramagnetic salt to produce sub-Kelvin temperatures. It is a solid-state device that has no moving parts and does not rely upon a density gradient in a working fluid. This makes it ideal for cooling space-based instruments. ·Typically the salt is enclosed in a cylindrical pill that is suspended within the bore of a magnet. The suspension between the salt pill and magnet must be robust enough to survive a launch yet have a thermal conductance that minimizes heat from the magnet that is mechanically, and thermally, anchored to a stage at a higher temperature. Here we detail such a design that uses Kevlar(Trade Mark) as the supporting media in a system that limits motion of the salt pill axial as well as laterally with respect to the magnet bore.

Oral contraceptive pills are among the most popular contraceptive methods, but the fear of cancer and cardiovascular disease overshadows its continuous use among women. This study aimed to define the association between consumption patterns of combined oral contraceptives among women with breast cancer. This is an analytical case-control study conducted on 175 women with breast cancer, referring to Seyed al Shohada Medical Center and private clinics in Isfahan to be treated and followed up in 2011, as well as 350 healthy women who were identical with the subjects in the study group regarding age and residential location. The data were collected using a researcher-made questionnaire. Content validity and Cronbach's alpha were employed to confirm validity and scientific reliability of the questionnaire, respectively. The data were analyzed by descriptive and analytical statistical methods through SPSS. The findings showed that there was a significant association between history of contraceptive pills' consumption and incidence of breast cancer (P pills' consumption compared to those with no history of that. It was also shown that pills' consumption for 36-72 months increased the risk of breast cancer by 2.18-fold, the age of the first use being less than 20 years increased the risk by 3.28-fold, and time since the last use of less than 25 years increased the risk by 2.63-fold. There was no significant association between duration of use, age of the first and last use, and time since the first and last use in the study and control groups. The results showed that history of pills' consumption is associated with incidence of breast cancer regardless of the consumption pattern. Use of oral contraceptives pills at any age and for any duration can increase the risk of breast cancer.

To observe the clinical effectiveness of Qilin Pills combined with sertraline in the treatment of secondary non-consolidated kidney qi premature ejaculation (PE). A total of 120 patients with secondary non-consolidated kidney qi PE were randomly assigned to groups A (aged [35.5 ± 5.4] yr), B (aged [36.2 ± 5.7] yr), and C (aged [35.2 ± 5.3] yr) in the ratio of 1:1:1 to receive Qilin Pills (once 6 g, bid), sertraline (once 50 mg, qd), and Qilin Pills plus sertraline, respectively, all for 4 weeks. The intravaginal ejaculatory latency time (IELT) and PE diagnostic tool (PEDT) scores were obtained before and after medication and at 1 month after drug withdrawal, and comparative analyses were made among the three groups of patients. The IELT was dramatically prolonged in groups A, B, and C after treatment ([3.23 ± 1.84], [3.87 ± 2.43], and [5.92 ± 3.11] min) and at 1 month after drug withdrawal ([1.85 ± 1.27], [1.52 ± 1.06], and [ 4.26 ± 1.88 ] min) as compared with the baseline ([0.88 ± 0.45], [0.84 ± 0.47], and [0.85 ± 0.50] min) (P Pills combined with sertraline has a definite efficacy in the treatment of secondary non-consolidated kidney qi PE and therefore deserves wide clinical application.

Investigating the structure and dynamics of the PIK3CA wild-type and H1047R oncogenic mutant.

Directory of Open Access Journals (Sweden)

Paraskevi Gkeka

2014-10-01

Full Text Available The PIK3CA gene is one of the most frequently mutated oncogenes in human cancers. It encodes p110α, the catalytic subunit of phosphatidylinositol 3-kinase alpha (PI3Kα, which activates signaling cascades leading to cell proliferation, survival, and cell growth. The most frequent mutation in PIK3CA is H1047R, which results in enzymatic overactivation. Understanding how the H1047R mutation causes the enhanced activity of the protein in atomic detail is central to developing mutant-specific therapeutics for cancer. To this end, Surface Plasmon Resonance (SPR experiments and Molecular Dynamics (MD simulations were carried out for both wild-type (WT and H1047R mutant proteins. An expanded positive charge distribution on the membrane binding regions of the mutant with respect to the WT protein is observed through MD simulations, which justifies the increased ability of the mutated protein variant to bind to membranes rich in anionic lipids in our SPR experiments. Our results further support an auto-inhibitory role of the C-terminal tail in the WT protein, which is abolished in the mutant protein due to loss of crucial intermolecular interactions. Moreover, Functional Mode Analysis reveals that the H1047R mutation alters the twisting motion of the N-lobe of the kinase domain with respect to the C-lobe and shifts the position of the conserved P-loop residues in the vicinity of the active site. These findings demonstrate the dynamical and structural differences of the two proteins in atomic detail and propose a mechanism of overactivation for the mutant protein. The results may be further utilized for the design of mutant-specific PI3Kα inhibitors that exploit the altered mutant conformation.

In the circumstances of direct market competition and the need to have a dominant market position, companies are necessarily forced to constantly upgrade and advance their offensive and defensive methods, techniques and strategies. In order to prevent a hostile takeover, the target company may resort to an array of defence mechanisms, the most prominent of which are 'poison pills'. In spite of being perceived as the most powerful tool for obstructing hostile takeovers (and commonly designated as the 'Holy Grail' among the defensive mechanisms, there are many pros and cons underlying their application. One of the positive effects of using the poison pills is that the fear of takeovers makes the target company management more disciplined and efficient in business operations. The negative consequences are reflected in the relationship between the company board of directors and the shareholders. The target company management makes a unilateral decision on using a poison pill and this decision does not have to be approved by the shareholders in the General Meeting; however, this is highly inconsistent with the basic principles of corporate governance. The asymmetry of information, where the management (an agent has disproportionately more relevant information at its disposal than the shareholders (principals, generates a conflict between the management and the shareholders. In company law, this agency problem is generally known as the principal-agent problem, which is most prominent in a takeover. Poison pills are often associated with the discrimination of the target company shareholders, but not necessarily. The controversial nature of this defensive measure which can be applied by the target company has given rise to numerous debates on the need to

Only one of three clinics initiated and maintained guidelines for extended COC use. In that service, 60% of staff prescribing COC advised more than 50% of patients regarding alternative COC regimens. In the other two services, this was discussed with 20% and 6% of patients, respectively (P < 0.001. The reasons for prescribing extended use included cyclic headaches, menorrhagia, patient request, menstrual-related cramps, and endometriosis, and did not differ between the three different settings. The most common extended regimens were 63 pills or continuous use until bleeding occurs, followed by a hormone-free interval. Concerns highlighted by providers and patients were “unhealthy not to have a monthly bleed”, “future fertility”, and “breakthrough bleeding”. Such comments highlight the need for further information for providers and patients.Conclusion: There is growing evidence, backed by national guidance, about extended COC use, but routine provision of this information is patchy and varies ten-fold, even within specialist family planning services. Targeted training, use of service guidelines, and implementation research will be

[Estrogens and feminine brain maturation during adolescence: emergency contraceptive pill].

López Moratalla, Natalia; Errasti Alcalá, Tania; Santiago, Esteban

2011-01-01

In the period between puberty and maturity takes place the process of brain maturation. Hormone levels induce changes in neurons and direct the architecture and structural functionality thus affecting patterns of development of different brain areas. The onset of puberty brings with it the invasion of the female brain by high levels of hormones, cyclic surges of estrogen and progesterone in addition to steroids produced in situ. Control centers of emotions (amygdala), memory and learning (hippocampus) and sexual activity (hypothalamus) are modified according to the cyclical concentrations of both hormones. Sex hormones stimulate multimodal actions, both short and longer terms, because neurons in various brain areas have different types of receptors, membrane, cytoplasmic and nuclear. The composition of emergency contraceptive pill (postcoital pill) with high hormonal content raises the urgency of a thorough knowledge about the possible effect that the lack of control of the menstrual cycle in a time of consolidation of brain maturation, can bring in structuring and development of brain circuitry. Changes in the availability of sex steroids during puberty and adolescence underlie psychiatric disorders whose prevalence is typically feminine, such as depression, anxiety disorders. It is a fundamental ethical duty to present scientific data about the influence of estrogen in young female brain maturation, both for full information to potential users, and also to induce the appropriate public health measures.

Capsule endoscopy, using the PillCam ESO and sending images at a rate of 4 frames per second (fps), has a high sensitivity and specificity in diagnosing gastroesophageal reflux disease (GERD) lesions. We tested a new device which produces images at a rate of 14 fps. The diagnostic performance and esophageal visualization of these two devices were compared. 42 patients with GERD symptoms and eight patients with a history of Barrett's esophagus had an esophagogastroduodenoscopy (EGD). All patients underwent capsule endoscopy of the esophagus within 1 hour prior to EGD. The first 25 patients had a capsule endoscopy examination with the 4-fps device. The following 25 patients underwent capsule endoscopy under identical conditions but using the 14-fps device. The reader of the capsule endoscopy study was blinded to the EGD findings. A diagnosis of GERD or Barrett's esophagus was established with EGD. The findings at capsule endoscopy were compared with the EGD findings. We also examined how frequently the esophagus in its entirety was visualized by these two devices. The 4-fps device diagnosed 16/19 cases of esophageal erosions or ulcers (sensitivity 84 %) and 6/8 cases of Barrett's esophagus (sensitivity 75 %). The 14-fps capsule diagnosed 16/16 cases of esophageal ulcers or erosions and 7/7 cases of Barrett's esophagus (sensitivity 100 %). The total diagnostic miss rate in the 4-fps group was 5/27 (18 %) whereas the diagnostic miss rate in the 14-fps group was 0/23 (0 %) P fps group and in 20/25 patients (80 %) in the 14-fps group ( P fps device and in 19/25 (76 %) by the 14-fps device ( P fps PillCam ESO capsule is consistent with the data obtained from fluoroscopic studies of swallowed PillCam capsules, showing that capsule speed may reach 20 cm/s. For the 14-fps PillCam this means one image transmitted per 3-cm segment at maximal capsule speed, therefore still allowing for full visualization of the entire esophagus.

How can a state control swallowing? The home use of abortion pills in Ireland.

Science.gov (United States)

Sheldon, Sally

2016-11-01

Evidence suggests that there is widespread home use of abortion pills in Ireland and that ending a pregnancy in this way is potentially safer than the alternatives available to many women. This paper argues that there is a strong case for women with unwanted pregnancies to be offered truthful and objective information regarding the use of abortion pills by trusted local professionals and, further, that this is possible within existing law. A move in this direction would not, however, negate the need for legal reform to address the fundamental moral incoherence of a law that treats women who terminate pregnancies within Ireland as criminals but those who travel to access services overseas as victims in need of support. In support of these arguments, the paper draws on both library research and a small number of interviews with government officials, service providers and activists. Copyright © 2016 Elsevier Inc.

To study the complications and consequences including maternal morbidity and mortality following indiscriminate self-consumption of abortion pills reporting to a tertiary care center. This is an observational study conducted at Vanivilas hospital between January 2012 to December 2013 for 24 months. After applying inclusion and exclusion criteria, 104 women were studied with respect to period of gestation, parity, clinical features at presentation and management in the institution. An analysis of maternal morbidity and mortality was done with respect to surgical interventions, ICU admissions, need for blood transfusions and maternal deaths. In this study, there were 75 (72.2 %) cases of incomplete abortion, 10 (9.6 %) cases of missed abortion, 2 (1.9 %) cases of ruptured ectopic and 2 (1.9 %) cases of rupture uterus. Seventy-eight (75 %) cases received blood transfusion, 7 (6.7 %) were admitted to ICU, and 2 (1.9 %) developed acute kidney injury. There were 2 (1.9 %) maternal deaths in the study group. This study shows urgent need for legislation and restriction of drugs used for medical termination of pregnancy. Drugs should be made available via health care facilities under supervision to reduce maternal mortality and morbidity due to indiscriminate use of these pills.

To investigate the effect of Biejiajian Pills on the expressions of the signal molecules and target genes of Wnt signal pathway in HepG2 cells and explore the mechanisms by which Biejiajian pills suppress the invasiveness of hepatocellular carcinoma. HepG2 cells were cultured for 48 h in the presence of serum collected from rats fed with Biejiajian Pills. The expressions of β-catenin, GSK-3β and P-GSK-3β in the cultured cells were assessed by Western blotting and the expressions of CD44v6 and VEGF were detected using immunohistochemistry. HepG2 cells cultured with the serum of rats fed with Biejiajian Pills showed lowered expressions of β-catenin protein both in the cytoplasm and the nuclei with also inhibition of phosphorylation of GSK-3β and reduced expression of CD44v6 and VEGF. Biejiajian Pills can significantly reduce the expression of β-catenin by decreasing the phosphorylation of GSK-3β and blocking the Wnt/β-catenin signaling pathway to cause down-regulation of the target genes CD44v6 and VEGF, which may be one of the molecular mechanisms by which Biejiajian Pills suppress the proliferation and invasiveness of hepatocellular carcinoma.

Antitumor Efficacy of the Dual PI3K/mTOR Inhibitor PF-04691502 in a Human Xenograft Tumor Model Derived from Colorectal Cancer Stem Cells Harboring a PIK3CA Mutation.

Directory of Open Access Journals (Sweden)

Douglas D Fang

Full Text Available PIK3CA (phosphoinositide-3-kinase, catalytic, alpha polypeptide mutations can help predict the antitumor activity of phosphatidylinositol-3-kinase (PI3K/mammalian target of rapamycin (mTOR pathway inhibitors in both preclinical and clinical settings. In light of the recent discovery of tumor-initiating cancer stem cells (CSCs in various tumor types, we developed an in vitro CSC model from xenograft tumors established in mice from a colorectal cancer patient tumor in which the CD133+/EpCAM+ population represented tumor-initiating cells. CD133+/EpCAM+ CSCs were enriched under stem cell culture conditions and formed 3-dimensional tumor spheroids. Tumor spheroid cells exhibited CSC properties, including the capability for differentiation and self-renewal, higher tumorigenic potential and chemo-resistance. Genetic analysis using an OncoCarta™ panel revealed a PIK3CA (H1047R mutation in these cells. Using a dual PI3K/mTOR inhibitor, PF-04691502, we then showed that blockage of the PI3K/mTOR pathway inhibited the in vitro proliferation of CSCs and in vivo xenograft tumor growth with manageable toxicity. Tumor growth inhibition in mice was accompanied by a significant reduction of phosphorylated Akt (pAKT (S473, a well-established surrogate biomarker of PI3K/mTOR signaling pathway inhibition. Collectively, our data suggest that PF-04691502 exhibits potent anticancer activity in colorectal cancer by targeting both PIK3CA (H1047R mutant CSCs and their derivatives. These results may assist in the clinical development of PF-04691502 for the treatment of a subpopulation of colorectal cancer patients with poor outcomes.

Despite the commitment of the Democratic Republic of the Congo (DRC) to expand the family planning method mix and increase access to services, awareness of emergency contraception is low among women, and the method remains underused and poorly integrated in family planning programming. Data from 15 focus group discussions conducted in 2016 among women aged 15-35 were used to examine awareness and perceptions of, and attitudes toward, emergency contraceptives. After facilitators explained emergency contraceptive pills' mechanism of action and other characteristics, participants were asked about the potential benefits and risks of making the method more widely available. Transcripts were analyzed using an iterative approach. Women reported employing a wide range of postcoital contraceptive behaviors, albeit often using inappropriate products, and generally agreed that emergency contraceptive pills seemed to be a potentially effective solution to their family planning needs. Perceived benefits and limitations of the method were almost always framed in reference to other, better-known contraceptives, and women expressed strong preferences for pharmacy-based provision that aligned with their usual behaviors for obtaining contraceptives. Participants were reluctant to see the method available for free. Emergency contraceptive pills have the potential to address gaps in the family planning method mix in the DRC. Assessing whether women have incomplete or erroneous information about family planning methods can provide better understanding of women's contraceptive choices in low-income countries.

Acceptability of the use of cellular telephone and computer pictures/video for "pill counts" in buprenorphine maintenance treatment.

Welsh, Christopher

2016-01-01

As part of a comprehensive plan to attempt to minimize the diversion of prescribed controlled substances, many professional organization and licensing boards are recommending the use of "pill counts." This study sought to evaluate acceptability of the use of cellular phone and computer pictures/video for "pill counts" by patients in buprenorphine maintenance treatment. Patients prescribed buprenorphine/naloxone were asked a series of questions related to the type(s) of electronic communication to which they had access as well as their willingness to use these for the purpose of performing a "pill/film count." Of the 80 patients, 4 (5 percent) did not have a phone at all. Only 28 (35 percent) had a "smart phone" with some sort of data plan and Internet access. Forty (50 percent) of the patients had a phone with no camera and 10 (12.5 percent) had a phone with a camera but no video capability. All patients said that they would be willing to periodically use the video or camera on their phone or computer to have buprenorphine/naloxone pills or film counted as long as the communication was protected from electronic tampering. With the advent of applications for smart phones that allow for Health Insurance Portability and Accountability Act of 1996-compliant picture/video communication, a number of things can now be done that can enhance patient care as well as reduce the chances of misuse/diversion of prescribed medications. This could be used in settings where a larger proportion of controlled substances are prescribed including medication assisted therapy for opioid use disorders and pain management programs.

In this study, the rat type 2 diabetes mellitus (T2DM) model was established through tail vein injection with low dose of streptozotocin (STZ) and high fat diet for 8 weeks, and then treated with Jiaotai Pill. The oral glucose tolerance test (OGTT), fasting serum insulin (FINS), free fatty acid(FFA) levels and blood lipid were assayed. HOMA-IR was calculated. Pancreatic pathology was performed. And pancreatic triglyceride (TG) content was examined by the lipid extraction method. Pancreatic islet cell apoptosis were detected by terminal dexynucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL). According to the results, the model group showed abnormal OGTT, increased FINS, HOMA-IR, FFA, lipid disorder, obvious fat accumulation and significantly increased TG content in pancreatic tissues, and enhanced pancreatic islet cell apoptosis. Compared with the model group, the Jiaotai Pill group displayed improved OGTT, reduced FINS, HOMA-IR, FFA, recovered lipid disorder, decreased fat accumulation and significantly declined TG content in pancreatic tissues, and lowered pancreatic islet cell apoptosis. In summary, Jiaotai pill could effectively treat type 2 diabetes in rats. Its mechanism may be related to the reduction in pancreatic fat accumulation and islet cell apoptosis.

Using Caffeine Pills for Performance Enhancement. An Experimental Study on University Students’ Willingness and Their Intention to Try Neuroenhancements

2016-01-01

Recent research has indicated that university students sometimes use caffeine pills for neuroenhancement (NE; non-medical use of psychoactive substances or technology to produce a subjective enhancement in psychological functioning and experience), especially during exam preparation. In our factorial survey experiment, we manipulated the evidence participants were given about the prevalence of NE amongst peers and measured the resulting effects on the psychological predictors included in the Prototype-Willingness Model of risk behavior. Two hundred and thirty-one university students were randomized to a high prevalence condition (read faked research results overstating usage of caffeine pills amongst peers by a factor of 5; 50%), low prevalence condition (half the estimated prevalence; 5%) or control condition (no information about peer prevalence). Structural equation modeling confirmed that our participants’ willingness and intention to use caffeine pills in the next exam period could be explained by their past use of neuroenhancers, attitude to NE and subjective norm about use of caffeine pills whilst image of the typical user was a much less important factor. Provision of inaccurate information about prevalence reduced the predictive power of attitude with respect to willingness by 40-45%. This may be because receiving information about peer prevalence which does not fit with their perception of the social norm causes people to question their attitude. Prevalence information might exert a deterrent effect on NE via the attitude-willingness association. We argue that research into NE and deterrence of associated risk behaviors should be informed by psychological theory. PMID:26903909

Zuojin Pill has been shown to inhibit the cytochrome P450 (CYP) 2D6 isoenzyme in vitro. In Chinese individuals, CYP 2D6*10 is the most common allele with reduced enzyme activity. In this study, we investigated the pharmacokinetic interaction between Zuojin Pill and the sensitive CYP2D6 probe dextromethorphan in healthy Chinese volunteers with CYP2D6*10 genotype. A pharmacokinetics interaction study was carried out in three groups with CYP2D6*1/*1 (n = 6), CYP2D6*1/*10 (n = 6), and CYP2D6*10/*10 (n = 6) genotypes. Each participant received a single oral dose of dextromethorphan (15 mg) followed by Zuojin Pill (3 g twice daily) for 7 days, and received 3 g Zuojin Pill with 15 mg dextromethorphan in the last day. Blood samples (0-24 h) and urine samples (0-12 h) were collected at baseline and after the administration of Zuojin Pill, and the samples' concentration of dextromethorphan and its main metabolite dextrorphan was determined. Compared to baseline values, co-administration of Zuojin Pill (3 g twice daily) for 7 days increased the AUC0-24 of dextromethorphan [mean (90 % CI)] by 3.00-fold (2.49∼3.61) and 1.71-fold (1.42∼2.06), and decreased oral clearance(CL/F) by 0.27-fold (0.2-0.40) and 0.57-fold (0.48-0.67) in the participants with CYP2D6*1/*1 and CYP2D6*1/*10 genotypes, respectively. In contrast, no significant change was observed in these pharmacokinetic parameters of the participants with CYP2D6*10/*10 genotype. These data demonstrated that administration of Zuojin Pill inhibited moderately CYP2D6-mediated metabolism of dextromethorphan in healthy volunteers. The inhibitory influence of CYP2D6 was greater in CYP2D6*1/*1 and CYP2D6*1/*10 groups than CYP2D6 *10/*10 group.

Giant pill-millipedes (order Sphaerotheriida) are large-bodied millipedes without poison glands which can roll-up into a complete ball. Their disconnected area of distribution spanning South Africa, Madagascar, India, SE Asia, Australia and New Zealand makes them interesting model organisms for biogeographic studies. The here presented phylogeny is based on a molecular dataset covering all areas of distribution with a special focus on Madagascar, where some species of giant pill-millipedes show island gigantism, reaching the size of a baseball. For our study, two mitochondrial genes (partial 16S rRNA and COI) as well as the complete nuclear 18S rDNA were sequenced. While many recent vertebrate studies hint that the ancestors of the recent Malagasy fauna crossed the >350 km wide Mozambique Channel several times, no such crossing was discovered in the Sphaerotheriida. For the first time in a molecular phylogenetic study of soil arthropods, a Madagascar-India group, the family Arthrosphaeridae, is recovered, hinting to a Gondwanan origin of the Sphaerotheriida. The Malagasy-Indian family Arthrosphaeridae forms a monophyletic, statistically well-supported group in all obtained trees. The giant pill-millipedes from Madagascar are paraphyletic because the Malagasy genus Sphaeromimus is the sister-taxon of the Indian Arthrosphaera. In Sphaeromimus, an ecotone shift occurred only once: the spiny forest species Sphaeromimus musicus forms the sister-clade to the species collected in rainforests and littoral rainforests. The two species of the Malagasy genus Zoosphaerium which express island gigantism form a monophyletic group in some trees, but these trees lack good statistical support. Deeper nodes inside the Sphaerotheriida, like the position of the Australian genera Procyliosoma and Epicyliosoma, the Southeast Asian family Zephroniidae and the South African genus Sphaerotherium could not be resolved. This study is the first genetic study inside the order Sphaerotheriida

To study the effect of Biejiajian Pills on Wnt signal pathway and the mechanisms underlying its action to suppress the invasiveness of hepatocellular carcinoma. HepG2 cells cultured in the serum of rats fed with Biejiajian Pills for 48 h were examined for β-catenin expression using immunofluorescence, β-catenin/TCF4 complex activity with luciferase, and expressions of the downstream proteins cyclin D1 and MMP-2 using qRT-PCR. Biejiajian Pills-treated sera significantly reduced the expressions of cytoplasmic and nuclear β-catenin protein, cyclin D1 and MMP-2 proteins and lowered the activities of β-catenin/TCF4 complex. Biejiajian Pills may serve as a potential anti-tumor agent, whose effect might be mediated by inhibiting the Wnt/β-catenin pathway.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by swelling and painful joints, eventually leading to joint destruction. There is still a lack of effective therapy to treat RA. The Juanbi pill is a Chinese medicine that has been widely used to treat active RA in China for hundreds of years, relieving pain and protecting the affected joints from malformation. However, there is no solid evidence to show the effect of the Juanbi pill on the management of active RA. We will conduct a multicenter, randomized, double-blind, placebo-controlled clinical trial to determine whether the traditional Chinese medicine Juanbi pill could relieve joint pain in RA and protect the joints. A total of 120 patients with active RA will be enrolled and treated with the Juanbi pill or a placebo for 3 months. The primary outcome measures are as follows: rate of in the American College of Rheumatology (ACR)50, change in the 28-joint Disease Activity Score (DAS28) from baseline at beginning of therapy to 3 months, and a change in the van der Heijde modified Sharp score measured from baseline to 12 months. The secondary outcome measures are as follows: rate of change in ACR20, ACR70, Health Assessment Questionnaire-Disability Index (HAQ-DI), and change in score in the Patient Assessment of Arthritis Pain, Patient Global Assessment of Arthritis, and the Athens Insomnia Scale (AIS) from baseline to 2-week, 1-month, 2-month, 3-month, 6-month, and 12-month follow up. In addition, the rate of change (score) in the ACR50 and DAS28 from the baseline to 2-week, 1-month, 2-month, 6-month, and 12-month follow up are also the secondary outcome measures. Although the Juanbi pill has been used in China for many years to treat RA, there is a lack of consensus about its effectiveness. This trial will provide convincing evidence about the effect of Juanbi pill on active RA. ClinicalTrials.gov, NCT02885597 . Registered on 30 August 2016.

"They're legal so they're safe, right?" What did the legal status of BZP-party pills mean to young people in New Zealand?

