    Recent clinical trials with chimeric antigen receptor (CAR) redirected T cells targeting CD19 revealed particular efficacy in the treatment of leukemia/lymphoma, however, were accompanied by a lasting depletion of healthy B cells. We here explored CD30 as an alternative target, which is validated in lymphoma therapy and expressed by a broad variety of Hodgkin's and non-Hodgkin's lymphomas. As a safty concern, however, CD30 is also expressed by lymphocytes and hematopoietic stem and progenitor cells (HSPCs) during activation. We revealed that HRS3scFv-derived CAR T cells are superior since they were not blocked by soluble CD30 and did not attack CD30+ HSPCs while eliminating CD30+ lymphoma cells. Consequently, normal hemato- and lymphopoiesis was not affected in the long-term in the humanized mouse; the number of blood B and T cells remained unchanged. We provide evidence that the CD30+ HSPCs are protected against a CAR T-cell attack by substantially lower CD30 levels than lymphoma cells and higher levels of the granzyme B inactivating SP6/PI9 serine protease, which furthermore increased upon activation. Taken together, adoptive cell therapy with anti-CD30 CAR T cells displays a superior therapeutic index in the treatment of CD30+ malignancies leaving healthy activated lymphocytes and HSPCs unaffected.

    Narrow therapeutic index drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures and/or adverse drug reactions that are life-threatening or result in persistent or significant disability or incapacity. The US Food and Drug Administration proposes that the bioequivalence of narrow therapeutic index drugs be determined using a scaling approach with a four-way, fully replicated, crossover design study in healthy subjects that permits the simultaneous equivalence comparison of the mean and within-subject variability of the test and reference products. The proposed bioequivalence limits for narrow therapeutic index drugs of 90.00%-111.11% would be scaled based on the within-subject variability of the reference product. The proposed study design and data analysis should provide greater assurance of therapeutic equivalence of narrow therapeutic index drug products.

    The increase/modification of the Cisplatinum therapeutic index by neoplastic tissue exposure to optical radiation emitted between 400-2000 nm was studied; Cisplatinumum molecules do not absorb between 400 nm-2 □m. Doppler ultrasonography indicates that, following exposure, the living tissue local micro-vascularisation increases in a controlled and reversible way. The increase in the Cisplatinum therapeutic index may be produced by accelerating the intracellular hydrolyze processes due to the water molecules absorption in the near infrared. The irradiation makes possible the use of Cisplatinumum doses 10 times lower than in conventional chemotherapy; this generates lower secondary effects (kidney toxicity) while increasing the drug antineoplastic effect.

    Study Design Controlled laboratory study, repeated-measures design. Background Previous studies have reported that the superior and inferior portions of the gluteus maximus have different functional roles. Knowledge of how the different portions of the gluteus maximus are activated during therapeutic exercise may lead to more specific exercise prescription. Objective To compare muscle activation of the superior and inferior portions of the gluteus maximus during commonly used therapeutic exercises. Methods Twenty healthy persons participated. Electromyographic (EMG) signals were obtained from the superior and inferior portions of the gluteus maximus using fine-wire electrodes. Normalized EMG signal amplitudes were compared between the superior and inferior gluteus maximus across 11 exercises using a 2-way repeated-measures analysis of variance. Results The superior portion of the gluteus maximus had significantly greater relative EMG activity than the inferior portion of the gluteus maximus during exercises that incorporated elements of hip abduction and/or external rotation (5 of 11 exercises evaluated). There was no significant difference in activation between the superior and inferior portions of the gluteus maximus during the remaining 6 exercises. Conclusion The results of the present study demonstrate preferential activation of the superior portion of the gluteus maximus during exercises that incorporate elements of hip abduction and/or external rotation. In contrast, exercises that primarily involve hip extension target both portions of the gluteus maximus to a similar extent. J Orthop Sports Phys Ther 2016;46(9):794-799.

    The disproportionate surgical indication in patients with diabetic foot, as well as the large number of major amputations of the pelvic limb have created the necessity of conceiving a therapeutic-prognostic index to guide the physician in establishing the adequate surgical indication. The aim of this analysis is to extend a former research published in 2014, regarding the new prognostic-therapeutic index used in the diabetic foot pathology, that included 929 patients. We have analyzed a number of 1221 patients, that were admitted at the Surgery Clinic of the Cantacuzino Hospital, between January 2013 and June 2015, suffering from diabetes mellitus and associating diabetic foot lesions. The new therapeutic-prognostic index has been calculated for the retrospective lot, resulting into a concordance between the actual surgical intervention and the prognostic index of 79.4%; for the patients evaluated prospectively we have found a confirmation of the relation between the performed surgical intervention and the forecasted surgical intervention, of 86,8%. The new therapeutic-prognostic index is of a major usefulness in recommending an adequate therapeutic conduct correlated to the severity of the lesion, especially in facilities where the pathology of the diabetic foot is less known.

    Full Text Available Abstract Background One of the rare presentations of superior vena cava syndrome is bleeding of "downhill" esophageal varices (DEV and different approaches have been used to control it. This is a case report whose DEV was eradicated by band ligation for the first time. Case presentation We report a 42-year-old man who is a known case of Behcet's disease. The patient's first presentation was superior vena cava syndrome due to thrombosis followed by bipolar ulcers and arthralgia. He received warfarin, prednisolone and azathioprine. The clinical course of the patient was complicated by one episode of hematemesis without abdominal pain when the patient's PT was in therapeutic range. After resuscitation and correction of PT with fresh frozen plasma transfusion, upper gastrointestinal endoscopy was done. Prominent varices were seen in the upper third of the esophagus, tapering to the middle part without acute bleeding. Stomach and duodenum were normal. Color ultrasonography evaluation of the portal, hepatic and splenic veins was negative for thrombosis. Band ligation was done and the patient's bleeding did not recur. Conclusion Band ligation is a safe and effective method for controlling DEV bleeding in patients with uncorrectable underlying disorders.

    We have previously shown that a novel microtubule-modulating noscapinoid, EM011 (9-Br-Nos), displays potent anticancer activity by inhibition of cellular proliferation and induction of apoptosis in prostate cancer cells and preclinical mice models. However, physicochemical and cellular barriers encumber the development of viable formulations for future clinical translation. To circumvent these limitations, we have synthesized EM011-cyclodextrin inclusion complexes to improve solubility and enhance therapeutic index of EM011. Phase solubility analysis indicated that EM011 formed a 1:1 stoichiometric complex with β-CD and methyl-β-CD, with a stability constant (K(c)) of 2.42 × 10(-3) M and 4.85 × 10(-3) M, respectively. Fourier transform infrared spectroscopy suggested the penetrance of either a O-CH(2) or OCH(3)-C(6)H(4)-OCH(3) moiety of EM011 in the β-CD or methyl-β-CD cavity. In addition, multifarious techniques, namely, differential scanning calorimetry, powder X-ray diffraction, scanning electron microscopy, NMR spectroscopy, and computational studies validated the cage complex of EM011 with β-CD and methyl-β-CD. Moreover, rotating frame overhauser enhancement spectroscopy showed that the H(a) proton of the OCH(3)-C(6)H(4)-OCH(3) moiety was in close proximity with H3 proton of the β-CD or methyl-β-CD cavity. Furthermore, we found that the solubility of EM011 in phosphate buffer saline (pH 7.4) was enhanced by ~11 fold and ~21 fold upon complexation with β-CD and methyl-β-CD, respectively. The enhanced dissolution of the drug CD-complexes in aqueous phase remarkably decreased their IC(50) to 28.5 μM (9-Br-Nos-β-CD) and 12.5 μM (9-Br-Nos-methyl-β-CD) in PC-3 cells compared to free EM011 (~200 μM). This is the first report to demonstrate the novel construction of cylcodextrin-based nanosupramolecular vehicles for enhanced delivery of EM011 that warrants in vivo evaluation for the superior management of prostate cancer.

  11. Flavonoids at the pharma-nutrition interface: Is a therapeutic index in demand?

    The consumption of flavonoid-rich foods could have beneficial effects on health. However, different classes of flavonoids have different effect on disease risk and the relationship between flavonoid intake and risk of disease appeared to be non-linear. Furthermore, contrarily to vitamins, there are no symptoms of deficiency for flavonoids; therefore, our body treats them like other xenobiotics. Therefore, a therapeutic index should be determined. Despite flavonoids are at the pharma-nutrition interface, drugs and foods are subject to different regulatory frameworks and there is no recommended daily allowance (RDA) for flavonoids. Relatively little is known about the efficacy, safety and underlying mechanisms of these bioactive compounds, especially when taken in concert with drugs. Flavonoids could act both as drugs and pro-drugs with pharmacological and toxicological promiscuity. Due to the low bioavailability, the gastrointestinal tract could be the primary target of flavonoids and metabolites. Different effects have been observed after acute and chronic consumption and bioavailability and bioactivity have high inter-individual variability. Furthermore, the difficulties in the design and in the interpretation of human intervention studies make difficult the establishment of a therapeutic index for flavonoids. Probably the concept of 'personalized nutrition' previously proposed could be the better approach. However, despite more studies are needed in order to establish a therapeutic index for each flavonoid subclasses, at the moment RDA of total flavonoids could be between 250-400 mg/d, respecting the seasonality of food sources.

  12. [As index patient into therapeutic alternatives?--Children in systemic family therapy and counseling].

    Since systemic therapy and counseling approaches have become established in child guidance, and children and adolescent psychiatry the understanding for children in the therapeutic context has also changed. They are part of the family system who, with their symptoms, point to restricting reality constructions and interaction patterns which create suffering (index patients). They are often treated correspondingly in the family setting. On this background this article investigates the special situation of children in the practice of systemic family therapy. The few results from studies from practice research dealing with this subject are compared with system-theoretical basic assumptions. The results indicate that the children are only insufficiently integrated into the therapy sessions and are excluded partly. They often experience the family discussions as being adult-oriented and feel that their needs and views are considered only slightly. Possible causes for this may be expecting too much emotionally and/or cognitively especially from younger children with family-oriented methods (such as circular questioning) as well as deficits in the training of family therapists. The closing thoughts on the therapeutic implications from the presented results include suggestions on methodical approaches more suitable for children and a reflected therapeutic attitude (transparency, participation, respect) towards children.

