    The performance of accelerators with high beam power or high stored beam energy is strongly dependent on the way the beam is handled, how beam parameters are measured and how the machine is commissioned. Two corresponding working groups have been organized for the Workshop: group C ''Beam diagnostics, collimation, injection/extraction and targetry'' and group G ''Commissioning strategies and procedures''. It has been realized that the issues to be discussed in these groups are interlaced with the participants involved and interested in the above topics, with an extremely important subject of beam-induced accidents as additional topic. Therefore, we have decided to combine the group sessions as well as this summary report. Status, performance and outstanding issues of each the topic are described in the sections below, with additional observations and proposals by the joint group at the end.

    Individual interviews are often considered to be the gold standard for researchers to understand how people think about phenomena. However, conducting and analyzing interviews is very time consuming. This paper presents the Group Administered Interactive Questionnaire (GAIQ) as an alternative to individual interviews and discusses the pros and cons of each data collection method. Use of GAIQ will be discussed in the context of a study that seeks to understand teaching assistants' reasons for the design of problem solutions for introductory physics.

    This study entailed a 3 (instructional intervention) × 2 (assessment-type) between-subjects experimental design employing a pretest-intervention-posttest methodology. The instructional interventions were administered between subjects in three conditions: (a) dynamic instruction, (b) triarchic or theory of successful intelligence-control instruction, and (c) standard-control instruction. The assessment-type consisted between subjects of either (a) a group-administered dynamic posttest or (b) the same group-administered posttest interspersed with a control filler activity. Performance in different mathematics content areas taught in fourth grade was investigated. In total, 1,332 students and 63 classroom teachers in 24 schools across six school districts participated in the study. The results indicate the advantages of using dynamic instruction and assessment in regular classrooms while teaching mathematics, especially when the student body is highly ethnically diverse.

    Full Text Available Abstract Background Internet administered cognitive behaviour therapy (CBT is a promising new way to deliver psychological treatment, but its effectiveness in regular care settings and in relation to more traditional CBT group treatment has not yet been determined. The primary aim of this study was to compare the effectiveness of Internet-and group administered CBT for panic disorder (with or without agoraphobia in a randomised trial within a regular psychiatric care setting. The second aim of the study was to establish the cost-effectiveness of these interventions. Methods Patients referred for treatment by their physician, or self-referred, were telephone-screened by a psychiatric nurse. Patients fulfilling screening criteria underwent an in-person structured clinical interview carried out by a psychiatrist. A total of 113 consecutive patients were then randomly assigned to 10 weeks of either guided Internet delivered CBT (n = 53 or group CBT (n = 60. After treatment, and at a 6-month follow-up, patients were again assessed by the psychiatrist, blind to treatment condition. Results Immediately after randomization 9 patients dropped out, leaving 104 patients who started treatment. Patients in both treatment conditions showed significant improvement on the main outcome measure, the Panic Disorder Severity Scale (PDSS after treatment. For the Internet treatment the within-group effect size (pre-post on the PDSS was Cohen's d = 1.73, and for the group treatment it was d = 1.63. Between group effect sizes were low and treatment effects were maintained at 6-months follow-up. We found no statistically significant differences between the two treatment conditions using a mixed models approach to account for missing data. Group CBT utilised considerably more therapist time than did Internet CBT. Defining effect as proportion of PDSS responders, the cost-effectiveness analysis concerning therapist time showed that Internet treatment had superior cost

    Full Text Available Objective: Dementia is a major public health problem. More and more patients with dementia are being admitted to acute care hospitals for treatment of comorbidities. Issues associated with care of patients with dementia in acute care hospitals have not been adequately clarified. This study aimed to explore the challenges nurses face in providing care to patients with dementia in acute care hospitals in Japan. Methods: This was a qualitative study using focus group interviews (FGIs. The setting was six acute hospitals with surgical and medical wards in the western region of Japan. Participants were nurses in surgical and internal medicine wards, excluding intensive care units. Nurses with less than 3 years working experience, those without experience in dementia patient care in their currently assigned ward, and head nurses were excluded from participation. FGIs were used to collect data from February to December 2008. Interviews were scheduled for 1–1.5 h. The qualitative synthesis method was used for data analysis. Results: In total, 50 nurses with an average experience of 9.8 years participated. Eight focus groups were formed. Issues in administering care to patients with dementia at acute care hospitals were divided into seven groups. Three of these groups, that is, problematic patient behaviors, recurrent problem, and problems affecting many people equally, interact to result in a burdensome cycle. This cycle is exacerbated by lack of nursing experience and lack of organization in hospitals. In coping with this cycle, the nurses develop protection plans for themselves and for the hospital. Conclusions: The two main issues experienced by nurses while administering care to patients with dementia in acute care hospitals were as follows: (a the various problems and difficulties faced by nurses were interactive and caused a burdensome cycle, and (b nurses do their best to adapt to these conditions despite feeling conflicted.

  13. Variation, evolution, and correlation analysis of C+G content and genome or chromosome size in different kingdoms and phyla.

    2014-01-01

    C+G content (GC content or G+C content) is known to be correlated with genome/chromosome size in bacteria but the relationship for other kingdoms remains unclear. This study analyzed genome size, chromosome size, and base composition in most of the available sequenced genomes in various kingdoms. Genome size tends to increase during evolution in plants and animals, and the same is likely true for bacteria. The genomic C+G contents were found to vary greatly in microorganisms but were quite similar within each animal or plant subkingdom. In animals and plants, the C+G contents are ranked as follows: monocot plants>mammals>non-mammalian animals>dicot plants. The variation in C+G content between chromosomes within species is greater in animals than in plants. The correlation between average chromosome C+G content and chromosome length was found to be positive in Proteobacteria, Actinobacteria (but not in other analyzed bacterial phyla), Ascomycota fungi, and likely also in some plants; negative in some animals, insignificant in two protist phyla, and likely very weak in Archaea. Clearly, correlations between C+G content and chromosome size can be positive, negative, or not significant depending on the kingdoms/groups or species. Different phyla or species exhibit different patterns of correlation between chromosome-size and C+G content. Most chromosomes within a species have a similar pattern of variation in C+G content but outliers are common. The data presented in this study suggest that the C+G content is under genetic control by both trans- and cis- factors and that the correlation between C+G content and chromosome length can be positive, negative, or not significant in different phyla.

    The aim of the experiment was to evaluate effects of zinc gluconate (ZnGlu) and probiotic administration on the daily rhythm of cloacal temperature (tcloacal) in broiler chickens of different age groups during the hot-dry season. One-day-old broiler chicks (n = 60) were divided into groups I-IV of 15 chicks per group, and treated for 35 days: Group I (control) was given deionized water; Group II, ZnGlu (50 mg/kg); Group III, probiotic (4.125 × 10(6 )cfu/100 mL), and Group IV, ZnGlu (50 mg/kg) + probiotic (4.125 × 10(6 )cfu/100 mL). Air dry-bulb temperature (tdb), relative humidity (RH), and temperature-humidity index (THI) inside the pen, and tcloacal of each broiler chick were obtained bihourly over a 24-h period; on days 21, 28, and 35 of the study. Values of tdb (32.10 ± 0.49°C), RH (49.94 ± 1.91%), and THI (38.85 ± 0.42) obtained were outside the thermoneutral zone for broiler chickens, and suggested that the birds were subjected to heat stress. Application of the periodic model showed disruption of daily rhythm of tcloacal in broilers on day 21, which was synchronized by probiotic administration. The administration of probiotics or ZnGlu + probiotics to a greater extent decreased the mesor and amplitude, delayed the acrophases of tcloacal in broilers, especially at day 35, as compared to the controls. Overall, the tcloacal values in broiler chickens administered with probiotic alone (41.25 ± 0.05°C) and ZnGlu + probiotic (41.52 ± 0.05°C) were lower (P heat stress on broiler chickens during the hot-dry season. © 2017 The Authors.

    Full Text Available Introduction: Hepatitis B virus (HBV infection is a major health problem worldwide and may lead to serious clinical complications, including chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. The host’s genetic background in immune system genes is a crucial etiologic factor in progression of HBV infection to chronic disease or clearance of the virus from the body. Interleukin 12 and its receptor (IL12 Receptor play an important role in the clearance of viral infections, especially HBV. The aim of this study is to investigate the association between interleukin 12 receptor B1 gene single nucleotide polymorphism (rs401502 C/G and chronic HBV infection. Methods: In this case control study, genomic DNA of 105 chronically HBV infected patients and 105 healthy controls was extracted. Genotype of (rs401502 C/G single nucleotide polymorphism was determined using polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP method. Results: The frequency of (rs401502 C/G SNP for GG, GC, CC genotypes and G, C alleles was %53.3, %41, %5.7 and %73.3, %26.7 in the chronic patients and %51.4, %41, %7.6 %71.9 , and %28.1 in the control group, respectively. Statistical analysis of the results showed that there was not any significant difference between the case and control groups (p=0.851. Conclusion: In this study, no association was found between (rs401502 C/G single nucleotide polymorphism within IL12RB1 gene and chronic hepatitis B virus infection. It seems that this SNP does not play a crucial role in susceptibility to HBV chronic infection

    Breast cancer is the most common neoplasm among Hispanic women. Cervical cancer has a higher incidence and mortality among Hispanic women compared with non-Hispanic White women. To assess the effectiveness of a promotora-administered educational intervention to promote breast and cervical cancer screening among post-reproductive age, medically underserved Hispanic women residing along the U.S.-Mexico border. Women age 50 or older were eligible to participate in this intervention study. A total of 381 subjects agreed to participate. Women were randomly assigned into one of two groups, educational intervention or usual care. The primary outcomes were self-reported mammogram and Pap smear screening. Logistic regression analysis was used to compute odds ratios for comparisons between intervention and control groups. Women in the intervention group were 2.0 times more likely to report having had a mammogram within the last year when compared with the usual care group (95% CI = 1.3-3.1). Likewise, women in the intervention group were 1.5 times more likely to report having a Pap smear within the last year when compared with the usual care group, although this was not statistically significant (95% CI = 0.9-2.6). In a secondary analysis, the intervention suggests a stronger effect on those that had not had a mammogram or Pap smear within the past year at baseline. A promotora-based educational intervention can be used to increase breast and cervical cancer screening utilization among Hispanic women.

    The OSIRIS camera aboard the Rosetta spacecraft observed the nucleus of comet 67P/C-G from the mapping phase in summer 2014 until now. The images have allowed the reconstruction in three-dimension of nucleus surface with stereophotogrammetry (Preusker et al., Astron. Astrophys.) and stereophotoclinometry (Jorda et al., Icarus) techniques. We use the reconstructed models to constrain the internal density distribution based on: (i) the measurement of the offset between the center of mass and the center of figure of the object, and (ii) the assumption that flat areas observed at the surface of the comet correspond to iso-gravity surfaces. The results of our analysis will be presented, and the consequences for the internal structure and formation of the nucleus of comet 67P/C-G will be discussed.

    Unique information about the internal structure of the nucleus of comet 67P/C-G was provided by the CONSERT bistatic radar on-board Rosetta and Philae [1]. Analysis of the propagation of its signal throughout the small lobe indicated that the real part of the permittivity at 90 MHz is of (1.27±0.05). The first interpretation of this value using dielectric properties of mixtures of dust and ices (H2O, CO2), led to the conclusion that the comet porosity ranges between 75-85%. In addition, the dust/ice ratio was found to range between 0.4-2.6 and the permittivity of dust (including 30% of porosity) was determined to be lower than 2.9.The dust permittivity estimate is now reduced by taking into account the updated values of nucleus density and of dust/ice ratio, in order of providing further insights into the nature of the constituents of comet 67P/C-G [2]. We adopt a systematic approach: i) determination of the dust permittivity as a function of the ice (I) to dust (D) and vacuum (V) volume fraction; ii) comparison with the permittivity of meteoritic, mineral and organic materials from literature and laboratory measurements; iii) test of several composition models of the nucleus, corresponding to cosmochemical end members of 67P/C-G. For each of these models the location in the ternary I/D/V diagram is calculated based on available dielectric measurements, and confronted to the locus of 67P/C-G. The number of compliant models is small and the cosmochemical implications of each are discussed [2]. An important fraction of carbonaceous material is required in the dust in order to match CONSERT permittivity observations, establishing that comets represent a massive carbon reservoir.Support from Centre National d'Études Spatiales (CNES, France) for this work, based on observations with CONSERT on board Rosetta, is acknowledged. The CONSERT instrument was designed, built and operated by IPAG, LATMOS and MPS and was financially supported by CNES, CNRS, UJF/UGA, DLR and MPS

    HLA-G is highly expressed in cancer. Also, it is associated to its progression. Here, we explored the relationship between two HLA-G polymorphisms with breast cancer (BC) and tried to make a correlation with sHLA-G levels. We genotyped 104 patients with BC and 83 controls (CTRL) for HLA-G 14-bp insertion/deletion (Ins/Del) and HLA-G +3142 C>G polymorphisms. The mutations were identified with PCR and PCR-RFLP. The sHLA-G dosage was performed on plasma samples by a specific ELISA. A significant association with BC was found concerning the G allele in the +3142 C>G polymorphism (p = 0.0004). The G/G genotype is the protective genotype (1 % in BC patients vs. 13.1 % in CTRL, OR 0.065, 95 % CI 0.008-0.523). No statistically significant differences were observed for the 14-bp Ins/Del polymorphism between BC patients and controls frequencies. The protection by G/G genotype of +3142 C>G polymorphism is maintained in young patients (G polymorphisms and BC susceptibility. Indeed, the (DelG) haplotype is found as the protective haplotype against BC (OR 0.269, 95 % CI 0.081-0.895, p = 0.023). The ELISA dosage of sHLA-G revealed increased levels in BC compared to CTRL (p G is closely associated with advanced stages of BC without significance. sHLA-G is increased in TNM IV and SBR III subgroups. It is also enhanced in patients with a tumor size over 20 mm and in triple-negative patients. Taken together, our findings demonstrate, for the first time, the association of HLA-G +3142 C>G polymorphism with BC susceptibility in Tunisian population. Our results revealed also a potential implication of sHLA-G in advanced stages of BC.

    Full Text Available Background: Recurrent pregnancy loss (RPL is defined as two or more miscarriages before the 20th week of gestation and its etiology is unknown in 50% of the cases. Interleukin 6 is an immune mediator, plays a regulatory role in embryo implantation and placental development. Objective: The purpose was to assess the association between IL-6 -634C/G polymorphism and, susceptibility to idiopathic RPL for the first time in Iran. Materials and Methods: In total 121 women with RPL and 121 healthy women as control group were enrolled in this case-control study. This study was performed from August 2013 to October 2014 in the Molecular Genetics Laboratory of Arsanjan University. Candidate polymorphism was evaluated by PCR-RFLP method on extracted genomic DNA. Data was analyzed using the statistical SPSS package. Results: Our results showed an increased risk of RPL in patients with GG + GC genotype (OR=5.1, 95%CI: 1.04-25.3, p=0.04 in comparison to CC genotype. The frequency of mutant allele G in patients and controls was 0.75 and 0.66 respectively. The mutant allele G predisposes women to miscarriage 1.5 times greater than controls (OR=1.5, 95%CI: 1.03-2.27, p=0.036. The mean number of live births in RPL women (1.3±2.3 was significantly lower compared to control women (4.8±2.3. Conclusion: This study indicated that the promoter polymorphism (-634C/G of the IL-6 gene has likely influence on individual susceptibility to RPL.

    Implication of serotonergic system in suicide and suicide attempts has been discussed for several years. One of the most abundant serotonin receptors in the mammalian brain is the receptor 1A (5-HT1A); studies of its polymorphisms and suicide have provided very inconsistent results so far. The suggestion that the G allele depresses HTR1A autoreceptor expression, and therefore reduces serotonergic neurotransmission that might predispose to depression and suicide, made the promoter polymorphism -1019C>G a very promising candidate gene. In our study we analyzed promoter polymorphism -1019C>G on 323 suicide victims and 190 controls (all of Slovenian origin), taking into account sex, suicide method, and in case of suicide victims also stressful life events. Differences in the distributions of genotype and allele frequencies were not statistically significant between suicide victims and control group, and the same was found for distributions according to sex and suicide method. For 62 suicide victims information about stressful life events in the month prior to the suicide and in childhood was provided. For analysis we combined CG/GG genotypes and compared them to the CC genotype. More stressful life events in the month prior to the suicide were reported for the subgroup with CC genotype (mean number of events = 2.53; SD = 1.50) in comparison to subgroup with CG/GG genotypes (mean number of events = 1.58; SD = 1.32; P suicide victims with CC or CG/GG genotypes did not differ regarding numbers of reported stressful life events in childhood (P > 0.05). Our study provides no evidence for the implication of HTR1A promoter polymorphism in suicide in general, but it suggests further studies that would take into account the interconnected network of suicide completion, genetic background and stress, beside other risk factors.

    Power spectra of human DNA base C+G frequency distribution in all available contiguous sections exhibit the universal inverse power law form of the statistical normal distribution for the 24 chromosomes. Inverse power law form for power spectra of space-time fluctuations is generic to dynamical systems in nature and indicate long-range space-time correlations. A recently developed general systems theory predicts the observed non-local connections as intrinsic to quantumlike chaos governing space-time fluctuations of dynamical systems. The model predicts the following. (1) The quasiperiodic Penrose tiling pattern for the nested coiled structure of the DNA molecule in the chromosome resulting in maximum packing efficiency. (2) The DNA molecule functions as a unified whole fuzzy logic network with ordered two-way signal transmission between the coding and non-coding regions. Recent studies indicate influence of non-coding regions on functions of coding regions in the DNA molecule.

    2004-01-01

    The spatial distribution of DNA base sequence A, C, G and T exhibit selfsimilar fractal fluctuations and the corresponding power spectra follow inverse power law form, which implies the following: (1) A scale invariant eddy continuum, namely, the amplitudes of component eddies are related to each other by a scale factor alone. In general, the scale factor is different for different scale ranges and indicates a multifractal structure for the spatial distribution of DNA base sequence. (2) Long-range spatial correlations of the eddy fluctuations. Multifractal structure to space-time fluctuations and the associated inverse power law form for power spectra is generic to spatially extended dynamical systems in nature and is a signature of self-organized criticality. The exact physical mechanism for the observed self-organized criticality is not yet identified. The author has developed a general systems theory where quantum mechanical laws emerge as self-consistent explanations for the observed long-range space-time...

  17. Verification of C. G. Jung's analysis of Rowland Hazard and the history of Alcoholics Anonymous.

    2006-11-01

    Extant historical scholarship in the Jungian literature and the Alcoholics Anonymous (AA) literature does not provide a complete picture of the treatment of Rowland Hazard by C. G. Jung, an analysis that AA co-founder Bill Wilson claimed was integral to the foundation of AA in theory and practice. Wilson's original report resulted in archivists and historians incorrectly calibrating their searches to the wrong date. The current work definitively solves the mystery of the timing of Hazard's treatment with Jung by placing his preliminary analysis with Jung in the year 1926, rather than 1930 or 1931. Previously unexamined correspondence originating from Jung, Hazard, his cousin Leonard Bacon, his uncle Irving Fisher, and his aunt Margaret Hazard Fisher is supplemented by relevant primary and secondary source material.

    The association between the single nucleotide polymorphisms (SNPs) in -174G/C and -634C/G of interleukin-6 (IL-6) promoter region and prostate cancer was examined in the population of Han people in Hubei region. TaqMan PCR was employed for the gene-typing of -174G/C and -634C/G in promoter region of IL-6 gene to compare the prostate cancer patients and normal controls in terms of genotype frequency, allele frequency and risk of prostate cancer. Enzyme-linked immunosorbent assay (ELISA) was used for the detection of IL-6 concentration in peripheral blood of the patients with prostate cancer and the relationship between the IL-6 level and the genotype was studied.Our results showed that in all the subjects, the genotype of genetic locus -174G/C was found to be GG and no CG and CC were observed. There was a significant difference in gene frequency of GG,CG and CC of-634C/G and allele frequency of G and C between prostate cancer patients and normal controls (P<0.05) and the gene frequency of GG+CG increased with the clinical stages and pathological grades of prostate cancer. The IL-6 level in GG+CG group was significantly higher than that in CC group. It was.concluded that no SNP in-174G/C IL-6 promoter region was found in the population of Han people in Hubei region. The SNP in -634C/G was, to some extent, associated with the development and progression of prostate cancer. The population with GG+CG genetype has higher risk for prostate cancer.

  19. Disruptive collisions as the origin of 67P/C-G and small bilobate comets

    Images of comets sent by spacecraft have shown us that bilobate shapes seem to be common in the cometary population. This has been most recently evidenced by the images of comet 67P/C-G obtained by the ESA Rosetta mission, which show a low-density elongated body interpreted as a contact binary. The origin of such bilobate comets has been thought to be primordial because it requires the slow accretion of two bodies that become the two main components of the final object. However, slow accretion does not only occur during the primordial phase of the Solar System, but also later during the reaccumulation processes immediately following collisional disruptions of larger bodies. We perform numerical simulations of disruptions of large bodies. We demonstrate that during the ensuing gravitational phase, in which the generated fragments interact under their mutual gravity, aggregates with bi-lobed or elongated shapes formed form by reaccumulation at speeds that are at or below the range of those assumed in primordial accretion scenarios [1]. The same scenario has been demonstrated to occur in the asteroid belt to explain the origin of asteroid families [2] and has provided insight into the shapes of thus-far observed asteroids such as 25143 Itokawa [3]. Here we show that it is also a more general outcome that applies to disruption events in the outer Solar System. Moreover, we show that high temperature regions are very localized during the impact process, which solves the problem of the survival of organics and volatiles in the collisional process. The advantage of this scenario for the formation of small bilobate shapes, including 67P/C-G, is that it does not necessitate a primordial origin, as such disruptions can occur at later stages of the Solar System. This demonstrates how such comets can be relatively young, consistent with other studies that show that these shapes are unlikely to be formed early on and survive the entire history of the Solar System [4

    We investigated the interactive effects of BclI C/G (rs41423247) allelic variants and the diagnosis of major depressive disorder (MDD) on hippocampal shape and integrity of the left parahippocampal subdivision of the cingulum. Fifty-two patients with MDD and 52 healthy controls (HCs) underwent T1-weighted structural magnetic resonance imaging and BclI C/G (rs41423247) genotyping. We analyzed hippocampal shape using the FIRST module of FSL and analyzed white matter (WM) integrity using diffusion tensor imaging (DTI) and tract-based spatial statistics (TBSS). Significant alterations in left hippocampal shape and decreased fractional anisotropy (FA) values of the left parahippocampal cingulum were observed in MDD patients, compared to HCs. In addition, MDD patients of the BclI minor (G-) allele carrier group showed significant alterations in left hippocampal shape and decreased FA values of the left parahippocampal cingulum compared to BclI minor (G-) allele carrier HCs. No significant differences between diagnostic subgroups of the C/C homozygotes were observed. Our study provides evidence for alterations in hippocampal shape and decreased integrity of the WM region associated with the hippocampus in MDD, and for the possible influence of BclI C/G polymorphism (rs41423247) on hippocampal shape and integrity of the parahippocampal subdivision of the cingulum in depression.

The aim of this study was to analyze the allele and genotype frequencies of these polymorphisms in PAI-1 gene and its association with metabolic syndrome and its components in a sample of Mexican mestizo children. Methods This study included 100 children with an age range between 6-11 years divided in two groups: a 48 children diagnosed with metabolic syndrome and b 52 children metabolically healthy without any clinical and biochemical alteration. Metabolic syndrome was defined as the presence of three or more of the following criteria: fasting glucose levels ≥ 100 mg/dL, triglycerides ≥ 150 mg/dL, HDL-cholesterol th percentile, systolic blood pressure (SBP and diastolic blood pressure (DBP ≥ 95th percentile and insulin resistance HOMA-IR ≥ 2.4. The -844 G/A and HindIII C/G PAI-1 polymorphisms were analyzed by PCR-RFLP. Results For the -844 G/A polymorphism, the G/A genotype (OR = 2.79; 95% CI, 1.11-7.08; p = 0.015 and the A allele (OR = 2.2; 95% CI, 1.10-4.43; p = 0.015 were associated with metabolic syndrome. The -844 G/A and A/A genotypes were associated with increase in plasma triglycerides levels (OR = 2.6; 95% CI, 1.16 to 6.04; p = 0.02, decrease in plasma HDL-cholesterol levels (OR = 2.4; 95% CI, 1.06 to 5.42; p = 0.03 and obesity (OR = 2.6; 95% CI, 1.17-5.92; p = 0.01. The C/G and G/G genotypes of the HindIII C/G polymorphism contributed to a significant increase in plasma total cholesterol levels (179 vs. 165 mg/dL; p = 0.02 in comparison with C/C genotype. Conclusions The -844 G/A PAI-1 polymorphism is related with the risk of developing metabolic syndrome, obesity and atherogenic dyslipidemia, and the HindIII C/G PAI-1 polymorphism was associated with the

    The activity of glufosfamide (beta-D-glucopyranosyl-N,N'-di-(2-chloroethyl)-phosphoric acid diamide) against pancreatic cancer was investigated in a multicentre, phase II clinical study. Chemotherapy-nai;ve patients with advanced or metastatic disease were treated with glufosfamide (5 g/m(2)) using a 1-h intravenous (i.v.) infusion every 3 weeks. Patients were randomised between active-hydration and normal fluids to evaluate the nephroprotective effect of forced diuresis. Patients experiencing >0.4 mg/dl (>35 micromol/l) increase in serum creatinine compared with their baseline value were taken off treatment for safety reasons. The evaluation of response was according to the Response evaluation criteria in solid tumours (RECIST). Blood sampling was performed for pharmacokinetic analyses. 35 patients from 13 institutions were registered over a 13-month period. A total of 114 treatment cycles (median 3, range 1-8) were administered to 34 patients; 18 patients were allocated to the hydration arm. Overall haematological toxicity was mild. Metabolic acidosis occurred in 2 patients treated in the active-hydration arm, grade 3 hypokalaemia was recorded in 5 patients and grade 3 hypophosphataemia in 4 patients. One patient had a grade 4 increase in serum creatinine level, concomitantly to disease progression. Active-hydration did not show a nephroprotective effect and the plasma pharmacokinetics (Pk) of glufosfamide was not significantly influenced by hydration. Two confirmed partial remissions (PR) were reported (response rate 5.9%, 95% Confidence Interval (CI) 0.7-19.7%) and 11 cases obtained disease stabilisation (32.4%). An extra mural review panel confirmed all of the responses. Median overall survival was 5.3 months (95% CI 3.9-7.1) and time to progression (TTP) was 1.4 months (95% CI 1.3-2.7). In conclusion, glufosfamide administered using a 1-h infusion every 3 weeks has a modest activity in advanced pancreatic adenocarcinoma. Haematological toxicity is

    The activity of glufosfamide (beta-D-glucosylisophosphoramide mustard) was tested in a multicentre phase II clinical trial in patients with advanced non-small cell lung cancer (NSCLC) who had received one prior line of platinum-based chemotherapy. Patients were treated with 5000 mg/m(2) glufosfamide by a 1-h intravenous (i.v.) infusion every 3 weeks following registration at the European Organisation for Research and Treatment of Cancer (EORTC) Data Center. Patients were randomised between hydration and no hydration to evaluate the nephroprotective effects of forced diuresis. Patients experiencing >/= 35 micromol/l increase of serum creatinine compared with baseline values were taken off the treatment. The Response evaluation criteria in solid tumours (RECIST) criteria were applied for the response assessment. Blood sampling was performed for a pharmacokinetic analysis. 39 patients from seven institutions were registered and a median of three cycles was given (range 0-6) cycles; 20 patients were randomised to the hydration arm. Haematological toxicity was mild, but treatment-related metabolic and electrolytic abnormalities and increases of serum creatinine occurred in several patients. Hydration did not have any significant influence on the plasma pharmacokinetics of glufosfamide and did not show any nephroprotective effect. Only one confirmed partial remission was observed (response rate 3%; 95% (Confidence Interval (CI) 0-14) and 18 cases with stable disease (49%) were recorded as assessed by an independent panel. Median survival of all patients treated was 5.8 months (95% CI 4.2-7.9). In conclusion, glufosfamide administered by a 1-h infusion every 3 weeks has modest activity in advanced NSCLC patients after one prior platinum-based chemotherapy.

    An independent Pathology Working Group (PWG) re-evaluated the kidney changes in National Toxicology Program (NTP) toxicology/carcinogenicity studies of tert-butyl alcohol (TBA) in F344/N rats to determine possible mode(s) of action underlying renal tubule tumors in male rats at 2-years. In the 13-week study, the PWG confirmed that the normal pattern of round hyaline droplets in proximal convoluted tubules was replaced by angular droplet accumulation, and identified precursors of granular casts in the outer medulla, changes typical of alpha(2u)-globulin (α(2u)-g) nephropathy. In the 2-year study, the PWG confirmed the NTP observation of increased renal tubule tumors in treated male groups. Linear papillary mineralization, another hallmark of the α(2u)-g pathway was present only in treated male rats. Chronic progressive nephropathy (CPN) was exacerbated in high-dose males and females, with a relationship between advanced grades of CPN and renal tumor occurrence. Hyperplasia of the papilla lining was a component of CPN in both sexes, but there was no pelvic urothelial hyperplasia. High-dose females showed no TBA-related nephrotoxicity. The PWG concluded that both α(2u)-g nephropathy and exacerbated CPN modes of action were operative in TBA renal tumorigenicity in male rats, neither of which has relevance for human cancer risk.

  9. Formation of bi-lobed 67P/C-G-like shapes by sub-catastrophic collisions

    Jutzi, Martin; Benz, Willy

    2016-10-01

    Small bodies with a bi-lobe shape such as comet 67P/C-G have been argued to form as the result of low velocity (v ≈ vesc) collisional mergers of similar-sized bodies very early on in the history of the solar system [1]. However, the recent analysis of the subsequent collisional survival of the global structure and shape of comet 67P/C-G strongly suggests that such a structure will not survive until today [2]. Hence, the comet must have acquired its present characteristics as a result of a collision occurring at later time when the relative velocities between small bodies are much higher (v >> vesc).One possible scenario would be that 67P/C-G-like bi-lobe structures form as the result of collisional disruptions of larger parent bodies [3]. Whether the internal properties of such larger parent bodies, the timing of such a collision, and the subsequent survival of the shape produced is compatible with observations will remain to be seen.Here, we propose a scenario in which the final bi-lobe shapes result from low-energy, sub-catastrophic impacts. We start with bodies of about the same mass as comet 67P/C-G, which are rotating and are slightly elongated (i.e., with properties which are consistent with the outcome of the disruptions of larger bodies). We use a SPH shock physics code to model the impacts, the subsequent re-accumulation of material and the reconfiguration into a stable final shape. Our modelling results suggest that these kind of collisions result in "splitting" events which frequently lead to formation of bi-lobe 67P/C-G-like shapes.The frequency of such small-scale impact events is consistent with a young (less than 1 Gy) age of the shape of comet 67P/C-G [2]. Equally important, the probability for such a shape-forming event to take place without a subsequent shape-destroying event occurring until today is reasonably high.Although the collisions considered in this work can alter the global shape, their respective energy is small enough not to lead to

    A social skills training (SST) for high-functioning children with autism spectrum disorders (ASD) was evaluated in an outpatient setting using a combined between- and within-subject design in which SST and a waiting list condition were compared. According to parents and teachers, the SST produced greater improvement of social skills than the waiting list, and these effects were maintained at 3 months follow-up. No between-group effects were found for loneliness, although in general scores on this outcome measure decreased from pre- to follow-up. The effects of SST were unaffected by social anxiety, ADHD symptoms, Theory of Mind, or desire for social interaction. Altogether, SST seems an effective intervention for high-functioning children with ASD that can be applied in daily clinical practice.

    We give a sufficient condition on a finite -group of nilpotency class 2 so that $\\mathrm{Aut}_c(G)=\\mathrm{Inn}(G)$, where $\\mathrm{Aut}_c(G)$ and $\\mathrm{Inn}(G)$ denote the group of all class preserving automorphisms and inner automorphisms of respectively. Next we prove that if and are two isoclinic finite groups (in the sense of . Hall), then $\\mathrm{Aut}_c(G)≅\\mathrm{Aut}_c(H)$. Finally we study class preserving automorphisms of groups of order $p^5,p$ an odd prime and prove that $\\mathrm{Aut}_c(G)=\\mathrm{Inn}(G)$ for all the groups of order $p^5$ except two isoclinism families.

    Full Text Available Associations between interleukin 6 (IL-6 polymorphisms and Alzheimer's disease (AD remain controversial and ambiguous. The aim of this meta-analysis is to explore more precise estimations for the relationship between IL-6-174 G/C and -572 C/G polymorphisms and risk for AD. Electronic searches for all publications in databases PubMed and EMBASE were conducted on the associations between IL-6 polymorphisms and risk for AD until January 2012. Odds ratio (OR and 95% confidence intervals (CIs were calculated using fixed and random effects models. Twenty-seven studies were included with a total of 19,135 individuals, involving 6,632 AD patients and 12,503 controls. For IL-6-174 G/C polymorphism, the combined results showed significant differences in recessive model (CC vs. CG+GG: OR = 0.65, 95%CI = 0.52-0.82. As regards IL-6-572 C/G polymorphism, significant associations were shown in dominant model (CG+GG vs. CC: OR= 0.73, 95% CI = 0.62-0.86 and in additive model (GG vs. CC, OR= 0.66, 95% CI = 0.46-0.96. In conclusion, genotype CC of IL-6-174 G/C and genotype GG plus GC of IL-6-572 C/G could decrease the risk of AD.

    Full Text Available Abstract Background Both apolipoprotein (Apo C-III gene polymorphism and alcohol consumption have been associated with increased serum triglyceride (TG levels, but their interactions on serum TG levels are not well known. The present study was undertaken to detect the interactions of the ApoC-III 3238C>G (rs5128 polymorphism and alcohol consumption on serum TG levels. Methods A total of 516 unrelated nondrinkers and 514 drinkers aged 15-89 were randomly selected from our previous stratified randomized cluster samples. Genotyping of the ApoC-III 3238C>G was performed by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis, and then confirmed by direct sequencing. Interactions of the ApoC-III 3238C>G genotype and alcohol consumption was assessed by using a cross-product term between genotypes and the aforementioned factor. Results Serum total cholesterol (TC, TG, high-density lipoprotein cholesterol (HDL-C, ApoA-I and ApoB levels were higher in drinkers than in nondrinkers (P P P P P P P P Conclusions This study suggests that the ApoC-III 3238CG heterozygotes benefited more from alcohol consumption than CC and GG homozygotes in increasing serum levels of HDL-C, ApoA-I, and the ratio of ApoA-I to ApoB, and lowering serum levels of TC and TG.

    Suppose G is a non-free finitely generated Kleinian group without parabolics which is not a lattice and let C(G) denote the commensurator in PSL(2,C). We prove that if the limit set of G is not a round circle, then C(G) is discrete. Furthermore, G has finite index in C(G) unless G is a fiber group in which case C(G) is a lattice.

  19. Hyperrecombination in pneumococcus: A/G to C.G repair and requirement for DNA polymerase I.

    Science.gov (United States)

    Pasta, F; Sicard, M A

    1994-09-01

    During pneumococcal transformation, we had previously described that the ami36 mutation, which results from a C.G to A.T transversion, induces a large excess of wild-type recombinants in two point crosses. Upon donor-recipient DNA recombination, two heteroduplexes are generated by this mutation: A36/G+ and C+/T36. In two point crosses, hyperrecombination is observed only when transformation leads to the A/G mismatch. Here, we have studied the separate evolution of A36/G+ and C+/T36 heterozygotes created upon transformation of an ami36 mutant strain with artificial heteroduplex DNAs. We found that the A36/G+ mismatch leads to a preferential generation of wild-type progeny as compared with the complementary C+/T36 mismatch. This result suggests that A/G carrying transformants partly behave as wild-type homozygotes. The only way to account for such behavior is an excision repair correcting some A/G mispairs created upon transformation into C.G pairs. Moreover, we show that hyperrecombination triggered by ami36 is strongly reduced in a DNA polymerase I deficient strain. This strengthens the fact of DNA repair synthesis, which should be therefore prominently due to DNA polymerase I.

  20. Comparison of quality of induction of anaesthesia between intramuscularly administered ketamine, intravenously administered ketamine and intravenously administered propofol in xylazine premedicated cats

    Full Text Available The quality of induction of general anesthesia produced by ketamine and propofol, 2 of the most commonly used anaesthetic agents in cats, was assessed. Eighteen cats admitted for elective procedures were randomly assigned to 3 groups and then premedicated with xylazine 0.75 mg/kg intramuscularly before anaesthesia was induced with ketamine 15 mg/kg intramuscularly (KetIM group, ketamine 10 mg/kg intravenously (KetIV group or propofol 4 mg/kg intravenously (PropIV group. Quality of induction of general anaesthesia was determined by scoring ease of intubation, degree of struggling, and vocalisation during the induction period. The quality of induction of anaesthesia of intramuscularly administered ketamine was inferior to that of intravenously administered ketamine, while intravenously administered propofol showed little difference in quality of induction from ketamine administered by both the intramuscular and intravenous routes. There were no significant differences between groups in the ease of intubation scores, while vocalisation and struggling were more common in cats that received ketamine intramuscularly than in those that received intravenously administered ketamine or propofol for induction of anaesthesia. Laryngospasms occurred in 2 cats that received propofol. The heart rates and respiratory rates decreased after xylazine premedication and either remained the same or decreased further after induction for all 3 groups, but remained within normal acceptable limits. This study indicates that the 3 regimens are associated with acceptable induction characteristics, but administration of ketamine intravenously is superior to its administration intramuscularly and laryngeal desensitisation is recommended to avoid laryngospasms.

    A 5-day-old girl was referred to our clinic for evaluation of congenital malformations. She was identified with a pathogenic mutation c.758C>G (p.Pro253Arg) in FGFR2 gene using targeted exome sequencing. The de novo mutation was confirmed with Sanger sequencing in the patient and her parents. She showed occipital plagiocephaly with frontal bossing (Figure A and B). Skull frontal and lateral radiography revealed fusion of most of the sutures except coronal suture, with convolutional markings (Figure D and E). She had complete cleft palate (Figure C). Her fused bilateral hands showed type II syndactyly with complete syndactyly between the ring and the little fingers (Figure F1-F3). Both toes were simple syndactyly with side-to-side fusion of skin (Figure G1-)

  2. A novel complex A/C/G intergenotypic recombinant of hepatitis B virus isolated in southern China.

    Directory of Open Access Journals (Sweden)

    Heling Su

    Full Text Available Hepatitis B virus (HBV genotypes and subgenotypes may vary in geographical distribution and virological features. Previous investigations, including ours, showed that HBV genotypes B and C were respectively predominant in South and North China, while genotypes A and D were infrequently detected and genotype G was not found. In this study, a novel A/C/G intergenotype was identified in patients with chronic HBV infection in Guilin, a city in southern China. Initial phylogenetic analysis based on the S gene suggested the HBV recombinant to be genotype G. However, extended genotyping based on the entire HBV genome indicated it to be an A/C/G intergenotype with a closer relation to genotype C. Breakpoint analysis using the SIMPLOT program revealed that the recombinant had a recombination with a arrangement of genotypes A, G, A and C fragments. Compared with the HBV recombinants harboring one or two genotype G fragments found in Asian countries, this Guilin recombinant was highly similar to the Vietnam (98-99% and Long An recombinants (96-99%, but had a relatively low similarity to the Thailand one (89%. Unlike those with the typical genotype G of HBV, the patients with the Guilin recombinant were seropositive for HBeAg. Moreover, a relatively high HBV DNA viral load (>2 × 10(6 IU/ml was detected in the patients, and the analysis of viral replication capacity showed that the Guilin recombinant strains had a competent replication capacity similar to genotypes B and C strains. These findings can aid in not only the clarification of the phylogenetic origin of the HBV recombinants with the genotype G fragment found in Asian countries, but also the understanding of the virological properties of these complicated HBV recombinants.

    Following the successful wake-up of the ROSETTA spacecraft on 20 January 2014, the OSIRIS imaging system was fully re-commissioned at the end of March 2014 confirming its initial excellent performances. The OSIRIS instrument includes two cameras: the Narrow Angle Camera (NAC) and the Wide Angle Camera (WAC) with respective fieldsofview of 2.2° and 12°, both equipped with 2K by 2K CCD detectors and dual filter wheels. The NAC filters allow a spectral coverage of 270 to 990 nm tailored to the investigation of the mineralogical composition of the nucleus of comet P/Churyumov- Gerasimenko whereas those of the WAC (245-632 nm) aim at characterizing its coma [1]. The NAC has already secured a set of four complete light curves of the nucleus of 67P/C-G between 3 March and 24 April 2014 with a primary purpose of characterizing its rotational state. A preliminary spin period of 12.4 hours has been obtained, similar to its very first determination from a light curve obtained in 2003 with the Hubble space telescope [2]. The NAC and WAC will be recalibrated in the forthcoming weeks using the same stellar calibrators VEGA and the solar analog 16 Cyg B as for past inflight calibration campaigns in support of the flybys of asteroids Steins and Lutetia. This will allow comparing the pre- and post-hibernation performances of the cameras and correct the quantum efficiency response of the two CCD and the throughput for all channels (i.e., filters) if required. The accurate photometric analysis of the images requires utmost care due to several instrumental problems, the most severe and complex to handle being the presence of optical ghosts which result from multiple reflections on the two filters inserted in the optical beam and on the thick window which protects the CCD detector from cosmic ray impacts. These ghosts prominently appear as either slightly defocused images offset from the primary images or large round or elliptical halos. We will first present results on the global

    GIADA (Grain Impact Analyzer and Dust Accumulator) flying on-board Rosetta is devoted to study the cometary dust environment of 67P/Churiumov-Gerasimenko. GIADA is composed of 3 sub-systems: the GDS (Grain Detection System), based on grain detection through light scattering; an IS (Impact Sensor), giving momentum measurement detecting the impact on a sensed plate connected with 5 piezoelectric sensors; the MBS (MicroBalances System), constituted of 5 Quartz Crystal Microbalances (QCMs), giving cumulative deposited dust mass by measuring the variations of the sensors' frequency. The combination of the measurements performed by these 3 subsystems provides: the number, the mass, the momentum and the velocity distribution of dust grains emitted from the cometary nucleus.No prior in situ dust dynamical measurements at these close distances from the nucleus and starting from such large heliocentric distances are available up to date. We present here the first results obtained from the beginning of the Rosetta scientific phase. We will report dust grains early detection at about 800 km from the nucleus in August 2014 and the following measurements that allowed us characterizing the 67P/C-G dust environment at distances less than 100 km from the nucleus and single grains dynamical properties.

    The scientific objective of the Comet Nucleus Sounding Experiment by Radiowave Transmission (CONSERT) aboard ESA spacecraft Rosetta is to perform a dielectric characterization of comet 67P/Chuyurmov-Gerasimenko's nucleus. This is done by means of a bi-static sounding between the lander Philae launched onto the comet's surface and the orbiter Rosetta. For the sounding, the CONSERT unit aboard the lander will receive and process the radio signal emitted by the orbiter counterpart of the instrument. It will then retransmit a signal back to the orbiter to be received by CONSERT. This happens at the milliseconds time scale. During the descent of lander Philae onto the comet's surface, CONSERT was operated as a bi-static RADAR. A single measurement of the obtained data is composed of the dominant signal from the direct line-of-sight propagation path between lander and orbiter as well as paths from the lander's signal being reflected by the comet's surface. From peak power measurements of the dominant direct path during the descent, the knowledge of the orbiter and lander positions and simulations of CONSERT's orbiter and lander antenna characteristics as well as polarization properties, we were able to reconstruct the lander's attitude and estimate the spin rate of the lander along the descent trajectory. Additionally, certain operations and manoeuvres of orbiter and lander, e.g. the deployment of the lander legs and CONSERT antennas or the orbiter change of attitude in order to orient the science towards the assumed lander position, are also visible in the data. The information gained on the landers attitude is used in the reconstruction of the dielectric properties of 67P/C-G's surface and near subsurface (metric to decametric scale) and will hopefully prove helpful supporting the data interpretation of other instruments. In the CONSERT measurements, the comet's surface is visible during roughly the last third of the descent enabling a mean permittivity estimation of

    2014-01-01

    There are a plethora of concept inventories in physics available for faculty to use, but it is not always clear exactly why you would use these tests, or how you should administer them and interpret the results. These multiple-choice research-based tests about physics concepts are valuable because they allow for standardized comparisons among institutions, instructors, or over time. In order for these comparisons to be meaningful, you should use best practices for administering the tests. Here we discuss best practices for administering concept inventories including background on these types of tests and specifics of how to give them online or in-class. We also discuss advantages and disadvantages of different incentives you could give your students, interpretation of scores and common concerns you may have about using concept inventories.