Science.gov (United States)

Sheridan, Janie; Butler, Rachael

2010-01-01

The legislation on psychoactive substances has a role to play with regard to shaping social values and influencing the normalisation of drug use. In New Zealand from 2005 to 2008, benzylpiperazine-containing 'legal' party pills (BZP-party pills) were legally available for purchase, subject to controls around a minimum purchase age of 18 years, and prohibitions on free of charge distribution and advertising in certain media. This paper explores what their legal status communicated to young users. Interviews and group discussions with young people (n=58) who had used BZP-party pills in the preceding 6 months. Data were collected between June and December 2006 via a series of interviews with individuals, 'friendship' pairs, and groups comprised of participants known to each other. Young people saw BZP-party pills as 'safe' and of good quality as they were legal/government sanctioned, but also thus of inferior strength, suggesting they could take more of them. However, after using them they often reviewed their view of their safety and quality due to varied experiences. Being legal for some people meant they could use the substances without breaking the law, or having to go to 'dealers'. Their legal status also meant they were easily accessible and were seen to be 'socially acceptable', with some young people indicating they would be happy to discuss their use with their parents. However, social acceptability was, for some, a reason not to use them. These data provide a unique insight into the tension between positive and negative harm reduction messages relating to the legal nature of psychoactive drugs and as such begin to fill an information void in this area. The legal status of these 'party pills' conveys mixed messages to young people and whilst being seen as potentially safe and of good quality, this often leads to higher than 'recommended' doses being used. Nevertheless, not breaking the law or having to access BZP-party pills from 'dealers', and being able to

Full Text Available Placebo treatments and healing rituals have been used to treat pain throughout history. The present within-subject crossover study examines the variability in individual responses to placebo treatment with verbal suggestion and visual cue conditioning by investigating whether responses to different types of placebo treatment, as well as conditioning responses, correlate with one another. Secondarily, this study also examines whether responses to sham acupuncture correlate with responses to genuine acupuncture. Healthy subjects were recruited to participate in two sequential experiments. Experiment one is a five-session crossover study. In each session, subjects received one of four treatments: placebo pills (described as Tylenol, sham acupuncture, genuine acupuncture, or no treatment rest control condition. Before and after each treatment, paired with a verbal suggestion of positive effect, each subject's pain threshold, pain tolerance, and pain ratings to calibrated heat pain were measured. At least 14 days after completing experiment one, all subjects were invited to participate in experiment two, during which their analgesic responses to conditioned visual cues were tested. Forty-eight healthy subjects completed experiment one, and 45 completed experiment two. The results showed significantly different effects of genuine acupuncture, placebo pill and rest control on pain threshold. There was no significant association between placebo pills, sham acupuncture and cue conditioning effects, indicating that individuals may respond to unique healing rituals in different ways. This outcome suggests that placebo response may be a complex behavioral phenomenon that has properties that comprise a state, rather than a trait characteristic. This could explain the difficulty of detecting a signature for "placebo responders." However, a significant association was found between the genuine and sham acupuncture treatments, implying that the non

The current study aims to evaluate the effect of the use of single packet of levonorgestrel emergency contraceptive pills (LNG-ECPs) during breastfeeding on the health and development of the nursing infant. The current study was an ancillary observational cohort study carried out in a university hospital. We counseled all women delivered and planning birth-space and breastfeed for at least 1 year for participation during postpartum hospital stay. Eligible participants for inclusion in the randomized controlled trial (NCT 01111929) were allocated to receive adequate Lactational Amenorrhea Method (LAM) counseling (LAM-only group) or the LAM counseling in addition to counseling about LNG-ECPs use (LAM + emergency contraception (EC) group). These pills were to be used once if unprotected intercourse did occur after expiry of any of the LAM prerequisites and before the couples started to use a reliable method of contraception. We included the first 100 women in the LAM + EC who did use the pills and the first 100 women in the control group who completed the follow-up visits for 6 months to draw the infants' outcome. The primary outcome was the difference of anthropometric measurements of the infants at 3 and 6 months postpartum. Secondary outcome was the difference in the Psycho-social, fine and gross motor, and language development using Denver development screening test. There were no statistical significant differences between both the groups regarding the infants' weight, length, head circumference, chest circumference, and mid-arm circumference at each visit (p > .05). Additionally, there were no statistically significant differences regarding all items (psycho-social, fine and gross motor, and language) of Denver development screening test between the infants in LAM-only and LAM + EC groups (p = .081). The use of single packet of LNG-ECPs during breastfeeding not objectively affects health and development of nursing infants or subjectively

Nonevaporable getter (NEG) pumps are widely used for maintaining a clean ultrahigh vacuum (UHV) of ≤10"−"8" Pa because of their high pumping speeds for hydrogen (H_2) and active gases in the UHV region. In addition, they are oil free, evaporation free, sputtering free, sublimation free, magnetic field free, vibration free, economical, compact, lightweight, and energy saving. In the present paper, the authors report a new NEG pump which is composed of commercial 60 NEG pills (ϕ10 × 3 mm; 70 wt. % Zr, 24.6 wt. % V, and 5.4 wt. % Fe), titanium parts, a DN 40 conflat flange, and a tantalum heater. The NEG pills are vertically and radially aligned around the heater to maximize the effective area for pumping. After activation at 400 °C for 30 min, the pumping speeds of the NEG pump were measured with the orifice method. Pumping speeds of 140–130, 200–140, 190–130, and 35–17 l/s were estimated for H_2, CO, CO_2, and N_2 gasses, respectively, in a pumped-quantity range of 0.01–0.1 Pa l. Since the NEG pump is composed of a heating unit and a NEG module, the pumping speeds can be improved by increasing the number of NEG modules. These NEG pumps are favorable alternatives to sputtering ion pumps or titanium sublimation pumps.

Glaciers, especially in mountain area are sensitive indicators of climate fluctuations and also contribute to present rates of sea level rise. In Central Asia, these glaciers are the primary resource for fresh water. Understanding the seasonal behavior of these glaciers would help to make efficient use of the available water reservoir. Different methods have been employed to study glacier displacements in past. The conventional survey techniques are very cost-intensive and highly depend on accessibility to high mountain glaciers also directs us to look for new ways to study these areas. Here remote sensing comes in handy with freely available data and a good coverage with high spatial and temporal resolution. Optical satellite imagery, available free can be effectively used for research purpose. The glacier in this region fed lake Karakul (380 km2), the largest Lake in Tajikistan. The objective is to study the displacement tendency of the Glacier in Pik Lenin area using Landsat 7 dataset. Normalized cross correlation algorithm has been implemented via CIAS to estimate the motion of glacier surface. A number of combination of reference block and search area size were tested for 30 m resolution dataset. As a result the specifications: reference block size of 15 pixels and search area size of 10 pixels was found out as the best set of parameters and considered for further processing. The study derives a reliable set of data depicting the velocities in the glacier which after post processing shows peak velocity of 121 m/y of the glacier.

Traditional Chinese medicine consists of complex phytochemical constituents. Selecting appropriate analytical markers of traditional Chinese medicine is a critical step in quality control. Currently, the combination of fingerprinting and efficacy evaluation is considered as a useful method for screening active ingredients in complex mixtures. This study was designed to develop an orthogonal partial least squares model for screening bioactive quality control markers of QishenYiqi dripping pills based on the fingerprint-efficacy relationship. First, the chemical fingerprints of 49 batches of QishenYiqi dripping pill samples were established by ultra-high performance liquid chromatography coupled with a photodiode array detector. Second, ultra-high performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry was exploited to systematically investigate the 36 copossessing fingerprint components in QishenYiqi dripping pills. The vascular protective activity of QishenYiqi dripping pills was determined by using a cell counting kit-8 assay. Finally, fingerprint-efficacy relationship was established by orthogonal partial least squares model. The results indicated that ten components exhibited strong correlation with vascular protective activity, and these were preliminarily screened as quality control markers. The present study provided a novel idea for the study of the pharmacodynamic material basis and quality evaluation of QishenYiqi dripping pills. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Controversial opinions exist about the possible mechanisms throughout emergency contraception prevents pregnancy. Recently, the International Federation of Gynaecology and Obstetrics and the International Consortium for Emergency Contraception released a Joint Statement declaring that 'inhibition or delay of ovulation should be their primary and possibly only mechanism of action'. They still added that 'Review of the evidence suggests that LNG-ECPs cannot prevent implantation'. Concerning levonorgestrel-only emergency contraceptive pills effects on ovulation, the Statement based on seven reference papers which considered a total of only 142 patients, divided into still different subgroups. Basing on their same references we got quite different conclusions.

"Pregnancy and labour cause more deaths than oral contraceptives": The debate on the pill in the Spanish press in the 1960s and 1970s.

From 1941 to 1978, Franco's regime in Spain banned all contraceptive methods. The pill started circulating in Spain from the 1960s, officially as a drug used in gynaecological therapy. However, in the following decade it was also increasingly used and prescribed as a contraceptive. This paper analyses debates about the contraceptive pill in the Spanish daily newspaper ABC and in two magazines, Blanco y Negro and Triunfo, in the 1960s and 1970s. It concludes that the debate on this contraceptive method was much more heterogeneous than might be expected given the Catholic-conservative character of the dictatorship. The daily press focused on the adverse effects of the drug and magazines concentrated on the ethical and religious aspects of the pill and discussed it in a generally positive light. Male doctors and Catholic authors dominated the debate. © The Author(s) 2013.

Oligoasthenozoospermia is a crucial factor in male infertility. Wuzi Yanzong (WZYZ) pill is a popular traditional Chinese medicine (TCM) formula which has been used for male infertility treatment for years. However, its effects on semen quality remain controversial. We conducted a preregistered meta-analysis to assess the effect of WZYZ pill for the therapeutic effects on oligoasthenozoospermia. Five randomized controlled trials including 960 participants were selected from databases of domains in North-East Asian regions, PubMed, Embase, and Cochrane Library. WZYZ pill group yielded a greater mean increment on sperm concentration (5 trials: MD 5.99, 95% CI 2.12–9.85, P = 0.002), sperm motility (5 trials: MD 4.57, 95% CI 0.47–8.68, P = 0.03), sperm morphology (2 trials: MD −1.93, 95% CI −4.87–1.01, P = 0.20), activity of acrosomal enzyme (2 trials: MD 28.27, 95% CI 12.41–44.14, P < 0.01), volume of semen (2 trials: MD 0.56, 95% CI 0.21–0.91, P = 0.002), and a decrement of sperm DNA fragmentation index (2 trials: MD −3.82, 95% CI −6.45–−1.19, P = 0.004). However, qualities of selected studies were generally unsatisfactory, and there was inherent heterogeneity among some of the outcomes. Despite these limitations, the WZYZ pill improved sperm quality by improving several semen parameters and decreasing DNA damage in oligoasthenozoospermia patients. PMID:29576794

A fast micellar electrokinetic chromatography fingerprint method combined with quantification was developed and validated to evaluate the quality of Fufang Danshen Pills, a traditional Chinese Medicine, which has been used in the treatment of cardiovascular system diseases, in which the tetrahedron optimization method was first used to optimize the background electrolyte solution. Subsequently, the index of the fingerprint information amount of I was performed as an excellent objective indictor to investigate the experimental conditions. In addition, a systematical quantified fingerprint method was constructed for evaluating the quality consistency of 20 batches of test samples obtained from the same drug manufacturer. The fingerprint analysis combined with quantitative determination of two components showed that the quality consistency of the test samples was quite good within the same commercial brand. Furthermore, the partial least squares model analysis was used to explore the fingerprint-efficacy relationship between active components and antioxidant activity in vitro, which can be applied for the assessment of anti-oxidant activity of Fufang Danshen pills and provide valuable medicinal information for quality control. The result illustrated that the present study provided a reliable and reasonable method for monitoring the quality consistency of Fufang Danshen pills. © 2016 WILEY-VCH Verlag GmbH & Co.

Serum levels of thyroxine and triiodothyronine were determined in 24 workers engaged in contraceptive pills industry and 20 control subjects. Serum thyroxine in exposed subjects was significantly lower, compared to its level in controls. On the other hand, triiodothyronine was significantly higher in exposed workers. Thus, it is concluded that exposure to the dust of contraceptive drugs, namely estrogen and progesterone, produced disturbances in thyroid gland function and thyroid hormone metabolism. (author)

BACKGROUND Is the timing of dosing for amlodipine and atorvastatin important with regard to therapeutic efficacy? To answer this question, we designed an outpatient, practice-based, case-control study lasting 8 weeks. MATERIAL AND METHODS Two hundred patients were divided into 2 groups: in Group I, patients were provided with a single pill containing amlodipine/atorvastatin (5/20 mg) to be taken each night at 10 pm, and in Group II, patients were taking amlodipine (5 mg) and atorvastatin (20 mg) each morning at 7 am. RESULTS Our results indicated no obvious difference in blood pressure control between the 2 groups. Taking amlodipine at night not only lowered blood pressure, but it also provided better control during the peak blood pressure in the morning. Hypercholesterolemia control in the 2 groups was also not significantly different, taking atorvastatin in the morning was as effective as dosing at night in patients with hypercholesterolemia. While the carotid IMT, hs-CRP, and LVMI were significantly lower after treatment, no differences were found between the 2 groups. Although no obvious difference was found in adverse drug reactions between the 2 groups, compliance was much better in the single-pill group than in patients taking the 2 medications separately. CONCLUSIONS In conclusion, single-pill amlodipine-atorvastatin taken at night can lower blood pressure and reduce the morning peak blood pressure levels the next day. Additionally, this dosing method could improve patient adherence to the therapy.

This was an intervention study to compare the effects of health education alone and health education plus advance provision of emergency contraception (EC) pills on the knowledge and attitudes to EC by female students of University of Nigeria in South-East Nigeria. A structured questionnaire was used to collect data in February, 2009 from 290 female students of a tertiary educational institution (140 in the study group and 150 from the control group) who were selected by multistage sampling. Subsequently, health education was conducted among all the students. In addition, a pack containing 2 tablets of EC pills (Postinor) was given only to the students in the study group. Three months after this intervention, its effects were assessed through a survey using the same structured questionnaire employed in the baseline survey. knowledge of EC was significantly higher among the study group than the controls at post-intervention, P education plus advance provision of EC pills effectively improved knowledge and attitudes to EC among female students of tertiary institutions more than health education alone and this should be promoted.

Madagascar is one of the world's most important hotspots of biodiversity and a center for localized endemism. Among the highly endemic faunal elements are the giant pill-millipedes, order Sphaerotheriida, which are severely understudied in Madagascar. Here we provide descriptions of two new species of endemic giant-pill millipedes of the genus Zoosphaerium Pocock, 1895: Zoosphaerium bemanevika n. sp. and Zoosphaerium minutus n. sp.. Zoosphaerium bemanevika n. sp. belongs to the Z. coquerelianum species-group, while Z. minutus n. sp. is not assignable to a species-group. An updated key to the 19 species of the Z. coquerelianum group is provided. Zoosphaerium minutus n. sp. has a body length of Madagascar, an only recently protected area that represents a Malagasy center of endemism.

Full Text Available Introduction. Rheumatoid arthritis (RA is a polygenic disease associated with accelerated atherosclerosis and increased cardiovascular (CV mortality. Recent studies have identified the ABO rs579459, PPAP2B rs17114036, and ADAMTS7 rs3825807 polymorphisms as genetic variants associated with coronary artery disease and the PIK3CG rs17398575 and EDNRA rs1878406 polymorphisms as the most significant signals related to the presence of carotid plaque in nonrheumatic Caucasian individuals. Accordingly, we evaluated the potential relationship between these 5 polymorphisms and subclinical atherosclerosis (assessed by carotid intima-media thickness (cIMT and presence/absence of carotid plaques and CV disease in RA. Material and Methods. 2140 Spanish RA patients were genotyped for the 5 polymorphisms by TaqMan assays. Subclinical atherosclerosis was evaluated in 620 of these patients by carotid ultrasonography technology. Results. No statistically significant differences were found when each polymorphism was assessed according to cIMT values and presence/absence of carotid plaques in RA, after adjusting the results for potential confounders. Moreover, no significant differences were obtained when RA patients were stratified according to the presence/absence of CV disease after adjusting for potential confounders. Conclusion. Our results do not confirm association between ABO rs579459, PPAP2B rs17114036, ADAMTS7 rs3825807, PIK3CG rs17398575, and EDNRA rs1878406 and subclinical atherosclerosis and CV disease in RA.

Based upon flyers and advertisements for the contraceptive pill from 1961 until 2005, this paper discusses the ways in which the drug and its female users were represented in the marketing of two West European countries, France and the German Federal Republic. As my analysis suggests, national differences are only discernible in the marketing until the end of the 1970s. In West Germany, the pill was depicted from early on as a contraceptive, whereas, due to the restrictive legal situation, in France the pill was marketed as a multi-purpose drug. Nevertheless, the sources in both countries emphasized the safety of the drug. Likewise the representations of women changed from the notion of the married mother to a more diverse image, including young, modern and active women. From the early 1980s on, French and German materials conformed to one another. Now more classification systems were developed, emphasizing the differences between types of pills and types of women. Lifestyle, leisure and fun became increasingly central topics. Correspondingly, the female user was often portrayed in a sexualized way and represented as an active consumer with individual needs and wishes.

Ovarian epithelial cancers are among the most lethal women's cancers. There is no doubt about the preventive role of oral contraceptive pills (OCPs) in development of ovarian cancers. But, there are limited numbers of studies to address the effect of these agents on the number of cortical inclusion cysts (CICs), their epithelial type and suppression of the metaplastic phenomenon by these pills. The aim of this study was to clarify the role of these agents in the prevention of these cyst formation and tubal metaplasia and also examine the mesenchymal-epithelial transition theory in this context by immunohistochemical methods. The representative section(s) of ovarian cortex from a total number of 201 consecutive total abdominal hysterectomy with bilateral or unilateral salpingo-oophorectomy specimens were examined for mean number of CICs and their epithelial type between two groups of the patients. Group A included the patients who were on oral contraceptive pills for more than 5 years. All of the subjects with other contraceptive methods or a history of less than 5 years contraceptive pills usage were stratified in group B. Sections from 20 cases in which more than five inclusion cysts were found, were selected for IHC staining with calretinine and PAX8 as markers for mesothelium and mullerian epithelium respectively. The mean age of the patients was 51.67 years with no significant differences between two groups. The mean number of cysts were 1.27 and 3.23 in group A and B respectively (P =0.0001). Similarly the mean number of CICs, lined by tubal epithelium, was significantly different between two groups (0.65 vs 2.65, P =0.0001). In IHC staining 123 out of 150 CICs (82 %) were PAX+ while only 7 CICs (4.8 %) showed positive reaction for calretinin irrespective of type of epithelium. Our findings showed that the use of OCP for more than five years in women, significantly prevents development of cortical inclusion cysts in the ovaries which lined by tubal

Oral contraceptive pills are safe, effective, and available without a prescription in most countries. Despite support from the American Congress of Obstetricians and Gynecologists to provide oral contraceptives as an over-the-counter medication, US women are still required to have a prescription to obtain them. Use of online applications and the Internet has made most things easier to obtain in our society and this includes contraceptive methods. Several online ventures are now underway to enable US women to obtain oral contraceptives without visiting a medical provider's office. Women's health care professionals should encourage these novel approaches, as they will improve contraceptive access. As US women experiment with innovative health care models, providers will need to lead, follow, or be left behind. Copyright © 2015 Elsevier Inc. All rights reserved.

Full Text Available Fred Burbank Salt Creek International Women's Health Foundation, San Clemente, CA, USA Purpose: To determine whether sham pads used as controls in randomized clinical trials of vibratory stimulation to treat patients with sleep loss associated with restless legs syndrome perform differently than placebo pills used in comparable restless legs syndrome drug trials. Patients and methods: Sham pad effect sizes from 66 control patients in two randomized clinical trials of vibratory stimulation were compared with placebo responses from 1,024 control patients in 12 randomized clinical drug trials reporting subjective sleep measurement scales. Control patient responses were measured as the standardized difference in means corrected for correlation between beginning and ending scores and for small sample sizes. Results: For parallel randomized clinical trials, sham effects in vibratory stimulation trials were not significantly different from placebo effects in drug trials (0.37 and 0.31, respectively, Qbetween subgroups =0.25, PQ≥0.62. Placebo effect sizes were significantly smaller in crossover drug trials than sham effect sizes in parallel vibratory stimulation trials (0.07 versus 0.37, respectively, Qbetween subgroups =4.59, PQ≤0.03 and placebo effect sizes in parallel drug trials (0.07 versus 0.31, respectively, Qbetween subgroups =5.50, PQ≤0.02. Conclusion: For subjective sleep loss assessments in parallel trials, sham pads in vibratory stimulation trials performed similarly to placebo pills in drug trials. Trial design (parallel versus crossover had a large influence on control effect sizes. Placebo pills in crossover drug trials had significantly smaller effect sizes than sham pads in parallel vibratory stimulation trials or placebo pills in parallel drug trials.

To improve the transmitting power in an S-band klystron, a long pill-box window that has a disk with grooves with a semicircular cross section is theoretically investigated and simulated. A Monte-Carlo algorithm is used to track the secondary electron trajectories and analyze the multipactor scenario in the long pill-box window and on the grooved surface. Extending the height of the long-box window can decrease the normal electric field on the surface of the window disk, but the single surface multipactor still exists. It is confirmed that the window disk with periodic semicircular grooves can explicitly suppress the multipactor and predominantly depresses the local field enhancement and the bottom continuous multipactor. The difference between semicircular and sharp boundary grooves is clarified numerically and analytically

Effect of Zataria multiflora on bacterial vaginosis and Trichomonas vaginalis is shown in vivo and in vitro. We compare the effectiveness of Zataria multiflora cream and oral metronidazole pill on results of treatment for vaginal infections including Trichomonas and bacterial vaginosis; these infections occur simultaneously. The study included 420 women with bacterial vaginosis, Trichomonas vaginalis, or both infections together, who were randomly divided into six groups. Criteria for diagnosis were wet smear and Gram stain. Vaginal Zataria multiflora cream and placebo pill were administered to the experiment groups; the control group received oral metronidazole pill and vaginal placebo cream. Comparison of the clinical symptoms showed no significant difference in all three vaginitis groups receiving metronidazole pill and vaginal Zataria multiflora cream. However, comparison of the wet smear test results was significant in patients with trichomoniasis and bacterial vaginosis associated with trichomoniasis in the two treatment groups (p = 0.001 and p = 0.01). Vaginal Zataria multiflora cream had the same effect of oral metronidazole tablets in improving clinical symptoms of all three vaginitis groups, as well as the treatment for bacterial vaginosis. It can be used as a drug for treatment of bacterial vaginosis and elimination of clinical symptoms of Trichomonas vaginitis.

Full Text Available Shexiang Baoxin Pill (SBP originated from a classical TCM Fufang Suhexiang Pill for chest pain with dyspnea in the Southern Song Dynasty (1107–110 AD. Here, we aimed to evaluate preclinical evidence and possible mechanism of SBP for experimental coronary heart disease (CHD. Studies of SBP in animal models with CHD were identified from 6 databases until April 2016. Study quality for each included article was evaluated according to the CAMARADES 10-item checklist. Outcome measures were myocardial infarction area, vascular endothelial growth factor (VEGF and microvessel count (MVC. All the data were analyzed by using RevMan 5.1 software. As a consequence, 25 studies with 439 animals were identified. The quality score of studies ranged from 2 to 5, with the median of 3.6. Meta-analysis of seven studies showed more significant effects of SBP on the reduction of the myocardial infarction area than the control (P < 0.01. Meta-analysis of eight studies showed significant effects of SBP for increasing VEGF expression compared with the control (P < 0.01. Meta-analysis of 10 studies indicated that SBP significantly improved MVC compared with the control (P < 0.01. In conclusion, these findings preliminarily demonstrated that SBP can reduce myocardial infarction area, exerting cardioprotective function largely through promoting angiogenesis.

When can a woman resume or initiate contraception after taking emergency contraceptive pills? A systematic review.

Salcedo, Jennifer; Rodriguez, Maria I; Curtis, Kathryn M; Kapp, Nathalie

2013-05-01

Hormonal emergency contraception can postpone ovulation, making a woman vulnerable to pregnancy later in the same cycle. However, concern exists as to whether concurrently administered emergency contraception pills (ECP) and other hormonal methods of contraception may affect the effectiveness of both medications. A systematic review of the literature using PubMed and the Cochrane databases was performed to identify articles concerning the resumption or initiation of regular contraception within the same cycle as ECP use. We searched for articles in any language, published between 1980 and April 2012 and included all methods of emergency contraception pills available in the USA. The search strategy identified 184 articles in the PubMed and Cochrane databases, of which none met inclusion criteria. The drug manufacturer advises continuation or initiation of routine contraception as soon as possible after use of ulipristal acetate, with concomitant use of a reliable barrier method until next menses. However, a theoretical concern exists that given ulipristal acetate's function as a selective progesterone receptor modulator, coadministration of a progestin could decrease its effectiveness as an emergency contraceptive.

Foreign body impaction in the esophagus amongst adults is not a common cause of dysphagia. Fish bone, food bolus, dentures may cause symptoms of dysphagia, odynophagia, chest pain or respiratory distress. It needs prompt evaluation along with removal of the substance either surgically or endoscopically to avoid the development of life threatening complications. Here we are reporting a case of an elderly male, who presented to us with a history of absolute dysphagia for one week, as a consequence of ingestion of a pill in blister pack. PMID:26918072

Postoperative ileus (POI) is a frequent complication after abdominal surgery (AS). Until today, neither a prophylaxis nor an evidence-based therapy exists. This originates from the absence of objective parameters evaluating the severity and duration of POI resulting in clinical trials of modest quality. The SmartPill(®), a capsule which frequently measures pH value, temperature and intraluminal pressure after swallowing, offers an elegant option for analysing gastrointestinal (GI) transit times and smooth muscle activity in vivo. As the use in patients in the first months after AS is not covered by the marketing authorisation, we aim to investigate the safety and feasibility of the SmartPill(®) immediately after surgery. Additionally, we analyse the influence of prokinetics and laxatives as well as standardised physiotherapy on postoperative bowel contractility, as scientific evidence of its effects is still lacking. The PIDuSA study is a prospective, single-centre, two-arm, open-label trial. The SmartPill(®) will be applied to 55 patients undergoing AS having a high risk for POI and 10 patients undergoing extra-abdominal surgery rarely developing POI. The primary objective is the safety of the SmartPill(®) in patients after surgery on the basis of adverse device effects/serious adverse device effects (ADE/SADE). The sample size suggests that events with a probability of 3% could be seen with a certainty of 80% for at least once in the sample. Secondary objective is the analysis of postoperative intestinal activity in the GI tract in both groups. Furthermore, clinical signs of bowel motility disorders will be correlated to the data measured by the SmartPill(®) to evaluate its significance as an objective parameter for assessing POI severity. Additionally, effects of prokinetics, laxatives and physiotherapy on postoperative peristaltic activity recorded by the SmartPill(®) will be analysed. The protocol was approved by the federal authority (94

As a preparation for long duration space missions it is important to determine and minimize the impact of space radiation on human health. One of the methods to diminish the radiation burden is using an additional local shielding in the places where the crewmembers can stay for longer time. To increase the crew cabin shielding a special protective curtain was designed and delivered to ISS in 2010 containing four layers of hygienic wipes and towels providing an additional shielding thickness of about 8 g/cm"2 water-equivalent matter. The radiation shielding effect of the protective curtain, in terms of absorbed dose, was measured with the thermoluminescent Pille-ISS Detector System. In order to verify the reliability of the Pille system an onboard cross-calibration was also performed. The measurement proved that potentially 25% reduction of the absorbed dose rate in the crew cabin can be achieved, that results in 8% (∼16 μGy/day) decrease of the total absorbed dose to the crew, assuming that they spend 8 h in the crew cabin a day. - Highlights: • The dose level in the ISS Zvezda crew quarters is higher than the average dose level in the module. • A shielding made of hygienic wipes and towels was set up onboard as additional protection. • Onboard cross calibration of the Pille-ISS space dosimeter (TL) system was performed. • The shielding effect of the protective curtain in terms of absorbed dose was measured with the onboard Pille system. • The shielding effect of the protective water curtain is approximately 24 ± 9% in absorbed dose.

The dosimetric properties of a portable TLD reader are described. The TLD system named 'Pille' or 'moth' consists of a lightweight battery-operated portable TLD reader and its CaSO 4 :Dy bulb dosemeters. The reproducibility of the TLD system at constant temperature was found to be better than + -2%, and the mean time between failures exceeded 5 years. The dose range of the system is wide, covering more than 6 orders of magnitude, from 5 μGy to 10 Gy. The energy dependence of the CaSO 4 :Dy bulb dosemeters is less than + - 20% above 100 keV in the energy compensation capsules. Without additional annealing, the bulb dosemeters can be re-used at least 100 times, which is an important aspect during in situ measurements. (author)

Multi-constituent cardiovascular pills (MCCP)--challenges and promises of population-based prophylactic drug therapy for prevention of heart attack.