  13. Cerebral tissue oxygenation index and superior vena cava blood flow in the very low birth weight infant.

    BACKGROUND: Superior vena cava (SVC) flow assesses blood flow from the upper body, including the brain. Near infrared spectroscopy (NIRS) provides information on brain perfusion and oxygenation. AIM: To assess the relationship between cerebral tissue oxygenation index (cTOI) and cardiac output measures in the very low birth weight (VLBW) infant in the first day of life. METHODS: A prospective observational cohort study. Neonates with birth weight less than 1500 g (VLBW) were eligible for enrollment. Newborns with congenital heart disease, major congenital malformations and greater than Papile grade1 Intraventricular Haemorrhage on day 1 of life were excluded. Echocardiographic evaluation of SVC flow was performed in the first 24 h of life. Low SVC flow states were defined as a flow less than 40 mL\\/kg\\/min. cTOI was measured using NIRO 200 Hamamatsu. RESULTS: Twenty-seven VLBW neonates had both echocardiography and NIRS performed. The median (range) gestation was 29\\/40 (25 + 3 to 31 + 5 weeks) and median birth weight was 1.2 kg (0.57-1.48 kg). The mean (SD) TOI was 68.1 (7.9)%. The mean (SD) SVC flow was 70.36(39.5) mLs\\/kg\\/min. The correlation coefficient of cerebral tissue oxygenation and SVC flow was r = 0.53, p-value 0.005. There was a poor correlation between right and left ventricular output and cTOI which is not surprising considering the influence of intra- and extracardiac shunts. CONCLUSION: There is a positive relationship between cerebral TOI values and SVC flow in the very low birth infant on day one of life.

    In 1936, Holthusen theorized the probability of achieving tumor control and of developing normal tissue complications after radiotherapy as a function of radiation dose. This concept was formalized and further developed in 1975. Several concepts for improving the therapeutic gain had been anticipated, including the possibility of modulating the tumor/normal tissue differential response. Eight decades later, it is possible to review and analyze progress achieved in the knowledge of radiation-induced toxicity. The clinical developments using new technologies and biological modulators of radiation response have corroborated a posteriori this model, however, many questions remain unanswered. A few randomized trials have validated the benefit of modern irradiation techniques for improving the therapeutic index; but the level I evidence of a survival improvement is still lacking. In the field of bio-modulation, large meta-analyses have shown that concurrent chemotherapy improves local control in many cancer types. Clinical investigations using molecularly targeted therapies have been rather disappointing, with only one exception: head and neck squamous cell carcinoma. Numerous recent biological findings question the possibility to target tumor tissue without impacting normal tissue response. Moreover, the abscopal and bystander effects suggest that normal tissue irradiation should not be perceived only as a source of toxicity, but may also result in downstream therapeutic effects. This paper reexamines the multiple efforts made to modulate the tumor versus normal tissue differential response, which have translated into incremental therapeutic gain and highlights the ongoing effort to better understand the optimal integration of radiation biology, chemotherapeutic, novel drugs and novel technologies.

    The incidence of malignant melanoma is increasing at an alarming rate globally. Poor prognosis and extraordinarily low survival rates of malignant melanoma necessitates the development of new chemotherapeutic strategies. An emerging approach is to harness nanotechnology to optimize the existing chemotherapies. In the present study we have demonstrated that the delivery of doxorubicin using a nanotechnology-based platform significantly reduces the systemic toxicity of the drug, keeping unchanged its therapeutic efficacy in a mouse melanoma tumor model. Specifically we modified single-walled carbon nanotubes (CNTs) to conjugate a doxorubicin prodrug via a carbamate linker that cleaves enzymatically to cause temporal release of the active drug. The CNT-doxorubicin conjugate (CNT-Dox) induced time-dependent cell death in B16-F10 melanoma cells in vitro. The nanoparticle was rapidly internalized into the lysosome of melanoma cells and was retained in the subcellular compartment for over 24 h. In an in vivo melanoma model, treatment with the nanotube-doxorubicin conjugate abrogated tumor growth without the systemic side-effects associated with free doxorubicin. Our studies demonstrate that a simple and versatile CNT-based nanovector can be harnessed for the delivery of chemotherapy to melanoma, with increased therapeutic index.

    Various health communities have expressed concerns regarding whether average bioequivalence (BE) limits (80.00–125.00%) for the 90% confidence interval of the test-to-reference geometric mean ratio are sufficient to ensure therapeutic equivalence between a generic narrow therapeutic index (NTI) drug and its reference listed drug (RLD). Simulations were conducted to investigate the impact of different BE approaches for NTI drugs on study power, including (1) direct tightening of average BE lim...

    Full Text Available Background/Aims. This study aimed to establish optimal propofol anesthesia for therapeutic endoscopy, which has not been established. Methodology. We retrospectively investigated data on 89 patients who underwent upper-GI endoscopic submucosal dissection or endoscopic mucosal resection under anesthesia with propofol. Examined doses of propofol were changed according to efficacy and/or adverse events and classified into 5 periods. A bispectral index (BIS monitor was used at Period 5 to decrease the incidence of adverse events caused by oversedation. The initial dose of propofol was administered after bolus injection of pethidine hydrochloride (0.5 mg/kg, and 1.0 mL of propofol was added every minute until the patients fell asleep. Continuous and bolus infusion were performed to maintain sedation. When the patient moved or an adverse event occurred, the maintenance dose examined was increased or decreased by 5 mL/h regardless of body weight. Results. Dose combinations (introduction : maintenance and patient numbers for each period were as follows: Period 1 (n=27, 0.5 mg/kg : 5 mg/kg/h; Period 2 (n=11, 0.33 mg/kg : 3.3 mg/kg/h; Period 3 (n=7, 0.5 mg/kg : 3.3 mg/kg/h; Period 4 (n=14, 0.5 mg/kg : 2.5 mg/kg/h; Period 5 (n=30, 0.5 mg/kg : 2.5 mg/kg/h, using BIS monitor. During Period 5, an adverse event occurred in 10.0% of patients, which was lower than that for Periods 1–4. Conclusions. Period 5 propofol anesthesia with BIS protocol could be safe and useful for therapeutic endoscopy under deep sedation with spontaneous respiration.

    Levothyroxine is a narrow therapeutic index, and to avoid adverse effect associated with under or excessive dosage, the dose response is carefully titrated. The tablets are marketed with a score providing an option to split. However, there are no systematic studies evaluating the effect of splitting on dose accuracy, and current study was undertaken to evaluate effects of splitting and potential causes for uniformity failures by measuring assay and content uniformity in whole and split tablets. Stability was evaluated by assaying drug for a period of 8 weeks. Effect of formulation factors on splittability was evaluated by a systematic investigation of formulation factors by preparing levothyroxine tablets in house by varying the type of excipients (binder, diluent, disintegrant, glidant) or by varying the processing factors (granulating liquid, mixing type, compression pressure). The tablets were analyzed using novel analytical tool such as near infrared chemical imaging to visualize the distribution of levothyroxine. Assay was not significantly different for whole versus split tablets irrespective of method of splitting (hand or splitter), and splitting also had no measurable impact on the stability. Split tablets either by hand or splitter showed higher rate of content uniformity failures as compared to whole tablets. Tablet splitter produced more fragmentation and, hence, more content uniformity and friability failures. Chemical imaging data revealed that the distribution of levothyroxine was heterogeneous and was dependent on type of binder and the process used in the manufacture of tablets. Splitting such tablets could prove detrimental if sub- or super-potency becomes an issue.

    Several promising anticancer drug candidates have been sidelined owing to their poor physicochemical properties or unfavorable pharmacokinetics, resulting in high overall cost of drug discovery and development. Use of alternative formulation strategies that alleviate these issues can help advance new molecules to the clinic at a significantly lower cost. Tylocrebrine is a natural product with potent anticancer activity. Its clinical trial was discontinued following the discovery of severe central nervous system toxicities. To improve the safety and potency of tylocrebrine, we formulated the drug in polymeric nanoparticles targeted to the epidermal growth factor receptor (EGFR) overexpressed on several types of tumors. Through in vitro studies in different cancer cell lines, we found that EGFR targeted nanoparticles were significantly more effective in killing tumor cells than the free drug. In vivo pharmacokinetic studies revealed that encapsulation in nanoparticles resulted in lower brain penetration and enhanced tumor accumulation of the drug. Further, targeted nanoparticles were characterized by significantly enhanced tumor growth inhibitory activity in a mouse xenograft model of epidermoid cancer. These results suggest that the therapeutic index of drugs that were previously considered unusable could be significantly improved by reformulation. Application of novel formulation strategies to previously abandoned drugs provides an opportunity to advance new molecules to the clinic at a lower cost. This can significantly increase the repertoire of treatment options available to cancer patients.