    Objective Family and twin studies have suggested genetic liability for panic disorder (PD) and therefore we sought to determine the role of noradrenergic and serotonergic candidate genes for susceptibility for PD in a Japanese population. Methods In this age- and gender-matched case-control study involving 119 PD patients and 119 healthy controls, we examined the genotype distributions and allele frequencies of the serotonin transporter gene linked polymorphic region (5-HTTLPR), −1019C/G (rs6295) promoter polymorphism of the serotonin receptor 1A (5-HT1A), and catechol-O-methyltransferase (COMT) gene polymorphism (rs4680) and their association with PD. Results No significant differences were evident in the allele frequencies or genotype distributions of the COMT (rs4680), 5-HTTLPR polymorphisms or the −1019C/G (rs6295) promoter polymorphism of 5-HT1A between PD patients and controls. Although there were no significant associations of these polymorphisms with in subgroups of PD patients differentiated by gender or in subgroup comorbid with agoraphobia (AP), significant difference was observed in genotype distributions of the −1019C/G (rs6295) promoter polymorphism of 5-HT1A between PD patients without AP and controls (p=0.047). Conclusion In this association study, the 1019C/G (rs6295) promoter polymorphism of the 5-HT1A receptor G/G genotype was associated with PD without AP in a Japanese population. PMID:28096880

    The aim of this study was to explain the variability of CYP2D6 activity by the identification of CYP2D6 deletion and multiplications, and the single-nucleotide polymorphisms (SNPs) -1584C-->G, 31G-->A and 2988G-->A in Mexican Mestizo and Tepehuano subjects. One hundred twelve Mestizos and 99 Tepehuano Amerindians were studied, who were previously phenotyped with dextromethorphan. The frequencies of CYP2D6*2A [-1584C-->G] and *35 [-1584C-->G, 31G-->A] were 10.7 and 4.1%, respectively, in Mestizos, which is evidently a trend towards an extensive metabolism in carriers of the -1584G change. In Tepehuanos, *2A was identified with a frequency of 20%, and the allele *35 was not found. The frequencies of CYP2D6*5 (deletion) and *41[2988G-->A] were 1.3 and 2.2% in Mestizos and 0.5 and 1% in Tepehuanos, respectively. The SNP 2988A was found to be significantly related with the intermediate metabolizer phenotype in Mestizos (R = 0.309; n = 88; p = 0.006). The multiplications had frequencies of 4.1% in Mestizos and 1.5% in Tepehuanos. Only in the Mestizos did the presence of multiplications significantly decrease the DM/DX (dextromethorphan/dextrorphan) values (R = 0.273; n = 88; p = 0.016). The polymorphisms studied had different frequencies between Tepehuanos and Mestizos (p < 0.001); however, in the Tepehuano group these had a low influence on their phenotypic expression. It helps to understand the genotype-phenotype relationships of CYP2D6 in our studied populations.

    Background It has been recently reported that inflammatory mechanisms play an important role in in-stent restenosis (ISR) processes.Inflammatory factors after percutaneous coronary intervention (PCI) for dynamic monitoring can probably predict ISR.Functional polymorphisms in the promoter region of genes coding for inflammatory factors might be important for determining the magnitude of the inflammatory response.Thus,in the present study,we aimed to investigate the serial changes in serum interleukin-6 (IL-6) levels before and after PCI and the relationship between the -572C/G polymorphism in the promoter region of the IL-6 gene and ISR.We also discussed genetic polymorphisms in the inflammatory response to PCI.Methods A total of 437 patients who successfully underwent bare metal stent (BMS) implantation with a follow-up angiography were divided into an ISR group (n=166) and a non-ISR (NISR) group (n=271).The IL-6 gene promoter polymorphism at position-572 was determined by restricted fragment length polymorphism using the polymerase chain reaction (PCR-RFLP) method.The serum IL-6 levels before and one day,five days and 180 days after PCI were determined by the radioimmunoassay method.Results ISR patients showed higher IL-6 serum levels than NISR patients before PCI ((324.42±28.14) ng/L vs.(283.22±47.30) ng/L,P<0.001),and one day post-PCI IL-6 serum levels in the ISR group also showed a significantly higher level than in the NISR group (P <0.001).Increased IL-6 after PCI persisted at a statistically significant level throughout the study in ISR patients,whereas IL-6 levels had normalized five days after the procedure in NISR patients.One day post-PCI serum IL-6 level was the most accurate marker for diagnosis of ISR,the area under the ROC curve being 0.927 (95% C/0.878-0.977).The cut-off value for IL-6 to predict ISR was over 355.50 ng/L,with a sensitivity of 0.968 and a specificity of 0.865.There were no significant differences in frequencies of-572

    The DNA adduction by the environmental carcinogen 7H-dibenzo[c,g]carbazole (DBC) and chemically synthesized 2-OH, 3-OH, and 4-OH metabolites of DBC was investigated in liver and skin of female CD-1 mice. After topical application to the skin of 37 mumol/kg of DBC or the phenolic metabolites, DNA adducts were measured by a 32P-post-labeling assay employing carrier-free [gamma-32P]ATP and ATP-deficient conditions. In liver, DBC produced four major and several minor chromatographically distinct adducts of as yet undetermined chemical structure. The adduct pattern elicited by 3-OH-DBC was qualitatively similar to the DBC adduct pattern, while this was not the case for 2-OH-DBC and 4-OH-DBC. On the basis of co-chromatography experiments under various conditions, the DBC and 3-OH-DBC adducts appeared identical, and the total of adduction elicited by these compounds in liver was substantial. Similar results were observed when DBC or 3-OH-DBC were administered i.p. As a major difference between the two compounds, one 3-OH-DBC adduct (no. 3) was 4.4- and 7.0-fold lower than the corresponding DBC adduct after i.p. and topical dosing, respectively. In skin, DBC produced two major adduct fractions after topical application, one of which could be chromatographically resolved into three subcomponents. Prominent adducts produced in skin DNA by each of the three metabolites were different from those elicited by DBC, and the level of adduction by the metabolites was significantly lower than that by DBC. Comparison of the skin and liver DBC-DNA adduct patterns after topical application of DBC showed that only one of the four major chromatographically resolved skin adducts corresponded to a major liver adduct (no. 3), and that total adduction in liver was 13.5-fold higher than in skin. These results suggested that activation of DBC to DNA-binding compounds in liver occurs through at least two pathways with 3-OH-DBC being a proximate carcinogen involved in the formation of most of the

    Nasal polyps are strongly associated with a risk of chronic rhinosinusitis development as well as other obstruction including asthma and allergy. The following study tested the association of the 140A/G polymorphism of lactoferine (LF) encoding gene and the -33C/G polymorphism of osteoblast-specific factor-2 (OSF-2) encoding gene with a risk of chronic rhinosinusitis with nasal polyps in a Polish population. One hundred ninety five patients of chronic rhinosinusitis with nasal polyps as well as 200 sex, age and ethnicity matched control subjects without chronic sinusitis and nasal polyps were enrolled in this study. Among the group of patients 63 subjects were diagnosed with allergy and 65 subjects with asthma, respectively. DNA was isolated from peripheral blood lymphocytes of patients as well as controls and gene polymorphisms were analyzed by restriction fragments length polymorphism polymerase chain reaction (RFLP-PCR). We reported that the 140A/G LF (OR 4.78; 95% CI 3.07-7.24), the -33C/G OSF-2 OR 3.48; 95% CI 2.19-5.52) and the -33G/G OSF-2 (OR 16.45; 95% CI 6.71-40.30) genotypes were associated with an increased risk of chronic rhinosinusitis with nasal polyps among analyzed group of patients. Moreover, the group of patients without allergy or asthma indicated the association of the -33C/G (OR 3.72; 95% CI 2.24-6.19 and OR 15.11; 95% CI 5.91-38.6) and -33G/G (OR 3.73; 95% CI 2.24-6.19 and OR 14.07; 95% CI 5.47-36.16) genotypes of the OSF-2 as wells as 140A/G (OR 3.89; 95% CI 2.40-6.31 and OR 3.62; 95% CI 2.45-5.34) genotype of OSF-2 with an increased risk of chronic rhinosinusitis with nasal polyps. Finally, it was also found that the selected group of patients with allergy or asthma indicated a very strong association of the -33C/G (OR 2.40; 95% CI 1.23-4.69 and OR 2.40; 95% CI 1.23-4.69, respectively) and -33G/G (OR 16.01; 95% CI 5.77-44.41 and OR 17.90; 95% CI 6.53-49.05, respectively) genotypes of the OSF-2 as wells as 140A/G (OR 3.22; 95% CI 1

    The total cost of administering calcium polycarbophil per unit dose (two tablets) was compared with that of administering psyllium mucilloid (one packet dissolved in 8 oz of water) in 20 elderly nursing-home residents. Times for printing labels, checking and initialing labels, gathering materials needed, and preparing and administering the medications were recorded during at least 50 observations in each treatment group. Total cost included nurses' and pharmacists' time, materials, and medications. Calcium polycarbophil doses were prepared and administered more quickly (mean, 49.5 sec) than psyllium mucilloid (105.3 sec). The mean cost of preparing and administering a unit dose was 28.2 for calcium polycarbophil tablets and 59.9 for psyllium mucilloid. The results suggest that the use of calcium polycarbophil tablets would save time and money in institutions in which laxatives are frequently administered.

Methods: Ninety - six pregnant women with preeclampsia ( including 52 pregnant women with mild preeclampsia and 44 pregnant women with severe preedampsia) and 110 normal pregnant women who received prenatal examination and gave birth to their babies in the hospital and Zhengzhou maternal and child health hospital were selected as research objects, then PCR — RFLP was used to detect genotypes of Survivin gene - 31C/G polymorphism. Results: The frequency of G allele in preeclampsia group was statistically significantly higher than that in control group (P < 0. 05 ) ; and the frequency of G allele in severe preeclampsia group was statistically significantly higher than that in mild preeclampsia group ( P < 0. 05) . Conclusion: G allele of Survivin gene - 31 C/G polymorphism may be one of genetic risk factors of preeclampsia for Chinese women in central China and it may also be associated with ils degree of severity.

    Chronic rhinosinusitis with nasal polyps is strongly associated with other diseases, including asthma and allergy. The following study tested the association of the -765 G/C polymorphism of cyclooxygenase-2 (COX-2) encoding gene and the -14C/G polymorphism of protooncogen MET (MET) encoding gene with a risk of chronic rhinosinusitis with nasal polyps in a Polish population. One hundred ninety-five patients of chronic rhinosinusitis with nasal polyps as well as 200 sex-, age-, and ethnicity-matched control subjects without chronic sinusitis and nasal polyps were enrolled in this study. Among the group of patients, 63 subjects were diagnosed with allergy and 65 subjects with asthma, respectively. DNA was isolated from peripheral blood lymphocytes of patients as well as controls, and gene polymorphisms were analyzed by restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR). Ten percent of the samples have been confirmed by a second method single-strand conformation polymorphism (SSCP)-PCR. We reported that the -765 G/C COX-2 (odds ratio [OR] 7.79; 95% confidence interval [CI] 4.88-12.4, prhinosinusitis with nasal polyps among analyzed group of patients. Moreover, the group of patients without allergy or asthma indicated the association of the -765 C/G (OR 7.25; 95% CI 4.38-12.1, prhinosinusitis with nasal polyps. Finally, it was also found that the selected group of patients with allergy or asthma indicated a very strong association of the -765 G/C (OR 5.64; 95% CI 2.91-10.9 and OR 4.74; 95% CI 2.49-9.03, prhinosinusitis with nasal polyps. Thus, our results suggest that COX-2 and MET gene polymorphisms may have deep impact on the risk of rhinosinusitis nasal polyp formation, which may also depend on asthma or allergy. Our results showed that the -765 G/C polymorphism of COX-2 gene and the -14C/G polymorphism of the MET gene may be associated with the risk of chronic rhinosinusitis with nasal polyps in a Polish population.

    Objective: To investigate the genotype-phenotype correlation in Chinese familial hypertrophic cardiomyopathy (HCM )focusing on the cardiac troponin C gene TNNC1 c. G175C mutation. Methods: All family members of a Chinese pedigree with hypertrophic cardiomyopathy admitted in Third People's Hospital of Qingdao in February 2005 and 200 healthy volunteers were included in this study. The coding exons of 30 hypertrophic cardiomyopathy associated genes were identified by whole exons amplification and high-throughput sequencing in the proband, and the identified mutation were further detected through bi-directional Sanger sequencing in all family members and 200 healthy volunteers. Pedigree analysis included clinical manifestation, physical examination, ECG and echocardiogram. Results: A missense mutation c. G175C was identified in the TNNC1 gene in 2 family members, which resulted in a glutamic acid (E) to glutamine (Q) exchange at amino acid residue 59. A mutation c. A1319G was identified in the MYLK2 gene in 1 family member, which resulted in a lysine (K) to arginine (R) exchange at amino acid residue 440. These mutations were absent in 200 healthy controls. The proband carried the two kinds of mutations and expressed various clinical manifestations of heart failure and had history of ventricular tachycardia, paraxial atrial fibrillation, pacemaker implantation, electrocardiogram showed right bundle branch block and echocardiography examination evidenced thickened interventricular septum (23.3 mm) and apex and reduced wall motion of these segments. The daughter of the proband carried the TNNC1 c. G175C mutation and was also diagnosed with asymptomatic HCM by echocardiography with thickened interventricular septum (19 mm) and apex (15 mm). Conclusion: The novel missense mutation of TNNC1 c. G175C might be the disease-causing gene mutation in this Chinese pedigree with familiar HCM.

    Let G be a finitely generated discrete group. The standard spectral triple on the group C*-algebra C*(G) is shown to admit the quantum group of orientation preserving isometries. This leads to new examples of compact quantum groups. In particular the quantum isometry group of the C*-algebra of the free group on n-generators is computed and shown to be a quantum group extension of the quantum permutation group A_{2n} of Wang. The quantum groups of orientation and real structure preserving isometries are also considered and construction of the Laplacian for the standard spectral triple on C*(G) discussed.

    2016-01-01

    There is an active debate about whether the properties of comets as observed today are primordial or, alternatively, if they are a result of collisional evolution or other processes. We investigate the effects of collisions on a comet with a structure like 67P/C-G. We develop scaling laws for the critical specific impact energies required for a significant shape alteration. These are then used in simulations of the combined dynamical and collisional evolution of comets in order to study the survival probability of a primordially formed object with a shape like 67P/C-G. The effects of impacts on comet 67P/C-G are studied using a SPH shock physics code. The resulting critical specific impact energy defines a minimal projectile size which is used to compute the number of shape-changing collisions in a set of dynamical simulations. These simulations follow the dispersion of the trans-Neptunian disk during the giant planet instability, the formation of a scattered disk, and produce 87 objects that penetrate into t...

    2016-01-01

    The origin of the particular shape of a small body like comet 67P/Churyumov-Gerasimenko (67P/C-G) is a topic of active research. How and when it acquired its peculiar characteristics has distinct implications on the origin of the solar system and its dynamics. We investigate how shapes like the one of comet 67P/C-G can result from a new type of low-energy, sub-catastrophic impacts involving elongated, rotating bodies. We focus on parameters potentially leading to bi-lobed structures. We also estimate the probability for such structures to survive subsequent impacts. We use a smooth particle hydrodynamics (SPH) shock physics code to model the impacts, the subsequent reaccumulation of material and the reconfiguration into a stable final shape. The energy increase as well as the degree of compaction of the resulting bodies are tracked in the simulations. Our modelling results suggest that the formation of bi-lobed structures like 67P/C-G is a natural outcome of the low energy, sub-catastrophic collisions conside...

    Full Text Available The present study examined the cardioprotective role of methanol extract of the edible mushroom Volvariella volvacea against oxidative stress in hyperglycemic rats. Rats divided into 6 groups were administered with nicotinamide and streptozotocin intraperitoneally, except Group I (control. Group II served as diabetic control. Group III was given glibenclamide. Two groups (IV and V of rats received (200 and 400 mg/kg mushroom extracts orally for 30 days and Group VI received vitamin E (40 mg/kg. After the treatment period, lipid peroxides, carbonyl end products, advanced glycation end products, reduced glutathione, glutathione peroxidase, glutathione-S transferase, catalase, superoxide dismutase and non-enzymatic anti-oxidants (vitamin C and E were assessed in the heart tissues of experimental animals. Glycosylated hemoglobin was estimated in blood. Electrocardiography recordings of the treated groups were also done. The results showed that mushroom extract treatment reduced the lipid peroxides, advanced glycation end products and protein carbonyls significantly and reversed the altered anti-oxidant enzymes, and the vitamins.

    The radiation dose to the spine, spinal cord, marrow, and other organs of the body from intrathecal administration of several radiopharmaceuticals was studied. Anatomic models were developed for the spine, spinal cerebrospinal fluid (CSF), spinal cord, spinal skeleton, cranial skeleton, and cranial CSF. A kinetic model for the transport of CSF was used to determine residence times in the CSF; material leaving the CSF was thereafter assumed to enter the bloodstream and follow the kinetics of the radiopharmaceutical as if intravenously administered. The radiation transport codes MCNP and ALGAMP were used to model the electron and photon transport and energy deposition. The dosimetry of Tc-99m DTPA and HSA, In-111 DTPA, I-131 HSA, and Yb-169 DTPA was studied. Radiation dose profiles for the spinal cord and marrow in the spine were developed and average doses to all other organs were estimated, including dose distributions within the bone and marrow.

  13. Tumour targeting with systemically administered bacteria.

    LENUS (Irish Health Repository)

    Morrissey, David

    2012-01-31

    Challenges for oncology practitioners and researchers include specific treatment and detection of tumours. The ideal anti-cancer therapy would selectively eradicate tumour cells, whilst minimising side effects to normal tissue. Bacteria have emerged as biological gene vectors with natural tumour specificity, capable of homing to tumours and replicating locally to high levels when systemically administered. This property enables targeting of both the primary tumour and secondary metastases. In the case of invasive pathogenic species, this targeting strategy can be used to deliver genes intracellularly for tumour cell expression, while non-invasive species transformed with plasmids suitable for bacterial expression of heterologous genes can secrete therapeutic proteins locally within the tumour environment (cell therapy approach). Many bacterial genera have been demonstrated to localise to and replicate to high levels within tumour tissue when intravenously (IV) administered in rodent models and reporter gene tagging of bacteria has permitted real-time visualisation of this phenomenon. Live imaging of tumour colonising bacteria also presents diagnostic potential for this approach. The nature of tumour selective bacterial colonisation appears to be tumour origin- and bacterial species- independent. While originally a correlation was drawn between anaerobic bacterial colonisation and the hypoxic nature of solid tumours, it is recently becoming apparent that other elements of the unique microenvironment within solid tumours, including aberrant neovasculature and local immune suppression, may be responsible. Here, we consider the pre-clinical data supporting the use of bacteria as a tumour-targeting tool, recent advances in the area, and future work required to develop it into a beneficial clinical tool.

    We studied a family presenting 10 individuals affected by autosomal dominant deafness in all frequencies and three individuals affected by high frequency hearing loss. Genomic scanning using the 50k Affymetrix microarray technology yielded a Lod Score of 2.1 in chromosome 14 and a Lod Score of 1.9 in chromosome 22. Mapping refinement using microsatellites placed the chromosome 14 candidate region between markers D14S288 and D14S276 (8.85 cM) and the chromosome 22 near marker D22S283. Exome sequencing identified two candidate variants to explain hearing loss in chromosome 14 [PTGDR – c.G894A:p.R298R and PTGER2 – c.T247G:p.C83G], and one in chromosome 22 [MYH9, c.G2114A:p.R705H]. Pedigree segregation analysis allowed exclusion of the PTGDR and PTGER2 variants as the cause of deafness. However, the MYH9 variant segregated with the phenotype in all affected members, except the three individuals with different phenotype. This gene has been previously described as mutated in autosomal dominant hereditary hearing loss and corresponds to DFNA17. The mutation identified in our study is the same described in the prior report. Thus, although linkage studies suggested a candidate gene in chromosome 14, we concluded that the mutation in chromosome 22 better explains the hearing loss phenotype in the Brazilian family.

    Evidence has been obtained showing that endoplasmic reticulum (ER) stress is closely associated with the development of type 2 diabetes (T2D) and that the human X box binding protein 1 (XBP1) is an important transcription factor involved in the development of ER stress. The study aimed to analyze the potential association between polymorphism -116C/G of XBP1 and the risk of T2D. The association between XBP1 polymorphism -116C/G and T2D risk was assessed among 1058 consecutive unrelated subjects, including 523 T2D patients and 535 healthy controls, in a case control study. The -116GG genotype and -116G allele were more frequent in T2D subjects compared with control subjects by statistical analysis, showing that the -116GG homozygote polymorphism of XBP1 might lead to increased susceptibility to T2D in a Chinese Han population. T2D subjects with the -116GG genotype had higher fasting plasma glucose levels, fasting insulin levels, and HbA1c and worse HOMA-IR than the T2D subjects with -116CG and -116CC genotypes (PG polymorphism of the XBP1 promoter in the pathogenesis of T2D in a Chinese Han population, and more studies are needed to further evaluate our results.

    Most common inherited form of intellectual disability, fragile X syndrome is associated to an expansion of greater than 200 CGG repeats in the 5' untranslated region of the FMR1 gene on the X chromosome which causes transcriptional silencing and deficiency of the encoded protein FMRP. Molecular diagnosis is performed through a combination of PCR to identify fewer than 100-150 repeats and of Southern blot analysis to identify longer alleles and the methylation status of the FMR1 promoter. We present a family with one patient with mild mental retardation who showed an atypical profile at Southern analysis due to the -413C > G transversion located in the FMR1 promoter which had been described as possibly associated with mental retardation. We demonstrated this variant in other four family members along three generations, including the maternal grandfather who did not manifest any pathological feature. Though the -413C > G substitution was not found in a large control series, these findings allowed to exclude its role in determining the disease phenotype.

  17. THE EXCLUSION OF ILEGALLY ADMINISTERED EVIDENCE

    Full Text Available Both judicial practice and specialized texts have brought up the problem of what the punishment for breaking the legal provisions in the activity of evidence administration is, if a matter of fact had been presented by means that are not legally specified or if a piece of evidence was administered by means that are legally specified, but with the violation of legal provisions. Romania has adhered to the most important international juridical instruments adopted in the sphere of human rights by the adoption, modification or completion of internal legislation. As such, for the first time in Romanian criminal procedural legislation, a sanction for the exclusion of evidence has been introduced, as a corollary for the principle of legality and of loyalty in administering evidence. The New Criminal Procedure Code provides the sanction of exclusion as well, but this time the legislator didn’t resume his or herself to a mere conceptual regulation of the sanction, providing both a specific invalidation procedure as well as procedural solutions. In the New Criminal Procedure Code it is shown that in the sphere of evidence-showing a set of rules has been introduced that establishes the principle of loyalty in the obtainment of evidence. These rules, that provide the sanction of excluding evidence obtained through illegal or unloyal means, will determined the growth of professionalism in the ranks of the judiciary bodies on the subject of obtaining evidence and, on the other hand, will guarantee the firm upholding of the parties rights to a fair trial. “Truth, like all other good things, may be loved unwisely – may be pursued too keenly – may cost too much…” Lord Justice Sir James Lewis Knight-Bruce ”It is a deeply ingrained value in our democratic system that the ends do not justify the means.

    The effect of lactoperoxidase (LPO) on dextran sulfate sodium-induced colitis was examined in mice. After 9 d of colitis induction, weight loss, colon shortening, and the histological score were significantly suppressed in mice orally administered LPO (62.5 mg/body/d) as compared to a group administered bovine serum albumin. These results suggest that LPO exhibits anti-inflammatory effects in the gastrointestinal tract.

  19. Functional exploration of the adult ovarian granulosa cell tumor-associated somatic FOXL2 mutation p.Cys134Trp (c.402C>G.

    Directory of Open Access Journals (Sweden)

    Bérénice A Benayoun

    Full Text Available BACKGROUND: The somatic mutation in the FOXL2 gene c.402C>G (p.Cys134Trp has recently been identified in the vast majority of adult ovarian granulosa cell tumors (OGCTs studied. In addition, this mutation seems to be specific to adult OGCTs and is likely to be a driver of malignant transformation. However, its pathogenic mechanisms remain elusive. METHODOLOGY/PRINCIPAL FINDINGS: We have sequenced the FOXL2 open reading frame in a panel of tumor cell lines (NCI-60, colorectal carcinoma cell lines, JEG-3, and KGN cells. We found the FOXL2 c.402C>G mutation in the adult OGCT-derived KGN cell line. All other cell lines analyzed were negative for the mutation. In order to gain insights into the pathogenic mechanism of the p.Cys134Trp mutation, the subcellular localization and mobility of the mutant protein were studied and found to be no different from those of the wild type (WT. Furthermore, its transactivation ability was in most cases similar to that of the WT protein, including in conditions of oxidative stress. A notable exception was an artificial promoter known to be coregulated by FOXL2 and Smad3, suggesting a potential modification of their interaction. We generated a 3D structural model of the p.Cys134Trp variant and our analysis suggests that homodimer formation might also be disturbed by the mutation. CONCLUSIONS/SIGNIFICANCE: Here, we confirm the specificity of the FOXL2 c.402C>G mutation in adult OGCTs and begin the exploration of its molecular significance. This is the first study demonstrating that the p.Cys134Trp mutant does not have a strong impact on FOXL2 localization, solubility, and transactivation abilities on a panel of proven target promoters, behaving neither as a dominant-negative nor as a loss-of-function mutation. Further studies are required to understand the specific molecular effects of this outstanding FOXL2 mutation.

    This study aimed to assess the administered dose based on portal imaging in craniospinal pediatric irradiation by evaluating cases in which portal images did or did not account for the total administered dose. We also intended to calculate the mean increase in total administered dose. Data were collected from General University Hospital Gregorio Marañón; we evaluated the total dose administered, total dose planned, number of portal images per treatment and corresponding monitor units of two different groups: one in which the dose from portal images is deducted from the total administered dose (D), and another in which it was not (N). We used descriptive statistics to analyze the collected data, including the mean and respective standard deviation. We used the Shapiro-Wilk and Spearman rank correlation coefficient tests and estimated the linear regression coefficients. Patients in group D received a mean dose of 29.00 ± 10.28 cGy based on the verification portal images, a quantity that was deducted from the planned dose to match the total administered dose. Patients in group N received a mean dose of 41.50 ± 30.53 cGy, which was not deducted from the planned dose, evidencing a mean increase of 41.50 ± 30.55 cGy over the total administered dose. The acquisition of the set-up verification portal images, without their inclusion in the total administered dose, reflects an average increase in total dose for craniospinal irradiation of pediatric patients. Subtraction of the monitor units used to acquire the verification images is recommended.

  1. Association between the HTR2C rs1414334 C/G gene polymorphism and the development of the metabolic syndrome in patients treated with atypical antipsychotics

    Full Text Available Few studies have assessed the association between the rs1414334 C/G polymorphism in the HTR2C gene and the development of the metabolic syndrome in patients treated with atypical antipsychotics. To provide further evidence, a cross-sectional study was conducted in Spain between 2012 and 2013 in 166 patients with these characteristics. In these patients, the association between the polymorphism and the presence of the metabolic syndrome was determined by implementing binary logistic regression models adjusted for variables associated with the metabolic syndrome. We did not confirm previous claims that the C allele of the polymorphism was linked to the metabolic syndrome: the association was in the opposite direction and non-significant. This conclusion held after taking gender and lifestyle variables into account.

    This article presents the history of one until now unknown case of C.G. Jung: Maggy Reichstein. Born in Indonesia in 1894 in a very aristocratic family, she brought her sister to Zurich to be treated by Jung in 1919, and later she herself was in analysis with him. Jung used her case as example in his lecture in 1937 on the realities of practical psychotherapy, relating it to the process of transference and countertransference. Jung deepened his studies in Eastern psychology after a series of dreams she had, which culminated in the Yoga Kundalini Seminars. She was also the case presented in his article of 1951 on the concept of synchronicity. Jung wrote that her case, concerning synchronicity, remained unique in his experience. Jung also published some of her mandalas. He considered her able to understand his ideas in depth. Reichstein was for Jung an important case, which challenged and triggered his interests in different subjects.

    In this paper, we report the first in-situ detection of the ammonium ion NH_4+ at 67P/Churyumov-Gerasimenko (67P/C-G) in a cometary coma, using the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) / Double Focusing Mass Spectrometer (DFMS). Unlike neutral and ion spectrometers onboard previous cometary missions, the ROSINA/DFMS spectrometer, when operated in ion mode, offers the capability to distinguish NH_4+ from H2O+ in a cometary coma. We present here the ion data analysis of mass-to-charge ratios 18 and 19 at high spectral resolution and compare the results with an ionospheric model to put the these results into context. The model confirms that the ammonium ion NH_4+ is one of the most abundant ion species, as predicted, in the coma near perihelion.

    George Hogenson's 2001 paper 'The Baldwin Effect: a neglected influence on C.G. Jung's evolutionary thinking' developed the radical argument that, if archetypes are emergent, they 'do not exist in the sense that there is no place that the archetypes can be said to be'. In this paper, I show how Hogenson's thinking has been seminal to my own: it is not just archetypes but the mind itself that has no 'place'. The mind is a dynamic system, emergent from the cultural environment of symbolic meanings to which humans are evolutionarily adapted. Drawing on the work of philosopher John Searle, I argue that symbols constitute the realities that they bring forth, including the imaginal realities of the psyche. The implications for clinical work include a rejection of structural models of the psyche in favour of the emergence of symbolic realities in the context of psychoanalysis as a distributed system of cognition. © 2015, The Society of Analytical Psychology.

    Full Text Available Background Sedation in dentistry is a controversial topic given the variety of opinions regarding its safe practice. Aims This article evaluates the various techniques used to administer sedation in dentistry and specific methods practiced to form a recommendation for clinicians. Methods An extensive literature search was performed using PubMed, Medline, Google Scholar, Google, and local library resources. Results Most of the literature revealed a consensus that light sedation on low-risk American Society of Anesthesiologists (ASA groups, that is ASA I, and possibly II, is the safest method for sedation in a dental outpatient setting. Conclusion Formal training is essential to achieve the safe practice of sedation in dentistry or medicine. The appropriate setting for sedation should be determined as there is an increased risk outside the hospital setting. Patients should be adequately assessed and medication titrated appropriately, based on individual requirements.

    Defects in the respiratory chain or mitochondrial ATP synthase (complex V) result in mitochondrial dysfunction that is an important cause of inherited neurological disease. Two of the subunits of complex V are encoded by MT-ATP6 and MT-ATP8 in the mitochondrial genome. Pathogenic mutations in MT-ATP6 are associated with the Leigh syndrome, the syndrome of neuropathy, ataxia, and retinitis pigmentosa (NARP), as well as with non-classical phenotypes, while MT-ATP8 is less frequently mutated in patients with mitochondrial disease. We investigated two adult siblings presenting with features of cerebellar ataxia, peripheral neuropathy, diabetes mellitus, sensorineural hearing impairment, and hypergonadotropic hypogonadism. As the phenotype was suggestive of mitochondrial disease, mitochondrial DNA was sequenced and a novel heteroplasmic mutation m.8561C>G in the overlapping region of the MT-ATP6 and MT-ATP8 was found. The mutation changed amino acids in both subunits. Mutation heteroplasmy correlated with the disease phenotype in five family members. An additional assembly intermediate of complex V and increased amount of subcomplex F1 were observed in myoblasts of the two patients, but the total amount of complex V was unaffected. Furthermore, intracellular ATP concentration was lower in patient myoblasts indicating defective energy production. We suggest that the m.8561C>G mutation in MT-ATP6/8 is pathogenic, leads biochemically to impaired assembly and decreased ATP production of complex V, and results clinically in a phenotype with the core features of cerebellar ataxia, peripheral neuropathy, diabetes mellitus, and hypergonadotropic hypogonadism.

    We aimed to investigate two main polymorphisms in the 3' untranslated region (3'UTR) of the HLA-G gene [14bp insertion/deletion (INS/DEL) and +3142 C>G] and to assess their impact on the soluble HLA-G (sHLA-G) production in patients with multiple sclerosis (MS). This study included 60 patients with relasping-remitting (RR) MS and 112 healthy donors (HD). Mutations were identified by PCR and PCR-RFLP, and serum sHLA-G quantification was performed by ELISA. For the 14bp INS/DEL polymorphism, variants frequencies were similar in patients and controls, whereas a significant increased frequency of the +3142 G allele was found in MS patients compared to HD (63.4% vs 52.3%, p=0.04; OR=1.58, 95%CI=1.003-2.48). In addition, an association was found between MS susceptibility and the haplotypes regrouping both studied polymorphisms. Indeed, the 14bp DEL/+3142 G haplotype frequency was significantly increased in MS patients compared to HD (20.8% vs 12.5%, p=0.04, OR=1.84). On the other hand, no associations were detected between both polymorphisms and clinical parameters, except the lower age of disease onset (ADO) in patients with the +3142 C/C genotype. Moreover, our study doesn't show any significant variation of sHLA-G serum levels between patients and controls. Our findings showed that the +3142 C>G, but not the 14bp INS/DEL, polymorphism may constitute a genetic susceptibility factor to MS in the Tunisian population. However, no association was found between the two polymorphisms and sHLA-G serum levels.

  9. Relationship between Interleukin-6 (−174G/C and −572C/G) Promoter Gene Polymorphisms and Risk of Intracerebral Hemorrhage: A Meta-Analysis

    2016-01-01

    Background Polymorphisms of −174G/C and −572C/G in the Interleukin-6 (IL-6) promoter gene can affect both transcription and secretion of IL-6 and may be involved in the inflammatory mechanisms in early and delayed phases after intracerebral hemorrhage (ICH). The role of these polymorphisms remains unclear for the pathogenesis of ICH. Methods PubMed, EMBASE, MEDLINE and Google Scholar searches were conducted from January 1, 1950 to February 29, 2016 and were supplemented with relevant articles identified in the references. The following search terms were used: (‘interleukin-6’ or ‘IL-6’) and (‘genetic polymorphism’ or ‘single nucleotide polymorphisms’ or ‘SNP’) and (‘intracerebral hemorrhage’ or ‘ICH’) and (‘hemorrhagic stroke’ or ‘HS’). Fixed or random effects models were used to estimate the pooled odds ratios and 95% confidence intervals. Begg's funnel plot was used to assess the potential for publication bias. Results In our meta-analysis, three case-control studies involving 446 ICH cases and 2,322 controls were included. No significant association was observed for the IL-6 (-174G/C and −572C/G) gene polymorphisms with the risk of ICH under dominant, recessive and allelic models. Conclusion Our meta-analysis suggests that IL-6 gene polymorphisms are not associated with the risk of ICH. However, caution must be taken while considering the results of our meta-analysis due to the presence of small sample size. Our results cannot be extrapolated to represent the effect of entire IL-6 genetic polymorphism on stroke patients worldwide. Therefore, further well-designed studies with large sample size are warranted to validate our findings and provide a profound conclusion.

    The safety of Aquaflor® (50% w/w florfenicol [FFC]) incorporated in feed then administered to tilapia for 20 days (2x the recommended duration) at 0, 15, 45, or 75 mg/kg body weight/day (0, 1, 3, or 5x the recommended dose of 15 mg FFC/kg BW/d) was investigated. Mortality, behavioral change, feed consumption, body size, and gross and microscopic lesions were determined. Estimated delivered doses were >96.9% of target. Three unscheduled mortalities occurred but were considered incidental since FFC-related findings were not identified. Feed consumption was only affected during the last 10 dosing days when the 45 and 75 mg/kg groups consumed only 62.5% and 55.3% of the feed offered, respectively. There were significant, dose-dependent reductions in body size in the FFC-dose groups relative to the controls. Treatment-related histopathological findings included increased severity of lamellar epithelial hyperplasia, increased incidence of lamellar adhesions, decreased incidence of lamellar telangiectasis in the gills, increased glycogen-type and lipid-type hepatocellular vacuolation in the liver, decreased lymphocytes, increased blast cells, and increased individual cell necrosis in the anterior kidney, and tubular epithelial degeneration and mineralization in the posterior kidney. These changes are likely to be of minimal clinical relevance, given the lack of mortality or morbidity observed. This study has shown that FFC, when administered in feed to tilapia at the recommended dose (15 mg FFC/kg BW/day) for 10 days would be well tolerated.

    Let G be an arbitrary locally compact Abelian group and let C(G) be the space of all continuous complex-valued functions on G. A closed linear subspace \\mathscr H\\subseteq C(G) is referred to as an invariant subspace if it is invariant with respect to the shifts τ_y\\colon f(x)\\mapsto f(xy), y\\in G. By definition, an invariant subspace \\mathscr H\\subseteq C(G) admits strict spectral synthesis if \\mathscr H coincides with the closure in C(G) of the linear span of all characters of G belonging to \\mathscr H. We say that strict spectral synthesis holds in the space C(G) on G if every invariant subspace \\mathscr H\\subseteq C(G) admits strict spectral synthesis. An element x of a topological group G is said to be compact if x is contained in some compact subgroup of G. A group G is said to be element-wise compact if all elements of G are compact. The main result of the paper is the proof of the fact that strict spectral synthesis holds in C(G) for a locally compact Abelian group G if and only if G is element-wise compact.

    -99% pure population of leukocytes. Viability was assessed using Trypan blue histological analysis. We successfully isolated and labeled ~25-30 x 10{sup 7} CD34+ lymphocytes in cytokine mobilized progenitor cell apharesis harvests. Cells were also subjected to a stat gram stain to look for bacterial contamination, stat endotoxin LAL to look for endotoxin contamination, flow cytometry for evaluation of the purity of the cells and 14-day sterility culture. Colony forming assays confirm the capacity of these cells to proliferate and function ex-vivo with CFU-GM values of 26 colonies/ 1 x 10{sup 4} cells plated and 97% viability in cytokine augmented methylcellulose at 10-14 days in CO{sub 2} incubation. We developed a closed-processing system for the product labeling prior to infusion to maintain autologous cell integrity and sterility. Release criteria for the labeled product were documented for viability, cell count and differential, and measured radiolabel. We were successful in labeling the cells with up to 500 uCi/10{sup 8} cells, with viability of >98%. However, due to delays in getting the protocol approved by the FDA, the cells were not infused in humans in this location (although we did successfully use CD34+ cells in humans in a study in Australia). The approach developed should permit labeling of progenitor cells that can be administered to human subjects for tracking. The labeling approach should be useful for all progenitor cell types, although this would need to be verified since different cell lines may have differential radiosensitivity.

    Prevalences of human herpesvirus-8 (HHV-8) infection and diabetes mellitus are very common in certain parts of Africa, containing iron-rich soils. We hypothesized that some genetic factors could have a link with susceptibility to HHV-8 infection. We focused on ferroportin Q248H mutation (rs11568350), transferrin (TF) polymorphism and fructosamine-3 kinase (FN3K) 900C/G polymorphism (rs1056534). The study population consisted of 210 type 2 diabetic adults and 125 healthy controls recruited in Bukavu (South Kivu). In the whole study population (diabetics+healthy controls), ferroportin Q248H mutation was detected in 47 subjects (14.0%) with 43 heterozygotes and 4 homozygotes. TF phenotype frequencies were 88.1% (CC), 10.4% (CD) and 1.5% (BC). Genotype frequencies of FN3K 900C/G polymorphism were respectively 9,3% (CC), 43.3% (GC) and 47.4% (GG). Prevalence of HHV8-infection in the study population was 77.3%. HHV-8 infection rate and HHV-8 IgG antibody titer were significantly higher in diabetics then in controls (p<0.0001). Significant differences were observed in HHV-8 infection rate and in HHV-8 IgG antibody titer according to FN3K rs1056534 (p<0.05 and p<0.05, respectively) and TF polymorphism (p<0.05 and p=0.005, respectively). No significant differences in HHV-8 infection rate and in HHV-8 IgG antibody titer were observed in the ferroportin Q248H mutation carriers (rs11568350) in comparison with ferroportin wild type. In a multiple regression analysis, FN3K rs1056534, TF polymorphism and presence of diabetes mellitus were predictors for HHV-8 infection. In contrast to these findings, ferroportin Q248H mutation (rs11568350) did not influence the susceptibility for an HHV-8 infection in sub-Saharan Africans. Copyright © 2016 Elsevier B.V.

    The main scientific objective of the Comet Nucleus Sounding Experiment by Radiowave Transmission (CONSERT) aboard ESA spacecraft Rosetta is the dielectric characterization of comet 67P/Churyumov-Gerasimenko's nucleus. This was done by means of bi-static radio propagation measurements of the CONSERT instrument between the lander Philae launched onto the comet's surface and the orbiter Rosetta. The CONSERT unit aboard the lander was receiving and processing the radio signal emitted by the orbiter counterpart of the instrument. The lander unit was then retransmitting a signal back to the orbiter. This happened at a time scale of milliseconds. In addition to the operation at the first science sequence, CONSERT was operated during the separation and descent of Philae onto the comet's surface. During the descent phase of Philae the received CONSERT signal was a superposition of the direct propagation path between Rosetta and Philae and indirect paths caused by reflections of 67P/C-G's surface. From peak power measurements of the dominant direct path between Rosetta and Philae during the descent we were able to reconstruct the lander's attitude and estimate the spin rate of the lander along the descent trajectory. Certain operations and manoeuvres of orbiter and lander, e.g. the deployment of the lander legs and CONSERT antennas or the orbiter change of attitude in order to orient the science towards the assumed lander position, are also visible in the CONSERT data. The information gained on the landers attitude is used in the reconstruction of the dielectric properties of 67P/C-G's surface and near subsurface (metric to decametric scale). During roughly the last third of the descent, the comet's surface is visible for the CONSERT instrument enabling a mean permittivity estimation of the surface and near subsurface covered by the instruments footprint along the descent path. The comparatively large timespan with surface signatures exhibits a good spatial diversity

    2009-01-01

    In this paper we analyze the open Feynman graphs of the Colored Group Field Theory introduced in [arXiv:0907.2582]. We define the boundary graph $\\cG_{\\partial}$ of an open graph $\\cG$ and prove it is a cellular complex. Using this structure we generalize the topological (Bollobas-Riordan) Tutte polynomials associated to (ribbon) graphs to topological polynomials adapted to Colored Group Field Theory graphs in arbitrary dimension.

  16. Bion and C.G. Jung. How did the container-contained model find its thinker? The fate of a cryptomnesia.

    Maier, Christian

    2016-04-01

    This paper investigates the possible impact of C.G. Jung's Tavistock Lectures on Bion's concept of the living container. In the first part of the paper, the author offers clues pointing to such an essential impact, which can be found in text passages as well as in the facts of the Bion-Beckett case, up to and including Bion's first publication of 'The imaginary twin'. The author suggests that cryptomnesia is the result of repression targeting a highly cathected author's communication which functions like a deep interpretation for the recipient, whose new theory then is a return of the repressed content as well as a transformation of it. The second part of the paper investigates the fate of the assumed cryptomnesia. From this point of view Bion's concept of the container in itself appears to be the result of growth in the container-contained mode. Finally the author deals with the question whether cryptomnesia in psychoanalytical literature can frequently be seen as the result of psychic growth.