Science.gov (United States)

Jamieson, Michael J; Naghavi, Morteza

2007-01-01

Risk factors for atherosclerotic cardiovascular disease (CVD) are highly co-prevalent but poorly identified and treated. The Screening for Heart Attack Prevention and Education (SHAPE) Task Force from the Association for Eradication of Heart Attack (AEHA) has recently proposed a new strategy that recommends screening for subclinical atherosclerosis and implementing aggressive treatment of "vulnerable patients". The Task Force has also envisioned future developments that may shift mass screening strategies to mass prophylactic therapy. The "Polypill" concept, introduced by Wald and Law suggests a combination of statin, low-dose antihypertensives, aspirin and folic acid, in a single pill, taken prophylactically by high risk population can cut CVD event rates by as much as 80%. In this communication, we review the challenges and promises of such a strategy. "Polypill" is but one of an astronomical number of possible multiconstituent pills (MCCP). Attractive as the MCCP concept is, it lacks evidence from randomized controlled trials, and begs numerous questions about the credibility of the concept, the design and synthesis of such complex pills, pharmacokinetics, pharmacodynamics, bioequivalence, "class" vs. unique properties, interactions, evidence of clinical efficacy and safety, regulatory approval, post-marketing surveillance, prescription vs. over-the-counter use, responsibility for initiating and monitoring therapy, patient education, counterfeiting and importation, reimbursement, advertisement, patent protection, commercial viability, etc. If these issues are favorably addressed, MCCP stand to dramatically change the manner in which CVD is prevented particularly in developing societies. Notwithstanding, assuming low commercial interests, realizing the promises of MCCP will demand serious attention from national public health policymakers. The clinical and regulatory implications of population-based secondary prevention (which rely on a different evidence base

We present a dynamic equilibrium simulation of the ice sheet-shelf system on Antarctica with the Potsdam Parallel Ice Sheet Model (PISM-PIK). The simulation is initialized with present-day conditions for bed topography and ice thickness and then run to steady state with constant present-day surface mass balance. Surface temperature and sub-shelf basal melt distribution are parameterized. Grounding lines and calving fronts are free to evolve, and their modeled equilibrium state is compared to observational data. A physically-motivated calving law based on horizontal spreading rates allows for realistic calving fronts for various types of shelves. Steady-state dynamics including surface velocity and ice flux are analyzed for whole Antarctica and the Ronne-Filchner and Ross ice shelf areas in particular. The results show that the different flow regimes in sheet and shelves, and the transition zone between them, are captured reasonably well, supporting the approach of superposition of SIA and SSA for the representation of fast motion of grounded ice. This approach also leads to a natural emergence of sliding-dominated flow in stream-like features in this new 3-D marine ice sheet model.

Full Text Available Background: Although emergency contraceptive pills are available over the counter, the quality of consultation, including key areas of contraceptive counseling and prevention of sexually transmitted infections (STI, has not been well documented. Objective: To evaluate actual pharmacist services while dispensing emergency contraception through a mystery shopper technique. Material and Methods: This cross-sectional study was conducted in 81 pharmacies situated in Delhi by 4 trained mystery shoppers posed as customers over a period of 6 months. Results: None of the pharmacists asked about the time lapsed since last unprotected sexual intercourse or last menstrual period before deciding the eligibility of the customer. The majority were unclear about side effects associated with emergency contraception (78.57% or with anticipated changes in menstrual flow (78.57%; 85.71% did not know whether subsequent unprotected intercourse would be protected. Only 15.71% counseled shoppers regarding risk of STI on asking leading questions and 88.5% did not provide any contraceptive advice. Conclusion: There is a huge gap in the technical knowledge and mindset of the pharmacists when it comes to checking for the eligibility of the client and providing advice regarding use of regular contraception and barrier for protection from STI, which needs to be addressed in order to realize the full benefit of making emergency contraceptive pills available over the counter.

This article presents selected findings from a qualitative study of Ecstasy sellers and their sales practices, knowledge of distribution networks, buyer-seller relationships, and self-reported drug use. In-depth interviews were conducted with 80 men and women who had sold five or more hits of Ecstasy five or more times in the six months prior to the interview. Study participants described their perceptions of the various types of Ecstasy they had distributed or used themselves. The participants had experience with a variety of Ecstasy labels, from the popular "Blue Dolphin" tablets to the powdered form called "Molly." We tracked pill brand mentions on Ecstasy-related websites to compare with interviewees' descriptions of Ecstasy brands. This study examines Ecstasy sellers' ideas about the role of brand names in Ecstasy markets and their relationship to their beliefs about different types of Ecstasy's purity and quality. We demonstrate that considering Ecstasy branding increases our understanding of buyer and seller relationships.

Aminzadeh, Atousa; Sabeti Sanat, Ali; Nik Akhtar, Saeed

2016-10-01

Candidiasis, the infection caused by Candida albicans , is one of the most common infections of the oral cavity in humans. Candidiasis causes irritation and is known for its carcinogenic effects. Thus, it is important to recognize the predisposing factors for this opportunistic infection. Several previous studies have demonstrated an increased frequency of vaginal candidiasis in relation to oral contraceptive consumption. Only a few studies on the relation between oral contraceptives and oral candidiasis have been previously conducted. This study aims to evaluate the possible relation between oral contraceptive pills and oral candidiasis. This analytic, case-control study included 40 non-pregnant women divided into two groups: 20 who used oral contraceptive pills and 20 who did not. The groups were matched according to age, oral health, and past and present medical history. Samples were collected from the tongue's dorsum using a cotton swab and inoculated on CHROMagar culture plates. The frequency of positive cultures and the number of Candida colonies were compared between the two groups using independent t-tests and Mann-Whitney statistical tests with SPSS18 software. The frequency of positive cultures of Candida albicans was higher (P value = 0.03) for the case group. Also, the number of C. albicans and C. krusei was significantly higher for the case group compared to the control group (P value = 0.04, P value = 0.03). The results of the present study demonstrate that oral contraceptives containing estradiol can lead to Candida colonization in the oral cavity. It is recommended that further studies comparing the influence of oral contraceptives on Candida's adherence to the epithelium is highly recommended.

Full Text Available Introduction: Acute toxic ingestion is a common cause of morbidity and mortality. Emergency physicians (EP caring for overdose (OD patients are often required to make critical decisions with incomplete information. Point of care ultrasound (POCUS may have a role in assisting EPs manage OD patients. We evaluated the impact of different liquid adjuncts used for gastric decontamination on examiners’ ability to identify the presence of tablets using POCUS, and assessed examiners’ ability to quantify the numbers of tablets in a simulated massive OD. Methods: This prospective, blinded, pilot study was performed at an academic emergency department. Study participants were volunteer resident and staff EPs trained in POCUS. Five non-transparent, sealed bags were prepared with the following contents: 1 liter (L of water, 1 L of water with 50 regular aspirin (ASA tablets, 1 L of water with 50 enteric-coated aspirin tablets (ECA, 1 L of polyethylene glycol (PEG with 50 ECA, and 1 L of activated charcoal (AC with 50 ECA. After performing POCUS on each of the bags using a 10-5 MHz linear array transducer, participants completed a standardized questionnaire composed of the following questions: (1 Were pills present? YES/NO; (2 If tablets were identified, estimate the number (1-10, 11-25, >25. We used a single test on proportions using the binomial distribution to determine if the number of EPs who identified tablets differed from 50% chance. For those tablets identified in the different solutions, another test on proportions was used to determine whether the type of solution made a difference. Since 3 options were available, we used a probability of 33.3%. Results: Thirty-seven EPs completed the study. All (37/37 EP’s correctly identified the absence of tablets in the bag containing only water, and the presence of ECA in the bags containing water and PEG. For Part 2 of the study, most participants - 25/37 (67.5% using water, 23/37 (62.1% using PEG, and

Computer program for calculating the resonant frequency, shunt impedance and quality factor of a pill-box cavity in a storage ring

International Nuclear Information System (INIS)

Aguero, V.M.; Ng, K.Y.

1983-10-01

Keil and Zotter have analyzed the electromagnetic fields excited by the longitudinal density fluctuations of an unbunched relativistic particle beam drifting in a corrugated vacuum chamber of circular cross section. At higher frequencies, these corrugations become resonant cavities. Zotter has written a computer program known as KN7C to compute the resonant frequencies. However, in the actual use of KN7C, some difficulties are encountered. To surmount these difficulties, the program known as CAVITY was written to analyze this pill-box shaped resonant cavity. Although there are many input variables to this program, only two are essential and need to be specified. They are BD = b/d = the ratio of the circular beampipe radius to that of the pill-box cavity and GD = g/d where g is the length of the cavity. When they are specified, CAVITY will print out the dimensionless normalized fundamental resonant frequency FD, shunt impedance Z and figure of merit Q. From these, the actual resonant frequency, shunt impedance and figure of merit can be deduced. The program is described and a listing is provided

Allergic rhinitis is a chronic inflammatory disease of nasal mucosa. Previous studies have shown the therapeutic effects of ketotifen eye drops on allergic conjunctivitis and rhinitis patients. This study was designed to compare the effects of ketotifen drops and oral ketotifen pills on symptoms and quality of life in allergic rhinitis patients. In this double-blind randomized clinical trial, patients with mild allergic rhinitis who were referred to the allergy clinic of Baqiyatallah Hospital from March to April 2014 were randomly allocated to 2 groups; the first group received ketotifen drops (1 drop every 12 hours) with placebo pills (2 pills daily), and the second group received placebo eye drops with ketotifen pills for 4 weeks. Symptoms (sneezing, runny nose, itching, and nasal obstruction) severity were examined and Rhinitis Quality of Life Questionnaire (RQLQ) scores were evaluated in the second and fourth weeks. A total of 140 patients were evaluated in 2 groups. The mean age was 30.33 years. There were no significant differences in demographic data between the groups (p > 0.05). Both groups showed a significant improvement in rhinorrhea, nasal congestion, nasal itching, coughing, sneezing, RQLQ, and nasal smear eosinophil percent compared to baseline amounts (p < 0.05). Improvements were significantly more in the drops group (p < 0.05). Because of the absence of systemic complications in ketotifen eye drops in patients with allergic rhinitis and their easy availability in Iran, using this medication instead of systemic therapies is suggested. Nevertheless, more studies are required to evaluate the long-term effects of using this drug and the recurrence rate of symptoms. © 2015 ARS-AAOA, LLC.

The last decade has seen the emergence of a new phenomenon in recreational substance use with the availability of herbal and synthetic, unregulated, psychoactive drugs in the market place; alongside this, international concern has developed in relation to their use and associated harms. New Zealand (NZ) was one of the first countries to experience this new phenomenon, with products containing chemicals of the piperazine group - mainly benzylpiperazine (BZP) and trifluoromethylphenylpiperazine (TFMPP). In 2008, the NZ Government prohibited these substances, but allowed a 6-month amnesty period for possession. Our study aimed to obtain a measure of change in BZP use over time. This study used a longitudinal, web-based survey, with data collected at two time points from the same participants. The first survey was carried out 3 months after BZP prohibition, and included retrospective questions for the 6 months preceding the survey. The second survey was conducted 9 months after prohibition and also included retrospective questions for the 6 months preceding the survey. 273 sets of paired data were identified. The use of BZP party pills (pparty pills obtained them from friends or from their own stockpiled supplies. The misuse of prescription drugs (p=0.02) increased over time, whereas statistically significant increases in stimulant or alcohol use were not noted. Following prohibition of piperazine-based party pills, we noted a significant reduction in the proportions of participants using them. The observed increase in the misuse of prescription medicines may relate to their perceived 'quality', or as being less 'illegal' than illicit drugs. Copyright © 2013 Elsevier B.V.

Full Text Available Objective: To study the effect of Qianggan Pills combined with antiviral treatment on the fibrosis indexes, immune and inflammatory response in patients with compensated hepatitis b cirrhosis. Methods: A total of 88 patients with compensated hepatitis b cirrhosis treated in our hospital between April 2013 and March 2016 were collected and divided into observation group and control group according to single blind randomized control. Observation group of patients accepted Qianggan Pills combined with antiviral treatment and control group of patients received antiviral treatment alone. After 6 months of treatment, chemiluminescence method was used to detect serum fibrosis indexes, flow cytometer was used to detect peripheral blood T lymphocyte subset levels, and enzyme-linked immunosorbent assay (ELISA was used to detect serum levels of inflammatory factors. Results: Before treatment, differences in fibrosis indexes, immune and inflammatory response indexes were not statistically significant between two groups of patients; after 6 months of treatment, serum LN, HA and Ⅳ-C levels of observation group were lower than those of control group, peripheral blood CD3+ and CD4+ T lymphocyte levels as well as CD4+/CD8+ ratio were higher than those of control group, and CD8+ T lymphocyte level was lower than that of control group; serum PCT and CRP levels were lower than those of control group while IL-10 and IL-13 levels were higher than those of control group. Conclusion: Qianggan Pills combined with antiviral treatment can inhibit the fibrosis process, strengthen the body's immune function and also relieve systemic inflammatory response in patients with compensated hepatitis b cirrhosis.

To compare the efficacy of two kinds of Zhizhu pills in the treatment of functional dyspepsia of spleen-deficiency and qi-stagnation syndrome:a randomized group sequential comparative trial

Science.gov (United States)

2011-01-01

Background In Traditional Chinese Medicine (TCM) theory, functional dyspepsia (FD) can be divided into different syndromes according to different clinical symptoms and signs, and the most common one is spleen-deficiency and qi-stagnation syndrome that can be treated by Chinese traditional patent medicine ---- two kinds of Zhizhu pills, between which the primary difference in ingredients is that one contains immature orange fruit of Citrus aurantium L.(IFCA) and the other contains that of Citrus sinensis Osbeck (IFCS). The trial's objective was to compare the efficacy of two kinds of Zhizhu pills on symptom changes in patients with FD of spleen-deficiency and qi-stagnation syndrome. Methods A randomized, group sequential, double-blinded, multicenter trial was conducted in patients with FD of spleen-deficiency and qi-stagnation syndrome at 3 hospitals in Beijing between June 2003 and May 2005. Participants were randomly allocated into two groups (IFCA group and IFCS group) in a 1:1 ratio, and respectively took one of the two kinds of Zhizhu pills orally, 6 g each time, 3 times a day, for 4 weeks. Statistical analysis was performed with use of a group sequential method, the triangular test (TT). Results A total of 163 patients were randomized, and 3 patients were excluded from analysis because of early dropouts, leaving 160 patients (IFCA group: n = 82; IFCS group: n = 78) for statistical analysis. Three interim analyses were done after 62, 116, and 160 patients had completed their 4-week treatment, respectively. At the third interim analysis, the sample path crossed the upper boundary and the trial was stopped, the cure-markedly effective rates were 45% for IFCS group and 67% for IFCA group, respectively, the one-sided p-value was 0.0036, the median unbiased estimate of the odds ratio (OR) for the benefit of IFCA relative to IFCS was 2.91 with 95%CI: 1.40 to 6.06. No adverse events were observed in the two groups. Conclusions Zhizhu pills containing IFCA was superior

Sixty clean healthy male Sprague-Dawley (SD) rats were randomly divided into sham operation group, model group and observation group (each n = 20). The rat model of acute myocardial infarction (AMI) was established by ligation of left anterior descent (LAD) branch of coronary artery. After modeling, the rats in observation group were given 0.135 g/kg of Qishen Yiqi dropping pills, and sham operation group and model group were administered the same amount of normal saline, once a day for consecutive 28 days. At the end of treatment, the levels of serum inflammatory factors of leukotriene B4 (LTB4), prostaglandin E 2 (PGE 2 ), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) were measured by enzyme linked immunosorbent assay (ELISA); the changes of the indexes of hemodynamic [left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), the maximal rate of increase/decrease in left ventricular pressure (±dp/dt max)], the ratio of the heart weight/body weight, and the ratio of the left ventricular weight/heart weight (LVW/HW), the myocardial infarction area, myocardial histopathological changes were observed in the three groups; myocardial tissues inflammatory related factors [the mRNA and protein expressions of cytosolic phospholipase A2 (cPLA2), cyclooxygenase-2 (COX-2), 5-lipoxygenase (5-LOX)], and the expression levels of transforming growth factor-β (TGF-β)/Smads signal transduction pathway related protein (TGF-β1, Smad2/3, Collagen I, Collagen III) and cell apoptosis related factors (Bcl-2, Bax) protein were measured. Compared with the sham operation group, levels of serum inflammatory factors, the index of LVEDP, the ratio of the heart weight/body weight, LVW/HW, myocardial infarction area, the mRNA and protein expression levels of inflammatory factors in myocardium, the expression levels of

In 2010, the iPrEx study demonstrated efficacy of daily emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) pre-exposure prophylaxis (PrEP) in reducing HIV acquisition among men who have sex with men. Adherence to study product was critical for PrEP efficacy, and varied considerably, with FTC/TDF detection rates highest in the United States. We conducted a qualitative study to gain insights into the experiences of iPrEx participants in San Francisco (SF) where there was high confirmed adherence, to understand individual and contextual factors influencing study product use in this community. In 2009 and 2011, we conducted focus groups and in-depth interviews in 36 and 16 SF iPrEx participants, respectively. Qualitative analyses indicate that participants joined the study out of altruism. They had a clear understanding of study product use, and pill taking was facilitated by establishing or building on an existing routine. Participants valued healthcare provided by the study and relationships with staff, whom they perceived as nonjudgmental, and found client-centered counseling to be an important part of the PrEP package. This facilitated pill taking and accurate reporting of missed doses. Adherence barriers included changes in routine, side effects/intercurrent illnesses, and stress. Future PrEP adherence interventions should leverage existing routines and establish client-centered relationships/ environments to support pill taking and promote accurate reporting.

To observe the effect of Liuweidihuang Pills in relieving cellphone electromagnetic radiation-induced histomorphological abnormality, oxidative injury, and cell apoptosis in the rat testis. Thirty adult male SD rats were equally randomized into a normal, a radiated, and a Liuweidihuang group, the animals in the latter two groups exposed to electromagnetic radiation of 900 MHz cellphone frequency 4 hours a day for 18 days. Meanwhile, the rats in the Liuweidihuang group were treated with the suspension of Liuweidihuang Pills at 1 ml/100 g body weight and the other rats intragastrically with the equal volume of purified water. Then all the rats were killed for observation of testicular histomorphology by routine HE staining, measurement of testicular malondialdehyde (MDA) and glutathione (GSH) levels by colorimetry, and determination of the expressions of bax and bcl-2 proteins in the testis tissue by immunohistochemistry. Compared with the normal controls, the radiated rats showed obviously loose structure, reduced layers of spermatocytes, and cavitation in the seminiferous tubules. Significant increases were observed in the MDA level (P radiated rats. In comparison with the radiated rats, those of the Liuweidihuang group exhibited nearly normal testicular structure, significantly lower MDA level (P electromagnetic radiation-induced histomorphological abnormality of the testis tissue and reduce its oxidative damage and cell apoptosis.

Water-soluble Cistanche phenylethanoid glycosides (CPhGs) have poor permeability and low bioavailability. However, liposomes can improve the permeability of such drugs and their poor stability, and proliposomes have been used to overcome these problems. Based on this, Cistanche phenylethanoid glycoside liquid proliposomes (CPhGsP) and dripping(?) pills were prepared and optimized using response surface methodology. The properties of CPhGsP were evaluated in terms of their encapsulation efficiency, particle size, zeta potential, and morphology. The results obtained showed that the optimal formulation was drug/soybean phospholipid/poloxamer-188/sodium deoxycholate/propylene glycol 1:22.38:3.52:0.84:80 (w/w/w/w/v). This resulted in an encapsulation efficiency, particle size, and zeta potential of hydrated proliposomes with phosphate buffer solution (pH7.4) of 51.97%, 671.7nm, and -25.49mV, respectively. Stability testing of CPhGsP and CPhGs ordinary liposomes was carried out for 3months at 4±2°C, 25±2°C, 40±2°C, 75±5% RH. The results obtained showed that the stability of the proliposomes was better than that of ordinary liposomes at the same temperature, while a lower temperature of 4°C is ideal for storage. Cistanche phenylethanoid glycoside liquid proliposomes dripping pills (CPhGsPD) are efficiently released in gastrointestinal solution as shown by in vitro release experiments and the structure of the liposomes does not destroy the proliposome dripping pills by hydration. In vivo experiments showed that the areas under the plasma level-time curves and peak concentrations of CPhGsPD and hydrated proliposomes were higher than those of CPhGs. Moreover, with CPhGsPD, the pharmacokinetic parameters were similar to those with hydrated proliposomes. These results showed that CPhGsPD offer a good way to improve the oral delivery of CPhGs.

A gas scintillation proportional counter of 'pill-box' design operated with argon + 2.5% nitrogen gas in continuous flow, has been developed. An energy resolution of 1.6% is obtained for 239 Pu α-particles emitted from a mixed nuclide source of 239 Pu- 241 Am- 244 Cm and injected into the counter parallel to the anode. The risetime of the scintillation pulse is found to be less than 0.5 μs. Measurements have been made of charge and light gain factors as a function of anode voltage. It is found that for a given anode voltage, the scintillation pulse amplitude increases sharply with the addition of nitrogen to argon and reaches a maximum at about 2.5% and then decreases slowly, whereas the charge pulse amplitude reduces monotonically. Nitrogen improvement factors with the addition of 2.5% nitrogen to argon are found to be different for two photomultipliers with different photocathode responses. The improvement in energy resolution as a result of addition of nitrogen to argon is discussed. Comments are made on the intrinsic energy resolution capabilities of such a counter. (orig.)

Much literature surrounding medical technology and adherence posits that technology is a mechanism for social control. This assumes that the medical establishment can take away patients' agency. Although power relationships and social control can play a key role, medical technology can also serve as an agentive tool to be utilized. We (1) offer the alternative framework of Actor Network Theory to view medical technology, (2) discuss the literature on medication adherence and technology, (3) delve into the ramifications of looking at adherence as a network and (4) use Digital Pills as a case study of dispersed agency. © 2015 John Wiley & Sons Ltd.

Negative non-specific (nocebo-like) effects of medications and electromagnetic fields are often described as results of mistaken attribution. The current study aimed to find empirical evidence supporting this theory. Participants completed questionnaires assessing modern health worries, health anxiety, and somatosensory amplification, were assigned to one of three conditions (placebo pill with sedative information, sham magnetic field, or control), and completed a 14-min vigilance task. Changes in physiological arousal (heart rate, heart rate variability, and skin conductance) and reported symptoms were also measured. Finally, causal attributions concerning cognitive performance and reported symptoms were assessed. No increase in symptom reports and physiological arousal was measured in the two intervention groups. A perceived negative effect on cognitive performance was attributed to both sham conditions, and attributions were connected to modern health worries. A proportion of reported symptoms was ascribed to the placebo pill but not to the sham magnetic field. Symptom attributions were not related to any assessed psychological variables. An aroused physiological state is not necessary for the automatic causal attribution process. Negative effects attributed to medication and environmental factors can be regarded as unavoidable side effects of human cognitive-emotional functioning; they might be alleviated, but cannot be completely eradicated.

Opioid abuse is a growing problem in civilian communities, and it has developed in the military as well. Telephone calls to poison centers requesting pill identification (ID) is a marker of drug abuse. This study identifies the number of pill ID calls made to the poison centers from areas containing and surrounding three Texas military bases during an 8-year period. We performed a retrospective observational study identifying calls to certified poison centers in Texas from 2002 to 2009 that identified hydrocodone tablets and other pain medications. We noted the calls made from ZIP codes containing and surrounding the three largest military bases in Texas. We reviewed 75,537 drug ID calls for any drug from the ZIP codes of interest. Total drug ID calls increased 105% and the number of calls for hydrocodone increased 463%. In our study most of the drug ID calls from military communities in Texas were for hydrocodone. The rate of calls for hydrocodone increased more than the rate of calls for other analgesics from 2002 to 2009. Using drug ID calls as a surrogate of drug abuse, our results suggest that hydrocodone abuse has increased within military communities and that poison center data can be a reliable surrogate for prescription drug abuse near military bases. Future studies are needed to further understand the extent of this problem in military and civilian communities. We can use this information to heighten awareness, influence prescription practices, establish practice guidelines, and develop educational programs to mitigate the increasing rate of prescription analgesic abuse in the United States.

Workers in Mexico's maquiladoras (assembly plants) are mainly young, single women, many of whom could benefit from emergency contraceptive pills (ECPs). Because ECPs are readily available in Mexico, women who know about the therapy can obtain it easily. Do maquiladora workers know about the method? Could worksite programs help increase awareness? To investigate these questions, we conducted a five-month intervention during which workers in three maquiladoras along the Mexico-United States border could attend educational talks on ECPs, receive pamphlets, and obtain kits containing EC supplies. Among the workers exposed to our intervention, knowledge of ECPs increased. Reported ECP use also increased. Although our intervention apparently increased workers' knowledge and use, the factory proved to be a difficult intervention setting. Problems we experienced included a factory closure and management/staff opposition to certain project elements. Future studies should continue to investigate work-site interventions and other strategies to reach workers.

Full Text Available Lesley L Breech, Paula K BravermanDivision of Adolescent Medicine, Department of Pediatrics, Cincinnati Children’s Hospital Medical Center, University of Cincinnati College of Medicine, Cincinnati, OH, USAAbstract: Premenstrual dysphoric disorder (PMDD is estimated to affect 3%–8% of reproductive age women. Multiple therapeutic modalities have been evaluated with varying efficacy for the associated somatic and mood symptoms. The majority of older studies had shown that oral contraceptive pills (OCs were most effective for the physical symptoms. However, newer OCs containing a novel progestin, drospirenone, have shown promise in alleviating both the somatic and affective/behavioral symptoms. This progestin, which is a derivative of spironolactone, has both antimineralocorticoid and antiandrogenic activity. A 24/4 formulation containing 20 µg of ethinyl estradiol has been found effective in randomized double-blind placebo-controlled trials utilizing established scales documenting symptoms associated with PMDD. Multiple studies have shown that drospirenone-containing OCs are safe without evidence of clinically adverse effects on carbohydrate metabolism, lipids, blood pressure, weight, serum potassium or increased thrombotic events compared to other low dose OCs. In addition, significant improvements have been demonstrated in acne, hirsutism, and fluid retention symptoms. Several open label studies demonstrated good patient compliance and reported satisfaction with the method. Because of the significant placebo effect demonstrated in the blinded placebo-controlled trials, additional large randomized placebo-controlled trials are needed to confirm the efficacy of the drospirenone OCs in the treatment of PMDD. However, this OC formulation appears to be a promising therapeutic modality.Keywords: drospirenone, premenstrual dysphoric disorder, premenstrual syndrome, oral contraceptive pill

Can combining different risk interventions into a single formulation contribute to improved cardiovascular disease risk reduction? The single pill of amlodipine/atorvastatin

Full Text Available FD Richard HobbsUniversity of Birmingham, Edgbaston, Birmingham B15 2TT, UK.Abstract: In order to prevent cardiovascular events, it is essential to effectively manage overall risk of cardiovascular disease. However, despite guideline recommendations to this effect, current management of the major, modifiable cardiovascular risk factors such as hypertension and dyslipidemia is disconnected and patient adherence to therapy is poor. This is particularly important for patients with multiple cardiovascular risk factors, who are often prescribed multiple medications. The JEWEL study program investigated the use of single-pill amlodipine/atorvastatin as a strategy to improve management of these patients. The JEWEL program consisted of two 16-week, international, openlabel, multicenter, titration-to-goal studies in patients with hypertension and dyslipidemia. The two studies differed based on country of enrollment and certain tertiary endpoints, but the overall designs were very similar. Patients were enrolled from 255 centers across Canada and 13 European countries. The study was designed to assess the efficacy, safety, and utility of amlodipine/atorvastatin single pill therapy in a real-world setting. Patients were initiated at a dose of amlodipine 5 mg/atorvastatin 10 mg, unless previously treated, and were uptitrated as necessary. The primary efficacy parameter was the percentage of patients, at different levels of cardiovascular risk, achieving country-specific guideline-recommended target levels for blood pressure and lipids. A secondary analysis of efficacy measured attainment of the same single goal for blood pressure across all study participants (JEWEL I and II and the same single goal for LDL-C across all study participants (JEWEL I and II. The program utilized a newly developed questionnaire to gain better understanding of participants’ beliefs and behaviors towards medical treatment of their multiple risk factors. Approximately 2850

GLYCINE-RICH RNA-BINDING PROTEIN1 interacts with RECEPTOR-LIKE CYTOPLASMIC PROTEIN KINASE1 and suppresses cell death and defense responses in pepper (Capsicum annuum).