    To ascertain predictors of initiation of brand-name versus generic narrow therapeutic index (NTI) drugs. Retrospective cohort study. Data from CVS Caremark were linked to Medicare claims and to U.S. census data. Individuals aged 65 and older who initiated an NTI drug in 2006 and 2007 (N = 36,832). Demographic, health service utilization, and geographic predictors of whether participants initiated a generic or brand-name version of their NTI drug were identified using logistic regression. Overall, 30,014 (81.5%) participants started on a generic version of their NTI drug. The most commonly initiated NTI drugs were warfarin (n = 17,790; 48%), levothyroxine (n = 10,779; 29%), and digoxin (n = 6,414; 17%). Older age (odds ratio (OR) = 1.12, 95% confidence interval (CI) = 1.02-1.22 comparing aged ≥ 85 with 65-74), higher burden of comorbidity (OR = 1.05, 95% CI = 1.04-1.07 for each 1-point increase in comorbidity score), and prior use of any generic drug (OR = 1.55, 95% CI = 1.29-1.87) were positively associated with generic drug initiation. Independent of other predictors, residing in the census block group with the highest generic use was positively associated with greater odds of generic NTI drug initiation (OR = 1.24, 95% CI = 1.14-1.35 compared with the lowest quintile). Demographic, health service utilization, and geographic characteristics are important determinants of whether individuals initiate treatment with a brand-name or generic NTI drug. These factors may contribute to disparities in care and highlight potential targets for educational campaigns. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

    The AmB-Cu(II) complex has recently been reported as an antifungal agent with reduced aggregation of AmB in aqueous solutions, increased anti C. albicans activity and lower toxicity against human cells in vitro. In the present work, investigations of the activity of the AmB-Cu (II) complex against fungal pathogens with varying susceptibility, including C. albicans and C. parapsilosis strains and intrinsically resistant A. niger, and cytotoxicity in normal human dermal fibroblasts (NHDF) in vitro were performed. For better understanding of the mechanism of reduced cytotoxicity and increased fungicidal activity, the influence of the AmB-Cu (II) complex on membrane integrity and accumulation of cellular reactive oxygen species (ROS) and mitochondrial superoxide was compared with that of conventional AmB. In the sensitive C. albicans and C. parapsilosis strains, the AmB-Cu(II) complex showed higher fungicidal activity (the MIC value was 0.35-0.7μg/ml for the AmB-Cu (II) complex, and 0.45-0.9μg/ml for Fungizone) due to increased induction of oxidative damage with rapid inhibition of the ability to reduce tetrazolium dye (MTT). In the NHDF cell line, the CC50 value was 30.13±1.53μg/ml for the AmB-Cu(II) complex and 17.46±1.24μg/ml for (Fungizone), therefore, the therapeutic index (CC50/MIC90) determined in vitro was 86.09-43.04 for the AmB-Cu(II) complex and 38.80-19.40 for Fungizone. The lower cytotoxicity of the AmB-Cu(II) complex in human cells resulted from lower accumulation of cellular and mitochondrial reactive oxygen species. This phenomenon was probably caused by the induction of successful antioxidant defense of the cells. The mechanism of the reduced cytotoxicity of the AmB-Cu(II) complex needs further investigation, but the preliminary results are very promising.

    Despite the recent successes of using immune modulatory Abs in patients with cancer, autoimmune pathologies resulting from the activation of self-reactive T cells preclude the dose escalations necessary to fully exploit their therapeutic potential. To reduce the observed and expected toxicities associated with immune modulation, here we describe a clinically feasible and broadly applicable approach to limit immune costimulation to the disseminated tumor lesions of the patient, whereby an agonistic 4-1BB oligonucleotide aptamer is targeted to the tumor stroma by conjugation to an aptamer that binds to a broadly expressed stromal product, VEGF. This approach was predicated on the premise that by targeting the costimulatory ligands to products secreted into the tumor stroma, the T cells will be costimulated before their engagement of the MHC-peptide complex on the tumor cell, thereby obviating the need to target the costimulatory ligands to noninternalizing cell surface products expressed on the tumor cells. Underscoring the potency of stroma-targeted costimulation and the broad spectrum of tumors secreting VEGF, in preclinical murine tumor models, systemic administration of the VEGF-targeted 4-1BB aptamer conjugates engendered potent antitumor immunity against multiple unrelated tumors in subcutaneous, postsurgical lung metastasis, methylcholantrene-induced fibrosarcoma, and oncogene-induced autochthonous glioma models, and exhibited a superior therapeutic index compared with nontargeted administration of an agonistic 4-1BB Ab or 4-1BB aptamer.

    AIM: Acute pancreatitis (AP) is a process with variable involvement of regional tissues or organ systems.Multifactorial scales included the Ranson, Acute Physiology and Chronic Health Evaluation (APACHE Ⅱ) systems and Balthazar computed tomography severity index (CTSI).The purpose of this review study was to assess the accuracy of CTSI, Ranson score, and APACHE Ⅱ score in course and outcome prediction of AP.METHODS: We reviewed 121 patients who underwent helical CT within 48 h after onset of symptoms of a first episode of AP between 1999 and 2003. Fourteen inappropriate subjects were excluded; we reviewed the 107 contrastenhanced CT images to calculate the CTSI. We also reviewed their Ranson and APACHE Ⅱ score. In addition, complications,duration of hospitalization, mortality rate, and other pathology history also were our comparison parameters.RESULTS: We classified 85 patients (79%) as having mild AP (CTSI <5) and 22 patients (21%) as having severe AP (CTSI ≥5). In mild group, the mean APACHE Ⅱ score and Ranson score was 8.6±1.9 and 2.4±1.2, and those of severe group was 10.2±2.1 and 3.1±0.8, respectively. The most common complication was pseudocyst and abscess and it presented in 21 (20%) patients and their CTSI was 5.9±1.4. A CTSI ≥5 significantly correlated with death,complication present, and prolonged length of stay.Patients with a CTSI ≥5 were 15 times to die than those CTSI <5, and the prolonged length of stay and complications present were 17 times and 8 times than that in CTSI <5,respectively.CONCLUSION: CTSI is a useful tool in assessing the severity and outcome of AP and the CTSI ≥5 is an index in our study. Although Ranson score and APACHE Ⅱ score also are choices to be the predictors for complications,mortality and the length of stay of AP, the sensitivity of them are lower than CTSI.

    Full Text Available In the past few years, the monoclonal antibody MIB-1 has been used by researchers in order to retrospectively study paraffin imbibed tumor fragments. The medulloblastoma is the most common malignant central nervous system tumor in childhood. The objectives were: determination of the mean Mib-1 LI value from these patients, as well as the prognostic value of the method.This retrospective study represents an analysis of the cellular proliferation index of posterior fossa medulloblastomas collected from 22 patients at A.C. Camargo Hospital, from January 1990 to December 1999. The histopathological diagnosis was confirmed by H&E and proliferative index (LI was achived with Mib-1 which detects proliferating cells during G1, G2, S and M phases.The results demostrated that the mean Mib-1 was 30,1%, and ranged from 5,2% to 62,0%.In conclusion, this method has prognostic value, has to be used as routine for patients harboring medulloblastomas and the ones who have PI greater than the mean value found in this study, should be treated aggressively.

    Various health communities have expressed concerns regarding whether average bioequivalence (BE) limits (80.00-125.00%) for the 90% confidence interval of the test-to-reference geometric mean ratio are sufficient to ensure therapeutic equivalence between a generic narrow therapeutic index (NTI) drug and its reference listed drug (RLD). Simulations were conducted to investigate the impact of different BE approaches for NTI drugs on study power, including (1) direct tightening of average BE limits and (2) a scaled average BE approach where BE limits are tightened based on the RLD's within-subject variability. Addition of a variability comparison (using a one-tailed F test) increased the difficulty for generic NTIs more variable than their corresponding RLDs to demonstrate bioequivalence. Based on these results, the authors evaluate the fully replicated, 2-sequence, 2-treatment, 4-period crossover study design for NTI drugs where the test product demonstrates BE based on a scaled average bioequivalence criterion and a within-subject variability comparison criterion.

    Hypothesis and aim. The large number of invalidating surgical interventions in patients suffering from lesions of the diabetic foot, the late recognition of the lesions and sometimes the wrongful interpretation of their severity, have made necessary a multi-parameter study of these types of patients and the elaboration of a therapeutic-prognostic index to guide the physician in adopting the adequate method of treatment. Starting with the therapeutic-prognostic index imagined by professor Traian Patrascu, we have elaborated a new therapeutic prognostic index, by adding new, statistically significant parameters, for the purpose of facilitating the surgical indication, depending on the lesion type. Methods. A number of 929 patients who were admitted at the Surgery Clinic of the “Dr. I. Cantacuzino” Hospital, between January 2013 and June 2014, have been analyzed, of whom 450 were evaluated retrospectively and 479 prospectively. Results. The new therapeutic prognostic index has been calculated for the retrospective lot, resulting into a concordance between the actual surgical intervention and the prognostic index of 79.4% and, for the patients evaluated prospectively, we have found a confirmation of the relation of 82.6% between the performed surgical intervention and the forecasted surgical intervention, by calculating the index. Discussion. The new therapeutic-prognostic index represents an easy method of establishing the therapeutic conduct of the patient suffering from lesions of the diabetic foot. It is of major use in preventing the execution of such surgical interventions that may be disproportionate compared to the severity of the lesions, especially in facilities where the pathology of the diabetic foot is less known.

    The advances in radiotherapy (3D-CRT, IMRT) have enabled high doses of radiation to be delivered with the least possible associated toxicity. However, the persistence of cancer (local recurrence after radiotherapy) despite these increased doses as well as distant failure suggesting the existence of micro-metastases, especially in the case of higher risk disease, have underscored the need for continued improvement in treatment strategies to manage local and micro-metastatic disease as definitively as possible. This has prompted the idea that an increase in the therapeutic index of radiotherapy might be achieved by combining it with in situ gene therapy. The goal of these combinatorial therapies is to maximize the selective pressure against cancer cell growth while minimizing treatment-associated toxicity. Major efforts utilizing different gene therapy strategies have been employed in conjunction with radiotherapy. We reviewed our and other published clinical trials utilizing this combined radio-genetherapy approach including their associated pre-clinical in vitro and in vivo models. The use of in situ gene therapy as an adjuvant to radiation therapy dramatically reduced cell viability in vitro and tumor growth in vivo. No significant worsening of the toxicities normally observed in single-modality approaches were identified in Phase I/II clinical studies. Enhancement of both local and systemic T-cell activation was noted with this combined approach suggesting anti-tumor immunity. Early clinical outcome including biochemical and biopsy data was very promising. These results demonstrate the increased therapeutic efficacy achieved by combining in situ gene therapy with radiotherapy in the management of local prostate cancer. The combined approach maximizes tumor control, both local-regional and systemic through radio-genetherapy induced cytotoxicity and anti-tumor immunity.