    We report the detection of hydrogen chloride, HCl, in diffuse molecular clouds on the line of sight toward the star-forming region W31C (G10.6-0.4). The J = 1-0 lines of the two stable HCl isotopologues, H{sup 35}Cl and H{sup 37}Cl, are observed using the 1b receiver of the Heterodyne Instrument for the Far-Infrared (HIFI) on board the Herschel Space Observatory. The HCl line is detected in absorption, over a wide range of velocities associated with diffuse clouds along the line of sight to W31C. The analysis of the absorption strength yields a total HCl column density of a few 10{sup 13} cm{sup -2}, implying that HCl accounts for {approx}0.6% of the total gas-phase chlorine, which exceeds the theoretical model predictions by a factor of {approx}6. This result is comparable to those obtained from the chemically related species H{sub 2}Cl{sup +} and HCl{sup +}, for which large column densities have also been reported on the same line of sight. The source of discrepancy between models and observations is still unknown; however, the detection of these Cl-bearing molecules provides key constraints for the chlorine chemistry in the diffuse gas.

    We report the detection of hydrogen chloride, HCl, in diffuse molecular clouds on the line of sight towards the star-forming region W31C (G10.6-0.4). The J = 1-0 lines of the two stable HCl isotopologues, H35Cl and H37Cl, are observed using the 1b receiver of the Heterodyne Instrument for the Far-Infrared (HIFI) aboard the Herschel Space Observatory. The HCl line is detected in absorption, over a wide range of velocities associated with di?use clouds along the line of sight to W31C. The analysis of the absorption strength yields a total HCl column density of few 10^13 cm^-2, implying that HCl accounts for ~0.6 % of the total gasphase chlorine, which exceeds by a factor of ~6 the theoretical model predictions.

    Expression of human leukocyte antigen G (HLA-G) has been associated with increased graft survival and decreased rejection episodes. It has been described that the HLA-G 14-base pair (bp) insertion/deletion (ins/del) (rs66554220) and +3142C>G (rs1063320) gene polymorphisms modify the expression level of HLA-G. The aim of the study was to investigate whether these HLA-G polymorphisms have an impact on acute rejection after liver transplantation. In total, 146 liver transplant recipients (57 with acute rejection and 89 without acute rejection) and 99 corresponding liver donors were genotyped for both polymorphisms. In liver transplantation the 14-bp ins/ins and the +3142GG genotypes are more frequent in recipients without rejection compared to recipients with rejection (3.5% vs. 31.5%, p=In contrast, in liver donors we could not reveal an association. We conclude that 14-bp ins/ins and +3142GG genotypes of HLA-G in liver transplant recipients are of importance for prediction of acute rejection after liver transplantation. Thus genotyping of liver recipients for both polymorphisms might be useful to stratify liver transplant recipients according to the risk of acute liver transplant rejection.

  20. The rates of G:C[yields]T:A and G:C[yields]C:G transversions at CpG dinucleotides in the human factor IX gene

    The authors have identified eight independent transversions at CpG in 290 consecutive families with hemophilia B. These eight transversions account for 16.3% of all independent transversions in the sample, yet the expected frequency of CpG transversions at random in the factor IX gene is only 2.6% (P<0.1). The aggregate data suggest that the two types of CpG transversions (G:C[yields]T:A and G:C[yields]C:G) possess similar mutation rates (24.8 [times] 10[sup [minus]10] and 20.6 [times] 10[sup [minus]10], respectively), which are about fivefold greater than the comparable rates for transversions at non-CpG dinucleotides. The enhancement of transversions at CpG suggest that the model by which mutations occur at CpG may need to be reevaluated. The relationship, if any, between deamination of 5-methyl cytosine and enhancement of transversions at CpG remains to be defined. 28 refs., 2 tabs.

  1. Frobenius groups of automorphisms and their fixed points

    2010-01-01

    Suppose that a finite group $G$ admits a Frobenius group of automorphisms $FH$ with kernel $F$ and complement $H$ such that the fixed-point subgroup of $F$ is trivial: $C_G(F)=1$. In this situation various properties of $G$ are shown to be close to the corresponding properties of $C_G(H)$. By using Clifford's theorem it is proved that the order $|G|$ is bounded in terms of $|H|$ and $|C_G(H)|$, the rank of $G$ is bounded in terms of $|H|$ and the rank of $C_G(H)$, and that $G$ is nilpotent if $C_G(H)$ is nilpotent. Lie ring methods are used for bounding the exponent and the nilpotency class of $G$ in the case of metacyclic $FH$. The exponent of $G$ is bounded in terms of $|FH|$ and the exponent of $C_G(H)$ by using Lazard's Lie algebra associated with the Jennings--Zassenhaus filtration and its connection with powerful subgroups. The nilpotency class of $G$ is bounded in terms of $|H|$ and the nilpotency class of $C_G(H)$ by considering Lie rings with a finite cyclic grading satisfying a certain `selective ni...

    Grape composition, which affects the wine sensory qualities, depends on vine features (rootstock, scion, vine health) and vineyard management as much as environmental factors. Mapping soil at the vineyard scale, in particular, helps in optimizing the terroir expression of the wine. The terroir effect however varies year by year, depending on the interaction of several factors, such as climate and soil. Aim of this research work was to set up a methodology to delineate homogeneous harvest zones (HZ) in the vineyard and to evaluate the vintage effect in them. Four terroir macro-units suitable for premium Sangiovese wine, which is the main cultivar of Chianti D.O.C.G., were selected within a wide farm of Chianti Classico district (Siena, Central Italy). The selected macro-units are representative of the most common and suitable viticultural environments of the Chianti Classico D.O.C.G. and include: 1) hills of high altitude (450-500 m a.s.l.) on feldspathic sandstones, with shallow sandy soils; 2) hills of high altitude (400-500 m a.s.l.) on calcareous flysches, with stony, clayey and calcareous soils; 3) hills of moderate altitude (250-350 m a.s.l.) on Pliocene sandy marine deposits; 4) hills and fluvial terraces of moderate altitude (200-300 m a.s.l., 50-100 m above the present river valley) on ancient fluvial deposits. Each terroir macro-unit was surveyed by soil proximal sensing, to define two homogeneous zones (HZs) in terms of soil physics and hydrology. The proximal sensors used to map the HZs were: i) γ-ray spectrometer, to map the variability of soil surface in terms of parent material, texture and stoniness; ii) electromagnetic induction sensor (EMI) to determine the spatial variability of texture and soil moisture in the sub-surface horizons. Thus, the soil moisture of each HZ was monitored during spring shoot growth (beginning of April), berries veraison (end of July-beginning of August) and final ripening phase before harvest (September).

    The safety profile of afoxolaner (an isoxazoline molecule) when combined with milbemycin oxime (a macrocyclic lactone) was evaluated according to the regulatory requirements when administered six times orally in a soft chewable formulation at a dose of at least 1×, 3×, or 5× the maximum exposure dose in 8-week-old Beagle dogs. Thirty-two healthy puppies (16 males and 16 females) were enrolled and allocated randomly to one of four treatment groups. Three doses were administered at 28-day intervals (Days 0, 28, and 56), followed by three additional doses administered with 14-day intervals (Days 84, 98, and 112). The study ended on Day 126. Treatment groups were as follows: Group 1: untreated, sham-dosed control; Group 2: afoxolaner/milbemycin oxime chews administered at a dose of at least 5 and 1 mg/kg, respectively (1×); Group 3: afoxolaner/milbemycin oxime chews administered at a dose of at least 15 and 3 mg/kg, respectively (3); and Group 4: afoxolaner/milbemycin oxime chews administered at a dose of at least 25 and 5 mg/kg, respectively (5×). All dogs were examined for general health twice a day beginning on Day -14. Physical examinations, and blood collections for clinical pathology analysis and afoxolaner and milbemycin oxime plasma concentrations, were performed throughout the study. No afoxolaner/milbemycin oxime treatment-related changes were observed in growth, physical variables, clinical pathology variables, or tissues examined histologically. No clinically relevant or statistically significant health abnormalities related to the administration of afoxolaner/milbemycin oxime were observed. No signs of macrocyclic lactone sensitivity were observed at any time during the study. Vomiting and diarrhea were observed sporadically across all groups including the controls. Based upon the results of this study, afoxolaner/milbemycin oxime soft chewables were shown to be safe when administered repeatedly at up to 5× the maximum exposure dose in dogs as

    Let $G$ be a Camina $p$-group of nilpotence class $3$. We prove that if $G' < C_G (G')$, then $|Z(G)| \\le |G':G_3|^{1/2}$. We also prove that if $G/G_3$ has only one or two abelian subgroups of order $|G:G'|$, then $G' < C_G (G')$. If $G/G_3$ has $p^a + 1$ abelian subgroups of order $|G:G'|$, then either $G' < C_G (G')$ or $|Z(G)| \\le p^{2a}$.

    The relationships between host immune factors and HIV-1 disease progression are still in dispute. The RANTES SNPs exhibit distinct ethnic distribution and are associated with different effects on the course of HIV infection. Therefore, impact of RANTES gene polymorphism on HIV-1 transmission and progression needs to be evaluated. The RANTES genotypes were identified by PCR-RFLP method and confirmed by sequencing in HIV-1 seronegative (HSN; n=315), HIV-1 exposed seronegative (HES; n=47) and HIV-1 seropositive (HSP; n=196) patients classified into different clinical stages (i.e. Stages I, II, III). Fisher exact test was used for statistical analysis and Arlequin software for haplotype analysis. RANTES allele -403G, -28C and In1.1 T were the predominant allele in the subject studied. HSP group have higher frequency of RANTES In1.1 T allele compared with HSN (91.32% vs. 86.19%; P=0.013) and HES (91.32% vs. 78.72%; P=0.001). Higher frequency of RANTES In1.1 C allele in Stage III was observed, compared with Stage I (14.28% vs. 6.39%) and was significantly associated with high risk (P=0.047, OR=2.439, C.I.=1.061-5.609). Haplotype II (ACT) was significantly higher in HSP compared with HSN (9.69% vs. 1.58%) and associated with high risk (P403 A/G and -28 C/G genotype and allele distribution in all the groups compared. Our results implicate that RANTES In1.1 T allele and haplotype II (ACT) may be a risk factor for HIV-1 transmission while RANTES In1.1 C allele may be risk factor for disease progression among North Indians.

    We investigated whether the recommended phenobarbital loading dose of 15-20 mg/kg with maintenance of 3-4 mg/kg/day can safely be administered to very low birth weight preterm newborns with seizures. Twenty-four convulsive preterms of Phenobarbital was administered intravenously with a loading dose of 15 mg/kg in approximately 10-15 min. After 24 h, the maintenance dose of 3 mg/kg/day was administered as a single injection. Blood samples were obtained 2, 24, 48, 72, and 96 h after the phenobarbital loading dose was administered, immediately before the next phenobarbital dose was injected. None of the cases had plasma phenobarbital concentrations above the therapeutic upper limit of 40 μg/mL on the 2nd hour; one case (4.7%), on the 24th; 11 cases (45.8%), on the 48th; 15 cases (62.5%), on the 72nd; and 17 cases (70.8%), on the 96th hour. A negative correlation was detected between the serum concentrations of phenobarbital and gestational age on the 72th (p, 0.036; r, -0.608) and 96th hour (p, 0.043; r, -0.769). We suggest that particular attention should be done while administering phenobarbital in preterms, as blood levels of phenobarbital are higher than the reference ranges that those are often reached with the recommended doses in these groups of babies.

    Objective: To explore the relationships among atrial fibrillation (AF), interleukin-6 (IL-6) and single nucleotide polymorphisms (SNP) of the IL-6-174G/C, -572C/G and -597G/A. Methods: The serum levels of IL-6, lipid and other clinical indicators were measured. The left atrial diameter (LAD) was measured by echocardiography (UCG). The frequency distributions of genotypes and alleles of the IL-6-174G/C, -572G/C and -597G/A were amplified by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in samples of 127 AF patients. Results: The values of IL-6 and LAD were significantly higher in AF group than those of control group (P < 0.01). The G/C+G/G genotype distribution and G allele frequencies of IL-6-572C/G were signif'icantly higher in AF group than those of control group (P < 0.01). The C allele mutation rate of IL-6-174G/C was minimal in Han population in Jiangsu Nantong, and no A allele mutation in IL-6-597G/A. Conclusion: The results showed that among Han population in Nantong IL-6-572 C/G polymorphic allele G mutation may lead to the increase of serum level of IL-6 in AF group , which may be related to the pathogenesis of AF.%目的:探讨江苏南通地区汉族人群中白细胞介素(IL)-6-174G/C(rs18007951、-572C/G(rs1800796)、-597G/A(rs1800797)单核苷酸多态性(SNP)与血清IL-6水平以及房颤发病之间的关系.方法:分别测定房颤组和对照组血清IL-6及其他临床指标,测量左心房长径(LAD);提取基因组DNA.聚合酶链反应-限制性片段长度多态性(PCR-RFLP)技术扩增目的基因片段并酶切.结果:房颤组IL-6和LAD与对照组比较差异有统计学意义(P<0.01);房颤组IL-6-572C/G基因型分布G/C+G/G明显高于对照组(P<0.05),且房颤组G等位基因频率明显大于对照组(P<0.01),IL-6-174G/C位点C等位基因突变率极低,IL-6-597G/A未见A等位基因突变.结论:IL-6-572C/G位点G等位基因突变导致了机体血清IL一6水平升高,可能与房颤的发病有关.

    The safety profile of afoxolaner, a new isoxazoline molecule, was evaluated following the regulatory requirements when administered six times orally in a soft chewable formulation at a dose of at least 1×, 3× or 5× the maximum exposure dose (6.3mg/kg) in 8-week-old Beagle dogs. Thirty-two healthy puppies (16 males and 16 females) were enrolled and allocated randomly to one of four treatment groups. Treatments were administered at three, one-month dose intervals (Days 0, 28 and 56) followed by three, 2-week dose intervals (Days 84, 98 and 112). The study ended at Day 126. The groups were: Group 1: non-treated control; Group 2: afoxolaner chews administered at a dosage of at least 6.3mg/kg (1×); Group 3: afoxolaner chews administered at a dosage of at least 18.9 mg/kg (3×); and Group 4: afoxolaner chews administered at a dosage of at least 31.5mg/kg (5×). All dogs were examined for general health twice a day beginning on at least Day-14. Physical examinations, and blood collections for clinical pathology analysis and afoxolaner plasma concentrations, were performed throughout the study. On Day 126, 2 weeks following the last treatment, all dogs were humanely euthanized prior to the conduction of a full necropsy with tissue collection. No afoxolaner-related changes were observed in growth, physical variables, clinical pathology variables, or tissues examined histologically. No clinically or statistically significant health abnormalities related to the administration of afoxolaner were observed. Vomiting and diarrhea were observed sporadically across all groups including the controls. The kinetics of afoxolaner plasma concentrations was linear following 6 doses of 6.3, 18.9 and 31.5mg/kg and dose proportionality was demonstrated. There were no statistical differences (pafoxolaner was shown to be safe when administered repeatedly in a soft chewable formulation at up to 5× the maximum exposure dose in dogs as young as 8 weeks of age.

    Full Text Available This is a survey article on centralizers of finitesubgroups in locally finite, simple groups or LFS-groups as wewill call them. We mention some of the open problems aboutcentralizers of subgroups in LFS-groups and applications of theknown information about the centralizers of subgroups to thestructure of the locally finite group. We also prove thefollowing: Let $G$ be a countably infinite non-linear LFS-groupwith a Kegel sequence $mathcal{K}={(G_i,N_i | iinmathbf{N} }$. If there exists an upper bound for ${ |N_i| |iin mathbf{N} }$, then for any finite semisimplesubgroup $F$ in $G$ the subgroup $C_G(F$ has elements oforder $p_i$ for infinitely many distinct prime $p_i$. Inparticular $C_G(F$ is an infinite group. This answers Hartley'squestion provided that there exists a bound on ${ |N_i| | iin mathbf{N}$.

    Full Text Available The study was conducted to evaluate the effects of romifidine alone (50 µg/kg and a combination of romifidine (50 µg/kg and ketamine (2.5 mg/kg after intrathecal administration in goats. Ten adult goats of either sex weighing between 15 and 20 kg were randomly placed in 2 groups (groups I and II. The agents were administered at the lumbosacral subarachnoid space. Clinico-physiological parameters such as analgesia, motor incoordination, sedation, salivation, heart rate, respiratory rate, arterial pressure, central venous pressure and rectal temperature were studied. Other haematobiochemical parameters monitored were packed cell volume, haemoglobin, plasma proteins, glucose, urea and creatinine. The onset of analgesia was faster in group II (35.5 ±6.25 s compared to that of group I (5.2 ±0.54 min. Analgesia of the tail, perineum, hind limbs, flank and thorax was mild to moderate in group I, but complete analgesia of tail, perineum and hind limbs was recorded in group II. Motor incoordination was mild in group I and severe in group II. Significant reduction in heart rate (more pronounced in group I and respiratory rate (more pronounced in group II, and a significant increase in central venous pressure were recorded in both groups. Mean arterial pressure was reduced in both groups, but more markedly in group I. Sedation, electro-cardiogram, rectal temperature and haemato-biochemical parameters did not show significant differences between the 2 groups. The results of this study indicated a possible synergistic analgesic interaction between intrathecally administered romifidine and ketamine, without causing any marked systemic effects in goats.

    The behavioral outcomes of a calorie restricted diet are often neglected in favour of a more physiological examination of the consequences of calorie restriction (CR). This is especially the case with social behavior. A few findings within the maternal CR literature suggest that adult male social behavior is altered by this regimen. Despite the paucity of findings within the maternal CR literature, a systematic investigation of the behavioral phenotype of males administered an adult-onset CR is completely lacking and was the focus of the current study. Adult male hooded Wistar rats were administered a three week CR, with one group receiving a 25% CR and another group receiving a 50% CR before male-to-male social behavior was examined and compared with ad libitium fed males. Various behavioral elements were modulated by CR, both the CR25% and 50% group initiated contact sooner and engaged in greater social activity compared to the ad libitum fed controls. The CR25% group also demonstrated less non-social (self-grooming) behavior and a greater frequency of walkovers compared to all groups, indicating a propensity towards dominance. The CR50% group demonstrated greater environmental assessment/exploration, as measured by the frequency of rearing. As with the maternal CR literature, an adult-onset chronic CR induces a more socially active behavioral phenotype and reduces interest in non-social behavior in the moderately CR group. Taken together, the social behavioral phenotype can be modulated by a CR initiated and maintained during adulthood.

    There is a need to compare propofol requirement between propofol-ketamine (PK) and propofol-fentanyl (PF) given as nonanesthetist-administered propofol sedation during pediatric esophagogastroduodenoscopy (EGD). The study was a parallel-group, randomized, double-blind comparison of the need for additional doses of propofol in the first minute after sedation induction between PK and PF, administered by rotating trainees in pediatrics for sedation during pediatric EGD. A total of 95 children with American Society of Anesthesiologists class I to III between 3 and 12 years undergoing EGD were included and randomized to either of the groups. After midazolam premedication, children received either 0.5 mg/kg ketamine (PK) or 1 μg/kg of fentanyl (PF) followed by a mandatory 1 mg/kg of propofol. Additional doses of propofol of 0.5 mg/kg each were given to achieve sedation induction (modified Ramsay scale level 6), and further doses were administered during the procedure as required. A total of 92 children (PK, n = 47; PF, n = 45) were analyzed. P propofol dose required for successful scope introduction and also in the need for additional propofol doses and the total additional propofol doses required in the first minute after sedation induction. Propofol injection pain was higher in the PF group (odds ratio 1.78). The adverse events and recovery time were similar. There was no escalation of care, airway intubations, death, or disability. Nonanesthetist-administered propofol sedation is feasible in teaching hospitals. Propofol requirement is similar in both PK and PF combination regimens, but the lower frequency of propofol injection pain may favor the use of PK.

    Full Text Available Abstract Background In primary care, it is often difficult to diagnose cervical myelopathy. However, a delay in treatment could cause irreversible aftereffects. With a brief and effective self-administered questionnaire for cervical myelopathy, cervical myelopathy may be screened more easily and oversight may be avoided. As there is presently no screening tool for cervical myelopathy, the aim of this study was to develop a self-administered questionnaire for the screening of cervical myelopathy. Methods A case-control study was performed with the following two groups at our university hospital from February 2006 to September 2008. Sixty-two patients (48 men, 14 women with cervical myelopathy who underwent operative treatment were included in the myelopathy group. In the control group, 49 patients (20 men, 29 women with symptoms that could be distinguished from those of cervical myelopathy, such as numbness, pain in the upper extremities, and manual clumsiness, were included. The underlying conditions were diagnosed as carpal tunnel syndrome, cubital tunnel syndrome, thoracic outlet syndrome, tarsal tunnel syndrome, diabetes mellitus neuropathy, cervical radiculopathy, and neuralgic amyotrophy. Twenty items for a questionnaire in this study were chosen from the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire, which is a new self-administered questionnaire, as an outcome measure for patients with cervical myelopathy. Data were analyzed by univariate analysis using the chi-square test and by multiple logistic regression analysis. According to the resulting odds ratio, β-coefficients, and p value, items were chosen and assigned a score. Results Eight items were chosen by univariate and multiple logistic regression analyses and assigned a score. The Hosmer-Lemeshow statistic showed p = 0.805. The area under the receiver operation characteristic curve was 0.86. The developed questionnaire had a sensitivity of 93.5% and a

    Although many analyses of S-1 side effects are reported, there are no reports where the analyses of side effects were performed in consideration of renal function, which is an important index of medication dose. Therefore, we investigated side effects in consideration of renal function. The subjects were 163 patients administered S-1 at the Department of Surgery of Ogaki Municipal Hospital, between October 2008 and December 2009. The frequency and severity of side effects were high and serious in the groupwhose creatinine clearance was low. A significant difference was observed among 3 groups with regard to thrombocytopenia and dehydration. In conclusion, we think that pharmacists must take renal function into consideration when administering medication, to keepclose medicinal guidance, and to actively observe progress.

    Despite biological support for a role of Beta-site APP-cleaving enzyme 1 (BACE1) in sporadic Alzheimer's disease (SAD), studies about the BACE1 genetic polymorphisms in SAD are inconsistent. To explore whether the BACE1 polymorphisms confers susceptibility to SAD, the current meta-analysis was conducted to evaluate the gene-disease association in relevant studies. The serious databases were researched to identify studies. The association between BACE1 (exon5 C/G, intron 5 T/G or 3'UTR T/A) polymorphism and SAD risk was evaluated by odds ratios (ORs) together with their 95% confidence intervals (CIs). The combined results showed no significant difference in all models on the basis of all studies for BACE1 (exon5 C/G, intron 5 T/G or 3'UTR T/A) polymorphisms. When subgroup analysis was performed based on ethnicity and the epsilon 4 allele of apolipoprotein E (APOEε4) carriers status, significant associations were demonstrated (CC versus CG+GG: OR=1.37, 95% CI=1.04-1.82, P=0.03BACE1 (exon5 C/G, intron 5 T/G or 3'UTR T/A) polymorphism could be not a risk factor for SAD. However, individuals with CC genotype have higher risk of SAD with APOEε4 carrier status, and gene-gene interaction might affect on the association. Further studies with large sample size, especially in subgroup analysis, should be done to confirm these findings.

    Calcium gluconate was administered to conscious horses at 3 different rates (0.1, 0.2, and 0.4 mg/kg/min for 15 minutes each). Serum calcium concentrations and parameters of cardiovascular function were evaluated. All 3 calcium administration rates caused marked increases in both ionized and total calcium concentrations, cardiac index, stroke index, and cardiac contractility (dP/dtmax). Mean arterial pressure and right atrial pressure were unchanged; heart rate decreased markedly during calcium administration. Ionized calcium concentration remained between 54% and 57% of total calcium concentration throughout the study. We conclude that calcium gluconate can safely be administered to conscious horses at 0.1 to 0.4 mg/kg/min and that administration will result in improved cardiac function.

    Explosions account for 79% of combat-related injuries, leading to multiorgan hemorrhage and uncontrolled bleeding. Uncontrolled bleeding is the leading cause of death in battlefield traumas as well as in civilian life. We need to stop the bleeding quickly to save lives, but, shockingly, there are no treatments to stop internal bleeding. A therapy that halts bleeding in a site-specific manner and is safe, stable at room temperature, and easily administered is critical for the advancement of trauma care. To address this need, we have developed hemostatic nanoparticles that are administered intravenously. When tested in a model of blast trauma with multiorgan hemorrhaging, i.v. administration of the hemostatic nanoparticles led to a significant improvement in survival over the short term (1 h postblast). No complications from this treatment were apparent out to 3 wk. This work demonstrates that these particles have the potential to save lives and fundamentally change trauma care.

    Full Text Available Background. Fetal tachycardia may result from the transplacental passage of thyroid stimulating immunoglobulins in a patient with hypothyroidism secondary to ablation of Graves’ disease. Case. A 32-year-old woman, gravida 4, para 2, and abortus 1, with hypothyroidism and a history of Graves’ disease, presented at 23 6/7 weeks of gestation with a persistent fetal tachycardia. The treatment of the fetal tachycardia with maternally administered digoxin and Sotalol was unsuccessful. Maternal thyroid stimulating immunoglobulins were elevated, and treatment with maternally administered propylthiouracil (PTU resulted in a normal sinus rhythm for the remainder of the pregnancy. An induction of labor was performed at 37 weeks. Four to five days after delivery, the neonate exhibited clinical signs of hyperthyroidism necessitating treatment. Conclusion. Fetal tachycardia resulting from the transplacental passage of thyroid stimulating immunoglobulins can be successfully treated with maternally administered PTU. The neonate needs to be followed up closely as clinical signs of hyperthyroidism may occur as thyroid stimulating immunoglobulins continue to circulate in the neonate, while the serum levels of PTU decline.

    Sorghum downy mildew caused by Peronosclerospora sorghi is a major disease of maize and resistance is under the control of polygenes which necessitated identification of quantitative-trait loci (QTLs) for initiating marker-assisted introgression of resistant QTLs in elite susceptible inbred lines. In the present study, QTLs for sorghum downy mildew (SDM) resistance in maize were identified based on cosegregation with linked simple sequence repeats in 185 F2 progeny from a cross between susceptible (CM500-19) and resistant (MAI105) parents. F3 families were screened in the National Sorghum Downy Mildew Screening Nursery during 2010 and 2011. High heritability was observed for the disease reaction. The final map generated using 87 SSR markers had 10 linkage groups, spanning a length of 1210.3 cM. Although, we used only 87 SSR markers for mapping, the per cent of genome within 20 cM to the nearest marker was 88.5. Three putative QTLs for SDM resistance were located on chromosomes 3 (bin 3.01), 6 (bin 6.01) and 2 (bin 2.02) using composite interval mapping. The locus on chromosome 3 had a major effect and explained up to 12.6% of the phenotypic variation. The other two QTLs on chromosomes 6 and 2 had minor effects with phenotypic variation of 7.1 and 2%. The three QTLs appeared to have additive effects on resistance. The QTLs on chromosomes 3 and 6 were successfully used in the marker-assisted selection programme for introgression of resistance to SDM in eight susceptible maize lines.

    The effect of subcutaneously injected diclazuril on the output of Eimeria species oocysts was studied in experimentally infected rabbits. Diclazuril was administered either prophylactically at 0.5, 1 or 2 mg/kg bodyweight two days before each rabbit was inoculated with 20,000 oocysts of a mixed-species field isolate of Eimeria or therapeutically at 1, 2 or 4 mg/kg bodyweight five days after they were inoculated. The prophylactic treatments significantly reduced (PEimeria stiedae, Eimeria magna, Eimeria irresidua, Eimeria flavescens, Eimeria piriformis and Eimeria intestinalis was significantly reduced (P<0.05) in all the treated groups. The burden of oocysts in the livers of the therapeutic groups (4000 to 9000) were significantly lower (P<0.05) than in the inoculated but untreated control group (23,000), but higher than in the prophylactic groups (around 1000).

    The 2 antidotes for acute cyanide poisoning in the United States must be administered by intravenous injection. In the out-of-hospital setting, intravenous injection is not practical, particularly for mass casualties, and intramuscular injection would be preferred. The purpose of this study is to determine whether sodium nitrite and sodium thiosulfate are effective cyanide antidotes when administered by intramuscular injection. We used a randomized, nonblinded, parallel-group study design in 3 mammalian models: cyanide gas inhalation in mice, with treatment postexposure; intravenous sodium cyanide infusion in rabbits, with severe hypotension as the trigger for treatment; and intravenous potassium cyanide infusion in pigs, with apnea as the trigger for treatment. The drugs were administered by intramuscular injection, and all 3 models were lethal in the absence of therapy. We found that sodium nitrite and sodium thiosulfate individually rescued 100% of the mice, and that the combination of the 2 drugs rescued 73% of the rabbits and 80% of the pigs. In all 3 species, survival in treated animals was significantly better than in control animals (log rank test, Pcyanide poisoning in 3 clinically relevant animal models of out-of-hospital emergency care.

    Full Text Available Abstract Background Bowel symptoms are considered indicators of the presence of colorectal cancer and other bowel diseases. Self administered questionnaires that elicit information about lower bowel symptoms have not been assessed for reliability, although this has been done for upper bowel symptoms. Our aim was to develop a self administered questionnaire for eliciting the presence, nature and severity of lower bowel symptoms potentially related to colorectal cancer, and assess its reliability. Methods Immediately before consulting a gastroenterologist or colorectal surgeon, 263 patients likely to have a colonoscopy completed the questionnaire. Reliability was assessed in two ways: by assessing agreement between patient responses and (a responses given by the doctor at the consultation; and (b responses given by patients two weeks later. Results There was more than 75% agreement for 78% of the questions for the patient-doctor comparison and for 92% of the questions for the patient-patient comparison. Agreement for the length of time a symptom was present, its severity, duration, frequency of occurrence and whether or not medical consultation had been sought, all had agreement of greater than 70%. Over all questions, the chance corrected agreement for the patient-doctor comparison had a median kappa of 65% (which represents substantial agreement, interquartile range 57–72%. The patient-patient comparison also showed substantial agreement with a median kappa of 75%, interquartile range 68–81%. Conclusion This self administered questionnaire about lower bowel symptoms is a useful way of eliciting details of bowel symptoms. It is a reliable instrument that is acceptable to patients and easily completed. Its use could guide the clinical consultation, allowing a more efficient, comprehensive and useful interaction, ensuring that all symptoms are assessed. It will also be a useful tool in research studies on bowel symptoms and their predictive

    Chlorpyrifos is a widely used organophosphate insecticide for domestic, agricultural and industrial purposes. Lead is a toxic heavy metal and it is used for domestic and industrial purposes. Taurine is a semi essential amino acid with bioprotective properties. The aim of this study was to investigate the effects of taurine on thyroid function in Wistar rats co-administered with chlorpyrifos and lead. The rats were divided into 5 groups of 10 rats each. The first two groups were administered with distilled water and soya oil (1 ml/kg) respectively. The other groups received taurine (50 mg/kg), chlorpyrifos + lead [chlorpyrifos (4.25 mg/kg, 1/20 median lethal dose] and lead (233.25 mg/kg, 1/20 median lethal dose) and taurine + chlorpyrifos + lead respectively. The treatments were administered once daily by oral gavage for 16 weeks. The rats were euthanized after the completion of the study and the thyroid function and thyroid histoarchitecture were evaluated. The results revealed that co-administration of chlorpyrifos and lead to the rats induced perturbations in thyroid function and this was manifested by reductions in the concentrations of triiodothyronine and thyroxine, increased thyroid stimulating hormone concentration and degeneration of the follicular epithelia of the thyroid gland. Taurine alleviated the perturbations in thyroid function and improved thyroid gland histoarchitecture. The beneficial effects of taurine may be attributed to its ability to protect the body from toxicity and oxidative stress. Taurine may be useful for prophylaxis against disruptions in thyroid function in animals that are exposed to environmental chlorpyrifos and lead.

    The liquid wax obtained from the seeds of the arid-land shrub jojoba (Simmondsia chinensis) is finding increasing use in skin treatment preparations. The fate of this wax upon reaching the digestive tract was studied. 14C-Labeled wax was administered intragastrically to mice, and the distribution of the label in the body was determined as a function of time. Most of the wax was excreted, but a small amount was absorbed, as was indicated by the distribution of label in the internal organs and the epididymal fat. The label was incorporated into the body lipids and was found to diminish with time.

    1985-01-01

    Dermorphin, administered into the third ventricle of conscious rabbits, induces an increase of the total power density spectrum of the cortex and a decrease of the total power of the hippocampus. The electrocortical pattern is similar to that found with other opiates and reported as specific of mu agonists. Simultaneously the peptide causes respiratory depression, bradycardia and hypothermia. Naloxone (0.5 mg/kg IV) quickly and completely inverts all these effects. The activity of serotoninergic, Gabaergic, catecholaminergic and cholinergic systems does not seem to be required for these dermorphin actions. Thus, the hypothesis that dermorphin acts directly in modifying cerebral electrical activity is put forward.

    Although there are numerous self-help books for depression, relatively few have been empirically tested. However, those that have been used in clinical trials have fared well, with an average effect size roughly equivalent to the average effect size obtained in psychotherapy studies. Computer-based treatments are being developed and appear promising as an alternative to bibliotherapy for those interested in self-administered treatments. This article provides a summary of the depression bibliotherapy literature and discusses several remaining questions such as effectiveness versus efficacy, practice applications, ethics, and future research.

    This study investigated the functionality of the Self-Administered Gerocognitive Examination (SAGE) for cognitive screening in community settings and examined its characteristics as a cognitive screening assessment tool. From 45 community events, 1,047 individuals over age 50 were screened with SAGE. Cognitive impairment was identified in 28%. Principal-component and correlation analysis indicate that SAGE is an internally-consistent test that is very well balanced, with language, cognition, visuospatial, executive, and memory domains. Community cognitive screening using SAGE was found to be feasible and efficient in diverse settings with both small and large groups.

    The aim of this 2-week study was to examine the effects of self-administered acupressure intervention onlevels of mood of 54 students (34 males and 20 females) majoring in acupuncture and moxibustion medicineat a college located in Fukuoka, Japan. Eligibility criteria were the ability to complete the intervention accurately and no history of psychiatric diseases. The students were randomly assigned to one of the two groups: an intervention group (IG, n = 28) and a control group (CG, n = 26). The IG participants completed fiveacupressure sessions three times a day (morning, noon, and night), involving the application of pressure to six acupuncture points (GB12, SI17, and LI18 according to 2008 World Health OrganizationRegional Office in the Western Pacific standard), three on the left and three on the right side of the neck for 5 s each. The CG participants were requested to spend their time as usual. Self-reported levels of tension-anxiety, depression-dejection, anger-hostility, vigor, fatigue, and confusion over the past week were measured before and after the study as the main outcomes. Side effects were not predicted and not assessed. The retention rate of this trial was 100%. Improvements in mood, defined as a change from baseline to 2 weeks later, were significantly greater in IG. Our results showed that self-administered intervention had the ability to alter mood levels in college students.

    To derive a precise estimation of the associations between the cytochrome P450 1B1 (CYP1B1) 4326C/G variants and prostate cancer (PCa) risk or aggressiveness, a meta-analysis was performed using all eligible published studies. Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated to assess the association in seven literature studies with 2788 cases and 2968 controls. In the overall analysis, no significant association was found between the CYP1B1 4326C/G polymorphism and PCa risk, but ethnicity subgroup analyses and a case-source analysis revealed significant associations. The 4326G allele showed a significant association with increased PCa risk in Asians (OR=1.52, 95% CI: 1.20-1.92), and significant associations were also observed in a heterozygote comparison (OR=1.40, 95% CI: 1.03-1.89), a homozygote comparison (OR=2.38, 95% CI: 1.31-4.33) and in a dominant genetic model (OR=1.52, 95% CI: 1.14-2.01). Moreover, the 4326G allele was also significantly correlated with an increased risk of sporadic PCa (OR=1.13, 95% CI: 1.04-1.24), and significant associations were observed in a heterozygote comparison (OR=1.16, 95% CI: 1.02-1.33), a homozygote comparison (OR=1.24, 95% CI: 1.03-1.49) and a dominant genetic model (OR=1.19, 95% CI: 1.05-1.34). The overall analyses and all subgroup analyses showed no significant association between the 4326C/G polymorphism and PCa aggressiveness. Our meta-analysis showed that CYP1B1 4326G allele is significantly associated with an increased PCa risk in Asians and in sporadic PCa cases.

    Objective To investigate the effect of succinylcholine on the dose-response relationship of subsequently administered rocuronium in healthy patients. Methods Forty-eight ASA physical status Ⅰ-Ⅱ patients,aged 17 -65 years, scheduled for elective general surgery, were randomly assigned to either the rocuronium treatment group (R) or succinylcholine-rocuronium treatment group (SR). General anesthesia was induced with thiopental 4 to 6mg/kg and fentanyl 2 to 5μg/kg intravenously and maintained with 60% nitrous oxide in oxygen. Additional doses of thiopental or fentanyl were administered as required. The dose-response relationship of rocuronium was determined by the single dose-response technique. In R group ( n =24) , rocuronium was given after induction of anesthesia. In SR group (n =24 ) , patients were intubated after 1.5mg/kg of succinylcholine and rocuronium was given after the complete recovery of neuromuscular blockade from succinylcholine. Patients were further randomly divided into 4 subgroups receiving 150, 200, 250 or 300μg/kg of rocuronium respectively in both groups. Neuromuscular function was assessed accelographically with train-of-four (TOF) stimulation at the wrist every 12s (using the TOF Guard(R) accelerometer). The relationship between probit-tranformed percentage depression of first twitch height (Th) of train-of-four stimulation and logarithm dose of rocuronium was analyzed using linear regression.Results The dose-response curve of rocuronium after succinylcholine was shifted to the left in a parallel fashion compared with that of rocuronium given alone. ED50 and ED95 of rocuronium were 193 ±69 and 367 ± 73μg/kg respectively in R group, and 158 ± 35 and 317 ± 80μg/kg respectively in SR group ( P < 0. 05 ). Conclusion Succinylcholine shifts the dose-response curve of rocuronium to the left and potentiates the effects of the neuromuscular blockade by about 15% of subsequently administered rocuronium. Lower doses of rocuronium are

    Mifepristone and oral misoprostol are typically used for medical abortion in women up to 49 days of gestation, with a 36- to 48-hour interval between the medications. Alternative routes of misoprostol administration allow for use beyond 49 days of gestation. We designed this randomized, noninferiority trial to compare the efficacy, adverse effects, and acceptability of misoprostol 800 mcg vaginally administered simultaneously with, or 24 hours after, mifepristone 200 mg orally for abortion in women up to 63 days of gestation. The 1,128 participants swallowed mifepristone 200 mg and were then randomized to self-administer misoprostol intravaginally immediately in the office (group 1) or 24 hours later at home (group 2). Subjects returned for an evaluation, including transvaginal ultrasonography, 7+/-1 days after initiating treatment. Women who had not aborted were offered a second dose of misoprostol and returned for another evaluation in approximately 1 week. A phone contact was also attempted approximately 5 weeks after treatment. Treatment was considered a failure if a suction aspiration was performed for any indication. The complete abortion rate for group 1 (95.1%, 95% confidence interval [CI] 93.0-96.8%) was statistically noninferior to that for group 2 (96.9%, 95% CI 95.1-98.2%) (P=.003). The abortion rates between groups did not significantly differ by gestational age. Adverse effects were mostly similar, although nausea, diarrhea, and warmth or chills were significantly more common in group 1. Mifepristone 200 mg and misoprostol 800 mcg vaginally used simultaneously is as effective for abortion as compared with regimens using a 24-hour dosing interval.

    (/sup 3/H)-Palmitate labeled natural lamb surfactant and free (/sup 14/C)-choline were mixed with the lung fluid of 11 term lambs at cesarean section, before the first breath. After receiving the isotope, the lambs were delivered, allowed to breathe spontaneously, and were subsequently sacrificed from 5 min to 96 h of age. Alveolar washes, lung homogenates, microsomal and lamellar body fractions of lungs, and pulmonary alveolar macrophages were examined for the presence of labeled phosphatidylcholine. Analysis of the labeled natural surfactant kinetic data revealed an apparent t 1/2 of phosphatidylcholine in the whole lung of 6.0 days. This half-life can be interpreted only as a rough estimate. Appearance of considerable (/sup 3/H) labeled phosphatidylcholine in the lung homogenates demonstrated uptake of phosphatidylcholine from alveoli into lung tissue. The surfactant-associated label in homogenates was localized preferentially to lamellar body fractions. Some of the administered (/sup 14/C)-choline appeared in phosphatidylcholine. Almost all of this labeled phosphatidylcholine was associated with the homogenate. Extremely small % of administered (3H) and (14C) were found in pulmonary alveolar macrophages.

    Management of pain in the pre-hospital setting is often inadequate. In 2011, ambulance personnel were authorized to administer intravenous fentanyl in the Central Denmark Region. The aim of this study was to evaluate the efficacy and safety of intravenous fentanyl administered by ambulance personnel. Pre-hospital medical charts from 2348 adults treated with intravenous fentanyl by ambulance personnel during a 6-month period were reviewed. The primary outcome was the change in pain intensity on a numeric rating scale (NRS) from before fentanyl treatment to hospital arrival. Secondary outcomes included the number of patients with reduction in pain intensity during transport (NRS ≥ 2), the number of patients with NRS > 3 at hospital arrival, and potential fentanyl-related side effects. Fentanyl reduced pain from before treatment (8, IQR 7-9) to hospital arrival (4, IQR 3-6) (NRS reduction: 3, IQR 2-5; P = 0.001), 79.3% of all patients had a reduction in > 2 on the NRS during transport, and 58.4% of patients experienced pain at hospital arrival (NRS > 3). Twenty-one patients (0.9%) had oxygen saturation ambulance personnel. Many patients had moderate to severe pain at hospital arrival. As the protocol allowed higher doses of fentanyl, feedback on effect and safety should be part of continuous education of ambulance personnel. © 2015 The Acta Anaesthesiologica Scandinavica Foundation.

    This meta-analysis was conducted to evaluate the association of transforming growth factor-β1 (TGF-β1) G915C, G800A, C509T gene polymorphism with the risk of diabetic nephropathy (DN). The association literatures were identified from PubMed, Cochrane Library, and CBM-disc (China Biological Medicine Database) on March 1, 2013, and eligible reports were recruited and synthesized. Seven reports were recruited into this meta-analysis for the association of TGF-β1 G800A, C509T, G915C gene polymorphism with DN risk. GG genotype, CC genotype, and C allele of TGF-β1 G915C were not associated with the DN risk (GG: OR = 0.84, 95% CI: 0.62-1.14, p = 0.27; CC: OR = 1.05, 95% CI: 0.50-2.22, p = 0.90; C allele: OR = 1.16, 95% CI: 0.88-1.51, p = 0.29). Furthermore, TGF-β1 G800A, C509T gene polymorphism was not associated with the DN risk. In conclusion, TGF-β1 G915C, G800A, and C509T gene polymorphism are not associated with the DN risk. However, more studies should be performed to confirm this relationship in the future.

    Full Text Available Ectrodactyly – ectodermal dysplasia and cleft lip/palate (EEC syndrome (OMIM 604292 is a rare disorder determined by mutations in the TP63 gene. Most cases of EEC syndrome are associated to mutations in the DNA binding domain (DBD region of the p63 protein. Here we report on a three-generation Brazilian family with three individuals (mother, son and grandfather affected by EEC syndrome, determined by a novel mutation c.1037C > G (p.Ala346Gly. The disorder in this family exhibits a broad spectrum of phenotypes: two individuals were personally examined, one presenting the complete constellation of EEC syndrome manifestations and the other presenting an intermediate phenotype; the third affected, a deceased individual not examined personally and referred to by his daughter, exhibited only the split-hand/foot malformation (SHFM. Our findings contribute to elucidate the complex phenotype-genotype correlations in EEC syndrome and other related TP63-mutation syndromes. The possibility of the mutation c.1037C > G being related both to acro-dermato-ungual-lacrimal-tooth (ADULT syndrome and SHFM is also raised by the findings here reported.