Plants use a variety of innate immune regulators to trigger cell death and defense responses against pathogen attack. We identified pepper (Capsicum annuum) GLYCINE-RICH RNA-BINDING PROTEIN1 (CaGRP1) as a RECEPTOR-LIKE CYTOPLASMIC PROTEIN KINASE1 (CaPIK1)-interacting partner, based on bimolecular fluorescence complementation and coimmunoprecipitation analyses as well as gene silencing and transient expression analysis. CaGRP1 contains an N-terminal RNA recognition motif and a glycine-rich region at the C-terminus. The CaGRP1 protein had DNA- and RNA-binding activity in vitro. CaGRP1 interacted with CaPIK1 in planta. CaGRP1 and CaGRP1-CaPIK1 complexes were localized to the nucleus in plant cells. CaPIK1 phosphorylated CaGRP1 in vitro and in planta. Transient coexpression of CaGRP1 with CaPIK1 suppressed the CaPIK1-triggered cell death response, accompanied by a reduced CaPIK1-triggered reactive oxygen species (ROS) burst. The RNA recognition motif region of CaGRP1 was responsible for the nuclear localization of CaGRP1 as well as the suppression of the CaPIK1-triggered cell death response. CaGRP1 silencing in pepper conferred enhanced resistance to Xanthomonas campestris pv vesicatoria (Xcv) infection; however, CaPIK1-silenced plants were more susceptible to Xcv. CaGRP1 interacts with CaPIK1 and negatively regulates CaPIK1-triggered cell death and defense responses by suppressing ROS accumulation. © 2014 The Authors.

Decoupling of the PI3K Pathway via Mutation Necessitates Combinatorial Treatment in HER2+ Breast Cancer.

Directory of Open Access Journals (Sweden)

James E Korkola

Full Text Available We report here on experimental and theoretical efforts to determine how best to combine drugs that inhibit HER2 and AKT in HER2(+ breast cancers. We accomplished this by measuring cellular and molecular responses to lapatinib and the AKT inhibitors (AKTi GSK690693 and GSK2141795 in a panel of 22 HER2(+ breast cancer cell lines carrying wild type or mutant PIK3CA. We observed that combinations of lapatinib plus AKTi were synergistic in HER2(+/PIK3CA(mut cell lines but not in HER2(+/PIK3CA(wt cell lines. We measured changes in phospho-protein levels in 15 cell lines after treatment with lapatinib, AKTi or lapatinib + AKTi to shed light on the underlying signaling dynamics. This revealed that p-S6RP levels were less well attenuated by lapatinib in HER2(+/PIK3CA(mut cells compared to HER2(+/PIK3CAwt cells and that lapatinib + AKTi reduced p-S6RP levels to those achieved in HER2(+/PIK3CA(wt cells with lapatinib alone. We also found that that compensatory up-regulation of p-HER3 and p-HER2 is blunted in PIK3CA(mut cells following lapatinib + AKTi treatment. Responses of HER2(+ SKBR3 cells transfected with lentiviruses carrying control or PIK3CA(mut sequences were similar to those observed in HER2(+/PIK3CA(mut cell lines but not in HER2(+/PIK3CA(wt cell lines. We used a nonlinear ordinary differential equation model to support the idea that PIK3CA mutations act as downstream activators of AKT that blunt lapatinib inhibition of downstream AKT signaling and that the effects of PIK3CA mutations can be countered by combining lapatinib with an AKTi. This combination does not confer substantial benefit beyond lapatinib in HER2+/PIK3CA(wt cells.

Class III phosphoinositide 3-kinase (PIK3C3 or mammalian vacuolar protein sorting 34 homolog, Vps34) regulates vesicular trafficking, autophagy, and nutrient sensing. Recently, we reported that PIK3C3 is expressed in mouse cerebral cortex throughout the developmental process, especially at early embryonic stage. We thus examined the role of PIK3C3 in the development of the mouse cerebral cortex. Acute silencing of PIK3C3 with in utero electroporation method caused positional defects of excitatory neurons during corticogenesis. Time-lapse imaging revealed that the abnormal positioning was at least partially because of the reduced migration velocity. When PIK3C3 was silenced in cortical neurons in one hemisphere, axon extension to the contralateral hemisphere was also delayed. These aberrant phenotypes were rescued by RNAi-resistant PIK3C3. Notably, knockdown of PIK3C3 did not affect the cell cycle of neuronal progenitors and stem cells at the ventricular zone. Taken together, PIK3C3 was thought to play a crucial role in corticogenesis through the regulation of excitatory neuron migration and axon extension. Meanwhile, when we performed comparative genomic hybridization on a patient with specific learning disorders, a 107 Kb-deletion was identified on 18q12.3 (nt. 39554147-39661206) that encompasses exons 5-23 of PIK3C3. Notably, the above aberrant migration and axon growth phenotypes were not rescued by the disease-related truncation mutant (172 amino acids) lacking the C-terminal kinase domain. Thus, functional defects of PIK3C3 might impair corticogenesis and relate to the pathophysiology of specific learning disorders and other neurodevelopmental disorders. Acute knockdown of Class III phosphoinositide 3-kinase (PIK3C3) evokes migration defects of excitatory neurons during corticogenesis. PIK3C3-knockdown also disrupts axon outgrowth, but not progenitor proliferation in vivo. Involvement of PIK3C3 in neurodevelopmental disorders might be an interesting future

We have substantially damped the higher order modes (HOM's) in a pill box cavity with attached beam pipe, while reducing the Q of the principal mode by less that 10%. This was accomplished by cutting slots in the cavity end wall at a radius at which the magnetic field of the lowest frequency HOM's is large. The slots couple energy from the cavity into waveguides which are below cut off for the principal mode, but which propagate energy at the HOM frequencies. Three slots 120 degrees apart couple HOM energy to three waveguides. We are concerned primarily with accelerating and deflecting modes: i.e. the TM mnp modes of order m=0 and m=1. For the strongest damping, only three m=0 and m=1 modes were detectable. These were the principal TM 010 mode, the TM 011 longitudinal mode, and the TM 110 deflecting mode. In addition the HOM Q's and the reduction of Q for the principal mode were determined by computer calculation. The principal mode Q for an actual rf cavity could not be measured because the bolted joints used in the construction of the cavity were not sufficiently good to support Q's above 6000. The measured Q of the first longitudinal mode was 31 and of the first transverse mode 37. Our maximum damping was limited by how well we could terminated the waveguides, and indeed, the computer calculations for the TM 011 and TM 110 modes give values in the range we measured. 2 refs., 2 figs

Improved Design and Fabrication of Hydrated-Salt Pills

A high-performance design, and fabrication and growth processes to implement the design, have been devised for encapsulating a hydrated salt in a container that both protects the salt and provides thermal conductance between the salt and the environment surrounding the container. The unitary salt/container structure is known in the art as a salt pill. In the original application of the present design and processes, the salt is, more specifically, a hydrated paramagnetic salt, for use as a refrigerant in a very-low-temperature adiabatic demagnetization refrigerator (ADR). The design and process can also be applied, with modifications, to other hydrated salts. Hydrated paramagnetic salts have long been used in ADRs because they have the desired magnetic properties at low temperatures. They also have some properties, disadvantageous for ADRs, that dictate the kind of enclosures in which they must be housed: Being hydrated, they lose water if exposed to less than 100-percent relative humidity. Because any dehydration compromises their magnetic properties, salts used in ADRs must be sealed in hermetic containers. Because they have relatively poor thermal conductivities in the temperature range of interest (<0.1 K), integral thermal buses are needed as means of efficiently transferring heat to and from the salts during refrigeration cycles. A thermal bus is typically made from a high-thermal-conductivity met al (such as copper or gold), and the salt is configured to make intimate thermal contact with the metal. Commonly in current practice (and in the present design), the thermal bus includes a matrix of wires or rods, and the salt is grown onto this matrix. The density and spacing of the conductors depend on the heat fluxes that must be accommodated during operation.

A curious abnormally developed embryo of the pill millipede Glomeris marginata (Villers, 1789

Full Text Available This paper reports on an abnormally developed embryo (ADE of the common pill millipede Glomeris marginata. This ADE represents a modified case of Duplicitas posterior, in which two posterior ends are present, but only one anterior end. While the major posterior germ band of the embryo appears almost normally developed, the minor posterior germ band is heavily malformed, has no clear correlation to the single head, little or no ventral tissue, and a minute amount of yolk. The anterior end of the minor germ band is fused to the ventral side of the major germ band between the first and second trunk segment. At least one appendage of the second trunk segment appears to be shared by the two germ bands. Morphology and position of the minor germ band suggest that the ADE may be the result of an incorrectly established single cumulus [the later posterior segment addition zone (SAZ]. This differs from earlier reports on D. posterior type ADEs in G. marginata that are likely the result of the early formation of two separate cumuli.

The Use Of Oral Ranolazine To Convert New Or Paroxysmal Atrial Fibrillation: A Review Of Experience With Implications For Possible "Pill In The Pocket" Approach To Atrial Fibrillation

Directory of Open Access Journals (Sweden)

David K Murdock

2009-09-01

Full Text Available Background: Atrial fibrillation (AF is the most common arrhythmia requiring treatment. High dose oral anti-arrhythmics may cardiovert some paroxysmal AF. This "pill in pocket" approach has allowed patients to treat themselves on an as needed basis. Pro-arrhythmic concerns have limited the usefulness of this approach to patients without structural heart disease. Ranolazine is an anti-anginal agent, which inhibits abnormal late Na+ channel currents in cardiomyocytes and decreases sodium-calcium overload. Ranolazine is a potent inhibitor of after-depolarizations, which have been implicated in the initiation and propagation of AF. Because ranolazine has no known pro-arrhythmic effects, it could be useful as a safe "pill in the pocket" agent if it were effective in converting AF. We describe our experience using oral ranolazine to convert new or paroxysmal AF. Method: 2000 mg of ranolazine were administered to 18 patients with new (11 patients or paroxysmal (7 patients AF of at least 3, but not greater than 48 hours duration. Most patients (14 were in the hospital at the time ranolazine was administered. Age, sex, echocardiographic data, associated health conditions and structural heart disease were recorded. Successful conversion was defined as restoring sinus rhythm within 6 hours of ranolazine administration. Results: All but 1 patient had some form of structural heart disease and all but 2 patients had left atrial enlargement. Thirteen of 18 patients converted to sinus rhythm. No pro-arrhythmic effects, hemodynamic instability, adverse rate effects, or perceived intolerance (other than constipation were noted. The 72% conversion rate was comparable to other reported "pill in the pocket" protocols. Conclusion: High dose oral ranolazine shows utility as a possible safe agent to convert new or paroxysmal AF. Lack of blinded controls and small numbers limits the power of this observation.

The aim of this study was to compare combined hormonal vaginal ring with ultralow-dose combined oral contraceptive (COC) pills in management of heavy menstrual bleeding (HMB). Fifty patients were randomised into Group I: vaginal ring (n = 25) and group II: COC pills (n = 25). Menstrual blood loss (MBL) was assessed at baseline, 1, 3 and 6 months (while on treatment) and at 9 months (3 months after stopping therapy). There was significant reduction in baseline pictorial blood loss assessment chart (PBAC) score from 440 ± 188 (Mean ± SD) to 178 ± 95, 139 ± 117, 112 ± 84 and 120 ± 108 in group I and from 452 ± 206 to 204 ± 152, 179 ± 125, 176 ± 164 and 202 ± 167 in group II at 1, 3, 6 and 9 months, respectively (p = 0.001). Reduction in MBL was 72% and 62% at 6 months and up to 71% and 55% at 9 months in group I and group II, respectively (p = 0.001). Reduction in MBL with ring was greater at higher baseline PBAC score but lesser in patients with fibroid > 2 cm. Combined vaginal hormonal treatment for HMB is as effective as oral hormonal therapy, with minor and transient side effects and persistence of response after cessation of therapy.

A sensitive, specific, accurate HPLC-MS/MS method was developed and validated for the simultaneous quantification of catechin, epicatechin, liquiritin, isoliquiritin, liquiritigenin, isoliquiritigenin, piperine and glycyrrhetinic acid from Longhu Rendan pills in rat plasma. Chromatographic separation was performed with a Hypersil Gold C18 column using a gradient of methanol and 0.01% acetic acid containing 0.2 mm ammonium acetate as mobile phase. The analytes were quantified on a triple quadrupole mass spectrometer, operating in selected reaction monitoring mode and switching the electrospray ion source polarity between positive and negative modes in a single run. The calibration curves of catechin, epicatechin, liquiritin, isoliquiritin, liquiritigenin, isoliquiritigenin, piperine and glycyrrhetinic acid were linear over the concentration ranges of 5-2000, 5-2000, 0.5-200, 0.5-200, 0.25-100, 0.25-100, 0.025-10 and 0.50-200 ng mL(-1) , respectively. The intra- and inter-assay precisions and accuracies were pills to rats. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Severe Erosive Pill Esophagitis Induced by Crizotinib Therapy: A Case Report and Literature Review

Directory of Open Access Journals (Sweden)

Patrick Jung

2016-01-01

Full Text Available Previous case reports have described esophagitis thought to be secondary to crizotinib, an oral tyrosine-kinase inhibitor used in the treatment of anaplastic lymphoma kinase- (ALK- positive non-small cell lung cancer (NSCLC. In those reports, the interval development of esophagitis was between two days and three months after initiating or reinitiating crizotinib therapy. We present a woman who developed ulcerative esophagitis ten months after beginning crizotinib therapy, which is highly unusual. We believe the provoking factor was a change in her medication administration routine, done to accommodate religious practices during the period of Ramadan. This case illustrates the mechanism of pill esophagitis and reinforces the importance of patient education when it comes to medication administration. Clinicians may consider early imaging or investigations in patients with concerning symptomatology in the context of crizotinib therapy or other offending medications. Future research may help to uncover additional risk factors for this exceedingly rare diagnosis in this patient population. Most importantly, this case highlights nonpharmacologic ways to improve tolerability and decrease adverse effects of a highly effective chemotherapeutic agent.

Antiplatelet Effects of Qishen Yiqi Dropping Pill in Platelets Aggregation in Hyperlipidemic Rabbits

Full Text Available We investigated the effects of Qishen Yiqi Dropping Pill (QSYQ on platelets aggregation and its possible mechanisms. Hyperlipidemic model in rabbits was produced by a high fat/cholesterol diet for 6 weeks, the therapeutic effect of QSYQ with 2.0 g/kg, 1.0 g/kg, and 0.5 g/kg was observed. Fourteen days after drug treatment, platelet aggregation induced by adenosine diphosphate (ADP, arachidonic acid (AA, and collagen (COLL was significantly reduced in rabbits of model group. Moreover, β-thromboglobulin (β-TG level decreased obviously but no significant change in P-selectin and platelet factor 4 (PF4 level, while QSYQ significantly decreased the ratio of thromboxane B2 (TXB2 to 6-keto-prostaglandin F1α (6-Keto-PGF1α and increased cyclic adenosine monophosphate (cAMP level in rabbits. In summary, QSYQ can improve platelets aggregation and inhibit the over-release of β-TG in hyperlipidemic rabbits; and the increased cAMP level may be involved in this process. These results suggest that the antiplatelet aggregation effect of QSYQ may be due to its ability to increase cAMP level for improving cAMP metabolism.

To investigate the clinical effect of Gushen Antai pills and progesterone in the treatment of threatened abortion, in order to provide references for early clinical intervention with threatened abortion. The 112 cases of patients with threatened abortion were randomly divided into the control group and the observation group. 56 cases in each group. Patients in the control group was injected with progesterone, the observation group was treated with Gushen Antai pills in addition to the therapy of the control group. Both groups were treated by drugs for two weeks. Their venous bloods (5 mL) were collected before treatment and in 1, 2 weeks after treatment to determine serum levels of β-HCG, P, E2 and CA125. The differences between the two groups after treatment were compared. The total effective rate of the control group and the observation group were 79% and 91.9% respectively, with a statistically significant difference between the two groups (P＜0.05). Two weeks after the treatment, the serum levels of P and E2 in the observation group were significantly higher than before treatment, but the serum CA125 levels decreased significantly after treatment (Ppills and progesterone had a better clinical curative effect in treatment threatened abortion, which could significantly raise serum β-HCG, P and E2, reduce serum CA125 and increase the tocolysis efficiency, and so it was worth promoted in clinic.

Arterial stiffness is associated with increased cardiovascular disease risk. Previous sex-based investigations of local and central stiffness report inconsistent findings and have not controlled for menstrual cycle phase in women. There is also evidence that sex hormones influence the vasculature, but their impact on arterial stiffness across a natural menstrual (NAT) or oral contraceptive pill (OCP) cycle has been understudied. This study sought to 1) examine potential sex differences in local and central stiffness, 2) compare stiffness profiles between NAT and OCP cycles, and 3) investigate the relationship between duration of OCP use and arterial stiffness. Fifty-three healthy adults (22{plus minus}3 years; 20 men, 15 NAT, 18 OCP) underwent assessments of sex hormone concentrations, β-stiffness index (local stiffness), and carotid-femoral pulse wave velocity (cfPWV, central stiffness). All participants were tested three times (men: same day and time one week apart; NAT: menstrual, mid-follicular, luteal; OCP: placebo, early and late active pill). Men had higher β-stiffness than NAT and OCP (p0.05 for all) and were not associated with duration of OCP use (β-stiffness: r=0.003, p=0.99; cfPWV: r =-0.26, p=0.30). The apparent sex-differences in local, but not central stiffness highlight the importance of assessing both indices when comparing men and women. Furthermore, fluctuating sex hormones do not appear to influence β-stiffness or cfPWV. Therefore, these stiffness indices may only need to be assessed during one cycle phase in women in future investigations.

Ekstrand, Anna Isinger; Jönsson, Mats; Lindblom, Annika

2010-01-01

The phosphatidylinositol 3-kinases-AKT-mammalian target of rapamycin pathway (PI3K/AKT/mTOR) is central in colorectal tumors. Data on its role in hereditary cancers are, however, scarce and we therefore characterized mutations in PIK3CA and KRAS, and expression of PIK3CA, phosphorylated AKT......, and PTEN in colorectal cancers linked to hereditary nonpolyposis colorectal cancer (HNPCC). Sequencing was used to identify mutations in PIK3CA, a real-time PCR-based method to identify KRAS mutations, and immunohistochemical staining was used to evaluate the expression of PIK3CA, phosphorylated AKT...... and PTEN in 58 HNPCC-associated colorectal cancers. Derangements of at least one of the PI3K/AKT/mTOR components analyzed were found in 51/58 (88%) tumors. Mutations in PIK3CA and KRAS were identified in 14 and 31% of the tumors respectively. Overexpression of PIK3CA and phosphorylated AKT occurred in 59...

An apparently non-swinging tentorium in the Diplopoda (Myriapoda: comparative morphology of the tentorial complex in giant pill-millipedes (Sphaerotheriida

Directory of Open Access Journals (Sweden)

Leif Moritz

2018-03-01

Full Text Available The presence of a swinging tentorium is a key apomorphy of Myriapoda, but this character has been studied in detail in only few species. Here the tentorium, i.e., the peristomatic skeleton of the preoral chamber, is comparatively studied in three species of the millipede order Sphaerotheriida Brandt, 1833. Since dissections of the fragile tentorial components proved to be difficult, despite the large head size, they were analysed mainly in situ via micro-computed tomography. Our results confirm previous observations of large differences in the tentorial construction in the giant pill-millipedes compared to chilognathan diplopods. The tentorium of Sphaerotheriida consists of a curved, plate-like epipharyngeal bar with distal projections, an elongate and thin hypopharyngeal bar, and a plate-like triangular posterior process; a transverse bar is absent. Only seven muscles attach at the tentorium in giant pill-millipedes, including two antennal muscles and two muscles of the gnathochilarium. Within the order Sphaerotheriida, the composition of the tentorium and its muscular equipment seems to be conserved, except for some variability in the shape of the epipharyngeal bar. As the transverse bar has been considered essential for the mobility of the tentorium in myriapods, its absence in Sphaerotheriida may indicate that their tentorium is not capable of performing a swing. Loss of tentorial mobility may also pertain to the order Glomerida Brandt, 1833, inferred here from the absence of a posterior process. An apparently immobile tentorium in Glomerida and Sphaerotheriida can straightforwardly be correlated with transformations of the head related to their ability of volvation. The different transformations of the tentorium, here hypothesised to cause immobility, may support current assumptions that the ability of volvation evolved convergently in Glomerida and Sphaerotheriida. This conclusion, however, still requires more detailed studies of the head

Full Text Available Danqi pill (DQP is a widely prescribed traditional Chinese medicine (TCM in the treatment of cardiovascular diseases. The objective of this study is to systematically characterize altered gene expression pattern induced by myocardial ischemia (MI in a rat model and to investigate the effects of DQP on global gene expression. Global mRNA expression was measured. Differentially expressed genes among the sham group, model group, and DQP group were analyzed. The gene ontology enrichment analysis and pathway analysis of differentially expressed genes were carried out. We quantified 10,813 genes. Compared with the sham group, expressions of 339 genes were upregulated and 177 genes were downregulated in the model group. The upregulated genes were enriched in extracellular matrix organization, response to wounding, and defense response pathways. Downregulated genes were enriched in fatty acid metabolism, pyruvate metabolism, PPAR signaling pathways, and so forth. This indicated that energy metabolic disorders occurred in rats with MI. In the DQP group, expressions of genes in the altered pathways were regulated back towards normal levels. DQP reversed expression of 313 of the 516 differentially expressed genes in the model group. This study provides insight into the multitarget mechanism of TCM in the treatment of complex diseases.

Purpose: To investigate phosphoinositide kinase-3 (PI3K) activation in relation to human papillomavirus (HPV) status in head and neck squamous cell carcinoma (HNSCC). Methods and Materials: Gene expression microarray data were analyzed to determine differentially expressed genes between HPV(+) and HPV(-) HNSCC. PIK3CA gene expression was confirmed by quantitative reverse transcriptase-polymerase chain reaction in seven HPV(+) and seven HPV(-) primary HNSCCs. PIK3CA mutation status in three HPV(+) and nine HPV(-) cell lines was determined by polymerase chain reaction amplification of hot spot exons (1, 9, 20) followed by direct sequencing. Results: PIK3CA was overexpressed in HPV(+)-associated HNSCC compared with the expression in HPV(-) HNSCC. Activation of PIK3CA by mutation was found in 1 of the 12 tested HNSCC cell lines. Conclusion: Activation of PI3K by mutation of PIK3CA is rare in HNSCC cell lines and was not found in three HPV(+) cell lines. One mechanism by which HPV-associated HNSCC might activate PI3K is increased expression of PIK3CA

A soft x-ray free electron laser (FEL) using a two-beam elliptical pill-box wake-field cavity

Stimulated bremsstrahlung in an undulating electric field in the lasing beam direction (electric wiggler) was shown to be possible from the quantum- mechanical viewpoint. Herein, this possibility is scrutinized from the viewpoint of classical electrodynamics. It is found that if stimulated bremsstrahlung in a transverse undulating magnetic field (magnetic wiggler) occurs, stimulated bremsstrahlung in the electric wiggler must also occur. We further show that a free electron laser (FEL) using a magnetic wiggler to provide a catalyzer field for stimulated bremsstrahlung cannot serve as a practical FEL operating in the soft x-ray region from both theoretical and experimental viewpoints. On the other hand, the authors demonstrate that the FEL using a traveling wake field in a two-beam elliptical pill-box cavity is well suited as a source of coherent radiation in the soft x-ray region

We quantified the effects of Florida's prescription drug monitoring program and pill mill law on high-risk patients. We used QuintilesIMS LRx Lifelink data to identify patients receiving prescription opioids in Florida (intervention state, N: 1.13 million) and Georgia (control state, N: 0.54 million). The preintervention, intervention, and postintervention periods were July 2010 to June 2011, July 2011 to September 2011, and October 2011 to September 2012. We identified 3 types of high-risk patients: (1) concomitant users: patients with concomitant use of benzodiazepines and opioids; (2) chronic users: long-term, high-dose, opioid users; and (3) opioid shoppers: patients receiving opioids from multiple sources. We compared changes in opioid prescriptions between Florida and Georgia before and after policy implementation among high-risk/low-risk patients. Our monthly measures included (1) average morphine milligram equivalent per transaction, (2) total opioid volume across all prescriptions, (3) average days supplied per transaction, and (4) total number of opioid prescriptions dispensed. Among opioid-receiving individuals in Florida, 6.62% were concomitant users, 1.96% were chronic users, and 0.46% were opioid shoppers. Following policy implementation, Florida's high-risk patients experienced relative reductions in morphine milligram equivalent (opioid shoppers: -1.08 mg/month, 95% confidence interval [CI] -1.62 to -0.54), total opioid volume (chronic users: -4.58 kg/month, CI -5.41 to -3.76), and number of dispensed opioid prescriptions (concomitant users: -640 prescriptions/month, CI -950 to -340). Low-risk patients generally did not experience statistically significantly relative reductions. Compared with Georgia, Florida's prescription drug monitoring program and pill mill law were associated with large relative reductions in prescription opioid utilization among high-risk patients.

Emergency contraceptive pills (ECP) were recently made available over the counter in Bhutan. We evaluated knowledge, attitudes, and practices concerning ECP in 2 populations at risk for HIV and STI (sexually transmitted infections): entertainment women (drayang) and male truck drivers and helpers (truckers). Of 179 drayang and 437 truckers intercepted at venues, 73.7 and 21.1%, respectively, had heard of ECP; 47.0% of drayang had used them. Their concerns about ECP use included harm to the body, impact on future pregnancy, side effects, and HIV/STI risk. Education programs are needed in Bhutan to increase awareness of ECP for unplanned pregnancy and condoms to prevent HIV and STI.