    Radiotherapy is a key component of cancer treatment. Because of its importance, there has been high interest in developing agents and strategies to further improve the therapeutic index of radiotherapy. DNA double-strand repair inhibitors (DSBRIs) are among the most promising agents to improve radiotherapy. However, their clinical translation has been limited by their potential toxicity to normal tissue. Recent advances in nanomedicine offer an opportunity to overcome this limitation. In this study, we aim to demonstrate the proof of principle by developing and evaluating nanoparticle (NP) formulations of KU55933, a DSBRI. We engineered a NP formulation of KU55933 using nanoprecipitation method with different lipid polymer nanoparticle formulation. NP KU55933 using PLGA formulation has the best loading efficacy as well as prolonged drug release profile. We demonstrated that NP KU55933 is a potent radiosensitizer in vitro using clonogenic assay and is more effective as a radiosensitizer than free KU55933 in vivo using mouse xenograft models of non-small cell lung cancer (NSCLC). Western blots and immunofluorescence showed NP KU55933 exhibited more prolonged inhibition of DNA repair pathway. In addition, NP KU55933 leads to lower skin toxicity than KU55933. Our study supports further investigations using NP to deliver DSBRIs to improve cancer radiotherapy treatment.

    Since systemic treatment of neuropathic plantar ulcers in diabetics (DNPU) has so far been rather ineffective, recent reports of successful management of DNPU by short-term retrograde transvenous leg perfusion (RVP) by South American angiologists encouraged us to apply this treatment method in diabetics suffering from chronic DNPU. Hence, in a prospective comparative clinical trial started in 1989 we have treated 45 male diabetics suffering from DNPU with the same daily doses of netilmycin, administered either in systemic venous infusions (SVI: n = 21, three times/day) or in RVP (n = 24, once/day). After 10 consecutive days of treatment, ulcers had closed in 8 of the 24 patients treated with RVP, as against 3 of the 21 treated with SVI. Diminution of the ulcer area by > 30% including full debridement was achieved in 10/24 of the RVP cases (SVI: 4/21). During 6 months of follow-up, amputation of toes or forefoot was necessary in only 1 patient in the RVP group, but in 4 in the SVI group. Partial restitution of osteolytic damage was observed in some cases after RVP. Our results show that regional netilmycin therapy given by the RVP procedure is clearly superior to equal netilmycin doses administered by SVI for the treatment of DNPU. RVP can be recommended in DNPU, particularly when the ulcers are complicated by infections.

To prospectively evaluate the effect of intravitreal bevacizumab on aqueous levels of interleukin-6 (IL-6 and vascular endothelial growth factor (VEGF in patients with exudative age-related macular degeneration (AMD and correlate clinical outcomes with cytokine levels. Methods. 30 eyes of 30 patients with exudative AMD underwent intravitreal injection of bevacizumab three times at monthly intervals. The aqueous samples prior to the 1st injection (baseline and 3rd injection were analyzed for VEGF and IL-6 levels. Subjects were subgrouped based upon change in the central subfield (CSF macular thickness on SD-OCT at 8 weeks. Group 1 included patients (n=14 with a decrease in CSF thickness greater than 10% from the baseline (improved group. Group 2 included patients (n=16 who had a decrease in CSF thickness 10% or less (treatment-resistant. Results. In subgroup analysis, in both groups 1 and 2 patients, compared to aqueous VEGF, aqueous IL-6 levels showed a better correlation with CSF thickness on SD-OCT (r=0.72 and 0.71, resp.. Conclusions. Aqueous IL-6 may be an important marker of treatment response or resistance in wet macular degeneration. Future therapeutic strategies may include targeted treatment against both VEGF and IL-6, in patients who do not respond to anti-VEGF treatment alone.

    Full Text Available Background: As the world moves toward elimination of leprosy, persistence of infective cases in endemic pockets remains a significant problem. The use of clinical criteria to decide the paucibacillary (PB versus multibacillary (MB regimens has greatly simplified therapy at the field setting. However, a small but significant risk of under-treatment of so-called "PB" cases which actually have significant bacillary load exists. This study was undertaken to assess this risk and compare two methods of assessment of bacillary load, namely bacillary index on slit skin smear (BIS versus bacillary index of granuloma (BIG. Aims: To compare BIS with BIG on skin biopsy in consecutive untreated cases of leprosy. Materials and Methods: This prospective study was conducted over a period of 12 months, wherein new untreated patients with leprosy were consecutively recruited. After a thorough clinical examination, each patient underwent slit skin smear (SSS where the BIS was calculated. The same patient also underwent a skin biopsy from a clinical lesion where, the BIG was calculated. SSS and skin biopsy for BIS and BIG respectively were repeated for all patients at the end of therapy for comparison. All patients received therapy according to World Health Organization-Multidrug Therapy Guidelines. Results: The BIG was positive in all cases where the BIS was positive. Significantly, BIG was positive in three cases of borderline tuberculoid leprosy with <5 lesions who received PB regimen, whereas the BIS was negative in all three cases. Conclusion: This study suggests that BIG may be a better indicator of the true bacillary load in leprosy as compared to BIS. Its role in management is significant, at least in tertiary care centers to prevent "under-treatment" of so called PB cases, which may actually warrant MB regimens.

    The objective of this study was to evaluate the reliability and validity of the joint dysfunction index (JDI) for assessment of therapeutic efficacy for Kashin-Beck disease (KBD). In an initial survey, completed questionnaires were obtained from 276 of 281 patients (98.2 %). A follow-up survey was completed with 64 KBD patients among 276 cases. A third survey selected 60 KBD patients who underwent intra-articular injection of sodium hyaluronate in the knees ascertained from the findings of the second questionnaire. Reliability was assessed using test-retest, "split-half" reliability and Cronbach's alpha coefficient. Factor analysis and item-to-domain correlation were used to analyze validity. The coefficient of variation (CV) was used to measure the sensitivity of scale. Feasibility assessment included consideration of completion time, rate of recovery, and time of completion. Reliability analysis comprised a test-retest correlation coefficient of 0.404-0.546 and a kappa test of 0.404-0.546. Internal consistency analysis comprised a Cronbach alpha coefficient of 0.689 and a split-half coefficient of 0.677. Principal component factor analysis for validity testing extracted a common factor with a cumulative variance contribution of 45.44 %. The JDI score from 276 KBD cases revealed no significant difference associated with age, gender, education, or the body mass index. Sensitivity analysis showed that there was no significant difference between pre-treatment and post-treatment values, with a CV of 96.55-172.06 %. In conclusion, the JDI can be used to evaluate the efficacy of agents used to treat KBD.

    2014-01-01

    Full Text Available The present study was designed to gain insight into the antiproliferative activity of ethanolic neem leaves extract (ENLE alone or in combination with cisplatin by cell viability assay on human breast (MCF-7 and cervical (HeLa cancer cells. Nuclear morphological examination and cell cycle analysis were performed to determine the mode of cell death. Further, to identify its molecular targets, the expression of genes involved in apoptosis, cell cycle progression, and drug metabolism was analyzed by RT-PCR. Treatment of MCF-7, HeLa, and normal cells with ENLE differentially suppressed the growth of cancer cells in a dose- and time-dependent manner through apoptosis. Additionally, lower dose combinations of ENLE with cisplatin resulted in synergistic growth inhibition of these cells compared to the individual drugs (combination index <1. ENLE significantly modulated the expression of bax, cyclin D1, and cytochrome P450 monooxygenases (CYP 1A1 and CYP 1A2 in a time-dependent manner in these cells. Conclusively, these results emphasize the chemopreventive ability of neem alone or in combination with chemotherapeutic treatment to reduce the cytotoxic effects on normal cells, while potentiating their efficacy at lower doses. Thus, neem may be a prospective therapeutic agent to combat gynecological cancers.

    Full Text Available The last twelve years have witnessed the development of new therapies for relapsing-remitting multiple sclerosis that demonstrate increased efficacy relative to previous therapies. Many of these new drugs target the inflammatory phase of disease by manipulating different aspects of the immune system. While these new treatments are promising, the development of therapies for patients with progressive multiple sclerosis remains a significant challenge. We discuss the distinct mechanisms that may contribute to these two types of multiple sclerosis and the implications of these differences in the development of new therapeutic targets for this debilitating disease.

  7. PERSISTENT LEFT SUPERIOR VENACAVA

    Full Text Available A Persistent Left Superior Venacava (PLSVC is the most common variation of the thoracic venous system and rare congenital vascular anomaly and is prevalent in 0.3% of the population. It may be associated with other cardiovascular abnormalities including atrial septal defect, bicuspid aortic valve, coarctation of aorta, coronary sinus ostial atresia, and cor triatriatum. Incidental rotation of a dilated coronary sinus on echocardiography should raise the suspicion of PLSVC. The diagnosis should be confirmed by saline contrast echocardiography. Condition is usually asymptomatic. Here we present a rare case of persistent left superior vena cava presented in OPD with dyspnoea & palpitations.

  8. INDEXING AND INDEX FUNDS

    Full Text Available Proponents of the efficient market hypothesis believe that active portfolio management is largely wasted effort and unlikely to justify the expenses incurred. Therefore, they advocate a passive investment strategy that makes no attempt to outsmart the market. One common strategy for passive management is indexing where a fund is designed to replicate the performance of a broad-based index of stocks and bonds. Traditionally, indexing was used by institutional investors, but today, the use of index funds proliferated among individual investors. Over the years, both international and domestic index funds have disproportionately outperformed the market more than the actively managed funds have.

  9. The lumbar lordosis index: a new ratio to detect spinal malalignment with a therapeutic impact for sagittal balance correction decisions in adult scoliosis surgery.

    Sagittal malalignment is frequently observed in adult scoliosis. C7 plumb line, lumbar lordosis and pelvic tilt are the main factors to evaluate sagittal balance and the need of a vertebral osteotomy to correct it. We described a ratio: the lumbar lordosis index (ratio lumbar lordosis/pelvic incidence) (LLI) and analyzed its relationships with spinal malalignment and vertebral osteotomies. 53 consecutive patients with a surgical adult scoliosis had preoperative and postoperative full spine EOS radiographies to measure spino-pelvic parameters and LLI. The lack of lordosis was calculated after prediction of theoretical lumbar lordosis. Correlation analysis between the different parameters was performed. All parameters were correlated with spinal malalignment but LLI is the most correlated parameter (r = -0.978). It is also the best parameter in this study to predict the need of a spinal osteotomy (r = 1 if LLI <0.5). LLI is a statistically validated parameter for sagittal malalignment analysis. It can be used as a mathematical tool to detect spinal malalignment in adult scoliosis and guides the surgeon decision of realizing a vertebral osteotomy for adult scoliosis sagittal correction. It can be used as well for the interpretation of clinical series in adult scoliosis.