    Sepsis is a systemic inflammatory response to infection, accounting for the most common cause of death in intensive care units. Here, we report that peripheral administration of the hypothalamic neuropeptide orexin improves the survival of mice with lipopolysaccharide (LPS) induced endotoxin shock, a well-studied septic shock model. The effect is accompanied by a suppression of excessive cytokine production and an increase of catecholamines and corticosterone. We found that peripherally administered orexin penetrates the blood-brain barrier under endotoxin shock, and that central administration of orexin also suppresses the cytokine production and improves the survival, indicating orexin’s direct action in the central nervous system (CNS). Orexin helps restore body temperature and potentiates cardiovascular function in LPS-injected mice. Pleiotropic modulation of inflammatory response by orexin through the CNS may constitute a novel therapeutic approach for septic shock. DOI: http://dx.doi.org/10.7554/eLife.21055.001 PMID:28035899

  12. Registered nurse-administered sedation for gastrointestinalendoscopic procedure

    Institute of Scientific and Technical Information of China (English)

    2015-01-01

    The rising use of nonanesthesiologist-administeredsedation for gastrointestinal endoscopy has clinicalsignificances. Most endoscopic patients require someforms of sedation and/or anesthesia. The goals ofthis sedation are to guard the patient's safety, minimizephysical discomfort, to control behavior and todiminish psychological responses. Generally, moderatesedation for these procedures has been offered by thenon-anesthesiologist by using benzodiazepines and/oropioids. Anesthesiologists and non-anesthesiologistpersonnel will need to work together for these challengesand for safety of the patients. The sedationtraining courses including clinical skills and knowledgeare necessary for the registered nurses to facilitate thepatient safety and the successful procedure. However,appropriate patient selection and preparation, adequatemonitoring and regular training will ensure that the useof nurse-administered sedation is a feasible and safetechnique for gastrointestinal endoscopic procedures.

    AIM: To assess the efficacy and safety of a balanced approach using midazolam in combination with propofol, administered by non-anesthesiologists, in a large series of diagnostic colonoscopies. METHODS: Consecutive patients undergoing diagnostic colonoscopy were sedated with a single dose of midazolam (0.05 mg/kg) and low-dose propofol (starter bolus of 0.5 mg/kg and repeated boluses of 10 to 20 mg). Induction time and deepest level of sedation, adverse and serious adverse events, as well as recovery times, were prospectively assessed. Cecal intubation and adenoma detection rates were also collected. RESULTS: Overall, 1593 eligible patients were included. The median dose of propofol administered was 70 mg (range: 40-120 mg), and the median dose of midazolam was 2.3 mg (range: 2-4 mg). Median induction time of sedation was 3 min (range: 1-4 min), and median recovery time was 23 min (range: 10-40 min). A moderate level of sedation was achieved in 1561 (98%) patients, whilst a deep sedation occurred in 32 (2%) cases. Transient oxygen desaturation requiring further oxygen supplementation occurred in 8 (0.46%; 95% CI: 0.2%-0.8%) patients. No serious adverse event was observed. Cecal intubation and adenoma detection rates were 93.5% and 23.4% (27.8% for male and 18.5% for female, subjects), respectively. CONCLUSION: A balanced sedation protocol provided a minimalization of the dose of propofol needed to target a moderate sedation for colonoscopy, resulting in a high safety profile for non-anesthesiologist propofol sedation.

    This study investigated the human gastrointestinal uptake (f1) and subsequent whole-body retention of orally administered inorganic radioactive cobalt. Of eight adult volunteers aged between 24 and 68 years, seven were given solutions of (57)Co (T1/2 = 272 d) containing a stable cobalt carrier, and six were given carrier-free (58)Co (T1/2 = 71 d). The administered activities ranged between 25 and 103 kBq. The observed mean f1, based on 6 days accumulated urinary excretion sampling and whole-body counting, was 0.028 ± 0.0048 for carrier-free (58)Co, and 0.016 ± 0.0021 for carrier-associated (57)Co. These values were in reasonable agreement with values reported from previous studies involving a single intake of inorganic cobalt. The time pattern of the total retention (including residual cobalt in the GI tract) included a short-term component with a biological half-time of 0.71 ± 0.03 d (average ± 1 standard error of the mean for the two nuclides), an intermediate component with a mean half-time of 32 ± 8.5 d, and a long-term component (observed in two volunteers) with half-times ranging from 80 to 720 d for the two isotopes. From the present data we conclude that for the short-lived (57)Co and (58)Co, more than 95% of the internal absorbed dose was delivered within 7 days following oral intake, with a high individual variation influenced by the transit time of the unabsorbed cobalt through the gastro-intestinal tract.

  17. Opponent process properties of self-administered cocaine.

    Science.gov (United States)

    Ettenberg, Aaron

    2004-01-01

    Over the past decade, data collected in our laboratory have demonstrated that self-administered cocaine produces Opponent-Process-like behavioral effects. Animals running a straight alley once each day for IV cocaine develop over trials an approach-avoidance conflict about re-entering the goal box. This conflict behavior is characterized by a stop in forward locomotion (usually at the very mouth of the goal box) followed by a turn and 'retreat' back toward the goal box. The results of a series of studies conducted over the past decade collectively suggest that the behavioral ambivalence exemplified by rats running the alley for IV cocaine stems from concurrent and opponent positive (rewarding) and negative (anxiogenic) properties of the drug--both of which are associated with the goal box. These opponent properties of cocaine have been shown to result from temporally distinct affective states. Using a conditioned place preference test, we have been able to demonstrate that while the initial immediate effects of IV cocaine are reinforcing, the state present 15 min post-injection is aversive. In our most recent work, the co-administration of IV cocaine with either oral ethanol or IV heroin was found to greatly diminish the development and occurrence of retreat behaviors in the runway. It may therefore be that the high incidence of co-abuse of cocaine with either ethanol or heroin, stems from the users' motivation to alleviate some of the negative side effects of cocaine. It would seem then that the Opponent Process Theory has provided a useful conceptual framework for the study of the behavioral consequences of self-administered cocaine including the notion that both positive and negative reinforcement mechanisms are involved in the development and maintenance of cocaine abuse.

    Nutrition screening is usually administered by nurses. However, most studies on nutrition screening tools have not used nurses to validate the tools. The 3-Minute Nutrition Screening (3-MinNS) assesses weight loss, dietary intake, and muscle wastage, with the composite score of each used to determine risk of malnutrition. The aim of the study was to determine the validity and reliability of 3-MinNS administered by nurses, who are the intended assessors. In this cross-sectional study, 3 ward-based nurses screened 121 patients aged 21 years and over using 3-MinNS in 3 wards within 24 hours of admission. A dietitian then assessed patients' nutrition status using Subjective Global Assessment within 48 hours of admission, while blinded to the results of the screening. To assess the reliability of 3-MinNS, 37 patients screened by the first nurse were rescreened by a second nurse within 24 hours, who was blinded to the results of the first nurse. The sensitivity, specificity, and best cutoff score for 3-MinNS were determined using the receiver operator characteristics curve. The best cutoff score to identify all patients at risk of malnutrition using 3-MinNS was 3, with sensitivity of 89% and specificity of 88%. This cutoff point also identified all (100%) severely malnourished patients. There was strong correlation between 3-MinNS and SGA (r = .78, P nurses conducting the 3-MinNS tool was 78.3%. The 3-MinNS is a valid and reliable tool for nurses to identify patients at risk of malnutrition.

    In this study, we investigated the effect of ascorbic acid (AA) administration on goat excitability due to transportation. Ten goats administered AA (p.o.) at 100 mg/kg of body weight before transportation served as the experimental group, and seven goats administered only 10 ml/kg of sterile water (p.o.) served as controls. Excitability scores were recorded for each goat; when weighed, before, immediately after, and 3 h after 8 h of transportation. A score of one to four was allocated to each goat; higher scores represent greater excitability. Immediately after transportation, excitability scores decreased significantly, especially those of control goats (p 0.05) different from their pre-transportation normal values, whereas those of control goats were significantly lower (p < 0.01). The correlation i.e. the relationship between excitability score values and percent excitability (percentage of goat with particular excitability score) for different excitability score group 3 h post-transportation was positive and highly significant (p < 0.001), in both experimental and control goats. Our results indicate that road transportation induces considerable stress (depression) in goats as evidenced by a lower excitability score posttransportation. Moreover, the administration of AA pretransportation facilitated the transition from a state of depression to excitation. In conclusion, AA administration to animals prior to transportation may ameliorate the depression often encountered after road transportation.

    Full Text Available Abstract Background To apply clarithromycin as an immunomodulatory treatment in experimental urosepsis by multidrug-resistant Pseudomonas aeruginosa. Methods Acute pyelonephritis was induced in 40 rabbits after inoculation of the test isolate in the renal pelvis. Therapy was administered upon signs of sepsis in four groups: A, controls; B, intravenous clarithromycin; C, amikacin; and D, both agents. Survival and vital signs were recorded; blood was sampled for culture and estimation of pro-inflammatory mediators; monocytes were isolated for determination of apoptotic rate and ex vivo TNFα secretion. Quantitative cultures and biopsies of organs were performed after death. Results Increased rectal temperature and oxygen saturation were found in groups B and D compared to A and C. Mean survival of groups A, B, C and D was 2.65, 7.15, 4.25 and 8.70 days respectively. No differences were noted between groups concerning bacterial load in blood and tissues and serum endotoxins. Serum MDA and total caspase-3 activity of monocytes of group D decreased following treatment compared to other groups. Negative correlation was detected between cytoplasmic caspase-3 and ex vivo secretion of TNFα of blood monocytes of group A; similar correlation was not found for any other group. Pathology scores of liver and lung of group B were lower than group A. Conclusion Clarithromycin administered late in experimental urosepsis by multidrug-resistant P. aeruginosa prolonged survival and ameliorated clinical findings. Its effect is probably attributed to immunomodulatory intervention on blood monocytes.

    AIM:TO determine whether bispectral index (BIS)monitoring is useful for propofol administration for deep sedation during endoscopic retrograde cholangiopancreatography (ERCP).METHODS:Fifty-nine consecutive patients with a variety of reasons for ERCP who underwent the procedure at least twice between 1 July 2010 and 30 November 2010.This was a randomized cross-over study,in which each patient underwent ERCP twice,once with BIS monitoring and once with control monitoring.Whether BIS monitoring was done during the first or second ERCP procedure was random.Patients were intermittently administered a mixed regimen including midazolam,pethidine,and propofol by trained nurses.The nurse used a routine practice to monitor sedation using the Modified Observer's Assessment of Alertness/Sedation (MOAA/S) scale or the BIS monitoring.The total amount of midazolam and propofol used and serious side effects were compared between the BIS and control groups.RESULTS:The mean total propofol dose administered was 53.1 ± 32.2 mg in the BIS group and 54.9± 30.8 mg in the control group (P =0.673).The individual propofol dose received per minute during the ERCP procedure was 2.90 ± 1.83 mg/min in the BIS group and 3.44 ± 2.04 mg in the control group (P =0.103).The median value of the MOAA/S score during the maintenance phase of sedation was comparable for the two groups.The mean BIS values throughout the procedure (from insertion to removal of the endoscope) were 76.5 ± 8.7 for all 59 patients in using the BIS monitor.No significant differences in the frequency of < 80% oxygen saturation,hypotension (< 80 mmHg),or bradycardia (< 50 beats/min) were observed between the two study groups.Four cases of poor cooperation occurred,in which the procedure should be stopped to add the propofol dose.After adding the propofol,the procedure could be conducted successfully (one case in the BIS group,three cases in the control group).The endoscopist rated patient sedation as excellent for

    Full Text Available Abstract Background This study aimed to examine the effects of intermittent and continuous swimming training on muscle protein metabolism in neonatal alloxan-administered rats. Methods Wistar rats were used and divided into six groups: sedentary alloxan (SA, sedentary control (SC, continuous trained alloxan (CA, intermittent trained alloxan (IA, continuous trained control (CC and intermittent trained control (IC. Alloxan (250 mg/kg body weight was injected into newborn rats at 6 days of age. The continuous training protocol consisted of 12 weeks of swimming training in individual cylinder tanks while supporting a load that was 5% of body weight; uninterrupted swimming for 1 h/day, five days a week. The intermittent training protocol consisted of 12 weeks of swimming training in individual cylinder tanks while supporting a load that was 15% of body weight; 30 s of activity interrupted by 30 s of rest for a total of 20 min/day, five days a week. Results At 28 days, the alloxan animals displayed higher glycemia after glucose overload than the control animals. No differences in insulinemia among the groups were detected. At 120 days, no differences in serum albumin and total protein among the groups were observed. Compared to the other groups, DNA concentrations were higher in the alloxan animals that were subjected to continuous training, whereas the DNA/protein ratio was higher in the alloxan animals that were subjected to intermittent training. Conclusion It was concluded that continuous and intermittent training sessions were effective in altering muscle growth by hyperplasia and hypertrophy, respectively, in alloxan-administered animals.

    Full Text Available Regulatory T cells control unwanted immune responses including those that mediate tolerance to self as well as to foreign antigens. Their mechanisms of action include direct and indirect effects on effector T cells and important functions in tissue repair and homeostasis. Regulatory T cells express a number of cell surface markers and transcriptional factors that have been instrumental in defining their origins and potentially their function. A number of immune therapies such as rapamycin, IL-2, as well as anti-T cell antibodies are able to induce regulatory T cells and are being tested for their efficacy in diverse clinical settings with exciting preliminary results. However, a balance exists with the use of some, such as IL-2 that may have effects on unwanted populations as well as promoting expansion and survival of regulatory T cells requiring careful selection of dose for clinical use. The use of cell surface markers has enabled investigators to isolate and expand ex vivo regulatory T cells more than 500-fold routinely. Clinical trials have begun, administering these expanded regulatory T cells to patients as a means of suppressing autoimmune and alloimmune response and potentially inducing immune tolerance. Studies in the future are likely to build on these initial technical achievements and use combinations of agents to improve the survival and functional capacity of regulatory T cells.

    In the last years, casein nanoparticles have been proposed as carriers for the oral delivery of biologically active compounds. However, till now, no information about their possible specific hazards in vivo was available. The aim of this work was to assess the safety of casein nanoparticles when administered orally to animals through a 90 days dose-repeated toxicity study (OECD guideline 408), that was performed in Wistar rats under GLP conditions. After 90 days, no evidences of significant alterations in animals treated daily with 50, 150 or 500 mg/kg bw of nanoparticles were found. This safety agrees well with the fact that nanoparticles were not absorbed and remained within the gut as observed by radiolabelling in the biodistribution study. After 28 days, there was a generalized hyperchloremia in males and females treated with the highest dose of 500 mg/kg bw, that was coupled with hypernatremia in the females. These effects were related to the presence of mannitol which was used as excipient in the formulation of casein nanoparticles. According to these results, the No Observed Adverse Effect Level (NOAEL) could be established in 150 mg/kg bw/day and the Lowest Observed Effect Level (LOEL) could be established in 500 mg/kg bw/day.

    Biorelevant in vitro performance testing of orally administered dosage forms has become an important tool for the assessment of drug product in vivo behavior. An in vitro performance test which mimics the intraluminal performance of an oral dosage form is termed biorelevant. Biorelevant tests have been utilized to decrease the number of in vivo studies required during the drug development process and to mitigate the risk related to in vivo bioequivalence studies. This report reviews the ability of current in vitro performance tests to predict in vivo performance and generate successful in vitro and in vivo correlations for oral dosage forms. It also summarizes efforts to improve the predictability of biorelevant tests. The report is based on the presentations at the 2013 workshop, Biorelevant In Vitro Performance Testing of Orally Administered Dosage Forms, in Washington, DC, sponsored by the FIP Dissolution/Drug Release Focus Group in partnership with the American Association of Pharmaceutical Scientists (AAPS) and a symposium at the AAPS 2012 Annual meeting on the same topic.

    Full Text Available Our previous studies have shown that a lectin rich fraction (TBLF extracted from Tepary bean seeds differentially inhibits cancer cells proliferation in vitro. Before testing the in vivo anticancer effect, the acute and subchronic toxicological assays in rats were conducted, where an oral dose of 50 mg/body weight kg was determined as the NOAEL. This study evaluated the resistance to digestion and complete blood count (CBC after 24 h of the orally administered 50 mg/kg TBLF. The digestion resistance test showed lectins activity retention after 72 h and the CBC study showed a high level of eosinophils, suggesting an allergic-like response. Tolerability was assayed after 6 weeks of treatment by dosing with an intragastric cannula every third day per week. It was observed a transient reduction in food intake and body weight in the first weeks, resulting in body weight gain reduction of 10% respect to the control group at the end of the study. Additionally, organs weight, histopathological analysis and blood markers for nutritional status and for liver, pancreas and renal function were not affected. Our results suggest that 50 mg/kg TBLF administered by oral route, exhibit no toxicity in rats and it was well tolerated. Further studies will focus on long-term studies.

    A mucosal mist formulation of meloxicam, administered as a spray into the mouth (test article), was compared for bioequivalence to a pioneer meloxicam suspension for oral administration (reference article). Pharmacokinetic profiles and average bioequivalence were investigated in 20 dogs. The study design comprised a two-period, two-sequence, two-treatment cross-over design, with maximum concentration (C(max)) and area under plasma concentration-time curve to last sampling time (AUC(last)) used as pivotal bioequivalence variables. Bioequivalence of the products was confirmed, based on relative ratios of geometric mean concentrations (and 90% confidence intervals within the range 0.80-1.25) for C(max) of 101.9 (97.99-106.0) and for AUC(last) of 97.24 (94.44-100.1). The initial absorption of meloxicam was more rapid for the test article, despite virtually identical C(max) values for the two products. Mean elimination half-lives were 29.6 h (test article) and 30.0 h (reference article). The meloxicam plasma concentration-time profiles were considered in relation to published data on the inhibition of the cyclooxygenase-1 (COX-1) and COX-2 isoenzymes by meloxicam.

    This project is currently under contract for research through the Department of Homeland Security until 2011. The group I was responsible for studying has to remain confidential so as not to affect the current project. All dates, reference links and authors, and other distinguishing characteristics of the original group have been removed from this report. All references to the name of this group or the individual splinter groups has been changed to 'Group X'. I have been collecting texts from a variety of sources intended for the use of recruiting and radicalizing members for Group X splinter groups for the purpose of researching the motivation and intent of leaders of those groups and their influence over the likelihood of group radicalization. This work included visiting many Group X websites to find information on splinter group leaders and finding their statements to new and old members. This proved difficult because the splinter groups of Group X are united in beliefs, but differ in public opinion. They are eager to tear each other down, prove their superiority, and yet remain anonymous. After a few weeks of intense searching, a list of eight recruiting texts and eight radicalizing texts from a variety of Group X leaders were compiled.

    OBJECTIVE. Standard benzodiazepine/opioid cocktail has proven inferior to propofol sedation during complicated endoscopic procedures and in low-tolerance patients. Propofol is a short-acting hypnotic with a potential risk of respiratory depression at levels of moderate to deep sedation. The existing literature on capnography for endoscopy patients sedated with nurse-administered propofol sedation (NAPS) is limited. Can the addition of capnography to standard monitoring during endoscopy with NAPS reduce the number, duration, and level of hypoxia. MATERIALS AND METHODS. This study was a randomized controlled trial with an intervention group (capnography) and a control group (without capnography). Eligible subjects were consecutive patients for endoscopy at Gentofte Hospital compliant with the criteria of NAPS. RESULTS. Five hundred and forty patients, 263 with capnography and 277 without capnography, were included in the analysis. The number and total duration of hypoxia was reduced by 39.3% and 21.1% in the intervention group compared to the control group (p > 0.05). No differences in actions taken against insufficient respiration were found. Changes in end-tidal carbon dioxide (R = 0.177, p-value 0.05). Capnography is able to detect insufficient respiration that may lead to hypoxia prior to changes in pulse oximetry. However, due to a limited clinical benefit and additional costs associated with capnography, we do not find capnography necessary during the use of NAPS.

    1. Live body weight gain (WG) and food conversion efficiency (FCE) were measured over a 4-week period in chicks (female, Kabir strain), inoculated intragastrically at one week of age with either a single dose (1 ml) of 10(7) live bacterial cells of Lactobacillus fermentum (LBF) or a strain of Lactobacillus spp. (LB), named Autruche 4 (A4), suspended in 1 ml of phosphate-buffered saline (PBS, pH 7.0); controls (n = 10) were inoculated only with PBS. The same commercial chicken feed was used throughout the 4-week experiment. 2. Compared with the control group, WG to 8 and 21 d, and also liver weight, were significantly greater in LBF and A4 treatments and FCE improved in both of the experimental groups. Compared with the A4 treatment group, WG was significantly higher and FCE improved in the LBF-treated group. The effects of A4 treatment on chicks were similar to those in an earlier pilot experiment using the same methodology but with 1-week-old female chicks (Kabir) inoculated with either the A4 strain or strain of LB named Autruche 5. 3. It is concluded that a single dose of Lactobacillus fermentum or Lactobacillus spp. (Autruche 4) administered intragastrically improves WG and FCE of broiler chicks.

    The PET tracer, {sup 124}I-cG250, directed against carbonic anhydrase IX (CAIX) shows promise for presurgical diagnosis of clear-cell renal cell carcinoma (ccRCC) (Divgi et al. in Lancet Oncol 8:304-310, 2007; Divgi et al. in J Clin Oncol 31:187-194, 2013). The radiometal {sup 89}Zr, however, may offer advantages as a surrogate PET nuclide over {sup 124}I in terms of greater tumor uptake and retention (Rice et al. in Semin Nucl Med 41:265-282, 2011). We have developed a nonlinear immunokinetic model to facilitate a quantitative comparison of absolute uptake and antibody turnover between {sup 124}I-cG250 and {sup 89}Zr-cG250 using a human ccRCC xenograft tumor model in mice. We believe that this unique model better relates quantitative imaging data to the salient biological features of tumor antibody-antigen binding and turnover. We conducted experiments with {sup 89}Zr-cG250 and {sup 124}I-cG250 using a human ccRCC cell line (SK-RC-38) to characterize the binding affinity and internalization kinetics of the two tracers in vitro. Serial PET imaging was performed in mice bearing subcutaneous ccRCC tumors to simultaneously detect and quantify time-dependent tumor uptake in vivo. Using the known specific activities of the two tracers, the equilibrium rates of antibody internalization and turnover in the tumors were derived from the PET images using nonlinear compartmental modeling. The two tracers demonstrated virtually identical tumor cell binding and internalization but showed markedly different retentions in vitro. Superior PET images were obtained using {sup 89}Zr-cG250, owing to the more prolonged trapping of the radiolabel in the tumor and simultaneous washout from normal tissues. Estimates of cG250/CAIX complex turnover were 1.35 - 5.51 x 10{sup 12} molecules per hour per gram of tumor (20 % of receptors internalized per hour), and the ratio of {sup 124}I/{sup 89}Zr atoms released per unit time by tumor was 17.5.

    Children aged 11 to vaccine (LAIV) or placebo, 35+/-7 days apart. Dose 1 was administered concomitantly with a combined measles, mumps, and rubella vaccine (Priorix). Seroresponses to measles and mumps were similar between groups. Compared with placebo, response rates to rubella in LAIV+Priorix recipients were statistically lower at a 15 IU/mL threshold (83.9% vs 78.0%) and the prespecified noninferiority criteria were not met. In a post hoc analysis using an alternate widely accepted threshold of 10 IU/mL, the noninferiority criteria were met (93.4% vs 89.8%). Concomitant administration with Priorix did not affect the overall influenza protection rate of LAIV (78.4% and 63.8% against antigenically similar influenza strains and any strain, respectively).

    The objective of this study was to document the effect of social ranking on the internal exposure of pigs to an antibiotic (fosfomycin) administered either in food or in drinking water. Signs of aggression were recorded at the feeder and drinker. The interindividual variability explained by the social rank was even greater when the test antibiotic was given in food despite the fact that the water consumption was less variable than the food intake. The range of plasma concentrations after administration of fosfomycin either in food or drinking water leads to a number of pigs in the treated group being exposed to rather low and highly variable concentrations of fosfomycin and not able to maintain adequate plasma concentrations above the typical minimum inhibitory concentration (MIC). Social rank clearly influences the level of exposure of pigs to fosfomycin both in food and drinking. However, its administration in drinking water is likely to be the best option to optimize antibiotic efficacy.

    This paper describes the use of participatory design methods in the development of a nurse-administered online patient-provider communication (OPPC) service that is designed to be integrated into routine clinical practice. The OPPC service let patients stay connected with expert nurses and other health care providers to ask questions and receive advice from home. Through focus groups, workshops, heuristic evaluations and usability testing, we identified patients' and clinicians' (nurses' and physicians') user requirements, factors important for successful adoption, implementation and maintenance of the OPPC service, and usability. This paper shares important insights from these participatory design processes that may be helpful for other researchers who wish to implement clinical applications into routine practice.

    The contribution of the polymorphic markers of cytochrome P450 genes to respiratory diseases caused by smoking and occupational factors has been assessed. For this purpose, PCR-RFLP analysis of the CYP1B1 (rs1056836, 4326C > G), CYP2F1 (rs11399890, c.14_15insC), CYP2J2 (rs890293, -76G > T), and CYP2S1 (rs34971233, 13106C > T and rs338583, 13255A > G) gene polymorphisms has been performed. The analysis has shown that the polymorphic variants of the CYP1B1 (rs1056836, 4326C > G) and CYP2F1 (rs11399890, c. 14_15insC) genes may contribute to the development of occupational chronic bronchitis. The proportion of CYP1B1* 1*3 heterozygotes in the group of patients with occupational chronic bronchitis is considerably greater than in the group of healthy workers (69.16% versus 53.29%; chi2 = 5.94, P = 0.02, P(cor) = 0.04, OR = 1.97, the 95% CI is 1.13-3.42). Patients with occupational chronic bronchitis and healthy workers significantly differed from each other in the frequency distribution of the genotypes ofthe CYP2F1 (rs11399890, c.14_15insC) polymorphic marker (chi2 = 6.18, d.f = 2, P = 0.05). The frequency of the wild type/ins heterozygous genotype for the CYP2F1 gene is higher in healthy workers (36.08%) than in patients (22.22%) (chi2 = 5.48, P = 0.02, P(cor) = 0.04, OR = 0.51, the 95% CI is 0.28-0.90). No association has been found between the CYP2J2 (rs890293, -76G > T) or CYP2S1 (rs34971233, 13106C > T, P466L and rs338583, 13255A > G) gene polymorphisms and respiratory diseases.

    Gowers in his paper on quasirandom groups studies a question of Babai and Sos asking whether there exists a constant $c > 0$ such that every finite group $G$ has a product-free subset of size at least $c|G|$. Answering the question negatively, he proves that for sufficiently large prime $p$, the group $\\mathrm{PSL}_2(\\mathbb{F}_p)$ has no product-free subset of size $cn^{8/9}$, where $n$ is the order of $\\mathrm{PSL}_2(\\mathbb{F}_p)$. We will consider the problem for compact groups and in particular for profinite groups $\\SL_k(\\ZZ_p)$ obtain lower and upper exponential bounds for the supremal measure of the product-free sets. The proof involves establishing a lower bound for the dimension of non-trivial representations of the finite groups $\\SL_k(\\Z{p^n})$.

    Exposure to the drinking water contaminant arsenate is a daily occurrence and there are concerns that this exposure may lead to cancer. Although the acute dispositional effects of arsenate have been studied in detail, there is minimal information on the disposition and toxicological effects of it after continuous exposure. The objective of this study was to examine in mice the effect of a 4-wk treatment with arsenate administered in drinking water. Female B6C3F1 mice (3/cage) were housed in metabolism cages and given water and food ad libitum. Two groups (A, B) of mice were treated (4 cages/treatment/group) with distilled water (control, C) or water containing 0.025 mg/L (L) or 2.5 mg/L (H) arsenate. Group A was sacrificed on d 28 and plasma and urine samples were taken for determination of clinical chemistry parameters. Liver and kidney tissue samples were taken for histopathological analysis. The reduced nonprotein sulfhydryl (NPSH) content in several tissues was determined. Group B was gavaged with [73As]arsenate on d 28 and continued the arsenate drinking water exposure for 48 h. Excreta and tissues were collected and analyzed for 73As. Urine was further analyzed for arsenate and its metabolites. There were no effects on the mean daily amount of water and food consumed, whereas the mean daily urine volume excreted was significantly elevated by 10% in the H-treated animals compared to C and L. A dose-related hepatic vacuolar degeneration in the liver was observed, but no histological changes were evident in the kidney. Only clinical chemistry parameters in plasma were altered by the arsenate treatment. Glucose was significantly lower at the H dose compared to C and L, triglycerides were significantly greater in C than L and H, and creatinine was significantly greater in H than C. Hepatic NPSH content in the H animals was significantly lower than C and L animals, whereas no effects in lung and kidney were detected. The weights of liver, lung, and kidney, as well

    Full Text Available Abstract A female patient, with normal familial history, developed at the age of 30 months an episode of diarrhoea, vomiting and lethargy which resolved spontaneously. At the age of 3 years, the patient re-iterated vomiting, was sub-febrile and hypoglycemic, fell into coma, developed seizures and sequels involving right hemi-body. Urinary excretion of hexanoylglycine and suberylglycine was low during this metabolic decompensation. A study of pre- and post-prandial blood glucose and ketones over a period of 24 hours showed a normal glycaemic cycle but a failure to form ketones after 12 hours fasting, suggesting a mitochondrial β-oxidation defect. Total blood carnitine was lowered with unesterified carnitine being half of the lowest control value. A diagnosis of mild MCAD deficiency (MCADD was based on rates of 1-14C-octanoate and 9, 10-3H-myristate oxidation and of octanoyl-CoA dehydrogenase being reduced to 25% of control values. Other mitochondrial fatty acid oxidation proteins were functionally normal. De novo acylcarnitine synthesis in whole blood samples incubated with deuterated palmitate was also typical of MCADD. Genetic studies showed that the patient was compound heterozygous with a sequence variation in both of the two ACADM alleles; one had the common c.985A>G mutation and the other had a novel c.145C>G mutation. This is the first report for the ACADM gene c.145C>G mutation: it is located in exon 3 and causes a replacement of glutamine to glutamate at position 24 of the mature protein (Q24E. Associated with heterozygosity for c.985A>G mutation, this mutation is responsible for a mild MCADD phenotype along with a clinical story corroborating the emerging literature view that patients with genotypes representing mild MCADD (high residual enzyme activity and low urinary levels of glycine conjugates, similar to some of the mild MCADDs detected by MS/MS newborn screening, may be at risk for disease presentation.

    Full Text Available Iron overload is associated with acquired and genetic conditions, the most common being hereditary hemochromatosis (HH type-I, caused by HFE mutations. Here, we conducted a hospital-based case-control study of 41 patients from the São Miguel Island (Azores, Portugal, six belonging to a family with HH type-I pseudodominant inheritance, and 35 unrelated individuals fulfilling the biochemical criteria of iron overload compatible with HH type-I. For this purpose, we analyzed the most common HFE mutations- c.845G>A [p.Cys282Tyr], c.187C>G [p.His63Asp], and c.193A>T [p.Ser65Cys]. Results revealed that the family's HH pseudodominant pattern is due to consanguineous marriage of HFE-c.845G>A carriers, and to marriage with a genetically unrelated spouse that is a -c.187G carrier. Regarding unrelated patients, six were homozygous for c.845A, and three were c.845A/c.187G compound heterozygous. We then performed sequencing of HFE exons 2, 4, 5 and their intron-flanking regions. No other mutations were observed, but we identified the -c.340+4C [IVS2+4C] splice variant in 26 (74.3% patients. Functionally, the c.340+4C may generate alternative splicing by HFE exon 2 skipping and consequently, a protein missing the α1-domain essential for HFE/ transferrin receptor-1 interactions. Finally, we investigated HFE mutations configuration with iron overload by determining haplotypes and genotypic profiles. Results evidenced that carriers of HFE-c.187G allele also carry -c.340+4C, suggesting in-cis configuration. This data is corroborated by the association analysis where carriers of the complex allele HFE-c.[187C>G;340+4T>C] have an increased iron overload risk (RR = 2.08, 95% CI = 1.40-2.94, pG;340+4T>C] has a role, as genetic predisposition factor, on iron overload in the São Miguel population. Independent replication studies in other populations are needed to confirm this association.

    Dental treatment of intellectually disabled patients is frequently performed under general anesthesia or sedation. Many of these patients have epilepsy and are medicated with antiepileptic drugs (AEDs). Carbamazepine (CBZ) and phenytoin (PHT) are known to promote the metabolism of midazolam, and the blood levels of midazolam in patients medicated with CBZ or PHT may be different from those in healthy individuals. In this study, we clarified the influences of CBZ and PHT on the blood level of intravenously administered midazolam in patients medicated with CBZ or PHT. The subjects were divided into the following groups: not medicated with AEDs (control group), medicated with only CBZ or PHT (mono CBZ/PHT group), and medicated with CBZ or PHT or both and other AEDs (poly CBZ/PHT group). General anesthesia was achieved using midazolam, propofol, and remifentanil, and then the blood midazolam level was measured at 10, 30, and 60 min after intravenous midazolam administration. According to the results, the blood midazolam level was significantly lower in the mono and poly CBZ/PHT groups than in the control group. This finding suggests that intravenously administered midazolam may have a weaker effect in patients medicated with CBZ or PHT.

    Full Text Available The objective of this study was to determine the effect of orally administered Enterococcus faecium EF1 on intestinal cytokines and chemokines production in piglets. Twenty-four newborn piglets were randomly divided into two groups. The treatment group (T1, orally administered sterilized (110 ºC for 30 min skim milk 10% (2 ml/piglet/day with addition of viable E. faecium EF1 (5~6×108 cfu/ml on 1st, 3rd and 5th day after birth. The control group (T0, were fed the same volume of sterilized skim milk without addition of probiotics. Feeding trial was conducted for 25 days of suckling age. At the end of trail six piglets were randomly selected from each group to collect the samples of jejunum and ileum mucosa to observe the cytokines and chemokines production. The results showed that concentrations of IL-10 and TGF-β1 significantly increased in T1 group. Whereas, production of IL-1β, IL-6, IL-12, IFN-γ and IL-8 decreased in T1 compared to T0. Levels of TNF-α were increased in jejunal mucosa, while decreased in ileal mucosa comparatively in T1 group. Our findings revealed that oral administration of E. faecium EF1 induced a strong anti-inflammatory response in the small intestine. These immunomodulatory effects of this bacterium might contribute to maintenance of immune homeostasis in the intestine of piglets.

    Comparison of tramadol, tramadol-metamizol and tramadol-lornoxicam administered by intravenous PCA in management of postoperative pain. The aim of the present study was to compare of the postoperative analgesic effects of tramadol, combinations of tramadol-metamizol and tramadol-lornoxicam administered by intravenous Patient Control Analgesia (PCA) in lower abdominal surgery. Sixty adult, female patients who undergoing lower abdominal surgery, were included in this study. Patients were randomized to three groups. The solutions were prepared containing 500 mg tramadol in 50 ml saline (10 mg/ml tramadol) for Group I, 250 mg tramadol+3000 mg metamizol in 50 ml saline (5 mg/ml tramadol+60 mg/ml metamizol) for Group II and 250 mg tramadol+20 mg lornoxicam in 50 ml saline (5mg/ml tramadol + 0.4 mg/ml lornoxicam) for Group III. Loading dose 10 ml was administrated within 30 min 30 to 40 min before the end of the surgery. PCA was started at the first complaint of pain. Pain was evaluated by VAS in every 15 minute intervals at the first hour and later at 2nd, 4th, 8th, 12th, 18th and 24th hours postoperatively. Vital parameters, side-effects, sedation scores and total analgesic consumptions were also recorded concurrently. Total tramadol and anti-emetic consumption, the incidence of postoperative nausea and vomiting (PONV) were significantly higher in group I than the other groups (pmetamizol and tramadol-lornoxicam combinations administered by intravenous PCA provide efficient postoperative analgesia with less side effects.

    Full Text Available Background and Aims: Mixing adjuvants with hyperbaric bupivacaine in a single syringe before injecting the drugs intrathecally is an age old practice. In doing so, the density of the hyperbaric solution and also of the adjuvant drugs may be altered, thus affecting the spread of drugs. Administering local anaesthetic and the adjuvants separately may minimise the effect of the changes in densities. We aimed to compare block characteristics, intraoperative haemodynamics and post-operative pain relief in parturients undergoing caesarean section (CS after administering hyperbaric bupivacaine and clonidine intrathecally as a mixture and sequentially. Methods: In this single-blind prospective randomised controlled study at a tertiary care centre from 2010 to 12, 60 full-term parturients scheduled for elective CSs were divided into two groups on the basis of technique of intrathecal drug administration. Group M received mixture of clonidine (75 mcg and hyperbaric bupivacaine 0.5% (10 mg intrathecally, whereas Group B received clonidine (75 mcg followed by hyperbaric bupivacaine 0.5% (10 mg through separate syringes. Observational descriptive statistics, analysis of variance test, Wilcoxon test and Chi-square test were used as applicable. Results: Duration of analgesia was significantly longer in Group B (474.33 ± 20.79 min in which the drug was given sequentially than in Group M (337 ± 18.22 min. Furthermore, the time to achieve highest sensory block and complete motor block was significantly less in Group B without any major haemodynamic instability and neonatal outcome. Conclusions: When clonidine and hyperbaric bupivacaine were administered in a sequential manner, block characteristics improved significantly compared to the administration of the mixture of the two drugs.

    Hypotension occurs during cardiopulmonary bypass (CPB), in part because of induction of the inflammatory response, for which nitric oxide and guanylate cyclase play a central role. In this study we examined the hemodynamic effects of methylene blue (MB), an inhibitor of guanylate cyclase, administered during cardiopulmonary bypass (CPB) to patients taking angiotensin-converting enzyme inhibitors. Thirty patients undergoing cardiac surgery were randomized to receive either MB (3 mg/kg) or saline (S) after institution of CPB and cardioplegic arrest. CPB was managed similarly for all study patients. Hemodynamic data were assessed before, during, and after CPB. The use of vasopressors was recorded. All study patients experienced a similar reduction in mean arterial blood pressure (MAP) and systemic vascular resistance (SVR) with the onset of CPB and cardioplegic arrest. MB increased MAP and SVR and this effect lasted for 40 minutes. The saline group demonstrated a persistently reduced MAP and SVR throughout CPB. The saline group received phenylephrine more frequently during CPB, and more norepinephrine after CPB to maintain a desirable MAP. The MB group recorded significantly lower serum lactate levels despite equal or greater MAP and SVR. In conclusion, administration of MB after institution of CPB for patients taking angiotensin-converting enzyme inhibitors increased MAP and SVR and reduced the need for vasopressors. Furthermore, serum lactate levels were lower in MB patients, suggesting more favorable tissue perfusion.

    Considering the negative effects of glucocorticoid treatment, especially during fetal development it is important to investigate effectors decreasing such disadvantages. The aim of this study was to investigate the effect of prenatally administered dexamethasone (Dex), a synthetic glucocorticoid, on the histomorphometry of the femur in the offspring of spiny mice. The study was performed on 24 pregnant spiny mice. The time of the experiment included the prenatal period between the 20th day of gestation until birth (pregnancy lasts on average of 36-38 days). The mice from the experimental group received dexamethasone per os in a dose of 125 mg/kg birth weight daily. At the end, the newborns from the experimental and control group were weighted and euthanized. Maternal Dex treatment resulted in a 17% decrease in birth weight in newborns. Dex administration significantly reduced the thickness of the hypertrophy zone of the growth plate by 34% and total thickness by 8,7%. In addition, Dex decreased the number of cells in the articular cartilage by 27% and significantly decreased their diameter by 5%. Dex also affected the structure and spatial distribution of thick and thin collagen fibers, lowering the proportion of thin fibers compared with the control group. Moreover, Dex treatment considerably lowered the amount of proteoglycans in articular and growth cartilages. Exposure to glucocorticoids in pregnant spiny mice affects cartilage development by accelerating maturity of collagen fibers and growth plate, presumably along with further disruption of longitudinal growth of long bones.

    Full Text Available Introduction & Objective: Onset of action of relaxants is influenced by cardiac output and muscle blood flow. Ephedrine increases blood flow to muscles and may shorten the onset of action of succinylcholine. The aim of this study was to evaluate the effect of small-dose of ephedrine administered prior to rapid-sequence induction of anesthesia on the onset time of succinylcholine for endotracheal intubation. Materials & Methods: In this randomized clinical trial, 60 patients scheduled for elective gynecologic surgeries in Alzahra hospital in Tabriz 1385, were selected. In these patients ephedrine, 70 µg/kg (study group, n=30, or saline (placebo group, n=30 was administered 3 minutes before induction of anesthesia with thiopentone/fentanyl. Succinylcholine, 0.6 mg/kg, was administrated to facilitate the tracheal intubation. Onset of succinylcholine, intubating conditions and hemodynamic variables were recorded in the subjects. Results: Fasciculation was absent in 60% (36 of the patients. No significant differences were found between the onsets of fasciculation between two groups. Moreover, the difference in duration of fasciculation in two groups was not significant. Onset time of succinylcholine was significantly shorter in study group (19.53±3.91 second, compared with placebo group (25.87±7.11 second (p<0.0001. Patients in study group were intubated in 47.07±4.51 seconds compared with 58.73±9.04 seconds in placebo group (p<0.0001. Intubation conditions were similar in both groups. Heart rate was slightly increased in study patients in the first and 3rd minutes after ephedrine administration, but there was no significant difference in systolic blood pressure values compared with the baseline value between two groups. Conclusion: The onset time of succinylcholine is shortened with small-dose of ephedrine pretreatment without significant adverse heamodynamic effects.

    Full Text Available Agmatine, an endogenous polyamine and putative neuromodulator, is known to have neuroprotective effects on various neurons in the central nervous system. We determined whether or not topically administered agmatine could reduce ischemic retinal injury. Transient ocular ischemia was achieved by intraluminal occlusion of the middle cerebral artery of ddY mice (30-35 g for 2 h, which is known to also induce occlusion of the ophthalmic artery. In the agmatine group (N = 6, a 1.0 mM agmatine-containing ophthalmic solution was administered four times daily for 2 weeks before occlusion. In the control group (N = 6, a 0.1% hyaluronic acid ophthalmic solution was instilled at the same times. At 22 h after reperfusion, the eyeballs were enucleated and the retinal sections were stained by terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL. Transient ocular ischemia induced apoptosis of retinal cells in the entire retinal layer, and topically administered agmatine can significantly reduce this ischemic retinal injury. The proportion of apoptotic cells was definitely decreased (P < 0.001; Kruskal-Wallis test. Overall, we determined that topical agmatine application effectively decreases retinal damage in an in vivo ocular ischemic injury model. This implies that agmatine is a good candidate as a direct neuroprotective agent for eyes with ocular ischemic diseases.

    Full Text Available BACKGROUND: With a wide range of applications, titanium dioxide (TiO₂ nanoparticles (NPs are manufactured worldwide in large quantities. Recently, in the field of nanomedicine, intravenous injection of TiO₂ nanoparticulate carriers directly into the bloodstream has raised public concerns on their toxicity to humans. METHODS: In this study, mice were injected intravenously with a single dose of TiO₂ NPs at varying dose levels (0, 140, 300, 645, or 1387 mg/kg. Animal mortality, blood biochemistry, hematology, genotoxicity and histopathology were investigated 14 days after treatment. RESULTS: Death of mice in the highest dose (1387 mg/kg group was observed at day two after TiO₂ NPs injection. At day 7, acute toxicity symptoms, such as decreased physical activity and decreased intake of food and water, were observed in the highest dose group. Hematological analysis and the micronucleus test showed no significant acute hematological or genetic toxicity except an increase in the white blood cell (WBC count among mice 645 mg/kg dose group. However, the spleen of the mice showed significantly higher tissue weight/body weight (BW coefficients, and lower liver and kidney coefficients in the TiO₂ NPs treated mice compared to control. The biochemical parameters and histological tissue sections indicated that TiO₂ NPs treatment could induce different degrees of damage in the brain, lung, spleen, liver and kidneys. However, no pathological effects were observed in the heart in TiO₂ NPs treated mice. CONCLUSIONS: Intravenous injection of TiO₂ NPs at high doses in mice could cause acute toxicity effects in the brain, lung, spleen, liver, and kidney. No significant hematological or genetic toxicity was observed.