Full Text Available Background: Cardiovascular diseases have various etiologies. Previous studies have come to contradictory results regarding the effects of Oral Contraceptive Pills (OCPs on the risk of myocardial infarction, angina pectoris, and venous thrombosis. Thus, further investigation is required in this area. Objectives: This study aimed to determine the relationship between cardiovascular diseases and some risk factors in the women with a history of contraceptive pills consumption. Patients and Methods: The present case-control study was conducted on 317 women with cardiovascular diseases (myocardial infarction, angina pectoris, and deep venous thrombosis selected through simple purposive sampling from CCU, ICU, post-ICU, and neurology departments of Nemazee, Faghihi, and Al-Zahra heart hospitals. Also, 371 controls were selected among 20 – 60 year-old women without cardiac diseases. The data were collected through questionnaires, interviewing the patients and their first-degree relatives, and the patients’ medical records. The main variables studied in both groups included the history of OCPs consumption, weight gain, blood sugar level, and hypertension. Then, the data were analyzed using chi-square test, correlation coefficient, and odds ratio. Besides, P < 0.05 was considered to be statistically significant. Results: The mean age of the study population was 49.2 ± 13.4 years. Besides, 10.6%, 4%, and 2.7% of the women had used OCPs for 6 - 10, 11 - 15, and more than 16 years, respectively. There were no significant differences between the two groups in terms of history of using OCPs (47.3% vs. 51.5%, P = 0.8. In addition, no significant relationship was observed between consumption of OCPs and incidence of myocardial infarction (P = 0.202, angina pectoris (P = 0.260, and thrombosis (P = 0.389. However, a significant difference was found between the two groups regarding the frequency of hyperlipidemia, hyperglycemia, and hypertension (P < 0

Project Octo-Pills - A practice model engaging community pharmacists in the care of patients from a tertiary hospital.

2017-10-13

Even while pharmacy practice evolves to a more patient-centric mode of practice, local hospitals, due to high patient load as well as space and resource constraints, find it challenging to conduct thorough medication review and physical medication reconciliation for all patients. In light of this, optimizing the local current healthcare system to involve community pharmacists in the care of patients from public hospitals could potentially better cater to the healthcare needs of the older population. Due to easy accessibility, community pharmacies are often the first point of contact in the healthcare system. Project Octo-Pills aims to engage community pharmacists in the collaborative care of patients from a tertiary hospital, providing patients with quality medication reconciliation and review services from a more convenient location within their neighborhood. This paper describes the model for this pilot initiative. Copyright © 2017 Elsevier Inc. All rights reserved.

2015-07-01

Polycystic ovarian syndrome (PCOS) is characterized by irregular menses, elevated androgens, and insulin resistance. Little information is published about the treatment of adolescent PCOS. The aim of this study was to evaluate metformin versus oral contraceptive pills (OCP) in treating adolescent PCOS. Twenty-two girls were randomized to either treatment for 6 months. The outcomes variables included body mass index (BMI) and free testosterone (FT). BMI decreased in all patients (metformin p=0.004, OCP p=0.045). FT decreased significantly only with OCP. Insulin resistance measures decreased in all patients but did not reach significance. The only significant difference in any of the variables between the two groups was number of menses. BMI and FT remained less than baseline for 3 months off treatment. Metformin and OCP have a positive effect on BMI, which persists after treatment is discontinued. FT decreased with both treatments, but only reached significance with OCP.

Several lines of research indicate that statins can lower blood pressure (BP) independently of their lipid-lowering effects when used as monotherapy and in combination with antihypertensive agents. This short-term, open-label study examined whether statin therapy had a synergistic effect on the BP-lowering efficacy of perindopril/amlodipine in a subgroup of patients in the PERSPECTIVA study with concomitant hypertension and hypercholesterolemia, with or without statin at baseline. The PERSPECTIVA study recruited 732 adults with untreated or uncontrolled hypertension. This subgroup analysis of PERSPECTIVA included 587 patients with concomitant hypertension and hypercholesterolemia (mean age 56.7 years) of whom 226 were receiving a statin at baseline (statin [+] group) and 361 were not (statin [-] group). All patients received treatment with single-pill combination perindopril/amlodipine at a dose of 5/5, 10/5 or 10/10 mg/day. The study duration was 60 days with follow-up visits for BP monitoring at 7, 15, 30 and 60 days. At day 60, BP control (statin [+] vs statin [-] group: 73 vs 64% respectively (+14%, P statin [+] group, the single-pill perindopril/amlodipine combination significantly reduced BP in patients previously untreated (n = 18), or treated with monotherapy (n = 97), dual therapy (n = 93), or triple therapy (n = 18): -38.8/-20.0, -39.1/-20.1, -38.0/-19.4, -39.9/-18.3 mmHg respectively (P statin [+] group (0.9%) vs the statin [-] group (2.5%). BP control rates in patients with uncontrolled hypertension and concomitant hypercholesterolemia are significantly improved with a treatment regimen that combines perindopril/amlodipine with statin therapy, regardless of previous antihypertensive therapy. This subanalysis of the PERSPECTIVA study supports the synergistic BP-lowering effect of statins and perindopril/amlodipine.

Genome-wide analysis of the phosphoinositide kinome from two ciliates reveals novel evolutionary links for phosphoinositide kinases in eukaryotic cells.

Directory of Open Access Journals (Sweden)

George Leondaritis

Full Text Available BACKGROUND: The complexity of phosphoinositide signaling in higher eukaryotes is partly due to expansion of specific families and types of phosphoinositide kinases (PIKs that can generate all phosphoinositides via multiple routes. This is particularly evident in the PI3Ks and PIPKs, and it is considered an evolutionary trait associated with metazoan diversification. Yet, there are limited comprehensive studies on the PIK repertoire of free living unicellular organisms. METHODOLOGY/PRINCIPAL FINDINGS: We undertook a genome-wide analysis of putative PIK genes in two free living ciliated cells, Tetrahymena and Paramecium. The Tetrahymena thermophila and Paramecium tetraurelia genomes were probed with representative kinases from all families and types. Putative homologs were verified by EST, microarray and deep RNA sequencing database searches and further characterized for domain structure, catalytic efficiency, expression patterns and phylogenetic relationships. In total, we identified and characterized 22 genes in the Tetrahymena thermophila genome and 62 highly homologues genes in Paramecium tetraurelia suggesting a tight evolutionary conservation in the ciliate lineage. Comparison to the kinome of fungi reveals a significant expansion of PIK genes in ciliates. CONCLUSIONS/SIGNIFICANCE: Our study highlights four important aspects concerning ciliate and other unicellular PIKs. First, ciliate-specific expansion of PI4KIII-like genes. Second, presence of class I PI3Ks which, at least in Tetrahymena, are associated with a metazoan-type machinery for PIP3 signaling. Third, expansion of divergent PIPK enzymes such as the recently described type IV transmembrane PIPKs. Fourth, presence of possible type II PIPKs and presumably inactive PIKs (hence, pseudo-PIKs not previously described. Taken together, our results provide a solid framework for future investigation of the roles of PIKs in ciliates and indicate that novel functions and novel regulatory

To determine the awareness of, access to, and knowledge of the proper use of emergency contraception pills (ECPs) among uninsured adolescents. Anonymous surveys were used to assess awareness of, knowledge of, and access to ECPs. From 2010 to 2012 at mobile primary care clinic in the San Francisco Bay Area. Patients were uninsured adolescents aged 13 to 25; 40% of the participants were currently or had been homeless in the past year. Ethnicity was 50% Asian, 22% Hispanic, 17% Pacific Islanders, 5.5% white, and 5.5% other/mixed ethnicity. Post survey completion, patients received one-on-one 15-minute dedicated ECP education. Awareness of, knowledge of, and access to ECPs. Of the study population of 439, 30% of the participants were 13-16 years old and 70% were 17-25 years old (mean age 17.8 years); 66% were women. Young women (86%) reported higher rates of "hearing about emergency contraception" than did young men (70%) (P < .0001). Many incorrectly identified or were uncertain if ECPs were an abortion pill (40%) or could be used as regular birth control (40%) or to prevent sexually transmitted infections (19%). Only 40% of women and 43% of men aged 17 and older correctly answered that they could obtain EC over the counter; 72% did not know that males could receive EC for use by their partner; 12% incorrectly selected that infertility was a side effect; 44% were under the false impression that EC had to be taken within 1 day of unprotected sex. Uninsured adolescents have high rates of ECP awareness but low ECP knowledge. These adolescents need more ECP education to alleviate misconceptions and increase practical knowledge, specifically, education about male access, side effects, over-the-counter availability for young men and women, and the 120-hour window of use.

Diet pills and the cataract outbreak of 1935: reflections on the evolution of consumer protection legislation.

Science.gov (United States)

Margo, Curtis E; Harman, Lynn E

2014-01-01

An outbreak of cataracts in 1935 caused by dinitrophenol (DNP), the active ingredient of popular diet pills, highlighted the inability of the U.S. Food and Drug Administration (FDA) to prevent harmful drugs from entering the marketplace. Just two years earlier, the FDA used horrific images of ocular surface injury caused by cosmetics at the World's Fair in Chicago to garner public support for legislative reform. The FDA had to walk a fine line between a public awareness campaign and lobbying Congress while lawmakers debated the need for consumer protection. The cataract outbreak of 1935 was conspicuous in the medical literature during the height of New Deal legislation, but questions persist as to how much it affected passage of the proposed Food, Drug, and Cosmetic Act (of 1938). The legislation languished in committee for years. The cataract outbreak probably had little impact on the eventual outcome, but medical opinion concerning the safety of DNP may have contributed to the voluntary withdrawal of the diet drug from the market. We review the DNP cataract outbreak and examine it in context of the challenges facing regulatory reform at that time. Copyright © 2014 Elsevier Inc. All rights reserved.

Modernizing the 5G 100/8 piston compressor by means of directly streaming valves

Deals with 5G 100/8 air compressors which, despite long service and lack of spare parts, are still widely used in Bulgarian underground coal mines. K-4-10 ring-type valves are in particularly short supply; maintenance engineers have been forced to modify the compresors. Initially, Bulgarian KP-3.1 valves with direct air streaming replaced the K-4-10; these were later replaced by PIK-220 and PIK-220A valves. Tests on overhauled compressors have shown that replacing the KP-3.1 with the PIK-220 or PIK-220A can result in a saving of up to 100,000 kWh of electricity per compressor. Details of reconstruction and testing of piston compressors are included. 10 refs.

Full Text Available Sheila Krishnan, Jessica KileyDepartment of Obstetrics and Gynecology, Northwestern University, Chicago, Illinois, USAAbstract: Extended-cycle oral contraceptives (OCs are increasing in popularity in the United States. A new extended-cycle OC that contains the lowest doses of ethinyl estradiol (EE and levonorgestrel (LNG + continuous EE throughout the cycle is now available. It provides 84 days of a low-dose, combined active pill containing levonorgestrel 100 µg and ethinyl estradiol 20 µg. Instead of 7 days of placebo following the active pills, the regimen delivers 7 days of ethinyl estradiol 10 µg. Existing studies reveal a similar efficacy and adverse effect profile compared with other extended-regimen OCs. Specifically, the unscheduled bleeding profile is similar to other extended-cycle OCs and improves with the increase in the duration of use. Although lower daily doses of hormonal exposure have potential benefit, to our knowledge, there are no published studies indicating that this specific regimen offers a lower incidence of hormone-related side effects or adverse events. In summary, this new extended-cycle OC provides patients a low-dose, extended-regimen OC option without sacrificing efficacy or tolerability.Keywords: continuous regimen, ethinyl estradiol, extended cycle, oral contraceptive

Solid papillary carcinoma with reverse polarity (SPCRP) is a rare breast cancer subtype with an obscure etiology. In this study, we sought to describe its unique histopathologic features and to identify the genetic alterations that underpin SPCRP using massively parallel whole-exome and targeted sequencing. The morphologic and immunohistochemical features of SPCRP support the invasive nature of this subtype. Ten of 13 (77%) SPCRPs harbored hotspot mutations at R172 of the isocitrate dehydrogenase IDH2, of which 8 of 10 displayed concurrent pathogenic mutations affecting PIK3CA or PIK3R1. One of the IDH2 wild-type SPCRPs harbored a TET2 Q548* truncating mutation coupled with a PIK3CA H1047R mutation. Functional studies demonstrated that IDH2 and PIK3CA hotspot mutations are likely drivers of SPCRP, resulting in its reversed nuclear polarization phenotype. Our results offer a molecular definition of SPCRP as a distinct breast cancer subtype. Concurrent IDH2 and PIK3CA mutations may help diagnose SPCRP and possibly direct effective treatment.

How the pill became a lifestyle drug: the pharmaceutical industry and birth control in the United States since 1960.

Marketing decisions, rather than scientific innovations, have guided the development and positioning of contraceptive products in recent years. I review the stalled progress in contraceptive development in the decades following the advent of the Pill in 1960 and then examine the fine-tuning of the market for oral contraceptives in the 1990s and 2000s. Although birth control has been pitched in the United States as an individual solution, rather than a public health strategy, the purpose of oral contraceptives was understood by manufacturers, physicians, and consumers to be the prevention of pregnancy, a basic health care need for women. Since 1990, the content of that message has changed, reflecting a shift in the drug industry's view of the contraception business. Two factors contributed to bring about this change: first, the industry's move away from research and development in birth control and second, the growth of the class of medications known as lifestyle drugs.

Multiple metabolic alterations exist in mutant PI3K cancers, but only glucose is essential as a nutrient source.

Directory of Open Access Journals (Sweden)

Rebecca Foster

Full Text Available Targeting tumour metabolism is becoming a major new area of pharmaceutical endeavour. Consequently, a systematic search to define whether there are specific energy source dependencies in tumours, and how these might be dictated by upstream driving genetic mutations, is required. The PI3K-AKT-mTOR signalling pathway has a seminal role in regulating diverse cellular processes including cell proliferation and survival, but has also been associated with metabolic dysregulation. In this study, we sought to define how mutations within PI3KCA may affect the metabolic dependency of a cancer cell, using precisely engineered isogenic cell lines. Studies revealed gene expression signatures in PIK3CA mutant cells indicative of a consistent up-regulation of glycolysis. Interestingly, the genes up- and down-regulated varied between isogenic models suggesting that the primary node of regulation is not the same between models. Additional gene expression changes were also observed, suggesting that metabolic pathways other than glycolysis, such as glutaminolysis, were also affected. Nutrient dependency studies revealed that growth of PIK3CA mutant cells is highly dependent on glucose, whereas glutamine dependency is independent of PIK3CA status. In addition, the glucose dependency exhibited by PIK3CA mutant cells could not be overridden by supplementation with other nutrients. This specific dependence on glucose for growth was further illustrated by studies evaluating the effects of targeted disruption of the glycolytic pathway using siRNA and was also found to be present across a wider panel of cancer cell lines harbouring endogenous PIK3CA mutations. In conclusion, we have found that PIK3CA mutations lead to a shift towards a highly glycolytic phenotype, and that despite suggestions that cancer cells are adept at utilising alternative nutrient sources, PIK3CA mutant cells are not able to compensate for glucose withdrawal. Understanding the metabolic

Conventional treatment for locally advanced rectal cancer usually combines neoadjuvant radiochemotherapy and surgery. Until recently, there have been limited predictive factors (clinical or biological) for rectal tumor response to conventional treatment. KRAS, BRAF and PIK3CA mutations are commonly found in colon cancers. In this study, we aimed to determine the mutation frequencies of KRAS, BRAF and PIK3CA and to establish whether such mutations may be used as prognostic and/or predictive factors in rectal cancer patients. We retrospectively reviewed the clinical and biological data of 98 consecutive operated patients between May 2006 and September 2009. We focused in patients who received surgery in our center after radiochemotherapy and in which tumor samples were available. In the 98 patients with a rectal cancer, the median follow-up time was 28.3 months (4–74). Eight out of ninety-eight patients experienced a local recurrence (8%) and 17/98 developed distant metastasis (17%). KRAS, BRAF and PIK3CA were identified respectively in 23 (23.5%), 2 (2%) and 4 (4%) patients. As described in previous studies, mutations in KRAS and BRAF were mutually exclusive. No patient with local recurrence exhibited KRAS or PIK3CA mutation and one harbored BRAF mutation (12.5%). Of the seventeen patients with distant metastasis (17%), 5 were presenting KRAS mutation (29%), one BRAF (5%) and one PIK3CA mutation (5%). No relationship was seen between PIK3CA, KRAS or BRAF mutation and local or distant recurrences. The frequencies of KRAS, BRAF and PIK3CA mutations in our study were lower than the average frequencies reported in colorectal cancers and no significant correlation was found between local/distant recurrences and KRAS, BRAF or PIK3CA mutations. Future studies with greater number of patients, longer follow-up time and greater power to predict associations are necessary to fully understand this relationship

Zhengtian pills (ZTPs) are traditional Chinese medicine (TCM) which have been commonly used to treat headaches. Volatile components of ZTPs extracted by ethyl acetate with an ultrasonic method were analyzed by gas chromatography mass spectrometry (GC-MS). Twenty-two components were identified, accounting for 78.884% of the total components of volatile oil. The three main volatile components including protocatechuic acid, ferulic acid, and ligustilide were simultaneously determined using ultra-high performance liquid chromatography coupled with diode array detection (UHPLC-DAD). Baseline separation was achieved on an XB-C18 column with linear gradient elution of methanol-0.2% acetic acid aqueous solution. The UHPLC-DAD method provided good linearity (R (2) ≥ 0.9992), precision (RSD components, protocatechuic acid, ferulic acid, and ligustilide, in 13 batches of ZTPs, which is suitable for discrimination and quality assessment of ZTPs.

Jia-Yuan-Qing pill (JYQP) composed of Porcellio laevis Latreille, Corydalis Rhizoma and Radix Cynanchi Paniculati at a ratio of 9:7:7 has been found to be an effective analgesic agent. The present study aimed to evaluate the safety, addictive potential and anti-cancer pain activity of JYQP in a rat model. During the 6-month chronic toxicity test, no significant changes in general behavior, defecation, postural abnormalities, dietary or water intake or blood biochemical parameters were observed in male and female rats. Although a high dose of JYQP (5 g/kg) caused swelling of the liver, spleen and kidney in male and female rats, no pathological changes were observed in all organs examined via hematoxylin and eosin staining. The analgesic effect of JYQP on bone cancer pain was successfully confirmed in a rat model of Walker 256 cell-induced bone cancer. In contrast to morphine, in a physical dependence test, JYQP produced no withdrawal symptoms following chronic administration. The data from this study provide experimental evidence supporting the clinical use of JYQP as an effective, safe and non-addictive agent for the treatment of bone cancer pain.

Full Text Available Coronary heart disease (CHD is one of the highest mortality diseases in the world. Traditional Chinese medicine compound Danshen dripping pills (CDDPs have currently made a great achievement in treating CHD. However, the therapeutic mechanism of CDDP is often poorly interpreted. In this study, a GC-MS-based metabonomic study was conducted to assess the holistic efficacy of CDDP for myocardial infarction in male Sprague-Dawley rats, which were divided into the control group, the sham group, the model group, the control + CDDP group, and the model + CDDP, with CDDP at a dose of 107 mg/kg·d (equal to 1.8 mL/kg·d. The metabonomic findings demonstrated great differences of metabolic pattern among sham, model, and the model + CDDP in the orthogonal partial least squares discriminant analysis (OPLS-DA models, which coordinated well with the assessment of plasma biochemistry and histopathological assay. Differentially expressed metabolites suggested that energy metabolism, glycolysis, and lipid metabolism might be disrupted by myocardial infarction. Both the potential metabolic biomarkers and the biochemical histopathological indices were regulated effectively by CDDP.

Evidence for $\\pi K$ -atoms with DIRAC-II

CERN Document Server

Allkofer, Yves

2008-01-01

DIRAC-II is a fixed-target experiment at the CERN Proton Synchroton (PS) which has been designed to search for piK atoms, a bound state of a pi±K± pair, and measure their lifetime. These atoms are observed through an excess of low energetic piK pairs over the background, detected in the two spectrometer arms. This excess comes from the ionization of piK atoms in the target and can be related to their mean life. The piK S-wave scattering length combination |a1/2 - a3/2| (for isospin 1/2 and 3/2) can be related to the latter. The aim of the upgraded DIRAC-II experiment is a measurement of the scattering length combination |a1/2 - a3/2| with a precision of 5%. piK atoms have not been observed so far. The original DIRAC experiment was designed to measure the scattering lengths of pipi atoms. So far, close to 15 000 atoms have been detected, leading to a precision on |a0 - a2| which is better than 10%. In chiral perturbation theories (ChPT) the pipi scattering lengths have been calculated with 2% precision a...

This study aims to determine whether emergency contraceptive pills (ECPs) are less safe and effective for women with obesity compared with those without obesity. We searched PubMed for articles through November 2015 regarding the safety and effectiveness of ECPs [ulipristal acetate (UPA), levonorgestrel (LNG) and combined estrogen and progestin] among obese users. We assessed study quality using the United States Preventive Services Task Force evidence grading system. We identified four pooled secondary analyses (quality: poor to fair), two of which examined UPA and three examined LNG formulations. Three analyses pooled overlapping data from a total of three primary studies and demonstrated significant associations between obesity and risk of pregnancy after ECP use. One analysis reported a 4-fold increased risk of pregnancy among women with obesity (BMI≥30kg/m 2 ) compared with women within normal/underweight categories (BMIcontraception; at weights less than 75 kg, the rate of pregnancy was less than 2%. Two analyses examining UPA suggested an approximate 2-fold increased risk of pregnancy among women with obesity compared with either normal/underweight women or nonobese (BMIemergency contraception options in order for them to understand their options, to receive advanced supplies of emergency contraception as needed and to understand how to access an emergency copper intrauterine device if desired.

Yueju Pill Rapidly Induces Antidepressant-Like Effects and Acutely Enhances BDNF Expression in Mouse Brain

Directory of Open Access Journals (Sweden)

Wenda Xue

2013-01-01

Full Text Available The traditional antidepressants have a major disadvantage in delayed onset of efficacy, and the emerging fast-acting antidepressant ketamine has adverse behavioral and neurotoxic effects. Yueju pill, an herb medicine formulated eight hundred years ago by Doctor Zhu Danxi, has been popularly prescribed in China for alleviation of depression-like symptoms. Although several clinical outcome studies reported the relative short onset of antidepressant effects of Yueju, this has not been scientifically investigated. We, therefore, examined the rapid antidepressant effect of Yueju in mice and tested the underlying molecular mechanisms. We found that acute administration of ethanol extract of Yueju rapidly attenuated depressive-like symptoms in learned helpless paradigm, and the antidepressant-like effects were sustained for at least 24 hours in tail suspension test in ICR mice. Additionally, Yueju, like ketamine, rapidly increased the expression of brain-derived neurotrophic factor (BDNF in the hippocampus, whereas the BDNF mRNA expression remained unaltered. Yueju rapidly reduced the phosphorylation of eukaryotic elongation factor 2 (eEF2, leading to desuppression of BDNF synthesis. Unlike ketamine, both the BDNF expression and eEF2 phosphorylation were revered at 24 hours after Yueju administration. This study is the first to demonstrate the rapid antidepressant effects of an herb medicine, offering an opportunity to improve therapy of depression.

The purpose of this research is to investigate the phenomenology of learning - people"s attitudes toward their learning experiences that have inherent worth in themselves (i.e., ontological learning) or have value outside of the learning itself (i.e., instrumental learning). In order to explore this topic, 58 participants from the U.S., Russia, and Brazil were interviewed with a central question derived from the science fiction writer Isaac Asimov's short story "Profession": whether participants would take a "Magic Learning Pill" (MLP) to avoid the process of learning, and instead magically acquire the knowledge. The MLP would guarantee the immediate learning by skipping the process of learning while achieving the same effect of gaining skills and knowledge. Almost all participants could think of some learning experiences for which they would take MLP and others for which they would not. Many participants would not take MLP for ontological learning, which is learning experiences that have inherent value for the people, while they would take MLP for instrumental learning, which is learning that mainly serves some other non-educational purposes. The main finding suggests that both instrumental and ontological types of learning are recognized by a wide range of people from diverse cultures as present and valued in their lives. This is especially significant in light of the overwhelmingly instrumental tone of public discourse about education. In the context of formal education, ontological learning was mentioned 35 times (28.0%) while instrumental learning was mentioned 74 times (60.2%). Although ontological learning was often mentioned as taking place outside of school, incorporating pedagogy supporting ontological learning at school deserves consideration.

To evaluate and compare the effectiveness of the combined regimen (consisting of condoms and emergency contraception pills (ECP)) and using condoms only for the purpose of preventing pregnancy. One-thousand-five-hundred-and-sixty-two (1,562) couples as volunteers enrolled at nine centers in Shanghai. Eight-hundred-and-twelve (812) were randomized to use male condoms and ECP (i.e., Levonorgestrel) as a back-up to condoms (the intervention group) and 750 to use male condoms only(the control group), according to their working unit. Participants were visited at admission and at the end of 1, 3, 6, 9, and 12 months. The cumulative life table rates were calculated for pregnancy and other reasons for discontinuation. The gross cumulative life table rates showed that the cumulative discontinuation rates for all reasons during the year of follow-up in the condoms plus emergency contraception group and the condoms only group were 7.76 ± 0.94 and 6.61 ± 0.91, respectively, per 100 women (χ2 = 0.41, p = 0.5227). The cumulative gross pregnancy rate of the condoms plus emergency contraception group and the condoms only group were 2.17 ± 0.52 and 1.25 ± 0.41, respectively, per 100 women (χ2 = 1.93, p = 0.1645). The Pearl Index in the condoms plus emergency contraception group and the condoms only group were 2.21% and 1.26%, respectively. Male condoms remain a highly effective contraceptive method for a period of one year while consistently and correctly used. In addition, the lowest pregnancy rate followed from perfect use condom.

Full Text Available Nephrotoxicity is a serious adverse effect of cisplatin chemotherapy that limits its clinical application, to deal with which no effective management is available so far. The present study was to investigate the potential protective effect of QiShenYiQi Pills (QSYQ, a compound Chinese medicine, against cisplatin induced nephrotoxicity in mice. Pretreatment with QSYQ significantly attenuated the cisplatin induced increase in plasma urea and creatinine, along with the histological damage, such as tubular necrosis, protein cast, and desquamation of epithelial cells, improved the renal microcirculation disturbance as indicated by renal blood flow, microvascular flow velocity, and the number of adherent leukocytes. Additionally, QSYQ prevented mitochondrial dysfunction by preventing the cisplatin induced downregulation of mitochondrial complex activity and the expression of NDUFA10, ATP5D, and Sirt3. Meanwhile, the cisplatin-increased renal thiobarbituric acid-reactive substances, caspase9, cleaved-caspase9, and cleaved-caspase3 were all diminished by QSYQ pretreatment. In summary, the pretreatment with QSYQ remarkably ameliorated the cisplatin induced nephrotoxicity in mice, possibly via the regulation of mitochondrial function, oxidative stress, and apoptosis.

Yes-associated protein (YAP), the nuclear effector of Hippo signaling, regulates cellular growth and survival in multiple organs, including the heart, by interacting with TEA (transcriptional enhancer activator)-domain sequence-specific DNA-binding proteins. Recent studies showed that YAP stimulates cardiomyocyte proliferation and survival. However, the direct transcriptional targets through which YAP exerts its effects are poorly defined. To identify direct YAP targets that mediate its mitogenic and antiapoptotic effects in the heart. We identified direct YAP targets by combining differential gene expression analysis in YAP gain- and loss-of-function with genome-wide identification of YAP-bound loci using chromatin immunoprecipitation and high throughput sequencing. This screen identified Pik3cb, encoding p110β, a catalytic subunit of phosphoinositol-3-kinase, as a candidate YAP effector that promotes cardiomyocyte proliferation and survival. YAP and TEA-domain occupied a conserved enhancer within the first intron of Pik3cb, and this enhancer drove YAP-dependent reporter gene expression. Yap gain- and loss-of-function studies indicated that YAP is necessary and sufficient to activate the phosphoinositol-3-kinase-Akt pathway. Like Yap, Pik3cb gain-of-function stimulated cardiomyocyte proliferation, and Pik3cb knockdown dampened YAP mitogenic activity. Reciprocally, impaired heart function in Yap loss-of-function was significantly rescued by adeno-associated virus-mediated Pik3cb expression. Pik3cb is a crucial direct target of YAP, through which the YAP activates phosphoinositol-3-kinase-AKT pathway and regulates cardiomyocyte proliferation and survival. © 2014 American Heart Association, Inc.