  10. The value of population pharmacokinetics and simulation for postmarketing safety evaluation of dosing guidelines for drugs with a narrow therapeutic index: buflomedil as a case study.

    Population pharmacokinetics and simulation techniques currently play an important role in new drug development. This paper illustrates the potential value of those methods in postmarketing safety assessment, using buflomedil in elderly patients as an example. We retrospectively assessed the risk of buflomedil overdosing associated with the latest dosing recommendations of the French Drug Agency (AFSSAPS). First, buflomedil concentrations measured in 24 elderly patients were analysed with a nonparametric population approach. Then, the pharmacokinetic model was used to perform a 1000-patient Monte Carlo simulation for the two recommended buflomedil dosage regimens. The maximum concentrations calculated after 10 days of therapy were compared with levels observed in reported cases of toxicity to assess the probability of overdosing. A three-compartment model best fit concentration data. Population predictions showed little bias (-0.14 mg/L) and good precision (8.73 mg(2) /L(2)). Overall results of the simulation study showed that the application of the two recommended dosage regimens of buflomedil was associated with overdosing (C(max) > 10 mg/L) and potential toxicity in 2.9% of geriatric patients. In patients with mild renal impairment, who may receive the higher-dosage regimen by therapeutic error, the probability of overdosing was 6.2%. Despite specific dosing recommendations in case of renal impairment, this study shows that the use of buflomedil could be associated with significant risk of overdosing in geriatric patients. Such results might have enhanced decision-making when buflomedil safety was reassessed by AFSSAPS in 2006. The retrospective case of buflomedil illustrates how these methods may be valuable in postmarketing safety evaluation of potentially toxic drugs.

    We aimed to evaluate the efficacy of tocilizumab in patients with rheumatoid arthritis (RA), using the clinical disease activity index (CDAI), and to determine the baseline variables associated with CDAI remission. Fifty-eight patients with active RA were enrolled. We tried to evaluate whether baseline variables were associated with CDAI remission at 24 weeks. Twenty-two of the 58 patients (37.9%) had received tumor necrosis factor (TNF) inhibitors. The continuation rate of tocilizumab at 24 weeks was 87.9%. The seropositivity rates of IgM-rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibodies at baseline were both 91.4%. The rate of CDAI remission at 24 weeks was 20.7%. We selected baseline variables including age, gender, duration of disease, concomitant use of glucocorticoids, concomitant use of methotrexate (MTX), previous anti-TNF therapy, titer of anti-CCP antibodies (high or low toward median), titer of IgM-RF (high or low toward median), and CDAI, and found that a high titer of IgM-RF was the only variable to be associated with CDAI remission, according to univariate and logistic regression analyses. This is a new finding, and may be specific to tocilizumab as compared with previous observations in anti-TNF therapy.

  15. Statistics of superior records

    Ben-Naim, E.; Krapivsky, P. L.

    2013-08-01

    We study statistics of records in a sequence of random variables. These identical and independently distributed variables are drawn from the parent distribution ρ. The running record equals the maximum of all elements in the sequence up to a given point. We define a superior sequence as one where all running records are above the average record expected for the parent distribution ρ. We find that the fraction of superior sequences SN decays algebraically with sequence length N, SN˜N-β in the limit N→∞. Interestingly, the decay exponent β is nontrivial, being the root of an integral equation. For example, when ρ is a uniform distribution with compact support, we find β=0.450265. In general, the tail of the parent distribution governs the exponent β. We also consider the dual problem of inferior sequences, where all records are below average, and find that the fraction of inferior sequences IN decays algebraically, albeit with a different decay exponent, IN˜N-α. We use the above statistical measures to analyze earthquake data.

    Full Text Available Flexible AC transmission system (FACTS has the control characteristics of efficiency, flexibility and reliability. The introduction of FACTS in power system is superior to any other control methods, and different FACTS devices have different features. In this paper, a comprehensive evaluation index system is developed to study a variety of comparisons on different FACTS devices. The proposed index takes power flow controllability as its main indicator, and loss reduction, static voltage stability improvement and load shedding reduction as complementary indicators. Finally, the peak load case in 2016 of a province is adopted for case studies. The results not only show that the proposed comprehensive evaluation index is systematic, scientific, practical, but also show the superiority of unified power flow controller (UPFC.

In the area of the jugular foramen is the near superior ganglion of the 10th cranial nerve. In this area were found 1.48 (mean value) anastomoses with the 9th cranial nerve. 11.34 mm below the margo terminalis sigmoidea branches off the ramus internus of the accessory nerve which has a length of 9.75 mm. Further anastomoses with the 10th cranial nerve were found. The inferior ganglion of the 10th nerve had a length of 25.47 mm and a diameter of 3.46 mm. Five mm below the ganglion the 10th nerve had a width of 2.9 and a thickness of 1.5 mm. The mean length of the superior sympathetic ganglion was 26.6 mm, its width 7.2 and its thickness 3.4 mm. In nearly all specimens anastomoses of the superior sympathetic ganglion with the ansa cervicalis profunda and the inferior ganglion of the 10th cranial nerve were found. The superior laryngeal nerve branches off about 36 mm below the margo terminalis sigmoidea. The width of this nerve was 1.9 mm, its thickness 0.8 mm on the right and 1.0 mm on the left side. The division in the internal and external rami was found about 21 mm below its origin. Between the n. vagus and thyreohyoid membrane the ramus internus had a length of 64 mm, the length of external ramus between the vagal nerve and the inferior pharyngeal constrictor muscle was 89 mm.

  3. What are Millian Qualitative Superiorities?

    2008-04-01

    Full Text Available In an article published in Prolegomena 2006, Christoph Schmidt-Petri has defended his interpretation and attacked mine of Mill’s idea that higher kinds of pleasure are superior in quality to lower kinds, regardless of quantity. Millian qualitative superiorities as I understand them are infinite superiorities. In this paper, I clarify my interpretation and show how Schmidt-Petri has misrepresented it and ignored the obvious textual support for it. As a result, he fails to understand how genuine Millian qualitative superiorities determine the novel structure of Mill’s pluralistic utilitarianism, in which a social code of justice that distributes equal rights and duties takes absolute priority over competing considerations. Schmidt-Petri’s own interpretation is a non-starter, because it does noteven recognize that Mill is talking about different kinds of pleasant feelings, such that the higher kinds are intrinsically more valuable than the lower. I conclude by outlining why my interpretation is free of any metaphysical commitment to the “essence” of pleasure.

    Marulli, Giuseppe; Battistella, Lucia; Mammana, Marco; Calabrese, Francesca; Rea, Federico

    2016-06-01

    Superior Sulcus Tumors, frequently termed as Pancoast tumors, are a wide range of tumors invading the apical chest wall. Due to its localization in the apex of the lung, with the potential invasion of the lower part of the brachial plexus, first ribs, vertebrae, subclavian vessels or stellate ganglion, the superior sulcus tumors cause characteristic symptoms, like arm or shoulder pain or Horner's syndrome. The management of superior sulcus tumors has dramatically evolved over the past 50 years. Originally deemed universally fatal, in 1956, Shaw and Paulson introduced a new treatment paradigm with combined radiotherapy and surgery ensuring 5-year survival of approximately 30%. During the 1990s, following the need to improve systemic as well as local control, a trimodality approach including induction concurrent chemoradiotherapy followed by surgical resection was introduced, reaching 5-year survival rates up to 44% and becoming the standard of care. Many efforts have been persecuted, also, to obtain higher complete resection rates using appropriate surgical approaches and involving multidisciplinary team including spine surgeon or vascular surgeon. Other potential treatment options are under consideration like prophylactic cranial irradiation or the addition of other chemotherapy agents or biologic agents to the trimodality approach.

    2004-01-01

    The use of ultrasound in medicine is now quite commonplace, especially with the recent introduction of small, portable and relatively inexpensive, hand-held diagnostic imaging devices. Moreover, ultrasound has expanded beyond the imaging realm, with methods and applications extending to novel therapeutic and surgical uses. These applications broadly include: tissue ablation, acoustocautery, lipoplasty, site-specific and ultrasound mediated drug activity, extracorporeal lithotripsy, and the enhancement of natural physiological functions such as wound healing and tissue regeneration. A particularly attractive aspect of this technology is that diagnostic and therapeutic systems can be combined to produce totally non-invasive, imageguided therapy. This general lecture will review a number of these exciting new applications of ultrasound and address some of the basic scientific questions and future challenges in developing these methods and technologies for general use in our society. We shall particularly emphasize the use of High Intensity Focused Ultrasound (HIFU) in the treatment of benign and malignant tumors as well as the introduction of acoustic hemostasis, especially in organs which are difficult to treat using conventional medical and surgical techniques.

    Full Text Available Genetic interaction networks that underlie most human diseases are highly complex and poorly defined. Better-defined networks will allow identification of a greater number of therapeutic targets. Here we introduce our Yeast Augmented Network Analysis (YANA approach and test it with the X-linked spinal muscular atrophy (SMA disease gene UBA1. First, we express UBA1 and a mutant variant in fission yeast and use high-throughput methods to identify fission yeast genetic modifiers of UBA1. Second, we analyze available protein-protein interaction network databases in both fission yeast and human to construct UBA1 genetic networks. Third, from these networks we identified potential therapeutic targets for SMA. Finally, we validate one of these targets in a vertebrate (zebrafish SMA model. This study demonstrates the power of combining synthetic and chemical genetics with a simple model system to identify human disease gene networks that can be exploited for treating human diseases.