    Characterizing the variability in transcript levels across breeds and sex in swine for genes that play a role in drug metabolism may shed light on breed and sex differences in drug metabolism. The objective of the study is to determine if there is heterogeneity between swine breeds and sex in transcript levels for genes previously shown to play a role in drug metabolism for animals administered flunixin meglumine or fenbendazole. Crossbred nursery female and castrated male pigs (n = 169) spread across 5 groups were utilized. Sires (n = 15) of the pigs were purebred Duroc, Landrace, Yorkshire or Hampshire boars mated to a common sow population. Animals were randomly placed into the following treatments: no drug (control), flunixin meglumine, or fenbendazole. One hour after the second dosing, animals were sacrificed and liver samples collected. Quantitative Real-Time PCR was used to measure liver gene expression of the following genes: SULT1A1, ABCB1, CYP1A2, CYP2E1, CYP3A22 and CYP3A29. The control animals were used to investigate baseline transcript level differences across breed and sex. Post drug administration transcript differences across breed and sex were investigated by comparing animals administered the drug to the controls. Contrasts to determine fold change were constructed from a model that included fixed and random effects within each drug. Significant (P-value fenbendazole, respectively. The current analysis found transcript level differences across swine breeds and sex for multiple genes, which provides greater insight into the relationship between flunixin meglumine and fenbendazole and known drug metabolizing genes.

    The aetiology and treatment options for idiopathic granulomatous mastitis (IGM) are controversial. The aim was to study the clinical and diagnostic features and discuss medical and surgical treatment for IGM in our patients. Sixty-five patients who met the histological criteria for IGM were retrospectively studied. The diagnosis of IGM was confirmed using Mammotome (an ultrasound-guided, vacuum-assisted biopsy system), core needle biopsy, quadrantectomy or segmental resection. Forty-five patients were treated with prednisolone (69.2%). Immunohistochemical (IHC) staining for immune-related antigens (CD3, CD4, CD8, CD79a, IgG, and IgM) was performed. Ultrasonography (USG) was carried out in all patients. Among them, 61 were considered to have an inflammatory mass and 15 had accompanying liquefaction. In four patients, the findings mimicked breast carcinoma (6.2%). The IHC results showed CD3, CD4, CD8 and CD79a lymphocytes diffusely distributed in the lesion. Stains for IgG and IgM were negative. Prednisolone was administered to the patients diagnosed with IGM. The success rate was 53 (81.5%) and the whole recurrence was 12 (18.5%). The median follow-up period was 12 months (range 4-42 months). The aetiology of IGM remains uncertain. The disease has no propensity for the right or left breast. It is a local autoimmune disease, involving humoral and cell-mediated immunity. Hyperprolactinaemia may play a role in some patients. Corticosteroids administered after complete removal of the IGM lesion using the Mammotome biopsy system is an effective treatment option. Published by the BMJ Publishing Group Limited.

    The efficacy of orally administered afoxolaner against adult dog fleas, Ctenocephalides canis, was evaluated in a controlled, blinded study. A total of 32 dogs were infested with 100 adult unfed fleas approximately 24h prior to treatment and then at weekly intervals for 5 weeks after treatment. Live fleas were counted upon removal at 12h (for 16 dogs) and 24h (for the remaining 16 dogs) after treatment (for counts performed the first week) or after infestation (for counts performed on subsequent weeks). In addition, flea eggs were collected from each pen and counted for the dogs with flea removal at 24h. Dosing of individual dogs was achieved using a combination of the chewable tablets to be as close as possible to the minimum effective dose of 2.5mg/kg. The percent efficacy of the afoxolaner treatment was ≥ 99.0% for all 24-h flea counts. For flea counts performed 12h after treatment or infestations, the percent efficacy was ≥ 94.1% up to Day 21. After Day 1, no flea eggs were recovered from the afoxolaner treated group, providing 100% reduction in numbers of flea eggs recovered versus untreated control group. This study confirmed that a single oral treatment with afoxolaner provided excellent efficacy against infestations by C. canis within 12-24h after treatment, prevented re-infestations, and completely prevented egg production from new flea infestations for up to 5 weeks.

    Social fears and worries in children are common and impairing. Yet, questions have been raised over the efficacy, suitability and accessibility of current frontline treatments. Here, we present data on the effectiveness of a novel parent-administered Cognitive Bias Modification of Interpretations (CBM-I) training tool. CBM-I capitalises on findings demonstrating an association between anxiety symptoms and biased interpretations, the tendency to interpret ambiguous situations negatively. Through CBM-I training, participants are exposed to benign resolutions, and reinforced for selecting these. In adults and adolescents, CBM-I training is effective at reducing symptoms and mood reactivity. In the present study, we developed a novel, child-appropriate form of CBM-I training, by presenting training materials within bedtime stories, read by a parent to the child across three consecutive evenings. Compared to a test-retest control group (n = 17), children receiving CBM-I (n = 19) reported greater endorsement of benign interpretations of ambiguous situations post-training (compared to pre-training). These participants (but not the test-retest control group) also showed a significant reduction in social anxiety symptoms. Pending replication and extensions to a clinical sample, these data may implicate a cost-effective, mechanism-driven and developmentally-appropriate resource for targeting social anxiety problems in children.

    The aim of this study was to determine the effects of estrogen therapy (ET) on carotid artery inflammation when initiated early and late relative to surgical menopause. Female cynomolgus macaques consuming atherogenic diets were ovariectomized and randomized to control or oral estradiol (E2; human equivalent dose of 1 mg/d micronized E2) initiated at 1 month (early menopause, n = 24) or 54 months (late menopause, n = 40) after ovariectomy. The treatment period was 8 months. Carotid artery expression of the markers of monocyte/macrophages (CD68 and CD163), dendritic cells (CD83), natural killer cells (neural cell adhesion molecule-1), and interferon-γ was significantly lower in E2-treated animals in the early menopause group but not in the late menopause group (P menopausal stage (P menopause inhibits macrophage accumulation in the carotid artery, an effect that is not observed when E2 is administered after several years of estrogen deficiency. No evidence for pro-inflammatory effects of late ET is observed. The results provide support for the timing hypothesis of postmenopausal ET with implications for the interpretation of outcomes in the Women's Health Initiative.

    2015-01-01

    Written by one of the subject’s foremost experts, this book focuses on the central developments and modern methods of the advanced theory of abelian groups, while remaining accessible, as an introduction and reference, to the non-specialist. It provides a coherent source for results scattered throughout the research literature with lots of new proofs. The presentation highlights major trends that have radically changed the modern character of the subject, in particular, the use of homological methods in the structure theory of various classes of abelian groups, and the use of advanced set-theoretical methods in the study of undecidability problems. The treatment of the latter trend includes Shelah’s seminal work on the undecidability in ZFC of Whitehead’s Problem; while the treatment of the former trend includes an extensive (but non-exhaustive) study of p-groups, torsion-free groups, mixed groups, and important classes of groups arising from ring theory. To prepare the reader to tackle these topics, th...

    D.C. Mohr (1995) suggested that high deterioration rates may occur in self-directed treatments. The investigators examined data from 5 studies of self-administered treatment for depression and found in contrast much lower rates (9% vs. 19%) than those cited in Mohr's review. The negative response rates for the self-administered treatments compared favorably with the negative response rates in the therapist-administered treatments provided in the National Institute of Mental Health Treatment of Depression Collaborative Research Program. The findings indicate that it may be the manner in which participants are prepared for self-administered treatment that is critical.

    Full Text Available Objective: To investigate the effects of coconut water intake on lipid profile and atherogenic predictor indices of albino rabbits overdosed with paracetamol using standard methods. Methods: Thirty-five albino rabbits weighing between 800–1200 g and aged between 2 and 3 months, were divided into 7 groups (I–VII of 5 animals each. Groups I, II and III were orally administered distilled water (20 mL/kg body weight, coconut water (20 mL/kg body weight and paracetamol (1000 mg/kg body weight respectively, for 7 days. Groups IV and V were administered coconut water (20 mL/kg body weight and silymarin (35 mg/kg body weight, respectively, for 6 days, then paracetamol (1000 mg/kg body weight on the 7th day. Groups VI and VII were administered distilled water for 6 days, paracetamol on the 7th day, then coconut water and silymarin, respectively, after 3 h. Results: The results showed that paracetamol overdose significantly reduced (P < 0.05 the mean body weight of the animals, increased the concentrations of serum total cholesterol, triacylglycerol, very low density lipoprotein cholesterol, low density lipoprotein cholesterol and the atherogenic predictor indices but reduced the serum high density lipoprotein cholesterol concentration of the animals relative to the control. The observed changes in the lipid profile and atherogenic predictor indices were countered more by post- than pre-treatment with coconut water and silymarin. Conclusions: The results indicated that coconut water acted as an effective antidote to paracetamol overdose-induced lipid abnormality in animals.

    To investigate the safety of gossypol in small doses, electrocardiograms (EKG) of 30 healthy male voluteers were traced at the 4th, 12th, 36th and 52th weeks after administration of the drug. The dosage regimen was gossypol acetic acid, 15 mg per day, for the first 12 weeks (induction phase), followed by 10 mg or 7. 5 mg for the rest 40 weeks (effective phase ). Twelve voluteers were withdrawn due to hypokalemia, normal spermatogenesis in the effective phase or others before the 52thweek. Wave form of all EKGs (96 groups obtained in the period) .was normal. However, compared with EKG made before gossypol administration, in most cases the average of PR interval became longer and the average of QRS duration shorter. Subjects with PR interval prolongation, in the whole observation period, were more than those with PR interval reduction. Thea lteration of PR interval at the 4th and 12th week was statistically significant (P<0. 05). The results were difficult to be explained with effect of gossypol on potassium metabolism. More extensive research is necessary to use gossypol, as a polyphenolie aldehyde compound for any clinical object.

    Nicolau CONTE NETO

    Full Text Available Abstract The main objective of this study was to cause bisphosphonate-related osteonecrosis of the jaws to develop in a rodent model. Adult male Holtzman rats were assigned to one of two experimental groups to receive alendronate (AL; 1 mg/kg/week; n = 6 or saline solution (CTL; n = 6. After 60 days of drug therapy, all animals were subjected to first lower molar extraction, and 28 days later, animals were euthanized. All rats treated with alendronate developed osteonecrosis, presenting as ulcers and necrotic bone, associated with a significant infection process, especially at the inter-alveolar septum area and crestal regions. The degree of vascularization, the levels of C-telopeptide cross-linked collagen type I and bone-specific alkaline phosphatase, as well as the bone volume were significantly reduced in these animals. Furthermore, on radiographic analysis, animals treated with alendronate presented evident sclerosis of the lamina dura of the lower first molar alveolar socket associated with decreased radiographic density in this area. These findings indicate that the protocol developed in the present study opens new perspectives and could be a good starting model for future property design.

    Ferric pyrophosphate citrate (FPC) is a water-soluble iron salt administered via dialysate to supply iron directly to transferrin. The PRIME study tested whether treatment with FPC could reduce prescribed erythropoiesis-stimulating agent (ESA) use and maintain hemoglobin in hemodialysis patients. This 9-month, randomized, placebo-controlled, double-blind, multicenter clinical study included 103 patients undergoing hemodialysis 3–4 times weekly. The FPC group received dialysate containing 2 μmol/l of iron. The placebo group received standard dialysate. A blinded central anemia management group facilitated ESA dose adjustments. Intravenous iron was administered according to the approved indication when ferritin levels fell below 200 μg/l. The primary end point was the percentage change from baseline in prescribed ESA dose at end of treatment. Secondary end points included intravenous iron use and safety. At the end of treatment, there was a significant 35% reduction in prescribed ESA dose in FPC-treated patients compared with placebo. The FPC patients used 51% less intravenous iron than placebo. Adverse and serious adverse events were similar in both groups. Thus, FPC delivered via dialysate significantly reduces the prescribed ESA dose and the amount of intravenous iron needed to maintain hemoglobin in chronic hemodialysis patients. PMID:26154926

    We aimed to characterize the lipidomic, metabolomic, and transcriptomic profiles in preterm piglets administered enteral (ENT) formula or three parenteral lipid emulsions [parenteral nutrition (PN)], Intralipid (IL), Omegaven (OV), or SMOFlipid (SL), for 14 days. Piglets in all parenteral lipid groups showed differential organ growth versus ENT piglets; whole body growth rate was lowest in IL piglets, yet there were no differences in either energy expenditure or (13)C-palmitate oxidation. Plasma homeostatic model assessment of insulin resistance demonstrated insulin resistance in IL, but not OV or SL, compared with ENT. The fatty acid and acyl-CoA content of the liver, muscle, brain, and plasma fatty acids reflected the composition of the dietary lipids administered. Free carnitine and acylcarnitine (ACT) levels were markedly reduced in the PN groups compared with ENT piglets. Genes associated with oxidative stress and inflammation were increased, whereas those associated with alternative pathways of fatty acid oxidation were decreased in all PN groups. Our results show that new generation lipid emulsions directly enrich tissue fatty acids, especially in the brain, and lead to improved growth and insulin sensitivity compared with a soybean lipid emulsion. In all total PN groups, carnitine levels are limiting to the formation of ACTs and gene expression reflects the stress of excess lipid on liver function.

    The primary objective of this study was to assess the effect of aromatherapy and classic massage administered in various ways to breast cancer patients on their symptoms and quality of life. The sampling consisted of 280 patients. Quality of life and symptoms of the patients were evaluated once at baseline and then at week 6 and week 10 following the intervention. After intervention, the control group was observed to have lower total quality of life score and subdomain scores, whereas fragrance, massage and aromatherapy massage groups had higher scores, and the increase was more obvious particularly in the patients in the aromatherapy massage group. Similarly, whereas psychological and physical symptoms were experienced more intensely in the control group, the severity of all the symptoms experienced by the other patients decreased at week 6 and week 10 as compared with baseline especially in the group that was administered massage with aromatherapy.

    It has been asserted that consumption of dietary cholesterol (Chol) raises atherosclerotic cardiovascular diseases and that Chol causes an increase in free radical production. Hypercholesterolemic diet has also been reported to cause changes in the antioxidant system. In our study, different doses of Juniperus communis Linn (JCL) oil, a tree species growing in Mediterranean and Isparta regions and having aromatic characteristics, were administered to rats; and the levels of antioxidant enzymes superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT), and thiobarbituric acid reactive substances assay (TBARS) were examined in the heart tissue of rats. In this study, 35 Wistar Albino male adult rats weighing approximately 250-300 g were used. The rats were divided into five groups of seven each. The control group was administered normal pellet chow, and the Chol group was administered pellet chow including 2% Chol, while 50 JCL, 100 JCL, and 200 JCL groups were administered 50, 100, and 200 mg/kg JCL oil dissolved in 0.5% sodium carboxy methyl cellulose, respectively, in addition to the pellet chow containing 2% Chol, by gavage. After 30 days, the experiment was terminated and the antioxidant enzyme activities were examined in the heart tissue of rats. While consumption of dietary Chol decreases the activities of SOD, GSH-Px, and CAT in heart tissue of rats (not significant), administeration of 200 mg/kg JCL oil in addition to Chol led to a significant increase in the activity of antioxidant enzymes. Administering Chol led to a significant increase in TBARS level. Administering 100 and 200 mg/kg JCL oil together with Chol prevented significantly the increase in lipid peroxides. As a result of the study, JCL oil showed oxidant-antioxidant effect in the heart tissue of rats. © The Author(s) 2012.

    Prulifloxacin, a fluoroquinolone antibacterial agent, may be a useful addition to the antimicrobial armamentarium against prostatitis once the ability of its active metabolite, ulifloxacin, to penetrate prostatic tissue has been determined. This study set out to evaluate ulifloxacin penetration into the prostate following administration of the oral fluoroquinolone prodrug prulifloxacin in patients undergoing transurethral resection of the prostate (TURP). This was a phase I, randomized, open-label, single-centre study involving 20 male Caucasian patients (mean age 63.1 years) requiring TURP for treatment of benign prostatic hyperplasia. Sixteen patients were randomized to receive prulifloxacin; the other four patients were not treated (controls) in order to validate the bioanalytical method. Patients in the active treatment groups were randomized to receive one or three once-daily doses of prulifloxacin 600 mg, with the last administration 3 hours prior to surgery. Central/transitional and peripheral zone prostatic tissue samples were obtained from the 6 o'clock and 9 o'clock positions in the prostate, and blood samples were collected concurrently. Ulifloxacin concentrations were determined in the tissue samples and plasma using liquid chromatography-tandem mass spectrometry. Safety was also assessed. Prostatic tissue concentrations of ulifloxacin always exceeded those in plasma. Mean ulifloxacin concentrations measured in samples collected from the 6 o'clock central/transitional zone of the prostate were higher in patients who received prulifloxacin for 3 days than in those who received a single dose. Mean prostatic tissue/plasma ulifloxacin concentration ratios after single and repeated prulifloxacin administration ranged from 3.8 to 7.1 and from 3.9 to 9.5, respectively. The highest mean ratio was found in the 6 o'clock central/transitional zone after repeated dosing. Prostatic levels of ulifloxacin were above the minimum inhibitory concentrations for the most

    In recent years the amount of digital data in the world has risen immensely. But, the more information exists, the greater is the possibility of its unwanted disclosure. Thus, the data privacy protection has become a pressing problem of the present time. The task of individual privacy-preserving is being thoroughly studied nowadays. At the same time, the problem of statistical disclosure control for collective (or group) data is still open. In this paper we propose an effective and relatively simple (wavelet-based) way to provide group anonymity in collective data. We also provide a real-life example to illustrate the method.

    Full Text Available The empiric antibiotic therapy can result in antibiotic overuse, development of bacterial resistance and increasing costs in critically ill patients. The aim of the present study was to evaluate the effect of procalcitonin (PCT guide treatment on antibiotic use and clinical outcomes of patients admitted to intensive care unit (ICU with systemic inflammatory response syndrome (SIRS.  A total of 60 patients were enrolled in this study and randomly divided into two groups, cases that underwent antibiotic treatment based on serum level of PCT as PCT group (n=30 and patients who undergoing antibiotic empiric therapy as control group (n=30. Our primary endpoint was the use of antibiotic treatment. Additional endpoints were changed in clinical status and early mortality. Antibiotics use was lower in PCT group compared to control group (P=0.03. Current data showed that difference in SOFA score from the first day to the second day after admitting patients in ICU did not significantly differ (P=0.88. Patients in PCT group had a significantly shorter median ICU stay, four days versus six days (P=0.01. However, hospital stay was not statistically significant different between two groups, 20 days versus 22 days (P=0.23.  Early mortality was similar between two groups. PCT guidance administers antibiotics reduce antibiotics exposure and length of ICU stay, and we found no differences in clinical outcomes and early mortality rates between the two studied groups.

    Evolocumab has been shown to consistently reduce low-density lipoprotein cholesterol (LDL-C) across populations. The phase 3 studies included administration in the home-use and in-clinic settings but did not specifically evaluate the feasibility of home-use administration. Two clinical studies enrolled patients with hypercholesterolemia or mixed dyslipidemia on statin therapy and with/without ezetimibe received evolocumab in the home-use setting. Patients were randomized to self-administer evolocumab using one of two injection devices biweekly over 6 weeks (autoinjector or prefilled syringe; n = 149; ClinicalTrials.gov, NCT01849497) or monthly over 12 weeks (autoinjector or automated minidoser; n = 164; NCT01879319). The first self-administration occurred in the in-clinic setting, and two more were performed in the at-home setting. Patients were successful in self-administering evolocumab in the home-use setting in approximately 95 % of attempts and experienced LDL-C reductions from baseline to week 6 or the mean of weeks 10 and 12 of approximately 65 %. Rates of successful self-administration and LDL-C reduction were similar across dosing schedules and study devices. Adverse events were similar between randomized groups and generally mild in severity. In two clinical studies, therefore, patients were able to successfully self-administer evolocumab in both the in-clinic and at-home settings regardless of which dosing schedule or device they used.

    Loxodonta africana are susceptible to a wide variety of parasites that are often treated with the broad spectrum antiparasitic ivermectin (IVM) based on empirical knowledge. The objectives of this study were to 1) measure plasma IVM levels following administration of 0.1 mg/kg IVM p.o., 2) compare plasma IVM levels following administration with regular versus restricted feed rations, 3) measure IVM excretion in feces, and 4) use these findings to generate dosing recommendations for this species. Using a crossover design, six African elephants were divided into two groups. Ivermectin was administered and typical grain rations were either provided or withheld for 2 hr. Blood and fecal samples were collected for 7 days following drug administration. After a 5-wk washout period, groups were switched and the procedure repeated. Plasma and fecal IVM were analyzed using high-performance liquid chromatography. There was no statistically significant difference detected in the pharmacokinetic data between the fed and fasted groups. Peak plasma concentration, area under the curve, and half-life for plasma ranged between 5.41-8.49 ng/ml, 17.1-20.3 ng x day/ml, and 3.12-4.47 day, respectively. High IVM concentrations were detected in feces. The peak concentration values in feces were between 264-311-fold higher than those obtained in plasma. The comparatively large area under the curve and short time to maximum concentration in feces indicate elimination prior to absorption of much of the drug. Plasma IVM concentrations were low when compared to other species. Based on these findings, administration of 0.2-0.4 mg/kg p.o. should be appropriate for eliminating many types of parasites in elephants, and could minimize development of parasite resistance.

    Enteral nutrition is one of the major risk factors for ventilator-associated pneumonia. Abdominal massage is assumed to prevent the development of ventilator-associated pneumonia by reducing residual gastric volume. To identify the effect of abdominal massage administered to critically ill patients with mechanical ventilation and continuous enteral feeding on the development of ventilator-associated pneumonia. A randomized controlled design was used in this study. This study was performed in a critical care unit of a university hospital in Turkey. The sample of the study consisted of a total of 32 patients, selected randomly to receive abdominal massage (n=16) and a control group (n=16). The stratified randomization was used in this study. Patients were stratified according to age and gender. A fifteen-minute abdominal massage was administered to the patients in the intervention group twice daily. No intervention was administered to the patients in the control group. At the end of monitoring days a reduction, compared to the control patients, was identified. The amount of gastric residual volume and abdominal circumference measurement of the patients in the intervention group had decreased. This reduction was found to be significant in the statistical analysis (p0.05). This study revealed that abdominal massage administered to intubated and enterally fed patients reduced gastric residual volume and abdominal distension. In addition, a decrease in the ratio of ventilator-associated pneumonia was determined. Copyright © 2014 Elsevier Ltd. All rights reserved.

    We report observations of the coma of the comet 67P/C-G performed in the near-IR by VIRTIS-M during the escort phase in April 2015. We selected observations performed when the spacecraft was at about 150 km from the nucleus, in order to cover the greatest part of the coma.We have chosen observations: a) with a diffuse coma without any evident strong jets and b) with strong jets originating from the “neck” region of the nucleus.We analyzed the in changes intensity and spectral behavior of the coma along the projected nucleocentric distance, for both the diffuse coma and for the jets.The results show that:- The emission of the grains in the diffuse coma is going as 1/rho in the FoV of VIRTIS, (about 2 km), suggesting the absence of grain fragmentation or sublimation. In the region close to the surface, within about 400 m, there is an increase of the emission, which is probably due to instrumental scattered light from the nucleus that can hide the effects due to the grains acceleration.- Also for the grains in the jets there is no evidence of fragmentation or sublimation in the spectral region where the scattering of the solar radiation is the mechanism of emission. Instead in the thermal region there are strong variations between the regions close to the nucleus and the farther ones.The authors would like to thank ASI (I), CNES (F), DLR (D), NASA (USA) for supporting this research. VIRTIS was built by a consortium formed by Italy, France and Germany, under the scientific responsibility of the “Istituto di Astrofisica e Planetologia Spaziale” of INAF (I), which guides also the scientific operations. The consortium includes also the “Laboratoire d'études spatiales et d'instrumentation en Astrophysique” of the Observatoire de Paris (F), and the “Institut für Planetenforschung” of DLR (D).

    To gain a deeper insight into the potential interactions between individual aromatic hydrocarbons in a mixture, several benzo[a]pyrene (B[a]P) and 7H-dibenzo[c,g]carbazole (DBC) binary mixtures were studied. The biological activity of the binary mixtures was investigated in the HepG2 and WB-F344 liver cell lines and the Chinese hamster V79 cell line that stably expresses the human cytochrome P4501A1 (hCYP1A1). In the V79 cells, binary mixtures, in contrast to individual carcinogens, caused a significant decrease in the levels of micronuclei, DNA adducts and gene mutations, but not in cell survival. Similarly, a lower frequency of micronuclei and levels of DNA adducts were found in rat liver WB-F344 cells treated with a binary mixture, regardless of the exposure time. The observed antagonism between B[a]P and DBC may be due to an inhibition of Cyp1a1 expression because cells exposed to B[a]P:DBC showed a decrease in Cyp1a1 mRNA levels. In human liver HepG2 cells exposed to binary mixtures for 2 h, a reduction in micronuclei frequency was also found. However, after a 24 h treatment, synergism between B[a]P and DBC was determined based on DNA adduct formation. Accordingly, the up-regulation of CYP1A1 expression was detected in HepG2 cells exposed to B[a]P:DBC. Our results show significant differences in the response of human and rat cells to B[a]P:DBC mixtures and stress the need to use multiple experimental systems when evaluating the potential risk of environmental pollutants. Our data also indicate that an increased expression of CYP1A1 results in a synergistic effect of B[a]P and DBC in human cells. As humans are exposed to a plethora of noxious chemicals, our results have important implications for human carcinogenesis. - Highlights: • B[a]P:DBC mixtures were less genotoxic in V79MZh1A1 cells than B[a]P and DBC alone. • An antagonism between B[a]P and DBC was determined in rat liver WB-F344 cells. • The inhibition of CYP1a1 expression by B[a]P:DBC mixture

    Full Text Available Background. Experimental data suggest that oral iron (I. supplementation can worsen colitis in animals. Aim. To investigate the influence of various concentrations of orally administered I. in normal gut mucosa and mucosa of animals with TNBS colitis, as well as the influence of Mesalamine (M. and Prednisolone (P. on the severity of TNBS colitis following orally administered I. Methods and Materials. 156 Wistar rats were allocated into 10 groups. Colitis was induced by TNBS. On the 8th day, all animals were euthanatized. Activity of colitis and extent of tissue damage were assessed histologically. The levels of tissue tumor necrosis factor-α (t-TNF-α and tissue malondialdehyde (t-MDA were estimated in all animal groups. Results. Moderate and high I. supplementation induced inflammation in the healthy colon and increased the activity of the experimentally induced TNBS colitis. Administration of M. on TNBS colitis following moderate iron supplementation (0.3 g/Kg diet resulted in a significant improvement in the overall histological score as well as in two individual histological parameters. M. administration, however, did not significantly reduce the t-TNF-α levels (17.67±4.92 versus 14.58±5.71, P=0.102, although it significantly reduced the t-MDA levels (5.79±1.55 versus 3.67±1.39, P=0.000. Administration of M. on TNBS colitis following high iron supplementation (3.0 g/Kg diet did not improve the overall histological score and the individual histological parameters, neither reduced the levels of t-TNF-α (16.57 ± 5.61 versus 14.65±3.88, P=0.296. However, M. significantly reduced the t-MDA levels (5.99±1.37 versus 4.04±1.41, P=0.000. Administration of P. on TNBS colitis after moderate iron supplementation resulted in a significant improvement in the overall histological score as well as in three individual histological parameters. P. also resulted in a significant reduction in the t-TNF-α levels (17.67±4.92 versus 12.64±3

    A method based on the construction of an image quality discriminant function is proposed. The parameters which characterise it are selected among the typical ones measured in a Tc{sup 99m} - HMPAO cerebral blood flow SPECT. The results are compared among groups of patient's studies who received different activity (430, 640 and 807 MBq), looking for the minimum that guaranty good image quality. A reduction in the administered {sup 99m} Tc-HMPAO activity to the patient down to 430 MBq was possible without affecting the tomographic image quality. The labelling yield was the main parameter that determined the image quality. (author)

    Management of postoperative pain is a common problem in endoscopic sinus surgery. The objective of this study is the evaluation of pregabalin and acetaminophen effects on the management of postoperative pain in patients with nasal polyposis undergoing functional endoscopic sinus surgery (FESS). In this clinical trial, double-blinded study, 70 patients with nasal polyposis who have indication of FESS were enrolled to this study. After operation, patients were divided randomly into pregabalin and acetaminophen therapy groups. The pregabalin group (n = 35) was treated under pregabalin 50 mg TDS and the acetaminophen group (n = 35) was treated under tablet acetaminophen 500 mg/6 h. Each group was administered for 3 d. The visual analogue scale (VAS) was measured in onset, 12, 24, 48 and 72 h after surgery. All data were entered into SPSS software (SPSS Inc., Chicago, IL) and appropriate statistical tests were assessed to every relation. In this study, there was no significant difference between two groups according to VAS in onset (p = .37); however, VAS in 12, 24, 48 and 72 h after operation was significantly lower in the pregabalin group compared with the acetaminophen group (p acetaminophen group (p acetaminophen on the management of postoperative pain in the patients with nasal polyposis undergoing functional endoscopic sinus surgery.

    The current study tested the effectiveness of a self-administered, cognitive-behavioral intervention targeting criminal thinking for inmates in segregated housing: Taking a Chance on Change (TCC). Participants included 273 inmates in segregated housing at state correctional institutions. Reductions in criminal thinking, as assessed by the Psychological Inventory of Criminal Styles-Simplified Version, were found in the general criminal thinking score as well as the proactive and reactive composite scores. Examination of demographic predictors of change (i.e., age, years of education, length of sentence) revealed older and more educated participants decreased in criminal thinking more than younger and less educated participants. For a subset of 48 inmates, completion of TCC was associated with significant reduction of disciplinary infractions. Reductions in reactive criminal thinking predicted reductions in disciplinary infractions. Although further research is needed to determine the effectiveness of TCC in reducing recidivism, the reductions in criminal thinking and disordered conduct suggest this is a promising intervention and mode of treatment delivery. By utilizing self-directed study at an accessible reading level, the intervention is uniquely suited to a correctional setting where staff and monetary resources are limited and security and operational issues limit the feasibility of traditional cognitive-behavioral group treatment.

    As part of an ongoing study of the developmental toxicology of industrial alcohols, this report presents the results of the teratology assessments of 1-butanol, 2-butanol, and t-butanol administered by inhalation to rats. Groups of approximately 15 Sprague-Dawley rats were exposed at 8000, 6000, 3500, or 0 ppm 1-butanol, 7000, 5000, 3500, or 0 ppm 2-butanol, or 5000, 3500, 2000, or 0 ppm t-butanol for 7 hr/day on Gestation Days 1-19 (sperm = 0). In each case, the highest concentration was selected to produce maternal toxicity. Dams were sacrificed on Gestation Day 20, and fetuses were individually weighed, tagged, and examined for external malformations. One-half of the fetuses were stained and examined for skeletal abnormalities, and the other half were examined for visceral defects using the Wilson technique. For each butanol isomer examined, the highest concentration (and the intermediate in some cases) was maternally toxic, as manifest by reduced weight gain and feed intake. Even at a maternally toxic dose, and in spite of a dose-dependent reduction in fetal weights for each isomer, the only teratogenicity observed was a slight increase in skeletal malformations (primarily rudimentary cervical ribs), seen with the highest concentration of 1-butanol. Thus, although teratogenicity was observed at 8000 ppm 1-butanol, and developmental toxicity was observed with each of the butyl alcohol isomers studied, concentrations 50 times the current permissible exposure limits for these three butanol isomers do not produce teratogenicity in rats.

    AIM: To observe the therapeutic effects of liposomeencapsulated adriamycin (LADM) on hepatoma in comparison with adriamycin solution (FADM) and adriamycin plus blank liposome (ADM + BL) administered into the hepatic artery of rats.METHODS: LADM was prepared by pH gradient-driven method. Normal saline, FADM (2 mg/kg), ADM+BL (2 mg/kg), and LADM (2 mg/kg) were injected via the hepatic artery in rats bearing liver W256 carcinosarcoma,which were divided into four groups randomly. The therapeutic effects were evaluated in terms of survival time,tumor enlargement ratio, and tumor necrosis degree.The difference was determined with ANOVA and Dunnett test and log rank test.RESULTS: Compared to FADM or ADM + BL, LADM produced a more significant tumor inhibition (tumor volume ratio: 1.243 ± 0.523 vs 1.883 ± 0.708, 1.847 ± 0.661,P < 0.01), and more extensive tumor necrosis. The increased life span was prolonged significantly in rats receiving LADM compared with FADM or ADM+BL (231.48 v's 74.66, 94.70) (P < 0.05).CONCLUSION: The anticancer efficacies of adriamycin on hepatoma can be strongly improved by liposomal encapsulation through hepatic arterial administration.

    Iron is an essential nutrient needed for multiple biological processes, but it is also an effective pro-oxidant in its reduced form. Environmental sources of iron toxic species include reduced soils from rice plantations, polluted natural areas from metal industry waste, or iron oxides used in soil bioremediation. Few studies have been conducted to assess the toxicity of iron species in insects. The present work aims to assess the oxidative stress effects of ferrous sulfate administered in drinking water after acute exposure (96 h) to adults of the insect model Oncopeltus fasciatus (Dallas). Mortality was higher in exposed groups and significantly associated with iron treatment (OR [95% CI]; 11.8 [6.1-22.7]). Higher levels of body iron content were found in insects exposed to ferrous sulfate, with an increase of 5-6 times with respect to controls. Catalase activity and lipid peroxidation (TBARS content), but not glutathione S-transferase activity, were significantly higher in exposed insects and significantly correlated with body iron content (Pearson coefficient of 0.68 and 0.74, respectively) and between them (0.78). The present work demonstrates that, despite the disruption in water and food intake caused by iron administration, this metal is accumulated by insect causing lipid peroxidation and eliciting an antioxidant response mediated by catalase.

    Full Text Available The efficacy of orally administered powdered aloe juice (Aloe ferox was evaluated against ticks on cattle and against ticks and fleas on dogs. Twelve calves were each infested over a 25-day period with approximately 4000 larvae of Rhipicephalus (Boophilus decoloratus and allocated to 3 groups of 4 calves each. Three days after the last larval infestation and daily for 22 days thereafter, the calves in 1 group were fed 5 mg / kg body weight and those in another 25 mg / kg body weight of powdered aloe juice incorporated in game maintenance pellets, while the animals in the 3rd group received only pellets. Detached female ticks were collected daily and counted and the weights and the fertility of groups of 50 engorged female ticks collected from the animals were ascertained. The powdered aloe juice in the game maintenance pellets had no effect on the tick burdens of the calves or on the fertility of the ticks. Six dogs, in each of 2 groups, were treated daily for 15 consecutive days, commencing on Day -5 before the 1st tick infestation, with either 0.39 g or 0.74 g of powdered aloe juice, administered orally in gelatin capsules, while a 3rd group of 6 dogs served as untreated controls. All the dogs were challenged with Haemaphysalis leachi on Days 0 and +7, and with Ctenocephalides felis on Days+1and +8, and efficacy assessments were made 1 day after flea and 2 days after tick challenge, respectively. Treatment was not effective against ticks or fleas on the dogs.

Forty-four Wistar rats were divided into six experimental groups: (1) non-ligated (NL, n = 6) group, (2) ligature only (LO, n = 6) group, (3) Streptozotocin only (STZ, n = 8) group, (4) STZ and ligature (STZ+LO, n = 8) group, (5) STZ, ligature and systemic administration of 15 mg/kg/day boric acid for 15 days (BA15, n = 8) group and (6) STZ, ligature and systemic administration of 30 mg/kg/day boric acid for 15 days (BA30, n = 8) group. Diabetes mellitus was induced by 60 mg/kg streptozotocin. Silk ligatures were placed at the gingival margin of lower first molars of the mandibular quadrant. The study duration was 15 days after diabetes induction and the animals were sacrificed at the end of this period. Changes in alveolar bone levels were clinically measured and tissues were histopathologically examined. Serum total antioxidant status (TAS), total oxidant status (TOS), calcium (Ca) and magnesium (Mg) levels and oxidative stress index (OSI) were evaluated. Primary outcome was alveolar bone loss. Seconder outcome (osteoblast number) was also measured. At the end of 15 days, the alveolar bone loss was significantly higher in the STZ+LO group compared to the other groups (p boric acid and STZ+LO 30 mg/kg boric acid groups (p > 0.05). Systemically administered boric acid significantly decreased alveolar bone loss compared to the STZ+LO group (p 0.05). The OSI values of the BA30 group were significantly lower than the STZ+LO group (p 0.05). Within the limits of this study, it can be suggested that BA, when administered systemically, may reduce alveolar bone loss in the diabetic rat model.

    Characterizing the variability in transcript levels across breeds and sex in swine for genes that play a role in drug metabolism may shed light on breed and sex differences in drug metabolism. The objective of the study is to determine if there is heterogeneity between swine breeds and sex in transcript levels for genes previously shown to play a role in drug metabolism for animals administered flunixin meglumine or fenbendazole. Crossbred nursery female and castrated male pigs (n = 169) spread across 5 groups were utilized. Sires (n = 15) of the pigs were purebred Duroc, Landrace, Yorkshire or Hampshire boars mated to a common sow population. Animals were randomly placed into the following treatments: no drug (control), flunixin meglumine, or fenbendazole. One hour after the second dosing, animals were sacrificed and liver samples collected. Quantitative Real-Time PCR was used to measure liver gene expression of the following genes: SULT1A1, ABCB1, CYP1A2, CYP2E1, CYP3A22 and CYP3A29. The control animals were used to investigate baseline transcript level differences across breed and sex. Post drug administration transcript differences across breed and sex were investigated by comparing animals administered the drug to the controls. Contrasts to determine fold change were constructed from a model that included fixed and random effects within each drug. Significant (P-value <0.007) basal transcript differences were found across breeds for SULT1A1, CYP3A29 and CYP3A22. Across drugs, significant (P-value <0.0038) transcript differences existed between animals given a drug and controls across breeds and sex for ABCB1, PS and CYP1A2. Significant (P <0.0038) transcript differences across breeds were found for CYP2E1 and SULT1A1 for flunixin meglumine and fenbendazole, respectively. The current analysis found transcript level differences across swine breeds and sex for multiple genes, which provides greater insight into the relationship between flunixin meglumine and

    Objective To estimate the unit costs of administering intravenous (IV) biological agents in day hospitals (DHs) in the Spanish National Health System. Patients and methods Data were obtained from 188 patients with rheumatoid arthritis, collected from nine DHs, receiving one of the following IV therapies: infliximab (n=48), rituximab (n=38), abatacept (n=41), or tocilizumab (n=61). The fieldwork was carried out between March 2013 and March 2014. The following three groups of costs were considered: 1) structural costs, 2) material costs, and 3) staff costs. Staff costs were considered a fixed cost and were estimated according to the DH theoretical level of activity, which includes, as well as personal care of each patient, the DH general activities (complete imputation method, CIM). In addition, an alternative calculation was performed, in which the staff costs were considered a variable cost imputed according to the time spent on direct care (partial imputation method, PIM). All costs were expressed in euros for the reference year 2014. Results The average total cost was €146.12 per infusion (standard deviation [SD] ±87.11; CIM) and €29.70 per infusion (SD ±11.42; PIM). The structure-related costs per infusion varied between €2.23 and €62.35 per patient and DH; the cost of consumables oscillated between €3.48 and €20.34 per patient and DH. In terms of the care process, the average difference between the shortest and the longest time taken by different hospitals to administer an IV biological therapy was 113 minutes. Conclusion The average total cost of infusion was less than that normally used in models of economic evaluation coming from secondary sources. This cost is even less when the staff costs are imputed according to the PIM. A high degree of variability was observed between different DHs in the cost of the consumables, in the structure-related costs, and in those of the care process. PMID:28356746

    Outcome measures can be used in prosthetic practices to evaluate interventions, inform decision making, monitor progress, document outcomes, and justify services. Strategies to enhance prosthetists' ability to use outcome measures are needed to facilitate their adoption in routine practice. To assess prosthetists' use of outcome measures and evaluate the effects of training on their confidence in administering performance-based measures. Cross-sectional and single-group pretest-posttest survey. Seventy-nine certified prosthetists (mean of 16.0 years of clinical experience) were surveyed about their experiences with 20 standardized outcome measures. Prosthetists were formally trained by the investigators to administer the Timed Up and Go and Amputee Mobility Predictor. Prosthetists' confidence in administering the Timed Up and Go and Amputee Mobility Predictor was measured before and after training. The majority of prosthetists (62%) were classified as non-routine outcome measure users. Confidence administering the Timed Up and Go and Amputee Mobility Predictor prior to training was low-to-moderate across the study sample. Training significantly (p confidence in administering both instruments. Prosthetists in this study reported limited use of and confidence with standardized outcome measures. Interactive training resulted in a statistically significant increase of prosthetists' confidence in administering the Timed Up and Go and Amputee Mobility Predictor and may facilitate use of outcome measures in clinical practice. Frequency of outcome measure use in the care of persons with limb loss has not been studied. Study results suggest that prosthetists may not regularly use standardized outcome measures and report limited confidence in administering them. Training enhances confidence and may encourage use of outcome measures in clinical practice. © The International Society for Prosthetics and Orthotics 2014.

  1. The Effect of Compressor-Administered Defibrillation on Peri-shock Pauses in a Simulated Cardiac Arrest Scenario

    Directory of Open Access Journals (Sweden)

    Joshua Glick

    2014-03-01

    Full Text Available Introduction: Coordination of the tasks of performing chest compressions and defibrillation can lead to communication challenges that may prolong time spent off the chest. The purpose of this study was to determine whether defibrillation provided by the provider performing chest compressions led to a decrease in peri-shock pauses as compared to defibrillation administered by a second provider, in a simulated cardiac arrest scenario. Methods: This was a randomized, controlled study measuring pauses in chest compressions for defibrillation in a simulated cardiac arrest model. We approached hospital providers with current CPR certification for participation between July, 2011 and October, 2011. Volunteers were randomized to control (facilitator-administered defibrillation or experimental (compressor-administered defibrillation groups. All participants completed one minute of chest compressions on a mannequin in a shockable rhythm prior to administration of defibrillation. We measured and compared pauses for defibrillation in both groups. Results: Out of 200 total participants, we analyzed data from 197 defibrillations. Compressor-initiated defibrillation resulted in a significantly lower pre-shock hands-off time (0.57 s; 95% CI: 0.47-0.67 compared to facilitator-initiated defibrillation (1.49 s; 95% CI: 1.35-1.64. Furthermore, compressor-initiated defibrillation resulted in a significantly lower peri-shock hands-off time (2.77 s; 95% CI: 2.58-2.95 compared to facilitator-initiated defibrillation (4.25 s; 95% CI: 4.08-4.43. Conclusion: Assigning the responsibility for shock delivery to the provider performing compressions encourages continuous compressions throughout the charging period and decreases total time spent off the chest. However, as this was a simulation-based study, clinical implementation is necessary to further evaluate these potential benefits. [West J Emerg Med. 2014;15(2:246–250.