Full Text Available Abstract Background Poor adherence to the oral contraceptive pill (OCP is reported as one of the main causes of unintended pregnancy in women that rely on this form of contraception. This study aims to estimate the associations between a range of well-established modifiable psychological factors and adherence to OCP. Method A cross-sectional survey of 130 female University students currently using OCP (Mean age: 20.46 SD: 3.01, range 17–36 was conducted. An OCP specific Medication Adherence Report Scale was used to assess non-adherence. Psychological predictor measures included necessity and concern beliefs about OCP, intentions, perceived behavioural control (pbc, anticipated regret and action and coping planning. Multiple linear regression was used to analyse the data. Results Fifty-two per cent of participants reported missing their OCP once or more per month and 14% twice or more per month. In bivariate analysis intentions (r = −0.25, perceived behavioural control (r= −0.66, anticipated regret (r=0.20, concerns about OCP (r =0.31, and action (r= −0.25 and coping (r= −0.28 planning were all significantly associated with adherence to OCP in the predicted direction. In a multivariate model almost half (48% of the variation in OCP adherence could be explained. The strongest and only statistically significant predictors in this model were perceived behavioural control (β=−0.62, p Conclusion The present data point to a number of key modifiable psychological determinants of OCP use. Future work will establish whether changing these variables results in better adherence to the OCP.

Zuo-Gui pills (ZGPs) and You-Gui pills (YGPs) are 2 traditional Chinese herbal formulas used for treating multiple sclerosis (MS) in the clinical setting and have been shown to have neuroprotective effects in experimental autoimmune encephalomyelitis (EAE), an animal model of MS. The aim of this study was to explore the mechanisms underlying the neuroprotective functions of ZGPs and YGPs. Female Lewis rats were randomly divided into normal control, EAE model, 2g/kg ZGP-treated EAE, 3g/kg YGP-treated EAE, and prednisone acetate-treated groups. EAE model was induced by subcutaneous injection of MBP68-86 antigen. The neurological function scores were estimated. Histological structures of the brains and spinal cords were observed, and myelinated and axons imaged. NogoA, Nogo receptor (NgR), and RhoA transcript and protein levels were measured by real-time quantitative RT-PCR and western blotting on postimmunization (PI) days 14 (acute stage) and 28 (remission stage). ZGPs and YGPs significantly reduced neurological functions scores and abrogated inflammatory infiltrates, demyelination, and axonal damage. Furthermore, treatment with ZGPs and YGPs inhibited NogoA, NgR, and RhoA mRNA and protein expression in rats at both the acute and remission stages. ZGPs exhibited stronger effects on NogoA and RhoA expressions, as well as neurological function, during the acute stage of EAE, while YGPs caused greater reductions in NogoA expression during the remission stage. Our findings suggested that ZGPs and YGPs exerted neuroprotective effects by downregulation of NogoA, NgR, and RhoA pathways, with differences in response times and targets observed between ZGPs and YGPs.

Full Text Available Retinal vascular occlusion is the most common cause of retinopathy leading to severe visual loss in all age groups. Central retinal vein occlusion (CRVO is usually seen in older age group and is often associated with systemic vascular diseases. Although the exact cause and effect relationship has not been proven, central retinal vein occlusion has been associated with various systemic pathological conditions, hence a direct review of systems toward the various systemic and local factors predisposing the central retinal vein occlusion is advocated. We describe the development of central retinal venous occlusion with associated cystoid macular edema (CME in two healthy infertile women who were recruited for in vitro fertilization cycle for infertility. Predisposing risk factors associated with central retinal vein occlusion are obesity, sedentary life style, smoking, and some systemic diseases such as hyperlipidemia, hypertension, associated autoimmune disorders e.g., antiphospholipid antibody syndrome, lupus, diabetes mellitus, cardiovascular disorders, bleeding or clotting disorders, vasculitis, closed-head trauma, alcohol consumption, primary open-angle glaucoma or angle-closure glaucoma.In our patients, they were ruled out afterdoing allpertaining investigations. The cases were managed with further avoidance of oral contraceptives and intra-vitreal injections of Bevacizumab (Avastin, an anti-vascular endothelial growth factor (anti-VEGF drug and Triamcinolone acetonide (a long acting synthetic steroid. Hence, even if no systemic diseases are detected. Physical examinations are recommended periodically for young women on oral contraceptive pills.

Full Text Available Purpose. This study was aimed to investigate the reproductive toxicity of Zishen Yutai Pill (ZYP on fertility and early embryonic development in rats. Methods. SD rats were randomly divided into 5 groups: vehicle control group (distilled water, i.g., positive control group (80 mg/kg of cyclophosphamide, i.p., and three ZYP-treated groups (3, 6, and 12 g/kg/d, i.e., 12x, 24x, and 48x clinical doses, i.g.. The high dose was set as the maximum gavage dosage. Results. Cyclophosphamide showed diverse hazards, such as decreased weight of male reproductive organs and sperm density (P<0.05. However, there were no obvious effects of ZYP on physical signs, animal behavior, and survival rate, as well as on weight and food intake during the premating and gestation periods. Importantly, there were no significant adverse effects of ZYP on indexes of copulation, fecundity and fertility indexes, weights and coefficients of male reproductive organs, epididymal sperm number and motility, estrous cycle, preimplantation loss rate, and implantation rate. Besides, the numbers of live and resorbed fetuses per litter were not significantly altered. Conclusions. ZYP had no reproductive toxicities on fertility and early embryonic development in rats at 48x equivalent clinical doses.

The phosphatidylinositol 3-kinases-AKT-mammalian target of rapamycin pathway (PI3K/AKT/mTOR) is central in colorectal tumors. Data on its role in hereditary cancers are, however, scarce and we therefore characterized mutations in PIK3CA and KRAS, and expression of PIK3CA, phosphorylated AKT...... and PTEN in 58 HNPCC-associated colorectal cancers. Derangements of at least one of the PI3K/AKT/mTOR components analyzed were found in 51/58 (88%) tumors. Mutations in PIK3CA and KRAS were identified in 14 and 31% of the tumors respectively. Overexpression of PIK3CA and phosphorylated AKT occurred in 59...... and 75% and were strongly associated (P = 0.005). Reduced/lost PTEN expression was found in 63% of the tumors. Though HNPCC-associated colorectal cancers show simple genetic profiles with few chromosomal alterations, we demonstrate frequent and repeated targeting of the PI3K/AKT/mTOR pathway, which...

A mutant crp allele that differentially activates the operons of the fuc regulon in Escherichia coli.

Science.gov (United States)

Zhu, Y; Lin, E C

1988-05-01

L-Fucose is used by Escherichia coli through an inducible pathway mediated by a fucP-encoded permease, a fucI-encoded isomerase, a fucK-encoded kinase, and a fucA-encoded aldolase. The adolase catalyzes the formation of dihydroxyacetone phosphate and L-lactaldehyde. Anaerobically, lactaldehyde is converted by a fucO-encoded oxidoreductase to L-1,2-propanediol, which is excreted. The fuc genes belong to a regulon comprising four linked operons: fucO, fucA, fucPIK, and fucR. The positive regulator encoded by fucR responds to fuculose 1-phosphate as the effector. Mutants serially selected for aerobic growth on propanediol became constitutive in fucO and fucA [fucO(Con) fucA(Con)], but noninducible in fucPIK [fucPIK(Non)]. An external suppressor mutation that restored growth on fucose caused constitutive expression of fucPIK. Results from this study indicate that this suppressor mutation occurred in crp, which encodes the cyclic AMP-binding (or receptor) protein. When the suppressor allele (crp-201) was transduced into wild-type strains, the recipient became fucose negative and fucose sensitive (with glycerol as the carbon and energy source) because of impaired expression of fucA. The fucPIK operon became hyperinducible. The growth rate on maltose was significantly reduced, but growth on L-rhamnose, D-galactose, L-arabinose, glycerol, or glycerol 3-phosphate was close to normal. Lysogenization of fuc+ crp-201 cells by a lambda bacteriophage bearing crp+ restored normal growth ability on fucose. In contrast, lysogenization of [fucO(Con)fucA(Con)fucPIK(Non)crp-201] cells by the same phage retarded their growth on fucose.

In the last decade, several epidemiological studies have shown the increased risk of venous thromboembolism associated with third- and fourth-generation oral contraceptives (C3Gs and C4Gs) versus older combined first- and second-generation oral contraceptives (C1Gs and C2Gs). In France, in December 2012, a lawsuit filed against the National Agency for the Safety of Medicines and Health Products (ANSM) by a patient who had experienced a stroke, possibly due to the use of a C3G, triggered a national 'pill crisis'. Consequently, a 'crisis cell' was set up and pre-existing health recommendations were reinforced. The main aim of this study was to evaluate, in real time, the impact of the French health authorities' recommendations and communications on French women's behaviour regarding contraception. Real-time monthly sales data reported during 2013 were compared with monthly sales data reported in 2012. Analyses were stratified according to the type of contraceptive and age. An index corresponding to the number of months of contraception sold was developed to facilitate comparison of the different contraceptives despite their distinct features and to assess the overall trend of contraception. After a 2-year analysis (2013 versus 2012), a significant 45 % decrease (p sales was observed, compared with a significant increase of 30 % (p sales. The sharp increase in C1G-2G sales focused specifically on C2Gs with an oestrogen concentration below 20 µg. Moreover, a large (47 %) increase was reported in sales of intrauterine devices (p sales into account, a slight decrease (1 %) in overall sales was identified. Thanks to an effective national communication plan, real-time monitoring of drug sales and favourable reactions from physicians and patients, French women changed their behaviour regarding contraception. However, this study was conducted over a short period following the crisis. A longitudinal analysis is required in order to assess any real long-term changes.

Full Text Available Molecular screening of major rice blast resistance genes was determined with molecular markers, which showed close-set linkage to 11 major rice blast resistance genes (Pi-d2, Pi-z, Piz-t, Pi-9, Pi-36, Pi-37, Pi5, Pi-b, Pik-p, Pik-h and Pi-ta2, in a collection of 32 accessions resistant to Magnaporthe oryzae. Out of the 32 accessions, the Pi-d2 and Pi-z appeared to be omnipresent and gave positive express. As the second dominant, Pi-b and Piz-t gene frequencies were 96.9% and 87.5%. And Pik-h and Pik-p gene frequencies were 43.8% and 28.1%, respectively. The molecular marker linkage to Pi-ta2 produced positive bands in eleven accessions, while the molecular marker linkage to Pi-36 and Pi-37 in only three and four accessions, respectively. The natural field evaluation analysis showed that 30 of the 32 accessions were resistant, one was moderately resistant and one was susceptible. Infection types were negatively correlated with the genotype scores of Pi-9, Pi5, Pi-b, Pi-ta2 and Pik-p, although the correlation coefficients were very little. These results are useful in identification and incorporation of functional resistance genes from these germplasms into elite cultivars through marker-assisted selection for improved blast resistance in China and worldwide.

During a severe accident in a nuclear power plant the release of radioactive iodine is possible. A precautionary measure to prevent man from the reception of radioactive iodine is an early and right taking of non-radioactive iodine pills. After the accident in Fukushima iodine tablets have been stored by authorities as an precautionary measures. In the case of an accident, a quick distribution should be possible. One question which arises are the costs bearers of such a storage. Are nuclear power plant operators responsible for such measures, carried out by the authorities?.

Full Text Available Objective: The objective of this study was to collect evidence with respect to perception and practice of unmarried women toward the use of emergency contraceptive pills (ECPs. Materials and Methods: Non-probability purposive sampling was used to select respondents. A total of 250 respondents were administered the tools for the study, of which 228 were considered for analysis. Results and Discussion: Descriptive statistics showed that nearly 87% of the respondents were aware of ECPs and there was a significant difference in the knowledge of ECP of the respondents by type of the institution they had studied. More than half of the (52% respondents admitted to have boyfriends of which 16% were sexually involved and were using some form of contraception. Nearly 84% of the respondents used ECP, which superseded the use of other contraceptives. It was further found that around two-third respondents were using ECP regularly. The reason that "ECP did not hinder pleasure" and that it was handy in case of "unplanned contact" were the most cited reasons for using ECP as a regular contraceptive. Conclusion: The fact that ECPs was preferred over condom and was used regularly shows that the respondents were at a risk of sexually transmitted infection/human immunodeficiency virus. Health-care providers could be the most authentic source of information for orienting young women toward the use of safe sexual practices.

Oral squamous cell carcinoma (OSCC) is one of the most common types of the head and neck cancer. Chemo resistance of OSCC has been identified as a substantial therapeutic hurdle. In this study, we analyzed the role of miR-203 in the OSCC and its effects on cisplatin-induced cell death in an OSCC cell line, Tca8113. There was a significant decrease of miR-203 expression in OSCC samples, compared with the adjacent normal, non-cancerous tissue. After 3 days cisplatin treatment, the survived Tca8113 cells had a lower expression of miR-203 than that in the untreated control group. In contrast, PIK3CA showed an inverse expression in cancer and cisplatin survived Tca8113 cells. Transfection of Tca8113 cells with miR-203 mimics greatly reduced PIK3CA expression and Akt activation. Furthermore, miR-203 repressed PIK3CA expression through targeting the 3′UTR. Restoration of miR-203 not only suppressed cell proliferation, but also sensitized cells to cisplatin induced cell apoptosis. This effect was absent in cells that were simultaneously treated with PIK3CA RNAi. In summary, these findings suggest miR-203 plays an important role in cisplatin resistance in OSCC, and furthermore delivery of miR-203 analogs may serve as an adjuvant therapy for OSCC. - Highlights: • Much lower miR-203 expression in cisplatin resistant Tca8113 cells is discovered. • Delivery of miR-203 can sensitize the Tca8113 cells to cisplatin induced cell death. • MiR-203 can downregulate PIK3CA through the 3′UTR. • The effects of miR-203 on cisplatin sensitivity is mainly through PIK3CA pathway.

Cancer such as hepatocellular carcinoma (HCC) is characterized by complex perturbations in multiple signaling pathways, including the phosphoinositide-3-kinase (PI3K/AKT) pathways. Herein we investigated the role of PI3K catalytic isoforms, particularly class II isoforms in HCC proliferation. Among the siRNAs tested against the eight known catalytic PI3K isoforms, specific ablation of class II PI3K alpha (PIK3C2{alpha}) was the most effective in impairing cell growth and this was accompanied by concomitant decrease in PIK3C2{alpha} mRNA and protein levels. Colony formation ability of cells deficient for PIK3C2{alpha} was markedly reduced and growth arrest was associated with increased caspase 3 levels. A small but significant difference in gene dosage and expression levels was detected between tumor and non-tumor tissues in a cohort of 19 HCC patients. Taken together, these data suggest for the first time that in addition to class I PI3Ks in cancer, class II PIK3C2{alpha} can modulate HCC cell growth.

Danqi Pill (DQP), which contains Chinese herbs Salvia miltiorrhiza Bunge and Panax notoginseng, is widely used in the treatment of myocardial ischemia (MI) in China. Its regulatory effects on MI-associated lipid metabolism disorders haven't been comprehensively studied so far. We aimed to systematically investigate the regulatory mechanism of DQP on myocardial ischemia-induced lipid metabolism disorders. Myocardial ischemia rat model was induced by left anterior descending coronary artery ligation. The rat models were divided into three groups: model group with administration of normal saline, study group with administration of DanQi aqueous solution (1.5 mg/kg) and positive-control group with administration of pravastatin aqueous solution (1.2 mg/kg). In addition, another sham-operated group was set as negative control. At 28 days after treatment, cardiac function and degree of lipid metabolism disorders in rats of different groups were measured. Plasma lipid disorders were induced by myocardial ischemia, with manifestation of up-regulation of triglyceride (TG), low density lipoprotein (LDL), Apolipoprotein B (Apo-B) and 3-hydroxy-3-methyl glutaryl coenzyme A reductase (HMGCR). DQP could down-regulate the levels of TG, LDL, Apo-B and HMGCR. The Lipid transport pathway, fatty acids transport protein (FATP) and Carnitine palmitoyltransferase I (CPTI) were down-regulated in model group. DQP could improve plasma lipid metabolism by up-regulating this lipid transport pathway. The transcription factors peroxisome proliferator-activated receptor α (PPARα) and retinoid X receptors (RXRs), which regulate lipid metabolism, were also up-regulated by DQP. Furthermore, DQP was able to improve heart function and up-regulate ejection fraction (EF) by increasing the cardiac diastolic volume. Our study reveals that DQP would be an ideal alternative drug for the treatment of dyslipidemia which is induced by myocardial ischemia.

This open-label randomized controlled trial was designed to compare the efficacy of acupuncture and combined oral contraceptive (COC) pill in treating moderate-to-severe primary dysmenorrhea. Fifty-two participants were randomly assigned to receive either acupuncture (n = 27) or COC (n = 25) for three menstrual cycles. Mefenamic acid was prescribed as a recue analgesic drug with both groups. The statistical approach used for efficacy and safety assessments was intention-to-treat analysis. By the end of the study, both treatments had resulted in significant improvement over baselines in all outcomes, that is, maximal dysmenorrhea pain scores, days suffering from dysmenorrhea, amount of rescue analgesic used, and quality of life assessed by SF-36 questionnaire. Over the three treatment cycles, COC caused greater reduction in maximal pain scores than acupuncture, while improvements in the remaining outcomes were comparable. Responders were defined as participants whose maximal dysmenorrhea pain scores decreased at least 33% below their baseline. Response rates following both interventions at the end of the study were not statistically different. Acupuncture commonly caused minimal local side effects but did not cause any hormone-related side effects as did COC. In conclusion, acupuncture is an alternative option for relieving dysmenorrhea, especially when COC is not a favorable choice. PMID:26346199

To explore the effects of Chinese medicine prescription Zuogui Pill (, ZGP) on monoamine neurotransmitters and sex hormones in climacteric rats with induced panic attacks. Forty-eight climacteric female rats were randomized into 6 groups with 8 rats in each group: the control group, the model group, the low-, medium- and high-dose ZGP groups and the alprazolam group. Rats in the low-, medium- and high-dose ZGP groups were administered 4.725, 9.45, or 18.9 g/kg ZGP by gastric perfusion, respectively. The alprazolam group was treated by gastric perfusion with 0.036 mg/kg alprazolam. The control and model groups were treated with distilled water. The animals were pretreated once daily for 8 consecutive weeks. The behaviors of rats in the open fifield test and the elevated T-maze (ETM) were observed after induced panic attack, and the levels of brain monoamine neurotransmitters and the plasma levels of sex hormones were measured. Compared with the control group, the mean ETM escape time and the levels of 5-hydroxytryptamine (5-HT) and noradrenalin (NE) of the model group were signifificantly reduced (P<0.05), Compared with the model group, the mean ETM escape time and the 5-HT and NE levels of all the ZGP groups increased signifificantly (P<0.05 or P<0.01). However, no signifificant difference was observed in the levels of sex hormones between the groups. Pretreatment with ZGP in climacteric rats may improve the behavior of panic attack, which may be related to increased 5-HT and NE in the brain.

To systematically review the impact of Yasmin (drospirenone pill) compares with other standard treatments for symptoms of Polycystic Ovary Syndrome (PCOS). The relevant studies of the randomized controlled trials in women with PCOS treated with drospirenone were retrieved and the systematic evaluation was conducted. Eighteen articles were included. Compared with drospirenone (DRSP) monotherapy, DRSP plus metformin was better in reducing body mass index (BMI), luteinizing hormone (LH) and low-density lipoprotein cholesterol (LDL-C). Compared with metformin, DRSP was better in modulating serum total testosterone (T), sex hormone-binding globulin (SHBG), follicle stimulating hormone (FSH) and free androgen index (FAI), while metformin was more effective in reducing BMI, total cholesterol (TC), LDL-C and Triglyceride (TG). DRSP was superior to cyproterone acetate (CPA) in reducing TC and homeostasis model assessment of insulin resistance (HOMA-IR). DRSP shows better effect in modulating LDL-C and high-density lipoprotein cholesterol (HDL-C) compared with desogestrel (DSG). The available data suggested that DRSP was effective in modulating hormones, insulin and lipid metabolism in women with PCOS. Compared with commonly used drugs for symptoms of PCOS as CPA and DSG, DRSP shows identical or better effect in improving symptoms and protect cardiovascular system. For the PCOS patients with IR, obesity or high LH/FSH ratio, DRSP combines with metformin maybe more effective than use DRSP alone. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Full Text Available Abstract Background KRAS mutations negatively affect outcome after treatment with cetuximab in metastatic colorectal cancer (mCRC patients. As only 20% of KRAS wild type (WT patients respond to cetuximab it is possible that other mutations, constitutively activating the EGFR pathway, are present in the non-responding KRAS WT patients. We retrospectively analyzed objective tumor response rate, (ORR progression-free (PFS and overall survival (OS with respect to the mutational status of KRAS, BRAF, PIK3CA and PTEN expression in mCRC patients treated with a cetuximab-based regimen. Methods 67 mCRC patients were enrolled onto the study. DNA was extracted from paraffin-embedded sections derived from primary or metastatic lesions. Exon 2 of KRAS and exon 15 of BRAF were analyzed by direct sequencing, PIK3CA was evaluated by pyrosequencing and PTEN expression by immunohistochemistry. Results BRAF and PIK3CA mutations were independently associated with worse PFS (p = 0.006 and p = 0.028, respectively and OS (p = 0.008 and p = 0.029, respectively. No differences in clinical outcome were found between patients who were positive or negative for PTEN expression. Conversely, patients negative for KRAS, BRAF and PIK3CA mutations were characterized by significantly better ORR, PFS and OS than patients with at least one of these mutations. Conclusions BRAF and PIK3CA mutations would seem to be independent predictors of anti-EGFR therapy effectiveness and could be taken into consideration during treatment decision making.

The treatment of iron-deficiency anemia with oral iron supplements can present side-effects on the GI tract mucosa including necrosis, ulceration, or ischemia. The particular endoscopic findings and the histopathological exam will establish the diagnosis of erosive gastritis with iron deposits in the gastric mucosa. We present the case of a 14-year-old female admitted in our clinic for upper digestive hemorrhage, nausea, melena, and abdominal pain. Her personal history revealed iron deficiency anemia receiving oral iron supplements for approximately 2 weeks. The laboratory tests at the moment of admission pointed out anemia, increased level of serum iron, increased liver transaminases, a decreased level of ferritin, but with normal levels of both total iron-binding capacity and transferrin. The eso-gastro-duodenoscopy revealed multiple brown deposits on the surface of the gastric mucosa and multiple hemorrhagic lesions, under the aspect of erosions all over the gastric mucosa, but more severe in the antral part, and the histopathological exam confirmed the presence of iron deposits at this level. Iron-pill induced gastritis is a rare, under-diagnosed entity that can be present even at pediatric ages with potential severe clinical impact.

The CHER-LOB randomized phase II study showed that the combination of lapatinib and trastuzumab plus chemotherapy increases the pathologic complete remission (pCR) rate compared with chemotherapy plus either trastuzumab or lapatinib. A biomarker program was prospectively planned to identify potential predictors of sensitivity to different treatments and to evaluate treatment effect on tumor biomarkers. Overall, 121 breast cancer patients positive for human epidermal growth factor 2 (HER2) were randomly assigned to neoadjuvant chemotherapy plus trastuzumab, lapatinib, or both trastuzumab and lapatinib. Pre- and post-treatment samples were centrally evaluated for HER2, p95-HER2, phosphorylated AKT (pAKT), phosphatase and tensin homolog, Ki67, apoptosis, and PIK3CA mutations. Fresh-frozen tissue samples were collected for genomic analyses. A mutation in PIK3CA exon 20 or 9 was documented in 20% of cases. Overall, the pCR rates were similar in PIK3CA wild-type and PIK3CA-mutated patients (33.3% vs. 22.7%; p = .323). For patients receiving trastuzumab plus lapatinib, the probability of pCR was higher in PIK3CA wild-type tumors (48.4% vs. 12.5%; p = .06). Ki67, pAKT, and apoptosis measured on the residual disease were significantly reduced from baseline. The degree of Ki67 inhibition was significantly higher in patients receiving the dual anti-HER2 blockade. The integrated analysis of gene expression and copy number data demonstrated that a 50-gene signature specifically predicted the lapatinib-induced pCR. PIK3CA mutations seem to identify patients who are less likely to benefit from dual anti-HER2 inhibition. p95-HER2 and markers of phosphoinositide 3-kinase pathway deregulation are not confirmed as markers of different sensitivity to trastuzumab or lapatinib. HER2 is currently the only validated marker to select breast cancer patients for anti-HER2 treatment; however, it is becoming evident that HER2-positive breast cancer is a heterogeneous disease. In addition, more

Merkel cell polyomavirus (MCPyV) integrates monoclonally into the genomes of approximately 80% of Merkel cell carcinomas (MCCs), affecting their clinicopathological features. The molecular mechanisms underlying MCC development after MCPyV infection remain unclear. We investigated the association of MCPyV infection with activation of the Akt/mammalian target of rapamycin (mTOR)/4E-binding protein 1 (4E-BP1) signaling pathway in MCCs to elucidate the role of these signal transductions and to identify molecular targets for treatment. We analyzed the molecular and pathological characteristics of 41 MCPyV-positive and 27 MCPyV-negative MCCs. Expression of mTOR, TSC1, and TSC2 messenger RNA was significantly higher in MCPyV-negative MCCs, and Akt (T308) phosphorylation also was significantly higher (92% vs 66%; P = .019), whereas 4E-BP1 (S65 and T70) phosphorylation was common in both MCC types (92%-100%). The expression rates of most other tested signals were high (60%-100%) and not significantly correlated with MCPyV large T antigen expression. PIK3CA mutations were observed more frequently in MCPyV-positive MCCs (6/36 [17%] vs 2/20 [10%]). These results suggest that protein expression (activation) of most Akt/mTOR/4E-BP1 pathway signals was not significantly different in MCPyV-positive and MCPyV-negative MCCs, although these 2 types may differ in tumorigenesis, and MCPyV-negative MCCs showed significantly more frequent p-Akt (T308) activation. Therefore, certain Akt/mTOR/4E-BP1 pathway signals could be novel therapeutic targets for MCC regardless of MCPyV infection status. Copyright © 2015 Elsevier Inc. All rights reserved.