  19. The sentence superiority effect revisited.

    Science.gov (United States)

    Snell, Joshua; Grainger, Jonathan

    2017-11-01

    A sentence superiority effect was investigated using post-cued word-in-sequence identification with the rapid parallel visual presentation (RPVP) of four horizontally aligned words. The four words were presented for 200ms followed by a post-mask and cue for partial report. They could form a grammatically correct sentence or were formed of the same words in a scrambled agrammatical sequence. Word identification was higher in the syntactically correct sequences, and crucially, this sentence superiority effect did not vary as a function of the target's position in the sequence. Cloze probability measures for words at the final, arguably most predictable position, revealed overall low values that did not interact with the effects of sentence context, suggesting that these effects were not driven by word predictability. The results point to a level of parallel processing across multiple words that enables rapid extraction of their syntactic categories. These generate a sentence-level representation that constrains the recognition process for individual words, thus facilitating parallel word processing when the sequence is grammatically sound.

    Objective:To study the differences in superior thyroid artery and inferior thyroid artery blood flow spectrum parameters in subacute thyroiditis. Methods:A Total of 40 cases of patients with subacute thyroiditis and 40 cases of healthy volunteers were selected for study and enrolled in pathology group and control group respectively, color Doppler ultrasonography was conducted to detect peak blood flow velocities (Vmax) of superior thyroid artery and inferior thyroid artery as well as resistance index (RI), and serum was collected to detect thyroid hormone contents, infection indexes and oxidative stress indexes. Results:Peak blood flow velocities Vmax of superior thyroid artery and inferior thyroid artery of pathology group were significantly higher than those of control group, and resistance index RI was not different from that of control group;FT3, FT4, TT3, TT4, ESR, CRP, PCT and MDA of pathology group were significantly higher than those of control group, and SOD and TAOC were significantly lower than those of control group;Vmax of superior thyroid artery and inferior thyroid artery were positively correlated with FT3, FT4, TT3, TT4, ESR, CRP, PCT and MDA, and negatively correlated with SOD and TAOC. Conclusion:Peak blood flow velocities (Vmax) of superior thyroid artery and inferior thyroid artery in subacute thyroiditis are significantly accelerated, Vmax has good consistency with thyroid hormone contents, infection indexes and oxidative stress indexes, and it can accurately assess the severity of the disease.

    Full Text Available Before initiating the building operations for the «Palos Verdes» School, the site was divided into two large horizontal surfaces, at different levels. The lower one served to accommodate the playing fields, a car park, the physical training building, and shop and ancillary buildings. On the higher of these two surfaces, and to the West of the access road, there is a car park and also the building and plot of ground devoted to agricultural technology, as well as the literary studies and general purpose buildings. As a complement to these, there is a series of blocks, arranged in parallel rows, which house the administrative offices, the art school, the craft's school, the general classrooms, and those devoted to higher education. The fascinating aspect of this school is the outstanding penetration of the architect's mind into the essential function of the project. Its most evident merit is the sense of comradeship and harmony that permeates the whole architectural manifold.Antes de construir el complejo escolar «Palos Verdes» se comenzó por crear, en el terreno, dos grandes mesetas a niveles diferentes. Sobre el inferior se organizaron: los campos de juegos, de deportes, un aparcamiento, el edificio para educación física y los destinados a tiendas y servicios. Sobre la meseta superior, al oeste de la vía de acceso, se dispuso un aparcamiento y el edificio y campo para adiestramiento agrícola; al este, otro aparcamiento, el edificio dedicado a materias literarias, y el destinado a usos múltiples. Completan las instalaciones de la escuela una serie de bloques paralelos: la administración, la escuela de arte, las clases de trabajos manuales, las aulas de enseñanzas generales, y las de los cursos superiores. Lo fascinante de este complejo escolar es la perfecta y magistral compenetración del arquitecto con el tema proyectado, y su mayor mérito, la sensación de cordialidad y armonía con el ambiente.

    Objective: To observe and compare clinical therapeutic effect of acupuncture and moxibustion at different acupoint groups in stroke patients in the convalescence stage. Methods: Sixty stroke patients were evenly randomized into yin-meridian group and yang-meridian group. On the basis of the treatment with Chinese and Western medicines, these stroke patients of two groups were treated mainly by acupuncture of acupoints of yin meridians such as Jiquan (极泉HT 1), Tongli (通里HT 5), Neiguan (内关PC 6), etc., and those of yang meridians as Jianyu (肩NFDA1 LI 15), Quchi (曲池 LI 11), Shousanli (手三里LI 10), etc. Respectively. After 30 days' treatment, the therapeutic effect was evaluated by using American National Institutes of Health Stroke Scale (NIHSS), Hamilton Depression (HAMD) Rating Scale, Mini-Mental State Examination (MMSE), Barthel Index and Activities of Daily Living (ADL) Scale. Results: Following treatment, the therapeutic effect of yin-meridian group was significantly superior to that of yang-meridian group in improving stroke patients' neurological deficits [Level B: 50% (15/30) vs 20% (6/30)] and ADL [Level Ⅱ: 40% (12/30) vs 13.3% (4/30)]. No significant difference was found between two groups in the neurological impairment domains. Conclusion: Acu-moxibustion of acupoints of yin meridians is superior to acupoints of yang meridians in improving stroke patients' neurological impairment and daily living activities.

    Full Text Available The Redwood highway, through the Californian forest, runs on a viaduct, as it crosses a mountain slope of about 45° inclination. The firm ground is fairly deep, and as an additional constructional difficulty, it was necessary to respect the natural beauty of the countryside. A structure of portal frames were built, forming a number of short spans. These spans were bridged with metal girders, on which a 19 m wide deck was placed. The columns are hollow and have a transversal cross beam, to join each pair. There was difficulty in excavating the foundations for the columns, as it was necessary to dig through the soft top soil, and also prevent this soil from hurting the trunks of the forest trees. Another significant difficulty in the construction of this viaduct was the access to the working site, since there were no suitable platforms from which to operate the appropriate machinery. This made it necessary to do a lot of the work by manual operation. As one of the edges of the deck is very close to the mountain side, a supporting beam was erected on this side. It was made of concrete, on metal piles. The formwork for the deck structure was placed on the concrete stems of the supporting piles.La autopista denominada Redwood (California salva, con un paso superior, la ladera de un bosque cuya pendiente es del 1/1.

    Dysregulated inflammation is a central pathological process in diverse disease states. Traditionally, therapeutic approaches have sought to modulate the pro- or anti-inflammatory limbs of inflammation, with mixed success. However, insight into the pathways by which inflammation is resolved has highlighted novel opportunities to pharmacologically manipulate these processes - a strategy that might represent a complementary (and perhaps even superior) therapeutic approach. This Review discusses the state of the art in the biology of resolution of inflammation, highlighting the opportunities and challenges for translational research in this field.

    2014-02-01

    We report here a rare case of anterior superior iliac spine avulsion fracture that presented initially as meralgia paraesthetica. A 14-year-old male sprinter presented with anterior superior iliac spine avulsion fracture, which was not observed on initial plain radiograph of the hip, but was diagnosed by ultrasound. Both clinical presentations and electrophysiological studies indicated meralgia paraesthetica. The lateral femoral cutaneous nerve of the thigh was probably compressed by an inguinal haematoma resulting from sartorius muscle strain, which was detected on musculoskeletal ultrasound. Computed tomography of the pelvis confirmed anterior superior iliac spine avulsion fracture. Meralgia paraesthetica in adolescents can be due to anterior superior iliac spine avulsion fracture. Sonography is a valuable tool for screening for muscular haematoma and occult fractures, which may allow clinicians to diagnose the nature of the muscle injury, and thus guide the most appropriate therapeutic strategy.

    Awareness with explicit recall of intra-operative events is a rare and distressing complication that may lead to severe psychological symptoms. Candidate depth of anesthesia monitors have been developed, partly with the aim of preventing this complication. Despite conflicting results from clinical trials and the lack of incisive validation, such monitors have enjoyed widespread clinical adoption, in particular the bispectral index. The American Society of Anesthesiologists has called for adequately powered and rigorously designed clinical trials to determine whether the use of such monitors decreases the incidence of awareness in various settings. The aim of this study is to determine with increased precision whether incorporating the bispectral index into a structured general anesthesia protocol decreases the incidence of awareness with explicit recall among a subset of surgical patients at increased risk for awareness and scheduled to receive an inhalation gas-based general anesthetic. BAG-RECALL is a multi-center, randomized, controlled clinical trial, in which 6,000 patients are being assigned to bispectral index-guided anesthesia (target range, 40 to 60) or end-tidal anesthetic gas-guided anesthesia (target range, 0.7 to 1.3 age-adjusted minimum alveolar concentration). Postoperatively, patients are being assessed for explicit recall at two intervals (0 to 72 hours, and 30 days after extubation). The primary outcome of the trial is awareness with explicit recall. Secondary outcomes include postoperative mortality, psychological symptoms, intensive care and hospital length of stay, average anesthetic gas administration, postoperative pain and nausea and vomiting, duration of stay in the recovery area, intra-operative dreaming, and postoperative delirium. This trial has been designed to complement two other clinical trials: B-Unaware and MACS (ClinicalTrials.gov numbers, NCT00281489 and NCT00689091).