Iontophoresis is a therapeutic alternative used in the treatment of injury during the inflammatory phase. In recent years, gold nanoparticles (GNP have been studied due to their therapeutic anti-inflammatory capacity and as an alternative to the transport of several proteins. Purpose: This study evaluates the therapeutic effects of iontophoresis using GNPs and diclofenac diethylammonium on inflammatory parameters in rats challenged with traumatic tendinitis.Methods: Wistar rats were divided in three treatment groups (n = 15: (1 iontophoresis + diclofenac diethylammonium; (2 iontophoresis + GNP; and (3 iontophoresis + diclofenac diethylammonium + GNP. External control was formed by challenged tendons without treatment (n = 15. Iontophoresis was administered using 0.3 mA direct current on 1.5 cm² electrodes. Results: The levels of both inflammatory cytokines were significantly higher in untreated challenged rats, when compared with the control (5.398 ± 234 for interleukin 1 beta and 6.411 ± 432 for tumor necrosis factor alpha, which confirms the occurrence of an inflammatory stage in injury (P < 0.05. A significant decrease was observed in expression of cytokines interleukin 1 beta in the three treatment groups, in comparison with untreated challenged tendons, although, in the group treated with diclofenac and GNP, results were similar to the control (1.732 ± 239 (P < 0

    To compare pain control at various time points during first-trimester surgical abortion using a patient-administered lidocaine gel compared with a traditional lidocaine paracervical block. We conducted a randomized controlled trial of women undergoing surgical abortion at less than 12 weeks of gestation in an outpatient setting. The primary outcome was pain at cervical dilation as measured on a 100-mm visual analog scale. A sample size of 142 participants was planned to detect a 15-mm or greater difference on the 100-mm visual analog scale with 90% power and a significance level of .025, adding 10% for participant dropout and protocol violations. Participants received either 12 mL of a 1% lidocaine paracervical block or 20 mL of a self-administered, 2% lidocaine gel 20-30 minutes before procedure initiation. Secondary outcomes included anticipated pain, baseline pain, pain with speculum and tenaculum placement, pain after suction aspiration, and pain 30-45 minutes postoperatively. From April to October 2015, a total of 142 women were enrolled (68 in the paracervical block group, 69 in the gel group, and five not analyzed as a result of participant withdrawal). Sociodemographic characteristics were similar between groups. The mean pain score with cervical dilation was 60 mm (95% confidence interval [CI] 54-66) in the paracervical block group and 64 mm (95% CI 59-69) in the gel group (P=.3). There was no significant difference between mean pain scores at any time points measured. Self-administration of lidocaine gel before first-trimester surgical abortion is noninferior to a traditional paracervical lidocaine block and should be considered as an alternative, noninvasive approach to pain control for first-trimester surgical abortion.

    To evaluate the efficacy of a self-administered cognitive training program for improving cognition in normal elderly persons. A multisite, randomized control, double-blind trial was conducted with 28 experimental participants (Mage = 70.7 ± 8.89) and 28 active controls (Mage = 74.4 ± 9.39). Treatment conditions: experimental intervention (EI) consisted of three modules: (1) executive functioning, (2) memory, and (3) emotion training. Active control (AC) consisted of word searches, reading short stories, and answering multiple-choice questions. Treatments were self-administered one hour/five days a week for four weeks. Pre-and post-training neuropsychological outcome measures were utilized as determinants of program success. Compared to the AC group, the EI group displayed significant gains on targeted executive (p = .002) and memory (p cognition (BCRS, p = .002) and functional abilities (DAD, p memory (55% vs. 19.5%) and functional (41% vs. 7.5%) ability. Participant recruitment and compliance rates were enhanced by the involvement of a physician. Results support the efficacy of self-directed cognitive training in reliably improving cognitive and functional abilities in normal older adults. While physicians are critical in enhancing the delivery of regimented treatment, the present study illustrates the potential for self-directed prophylactic training in deterring the development of cognitive decline.

    Full Text Available Background. Osteoarthritis (OA is more prevalent in women, particularly after menopausal age. Women are more likely to seek complementary and alternative medicine (CAM approaches. We examined the feasibility of training self-administered acupressure exercise and assessed its impact on OA symptoms among women with knee OA. Methods. Thirty-six eligible postmenopausal women were randomly assigned in the acupressure exercise group (n=15 or the control group (n=21 for 12 weeks. Feasibility outcomes (e.g., compliance and adverse effects and clinical outcomes (e.g., pain, stiffness, and physical function were assessed. Data were collected at baseline, 6 weeks and 12 weeks. Both per-protocol and intention-to-treat analysis were employed. Results. The training materials were well received. The feedback from participants suggests that self-administered acupressure exercise is easy to learn and safe to perform at home, although no statistically significant results of the clinical outcome were observed. Our findings didn’t reveal superiority or inferiority of acupressure compared with usual care. Conclusion. Acupressure exercise is feasible to be trained among postmenopausal women with knee osteoarthritis. Due to the limitations of this study such as small sample size and high attrition rate, acupressure’s efficacy needs to be further explored in larger scale studies with more rigorous design.

    2003-02-01

    Self-administered treatments are a cost-effective way to treat a broad spectrum of people. This article focuses on the existing research of self-administered treatments and their effectiveness when integrated with ongoing practice or when implemented alone. Evidence for their effectiveness is mixed; self-help has been proven successful in the treatment of depression, mild alcohol abuse, and anxiety disorders. It has proven less successful for smoking cessation and moderate to severe alcohol abuse. When determining whether self-administered treatment is appropriate, individual characteristics and attitude as well as the nature and severity of the problem should be taken into consideration. In addition, because many self-help treatments have not been evaluated, caution should be exercised when implementing self-administered treatment, and progress should be carefully monitored.

    An automated model development was performed for simvastatin, co-administered with amlodipine concurrently or non-concurrently (i.e., 4 hours later) in 17 patients with coexisting hyperlipidemia and hypertension. The single objective hybrid genetic algorithm (SOHGA) was implemented in the NONMEM software by defining the search space for structural, statistical and covariate models. Candidate models obtained from the SOHGA runs were further assessed for biological plausibility and the precision of parameter estimates, followed by traditional backward elimination process for model refinement. The final population pharmacokinetic model shows that the elimination rate constant for simvastatin acid, the active form by hydrolysis of its lactone prodrug (i.e., simvastatin), is only 44% in the concurrent amlodipine administration group compared with the non-concurrent group. The application of SOHGA for automated model selection, combined with traditional model selection strategies, appears to save time for model development, which also can generate new hypotheses that are biologically more plausible.

    Recently, nasal administration has been studied as a noninvasive route for delivery of plasmid DNA encoding therapeutic or antigenic genes. Here, we examined the brain targeting efficiency and transport pathways of intranasally administered plasmid DNA. Quantitative polymerase chain reaction (PCR) measurements of plasmid DNA in blood and brain tissues revealed that intranasally administered pCMVbeta (7.2 kb) and pN2/CMVbeta (14.1 kb) showed systemic absorption and brain distribution. Following intranasal administration, the beta-galactosidase protein encoded by these plasmids was significantly expressed in brain tissues. Kinetic studies showed that intranasally administered plasmid DNA reached the brain with a 2,595-fold higher efficiency than intravenously administered plasmid DNA did, 10 min post-dose. Over 1 h post-dose, the brain targeting efficiencies were consistently higher for intranasally administered plasmid DNA than for intravenously administered DNA. To examine how plasmid DNA enters the brain and moves to the various regions, we examined tissues from nine brain regions, at 5 and 10 min after intranasal or intravenous administration of plasmid DNA. Intravenously administered plasmid DNA displayed similar levels of plasmid DNA in the nine different regions, whereas, intranasally administered plasmid DNA exhibited different levels of distribution among the regions, with the highest plasmid DNA levels in the olfactory bulb. Moreover, plasmid DNA was mainly detected in the endothelial cells, but not in glial cells. Our results suggest that intranasally applied plasmid DNA may reach the brain through a direct route, possibly via the olfactory bulb, and that the nasal route might be an alternative method for efficiently delivering plasmid DNA to the brain.

    Objective To investigate the relationship between interleukin -6 (IL- 6) gene -572C/G polymorphism and systemic inflammatory response syndrome (SIRS) in children. Methods The research design was a case -control study. A total of 53 children admitted to our hospital with SIRS served as SIRS group while 50 healthy children as healthy control group( All children were Han nationality of Shenzhen city, Guangdong province). DNA was extracted from peripheral vein blood by phenol / chloroform method and serum was also prepared.Primer DNA was designed to amplify PCR product covering the part of IL -6 gene promoter carrying the analyzed transversion. Then ,this PCR product was cut with restriction enzyme by polymerase chain reaction - restriction fragment length polymorphism method. Cleavage product was detected by agarose gel electrophoresis. Genotype frequencies and allele frequencies of the children in 2 groups were analyzed. The serum level of IL - 6 was measured by enzyme - linked immunosorbent assay. The data was analyzed by SPSS 13.0 software. Results The frequencies of the genotype GG and G allele of the IL -6 (-572) site in the SIRS group were significantly higher than those in healthy control group(Pa <0.05). The risk of SIRS of the G allele carriers was 5.91 times that of the C allele carriers(95% CI: 2.76 - 12.64). The serum level of IL - 6 in SIRS group was significantly higher than that in healthy control group( P < 0.05 ) ,the serum level of IL - 6 with the G allele carriers was significantly higher than that with the CC gene carriers( P < 0.05 ). Conclusions IL -6 gene -572C/G polymorphism is significantly correlated with the SIRS in Chinese Hah children. Serum IL - 6 level maybe affected by the gene polymorphism.%目的 探讨IL-6基因-572C/G多态性与小儿全身炎症反应综合征(SIRS)的关系.方法 选用病例-对照的研究方法,以本院53例SIRS患儿为SIRS组,并随机挑选50例健康儿童为健康对照组(所有儿童均为汉

    Objective To explore the prevention of IL-18 or anti-IL-18-mAb to the immune liver fibrosis model induced by repeated injection of concanavalin A in BALB/c mice and its mechanism. Methods Total of 120 BALB/c mice were divided into four groups, control group mice (Ga) were injected weekly with normal saline, concanavalin A group was divided into Gb, Gc, Gd. All mice were injected with concanavalin A (15 mg/kg) once a week. Moreover, Gc, Gd mice were injected weekly with IL-18 (7.5 mg/kg) and anti-IL-18-mAb (10 mg/kg) 2 hours before treatment with concanavalin A, respectively. Twenty-four hours after concanavalin A challenge at 1, 5, 12 and 20 weeks, 3 mice were killed by vena orbitalis, repectively. The sera were storaged at 4℃for detecting of up TNF-αand IFN-γby ELISA. The liver of mice in different groups were excised and fixed in 10%formalin for HE staining and Masson staining or frozen in liquid nitrogen for immunohistochemical staining forα-SMA. After extracting of total RNA from liver tissue, MMP-2 and TIMP-1 A messenger RNA were amplified by reverse transcription polymerase chain reaction (PCR). Products were electrophoresed on agrose gel containing ethidium bromide and visualized under ultraviolet light. Densitometric RT-PCR data were standardized withβ-actin signals. Results After experiment, the number of dead mice of Ga, Gb, Gc and Gd were 0, 6, 15 and 3, respectively. There were significant difference on each group (P<0.05). At the fifth week of experiment, hepatocellular necrosis in IL-18 administered group mice had become widespread throughout the lobule. Evidence of liver fibrosis was observed during this period. However, at the twelfth week of experimemt, bridging fibrosis and large fibrosis strip in the parenchyma with hepatocellular necrosis was detectable in Gb, but at twentieth week, only the small fibrosis strip had been found in anti-IL-18-mAb administered group mice by HE staining and Masson staining.

  19. Reduction of Pavlovian Bias in Schizophrenia: Enhanced Effects in Clozapine-Administered Patients.

    Directory of Open Access Journals (Sweden)

    Matthew A Albrecht

    Full Text Available The negative symptoms of schizophrenia (SZ are associated with a pattern of reinforcement learning (RL deficits likely related to degraded representations of reward values. However, the RL tasks used to date have required active responses to both reward and punishing stimuli. Pavlovian biases have been shown to affect performance on these tasks through invigoration of action to reward and inhibition of action to punishment, and may be partially responsible for the effects found in patients. Forty-five patients with schizophrenia and 30 demographically-matched controls completed a four-stimulus reinforcement learning task that crossed action ("Go" or "NoGo" and the valence of the optimal outcome (reward or punishment-avoidance, such that all combinations of action and outcome valence were tested. Behaviour was modelled using a six-parameter RL model and EEG was simultaneously recorded. Patients demonstrated a reduction in Pavlovian performance bias that was evident in a reduced Go bias across the full group. In a subset of patients administered clozapine, the reduction in Pavlovian bias was enhanced. The reduction in Pavlovian bias in SZ patients was accompanied by feedback processing differences at the time of the P3a component. The reduced Pavlovian bias in patients is suggested to be due to reduced fidelity in the communication between striatal regions and frontal cortex. It may also partially account for previous findings of poorer "Go-learning" in schizophrenia where "Go" responses or Pavlovian consistent responses are required for optimal performance. An attenuated P3a component dynamic in patients is consistent with a view that deficits in operant learning are due to impairments in adaptively using feedback to update representations of stimulus value.

    The effectiveness of orally administered tylosin tartrate for the control of naturally occurring pneumonia was determined in 287 neonatal calves. Tylosin tartrate was mixed with reconstituted milk replacer at the time of feeding. Daily doses of 1.0 g (0.5 g BID), 2.0 g (1.0 g BID) and 4.0 g (2.0 g BID) were evaluated for periods ranging from seven to 28 days. Tylosin at the optimum dose of 2.0 g daily reduced mortality to 12 out of 95 (12.6 per cent) compared to 38 out of 89 (42.7 per cent) in the non-medicated control calves. The 1.0 g daily dose did not reduce mortality. The number of calves with moderate to severe lung lesions was also reduced by treatment at 2.0 g daily to 13 out of 95 (13.7 per cent) compared to 45 out of 89 (50.6 per cent) in the control group. All dose levels had a similar effect in reducing the severity of clinical signs indicative of respiratory disease. Tylosin treatment at all dose levels reduced the number of Pasteurella multocida isolations from lung tissue to 15/146 (10.3 per cent) compared to 61/141 (43.3 per cent) for the controls. However, there were no differences between treated and controls in the number of P haemolytica isolations. The frequency of mycoplasma isolations from lung tissue were reduced significantly by tylosin treatment at the 4.0 g and 2.0 g dose levels to 36/93 (38.7 per cent) compared to 61/86 (70.9 per cent) for the control calves.

    BACKGROUND:Musicians are frequently affected by playing-related musculoskeletal disorders (PRMD). Common solutions used by Western medicine to treat musculoskeletal pain include rehabilitation programs and drugs, but their results are sometimes disappointing. OBJECTIVE:To study the effects of self-administered exercises based on Tuina techniques on the pain intensity caused by PRMD of professional orchestra musicians, using numeric visual scale (NVS). DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: We performed a prospective, controled, single-blinded, randomized study with musicians suffering from PRMD. Participating musicians were randomly distributed into the experimental (n= 39) and the control (n= 30) groups. After an individual diagnostic assessment, speciifc Tuina self-administered exercises were developed and taught to the participants. Musicians were instructed to repeat the exercises every day for 3 weeks. MAIN OUTCOME MEASURES: Pain intensity was measured by NVS before the intervention and after 1, 3, 5, 10, 15 and 20 d of treatment. The procedure was the same for the control group, however the Tuina exercises were executed in points away from the commonly-used acupuncture points. RESULTS: In the treatment group, but not the control group, pain intensity was signiifcantly reduced on days 1, 3, 5, 10, 15 and 20. CONCLUSION: The results obtained are consistent with the hypothesis that self-administered exercises based on Tuina techniques could help professional musicians controling the pain caused by PRMD. Although our results are very promising, further studies are needed employing a larger sample size and double blinding designs.

  5. Systemically administered IgG anti-toxin antibodies protect the colonic mucosa during infection with Clostridium difficile in the piglet model.

    Directory of Open Access Journals (Sweden)

    Ocean R Cohen

    Full Text Available The use of anti-toxin human monoclonal antibodies (HMab as treatment for C. difficile infection has been investigated in animal models and human clinical trials as an alternative to or in combination with traditional antibiotic therapy. While HMab therapy appears to be a promising option, how systemically administered IgG antibodies protect the colonic mucosa during Clostridium difficile infection is unknown. Using the gnotobiotic piglet model of Clostridium difficile infection, we administered a mixture of anti-TcdA and anti-TcdB HMabs systemically to piglets infected with either pathogenic or non-pathogenic C. difficile strains. The HMabs were present throughout the small and large intestinal tissue of both groups, but significant HMabs were present in the lumen of the large intestines only in the pathogenic strain-infected group. Similarly, HMabs measured in the large intestine over a period of 2-4 days following antibody administration were not significantly different over time in the gut mucosa among the groups, but concentrations in the lumen of the large intestine were again consistently higher in the pathogenic strain-infected group. These results indicate that systemically administered HMab IgG reaches the gut mucosa during the course of CDI, protecting the host against systemic intoxication, and that leakage through the damaged colon likely protects the mucosa from further damage, allowing initiation of repair and recovery.

    To determine whether changes in the format of teaching pathology and the introduction of active learning principles can improve medical students' performance on external examinations and enhance clinical skills. The sophomore Pathology Course at Jefferson Medical College (JMC) in Philadelphia, Pennsylvania, USA, was completely restructured in 1986, with greater emphasis placed on independent study, small group teaching, and case study discussion. We used the scores of JMC medical students on the National Board of Medical Examiners (NBME) Part I Examination to compare the performance of JMC students who completed their medical education before curricular change (entering classes 1982-1984) with the performance of subsequent generations of students who were taught according to the reformed curriculum (entering classes 1985-1988). The two groups of students were comparable in terms of standard social and psychometric parameters, such as mean age at matriculation, female/male ratio, ratio of minority students in the class, premedical college grade point averages, and mean scores on the preadmission Medical College Admissions Test. JMC students who studied pathology prior to the curricular reform received on the pathology subsection of the NBME Part I Examination reform scores that were close to the national average. In contrast, mean scores for students who studied pathology after curricular changes were significantly higher than the national average (P<0.001). Based on their pathology subscores, the number of JMC students scoring below the cutoff line for passing (380 points) decreased significantly after the curricular reform, whereas the number of high-scoring students whose scores ranked them in the 90th percentile nationally increased. Curricular reform was also associated with an increase in overall student satisfaction. Curricular changes that include an emphasis on active learning can improve the performance of medical students on externally administered

    Japanese encephalitis (JE) virus is a major cause of disease, disability, and death in Asia. An effective, live, attenuated JE vaccine (LJEV) is available; however, its use in routine immunization schedules is hampered by lack of data on concomitant administration with measles vaccine (MV). This study evaluated the immunogenicity and reactogenicity of LJEV and MV when administered at the same or separate study visits in infants younger than 1 year of age. Three groups of healthy infants were randomized to receive LJEV at age of 8 months and MV at 9 months (Group 1; n=100); MV and LJEV together at 9 months (Group 2; n=236); or MV and LJEV at 9 and 10 months, respectively (Group 3; n=235). Blood was obtained 4 weeks after each vaccine administration to determine antibody levels for measles and JE. Reactogenicity was assessed by parental diaries and clinic visits. Four weeks after immunization, measles seroprotection rates (defined as > or =340 mIU/ml) were high and comparable in all three groups and specifically, rates in the combined MV-LJEV (Group 2) were not statistically inferior to those in Group 3 receiving MV separately (96% versus 100%, respectively). Likewise, the LJEV seroprotection rates were high and similar between the three groups. The reactogenicity profiles of the three vaccine schedules were also analogous. LJEV and MV administered together are well tolerated and immunogenic in infants younger than 1 year. These results should facilitate incorporation of LJEV into routine immunization schedules with MV.

    Severe H2S poisoning leads to death by rapid respiratory and cardiac arrest, the latter can occur within seconds or minutes in severe forms of intoxication. To determine the time course and the nature of H2S-induced cardiac arrest and the effects of high-dose hydroxocobalamin administered after the end of sulfide exposure. NaHS was infused in 16 sedated mechanically ventilated sheep to reach concentrations of H2S in the blood, which was previously found to lead to cardiac arrest within minutes following the cessation of H2S exposure. High-dose hydroxocobalamin (5 g) or saline solution was administered intravenously, 1 min after the cessation of NaHS infusion. All animals were still alive at the cessation of H2S exposure. Three animals (18%) presented a cardiac arrest within 90 s and were unable to receive any antidote or vehicle. In the animals that survived long enough to receive either hydroxocobalamin or saline, 71% (5/7) died in the control group by cardiac arrest within 10 min. In all instances, cardiac arrest was the result of a pulseless electrical activity (PEA). In the group that received the antidote, intravenous injection of 5 g of hydroxocobalamin provoked an abrupt increase in blood pressure and blood flow; PEA was prevented in all instances. However, we could not find any evidence for a recovery in oxidative metabolism in the group receiving hydroxocobalamin, as blood lactate remained elevated and even continued to rise after 1 h, despite restored hemodynamics. This, along with an unaltered recovery of H2S kinetics, suggests that hydroxocobalamin did not act through a mechanism of H2S trapping. In this sheep model, there was a high risk for cardiac arrest, by PEA, persisting up to 10 min after H2S exposure. Very high dose of hydroxocobalamin (5 g), injected very early after the cessation of H2S exposure, improved cardiac contractility and prevented PEA.

    Recent studies on the intraperitoneal administration of radiolabeled monoclonal antibodies indicate that the diaphragm and, in particular, the lymphatics associated with the diaphragm are more involved in the transport of such high-molecular-mass moieties than was earlier suspected. The current study examines the role of the diaphragm in the i.p. transport of an IgG2a murine monoclonal antibody, 5G6.4, by observing the effect on the absorption of the antibody produced when the diaphragm has been scarred. Normal, sham-operated, and diaphragmatically scarred (abrasions made with 600-grade sandpaper) female Sprague Dawley rats (150-250 g) were administered intraperitoneal injections of 125labeled 5G6.4 in a volume of 2.0 cm3. Approximately 5 micrograms antibody protein was administered in the individual 19-microCi injections per rat. Scarring was effective in partially blocking the amount of labeled antibody that crossed the diaphragm. Mean diaphragm levels (% injected dose/g) of 125I-labeled 5G6.4 from the scarred group were 16.8% lower than values from the sham-operated rats and 37.2% lower than those from the control rats. The blockade was effective in slowing the appearance of the labeled antibody in the systemic circulation. The half-time to absorption was significantly prolonged in the scarred group; mean t1/2 absorption values of 2.5 h for the control group, 5.3 h for the sham-operated group, and 9.6 h for the diaphragmatically blocked group were recorded. Scarring the diaphragm reduced the mean maximum blood concentration by 27.6% over the control group and 23.9% over the sham-operated group. The mean time to maximum blood concentration was lengthened by 93..0% over the control group and 35.3% over the sham-operated group due as a result of scarification. Presumably this impedence to absorption would increase the time that the radiolabeled antibody bathed the peritoneal space. The scarred group also had the largest "system mean residence time" (162.5 h

    The aim of study was to quantitatively evaluate the effects of self-administered facial massage, which was done by hand or facial roller. In this study, the psychophysiological effects of facial massage were evaluated. The central nerves system and the autonomic nervous system were administered to evaluate physiological system. The central nerves system was assessed by Electroencephalogram (EEG). The autonomic nervous system were assessed by peripheral skin temperature(PST) and heart rate variability (HRV) with spectral analysis. In the spectral analysis of HRV, the high-frequency components (HF) were evaluated. State-Trait Anxiety Inventory (STAI), Profile of Mood Status (POMS) and subjective sensory amount with Visual Analog Scale (VAS) were administered to evaluate psychological status. These results suggest that kept brain activity and had strong effects on stress alleviation.

    The aim of this study was to examine the efficacy of epidurally administered mepivacaine on recovery from vecuronium-induced neuromuscular block. Eighty patients were randomly assigned to one of two study groups. They were either given epidurally a bolus of 0.15 ml kg(-1) of mepivacaine 2%, followed by repetitive injections of 0.1 ml kg(-1) h(-1) throughout the study, or were not given epidurally. General anaesthesia was induced and maintained with fentanyl, propofol and nitrous oxide. Neuromuscular block was induced with vecuronium 0.1 mg kg(-1) and monitored using acceleromyographic train-of-four (TOF) at the adductor pollicis. Patients in each treatment group were randomized to receive neostigmine 0.04 mg kg(-1) at 25% recovery of the first twitch of TOF or to recover spontaneously to a TOF ratio of 0.9. The effect of epidural mepivacaine on speed of spontaneous and facilitated recovery of neuromuscular function was evaluated. The time from administration of vecuronium to spontaneous recovery to a TOF ratio of 0.9 was significantly longer in the epidural mepivacaine group [105.4 (14.2) min] as compared with the control group [78.5 (9.1) min, P mepivacaine delays considerably the TOF recovery from neuromuscular block.

    Stepped behavioral health care models have begun to receive increased attention. Self-administered treatments deserve consideration as an element in these models for some disorders and for some consumers. Features suggesting inclusion include low cost, wide availability, and evidence-based status. We present a stepped-care model for depression inclusive of a self-administered treatment component. We also discuss cautions such as depression severity and consumer preference. Evaluation of the efficacy and cost effectiveness of this approach to depression treatment is necessary.

(Rosaceae) was administered daily at dosage rates of 10, 100 and 1,000 mg/kg body mass to randomized groups of Sprague Dawley rats. The extract caused a moderate rise in plasma alanine aminotransferase and creatine kinase mainly at rates of 1,000 mg/kg body mass, but it did not cause any significant variations in haematological parameters or in plasma levels of total proteins, albumin, aspartate aminotransferase, alkaline phosphatase and blood urea nitrogen at the dosage levels used. There were no overt clinical signs in any of the rats. It was concluded that the extract may contain components that are mildly toxic to the liver and heart of rats after repeated daily oral administrations of 1,000 mg/kg body mass.

    Background The apparent interactions between the mechanisms of action of non-steroidal anti-inflammatory drugs (NSAIDS) and steroids suggest that co-therapy may provide beneficial inflammatory and pain relief in the absence of side effects. The aim of the study was to compare the effect of co-administered dexamethasone and diclofenac potassium (diclofenac K) with diclofenac K alone on the postoperative pain, swelling and trismus after surgical removal of third molars. Patients and Methods A prospective randomized double-blind study was conducted at the Department of Oral and Maxillofacial Surgery, Lagos University Teaching Hospital, Nigeria. A total of 100 patients were randomly allocated to two treatment groups of dexamethasone (prophylactic 8 mg and postoperative 4 mg IV) and diclofenac K (50 mg Oral before and after surgery), and diclofenac K alone (as with first group). The overall analgesic efficacy of the drug combinations was assessed postoperatively by determination of pain intensity using a category rating scale. Facial swelling was measured using a tape measure placed from tragus to gonion to tragus, while interincisal mouth-opening of patients was measured using a vernier calibrated caliper pre-operatively and post-operatively. Results Co-administration of dexamethasone and diclofenac K was significantly superior to diclofenac alone for the relief of pain (P trismus relief between the two medication protocols (P > 0.05). Conclusion This study illustrates enhanced effects of co-administered dexamethasone and diclofenac K on short-term post-operative pain and swelling, compared to diclofenac potassium alone in third molar surgery.

    To investigate the validity of the 100 kVp setting in CT venography (CTV) in the diagnosis of deep vein thrombosis (DVT), and to evaluate the feasibility of reducing the amount of administered iodine in this setting. After receiving the contrast medium (CM) of 2.0 mL/kg, 88 patients underwent CTV of the pelvis and lower extremities by using one of four protocols: Group A, 120 kVp setting and 370 mgI/mL CM; group B, 120 kVp and 300 mgI/mL; group C, 100 kVp and 370 mgI/mL; group D, 100 kVp and 300 mgI/mL. The groups were evaluated for venous attenuation, vein-to-muscle contrast-to-noise ratio (CNR{sub VEIN}), DVT-to-vein contrast-to-noise ratio (CNR{sub DVT}), and subjective degree of venous enhancement and image quality. Venous attenuation and CNR{sub VEIN} were significantly higher in group C (144.3 Hounsfield unit [HU] and 11.9), but there was no significant difference between group A (118.0 HU and 8.2) and D (122.4 HU and 7.9). The attenuation value of DVT was not significantly different among the four groups, and group C had a higher absolute CNR{sub DVT} than the other groups. The overall diagnostic image quality and venous enhancement were significantly higher in group C, but there was no difference between groups A and D. The 100 kVp setting in CTV substantially help improve venous enhancement and CNR{sub VEIN}. Furthermore, it enables to reduce the amount of administered iodine while maintaining venous attenuation, as compared with the 120 kVp setting.

    Gemifloxacin mesylate (SB-265805-S, LB-20304a) is a potent, novel fluoroquinolone agent with a broad spectrum of antibacterial activity. The pharmacokinetics and tolerability of oral gemifloxacin were characterized in two parallel group studies in healthy male volunteers after doses of 160, 320, 480, and 640 mg once daily for 7 days. Multiple serum or plasma and urine samples were collected on days 1 and 7 and were analyzed for gemifloxacin by high-performance liquid chromatography (HPLC)-fluorescence (study 1) or HPLC-mass spectrometry (study 2). Safety assessments included vital signs, 12-lead electrocardiogram (ECG) readings, hematology, clinical chemistry, urinalysis, and adverse experience monitoring. Gemifloxacin was rapidly absorbed, with a time to maximum concentration of approximately 1 h after dosing followed by a biexponential decline in concentration. Generally, maximum concentration and area under the concentration-time curve (AUC) increased linearly with dose after either single or repeat doses. Mean +/- standard deviation values of AUC(0-tau) on day 7 were 4.92 +/- 1.08, 9.06 +/- 2.20, 12.2 +/- 3.69, and 20.1 +/- 3.67 microg x h/ml following 160-, 320-, 480-, and 640-mg doses, respectively. The terminal-phase half-life was approximately 7 to 8 h, independent of dose, and was similar following single and repeated administrations. There was minimal accumulation of gemifloxacin after multiple dosing. Approximately 20 to 30% of the administered dose was excreted unchanged in the urine. The renal clearance was 160 ml/min on average after single and multiple doses, which was slightly greater than the accepted glomerular filtration rate (approximately 120 ml/min). These data show that the pharmacokinetics of gemifloxacin are linear and independent of dose. Gemifloxacin was generally well tolerated, although one subject was withdrawn from the study after 6 days at 640 mg for mild, transient elevations of alanine aminotransferase and aspartate

    Food allergy is a common cause of anaphylaxis, and early treatment with epinephrine can be life-saving. We sought to determine the ability of families with food allergic children and pediatricians to properly use self-injectable epinephrine. We enrolled families of consecutive, food-allergic pediatric patients newly referred to our allergy practice but previously prescribed epinephrine and a sampling of pediatricians. Parents or teenage patients answered a structured questionnaire concerning use of self-injectable epinephrine and demonstrated the use of devices with which they were familiar. Demonstrations were scored in a standard manner. One hundred one families of food-allergic children (mean age of patients, 6.4 years) were enrolled. Self-injectable epinephrine was prescribed (mean of 2.7 years previously) primarily by pediatricians (n = 46) and allergists (n = 49). Patients were prescribed EpiPen (n = 93), EpiE-Z Pen (n = 11), and Ana-Kit (n = 3). Eighty-six percent of the families responded that they had the device with them "at all times," but only 71% of this group had epinephrine at the visit. Among those with the epinephrine, 10% had devices beyond the labeled expiration date. Thus, only 55% of the 101 families had unexpired epinephrine on-hand at the time of the survey. Among children in school, 77% had the medication available in school, and 81% stated that the school knew the indications for administration. Only 32% of the participants correctly demonstrated the use of the device. Twenty-nine attending pediatricians were enrolled (mean 14 yrs in practice; mean 4 epinephrine prescriptions/year). Familiarity with the devices was as follows: EpiPen (86%), EpiE-Z Pen (17%) and Ana-Kit (7%). Only 24% generally gave patients written materials concerning indications. Overall, 18% were familiar with and able to demonstrate correct use of at least 1 device (21% correctly demonstrated Epi-Pen). Seventeen pediatric residents were enrolled; 65% were familiar with

    Mobile devices are increasingly used to administer self-report measures of mental health symptoms. There are significant differences, however, in the way that information is presented on mobile devices compared to the traditional paper forms that were used to administer such measures. Such differences may systematically alter responses. The present study evaluated if and how responses differed for a self-report measure, the PTSD Checklist (PCL), administered via mobile device relative to paper and pencil. Participants were 153 trauma-exposed individuals who completed counterbalanced administrations of the PCL on a mobile device and on paper. PCL total scores (d = 0.07) and item responses did not meaningfully or significantly differ across administrations. Power was sufficient to detect a difference in total score between administrations determined by prior work of 3.46 with a d = 0.23. The magnitude of differences between administration formats was unrelated to prior use of mobile devices or participant age. These findings suggest that responses to self-report measures administered via mobile device are equivalent to those obtained via paper and they can be used with experienced as well as naïve users of mobile devices.

    2016-01-01

    The COOP/WONCA test was initially proposed as a self-report in which the answers were supported by drawings illustrating the state investigated. Subsequent studies have confirmed its usefulness as a mere verbal self-report face-to-face administered. No data have been found about its useful when administered by telephone interview. The aim of this study was to determine the psychometric properties of the COOP / WONCA test to measure Related Quality of Life (HRQoL) administered by telephone and compare them with those obtained in other forms of prior administration. Cross-sectional study on a random. City of Madrid. Random sample of 802 adult subjects, representative of the adult population in Madrid, obtained by stratification from the population census. Questionnaire COOP/WONCA with 9 ítems included in a broader battery, administered by telephone interview. The unrestricted factor analysis points to the unifactoriality of the scale, which measures a single latent construct (HRQOL), showing high internal consistency, not significantly different from those found by face-to-face administration, ruling out the existence of biases in the phone modality. The COOP/WONCA test appears as a reliable and valid measure of HRQOL and telephonic administration allows to assume no changes in the results, which can reduce costs in population studies, increasing efficiency without loss of quality in the information collected.

    Gaikowski, Mark P.; Wolf, Jeffery C.; Endris, Richard G.; Gingerich, William H.

    2003-01-01

    Aquaflor, a feed premix containing the broad spectrum antibacterial agent florfenicol (50% w/w), is being developed for use to control enteric septicemia (ESC) in channel catfish Ictalurus punctatus caused by the gram-negative enterobacterium Edwardsiella ictaluri. The recommended dose of Aquaflor to control ESC is 10 mg/kg body weight (BW)/day for 10 days. The study objective was to determine the safety of Aquaflor administered in feed to channel catfish at doses of 0 (control), 10, 30, and 50 mg/kg BW/day for 20 consecutive days. Parameters evaluated included daily mortality, behavioral (appetite, distribution, flight/fright response), and water chemistry observations, initial and terminal weight measurements, and gross and microscopic pathology. Medicated feed consumption was 67-86% of target with group mean doses of 8.5 mg/kg BW/day, 24.6 mg/kg BW/day, and 34.9 mg/kg BW/day. There were no mortalities or clinically observable changes noted at any of the dose levels tested. Aquaflor-related changes were limited to the food consumption and histopathology data. Although Aquaflor-related decreased feed consumption was noted in the 30 and 50 mg/kg BW/day groups, there were no differences in fish growth among the treatment groups. Aquaflor-related histopathology findings were limited to a histomorphologically evident dose-dependent decrease in hematopoietic/lymphopoietic tissue in the anterior kidneys, posterior kidneys, and spleens of channel catfish.

    Background: Although bone grafts are commonly used in reconstructive surgeries, they are sensitive to local perfusion and are thus prone to severe resorption. Biphosphonates can inactivate osteoclasts and can be used to control the undesirable bone resorption. Objective: To assess the effect of administration of biphosphonates on bone resorption. Methods: 20 patients with bony defects who were candidates for free autogenous grafts were randomized into “pamidronate” and “control” groups. Bone segments were soaked in either pamidronate solution or normal saline and were inserted into the area of the surgery. Bone densities were measured post-surgery and in 6-month follow-up. Data were obtained via Digora software and analyzed. Results: The mean±SD bone density in pamidronate group changed from 93.4±14.6 to 93.6±17.5 (p<0.05); in the control group the density decreased from 89.7±13.2 to 78.9±11.4 (p<0.05). The mean difference of bone density in anterior areas of the jaws showed higher DXA in comparison to posterior regions (p=0.002). Conclusion: Locally administered pamidronate affects reduction in bone resorption.

    Full Text Available Abstract Background Medical and public health importance of pneumococcal infections justifies the implementation of measures capable of reducing their incidence and severity, and explains why the recently marketed heptavalent pneumococcal conjugate vaccine (PCV-7 has been widely studied by pediatricians. This study was designed to evaluate the impact of PCV-7 administered at 3, 5 and 11 months of age on respiratory tract infections in very young children. Methods A total of 1,571 healthy infants (910 males aged 75–105 days (median 82 days were enrolled in this prospective cohort trial to receive a hexavalent vaccine (DTaP/IPV/HBV/Hib and PCV-7 (n = 819 or the hexavalent vaccine alone (n = 752 at 3, 5 and 11 months of age. Morbidity was recorded for the 24 months following the second dose by monthly telephone interviews conducted by investigators blinded to the study treatment assignment using standardised questionnaires. During these interviews, the caregivers and the children's pediatricians were questioned about illnesses and the use of antibiotics since the previous telephone call. All of the data were analysed using SAS Windows v.12. Results Among the 1,555 subjects (98.9% who completed the study, analysis of the data by the periods of follow-up demonstrated that radiologically confirmed community-acquired pneumonia (CAP was significantly less frequent in the PCV-7 group during the follow-up as a whole and during the last period of follow-up. Moreover, there were statistically significant between-group differences in the incidence of acute otitis media (AOM in each half-year period of follow-up except the first, with significantly lower number of episodes in children receiving PCV-7 than in controls. Furthermore, the antibiotic prescription data showed that the probability of receiving an antibiotic course was significantly lower in the PCV-7 group than in the control group. Conclusion Our findings show the effectiveness of the simplified

    Full Text Available Testosterone has been identified to play a role in the metabolism of paracetamol in the CD 1 mouse, resulting in differences in renal presentations of male and female mice. Moreover, alterations have been observed in the serum levels of vitamins in male Wistar rats administered with paracetamol/methionine. The aim of this study is to determine if the sex of an animal plays a role in serum vitamin presentation in the Wistar strain after paracetamol/methionine administration. This will be achieved by comparing observation made from this study with an earlier one on male Wistar rats. Moreover, comparison of presentations at the 4th & 16th hours will be carried out, so as to establish how earlier in the course of exposure to paracetamol/methionine vitamin alteration takes place. Female Wistar Rats consisting of eight rats per group were administered with different doses of paracetamol & paracetamol/methionine (5:1 ranging from 350-5000 mg/kg. Results indicate that significant alterations (p<0.05 in the levels of all the vitamins commenced as early as the 4th hour in both paracetamol & paracetamol/methionine administered groups. Moreover, significant alterations in the female rats parallel those of male rats obtained from an earlier study. Evidence from this study when compared with an earlier one indicates that sex probable plays no role on the impact of paracetamol on serum vitamins in Wistar rats.

    We report successful oral administration of insulin entrapped in amidated pectin hydrogel beads in streptozotocin (STZ)-diabetic rats, with a concomitant reduction in plasma glucose concentration. The pectin-insulin (PI) beads were prepared by the gelation of humilin-pectin solutions in the presence of calcium. Separate groups of STZ-diabetic rats were orally administered two PI beads (30 micrograms insulin) once or twice daily or three beads (46 micrograms) once daily for 2 weeks. Control non-diabetic and STZ-diabetic rats were orally administered pectin hydrogel drug-free beads. By comparison with control non-diabetic rats, untreated STZ-diabetic rats exhibited significantly low plasma insulin concentration (0.32+/-0. 03 ng/ml, n=6, compared with 2.60+/-0.44 ng/ml in controls, n=6) and increased plasma glucose concentrations (25.84+/-1.44 mmol/l compared with 10.72+/- 0.52 mmol/l in controls). Administration of two PI beads twice daily (60 micrograms active insulin) or three beads (46 micrograms) once a day to STZ-diabetic rats increased plasma insulin concentrations (0.89+/-0.09 ng/ml and 1.85+/- 0.26 ng/ml, respectively), with a concomitant reduction in plasma glucose concentration (15.45+/-1.63 mmol/l and 10.56+/-0.26 mmol/l, respectively). However, a single dose of PI beads (30 micrograms) did not affect plasma insulin concentrations, although plasma glucose concentrations (17.82+/-2.98 mmol/l) were significantly reduced compared with those in untreated STZ-diabetic rats. Pharmacokinetic parameters in STZ-diabetic rats show that the orally administered PI beads (30 micrograms insulin) were more effective in sustaining plasma insulin concentrations than was s.c. insulin (30 micrograms). The data from this study suggest that this insulin-loaded amidated pectin hydrogel bead formulation not only produces sustained release of insulin, but may also reduce plasma glucose concentration in diabetes mellitus.

    Five experiments were performed to study the effects of the Alpha-adrenoceptor agonists, clonidine and guanfacine, upon spontaneous motor activity in chronically morphine administered DSP4-treated and control rats. DSP4 (2 x 50 mg/kg, with a 10-day interval between injections) and vehicle (distilled water) were injected i.p., on each occasion 30 min after zimeldine (20 mg/kg). Morphine dosages were raised incrementally from 5 mg/kg (Days 1-3), through 10 mg/kg (Days 4-7) and 20 mg/kg (Days 8-14), to 30 mg/kg (Days 15-20). Motor activity testing occurred on Day 21, Day 22 as well as in Experiments II-V, (from 1st morphine injection). DSP4 pretreatment and chronic morphine injections each reduced motor activity during the first 30 min of testing; combined DSP4 and morphine treatment potentiated the hypoactivity. Habituation quotients indicated deficits in habituation to the novel test environment by the Vehicle-morphine (Quoteint2 only) and DSP4-morphine groups. Acute clonidine treatment (0.04 mg/kg s.c.) reduced motor activity during the first 30 min of testing but attenuated or blocked the morphine-induced hypoactivity in DSP4-treated and control rats. During the 60-90 min test period, clonidine, but not guanfacine (0.08 mg/kg), potentiated morphine-induced hyperactivity in control rats; acute clonidine enhanced this effect, whereas acute guanfacine reduced it, in the DSP4-treated rats. The enhanced hyperactivity of morphine-clonidine suggest a cross-sensitivity effect. Naloxone (0.1 mg/kg s.c.), injected after the 1st 30-min of testing, potentiated markely the clonidine-induced elevations of motor activity in morphine-administered control rats; in the DSP4-treated rats, these effects were dramatically potentiated, underlining the cross-sensitivity effect. Acute guanfacine treatment reduced motor activity during the first 30 min of testing but did not attenuate reliably morphine-induced hypoactivity in control or DSP4 rats. Naloxone did not potentiate the

  3. Group Music Training and Children's Prosocial Skills.

    Directory of Open Access Journals (Sweden)

    E Glenn Schellenberg

    Full Text Available We investigated if group music training in childhood is associated with prosocial skills. Children in 3rd or 4th grade who attended 10 months of music lessons taught in groups were compared to a control group of children matched for socio-economic status. All children were administered tests of prosocial skills near the beginning and end of the 10-month period. Compared to the control group, children in the music group had larger increases in sympathy and prosocial behavior, but this effect was limited to children who had poor prosocial skills before the lessons began. The effect was evident even when the lessons were compulsory, which minimized the role of self-selection. The results suggest that group music training facilitates the development of prosocial skills.

    Full Text Available The objective of the study was to examine the relationships between several constructs that were hypothesised to be components underlying psychological wellness and to establish whether there were differences between managerial and non-managerial groups or between Black and White groups in respect of the wellness variables. The Personal Orientation Inventory (POI, Locus of Control Inventory (LOC, Sense of Coherence Scale (SOC, and the Bar-On EQ-I were administered to a random sample of 200 employees of a financial services company. Statistically significant differences were found between the groups on several of the wellness variables with the manager and White groups obtaining higher scores on these variables than their comparison groups. However, in respect of External Locus of Control, the non-manager and Black groups obtained the higher scores. Factor analytic results demonstrated that the wellness variables clustered in two correlated factors (r = 0,43 labeled psychological wellness and self-actualisation.