Electron–Cyclotron Laser Using Free-Electron Two-Quantum Stark Radiation in a Strong Uniform Axial Magnetic Field and an Alternating Axial Electric Field in a Voltage-Supplied Pill-Box Cavity

2016-01-01

We consider the radiation from the beam electrons traveling in a strong uniform axial magnetic field and an axial alternating electric field of wavelength λ_w generated by a voltage-supplied pill-box cavity. The beam electrons emit genuine laser radiation that propagates only in the axial direction through free-electron two-quantum Stark radiation. We find that laser radiation takes place only at the expense of the axial kinetic energy when λ_w ≪ c/(ω_c/γ), where ω_c/γ is the relativistic electron–cyclotron frequency. We formulate the laser power based on quantum-wiggler electrodynamics, and envision a laser of length 10 m with estimated power 0.1 GW/(kA) in the 10"−"4 cm wavelength range. (paper)

A retrospective study. The aim of this study was to investigate the correlation between pelvic incidence (PI) and lumbar lordosis (LL) mismatch and knee flexion during standing in patients with lumbar degenerative diseases and to examine the effects of surgical correction of the PI-LL mismatch on knee flexion. Only several studies focused on knee flexion as a compensatory mechanism of the PI-LL mismatch. Little information is currently available on the effects of lumbar correction on knee flexion in patients with the PI-LL mismatch. A group of patients with lumbar degenerative diseases were divided into PI-LL match group (PI-LL ≤ 10°) and PI-LL mismatch group (PI-LL > 10°). A series of radiographic parameters and knee flexion angle (KFA) were compared between the two groups. The PI-LL mismatch group was further subdivided into operative and nonoperative group. The changes in KFA with PI-LL were examined. The PI-LL mismatch group exhibited significantly greater sagittal vertical axis (SVA), pelvic tilt (PT) and KFA, and smaller LL, thoracic kyphosis (TK), and sacral slope than the PI-LL match group. PI-LL, LL, PI, SVA, and PT were significantly correlated with KFA in the PI-LL mismatch group. From baseline to 6-month follow-up, all variables were significantly different in the operative group with the exception of PI, although there was no significant difference in any variable in the nonoperative group. The magnitude of surgical correction in the PI-LL mismatch was significantly correlated with the degree of spontaneous changes in KFA, PT, and TK. The PI-LL mismatch would contribute to compensatory knee flexion during standing in patients with lumbar degenerative disease. Surgical correction of the PI-LL mismatch could lead to a spontaneous improvement of compensatory knee flexion. The degree of improvement in knee flexion depends in part on the amount of correction in the PI-LL mismatch. 3.

Full Text Available Abstract Background The Ministry of Health (MOH launched the National Reproductive Health Policy in 2005, which included recommendations regarding the use of emergency contraceptive pills (ECP. However, ECP have not yet been introduced officially in the public sector of the Lao PDR. Thus, their availability is limited. Understanding the knowledge of ECP and attitudes about their provision, barriers to use, and availability among health providers and policy makers is essential to successfully incorporate ECP into reproductive health services. Methods Qualitative research methods using in-depth interviews were employed to collect data from policy makers and health providers (auxiliary medical staff, nurses, and medical doctors. Altogether, 10 policy makers, 22 public providers, and 10 providers at private clinics were interviewed. Content analysis was applied to analyze the transcribed data. Results The majority of policy makers and health care providers had heard about ECP and supported their introduction in the public sector. However, their knowledge was poor, many expressed inconsistent attitudes, and their ability to meet the demand of potential users is limited. Conclusions There is a need to train health providers and policy makers on emergency contraception and improve their knowledge about ECP, especially regarding the correct timing of use and the availability of methods. In addition, the general public must be informed of the attributes, side effects, and availability of ECP, and policy makers must facilitate the approval of ECP by the Lao Food and Drug Administration. These interventions could lead to increased access to and demand for ECP.

Abstract The Malagasy giant pill-millipede genus Sphaeromimus de Saussure & Zehntner, 1902 is revised. Seven new species, S. titanus sp. n., S. vatovavy sp. n., S. lavasoa sp. n., S. andohahela sp. n., S. ivohibe sp. n., S. saintelucei sp. n., and S. andrahomana sp. n. were discovered, in one case with the help of sequence data, in the rainforests of southeastern Madagascar. The species are described using light- and scanning electron microscopy. A key to all 10 species of the genus is presented. All but one (S. andohahela) of the newly discovered species are microendemics each occurring in isolated forest fragments. The mitochondrial COI barcoding gene was amplified and sequenced for 18 Sphaeromimus specimens, and a dataset containing COI sequences of 28 specimens representing all Sphaeromimus species (except S. vatovavy) was analyzed. All species are genetically monophyletic. Interspecific uncorrected genetic distances were moderate (4–10%) to high (18–25%), whereas intraspecific variation is low (0–3.5%). Sequence data allowed the correct identification of three colour morphs of S. musicus, as well as the identity of a cave specimen, which although aberrant in its morphology and colouration, was genetically identical to the holotype of S. andrahoma.

Human epidermal growth factor receptor 2 (HER2) is the most crucial ErbB receptor tyrosine kinase (RTK) family member in HER2-positive (refered to HER2-overexpressing) breast cancer which are dependent on or 'addictive' to the Phosphatidylinositol-3-kinase (PI3K) pathway. HER2-related target drugs trastuzumab and lapatinib have been the foundation of treatment of HER2--positive breast cancer. This study was designed to explore the relationship between PI3K pathway activation and the sensitivity to lapatinib in HER2--positive metastatic breast cancer patients pretreated with anthracyclins, taxanes and trastuzumab. Sixty-seven HER2-positive metastatic breast cancer patients were recruited into a global lapatinib Expanded Access Program and 57 patients have primary tumor specimens available for determination of PI3K pathway status. PTEN status was determined by immunohistochemical staining and PIK3CA mutations were detected via PCR sequencing. All patients were treated with lapatinib 1250 mg/day continuously and capecitabine 1000 mg/m 2 twice daily on a 2-week-on and 1-week-off schedule until disease progression, death, withdrawal of informed consent, or intolerable toxicity. PIK3CA mutations and PTEN loss were detected in 12.3% (7/57) and 31.6% (18/57) of the patients, respectively. Twenty-two patients with PI3K pathway activation (defined as PIK3CA mutation and/or PTEN expression loss) had a lower clinical benefit rate (36.4% versus 68.6%, P = 0.017) and a lower overall response rate (9.1% versus 31.4%, P = 0.05), when compared with the 35 patients with no activation. A retrospective analysis of first trastuzumab-containing regimen treatment data showed that PI3K pathway activation correlated with a shorter median progression-free survival (4.5 versus 9.0 months, P = 0.013). PIK3CA mutations occur more frequently in elder patients for HER2-positive breast cancer. PIK3CA mutations and PTEN loss are not mutually exclusive. PI3K pathway activation resulting

Severe mismatch between pelvic incidence (PI) and lumbar lordosis (LL) leads to extra anterior displacement of the gravity line. The objective of this study is to investigate whether femoral head retroposition is a separate compensatory mechanism responsible for the extra anterior displacement. Based on the values of PI and LL, 94 patients were divided into the PI-LL match group (PI-LL ≤ 0°), the mild PI-LL mismatch group (20°> PI-LL >0°), and the severe PI-LL mismatch group (PI-LL ≥ 20°). A series of parameters including PI, LL, PI-LL, thoracic kyphosis (TK), pelvic tilt (PT), sacral slope (SS), knee flexion angle (KFA), tibial obliquity angle (TOA), sagittal vertical axis (SVA), S1 overhang, femoral head shift (FHS), and pelvic shift (PS) were measured and compared among the three groups. The severe PI-LL mismatch group exhibited significantly greater PI, PI-LL, PT, KFA, SVA, PS, and FHS, and less LL and TK, compared with the control and mild PI-LL mismatch group. The mild PI-LL mismatch group had significantly greater PI-LL, PT, KFA, TOA, and S1 overhang, and less LL and SS than the control group. SS, TOA, and S1 overhang in the severe PI-LL mismatch group differed significantly from that in the control group, but did not differ significantly from that in the mild PI-LL mismatch group. Femoral head retroposition is an entirely separate compensatory mechanism and, in this study, participated in the compensation for the anterior displacement of the gravity line induced by extra-sagittal spinal malalignment in patients with severe PI-LL mismatch.

Contemporary classification and treatment of salivary duct carcinoma (SDC) require its thorough molecular characterization. Thirty apocrine SDCs were analyzed by the Ion Ampliseq Cancer HotSpot panel v2 for mutations in 50 cancer-related genes. Mutational findings were corroborated by immunohistochemistry (eg, TP53, BRAF, β-catenin, estrogen, and androgen receptors) or Sanger sequencing/SNaPshot polymerase chain reaction. ERBB2 (HER2), PTEN, FGFR1, CDKN2A/P16, CMET, EGFR, MDM2, and PIK3CA copy number changes were studied by fluorescence in situ hybridization. TP53 mutations (15/27, 56%), PTEN loss (11/29, 38%, including 2 cases with PTEN mutation), PIK3CA hotspot mutations (10/30, 33%), HRAS hotspot mutations (10/29; 34%), and ERBB2 amplification (9/29, 31%, including 1 case with mutation) represented the 5 most common abnormalities. There was no correlation between genetic changes and clinicopathologic parameters. There was substantial overlap between genetic changes: 8 of 9 cases with ERBB2 amplification also harbored a PIK3CA, HRAS, and TP53 mutation and/or PTEN loss. Six of 10 cases with PIK3CA mutation also had an HRAS mutation. These findings provide a molecular rationale for dual targeting of mitogen-activated protein kinase and phosphoinositide 3-kinase pathways in SDC. FGFR1 amplification (3/29, 10%) represents a new potential target. On the basis of studies of breast carcinomas, the efficacy of anti-ERBB2 therapy will likely be decreased in SDC with ERBB2 amplification co-occurring with PIK3CA mutation or PTEN loss. Therefore, isolated ERBB2 testing is insufficient for theranostic stratification of apocrine SDC. On the basis of the prevalence and type of genetic changes, apocrine SDC appears to resemble one subtype of breast carcinoma-"luminal androgen receptor positive/molecular apocrine."

Full Text Available Ischemic heart diseases remain a challenge for clinicians. QiShenYiQi pills® (QSYQ has been reported to be curative during coronary heart diseases with modulation of energy metabolism as one of the underlying mechanisms. In this study, we detected the effect of QSYQ and its components on rat myocardial structure, mitochondrial respiratory chain complexes activity and energy metabolism, and heart function after 30 min of cardiac ischemia, with focusing on the contribution of each component to its potential to regulate energy metabolism. Results showed that treatment with QSYQ and all its five components protected myocardial structure from damage by ischemia. QSYQ also attenuated release of myocardial cTnI, and restored the production of ATP after cardiac ischemia. AS-IV and Rb1, but not Rg1, R1, and DLA, had similar effect as QSYQ in regulation of energy metabolism. These results indicate that QSYQ may prevent ischemia-induced cardiac injury via regulation of energy metabolism, to which each of its components contributes differently.

Full Text Available Abstract Background As supplement to KRAS mutational analysis, BRAF and PIK3CA mutations as well as expression of PTEN may account for additional non-responders to anti-EGFR-MoAbs treatment. The aim of the present study was to investigate the utility as biomarkers of these mutations in a uniform cohort of patients with metastatic colorectal cancer treated with third-line cetuximab/irinotecan. Methods One-hundred-and-seven patients were prospectively included in the study. Mutational analyses of KRAS, BRAF and PIK3CA were performed on DNA from confirmed malignant tissue using commercially available kits. Loss of PTEN and EGFR was assessed by immunohistochemistry. Results DNA was available in 94 patients. The frequency of KRAS, BRAF and PIK3CA mutations were 44%, 3% and 14%, respectively. All were non-responders. EGF receptor status by IHC and loss of PTEN failed to show any clinical importance. KRAS and BRAF were mutually exclusive. Supplementing KRAS analysis with BRAF and PIK3CA indentified additional 11% of non-responders. Patient with any mutation had a high risk of early progression, whereas triple-negative status implied a response rate (RR of 41% (p Conclusion Triple-negative status implied a clear benefit from treatment, and we suggest that patient selection for third-line combination therapy with cetuximab/irinotecan could be based on triple mutational testing.

This prospective study examines if pre-treatment with two different doses of an oral contraceptive pill (OCP) modifies significantly the hormonal profile and/or the IVF/ICSI outcome following COS with a GnRH antagonist protocol. Infertile patients were allocated to receive either OCP containing 0.03 mg of ethinylestradiol and 3 mg of drospirenone, or OCP containing 0.02 mg of ethinylestradiol and 3 mg of drospirenone prior to initiation of controlled ovarian stimulation (COS) with recombinant gonadotropins on a variable multi-dose antagonist protocol (Ganirelix), while the control group underwent COS without OCP pretreatment. Lower dose OCP was associated with recovery of FSH on day 3 instead of day 5, but the synchronization of the follicular cohort, the number of retrieved oocytes and the clinical pregnancy rate were similar to higher dose OCP.

Time-domain numerical computations of electromagnetic fields in cylindrical co-ordinates using the transmission line matrix: evaluation of radiaion losses from a charge bunch passing through a pill-box resonator

Sarma, J.; Robson, P.N.

The two dimensional transmission line matrix (TLM) numerical method has been adapted to compute electromagnetic field distributions in cylindrical co-ordinates and it is applied to evaluate the radiation loss from a charge bunch passing through a 'pill-box' resonator. The computer program has been developed to calculate not only the total energy loss to the resonator but also that component of it which exists in the TM 010 mode. The numerically computed results are shown to agree very well with the analytically derived values as found in the literature which, therefore, established the degree of accuracy that is obtained with the TLM method. The particular features of computational simplicity, numerical stability and the inherently time-domain solutions produced by the TLM method are cited as additional, attractive reasons for using this numerical procedure in solving such problems.

Full Text Available Jill Howdyshell lives and teaches 5th grade in Togiak, a small Yu’pik fishing village in southwestern Alaska. In Togiak, harvesting berries is a practice that goes back countless generations. The berries are the key ingredient in akutaq, called eskimo ice cream. In her classes, Howdyshell’s students write identity poems with lines proclaiming “I am from akutaq,” and describing cherished excursions with parents and grandparents. In 2014, residents discovered that there would be no berries that year: the tundra had not frozen for a sufficient length of time for the berries to regenerate. With a dramatic rise in temperatures, Yu’pik people can no longer rely on digging deep into the permafrost to store food in makeshift freezers. And most distressing: as a result of rising seas, during the next few years, Yu’pik people will be forced to relocate large parts of their community.

Our aim was to evaluate the predictive and prognostic influence of BRAF mutation and other molecular, clinical and laboratory parameters in stage IV colorectal cancer (CRC). 60 patients were included in this retrospective analysis, and 17 variables were examined for their relation with treatment response and survival. KRAS mutation was identified in 40.3 % of cases, BRAF and PIK3CA in 8.8 % and 10.5 % respectively. 29.8 % of patients responded to treatment. Median survival time was 14.3 months. Weight loss, fever, abdominal metastases, blood transfusion, hypoalbuminaimia, BRAF and PIK3CA mutations, CRP and DNA Index were associated with survival. In multivariate analysis, male patients had 3.8 times higher probability of response, increased DNA Index was inversely correlated with response and one unit raise of DNA Index augmented 6 times the probability of death. Our findings potentiate the prognostic role of BRAF, PIK3CA mutations and ploidy in advanced CRC.

Tamoxifen from Failed Contraceptive Pill to Best-Selling Breast Cancer Medicine: A Case-Study in Pharmaceutical Innovation

Full Text Available Today, tamoxifen is one of the world's best-selling hormonal breast cancer drugs. However, it was not always so. Compound ICI 46,474 (as it was first known was synthesized in 1962 within a project to develop a contraceptive pill in the pharmaceutical laboratories of ICI (now part of AstraZeneca. Although designed to act as an anti-estrogen, the compound stimulated, rather than suppressed ovulation in women. This, and the fact that it could not be patented in the USA, its largest potential market, meant that ICI nearly stopped the project. It was saved partly because the team's leader, Arthur Walpole, threatened to resign, and pressed on with another project: to develop tamoxifen as a treatment for breast cancer. Even then, its market appeared small, because at first it was mainly used as a palliative treatment for advanced breast cancer. An important turning point in tamoxifen's journey from orphan drug to best-selling medicine occurred in the 1980s, when clinical trials showed that it was also useful as an adjuvant to surgery and chemotherapy in the early stages of the disease. Later, trials demonstrated that it could prevent its occurrence or re-occurrence in women at high risk of breast cancer. Thus, it became the first preventive for any cancer, helping to establish the broader principles of chemoprevention, and extending the market for tamoxifen and similar drugs further still. Using tamoxifen as a case study, this paper discusses the limits of the rational approach to drug design, the role of human actors, and the series of feedback loops between bench and bedside that underpins pharmaceutical innovation. The paper also highlights the complex evaluation and management of risk that are involved in all therapies, but more especially perhaps in life-threatening and emotion-laden diseases like cancer.

Awareness and attitudes towards emergency contraceptive pills among young people in the entertainment places, Vientiane City, Lao PDR

Science.gov (United States)

2013-01-01

Background Emergency Contraception is not officially available to the public sector in Laos. The potential of emergency contraception to prevent unwanted pregnancies is well documented in developed countries, but in Laos no studies of ECPs exist. This study aimed to assess knowledge of and attitudes towards emergency contraceptive pills (ECPs) in Vientiane, the capital city of the Lao PDR. Methods A cross-sectional survey was conducted among 500 young adults in entertainment venues by using the convenience sampling between May to July, 2007. Data were obtained through face-to-face interview. Participants were asked about socio- demographic characteristics, knowledge, attitudes related to ECPs, and source of information about ECPs. Data analysis was performed with chi-square test and logistic regression (p < .05). Results Only 22.4 percent of respondents had heard of ECPs and of these only 17.9 percent knew the correct time-frame for effective use. Most of the respondents (85%) agreed on the need for ECPs to be available in Laos and 66.8 percent stated that they would use them should the need arise, if they were available. Among those who said they would not use ECPs, 63.8 percent were concerned about possible health effects, or other side effects. Awareness of ECPs was associated with increasing age (OR = 2.78, p = .025) and male sex (OR = 2.91, p = .010). Conclusions There is needed to provide effective health education about the method, timing of use, and how to obtain ECPs through both informal, peer channels, and also through formal channels such as health care providers.

Zishen pill (ZSP) is a traditional Chinese medicine (TCM) used to treat benign prostatic hyperplasia (BPH). The study used a metabolomic approach based on UHPLC-MS/MS to profile arachidonic acid (AA) metabolic changes and to investigate the interventional mechanisms of ZSP in testosterone- induced BPH rats. In order to explore the potential therapeutic effect of ZSP, rat models were constructed and orally administrated with ZSP. Plasma and urine samples were collected after four weeks and then eleven potential biomarkers (15-HETE, 12-HETE, TXA2, 5-HETE, AA, PGI2, PGF2α, 8-HETE, PGD2, PGE2 and LTB4) were identified and quantified by UHPLC-MS/MS. The chromatographic separation was carried out with gradient elution using a mobile phase comprised of 0.05% formic acid aqueous solution (pH=3.3) (A) and acetonitrile: methanol (80:20, V/V) (B), and each AA metabolites was measured using electrospray ionization source with negative mode and multiple reaction monitoring. The eleven biomarkers in BPH group rat plasma and urine were significant higher than those in sham group rats. Using the potential biomarkers as a screening index, the results suggest that ZSP can potentially reverse the process of BPH by partially regulating AA metabolism through refrain the expression of cyclooxygenase (COX) and lipoxygenase (LOX). This study demonstrates that a metabolomic strategy is useful for identifying potential BPH biomarkers and investigating the underlying mechanisms of a TCM in BPH treatment.

The current US opioid epidemic is attributed to the large volume of prescribed opioids. This study analyzed the contribution of different medical specialties to overall opioids by evaluating the pill counts and morphine milligram equivalents (MMEs) of opioid prescriptions, stratified by provider specialty, and determined temporal trends. This was an analysis of the Ohio prescription drug monitoring program database, which captures scheduled medication prescriptions filled in the state as well as prescriber specialty. We extracted prescriptions for pill versions of opioids written in the calendar years 2010 to 2014. The main outcomes were the number of filled prescriptions, pill counts, MMEs, and extended-released opioids written by physicians in each specialty, and annual prescribing trends. There were 56,873,719 prescriptions for the studied opioids dispensed, for which 41,959,581 (73.8%) had prescriber specialty type available. Mean number of pills per prescription and MMEs were highest for physical medicine/rehabilitation (PM&R; 91.2 pills, 1,532 mg, N = 1,680,579), anesthesiology/pain (89.3 pills, 1,484 mg, N = 3,261,449), hematology/oncology (88.2 pills, 1,534 mg, N = 516,596), and neurology (84.4 pills, 1,230 mg, N = 573,389). Family medicine (21.8%) and internal medicine (17.6%) wrote the most opioid prescriptions overall. Time trends in the average number of pills and MMEs per prescription also varied depending on specialty. The numbers of pills and MMEs per opioid prescription vary markedly by prescriber specialty, as do trends in prescribing characteristics. Pill count and MME values define each specialty's contribution to overall opioid prescribing more accurately than the number of prescriptions alone.

Alkaline phosphatase conjugated magnetic microspheres were synthesized via amide reaction, and employed as an effective adsorbent in affinity selection of binding ligands followed by UHPLC-Q-TOF/MS analysis. The analytical validity of the developed approach was evaluated under optimized conditions and the following figures of merit were obtained: linearity, 0.01-0.5 g L -1 with good determination coefficients (R 2  = 0.9992); limits of detection (LODs), 0.003 g L -1 ; and limits of quantitation (LOQ), 0.01 g L -1 . The precision (RSD%) of the proposed affinity selection approach was studied based on intra-day (0.8%) and inter-day (1.3%) precisions. Finally, the adsorbent was successfully applied to identification of binding ligands in Li-Dan-Hua-Shi pills and good recoveries were obtained in the range from 96.9 to 99.4% (RSDs 1.6-3.0%).

Phosphoinositide 3-kinases (PI3K) have long been considered promising drug targets for the treatment of inflammatory and autoimmune disorders as well as cancer and cardiovascular diseases. But the lack of specificity, isoform selectivity and poor biopharmaceutical profile of PI3K inhibitors have so far hampered rigorous disease-relevant target validation. Here we describe the identification and development of specific, selective and orally active small-molecule inhibitors of PI3Kgamma (encoded by Pik3cg). We show that Pik3cg(-/-) mice are largely protected in mouse models of rheumatoid arthritis; this protection correlates with defective neutrophil migration, further validating PI3Kgamma as a therapeutic target. We also describe that oral treatment with a PI3Kgamma inhibitor suppresses the progression of joint inflammation and damage in two distinct mouse models of rheumatoid arthritis, reproducing the protective effects shown by Pik3cg(-/-) mice. Our results identify selective PI3Kgamma inhibitors as potential therapeutic molecules for the treatment of chronic inflammatory disorders such as rheumatoid arthritis.

Organizadores e cortadores de comprimidos: riscos e restrições ao uso Organizadores y cortadores de comprimidos: riesgos y restricciones del uso Pill organizers and pill cutters: risks and limitations

use of pill organizers and cutters are discussed and analyzed as a matter of public health. The use of the organizers for storing and carrying tablets and capsules exposes these medications to environmental factors from which their original packaging protected them, compromising their stability and safeness. Cutters also pose the additional risk of causing loss of efficacy, adverse reactions and overdose. On the other hand, the user carrying their own medication reflects the balance between autonomy and self-care, and splitting is sometimes required to comply with certain regimens. It can be concluded that healthcare professionals should observe and guide patients and caregivers in order to avoid risks.

Postinor -- the unique method of emergency contraception developed in Hungary.

Science.gov (United States)

Camp, S

1995-08-01

In Hungary, an important form of emergency contraception (EC) is the pill containing 0.75 mg levonorgestrel, which is marketed by Gedeon Richter under the name Postinor in four-pill packages. Women are instructed to take one pill within an hour of any unprotected act of intercourse, up to four pills per month. The nature of the administration requires that women be in possession of the pills before they need them, and, while Postinor is marketed as an EC, the target market is young, unmarried women who experience infrequent intercourse. When it was first offered a decade ago, Postinor gained widespread use in place of contraception. The product was overused and there was a backlash in the medical community. Thus, the manufacturer changed its packaging instructions and removed the original 10-pill package from the market. While the price of the drug is considered prohibitive for use by adolescents, more than three million pills were sold in the past three years in Hungary and more than 60 million pills were sold in over 20 countries. Clinical studies show a failure rate of less than 1% and relatively few side effects (10-20% nausea and 20-40% bleeding) if not more than four pills per month are used. The World Health Organization is currently conducting trials to compare use of Postinor with the Yuzpe method. Results of these trials will be available in 1996.

Millions of women use hormonal contraception and it has been suggested that such use may alter mate preferences. To examine the impact of oral contraceptive (pill) use on preferences, we tested for within-subject changes in preferences for masculine faces in women initiating pill use. Between two sessions, initiation of pill use significantly decreased women's preferences for male facial masculinity but did not influence preferences for same-sex faces. To test whether altered preference during pill use influences actual partner choice, we examined facial characteristics in 170 age-matched male partners of women who reported having either been using or not using the pill when the partnership was formed. Both facial measurements and perceptual judgements demonstrated that partners of women who used the pill during mate choice have less masculine faces than partners of women who did not use hormonal contraception at this time. Our data (A) provide the first experimental evidence that initiation of pill use in women causes changes in facial preferences and (B) documents downstream effects of these changes on real-life partner selection. Given that hormonal contraceptive use is widespread, effects of pill use on the processes of partner formation have important implications for relationship stability and may have other biologically relevant consequences.

Estradiol and Antagonist Pretreatment Prior to Microdose Leuprolide in in Vitro Fertilization. Does It Improve IVF Outcomes in Poor Responders as Compared to Oral Contraceptive Pill?

Science.gov (United States)

Elassar, Alyaa; Nulsen, John; Engmann, Lawrence; Benadiva, Claudio

2015-01-01

To compare in vitro fertilization (IVF) outcomes in low responders stimulated with microdose leuprolide protocol (ML) following pretreatment with either oral contraceptive pill (OCP) or luteal estradiol (E2) + GnRH antagonist (E2 + antag) for follicular synchronization prior to controlled ovarian hyperstimulation (COH). This was a retrospective study of 130 women, who were poor responders, undergoing IVF with either OCP/ML or E2+ antag/ML protocols. The main outcome measures were ongoing pregnancy rates, number of oocytes retrieved, and cancellation rate. Both groups were similar in baseline characteristics. There were no significant differences in gonadotropin requirement, cancellation rate, and number of embryos transferred. Ongoing pregnancy rates (40% vs. 15%) were significantly higher in the OCP/ML group. Trends toward greater number of oocytes retrieved (7.7 ± 3.4 vs. 5.9 ± 4.2) and improved implantation rates (20% vs. 12%) were also noted, but these did not reach statistical significance. E2+antag pretreatment does not appear to improve IVF outcomes in ML protocol when compared to the standard OCP in poor responders. Randomized trials with adequate power to study the optimal method of steroid pretreatments appear justified.