    [Objective] To observe the indexes for recent therapeutic effect of the different methods of hyperbaric oxygen (HBO) therapy on improving patients with traumatic brain injury accompanied by arousal disorders.[Methods]Sixty-five patients with traumatic brain injury accompanied by arousal disorders, who were treated in hospital in recent years, were successively selected. All the enrolled subjects accepted the HBO therapy, the pressure was 0.22 Mpa, and the stable oxygen uptake duration was 60 min/time, once or twice a day, and 6 ~12 times/week for a total of 4 weeks. The subjects were grouped according to the different HBO therapeutic methods: (1) grouping by therapeutic frequency: more frequency group (twice a day, n = 29) and fewer frequency group (twice a day, n =36). (2) grouping by therapeutic time: early therapy group (accepted therapy within 10 days, n = 35) and late therapeutic group (accepted therapy after 10 days, n = 30). All the patients were evaluated with the Glasgow Coma Scale (GCS) before and after therapy, respectively. [Results]The average days of coma and average length of stay in the more frequency group and early therapy group were obviously lower than those in the fewer frequency group and late therapeutic group (P < 0.01). The scores of GSC and DRS in the more frequency group and early therapy group after therapy were obviously better than those before therapy, and were also better than those in the fewer frequency group and late therapeutic group ( P < 0.05 ~ 0.01).[Conclusion]Early HBO therapy at more frequencies has more obvious influence on accelerating arousal and on the indexes for the recent therapeutic effect in patients with traumatic brain injury accompanied by arousal disorders.%[目的]观察不同高压氧(hyperbaric oxygen,HBO)治疗方法改善脑外伤觉醒障碍患者的近期疗效指标.[方法]连续选择近年来我院住院治疗脑外伤觉醒障碍患者65例,入选对象均接受了HBO治疗,压力为0.22 MPa

    Full Text Available Abstract Introduction Superior mesenteric artery syndrome is a rare cause of upper intestinal obstruction resulting from compression of the duodenum by the superior mesenteric artery and abdominal aorta. Case presentation We describe a case of superior mesenteric artery syndrome in a 61-year-old Japanese man with non-small cell lung cancer who had been treated with cisplatin-containing chemotherapy and had lost 7 kg in weight. The diagnosis was confirmed by the typical findings of abdominal computed tomography showing distended stomach resulting from compression of the third portion of the duodenum and reduction of an aortomesenteric distance and aortomesenteric angle. Conclusions This case highlights the importance of considering the possibility of superior mesenteric artery syndrome in patients treated with chemotherapy, especially those presenting with a low body mass index and showing weight loss during chemotherapy.

    Clinical utility of phosphodiesterase 4 (PDE4) inhibitors as anti-inflammatory agents has, to date, been limited by adverse effects including nausea and emesis, making accurate assessment of emetic versus anti-inflammatory potencies critical to the development of inhibitors with improved therapeutic indices. In the present study we determined the in vitro and in vivo anti-inflammatory potencies of the first-generation PDE4 inhibitor, rolipram, the second-generation inhibitors, roflumilast and cilomilast, and a novel third generation inhibitor, 1-ethyl-5-{5-[(4-methyl-1-piperazinyl)methyl]-1,3,4-oxadiazol-2-yl}-N-(tetrahydro-2H-pyran-4-yl)-1H-pyrazolo[3,4-b]pyridin-4-amine (EPPA-1). The rank-order potency against lipopolysaccharide (LPS)-induced tumor necrosis factor-alpha production by human peripheral blood mononuclear cells was roflumilast (IC(50) = 5 nM) > EPPA-1 (38) > rolipram (269) > cilomilast (389), and against LPS-induced pulmonary neutrophilia in the rat was EPPA-1 (D(50) = 0.042 mg/kg) > roflumilast (0.24) > rolipram (3.34) > cilomilast (4.54). Pica, the consumption of non-nutritive substances in response to gastrointestinal stress, was used as a surrogate measure for emesis, giving a rank-order potency of rolipram (D(50) = 0.495 mg/kg) > roflumilast (1.6) > cilomilast (6.4) > EPPA-1 (24.3). The low and high emetogenic activities of EPPA-1 and rolipram, respectively, detected in the pica model were confirmed in a second surrogate model of emesis, reversal of alpha(2)-adrenoceptor-mediated anesthesia in the mouse. The rank order of therapeutic indices derived in the rat [(pica D(50))/(neutrophilia D(50))] was EPPA-1 (578) > roflumilast (6.4) > cilomilast (1.4) > rolipram (0.15), consistent with the rank order derived in the ferret [(emesis D(50))/(neutrophilia D(50))]. These data validate rat pica feeding as a surrogate for PDE4 inhibitor-induced emesis in higher species, and identify EPPA-1 as a novel PDE4 inhibitor with an improved therapeutic index.

    Conclusions: Maximal resection and radiochemotherapy treatment completion are associated with longer OS, and age alone should not preclude elderly patients from receiving surgery and adjuvant treatment. However, only a few patients were able to finish the proposed treatments. Poor performance and high comorbidity index status might compromise the benefit of treatment aggressiveness and must be considered in therapeutic decision.

    Rodents use their whiskers to explore the environment, and the superior colliculus is part of the neural circuits that process this sensorimotor information. Cells in the intermediate layers of the superior colliculus integrate trigeminotectal afferents from trigeminal complex and corticotectal afferents from barrel cortex. Using histological methods in mice, we found that trigeminotectal and corticotectal synapses overlap somewhat as they innervate the lower and upper portions of the intermediate granular layer, respectively. Using electrophysiological recordings and optogenetics in anesthetized mice in vivo, we showed that, similar to rats, whisker deflections produce two successive responses that are driven by trigeminotectal and corticotectal afferents. We then employed in vivo and slice experiments to characterize the response properties of these afferents. In vivo, corticotectal responses triggered by electrical stimulation of the barrel cortex evoke activity in the superior colliculus that increases with stimulus intensity and depresses with increasing frequency. In slices from adult mice, optogenetic activation of channelrhodopsin-expressing trigeminotectal and corticotectal fibers revealed that cells in the intermediate layers receive more efficacious trigeminotectal, than corticotectal, synaptic inputs. Moreover, the efficacy of trigeminotectal inputs depresses more strongly with increasing frequency than that of corticotectal inputs. The intermediate layers of superior colliculus appear to be tuned to process strong but infrequent trigeminal inputs and weak but more persistent cortical inputs, which explains features of sensory responsiveness, such as the robust rapid sensory adaptation of whisker responses in the superior colliculus.

    Full Text Available Indexing is one of the most important methods of content representation where by assigning descriptors to the documents, their subject content are made known. Since index and indexing are remarkably significant in information retrieval, its quality and evaluation and provision of criteria and standards had always been the mainstay of researchers in this field. Given the fact that Indexing is a complex process, offering definitions, principles and methods could be step towards optimal use of the information. The present study, while offering a capsule definition of index, will investigate the indexing evaluation criteria and would follow it up with a definition of indexing. Finally a number of standards in the field of indexing are presented and would make its conclusions.

    Clobazam is a 1,5 benzodiazepine available in France since 1975, used in add-on with the other anticonvulsant drugs in the treatment of refractory epilepsies of child and adult and for the treatment of anxiety of adult. It is mainly metabolized in desmethylclobazam, or norclobazam, active metabolite, present in a concentration approximately eight times superior to that of the parent drug, but with an activity of the order of 20 to 40% of that of clobazam. Elimination half-life of clobazam is of 18 h while that of norclobazam is from 40 to 50 h. There is a large interindividual variability in the plasma concentrations. Furthermore, clobazam being prescribed in add-on with the other anticonvulsant drugs in resistant epilepsies, concentration-effect relationship is difficult to bring to light, since, in many studies, the patients who did not answer received the highest doses. Adverse reactions are moderated, appearing more often for the highest concentrations; also the phenomenon of tolerance seems more frequent in high concentrations. However, because of the kinetic interactions, a dosage of clobazam and norclobazam can be useful in certain cases. There is no validated therapeutic range, but the usual concentrations are in the range of 100-300 microg/L for the parent drug and about ten times more for the metabolite. The level of proof of the interest of the Therapeutic Drug Monitoring for this molecule is estimated in: rather useless.

    Objective The objective of this study was to determine the incidence of a "meniscoid" superior labrum. Materials and Methods This was a retrospective analysis of 582 magnetic resonance imaging examinations of shoulders. Of those 582 examinations, 110 were excluded, for a variety of reasons, and the final analysis therefore included 472 cases. Consensus readings were performed by three musculoskeletal radiologists using specific criteria to diagnose meniscoid labra. Results A meniscoid superior labrum was identified in 48 (10.2%) of the 472 cases evaluated. Arthroscopic proof was available in 21 cases (43.8%). In 10 (47.6%) of those 21 cases, the operative report did not include the mention a superior labral tear, thus suggesting the presence of a meniscoid labrum. In only one of those cases were there specific comments about a mobile superior labrum (i.e., meniscoid labrum). In the remaining 11 (52.4%), surgical correlation demonstrated superior labral tears. Conclusion A meniscoid superior labrum is not an infrequent finding. Depending upon assumptions and the requirement of surgical proof, the prevalence of a meniscoid superior labrum in this study was between 2.1% (surgically proven) and 4.8% (projected). However, superior labral tears are just as common and are often confused with meniscoid labra. PMID:27777474

    Full Text Available Background: The aim of this study was to determine the level of lipid peroxidation and tissue protein after superior mesenteric artery occlusion tissue damage. The effect of melatonin as anti oxidant and free radical scavenger in prevention of tissue damage, were also evaluated. Methods: Thity six young male Wisatr-Albino rats (weight: 80-120 gr, were divided equally in 6 group with different concentrations of melatonin (10,20,30 mg/kg treatment. Group 1was control, group 2 the sham that surgical process was applied until superior mesenteric artery dissection and received vehicle solution only in equally volume by intra muscular route. Group 3 was ischemia- reperfusion (I/R, group 4 was I/R plus melatonin 10 mg/kg, group 5 I/R plus melatonin 20 mg/kg and finally group 6 I/R plus melatonin 30 mg/kg. After laparatomy, a microvascular atraumatic clip was placed across the superior mesenteric artery under general anaesthesia and itbremoved after ischemia for 30 minutes. The first dose of melatonin was applied just beforereperfusion, second dose, after reperfusion and third dose on the second day .On third day rats were killed and their bowels were removed. The level of tissue melandialdehyde (MDA as index of lipid peroxidation and tissue protein was determined. Results: The level of tissue MDA were significantly lower in group 4, 5, 6 than group 3 (p0, 05. Conclusion: These results suggest that melatonin 10 mg/kg has antioxidant effect in prevention of inducing tissue damage during SMA occlusion in rat intestine.