    Few investigations have been conducted on the disposition and fate of silver nanoparticles (AgNP) in pregnancy. The distribution of a single dose of polyvinylpyrrolidone (PVP)-stabilized AgNP was investigated in pregnant rats. Two sizes of AgNP, 20 and 110 nm, and silver acetate (AgAc) were used to investigate the role of AgNP diameter and particle dissolution in tissue distribution, internal dose and persistence. Dams were administered AgNP or AgAc intravenously (i.v.) (1 mg kg(-1) ) or by gavage (p.o.) (10 mg kg(-1) ), or vehicle alone, on gestation day 18 and euthanized at 24 or 48 h post-exposure. The silver concentration in tissues was measured using inductively-coupled plasma mass spectrometry. The distribution of silver in dams was influenced by route of administration and AgNP size. The highest concentration of silver (μg Ag g(-1) tissue) at 48 h was found in the spleen for i.v. administered AgNP, and in the lungs for AgAc. At 48 h after p.o. administration of AgNP, the highest concentration was measured in the cecum and large intestine, and for AgAc in the placenta. Silver was detected in placenta and fetuses for all groups. Markers of cardiovascular injury, oxidative stress marker, cytokines and chemokines were not significantly elevated in exposed dams compared to vehicle-dosed control. NMR metabolomics analysis of urine indicated that AgNP and AgAc exposure impact the carbohydrate, and amino acid metabolism. This study demonstrates that silver crosses the placenta and is transferred to the fetus regardless of the form of silver. Copyright © 2016 John Wiley & Sons, Ltd.

    This paper reports the results of the first study in which Streptococcus salivarius 24SMB, a safe α-haemolytic strain capable of producing bacteriocin-like substances with significant activity against acute otitis media (AOM) pathogens, was intranasally administered in an attempt to reduce the risk of new episodes of AOM in otitis-prone children. In this prospective, randomized, double-blind, placebo-controlled study, 100 children aged 1-5 years with histories of recurrent AOM were randomized 1:1 to receive an intranasal S. salivarius 24SMB or placebo twice daily for 5 days each month for 3 consecutive months. Fifty treated children and 47 who received placebo who were compliant with study protocol were followed monthly for 6 months. The number of children who did not experience any AOM was higher among the children treated with the S. salivarius 24SMB preparation than among those in the placebo group (30.0 vs 14.9%; p = 0.076). Moreover, the number of children who received antibiotics during the study period was lower among the children treated with S. salivarius 24 SMB than among those who received placebo (70 vs 83.0%; p = 0.13). Compared with the children who were not colonized by S. salivarius 24SMB after treatment, the number of colonized children who experienced any AOM was significantly lower (42.8 vs 13.6%; p = 0.03). Similar results were observed when the children treated with antibiotics for AOM were analysed (67.8 vs 95.5%; p = 0.029). This study revealed the ability of intranasally administered S. salivarius 24SMB to reduce the risk of AOM in otitis-prone children.

    Evaluating and comparing the effectiveness of two smartphone-delivered treatments: one based on behavioural activation (BA) and other on mindfulness. Parallel randomised controlled, open, trial. Participants were allocated using an online randomisation tool, handled by an independent person who was separate from the staff conducting the study. General community, with recruitment nationally through mass media and advertisements. 40 participants diagnosed with major depressive disorder received a BA treatment, and 41 participants received a mindfulness treatment. 9 participants were lost at the post-treatment. An 8-week long behaviour programme administered via a smartphone application. Mindfulness: An 8-week long mindfulness programme, administered via a smartphone application. The Beck Depression Inventory-II (BDI-II) and the nine-item Patient Health Questionnaire Depression Scale (PHQ-9). 81 participants were randomised (mean age 36.0 years (SD=10.8)) and analysed. Results showed no significant interaction effects of group and time on any of the outcome measures either from pretreatment to post-treatment or from pretreatment to the 6-month follow-up. Subgroup analyses showed that the BA treatment was more effective than the mindfulness treatment among participants with higher initial severity of depression from pretreatment to the 6-month follow-up (PHQ-9: F (1, 362.1)=5.2, p<0.05). In contrast, the mindfulness treatment worked better than the BA treatment among participants with lower initial severity from pretreatment to the 6-month follow-up (PHQ-9: F (1, 69.3)=7.7, p<0.01); BDI-II: (F(1, 53.60)=6.25, p<0.05). The two interventions did not differ significantly from one another. For participants with higher severity of depression, the treatment based on BA was superior to the treatment based on mindfulness. For participants with lower initial severity, the treatment based on mindfulness worked significantly better than the treatment based on BA. Clinical Trials

    To compare the pharmacokinetics and pharmacodynamics of propofol with or without 2% benzyl alcohol administered intravenously (IV) as a single induction dose in cats. Prospective experimental study. Six healthy adult cats, three female intact, three male castrated, weighing 4.8 ± 1.8 kg. Cats received 8 mg kg(-1) IV of propofol (P) or propofol with 2% benzyl alcohol (P28) using a randomized crossover design. Venous blood samples were collected at predetermined time points to 24 hours after drug administration to determine drug plasma concentrations. Physiologic and behavioral variables were also recorded. Propofol and benzyl alcohol concentrations were determined using high pressure liquid chromatography with fluorescence detection. Pharmacokinetic parameters were described using a 2-compartment model. Pharmacokinetic and pharmacodynamic parameters were analyzed using repeated measures anova (p cats (33%), and by 30 minutes for the remaining four cats. Propofol pharmacokinetics, with or without 2% benzyl alcohol, were characterized by rapid distribution, a long elimination phase, and a large volume of distribution. No differences were noted between treatments with the exception of clearance from the second compartment (CLD2), which was 23.6 and 38.8 mL kg(-1)  minute(-1) in the P and P28 treatments, respectively. Physiologic and behavioral variables were not different between treatments with the exception of heart rate at 4 hours post administration. The addition of 2% benzyl alcohol as a preservative minimally altered the pharmacokinetics and pharmacodynamics of propofol 1% emulsion when administered as a single IV bolus in this group of cats. These data support the cautious use of propofol with 2% benzyl alcohol for induction of anesthesia in healthy cats. © 2014 Association of Veterinary Anaesthetists and the American College of Veterinary Anesthesia and Analgesia.

    The effects of administration of bifidobacteria on the intestinal microbiota in low-birth-weight infants, and the transition of each strain of administered bifidobacteria were investigated. A single strain of Bifidobacterium breve M-16V (5 × 10(8); one-species group) or a mixture of three species composed of B. breve M-16V, Bifidobacterium longum subsp. infantis M-63 and B. longum subsp. longum BB536 (5 × 10(8) of each strain; three-species group) were administered daily for 6 weeks. Bifidobacterial administration significantly increased the detection rates and cell numbers of bifidobacteria in the feces (weeks 1-6). The proportion of bifidobacteria was significantly higher in the one-species group at weeks 1-4, and in the three-species group at weeks 1-6 compared with the control group. Furthermore, the proportion of bifidobacteria in the three-species group was significantly higher than that in the one-species group at weeks 1 and 6. The proportion of infants with bifidobacteria-predominant microbiota was significantly higher in the three-species group than in the control group during the test period. The detection rates of Clostridium were lower in the bifidobacteria-administered groups. The proportions of Enterobacteriaceae were significantly lower in the three-species group compared to the other groups (weeks 4 and 6). Among the three strains administered, B. breve M-16V and Bifidobacterium infantis M-63 were detected in 85% or more of the infants during the administration period, while B. longum BB536 was detected in 40% or less. Compared with administration of one species, administration of three species of bifidobacteria resulted in earlier formation of a bifidobacteria-predominant fecal microbiota and maintenance of this microbiota.

    Over the course of childhood, children's thinking about social groups changes in a variety of ways. Developmental Subjective Group Dynamics (DSGD) theory emphasizes children's understanding of the importance of conforming to group norms. Abrams et al.'s study, which uses DSGD theory as a framework, demonstrates the social cognitive skills underlying young elementary school children's thinking about group norms. Future research on children's thinking about groups and group norms should explore additional elements of this topic, including aspects of typicality beyond loyalty.

    1997-04-01

    We surveyed the literatures and discussed the legal issues whether we should administer blood for lifesaving to a patient who refuses it. The valid refusal of the transfusion requires the distinct intention of a competent patient. Minors below fifteen years of age are incompetent and their parents make a substituted judgement. Anyone must not give priority to the parents' belief and blood ought to be transfused if necessary for the children's benefits. We could evade liability for withholding blood only when we manage an operation arranged to succeed without blood transfusion, undergoing the sufficient treatments to avoid the risks, as well as on the basis of the valid refusal of a patient. The release deed and the intervention of hospital directors, ethics committees and courts are invalid for the immunity from liability. Anesthesiologists have to take the responsibility on themselves of administering blood or not. A statute law should be established to define what is a patient's valid intention and who is responsible.

    The feasibility of administering the pain reliever acetaminophen to rats via their water bottles was examined in this study. Two different preparations of acetaminophen were used, a cherry-flavored suspension and an alcohol-containing solution. Both preparations of acetaminophen were diluted to 6 mg/ml by using normal drinking water. When healthy unmanipulated rats were exposed to either of the acetaminophen preparations for the first time, the animals showed a dramatic reduction in fluid intake. A marked reduction in food intake also was associated with the cherry-flavored preparation. These reductions appear to be an expression of the well-characterized neophobic response that can be demonstrated by rodents when they encounter a novel taste. This neophobic behavior suggests that administering pain relievers to rats via their drinking water is counterproductive as a means of providing pain relief.

  15. Repetitive immunization enhances the susceptibility of mice to peripherally administered prions.

    Directory of Open Access Journals (Sweden)

    Juliane Bremer

    Full Text Available The susceptibility of humans and animals to prion infections is determined by the virulence of the infectious agent, by genetic modifiers, and by hitherto unknown host and environmental risk factors. While little is known about the latter two, the activation state of the immune system was surmised to influence prion susceptibility. Here we administered prions to mice that were repeatedly immunized by two initial injections of CpG oligodeoxynucleotides followed by repeated injections of bovine serum albumin/alum. Immunization greatly reduced the required dosage of peripherally administered prion inoculum necessary to induce scrapie in 50% of mice. No difference in susceptibility was observed following intracerebral prion challenge. Due to its profound impact onto scrapie susceptibility, the host immune status may determine disease penetrance after low-dose prion exposure, including those that may give rise to iatrogenic and variant Creutzfeldt-Jakob disease.

    Leber's hereditary optic neuropathy (LHON) is an inherited disorder affecting the retinal ganglion cells (RGCs) and their axons that lead to the loss of central vision. This study is aimed at evaluating the LHON symptoms in rats administered with rotenone microspheres into the superior colliculus (SC). Optical coherence tomography (OCT) analysis showed substantial loss of retinal nerve fiber layer (RNFL) thickness in rotenone injected rats. Optokinetic testing in rotenone treated rats showed decrease in head-tracking response. Electrophysiological mapping of the SC surface demonstrated attenuation of visually evoked responses; however, no changes were observed in the ERG data. The progressive pattern of disease manifestation in rotenone administered rats demonstrated several similarities with human disease symptoms. These rats with LHON-like symptoms can serve as a model for future investigators to design and implement reliable tests to assess the beneficial effects of therapeutic interventions for LHON disease.

    Urocortin 3 (Ucn3) is recognized as a member of the corticotropin-releasing factor (CRF) family, which plays an important role in regulating food intake. We investigated the effects of centrally administered Ucn3 on food intake and gastric emptying in mice. Intracerebroventricular (ICV)administration of Ucn3 (0.1–1 nmol per mouse) decreased food intake in a dose-dependent manner. The inhibitory effect of Ucn3 on food intake was less potent than that of centrally administered CRF and Urocortin 1. ICV administration of Ucn3 (0.1–1 nmol per mouse) decreased the gastric emptying rate in a dose-dependent manner. Ucn3 decreased food intake in high-fat diet-fed obese mice as well as in lean mice. These results indicated that Ucn3 influences feeding behavior and gut motility, and may be a promising therapeutic target in the treatment of eating and functional gastrointestinal disorders.

    Little is known regarding how cognitive strategies help to modulate neural responses of the human brain in ongoing pain syndromes to alleviate pain. Under pathological pain conditions, any self-elicited contact with usually non-painful stimuli may become painful. We examined whether the human brain is capable of dissociating self-controlled from externally administered thermal hyperalgesia in the experimental capsaicin model. Using functional magnetic resonance imaging, 17 male subjects were investigated in a parametric design with heat stimuli at topically capsaicin-sensitized skin. In contrast to external stimulation, self-administered pain was controllable. For both conditions application trials without noticeable thermal stimulation were introduced and used as high-level baseline (HLB) to account for the capsaicin-induced ongoing pain and other covariables. Following subtraction of the HLB, the anterior insula and the anterior cingulate cortex (ACC) but not the somatosensory cortices maintained parametric neural responses to thermal hyperalgesia. A stronger pain-related activity increase during self-administered stimuli was observed in the posterior insula. In contrast, prefrontal cortex showed stronger increases to uncontrollable external heat stimuli. In the state of ongoing pain (capsaicin), pain-intensity-encoding regions (anterior insula, ACC) but not those with sensory discriminative functions (SI, SII) showed graded, pain-intensity-related neural responses in thermal hyperalgesia. Some areas were able to dissociate between self- and externally administered stimuli in thermal hyperalgesia, which might be related to differences in perceived controllability. Thus, neural mechanisms maintain the ability to dissociate external from self-generated states of injury in thermal hyperalgesia. This may help to understand how cognitive strategies potentially alleviate chronic pain syndromes.

  20. Influence of emotional stress on pharmacokinetics of isosorbide dinitrate intraperitoneally administered to rats.

    Full Text Available The plasma level of isosorbide dinitrate intraperitoneally administered to rats stressed by foot-shock was almost the same as that in non-stressed control rats. However, levels of its metabolites, 5-isosorbide mononitrate and 2-isosorbide mononitrate, were lower in stressed rats than in non-stressed rats, suggesting that stress may influence the metabolism and/or excretion of the metabolites.

    Using the Faces Pain Scale - Revised, we assessed injection site pain 10 minutes after vaccination in young females randomized to receive either quadrivalent human papillomavirus vaccine (HPV4) before or after concomitantly administered vaccines. Although pain was modestly more after HPV4 injection than after other vaccines, the pain intensity after HPV4 injection was significantly less in those who received HPV4 before receiving other concomitant vaccines.

    The narcotic antagonist naloxone does not antagonize antinociception elicited in the rabbit by 100 microgram/kg of mescaline centrally administered, whereas pretreatment with 6-hydroxydopamine (6-OHDA) inhibits this mescaline effect. Stereotyped behavior of rabbits following central mescaline administration is also prevented by 6-hda pretreatment. Since 6-OHDA in known to produce a degeneration of catecholamine containing nerve terminals, a crucial role of catecholamines is suggested in the complex of effects seen in the rabbit after central administration of the hallucinogen.

    Brain perfusion imaging by means of 99mTc-HMPAO is widely used in the diagnosis of Alzheimer's disease. The administered dose range recommended by the manufacturer and reported in bibliography is rather wide (~ 9.5 - 27 mCi), necessitating further quantitative analysis. In the framework of this study, a quantitative evaluation of the radiopharmaceutical performance for different values of administered dose was carried out, based on image quality indicators. Evaluation of image quality was based on wavelet-generated contrast, noise, and contrast-to-noise ratio indicators, denoted as CI, NI and CNR respectively. Subsequently, a generic image quality index was correlated with the administered dose, to produce an overall performance indicator (denoted as PI). Application of appropriate statistical tests (analysis of variance for normal and Kruskal-Wallis test for non-normal distributions) showed that there is a statistically significant difference in CI (p 0.05) values. Application of Tukey test for CI and NI normal distributions demonstrated that CI (10 mCi) = CI (20 mCi) NI (20 mCi), while NI (15 mCi) could not be characterised. Finally, application of non-parametric multiple comparisons showed that CNR (20 mCi) < CNR (10 mCi), while CNR (15 mCi) could not be characterised. Consequently, brain perfusion imaging, by means of 99mTc-HMPAO utilising an administered dose of 20 mCi, results in improved image quality on the basis of the estimated indicators. Additionally, this image quality improvement is sufficient to justify the increased patient radiation burden.

    Introduction Select units in the military have improved combat medic training by integrating their functions into routine clinical care activities with measurable improvements in battlefield care. This level of integration is currently limited to special operations units. It is unknown if regular Army units and combat medics can emulate these successes. The goal of this project was to determine whether US Army combat medics can be integrated into routine emergency department (ED) clinical care, specifically medication administration. Project Design This was a quality assurance project that monitored training of combat medics to administer parenteral medications and to ensure patient safety. Combat medics were provided training that included direct supervision during medication administration. Once proficiency was demonstrated, combat medics would prepare the medications under direct supervision, followed by indirect supervision during administration. As part of the quality assurance and safety processes, combat medics were required to document all medication administrations, supervising provider, and unexpected adverse events. Additional quality assurance follow-up occurred via complete chart review by the project lead. Data During the project period, the combat medics administered the following medications: ketamine (n=13), morphine (n=8), ketorolac (n=7), fentanyl (n=5), ondansetron (n=4), and other (n=6). No adverse events or patient safety events were reported by the combat medics or discovered during the quality assurance process. In this limited case series, combat medics safely administered parenteral medications under indirect provider supervision. Future research is needed to further develop this training model for both the military and civilian setting. Schauer SG , Cunningham C W, Fisher AD , DeLorenzo RA .

    A fecal microbiota transplant has proved to be an extremely effective method for patients with recurrent infections with Clostridium difficile. We present the case of a 65-year-old female patient with multiple Clostridium difficile infection (CDI) relapses on the rectal remnant, post-colectomy for a CDI-related toxic megacolon. The patient also evidenced associated symptomatic Clostridium difficile vaginal infection. She was successfully treated with serial fecal "minitransplants" (self-administered at home) and metronidazole ovules.

    The aim of this study was to establish a method for determining administered activities for {sup 68}Ga-labelled peptides. Dose calculations were based on the weight-independent effective dose model proposed by the EANM paediatric dosage card for use in paediatric nuclear medicine. Previously published time-integrated activity coefficients for {sup 68}Ga-DOTATATE, {sup 68}Ga-DOTATOC and {sup 68}Ga-pentixafor were used to calculate age-independent effective doses. Consequently, the corresponding weight-dependent effective dose coefficients were rescaled according to the formalism of the EANM dosage card to determine the radiopharmaceutical class of {sup 68}Ga-labelled peptides (''multiples'') and to calculate the baseline activities based on an upper limit for administered activity (185 MBq) in an adult. All calculated normalization factors suggest that the {sup 68}Ga-labelled peptides are class ''B'' radiopharmaceuticals. The baseline activity for all compounds is 12.8 MBq. In analogy to {sup 18}F-fluoride, we recommend a minimum activity of 14 MBq. For paediatric nuclear medicine applications involving {sup 68}Ga-labelled peptides, we suggest determining administered activities based on the formalism proposed in this work. The corresponding effective doses from these procedures will remain age-independent. (orig.)

    Full Text Available Lipopolysaccharide (LPS has been associated with adverse pregnant outcomes, including fetal demise, intra-uterine growth restriction (IUGR, neural tube defects (NTDs and preterm delivery in rodent animals. Previous studies demonstrated that melatonin protected against LPS-induced fetal demise, IUGR and preterm delivery. The aim of the present study was to investigate the effects of melatonin on LPS-induced NTDs. All pregnant mice except controls were intraperitoneally injected with LPS (25 µg/kg daily from gestational day (GD8 to GD12. Some pregnant mice were orally administered with melatonin (MT, 50 mg/kg before each LPS injection. A five-day LPS injection resulted in 27.5% of fetuses with anencephaly, exencephaly or encephalomeningocele. Additional experiment showed that maternal LPS exposure significantly down-regulated placental proton-coupled folate transporter (pcft and disturbed folate transport from maternal circulation through the placentas into the fetus. Interestingly, melatonin significantly attenuated LPS-induced down-regulation of placental pcft. Moreover, melatonin markedly improved the transport of folate from maternal circulation through the placentas into the fetus. Correspondingly, orally administered melatonin reduced the incidence of LPS-induced anencephaly, exencephaly or encephalomeningocele. Taken together, these results suggest that orally administered melatonin prevents LPS-induced NTDs through alleviating LPS-induced disturbance of folate transport from maternal circulation through the placenta into the fetus.

    Full Text Available We compared the kinetic behaviour of tylosin administered to beehives by dusting or paper-pack placement through three treatment protocols (D, PP, CONTROL. D (dusting: tylosin, divided in four portions, was sprinkled over the ends of the hives' top bars weekly for four weeks (n=3; PP (paper-pack placement: tylosin in paper packs was administered at two-week intervals (n=3; CONTROL (control: the hives were left untreated (n=3. In every inspection, from each of the nine hives, fifty young (2-day-old larvae were sampled for drug analysis. The concentration of tylosin in the young larvae was determined by a microbiological assay with Geobacillus stearothermophilus ATCC 12980 as test organism. The (mean±SD maximum concentration (Cmax for D was 136.0±194.0 and for PP – 144.0±187.4 µg/mL; the time to reach Cmax (tmax was 1.5±0.9 h for D and 1.8 ± 1.8 h for PP. The area under the tylosin behaviour kinetics curve between 0–1392 h with D was 308.7±185.2 and with PP: 326.4±141.0 µg/h/mL, indicating no statistical difference between the treatments (P>0.05. The shorter duration of paper-pack-administered tylosin observed in the larvae implied a lower risk of antibiotic residues in the resulting honey

    A recombinant bactericidal protein, recombinant lysostaphin (r-lysostaphin), that may be useful as an intramammary therapeutic for Staphylococcus aureus mastitis in dairy cattle, was evaluated for immunogenicity to various hosts. Although immunogenicity could be demonstrated in a variety of other species when administered parenterally, oral administration failed to elicit a significant immunological response. Similarly, intramammary infusion of r-lysostaphin failed to elicit significant serum titers in the bovine until 18-21 infusions were administered (total administered dose of 2-3 g of protein). Antibody titers from dairy cattle which did develop an immune response were predominantly of the IgG1 subclass. Dairy cattle with significant anti-lysostaphin titers showed no deleterious symptoms (anaphylaxis, etc.) upon subsequent infusion, and these titers did not effect the in vitro bacteriostatic activity of r-lysostaphin. Intramammary infusion of r-lysostaphin does not elicit any observable effects on the host animal or on the potential efficacy of the recombinant molecule. Intramammary recombinant proteins may be suitable effective and safe infusion products that provide an alternative to classical antibiotic therapy.

    Diethylenetriaminepentaacetic acid (DTPA) is an effective decorporation agent to facilitate the elimination of radionuclides from the body, but its permeability-limited oral bioavailability limits its utility in mass-casualty emergencies. To overcome this limitation, a prodrug strategy using the penta-ethyl ester form of DTPA is under investigation. Pharmacokinetic and biodistribution studies were conducted in rats by orally administering [(14) C]DTPA penta-ethyl ester, and this prodrug and its hydrolysis products were analyzed as a single entity. Compared with a previous reporting of intravenously administered DTPA, the oral administration of this prodrug resulted in a sustained plasma concentration profile with higher plasma exposure and lower clearance. An assessment of the urine composition revealed that the bioactivation was extensive but incomplete, with no detectable levels of the penta- or tetra-ester forms. Tissue distribution at 12 h was limited, with approximately 73% of the administered dose being associated with the gastrointestinal tract. In the efficacy study, rats were exposed to aerosols of (241) Am nitrate before receiving a single oral treatment of the prodrug. The urinary excretion of (241) Am was found to be 19% higher than with the control. Consistent with prior reports of DTPA, the prodrug was most effective when the treatment delays were minimized. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association.

    This pilot project explored the feasibility, safety, and effectiveness of a self-administered exercise and stress management intervention for cancer patients receiving chemotherapy. Thirty-nine of 56 eligible patients (acceptance =69%) with a variety of solid tumors volunteered for the study. Participants were advised to exercise 20-40 min at 50-75% estimated heart rate reserve 3-5 times per week. In addition, patients were provided with instruction and written materials regarding stress management techniques. Follow-up data were collected during regularly scheduled outpatient visits at the start of the second, third, and fourth chemotherapy cycles using diary entries and the same questionnaires previously administered at baseline. Twenty-four of 39 patients (62%) completed all study requirements. These participants completed 438 of the 678 exercise sessions assigned (adherence =62%). Of the stress management techniques, positive thinking most practiced most frequently (48%), followed by deep breathing (38%) and active relaxation (37%). Paired t tests, comparing baseline values with final recorded values, indicated a significant improvement over time in bodily pain (p<0.03) and mental health (p<0.04) subscale scores. Participants' evaluations of the combined intervention were favorable: 90% felt it was helpful to them and 100% would recommend it to another patient. A self-administered intervention combining aerobic exercise and stress management was acceptable and safe for cancer patients receiving chemotherapy. Preliminary data demonstrating intervention efficacy should be confirmed in subsequent randomized clinical trials.

    Full Text Available Introduction: The concept of maintenance therapy is one of the highly relevant approaches in the management of advanced ovarian cancer. The fundamental goal of maintenance therapy is to improve survival outcomes. We attempted to reinforce maintenance chemotherapy by adding oral etoposide following taxane administration. Cases: We retrospectively evaluated 14 patients with advanced ovarian cancer who had achieved clinically defined complete response to a primary platinum/taxane chemotherapy regimen and who were administered oral etoposide (50 mg/day × 21 days per cycle monthly for 3-5 cycles following paclitaxel or docetaxel administration as maintenance chemotherapy. With regard to oral etoposide toxicity, grade 2 oral mucositis and grade 3 anemia were observed in 1 patient each. Three to five cycles of etoposide were administered to all patients, though daily dosage was reduced to 25 mg in 2 patients due to toxicity. The median progression-free survival was 43.5 months, the median overall survival was 86 months, and 5-year overall survival was 77.1%. Conclusion: The results from this ovarian cancer treatment evaluation suggest that oral etoposide may be administered safely following paclitaxel or docetaxel as maintenance chemotherapy. We expect this regimen to contribute to the improvement in the survival outcomes of patients with advanced ovarian cancer.

    Aphasia is a chronic condition that usually requires long-term rehabilitation. However, even if many effective treatments can be offered to patients and families, speech therapy services for individuals with aphasia often remain limited because of logistical and financial considerations, especially more than 6 months after stroke. Therefore, the need to develop tools to maximize rehabilitation potential is unquestionable. The aim of this study was to test the efficacy of a self-administered treatment delivered with a smart tablet to improve written verb naming skills in CP, a 63-year-old woman with chronic aphasia. An ABA multiple baseline design was used to compare CP's performance in verb naming on three equivalent lists of stimuli trained with a hierarchy of cues, trained with no cues, and not trained. Results suggest that graphemic cueing therapy, done four times a week for 3 weeks, led to better written verb naming compared to baseline and to the untrained list. Moreover, generalization of the effects of treatment was observed in verb production, assessed with a noun-to-verb production task. Results of this study suggest that self-administered training with a smart tablet is effective in improving naming skills in chronic aphasia. Future studies are needed to confirm the effectiveness of new technologies in self-administered treatment of acquired language deficits.

    Dietary collagen hydrolysate has been hypothesized to improve skin barrier function. To investigate the effect of long-term collagen hydrolysate administration on the skin, we evaluated stratum corneum water content and skin elasticity in intrinsically aged mice. Female hairless mice were fed a control diet or a collagen hydrolysate-containing diet for 12 wk. Stratum corneum water content and skin elasticity were gradually decreased in chronologically aged control mice. Intake of collagen hydrolysate significantly suppressed such changes. Moreover, we used DNA microarrays to analyze gene expression in the skin of mice that had been administered collagen hydrolysate. Twelve weeks after the start of collagen intake, no significant differences appeared in the gene expression profile compared with the control group. However, 1 wk after administration, 135 genes were upregulated and 448 genes were downregulated in the collagen group. This suggests that gene changes preceded changes of barrier function and elasticity. We focused on several genes correlated with functional changes in the skin. Gene Ontology terms related to epidermal cell development were significantly enriched in upregulated genes. These skin function-related genes had properties that facilitate epidermal production and differentiation while suppressing dermal degradation. In conclusion, our results suggest that altered gene expression at the early stages after collagen administration affects skin barrier function and mechanical properties. Long-term oral intake of collagen hydrolysate improves skin dysfunction by regulating genes related to production and maintenance of skin tissue.

    We carried out a retrospective investigation on the effect of obesity on dexmedetomidine (DEX) requirements when administered with fentanyl (FEN) during mechanical ventilation after major surgeries. After Institutional Review Board approval, 14 obese patients with a body mass index (BMI) ≥ 30 kg/m(2) and the same number of non-obese patients with similar backgrounds to the obese patients were selected from medical records. Doses of DEX in the first 48 h or until the end of sedation or extubation were calculated for comparison. In addition to comparison of dosing between the groups, associations between total body weight (TBW), BMI, and lean body mass (LBM) values and doses of DEX (mcg/h), between BMI and various indices (i.e., amount per TBW per hour and amount per LBM per hour) of DEX doses, and between above indices of DEX and FEN doses were also examined. There were no significant differences in DEX dose indices between the groups. However, DEX requirements (mcg/h) were significantly increased with TBW (kg) (r = 0.51, P = 0.003), BMI (r = 0.49, P = 0.006) and LBM (kg) (r = 0.42, P = 0.02), which might have enhanced the DEX metabolism with physiological changes with obesity. These findings will be beneficial for future clinical pharmacological analysis of DEX.

    Neonatal effects of drugs administered to mothers before delivery depend on the quantity that crosses the placental barrier, which is determined by the pharmacokinetics of the drug in the mother, fetus, and placenta. Diabetes mellitus can alter the kinetic disposition and the metabolism of drugs. This study investigated the placental transfer of lidocaine and its metabolite monoethylglycinexylidide (MEGX) in pregnant women with gestational diabetes mellitus (GDM) submitted to peridural anesthesia. A total of 10 normal pregnant women (group 1) and 6 pregnant women with GDM (group 2) were studied, all at term. The patients received 200 mg 2% lidocaine hydrochloride by the peridural locoregional route. Maternal blood samples were collected at the time of delivery and, after placental expulsion, blood samples were collected from the intervillous space, umbilical artery, and vein for determination of lidocaine and MEGX concentrations and analysis of the placental transfer of the drug. The following respective lidocaine ratios between the maternal and the fetal compartments were obtained for groups 1 and 2: umbilical vein/maternal peripheral blood, 0.60 and 0.46; intervillous space/maternal blood, 1.01 and 0.88; umbilical artery/umbilical vein, 0.77 and 0.91; and umbilical vein/intervillous space, 0.53 and 0.51. The following MEGX ratios for groups 1 and 2 were, respectively, fetal/maternal, 0.43 and 0.97; intervillous space/maternal blood, 0.64 and 0.90; umbilical artery/umbilical vein, 1.09 and 0.99; and umbilical vein/intervillous space, 0.55 and 0.78. Gestational diabetes mellitus did not affect the transplacental transfer of lidocaine but interfered with the transfer of MEGX, acting as a mechanism facilitating the transport of the metabolite. © The Author(s) 2015.

    To investigate DBC2 mutations in breast cancer patients and evaluate the relationship between gene mutations and breast cancer susceptibility in an Eastern China population. Mutation analyses of 285bp promoter sequence, coding exon 7 and its exon/intron boundaries of DBC2 were performed in 32 breast cancer specimens by polymerase chain reaction and direct sequencing. Eighteen benign breast tumor specimens were also analyzed as control. No mutation in the promoter or exon 7 was found in either group. An intronic alteration (IVS7+53C>G) was detected in 13 specimens. There was no significant difference in the rate of IVS7+53C>G alteration between the study and control groups (8/32 vs 5/18, respectively, P>0.05). The G allele of IVS7+53 was correlated with HER2 and p53 expression (P0.05). Mutation in the promoter and exon 7 of DBC2 gene is not common in the Chinese population and may not contribute to the susceptibility for breast cancer in China. The intronic alteration IVS7+53C>G is a common polymorphism in the Chinese Han ethnic group. Further research is warranted to evaluate the relationship between IVS7+53C>G and the susceptibility for breast cancer. Copyright © 2014. Published by Elsevier B.V.

    Modern technology puts into question the effectiveness of using pen and paper as a means of collecting information from web-enabled patients. This study aimed to validate and test the reliability of using the Internet as a method of administering health-related quality of life questionnaires in a pediatric spine population. A prospective randomized crossover study was conducted. Patients aged 11 to 18 with idiopathic scoliosis were invited to participate, and informed consent was obtained from a scoliosis outpatient clinic setting. Participants were randomized to one of 4 groups determining the method of questionnaire administration [Scoliosis Research Society 30 (SRS-30) and Pediatric Outcomes Data Collection Instrument (PODCI)]. Both questionnaires were completed at 2 separate timepoints and 2 weeks apart to prevent recall bias. Groups included: Paper/Paper, Paper/Internet, Internet/Paper, and Internet/Internet. Paired-samples t tests were used to determine the test-retest reliability of each group. Analysis was stratified for surveys returned within or outside of the allotted 4-week timeframe following enrollment. Of the 96 participants who completed and returned both sets of questionnaires, 26 were allocated to the Paper/Paper group (27%), 20 to the Paper/Internet group (21%), 26 to the Internet/Paper group (27%), and 24 to the Internet/Internet group (25%). The second iteration of questionnaires was returned on time by 69 of the participants (71.2%). Of the late questionnaires, 18 (67%) were paper forms. Overall, no differences were observed between Internet-administered compared with pen and paper-administered questionnaires (P=0.206). No differences were observed within any group individually for either the SRS-30 or PODCI questionnaire. In addition, no significant differences were observed within groups for surveys returned within or outside of the 4-week timeframe.

  5. Hilbert modules associated to parabolically induced representations of semisimple Lie groups

    Clare, Pierre

    2009-01-01

    Given a measured space X with commuting actions of two groups G and H satisfying certain conditions, we construct a Hilbert C*(H)-module E(X) equipped with a left action of C*(G), which generalises Rieffel's construction of inducing modules. Considering G to be a semisimple Lie group and H to be the Levi component L of a parabolic subgroup P=LN, the Hilbert module associated to X=G/N encodes the P-series representations of G coming from parabolic subgroups associated to P. We provide several descriptions of this Hilbert module, corresponding to the classical pictures of P-series. We then characterise the bounded operators on E(G/N) that commute to the left action of C*(G) as central multipliers of C*(L) and interpret this result as a globalised generic irreducibility theorem. Finally, we establish the convergence of intertwining integrals on a dense subset of E(G/N).

  10. Group theories: relevance to group safety studies.

    Science.gov (United States)

    Benevento, A L

    1998-01-01

    Promoting safety in the workplace has been attempted in a variety of ways. Increasingly, industries are using groups such as safety teams and quality circles to promote worker safety. Group influences on individual behavior and attitudes have long been studied in the social psychology literature, but the theories have not been commonly found outside the psychology arena. This paper describes the group theories of group polarization, risky shift, social loafing, groupthink and team think and attempts to apply these theories to existing studies that examine work group influences on safety. Interesting parallels were found but only one study examined group influences as their primary focus of research. Since groups are increasingly used for safety promotion, future research on safety that studies group influences with respect to current group theories is recommended.

    In order to evaluate the immunogenicity, safety and tolerability of the 2009 A/H1N1 MF59-adjuvanted influenza vaccine administered sequentially or simultaneously with seasonal virosomal-adjuvanted influenza vaccine to HIV-infected children and adolescents, 36 HIV-infected children and adolescents, and 36 age- and gender-matched healthy controls were randomised 1:1 to receive the pandemic vaccine upon enrollment and the seasonal vaccine one month later, or to receive the pandemic and seasonal vaccines simultaneously upon enrollment. Seroconversion and seroprotection rates against the pandemic influenza A/H1N1 virus were 100% two months after vaccine administration in both groups, regardless of the sequence of administration. Geometric mean titres against pandemic and seasonal antigens were significantly higher when the seasonal and pandemic vaccines were administered simultaneously than when the seasonal vaccine was administered alone. Local and systemic reactions were mild and not increased by simultaneous administration. In conclusion, the 2009 pandemic influenza A/H1N1 MF59-adjuvanted vaccine is as immunogenic, safe and well tolerated in HIV-infected children and adolescents as in healthy controls. Its simultaneous administration with virosomal-adjuvanted seasonal antigens seems to increase immune response to both pandemic and seasonal viruses with the same safety profile as that of the pandemic vaccine alone. However, because this finding cannot be clearly explained by an immunological viewpoint, further studies are needed to clarify the reasons of its occurrence. Copyright © 2010 Elsevier Ltd.

    The fate of carbamazepine after intravenous injection in rats (n = 24) and the influence of activated charcoal on the kinetics was investigated. After randomization to four groups (n = 6, each), plasma concentration and the quantities of carbamazepine and metabolites excreted into bile, urine and intestine were determined using an in situ perfusion model of the small intestine (Ringer's solution) with or without orally administered activated charcoal (AC+; AC-) and with or without bile duct cannulation (BD+; BD-). The cumulative amount of carbamazepine and metabolites exsorbed into the small intestine within 3.5 hr after intravenous injection was about 15% in BD- animals and about 3% in BD+ animals. About 20% of the dose was detected in the externalized bile. Activated charcoal did not influence the amount exsorbed into the small intestine. Terminal half-life in plasma ranged from 159 min. to 194 min. within the four treatment groups without statistical significant difference (P = 0.751). Correspondingly, the area under the curve did not vary significantly and ranged between 1.13 and 1.41 g/min./l (P = 0.378). Excretion of carbamazepine and metabolites into urine varied between 3% and 6% of dose within all groups and showed close correlation with diuresis. In an identical experimental approach using a 2-fold intestinal perfusion rate (50 ml/hr; n = 8), no fundamental changes compared to the main experiment regarding pharmacokinetics of carbamazepine were observed. The lack of effect of activated charcoal on the elimination of carbamazepine and metabolites must be contributed to the small amount of the drug being exsorbed into the intestine and may be further influenced by reduced intestinal permeability of carbamazepine and metabolites or inadequate luminal stirring.

    To model the plasma tetracycline concentrations in swine (Sus scrofa domestica) treated with medication administered in water and determine the factors that contribute to the most accurate predictions of measured plasma drug concentrations. Plasma tetracycline concentrations measured in blood samples from 3 populations of swine. Data from previous studies provided plasma tetracycline concentrations that were measured in blood samples collected from 1 swine population at 0, 4, 8, 12, 24, 32, 48, 56, 72, 80, 96, and 104 hours and from 2 swine populations at 0, 12, 24, 48, and 72 hours hours during administration of tetracycline hydrochloride dissolved in water. A 1-compartment pharmacostatistical model was used to analyze 5 potential covariate schemes and determine factors most important in predicting the plasma concentrations of tetracycline in swine. 2 models most accurately predicted the tetracycline plasma concentrations in the 3 populations of swine. Factors of importance were body weight or age of pig, ambient temperature, concentration of tetracycline in water, and water use per unit of time. The factors found to be of importance, combined with knowledge of the individual pharmacokinetic and chemical properties of medications currently approved for administration in water, may be useful in more prudent administration of approved medications administered to swine. Factors found to be important in pharmacostatistical models may allow prediction of plasma concentrations of tetracycline or other commonly used medications administered in water. The ability to predict in vivo concentrations of medication in a population of food animals can be combined with bacterial minimum inhibitory concentrations to decrease the risk of developing antimicrobial resistance.

    Anorectal procedures are often performed in an outpatient setting using a variety of anesthetic techniques. One technique that has not been well studied is surgeon-administered conscious sedation along with local anesthetic. The purpose of this study was to evaluate the use of this technique with emphasis on safety, efficacy, and patient satisfaction. Chart review was performed on 133 consecutive patients who had anorectal procedures at an outpatient surgery center. Additionally, 65 patients were enrolled prospectively and completed a satisfaction survey. Inclusively, charts of 198 patients who underwent outpatient anorectal surgery under conscious sedation and local anesthesia under the direction of a colorectal surgeon from 2004 through 2008 were reviewed. Parameters related to patient and procedural characteristics, safety, efficacy, and satisfaction were evaluated. Surgeon-administered sedation consisted of combined fentanyl and midazolam in 90 per cent. Eighty per cent of procedures were performed in the prone position and 23 per cent were in combination with an endoscopic procedure. Eighty-two per cent were classified as American Society of Anesthesiologists Grade 1 or 2. Transient mild hypoxemia or hypotension occurred in 4 and 3 per cent of the patients, respectively. Mean operative time was 29 minutes with a mean stay in the postanesthesia care unit of 37 minutes. There were no early major cardiac or respiratory complications. Ninety-seven per cent of the patients surveyed reported a high degree of satisfaction. Surgeon-administered conscious sedation with local anesthesia was well tolerated for outpatient anorectal surgeries. Additional studies are needed to confirm the safety and efficacy of this technique.

    Full Text Available Abstract Background Patient-reported outcomes are measured in many epidemiologic studies using self- or interviewer-administered questionnaires. While in some studies differences between these administration formats were observed, other studies did not show statistically significant differences important to patients. Since the evidence about the effect of administration format is inconsistent and mainly available from cross-sectional studies our aim was to assess the effects of different administration formats on repeated measurements of patient-reported outcomes in participants with AIDS enrolled in the Longitudinal Study of Ocular Complications of AIDS. Methods We included participants enrolled in the Longitudinal Study of Ocular Complications in AIDS (LSOCA who completed the Medical Outcome Study [MOS] -HIV questionnaire, the EuroQol, the Feeling Thermometer and the Visual Function Questionnaire (VFQ 25 every six months thereafter using self- or interviewer-administration. A large print questionnaire was available for participants with visual impairment. Considering all measurements over time and adjusting for patient and study site characteristics we used linear models to compare HRQL scores (all scores from 0-100 between administration formats. We defined adjusted differences of ≥0.2 standard deviations [SD] to be quantitatively meaningful. Results We included 2,261 participants (80.6% males with a median of 43.1 years of age at enrolment who provided data on 23,420 study visits. The self-administered MOS-HIV, Feeling Thermometer and EuroQol were used in 70% of all visits and the VFQ-25 in 80%. For eight domains of the MOS-HIV differences between the interviewer- and self- administered format were Conclusions Our large study provides evidence that administration formats do not have a meaningful effect on repeated measurements of patient-reported outcomes. As a consequence, longitudinal studies may not need to consider the effect of

    Full Text Available Background: Physician counseling on the risks of tobacco smoking and the benefits of cessation has been shown to be an effective method of increasing the rate of smoking cessation. Using the "Help Your Patients Quit Smoking: A Coaching Guide" also referred to as the "7A′s of Smoking Cessation" guideline from the New York City Department of Health and Mental Hygiene is thought to be effective to convey the importance of smoking cessation. Aim: To study the efficacy of the "7A′s of Smoking Cessation" guideline counseling conducted by osteopathic medical students. Materials and Methods: Osteopathic medical students were trained to counsel smokers for 3-10 min based on New York City Department of Health′s "7A′s of Smoking Cessation" guidelines by a licensed physician. Students then counseled health fair participants who were cigarette smokers for 3-10 min. Postcounseling, participants were administered an 4 question survey to evaluate the effect counseling had on their desire to quit smoking. Survey data were collected and analyzed. Institutional Review Board approval was obtained for this study. Results: A total of 13 anonymous health fair participants who were also smokers were administered both counseling sessions and surveys. 11/13 (84.6% participants stated that the session motivated them to quit smoking. 9/13 (69.2% participants responded that they were now motivated to discuss smoking cessation with their doctor after being counseled. Of these participants 12/13 (92.3% had previously attempted to quit smoking without success. Conclusion: Participants reported an increased willingness to stop smoking after being counseled by osteopathic medical students. Participants also reported an increased motivation to discuss smoking cessation with their physician. These findings indicate that smoking cessation counseling administered by osteopathic medical students effectively in encouraging smokers to consider reduction or cessation of tobacco

    Tralokinumab, administered as two 1-mL subcutaneous injections every 2 weeks, at the target dose 300 mg, has been shown to improve lung function in patients with asthma. This study evaluated the pharmacokinetic (PK) and tolerability profile of tralokinumab 300 mg when administered by different rates of subcutaneous injection, as part of a pilot investigation of new injection regimens. This phase I study randomized 60 healthy adults to receive 300 mg tralokinumab, as two 1-mL subcutaneous injections, each delivered over 10 seconds, or one 2-mL injection delivered over 10 seconds (12 mL/min), 1 minute (2 mL/min), or 12 minutes (0.167 mL/min). No differences in the PK profile of tralokinumab were observed between cohorts. Immediately following injection, injection-site pain intensity (mean (SD)) was lowest following 0.167 mL/min injection (5.1 mm (8.0) via visual analog scale (VAS)) and greatest following 12 mL/min injection (41 mm (27.7) via VAS); with mean injection-site pruritus intensity low for all participants. Two types of local injection-site reactions were observed: erythema (58.3%) and hematoma/bleeding (18.3%). All treatment-emergent adverse events were mild. Tralokinumab 300 mg is well tolerated, with comparable PK, when administered by a single 2-mL injection at different rates of subcutaneous injection vs. two 1-mL injections.