To study the protective effect of Qilin Pills (QLP) on the reproductive function of rats with oligoasthenospermia (OAS) induced by tripterygium glycosides. Twenty-eight male SD rats were randomly divided into a normal control, an OAS model control, a low-dose QLP, and a high-dose QLP group of equal number. OAS models were made in the latter three groups by intragastrical administration of tripterygium glycosides at 40 mg per kg of the body weight per day, and meanwhile the animals in the low- and high-dose QLP groups were treated with QLP at 1.62 and 3.24 g per kg of the body weight per day, respectively, while those in the OAS model group with normal saline, all for 30 consecutive days. Then all the rats were executed for obtaining the testis weight, testis viscera index, epididymal sperm concentration and motility, reproductive hormone levels, and antioxidation indexes and observation of the histomorphological changes of the testis tissue by HE staining. After 30 days of intervention, the low- and high-dose QLP groups, as compared with the OAS model controls, showed significantly improved epididymal sperm concentration (［14.57 ± 3.95］ and ［39.71 ± 11.31］ vs ［4.71 ± 1.25］ ×10⁶/ml, P <0.05) and motility (［3.71 ± 1.11］ and ［4.29 ± 1.80］ vs ［0.57 ± 0.53］%, P <0.05), increased levels of sex hormone binding globulin (SHBG) (［94.83 ± 11.17］ and ［88.05 ± 9.21］ vs ［56.74 ± 8.29］ nmol/L, P <0.05) and free testosterone (FT) (［27.27 ± 3.63］ and ［32.80 ± 2.51］ vs ［22.81 ± 2.75］ nmol/L, P <0.05), decreased level of follicle-stimulating hormone (FSH) (［1.49 ± 0.62］ and ［1.12 ± 0.83］ vs ［1.71 ± 0.52］ mIU/ml, P <0.05), but no significant change in the total testosterone (TT) level. Meanwhile, the level of superoxide dismutase (SOD) was markedly elevated in the low- and high-dose QLP groups in comparison with the OAS model control group (［277.14 ± 15.84］ and ［299.60 ± 20.83］ vs ［250.04 ± 31

The present study was designed to improve storage stability and oral bioavailability of Ganneng dropping pills (GNDP) by transforming lignans of Herpetospermum caudigerum (HL) composed of herpetrione (HPE) and herpetin (HPN) into nanosuspension (HL-NS), the main active ingredient of GNDP, HL-NS was prepared by high pressure homogenization and lyophilized to transform into solid nanoparticles (HL nanoparticles), and then the formulated HL nanoparticles were perfused into matrix to obtain NS-GNDP by melting method. For a period of 3 months, the content uniformity, storage stability and pharmacokinetics test in vivo of NS-GNDP were evaluated and compared with regular GNDP at room temperature. The results demonstrated that uniformity of dosage units of NS-GNDP was acceptable according to the criteria of Chinese Pharmacopoeia 2015J. Physical stability of NS-GNDP was investigated systemically using photon correlation spectroscopy (PCS), zeta potential measurement, and scanning electron microscopy (SEM). There was a slight increase in particles and PI of HL-NS re-dispersed from NS-GNDP after storage for 3 months, compared with new formulated NS-GNDP, which indicated a good redispersibility of the NS-GNDP containing HL-NS after storage. Besides, chemical stability of NS-GNDP was studied and the results revealed that HPE and HPN degradation was less when compared with that of GNDP, providing more than 99% of drug residue after storage for 3 months. In the dissolution test in vitro, NS-GNDP remarkably exhibited an increased dissolution velocity compared with GNDP and no distinct dissolution difference existed within 3 months. The pharmacokinetic study showed that HPE and HPN in NS-GNDP exhibited a significant increase in AUC 0-t , C max and decrease in T max when compared with regular GNDP. These results indicated that NS-GNDP possessed superiority with improved storage stability and increased dissolution rate and oral bioavailability. Copyright © 2018 China Pharmaceutical

Oral gavage dosing can induce stress and potentially confound experimental measurements, particularly when blood pressure and heart rate are endpoints of interest. Thus, we developed a pill formulation that mice would voluntarily consume and tested the hypothesis that pill dosing would be significantly less stressful than oral gavage. C57Bl/6 male mice were singly housed and on four consecutive days were exposed to an individual walking into the room (week 1, control), a pill being placed into the cage (week 2), and a dose of water via oral gavage (week 3). Blood pressure and heart rate were recorded by radiotelemetry continuously for 5 h after treatment, and feces collected 6–10 h after treatment for analysis of corticosterone metabolites. Both pill and gavage dosing significantly increased mean arterial pressure (MAP) during the first hour, compared to control. However, the increase in MAP was significantly greater after gavage and remained elevated up to 5 h, while MAP returned to normal within 2 h after a pill. Neither pill nor gavage dosing significantly increased heart rate during the first hour, compared to control; however, pill dosing significantly reduced heart rate while gavage significantly increased heart rate 2–5 h post dosing. MAP and heart rate did not differ 24 h after dosing. Lastly, only gavage dosing significantly increased fecal corticosterone metabolites, indicating a systemic stress response via activation of the hypothalamic–pituitary–adrenal axis. These data demonstrated that this pill dosing method of mice is significantly less stressful than oral gavage. -- Highlights: ► Developed a novel oral dosing method using a pill that mice will readily consume. ► Assessed stress by blood pressure, heart rate, and fecal corticosterone metabolites. ► Demonstrated that pill dosing is significantly less stressful than oral gavage.

Full Text Available Julian Segura, Luis Miguel Ruilope Department of Nephrology, Hospital 12 de Octubre, Madrid, Spain Abstract: This review discusses the rationale for earlier use of single-pill combinations (SPCs of antihypertensive drugs, with a focus on telmisartan/amlodipine (T/A and telmisartan/hydrochlorothiazide (T/H SPCs. Compared with the respective monotherapies, the once-daily T/A and T/H SPCs have been shown to result in significantly higher blood pressure (BP reductions, BP goal rates, and response rates in patients at all stages of hypertension. As expected, BP reductions are highest with the highest dose (T80/A10 and T80/H25 SPCs. Subgroup analyses of the telmisartan trials have reported the efficacy of both SPCs to be consistent, regardless of the patients' age, race, and coexisting diabetes, obesity, or renal impairment. In patients with mild-to-moderate hypertension, the T/A combination provides superior 24-hour BP-lowering efficacy compared with either treatment administered as monotherapy. Similarly, the T/H SPC treatment provides superior 24-hour BP-lowering efficacy, especially in the last 6 hours relative to other renin–angiotensin system inhibitor-based SPCs. The T/A SPC is associated with a lower incidence of edema than amlodipine monotherapy, and the T/H SPC with a lower incidence of hypokalemia than hydrochlorothiazide monotherapy. Existing evidence supports the use of the T/A SPC for the treatment of hypertensive patients with prediabetes, diabetes, or metabolic syndrome, due to the metabolic neutrality of both component drugs, and the use of the T/H SPC for those patients with edema or in need of volume reduction.

To compare the knowledge and the willingness of emergency physicians and gynaecologists caring for women in Italian emergency departments (EDs) to prescribe levonorgestrel-only emergency contraceptive pills (LNG-EC pills). A cross-sectional survey was conducted in 2009; anonymous postal questionnaires were mailed to the medical staff working at the 30 EDs located in Piedmont (Italy). Emergency physicians and gynaecologists have similar knowledge of the pharmacokinetics and pharmacodynamics of LNG-EC pills, but do not feel at ease in prescribing these and consider the prescription of LNG-EC pills an inappropriate activity for ED staff. In Italy, unlike in most other European countries, LNG-EC pills are still prescription drugs. Thus it may be useful to further investigate the reasons why Italian ED medical staff do not feel the prescription of LNG-EC pills should be within their remit and whether women can successfully obtain the prescription from physicians working in other services that can be accessed around the clock.

Adult spinal deformity (ASD) classification showing that ideal pelvic incidence minus lumbar lordosis (PI-LL) value is within 10° has been received widely. But no study has focused on the optimum level of PI-LL value that reflects wide variety in PI among patients. This study was conducted to determine the optimum PI-LL value specific to an individual's PI in postoperative ASD patients. 48 postoperative ASD patients were recruited. Spino-pelvic parameters and Oswestry Disability Index (ODI) were measured at the final follow-up. Factors associated with good clinical results were determined by stepwise multiple regression model using the ODI. The patients with ODI under the 75th percentile cutoff were designated into the "good" health related quality of life (HRQOL) group. In this group, the relationship between the PI-LL and PI was assessed by regression analysis. Multiple regression analysis revealed PI-LL as significant parameters associated with ODI. Thirty-six patients with an ODI <22 points (75th percentile cutoff) were categorized into a good HRQOL group, and linear regression models demonstrated the following equation: PI-LL = 0.41PI-11.12 (r = 0.45, P = 0.0059). On the basis of this equation, in the patients with a PI = 50°, the PI-LL is 9°. Whereas in those with a PI = 30°, the optimum PI-LL is calculated to be as low as 1°. In those with a PI = 80°, PI-LL is estimated at 22°. Consequently, an optimum PI-LL is inconsistent in that it depends on the individual PI.

Lobular carcinoma in situ (LCIS) has been proposed as a non-obligate precursor of invasive lobular carcinoma (ILC). Here we sought to define the repertoire of somatic genetic alterations in pure LCIS and in synchronous LCIS and ILC using targeted massively parallel sequencing. DNA samples extracted from microdissected LCIS, ILC and matched normal breast tissue or peripheral blood from 30 patients were subjected to massively parallel sequencing targeting all exons of 273 genes, including the genes most frequently mutated in breast cancer and DNA repair-related genes. Single nucleotide variants and insertions and deletions were identified using state-of-the-art bioinformatics approaches. The constellation of somatic mutations found in LCIS (n = 34) and ILC (n = 21) were similar, with the most frequently mutated genes being CDH1 (56% and 66%, respectively), PIK3CA (41% and 52%, respectively) and CBFB (12% and 19%, respectively). Among 19 LCIS and ILC synchronous pairs, 14 (74%) had at least one identical mutation in common, including identical PIK3CA and CDH1 mutations. Paired analysis of independent foci of LCIS from 3 breasts revealed at least one common mutation in each of the 3 pairs (CDH1, PIK3CA, CBFB and PKHD1L1). LCIS and ILC have a similar repertoire of somatic mutations, with PIK3CA and CDH1 being the most frequently mutated genes. The presence of identical mutations between LCIS-LCIS and LCIS-ILC pairs demonstrates that LCIS is a clonal neoplastic lesion, and provides additional evidence that at least some LCIS are non-obligate precursors of ILC.

Full Text Available BACKGROUND: We previously reported that the addition of erlotinib to gemcitabine and oxaliplatin (GEMOX resulted in greater antitumor activity and might be a treatment option for patients with biliary tract cancers (BTCs. Molecular subgroup analysis of treatment outcomes in patients who had specimens available for analysis was undertaken. METHODS: Epidermal growth factor receptor (EGFR, KRAS, and PIK3CA mutations were evaluated using peptide nucleic acid–locked nucleic acid polymerase chain reaction clamp reactions. Survival and response rates (RRs were analyzed according to the mutational status. Sixty-four patients (48.1% were available for mutational analysis in the chemotherapy alone group and 61 (45.1% in the chemotherapy plus erlotinib group. RESULTS: 1.6% (2/116 harbored an EGFR mutation (2 patients; exon 20, 9.6% (12/121 harbored a KRAS mutation (12 patients; exon 2, and 9.6% (12/118 harbored a PIK3CA mutation (10 patients, exon 9 and 2 patients, exon 20. The addition of erlotinib to GEMOX in patients with KRAS wild-type disease (n = 109 resulted in significant improvements in overall response compared with GEMOX alone (30.2% vs 12.5%, P = .024. In 95 patients with both wild-type KRAS and PIK3CA, there was evidence of a benefit associated with the addition of erlotinib to GEMOX with respect to RR as compared with GEMOX alone (P = .04. CONCLUSION: This study demonstrates that KRAS mutational status might be considered a predictive biomarker for the response to erlotinib in BTCs. Additionally, the mutation status of PIK3CA may be a determinant for adding erlotinib to chemotherapy in KRAS wild-type BTCs.

Full Text Available Phosphoinositides, lipid-signaling molecules, participate in diverse brain processes within a wide metabolic cascade.Gene transcriptional networks coordinately regulate the phosphoinositide cascade during human brain Development and Aging.We used the public BrainCloud database for human dorsolateral prefrontal cortex to examine age-related expression levels of 49 phosphoinositide metabolic genes during Development (0 to 20+ years and Aging (21+ years.We identified three groups of partially overlapping genes in each of the two intervals, with similar intergroup correlations despite marked phenotypic differences between Aging and Development. In each interval, ITPKB, PLCD1, PIK3R3, ISYNA1, IMPA2, INPPL1, PI4KB, and AKT1 are in Group 1, PIK3CB, PTEN, PIK3CA, and IMPA1 in Group 2, and SACM1L, PI3KR4, INPP5A, SYNJ1, and PLCB1 in Group 3. Ten of the genes change expression nonlinearly during Development, suggesting involvement in rapidly changing neuronal, glial and myelination events. Correlated transcription for some gene pairs likely is facilitated by colocalization on the same chromosome band.Stable coordinated gene transcriptional networks regulate brain phosphoinositide metabolic pathways during human Development and Aging.

QiShenYiQi dripping pills (QSYQ), a traditional Chinese medicine, are commonly used to treat coronary heart disease, and QSYQ was recently approved as a complementary treatment for ischemic heart failure in China. However, only few studies reported on whether QSYQ exerts a protective effect on heart failure induced by pressure overload. In this study, we explored the role of QSYQ in a mouse model of heart failure induced by transverse aortic constriction (TAC). Twenty-eight C57BL/6J mice were divided into four groups: Sham + NS group, Sham + QSYQ group, TAC + NS group, and TAC + QSYQ group. QSYQ dissolved in normal saline (NS) was administered intragastrically (3.5 mg/100 g/day) in the Sham + QSYQ and TAC + QSYQ groups. In the Sham + NS and TAC + NS groups, NS was provided every day intragastrically. Eight weeks after TAC, echocardiography, and cardiac catheterization were performed to evaluate the cardiac function, and immunofluorescent staining with anti-actinin2 antibody was performed to determine the structure of the myocardial fibers. Moreover, TUNEL staining and Masson trichrome staining were employed to assess the effects of QSYQ on cardiac apoptosis and cardiac fibrosis. Western blots and real-time polymerase chain reaction (PCR) were used to measure the expression levels of vascular endothelial growth factor (VEGF) in the heart, and immunohistochemical staining with anti-CD31 antibody was performed to explore the role of QSYQ in cardiac angiogenesis. Results showed that TAC-induced cardiac dysfunction and disrupted structure of myocardial fibers significantly improved after QSYQ treatment. Moreover, QSYQ treatment also significantly improved cardiac apoptosis and cardiac fibrosis in TAC-induced heart failure, which was accompanied by an increase in VEGF expression levels and maintenance of microvessel density in the heart. In conclusion, QSYQ exerts a protective effect on TAC-induced heart failure, which could be attributed to enhanced cardiac angiogenesis

Yougui pills (YGPs) have been used for centuries in the treatment of Chinese patients with Kidney-Yang Deficiency Syndrome. Despite the fact that the efficiency of YGPs on treating osteoarthritis has been verified in clinic, the underlying mechanisms are not totally understood. The present study observes the therapeutic role of YGPs and mechanisms underlying its chondroprotective action in osteoarthritic cartilage. To evaluate the chondroprotective effects of YGPs, we examined the impact of orally administered YGPs in a model of destabilization of the medial meniscus (DMM). Male C57BL/6J mice were provided a daily treatment of YGPs and a DMM surgery was performed on the right knee. At 12 weeks post-surgery, the joints were harvested for tissue analyses, including histomorphometry, OARSI scoring, micro-CT and immunohistochemistry for COL-2, MMP-13 and pSMAD-2. We also performed the relative experiments mentioned above in mice with Tgfbr2 conditional knockout ( TGF-βRII Col2ER mice) in articular cartilage. To evaluate the safety of YGPs, hematology was determined in each group. Amelioration of cartilage degradation was observed in the YGPs group, with increases in cartilage area and thickness, proteoglycan matrix, and decreases in OARSI score at 12 weeks post surgery. In addition, reduced BV/TV and Tb. Th, and elevated Tb. Sp were observed in DMM-induced mice followed by YGPs treatment. Moreover, the preservation of cartilage correlated with reduced MMP-13, and elevated COL-2 and pSMAD-2 protein expressional levels were also revealed in DMM-induced mice treated with YGPs. Similarly, TGF-βRII Col2ER mice exhibited significant OA-like phenotype. However, no significant difference in cartilage structure was observed in TGF-βRII Col2ER mice after YGPs treatment. Interestingly, no obvious adverse effects were observed in mice from each group based on the hematologic analyses. These findings suggested that YGPs could inhibit cartilage degradation through enhancing TGF

Full Text Available The prevalence of low birth weight (LBW in Indonesia varied between 2.1 - 17.2%. At the end of Five years Development Plan V (Repelita V it was 15.0%, and is expected to decrease to 10.0% by the end of Repelita VI. Low Birth Weight infant (less than 2500 grm is an important issue, because of its relationship with the survival and health status of the infant in the future. The prevalence of anemia in pregnant women is 63.5%. The cause of anemia is mostly iron deficiency. The need of iron in pregnant women is quite high which is an average of 800 mg during pregnancy. Daily food contains 10 - 20 mg iron but the human body can absorb only less than 10.0%. To overcome the problem, iron pills distribution program is implemented. The iron pills contain 200 mg ferro sulfate and 0.25 mg folic acid, and are given to all pregnant women who visit Community Health Centres (Puskesmas and Integrated Health Service Posts (Posyandu. Each pregnant women is expected to have at least 90 iron pills during the pregnancy. The objective of further analysis of the Demographic and Health Survey 1994 is to obtain information on the impact of iron pills on low birth weight. Among the 1689 weighted children born in 1994, there were 6.7% (112 children with low birth weight. The percentage of low birth weight (10.6% in the mothers who did not take the iron pills is the highest, followed by mothers who took less than 90 pills (6.0% and the lowest percentage of low birth weight is found among mothers who took the least iron pills (5.9%, and statistically the difference is significant at p=0.0271. Among mothers who weighted their new born children, 14.6% did not take iron pills during pregnancy, only 26.1% mothers who took at least 90 iron pills during pregnancy. There is variation among the number of iron pills taken. Iron pill is useful for pregnant women. Based on the pills consumed by the pregnant women, the risk for having low birth weight infant for mother who did not take

Full Text Available Abstract Background Unsafe abortion is a major public health problem in low-and-middle income countries. Young and unmarried women constitute a high risk group for unsafe abortions. It has been estimated that widespread use of emergency contraception may significantly reduce the number of abortion-related morbidity and mortality. The purpose of this study was to evaluate the knowledge, attitudes and experiences on emergency contraceptive pills by the university students in Cameroon in order to develop and refine a national health programme for reducing unwanted pregnancies and their associated morbidity and mortality. Methods A convenient sample of 700 students of the University of Buea (Cameroon was selected for the study. Data was collected by a self-administered, anonymous and pre-tested questionnaire. Results The response rate was 94.9% (664/700. General level of awareness of emergency contraceptive pills was 63.0% (418/664. However, knowledge of the general features of emergency contraceptive pills was low and misinformation was high among these students. Knowledge differed according to the source of information: informal source was associated with misinformation, while medical and informational sources were associated with better knowledge. Although the students generally had positive attitudes regarding emergency contraceptive pills, up to 65.0% (465/664 believed that emergency contraceptive pills were unsafe. Those with adequate knowledge generally showed favourable attitudes with regards to emergency contraceptive pills (Mann-Whitney U = 2592.5, p = 0.000. Forty-nine students (7.4% had used emergency contraceptive pills themselves or had a partner who had used them. Conclusion Awareness of emergency contraception pills by Cameroonian students is low and the method is still underused. Strategies to promote use of emergency contraception should be focused on spreading accurate information through medical and informational sources, which

Full Text Available Objectives. To assess the effectiveness and adverse effects of adding Liuwei Dihuang Pills (LDP to Western medicine for treating diabetic nephropathy. Methods. Studies were retrieved from seven electronic databases, including PubMed, Embase, The Cochrane Library, CBM, CNKI, Chinese Scientific Journal Database (VIP, and Wanfang Data until November 2015. Study selection, data extraction, quality assessment, and data analyses were conducted according to Cochrane standards. Meta-analysis was performed on the overall therapeutic efficacy of hyperglycemia and renal functions, and the study also analyzed adverse events. Results. A total of 1,275 patients from 18 studies were included. The methodological quality of these included trials was generally low. We found that adding LDP can lower patients’ FBG (MD: −0.36 [−0.46, −0.25], P<0.00001, PBG (MD: −1.10 [−1.35, −0.85], P<0.00001, and HbA1c (MD: −0.14 [−0.49, 0.21], P=0.43. There were also improvements in lowering patients’ BUN (MD: −0.67 [−0.89, −0.45], P<0.00001, SCr (MD: −0.96 [−1.53, −0.39], P<0.00001, 24 h UTP (SMD: −1.26 [−2.38, −0.15], P<0.00001, UAER (MD: −26.18 [−27.51, −24.85], P<0.00001, and UmAlb (SMD: −1.72 [−2.67, −0.77], P<0.00001. Conclusion. There is encouraging evidence that adding LDP to Western medicine might improve treatment outcomes of diabetic nephropathy, including hyperglycemia and renal functions. However, the evidence remains weak. More rigorous high-quality trials are warranted to substantiate or refute the results.

In this study, a rapid and reliable ultra-fast liquid chromatography-tandem mass spectrometry method was developed and validated for the simultaneous determination of eight active ingredients, including astragaloside IV, ononin, tanshinol, protocatechualdehyde, protocatechuic acid, salvianolic acid D, rosmarinic acid and ginsenoside Rg 1 , in rat plasma. The plasma samples were pretreated by protein precipitation with acetonitrile. Chromatographic separation was performed on a Waters Acquity UPLC® BEH C 18 column (1.7 μm particles, 2.1 × 100 mm). The mobile phase consisted of 0.1% aqueous formic acid (A)-acetonitrile with 0.1% formic acid (B) at a flow rate of 0.4 mL/min. Quantification was performed on a triple quadruple tandem mass spectrometry with electrospray ionization by multiple reaction monitoring both in the negative and in the positive ion mode. The lower limit of quantification of tanshinol was 2.0 ng/mL and the others were 5.0 ng/mL. The extraction recoveries, matrix effects, intra- and inter-day precision and accuracy of eight tested components were all within acceptable limits. The validated method was successfully applied to the pharmacokinetic study of the eight active constituents after intragastric administration of three doses (1.0, 3.0, 6.0 g/kg body weight) of Qishen Yiqi Dripping Pills to rats.

Direct analysis in real-time mass spectrometry (DART-MS) with in situ silylation was used for the rapid analysis of the flavonoids silybin ((2R,3R)-3,5,7-trihydroxy-2-[3-(4-hydroxy-3-methoxyphenyl)-2-hydroxymethyl-2,3-dihydrobenzo[1,4]dioxin-6-yl]chroman-4-one) and rutin (quercetin-3-O-rutinoside). Three different derivatization reagents, hexamethyldisilazane/trimethylchlorosilane/pyridine (HMDS/TMCS/pyridine), N,O-bis(trimethylsilyl)acetamide/trimethylchlorosilane/N-trimethylsilyimidazole (BSA/TMCS/TMSI), and N,O-bis(trimethylsilyl)trifluoroacetamide/trimethylchlorosilane (BSTFA/TMCS), were applied. Silybin and rutin were detected with various degrees of silylation, and the formation of dimers with pyridine and imidazole was also observed. HMDS/TMCS/pyridine was the best choice for the DART-MS analysis of silybin, and BSA/TMCS/TMSI was the most effective for the detection of rutin. The effects of the DART source temperature on desorption, ionization, in-source fragmentation, dimer formation, and hydrolysis of the trimethylsilyl groups were also studied. In addition, the collision-induced dissociation properties of the derivatized silybin and rutin were explored. With our in situ silylation method, the derivatized bioactive compounds in intact medical pills could also be detected by DART-MS. Copyright © 2017 John Wiley & Sons, Ltd.

The cancer preventive activity of vitamin E is suggested by epidemiological studies and supported by animal studies with vitamin E forms, γ-tocopherol and δ-tocopherol (δ-T). Several recent large-scale cancer prevention trials with high dose of α-tocopherol, however, yielded disappointing results. Whether vitamin E prevents or promotes cancer is a serious concern. A better understanding of the molecular mechanisms of action of the different forms of tocopherols would enhance our understanding of this topic. In this study, we demonstrated that δ-T was the most effective tocopherol form in inhibiting prostate cancer cell growth, by inducing cell cycle arrest and apoptosis. By profiling the effects of δ-T on the cell signaling using the phospho-kinase array, we found that the most inhibited target was the phosphorylation of AKT on T308. Further study on the activation of AKT by EGFR and IGFR revealed that δ-T attenuated the EGF/IGF-induced activation of AKT (via the phosphorylation of AKT on T308 induced by the activation of PIK3). Expression of dominant active PIK3 and AKT in prostate cancer cell line DU145 in which PIK3, AKT, and PTEN are wild type caused the cells to be reflectory to the inhibition of δ-T, supporting that δ-T inhibits the PIK3-mediated activation of AKT. Our data also suggest that δ-T interferes with the EGF-induced EGFR internalization, which leads to the inhibition of the receptor tyrosine kinase-dependent activation of AKT. In summary, our results revealed a novel mechanism of δ-T in inhibiting prostate cancer cell growth, supporting the cancer preventive activity δ-T. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

Although the herbal pair of Euphorbia kansui (GS) and Glycyrrhiza (GC) is one of the so-called "eighteen antagonistic medicaments" in Chinese medicinal literature, it is prescribed in a classic Traditional Chinese Medicine (TCM) formula Gansui-Banxia-Tang for cancerous ascites, suggesting that GS and GC may exhibit synergistic or antagonistic effects in different combination designs. Here, we modeled the effects of GS/GC combination with a target interaction network and clarified the associations between the network topologies involving the drug targets and the drug combination effects. Moreover, the "edge-betweenness" values, which is defined as the frequency with which edges are placed on the shortest paths between all pairs of modules in network, were calculated, and the ADRB1-PIK3CG interaction exhibited the greatest edge-betweenness value, suggesting its crucial role in connecting the other edges in the network. Because ADRB1 and PIK3CG were putative targets of GS and GC, respectively, and both had functional interactions with AVPR2 approved as known therapeutic target for ascites, we proposed that the ADRB1-PIK3CG-AVPR2 signal axis might be involved in the effects of the GS-GC combination on ascites. This proposal was further experimentally validated in a H22 hepatocellular carcinoma (HCC) ascites model. Collectively, this systems-level investigation integrated drug target prediction and network analysis to reveal the combination principles of the herbal pair of GS and GC. Experimental validation in an in vivo system provided convincing evidence that different combination designs of GS and GC might result in synergistic or antagonistic effects on HCC ascites that might be partially related to their regulation of the ADRB1-PIK3CG-AVPR2 signal axis.

Comorbid psychiatric conditions present an added layer of challenge in managing patients, as each condition and associated set of symptoms exacerbate the complexity of the overall presentation. Premenopausal women may be at particular risk for inadequate care, as their comorbid conditions may present overlapping symptoms and mask independent premenstrual symptoms. The prevalence of premenstrual dysphoric disorder and associated conditions can be as high as 8% in women of reproductive age. Recognizing and assessing premenstrual symptoms that are comorbid with other psychiatric conditions can help contribute to a comprehensive treatment strategy and potentially improve the treatment response for the comorbid conditions. Combined oral contraceptive pills (COCPs) have been approved for premenstrual conditions and should be considered by the psychiatrist as an available treatment option. A 34-year-old Caucasian female patient with comorbid major depressive disorder, premenstrual dysphoric disorder, social anxiety, panic disorder, and histrionic personality disorder, with persistent suicidal ideation and distress intolerance, was treated with norgestimate-ethinyl estradiol with improvement in mood, anxiety, and menstrual cramping and with associated diminished suicidal ideation and improved distress tolerance. In this case, Beck Depression Inventory and Beck Anxiety Inventory scores, as well as self- and peer-reported functionality, all suggested improvement in symptoms following the introduction of COCPs. The neurohormonal contribution to psychiatric conditions continues to be studied and is becoming increasingly important. An understanding of the presence and etiology of premenstrual symptoms should be part of a comprehensive psychiatric assessment of female patients, and consideration of COCPs in the treatment plan adds a potentially potent option for symptom mitigation and remission.