    Engineering, administrative, and work practice controls have been recommended for many years to minimize exposure to nitrous oxide during dental procedures. To better understand the extent to which these exposure controls are used, the NIOSH Health and Safety Practices Survey of Healthcare Workers was conducted among members of professional practice organizations representing dentists, dental hygienists and dental assistants. The anonymous, modular, web-based survey was completed by 284 dental professionals in private practice who administered nitrous oxide to adult and/or pediatric patients in the seven days prior to the survey. Use of primary engineering controls [i.e., nasal scavenging mask and/or local exhaust ventilation (LEV) near the patient's mouth] was nearly universal, reported by 93% and 96% of respondents who administered to adult (A) and pediatric (P) patients, respectively. However, adherence to other recommended precautionary practices were lacking to varying degrees, and were essentially no different among those administering nitrous oxide to adult or pediatric patients. Examples of work practices which increase exposure risk, expressed as percent of respondents, included: not checking nitrous oxide equipment for leaks (41% A; 48% P); starting nitrous oxide gas flow before delivery mask or airway mask was applied to patient (13% A; 12% P); and not turning off nitrous oxide gas flow before turning off oxygen flow to the patient (8% A; 7% P). Absence of standard procedures to minimize worker exposure to nitrous oxide (13% of all respondents) and not being trained on safe handling and administration of nitrous oxide (3%) were examples of breaches of administrative controls which may also increase exposure risk. Successful management of nitrous oxide emissions should include properly fitted nasal scavenging masks, supplemental LEV (when nitrous oxide levels cannot be adequately controlled using nasal masks alone), adequate general ventilation, regular

    Scavenging systems and administrative and work practice controls for minimizing occupational exposure to waste anesthetic gases have been recommended for many years. Anesthetic gases and vapors that are released or leak out during medical procedures are considered waste anesthetic gases. To better understand the extent recommended practices are used, the NIOSH Health and Safety Practices Survey of Healthcare Workers was conducted in 2011 among members of professional practice organizations representing anesthesia care providers including physician anesthesiologists, nurse anesthetists, and anesthesiologist assistants. This national survey is the first to examine self-reported use of controls to minimize exposure to waste anesthetic gases among anesthesia care providers. The survey was completed by 1,783 nurse anesthetists, 1,104 physician anesthesiologists, and 100 anesthesiologist assistants who administered inhaled anesthetics in the seven days prior to the survey. Working in hospitals and outpatient surgical centers, respondents most often administered sevoflurane and, to a lesser extent desflurane and isoflurane, in combination with nitrous oxide. Use of scavenging systems was nearly universal, reported by 97% of respondents. However, adherence to other recommended practices was lacking to varying degrees and differed among those administering anesthetics to pediatric (P) or adult (A) patients. Examples of practices which increase exposure risk, expressed as percent of respondents, included: using high (fresh gas) flow anesthesia only (17% P, 6% A), starting anesthetic gas flow before delivery mask or airway mask was applied to patient (35% P; 14% A); not routinely checking anesthesia equipment for leaks (4% P, 5% A), and using a funnel-fill system to fill vaporizers (16%). Respondents also reported that facilities lacked safe handling procedures (19%) and hazard awareness training (18%). Adherence to precautionary work practices was generally highest among

    Lower radiopharmaceutical activities are used for myocardial perfusion scintigraphy (MPS) in the UK than in other countries. There is no evidence to suggest that higher activities improve imaging or clinical outcome. We undertook a multicentre study of the relationship between radiopharmaceutical activity and imaging outcome. Fifty-one patients with clinical referrals for MPS followed a 2-day protocol with an injection of 1,000 MBq {sup 99m}Tc-tetrofosmin for each of the stress and rest images. ECG-gated acquisition was performed in three rotations occupying 25, 35 and 40% of a standard acquisition, and rotations were summed to simulate administered activities of 250, 400, 750 and 1,000 MBq. Each set of images was reported by an experienced physician who was blinded to all clinical information and to the simulated activity. Scores were assigned for image quality, low count, attenuation and reconstruction artefact, segmental tracer uptake, segmental and global defect classification, and confidence in the global classification. The images were reported twice to assess intra-observer variability. Positive relationships were found between administered activity and overall image quality, observer confidence and intra-observer agreement of uptake score, and a negative relationship was found with low-count artefact. For the majority of comparisons, there was no additional improvement with increasing activity from 750 to 1,000 MBq. Intra-observer agreement was found to be better in female patients and in those below average body mass index. We conclude that higher administered radiopharmaceutical activities lead to better quality images and improved surrogate parameters for clinical outcome, but that activities above 750 MBq may be unnecessary in average patients.

    The estrogenic effect of orally administered bisphenol A (BPA) was investigated in a rainbow trout (Oncorhynchus mykiss) test system. Bisphenol A was administered orally to sexually immature rainbow trout every second day for up to 12 d in doses between 1.8 and 258 mg/kg every second day (/2d). Plasma vitellogenin was measured before and during the exposures, and the concentrations of BPA in plasma, liver, and muscle and the plasma concentrations of BPA glucuronic acid (BPAGA) were determined at the end of the experiments. Increases in average plasma vitellogenin levels were seen at oral exposure to 24 mg BPA/kg/2d; the most sensitive fish responded to 9.3 mg/kg/2d. At day 12, the 10, 50, and 90% effective doses for increase in vitellogenin synthesis were 13, 19, and 25 mg/kg/2d, respectively. Bisphenol A could be detected in liver, muscle, and plasma at the end of the exposure, generally in increasing concentrations with increasing doses; liver concentrations generally were higher than muscle concentrations. Four to five hours after the last feeding of doses between 3.6 and 24 mg BPA/kg, plasma BPA concentrations ranged between 400 and 1,200 nM, whereas BPAGA concentrations were between 2- and 10-fold higher. The difference between BPA and BPAGA concentrations increased with increasing BPA dose. Bisphenol A showed little tendency to bioaccumulate in rainbow trout; less than 1% of the total amount of BPA administered orally at doses between 1.8 and 258 mg/ kg/2d over the 10- or 12-d experimental period was retained in muscle and liver at 5 or 24 h after the end of the experiments.

    To assess the short-term efficacy of a video-based cognitive behavioral therapy for insomnia (CBT-I) as compared to a professionally administered CBT-I and to a no-treatment group. Randomized controlled trial. Radio-oncology department of a public hospital affiliated with Université Laval (CHU de Québec). Two hundred forty-two women with breast cancer who had received radiation therapy in the past 18 mo and who had insomnia symptoms or were using hypnotic medications were randomized to: (1) professionally administered CBT-I (PCBT-I; n = 81); (2) video-based CBT-I (VCBT-I; n = 80); and (3) no treatment (CTL; n = 81). PCBT-I composed of six weekly, individual sessions of approximately 50 min; VCBT-I composed of a 60-min animated video + six booklets. Insomnia Severity Index (ISI) total score and sleep parameters derived from a daily sleep diary and actigraphy, collected at pretreatment and posttreatment. PCBT-I and VCBT-I were associated with significantly greater sleep improvements, assessed subjectively, as compared to CTL. However, relative to VCBT-I, PCBT-I was associated with significantly greater improvements of insomnia severity, early morning awakenings, depression, fatigue, and dysfunctional beliefs about sleep. The remission rates of insomnia (ISI CBT-I) using a video format appears to be a valuable treatment option, but face-to-face sessions remain the optimal format for administering CBT-I efficaciously in patients with breast cancer. Self-help interventions for insomnia may constitute an appropriate entry level as part of a stepped care model. ClinicalTrials.gov Identifier: NCT00674830. Savard J, Ivers H, Savard MH, Morin CM.

    Purpose: The aim was to investigate whole-body and red marrow absorbed doses in treatments of neuroblastoma (NB) and adult neuroendocrine tumors (NETs) with {sup 131}I-metaiodobenzylguanidine and to propose a simple method for determining the activity to administer when dosimetric data for the individual patient are not available. Methods: Nine NB patients and six NET patients were included, giving in total 19 treatments as four patients were treated twice. Whole-body absorbed doses were determined from dose-rate measurements and planar gamma-camera imaging. For six NB and five NET treatments, red marrow absorbed doses were also determined using the blood-based method. Results: Dosimetric data from repeated administrations in the same patient were consistent. In groups of NB and NET patients, similar whole-body residence times were obtained, implying that whole-body absorbed dose per unit of administered activity could be reasonably well described as a power function of the patient mass. For NB, this functional form was found to be consistent with dosimetric data from previously published studies. The whole-body to red marrow absorbed dose ratio was similar among patients, with values of 1.4 ± 0.6–1.7 ± 0.7 (1 standard deviation) in NB treatments and between 1.5 ± 0.6 and 1.7 ± 0.7 (1 standard deviation) in NET treatments. Conclusions: The consistency of dosimetric results between administrations for the same patient supports prescription of the activity based on dosimetry performed in pretreatment studies, or during the first administration in a fractionated schedule. The expressions obtained for whole-body absorbed doses per unit of administered activity as a function of patient mass for NB and NET treatments are believed to be a useful tool to estimate the activity to administer at the stage when the individual patient biokinetics has not yet been measured.

    Full Text Available Abstract Background The objectives of this smoking cessation study among hospitalized smokers are to: 1 determine provider and patient receptivity, barriers, and facilitators to implementing the nurse-administered, inpatient Tobacco Tactics intervention versus usual care using face-to-face feedback and surveys; 2 compare the effectiveness of the nurse-administered, inpatient Tobacco Tactics intervention versus usual care across hospitals, units, and patient characteristics using thirty-day point prevalence abstinence at thirty days and six months (primary outcome post-recruitment; and 3 determine the cost-effectiveness of the nurse-administered, inpatient Tobacco Tactics intervention relative to usual care including cost per quitter, cost per life-year saved, and cost per quality-adjusted life-year saved. Methods/Design This effectiveness study will be a quasi-experimental design of six Michigan community hospitals of which three will get the nurse-administered Tobacco Tactics intervention and three will provide their usual care. In both the intervention and usual care sites, research assistants will collect data from patients on their smoking habits and related variables while in the hospital and at thirty days and six months post-recruitment. The intervention will be integrated into the experimental sites by a research nurse who will train Master Trainers at each intervention site. The Master Trainers, in turn, will teach the intervention to all staff nurses. Research nurses will also conduct formative evaluation with nurses to identify barriers and facilitators to dissemination. Descriptive statistics will be used to summarize the results of surveys administered to nurses, nurses’ participation rates, smokers’ receipt of specific cessation services, and satisfaction with services. General estimating equation analyses will be used to determine differences between intervention groups on satisfaction and quit rates, respectively, with

    Full Text Available Aim: To evaluate the effect of long-term use of silibinin, epigallocatechin (ECGC, quercetin and rutin on the absorption and tissue distribution of metformin and atenolol. Materials and Methods: Thirty male rats were used, allocated into 5 groups and treated as follow: 1st group treated with olive oil and served as control; the other 4 groups were treated with either silibinin, EPGC, quercetin or rutin, administered orally as oily solutions for 30 days. At day 30, a 300mg/kg metformin and 50mg/kg atenolol were administered orally; 3.0 hrs later, the animals were sacrificed and blood samples, tissues of brain, kidney and liver were obtained for evaluation of the drugs level. Results: The polyphenols increased both serum and tissue levels of metformin compared with controls. This effect was relatively varied according to the structural differences among flavonoids. Conclusion: Long-term use of supraphysiological doses of flavonoids increase absorption of Zn, Cu and Fe and their tissue availability in brain, kidney and liver; this effect seems to be different with variations in structural features.

    2002-12-01

    Full Text Available Introduction. There are increasing interests about pharmacotherapy in depressed children and adolescents. Althought TCAs (such as imipramine are approved for use in enuresis and ADHD, but controlled studies have failed to demonstrate efficacy of them over placebo in the treatment of depressive disorders in both children or adolescents. On the other hand, a relatively more amount of studies address SSRls (such as fluoxetine, as the drug of choice for treatment of depressed children and adolescents, because of theire effectiveness and safety.
    Methods. In this retrospective study, 306 depressed child and adolescent (7-18 year old who admitted to a psychiatric out patient clinic were studied (196 male and 110 female. Imipramine and fluoxetin were administered for 47 percent and 43 percent of cases, respectively.
    Results. In imipramin geoup and fluoxetine group the symptoms of 126 (87 percent and 102 (77 percent patient was improved, respectively. The frequency of side effects was 21 percent for imipramin (specialy sedation, dizziness and palpitation and 22 percent for fluoxatine (specially headache, insomnia and agitation.
    Discussion. This study suggests that both imipramin and fluoxetine are efficient for tratment of children and adolescents depression. However, because of high theraputic index of fluoxetine, this drug may be a better choice.

They then visited the clinic on 5 consecutive days, and, in a random order, performed 1 of the following: PEP, AD, PEP followed by AD (PEP-AD), AD followed by PEP (AD-PEP), and, no PT except for spontaneous coughing. Lung function was measured repeatedly before, during, and after PT; time needed for and sputum produced by each form of PT was recorded. PEP produced the highest amount of sputum, followed by PEP-AD, AD-PEP, and AD; all 4 forms of PT produced significantly more sputum than coughing. Lung function improved significantly after PEP, AD, and PEP-AD, but PEP-induced changes did not exceed those after AD. Within the investigated group, the PEP-induced lung function improvement per milliliter of sputum produced was significantly lower for those patients with airway hyperreactivity. The fact that the highest sputum yield with PEP was not reflected in higher PEP-effected lung function changes might thus be explained by PEP-induced bronchospasm in patients with airway hyperreactivity. PEP clears more sputum than AD or combined techniques; patients with airway hyperreactivity, however, should either prefer AD or should take a bronchodilator premedication before PEP.

    The aims of this study were to identify all available self-administered instruments measuring health literacy in people with diabetes and to determine the current instrument that is the most appropriate for applying to this population in both practice and research. A systematic review of measurement properties. MEDLINE, EMBASE and CINAHL electronic databases from their inception up to 28 March 2016. The methodological quality of each included study was assessed using the COnsensus-based Standards for the selection of health Measurement INstruments checklist. The reported results for measurement properties in the studies were assessed according to Terwee's quality criteria. Thirteen self-administered instruments measuring health literacy in people with diabetes were identified, of which six (44%) were diabetes-specific instruments. The instruments that covered the broadest contents of health literacy were the Health Literacy Scale and Health Literacy Questionnaire. The (test-retest) reliability, measurement error and responsiveness were not evaluated for any instrument, while internal consistency and hypothesis testing validity were the most frequently assessed measurement properties. With the current evidence, the Health Literacy Scale may be the most appropriate instrument for patients with diabetes in practice and research. However, the structural validity of this scale needs to be further established, particularly in other language versions. It is also recommended to use the Diabetes Numeracy Test-15 along with the Health Literacy Scale to complement the lack of numeracy measures in the Health Literacy Scale. © 2017 John Wiley & Sons Ltd.

    Astromicin (ASTM) was administered by intravenous drip infusion (i.v.d.) to 22 patients with chronic complicated urinary tract infections and the clinical efficacy and safety of this drug were evaluated. The overall clinical efficacy rate obtained was 71.4% (excellent 6; moderate 9) of 21 evaluable cases by the UTI committee's criteria. Concerning the response on clinical isolates, the drug was highly effective especially against strains of Escherichia coli, indole positive Proteus and Serratia marcescens. It was not effective, however, against 2 strains of Pseudomonas aeruginosa. As for adverse reactions, there was one case which complained of headache on the 3rd day after starting treatment. In this case the drug administration was discontinued at the 5th day. The symptom disappeared within 24 hours without any treatment. No any other adverse reactions were noted. With regard to clinical test values for peripheral blood, liver and renal functions, no abnormality was observed in any of the cases treated with the drug. In conclusion, ASTM was found to be a highly effective and safe drug when administered by intravenous drip infusion in the treatment of chronic complicated urinary tract infections.

    Full Text Available Objectives: Higher rate of slime production has been found in pathogen bacteria strains. Accordingly, the factors thatcontribute to higher slime production rate increase the infection risk, while the factors that reduce the slime productionrate will reduce the infection risk. The effect of some drugs that are administered through catheters in intensive careunits on slime production with coagulase negative Staphylococci was investigated.Materials and methods: In this study, the effect of four different preparations containing Glyceryl trinitrate (Perlinganit®, Dexmedetomidine (Precedex®, Esmolol (Brevibloc®, and Propofol (Propofol® on slime production of 24Staphylococcus epidermidis strains isolated from blood cultures of patients, and reference strain were investigated. Slimeproduction was determined using ‘the quantitative microdilution plaque test’ described by Christensen.Results: Under controlled medium, eight strains formed slimes, and in the media containing esmolol, glyceryl trinitrate,dexmedetomidine, and propofol slimes were positive for five, 21, 15, and 18 strains, respectively. The rate of slime productionin glyceryl trinitrate, dexmedetomidine, and propofol containing media were higher than that of the controls.Conclusions: In the light of the results of this study, it is concluded that the drugs and/or additives increase the rate ofslime production. The effects of the preparations administered through catheters on slime production should be investigated,and these effects should be kept in mind during their use.

    The administration of radionuclide therapies presents significant radiation protection challenges. The aim of this work was to develop a delivery system for intravenous radioisotope therapies to substantially moderate radiation exposures to staff and operators. A novel device (InfuShield) was designed and tested before being used clinically. The device consists of a shielded enclosure which contains the therapeutic activity and, through the hydraulic action of back-to-back syringes, allows the activity to be administered using a syringe pump external to the enclosure. This enables full access to the pump controls while simultaneously reducing dose to the operator. The system is suitable for use with all commercially available syringe pumps and does not require specific consumables, maximising both the flexibility and economy of the system. Dose rate measurements showed that at key stages in an I mIBG treatment procedure, InfuShield can reduce dose to operators by several orders of magnitude. Tests using typical syringes and infusion speeds show no significant alteration in administered flow rates (maximum of 1.2%). The InfuShield system provides a simple, safe and low cost method of radioisotope administration.

    Complex and lengthy endoscopic examinations like endoscopic ultrasonography and/or endoscopic retrograde cholangiopancreatography benefit from deep sedation, due to an enhanced quality of examinations, reduced discomfort and anxiety of patients, as well as increased satisfaction for both the patients and medical personnel. Current guidelines support the use of propofol sedation, which has the same rate of adverse effects as traditional sedation with benzodiazepines and/or opioids, but decreases the procedural and recovery time. Non-anesthesiologist administered propofol sedation has become an option in most of the countries, due to limited anesthesiology resources and the increasing evidence from prospective studies and meta-analyses that the procedure is safe with a similar rate of adverse events with traditional sedation. The advantages include a high quality of endoscopic examination, improved satisfaction for patients and doctors, as well as decreased recovery and discharge time. Despite the advantages of non-anesthesiologist administered propofol, there is still a continuous debate related to the successful generalization of the procedures.

    The aim of this study was to determine the optimum administered activity to patients, of the DMSA-Tc-99m looking for good image quality in gamma camera and a best radiological protection for the patient. Three protocols and two activity values in each protocol were tested (71.2 MBq and 132.8 MBq) in six patients each. An observer blinded to the administered activity, graded the rear view of both kidneys in the 36 patients. The relation of the Rois in kidney/bladder and kidney/liver, and the labeling yield were the most important parameters in the construction of a discriminatory function of image quality (r=0.56, r=0.33 and r=0.461 respectively). The correlation between the observer's opinion and the prediction of the function was r=0.429. The function classified 91.7% of the cases correctly. The best results for the patient's radiological protection were obtained by using 71.2 MBq and 700 k Counts as stopped criterion. When the labeling yield was lower than 98% it was better to applied 132.8 MBq and to stop the scanning after 3 minutes to guarantee a best image quality. (author)

    Experiments were performed to investigate the effect of ascorbic acid (AA) in reducing hemato-biochemical changes in pack donkeys during the cold-dry (harmattan) season. Six experimental donkeys administered orally AA (200 mg/kg) and six control donkeys not administered ascorbic acid were subjected to packing. Blood samples were collected from all donkeys for hematological and biochemical analyses. In the control donkeys, packed cell volume (PCV), erythrocyte count and hemoglobin concentration (Hb) decreased significantly (Ppacking. In the experimental donkeys, there was no significant difference between the pre- and post-packing values of PCV, erythrocyte count and Hb. In the control donkeys, the neutrophil and neutrophil:lymphocyte ratio increased significantly (Ppacking, but in the experimental donkeys, the pre- and post-packing values were not significantly different. The eosinophil count increased significantly (Ppacking. In conclusion, packing exerted significant adverse effects on the hematological parameters ameliorated by AA administration. AA may modulate neutrophilia and induce a considerable alteration of erythroid markers in donkeys subjected to packing during the harmattan season.

  20. Pharmacokinetics of the Antiviral Lectin Griffithsin Administered by Different Routes Indicates Multiple Potential Uses

    Full Text Available Griffithsin (GRFT is a red alga-derived lectin with demonstrated broad spectrum antiviral activity against enveloped viruses, including severe acute respiratory syndrome–Coronavirus (SARS-CoV, Japanese encephalitis virus (JEV, hepatitis C virus (HCV, and herpes simplex virus-2 (HSV-2. However, its pharmacokinetic profile remains largely undefined. Here, Sprague Dawley rats were administered a single dose of GRFT at 10 or 20 mg/kg by intravenous, oral, and subcutaneous routes, respectively, and serum GRFT levels were measured at select time points. In addition, the potential for systemic accumulation after oral dosing was assessed in rats after 10 daily treatments with GRFT (20 or 40 mg/kg. We found that parenterally-administered GRFT in rats displayed a complex elimination profile, which varied according to administration routes. However, GRFT was not orally bioavailable, even after chronic treatment. Nonetheless, active GRFT capable of neutralizing HIV-Env pseudoviruses was detected in rat fecal extracts after chronic oral dosing. These findings support further evaluation of GRFT for pre-exposure prophylaxis against emerging epidemics for which specific therapeutics are not available, including systemic and enteric infections caused by susceptible enveloped viruses. In addition, GRFT should be considered for antiviral therapy and the prevention of rectal transmission of HIV-1 and other susceptible viruses.

  1. Effect of Orally Administered Glutathione-Montmorillonite Hybrid Systems on Tissue Distribution

    Full Text Available An ubiquitous tripeptide, glutathione (GSH, is assigned a role in detoxification, activation of immune system, intermediary metabolism, transport, and protection of cells against free radicals or reactive oxygen species. However, instability of orally administered GSH in gastrointestinal (GI tract leads to low absorption and low bioavailability in tissues. In this study, we attempted to synthesize GSH-montmorillonite (MMT hybrid systems by intercalating GSH into the interlayers of a cationic clay delivery carrier, MMT, to improve GSH bioavailability at the systemic level. Polymer coating of the hybrid with polyvinylacetal diethylaminoacetate (AEA was further performed to obtain better stability. Synthetic condition of both GSH-MMT and AEA-GSH-MMT hybrids was optimized, and then GSH-delivery efficiency was evaluated in various organs after oral administration in normal as well as GSH-deficient mice. The present GSH-MMT hybrids remarkably enhanced GSH concentration in the plasma, heart, kidney, and liver, especially when AEA-GSH-MMT hybrid was administered under GSH-deficient condition. Moreover, both hybrids did not induce acute oral toxicity up to 2000 mg/kg, suggesting their great potential for pharmaceutical application.

  2. The problem of bias when nursing facility staff administer customer satisfaction surveys.

    2002-10-01

    Customer satisfaction instruments are being used with increasing frequency to assess and monitor residents' assessments of quality of care in nursing facilities. There is no standard protocol, however, for how or by whom the instruments should be administered when anonymous, written responses are not feasible. Researchers often use outside interviewers to assess satisfaction, but cost considerations may limit the extent to which facilities are able to hire outside interviewers on a regular basis. This study was designed to investigate the existence and extent of any bias caused by staff administering customer satisfaction surveys. Customer satisfaction data were collected in 1998 from 265 residents in 21 nursing facilities in North Dakota. Half the residents in each facility were interviewed by staff members and the other half by outside consultants; scores were compared by interviewer type. In addition to a tabulation of raw scores, ordinary least-squares analysis with facility fixed effects was used to control for resident characteristics and unmeasured facility-level factors that could influence scores. Significant positive bias was found when staff members interviewed residents. The bias was not limited to questions directly affecting staff responsibilities but applied across all types of issues. The bias was robust under varying constructions of satisfaction and dissatisfaction. A uniform method of survey administration appears to be important if satisfaction data are to be used to compare facilities. Bias is an important factor that should be considered and weighed against the costs of obtaining outside interviewers when assessing customer satisfaction among long term care residents.

    We studied absorption, distribution, metabolism, and excretion of polyamines (putrescine, spermidine, and spermine) in the gastrointestinal tract using {sup 15}N-labeled polyamines as tracers and ionspray ionization mass spectrometry (IS-MS). The relatively simple protocol using rats bearing solid tumors provided useful information. Three {sup 15}N-labeled polyamines that were simultaneously administered were absorbed equally from gastrointestinal tract, and distributed within tissues at various concentrations. The uptake of {sup 15}N-spermidine seemed preferential to that of {sup 15}N-spermine since the concentrations of {sup 15}N-spermidine in the liver and tumors were higher, whereas those of {sup 15}N-spermine were higher in the kidney, probably due to the excretion of excess extracellular spermine. Most of the absorbed {sup 15}N-putrescine seemed to be lost, suggesting blood and tissue diamine oxidase degradation. Concentrations of {sup 15}N-spermidine and {sup 15}N-spermine in the tumor were low. We also describe the findings from two rats that were administered with {sup 15}N-spermine. The tissue concentrations of {sup 15}N-spermine were unusually high, and significant levels of {sup 15}N-spermidine were derived from {sup 15}N-spermine in these animals. (author)

    Full Text Available Abstract Background Self report of smoking status is potentially unreliable in certain situations and in high-risk populations. This study aimed to determine the accuracy and acceptability of computer administered self-report of smoking status among a low socioeconomic (SES population. Methods Clients attending a community service organisation for welfare support were invited to complete a cross-sectional touch screen computer health survey. Following survey completion, participants were invited to provide a breath sample to measure exposure to tobacco smoke in expired air. Sensitivity, specificity, positive predictive value and negative predictive value were calculated. Results Three hundred and eighty three participants completed the health survey, and 330 (86% provided a breath sample. Of participants included in the validation analysis, 59% reported being a daily or occasional smoker. Sensitivity was 94.4% and specificity 92.8%. The positive and negative predictive values were 94.9% and 92.0% respectively. The majority of participants reported that the touch screen survey was both enjoyable (79% and easy (88% to complete. Conclusions Computer administered self report is both acceptable and accurate as a method of assessing smoking status among low SES smokers in a community setting. Routine collection of health information using touch-screen computer has the potential to identify smokers and increase provision of support and referral in the community setting.

    This study determined human skeletal muscle oxygenation dynamics during and after a single bout of self-administered stretching (SAS) of the plantar flexors. Nine healthy recreationally fit men (n = 7; age = 25·7 years) and women (n = 2; age = 23·5 years) performed two protocols: (i) one bout of SAS for 4 min and (ii) one bout of moderate intensity cycling for 4 min. We used near infrared spectroscopy to measure changes in muscle deoxygenated haemoglobin-myoglobin ([HHb]) and blood volume ([Hbtot ]) of gastrocnemius medialis muscle before, during and after stretching. The SAS caused an increase (Pstretching between 60 and 240 s relative to baseline, but not at 30 s. No significant difference was found for [Hbtot ] at any time interval during SAS. Furthermore, the increase in local blood flow (suggested by [Hbtot ] changes) was found to be significantly increased relative to baseline at 1, 5 and 10 min after SAS, thus providing novel evidence for a poststretch hyperaemia. No significant interaction for [HHb] was found between stretching and cycling conditions, suggesting that the metabolic disturbance during stretching closely resembles moderate intensity exercise. These findings suggest that a single self-administered stretch for 60 s can produce a substantial microcirculatory event and that blood flow may be enhanced for up to 10 min after stretching.

    2011-03-01

    Human and mouse urocortin 3 (Ucn3) were first identified in 2001. Ucn3 binds selectively to corticotropin-releasing factor receptor type 2 (CRF-R2). Previous studies have shown that centrally administered Ucn3 decreases food intake in rats. However, the role of Ucn3 in the regulation of gut motility remains to be determined. In the present study, we investigated the effects of peripherally administered Ucn3 on food intake and gastric emptying in mice. After intraperitoneal (i.p.) administration of Ucn3, food intake was measured in the light and dark phases, and the rate of gastric emptying was determined. We found that i.p. administration of Ucn3 significantly inhibited feeding behavior in mice, and significantly delayed gastric emptying 1-2 h after administration in a dose-dependent manner. These results suggest that Ucn3 contributes to the modulation of feeding behavior and gut motility. Thus, Ucn3 and CRF-R2 may be involved in the pathogenesis of functional gastrointestinal and eating disorders.

    Purpose: The reproductive toxicology of mangafodipir trisodium (MnDPDP, Tesla-scan), a new hepatobiliary MR contrast agent, was evaluated in rats and rabbits. Material and Methods: Male and female fertility and post-natal development were examined in rats after repeated i.e. injections of MnDPDP. The developmental toxicity in rats was investigated after repeated daily i.v. injections during organogenesis with MnDPDP, MnCl{sub 2}, or DPDP, as well as with MnCl{sub 2} administered orally. The developmental toxicity of i.v. injected MnDPDP was also investigated in rabbits. Results: MnDPDP (100 {mu}mol/kg) had no adverse effects on rat fertility. However, both MnDPDP (10-40 {mu}mol/kg) and MnCl{sub 2} (30 {mu}mol/kg) caused skeletal abnormalities in the rat, but not in the rabbit given 20 {mu}mol MnDPDP/kg. Maternal treatment of rats with MnDPDP (40 {mu}mol/kg) reduced survival and body weights of neonates, and adversely affected their functional, but not physical development. No skeletal abnormalities were seen in the rat after i.v. administered DPDP (40 {mu}mol/kg) or MnCl{sub 2} (6 {mu}mol/kg), or after MnCl{sub 2} (400 {mu}mol/kg) given by oral gavage. Maternal toxicity was not seen in rats or rabbits given these doses. (orig./AJ).

    Combination therapies with fibrates and statins are used to treat cardiovascular diseases, because of their synergistic effect on lowering plasma lipids. However, fatal side-effects like rhabdomyolysis followed by acute renal necrosis sometimes occur. To elucidate biochemical changes resulting from the interaction of fibrates and statins, doses of 100 mg/kg fenofibrate, 50mg/kg clofibrate, 70 mg/kg atorvastatin and 200 mg/kg pravastatin as well as combinations thereof were administered to Crl:Wi(Han) rats for 4 weeks. Plasma metabolome profile was measured on study days 7, 14 and 28. Upon study termination, clinical pathology parameters were measured. In a separate experiment plasmakinetic data were measured in male rats after 1 week of drug administration in monotherapy as well as in combinations. Lowering of blood lipid levels as well as toxicological effects, like liver cell degradation (statins) and anemia (fibrates) and distinct blood metabolite level alterations were observed in monotherapy. When fibrates and statins were co-administered metabolite profile interactions were generally underadditive or at the utmost additive according to the linear mixed effect model. However, more metabolite levels were significantly altered during combination therapy. New effects on the antioxidant status and the cardiovascular system were found which may be related to a development of rhabdomyolysis. Accumulation of drugs during the combination therapy was not observed.

  9. Orally administered misoprostol for induction of labor with prelabor rupture of membranes at term.

    Radoff, Kari A

    2014-01-01

    Prelabor rupture of membranes (PROM) occurs in approximately 8% to 10% of women with term pregnancies. The management of PROM continues to be controversial. Approaches include expectant management and immediate induction of labor. The use of orally administered misoprostol for the management of women with PROM may provide significant advantages when they choose immediate induction of labor. This literature review presents current evidence that supports the use of oral misoprostol for women with PROM, including the benefits of a decreased interval time from PROM to vaginal birth, good safety profile, and reductions in the use of oxytocin augmentation and epidural anesthesia. In addition to clinically proven benefits to women of oral misoprostol for PROM, it also has the potential to reduce chorioamnionitis by reducing the number of sterile vaginal examinations performed thereby reducing the risk of ascending bacteria. Women have also reported acceptability and satisfaction when using oral misoprostol for immediate induction of labor. This review of literature discusses what is known about the use of orally administered misoprostol for the management of term PROM and makes recommendations for clinical use.

    This paper describes development of a prototype data analytics portal for analysis of accumulated screening results from eCHAT (electronic Case-finding and Help Assessment Tool). eCHAT allows individuals to conduct a self-administered lifestyle and mental health screening assessment, with usage to date chiefly in the context of primary care waiting rooms. The intention is for wide roll-out to primary care clinics, including secondary school based clinics, resulting in the accumulation of population-level data. Data from a field trial of eCHAT with sexual health questions tailored to youth were used to support design of a data analytics portal for population-level data. The design process included user personas and scenarios, screen prototyping and a simulator for generating large-scale data sets. The prototype demonstrates the promise of wide-scale self-administered screening data to support a range of users including practice managers, clinical directors and health policy analysts.

    Full Text Available This is an introduction to finite simple groups, in particular sporadic groups, intended for physicists. After a short review of group theory, we enumerate the 1+1+16=18 families of finite simple groups, as an introduction to the sporadic groups. These are described next, in three levels of increasing complexity, plus the six isolated ''pariah'' groups. The (old five Mathieu groups make up the first, smallest order level. The seven groups related to the Leech lattice, including the three Conway groups, constitute the second level. The third and highest level contains the Monster group M, plus seven other related groups. Next a brief mention is made of the remaining six pariah groups, thus completing the 5+7+8+6=26 sporadic groups. The review ends up with a brief discussion of a few of physical applications of finite groups in physics, including a couple of recent examples which use sporadic groups.

    The purpose of this study is to identify a method for optimising the administered activity and acquisition time for (18)F-FDG PET imaging, yielding images of consistent quality for patients with varying body sizes and compositions, while limiting radiation doses to patients and staff. Patients referred for FDG scans had bioimpedance measurements. They were injected with 3 MBq/kg of (18)F up to 370 MBq and scanned on a Siemens Biograph mCT at 3 or 4 min per bed position. Data were rebinned to simulate 2- and 1-min acquisitions. Subjective assessments of image quality made by an experienced physician were compared with objective measurements based on signal-to-noise ratio and noise equivalent counts (NEC). A target objective measure of image quality was identified. The activity and acquisition time required to achieve this were calculated for each subject. Multiple regression analysis was used to identify expressions for the activity and acquisition time required in terms of easily measurable patient characteristics. One hundred and eleven patients were recruited, and subjective and objective assessments of image quality were compared for 321 full and reduced time scans. NEC-per-metre was identified as the objective measure which best correlated with the subjective assessment (Spearman rank correlation coefficient 0.77) and the best discriminator for images with a subjective assessment of "definitely adequate" (area under the ROC curve 0.94). A target of 37 Mcount/m was identified. Expressions were identified in terms of patient sex, height and weight for the activity and acquisition time required to achieve this target. Including measurements of body composition in these expressions was not useful. Using these expressions would reduce the mean activity administered to this patient group by 66 MBq compared to the current protocol. Expressions have been identified for the activity and acquisition times required to achieve consistent image quality in FDG imaging

    Full Text Available The author studies the $bf R$$G$-module $A$ such that $bf R$ is an associative ring, a group $G$ has infinite section $p$-rank (or infinite 0-rank, $C_{G}(A=1$, and for every proper subgroup $H$ of infinite section $p$-rank (or infinite 0-rank respectively the quotient module $A/C_{A}(H$ is a finite $bf R$-module. It is proved that if the group $G$ under consideration is locally soluble then $G$ is a soluble group and $A/C_{A}(G$ is a finite $bf R$-module.

    Background and study aims: Endoscopist-Directed Nurse-Administered Propofol Sedation (EDNAPS) has been evaluated in community settings rather than tertiary referral centers. Patients and methods: A hospital-wide prospectively collected database of Medical Emergency Team Calls (METCALL), emergency responses triggered by medically unstable patients, was reviewed. Responses that followed EDNAPS were extracted and compared with a prospectively entered database of all endoscopies performed using EDNAPS over the same period. Results: A total of 33,539 endoscopic procedures (16,393 gastroscopies, 17,146 colonoscopies) were performed on 27,989 patients using EDNAPS. Intravenous drugs included midazolam (0 – 5 mg), fentanyl (0 – 100 mcg), and propofol (10 – 420 mg). Of 23 METCALLs (18 gastroscopies and 5 colonoscopies), there were 16 with ASA scores of III or higher. Indications for gastroscopy were gastrointestinal (GI) hemorrhage (n = 11; 8 variceal, 3 nonvariceal), dysphagia (n = 5), PEG removal (n = 1), and dyspepsia (n = 1). Fifteen of 22 patients, including all of those who had a colonoscopy, made a full recovery and returned to the ward or were discharged home. In the gastroscopy group, seven were intubated and admitted to Intensive Care, of whom six were emergency cases for gastrointestinal bleeding (n = 4 variceal, n = 2 non variceal) and one in which the indication was PEG removal. Two deaths occurred in the intubated group. Conclusions: In a tertiary referral center, EDNAPS for low-to-moderate risk (ASA ≤ 2) patients undergoing gastroscopy and colonoscopy is very safe. Gastroscopy is associated with greater anesthetic risk than colonoscopy and those with high ASA scores needing urgent endoscopy for upper gastrointestinal hemorrhage are at particular risk of cardiorespiratory decompensation.

    Co-administration of artemether-lumefantrine with milk is recommended to improve lumefantrine (L) absorption but milk may not be available in resource-limited settings. This study explored the effects of cheap local food in Uganda on oral bioavailability of lumefantrine relative to milk. In an open-label, four-period crossover study, 13 healthy adult volunteers were randomized to receive a single oral dose of artemether-lumefantrine (80 mg artemether/480 mg lumefantrine) with water, milk, maize porridge or maize porridge with oil on separate occasions. Plasma lumefantrine was assayed using high-performance liquid chromatography with ultraviolet detection. Pharmacokinetic exposure parameters were determined by non-compartmental methods using WinNonlin. Peak concentrations (Cmax ) and area under concentration-time curve restricted to 48 hr after single dosing (AUC(0-48) ) were selected for relative bioavailability evaluations using confidence interval approach for average bioequivalence. Lumefantrine exposure was comparable in milk and maize porridge plus oil study groups. When artemether-lumefantrine was administered with maize porridge plus oil, average bioequivalence ranges (means ratios 90% CI, 0.84-1.88 and 0.85-1.69 for Cmax and AUC(0-48) , respectively) were within and exceeded acceptance ranges relative to milk (90% CI, 0.80-1.25). Both fasted and maize porridge groups demonstrated similarly much lower ranges of lumefantrine exposures (bioinequivalence) relative to milk. If milk is not available, it is thus possible to recommend fortification of carbohydrate-rich food with little fat (maize porridge plus vegetable oil) to achieve similarly optimal absorption of lumefantrine after artemether-lumefantrine administration.

    Proper training to improve safety of NAPS (nurse-administered propofol sedation) is essential. To communicate our experience with a training program of NAPS. In 2007, a training program was introduced for endoscopists and endoscopy nurses in collaboration with the Department of Anaesthesiology. During a 2.5-year period, eight nurses were trained. Propofol was given as monotherapy. The training program for nurses consisted of a 6-week course including theoretical and practical training whereas the training program for endoscopists consisted of 2.5 h of theory. Patients were selected based on strict criteria including patients in ASA (American Society of Anesthesiologists) group I-III. 2527 patients undergoing 2.656 gastrointestinal endoscopic procedures were included. The patients were ASA group I, II and III in 34.7%, 56% and 9,3%, respectively. Median dose of propofol was 300 mg. No mortality was noted. 119 of 2527 patients developed short lasting hypoxia (4.7%); 61 (2.4%) needed suction; 22 (0.9%) required bag-mask ventilation and 8 (0.3%) procedures had to be discontinued. In 11 patients (0.4%), anesthetic assistance was called due to short lasting desaturation. 34 patients (1.3%) experienced a change in blood pressure greater than 30%. NAPS provided by properly trained nurses according to the present protocol is safe and only associated with a minor risk (short lasting hypoxia 4.7%). National or international structured training programs are at present few or non-existing. The present training program has documented its value and is suggested as the basis for the current development of guidelines.

    Full Text Available Background: Both magnesium and clonidine are known to inhibit catecholamine and vasopressin release and attenuate hemodynamic response to pneumoperitoneum. This randomized, double blinded, placebo controlled study has been designed to assess which agent attenuates hemodynamic stress response to pneumoperitoneum better. Materials and Methods: 120 patients undergoing elective laparoscopic cholecystectomy were randomized into 4 groups of 30 each. Group K patients received 50 ml normal saline over a period of 15 min after induction and before pneumoperitoneum, group M patients received 50 mg/kg of magnesium sulfate in normal saline (total volume 50 ml over same time duration. Similarly group C1 patients received 1 μg/kg clonidine and group C2 1.5 μg/kg clonidine respectively in normal saline (total volume 50 ml. Blood pressure and heart rate were recorded before induction (baseline value, at the end of infusions and every 5 min after pneumoperitoneum. Statistical Analysis: Paired t test was used for intra-group comparison and ANOVA for inter-group comparison. Results: Systolic blood pressure was significantly higher in control group as compared to all other groups during pneumoperitoneum. On comparing patients in group M and group C1, no significant difference in systolic BP was found at any time interval. Patients in group C2 showed best control of systolic BP. As compared to group M and group C1, BP was significantly lower at 10, 30 and 40 min post pneumoperitoneum. No significant episodes of hypotension were found in any of the groups. Extubation time and time to response to verbal command like eye opening was significantly longer in group M as compared to other groups. Conclusion: Administration of magnesium sulfate or clonidine attenuates hemodynamic response to pneumoperitoneum. Although magnesium sulfate 50 mg/kg produces hemodynamic stability comparable to clonidine 1 μg/kg, clonidine in doses of 1.5μg/kg blunts the hemodynamic response

    BACKGROUND: Infliximab is usually administered by two monthly intravenous (iv) infusions, therefore requiring visits to hospital. Adalimumab is administered by self subcutaneous (sc) injections every other week. Both of these anti-TNF drugs appear to be equally efficacious in the treatment of Crohn\\'s Disease and therefore the decision regarding which drug to choose will depend to some extent on patient choice, which may be based on the mode of administration.The aims of this study were to compare preferences in Inflammatory Bowel Disease (IBD) patients for two currently available anti-TNF agents and the reasons for their choices. METHODS: An anonymous questionnaire was distributed to IBD patients who had attended the Gastroenterology service (Ulster Hospital, Dundonald, Belfast, N. Ireland. UK) between January 2007 and December 2007. The patients were asked in a hypothetical situation if the following administering methods of anti-TNF drugs (intravenous or subcutaneous) were available, which drug route of administration would they choose. RESULTS: One hundred and twenty-five patients fulfilled the inclusion criteria and were issued questionnaires, of these 78 questionnaires were returned (62 percent response). The mean age of respondent was 44 years. Of the total number of respondents, 33 patients (42 percent) preferred infliximab and 19 patients (24 percent) preferred adalimumab (p = 0.07). Twenty-six patients (33 percent) did not indicate a preference for either biological therapy and were not included in the final analysis. The commonest reason cited for those who chose infliximab (iv) was: "I do not like the idea of self-injecting," (67 percent). For those patients who preferred adalimumab (sc) the commonest reason cited was: "I prefer the convenience of injecting at home," (79 percent). Of those patients who had previously been treated with an anti-TNF therapy (n = 10, all infliximab) six patients stated that they would prefer infliximab if given the choice