    Full Text Available There has been an increase in the use of central venous catheters (CVCs in clinical practice. One of the most dangerous complications associated with their use is symptomatic or asymptomatic thrombosis (T, sometimes associated with superior vena cava (SVC syndrome, resulting from impaired venous drainage. The right heart clots can induce an increased risk of mortality due the potential pulmonary embolism (PE. We report a case of asymptomatic 83-year-old woman in whom the thrombosis was detected after an echocardiogram. Echocardiography demonstrated a cardiac mass, and the T was confirmed by (magnetic resonance imaging MRI. The clinical scenario, a high index of suspicion and routine use of echocardiogram in patients with CVC, can lead to a correct diagnosis, preventing dangerous complications.

    Sustained attention develops during childhood and has been linked to the right fronto-parietal cortices in functional imaging studies; however, less is known about its relation to white matter (WM) characteristics. Here we investigated whether the microstructure of the WM underlying and connecting the right fronto-parietal cortices was associated with sustained attention performance in a group of 76 typically developing children aged 7-13 years. Sustained attention was assessed using a rapid visual information processing paradigm. The two behavioral measures of interest were the sensitivity index d' and the coefficient of variation in reaction times (RTCV ). Diffusion-weighted imaging was performed. Mean fractional anisotropy (FA) was extracted from the WM underlying right dorsolateral prefrontal (DLPFC) and parietal cortex (PC), and the right superior longitudinal fasciculus (SLF), as well as equivalent anatomical regions-of-interest (ROIs) in the left hemisphere and mean global WM FA. When analyzed collectively, right hemisphere ROIs FA was significantly associated with d' independently of age. Follow-up analyses revealed that only FA of right SLF and the superior part of the right PC contributed significantly to this association. RTCV was significantly associated with right superior PC FA, but not with right SLF FA. Observed associations remained significant after controlling for FA of equivalent left hemisphere ROIs or global mean FA. In conclusion, better sustained attention performance was associated with higher FA of WM in regions connecting right frontal and parietal cortices. Further studies are needed to clarify to which extent these associations are driven by maturational processes, stable characteristics and/or experience.

    To evaluate the beneficial and adverse effects of breviscapine injection in combination with Western medicine on the treatment of patients with angina pectoris. The Cochrane Central Register of Controlled Trials, Medline, Science Citation Index, EMBASE, the China National Knowledge Infrastructure, the Wanfang Database, the Chongqing VIP Information Database and the China Biomedical Database were searched to identify randomized clinical trials (RCTs) that evaluated the effects of Western medicine compared to breviscapine injection plus Western medicine on angina pectoris patients. The included studies were analyzed using RevMan 5.1.0 software. The literature search yielded 460 studies, wherein 16 studies matched the selection criteria. The results showed that combined therapy using Breviscapine plus Western medicine was superior to Western medicine alone for improving angina pectoris symptoms (OR=3.77, 95% Cl: 2.76~5.15) and also resulted in increased electrocardiogram (ECG) improvement (OR=2.77, 95% Cl: 2.16~3.53). The current evidence suggests that Breviscapine plus Western medicine achieved a superior therapeutic effect compared to Western medicine alone.

  10. Exploring the word superiority effect using TVA

    DEFF Research Database (Denmark)

    Starrfelt, Randi

    Words are made of letters, and yet sometimes it is easier to identify a word than a single letter. This word superiority effect (WSE) has been observed when written stimuli are presented very briefly or degraded by visual noise. It is unclear, however, if this is due to a lower threshold...... for perception of words, or a higher speed of processing for words than letters. We have investigated the WSE using methods based on a Theory of Visual Attention. In an experiment using single stimuli (words or letters) presented centrally, we show that the classical WSE is specifically reflected in perceptual...... processing speed: words are simply processed faster than single letters. It is also clear from this experiment, that the word superiority effect can be observed at a large range of exposure durations, from the perceptual threshold to ceiling performance. Intriguingly, when multiple stimuli are presented...

    Objective: To observe the effect of acupuncture combined with massage on blood flow velocity of the vertebro-basilar artery in cervical spondylosis of vertebral arterial type (CSVAT) patients. Methods:In the present study, methods of evidence-based medicine, triple-centers, single-blindness, randomization and control were used. A total of 100 cases of CSVAT patients were randomized into acupuncture plus massage (acu-massage) group (n = 38), acupuncture group ( n = 32) and massage group ( n = 30). Acupoints used were Fengchi (风池 GB 20), cervical Jiaji (颈夹脊 EX-B 2), Baihui (百会 GV 20), and the methods of massage used were kneading-rolling, adhesion-separating and acupoint-digital pressing, topical digital pressing and rubbing, traction-extending and mild palm-rubbing. The treatment was conducted once daily, with 7 sessions being a therapeutic course and continuously for 2 courses. Changes of peak velocity (Vp), end-diastolic velocity (Vd), mean velocity (Vm) of blood flow of the vertebral artery (VA) and basilar artery (BA),etc were detected before and after the treatment by using transcranial Doppler (TCD) ultrasonography. Results: After the treatment, the abnormally low Vp of both VA and BA in acu-massage, acupuncture and massage groups, Vm of VA in acu-massage and acupuncture groups, Vm of BA in acu-massage and massage groups, and Vd of VA and BA in the 3 groups all increased significantly in comparison with their own pretreatment ( P < 0.05, 0.01 ), and the therapeutic effects of acu-massage group in the 3 indexes were significantly superior to those of acupuncture group and/or massage group (P < 0.05, 0.01 ). The abnormally increased Vp of VA in acu-massage and acupuncture groups, Vm of VA in the 3 groups, and Vd of VA in acu-massage and massage groups decreased obviously after the treatment in comparison with their own pretreatment (P <0.05, 0.01), and the therapeutic effects of acu-massage group were significantly superior to those of

    The superior biatrial septotomy approach consists of two semicircular right atrial and septal incisions joined at the superior end of the interatrial septum and extended across the dome of the left atrium, allowing exposure of the mitral valve by reflecting the ventricular side using stay sutures. From 1991 to 1993, 81 patients underwent mitral valve surgery by this technic. Mitral valve operation was combined with other cardiac procedures in 30 patients (37%) and was performed as a second operation in 21 patients (25.9%). Duration of cardiopulmonary bypass and aortic occlusion was not significantly different from that of patients operated via a conventional left atrial approach. The five hospital deaths (6.2%) were not related to this operative approach. Only 2 patients (3.3%) with preoperative in sinus rythm were discharged in atrial fibrillation after operation. In one patient (1.6%), atrioventricular block appeared at late follow-up. There were no cases of bleeding, atrioventricular nodal dysfunction or intra-atrial shunting related to the approach. This approach provides excellent exposure of the mitral valve even in unfavorable situations such as a small left atrium, dense adhesions from previous procedures or a previously implanted aortic prosthesis, without damage to various cardiac structures due to excessive traction. No retractor or vena cava repair are required. These data support a wide application of the superior biatrial septotomy approach in mitral valve surgery.

    2011-12-01

    Full Text Available Superior mesenteric artery syndrome is an entity generally caused by the loss of the intervening mesenteric fat pad, resulting in compression of the third portion of the duodenum by the superior mesenteric artery. This article reports the case of a patient with irremovable metastatic adenocarcinoma in the sigmoid colon, that evolved with intense vomiting. Intestinal transit was carried out, which showed important gastric dilation extended until the third portion of the duodenum, compatible with superior mesenteric artery syndrome. Considering the patient's nutritional condition, the medical team opted for the conservative treatment. Four months after the surgery and conservative measures, the patient did not present vomiting after eating, maintaining previous weight. Superior mesenteric artery syndrome is uncommon and can have unspecific symptoms. Thus, high suspicion is required for the appropriate clinical adjustment. A barium examination is required to make the diagnosis. The treatment can initially require gastric decompression and hydration, besides reversal of weight loss through adequate nutrition. Surgery should be adopted only in case of clinical treatment failure.A síndrome da artéria mesentérica superior é uma entidade clínica causada geralmente pela perda do tecido adiposo mesentérico, resultando na compressão da terceira porção do duodeno pela artéria mesentérica superior.

    Words are made of letters, and yet sometimes it is easier to identify a word than a single letter.

    2010-01-01

    BACKGROUND: Pancreatic adenocarcinoma remains the fourth leading cause of cancer-related death and is one of the most aggressive human tumors. At present, surgical resection is the only potentially curative treatment. Early neck division is inadequate when invasion of the superior mesenteric artery (SMA) is suspected or in cases of replaced or accessory right hepatic artery. Malignant periampullary tumors often invade retroperitoneal peripancreatic tissues and a positive resection margin is associated with a poor long-term survival. DATA SOURCES: English-language medical databases, PubMed, ELSEVIER and SPRINGERLINK, were searched for articles on"posterior approach pancreaticoduodenectomy","superior mesenteric artery ifrst approach", "retroperitoneal tissue","hanging maneuver", and related topics. RESULTS:The modiifcation allowed the surgeon to early identify the nonresectability of a replaced right hepatic artery if present, enabling complete dissection of the right side of the SMA and portal vein as well as complete excision of the retroportal pancreatic lamina. CONCLUSION: Pancreaticoduodenectomy with early retro-pancreatic dissection is a useful and safe technical variant, which is indicated for the improvement of the safety and curative effect of the procedure.

    The survival of patients with superior sulcus lung carcinoma and the effects of treatment were reviewed. From a prospective database of 4123 consecutive new patients with lung carcinoma, 131 (3.2%) cases of superior sulcus lung carcinoma were identified. Seventy-four patients were planned to receive radiation with palliative intent, 53 radical radiotherapy and one was observed only. The remaining three patients, with small-cell carcinoma, were treated with chemotherapy with or without radiotherapy. Of the 53 radically treated patients, nine were treated with pre-operative radiation prior to intended radical resection. Analysis was carried out on the effect on survival of performance status, nodal involvement, weight loss, vertebral body or rib involvement, treatment intent and radical combined modality treatment compared with radical radiation alone. The estimated median survival for the whole group was 7.6 months; for those treated radically it was 18.3 months, while for the palliatively treated patients it was 3.7 months. Radically treated patients with no initial nodal involvement had an estimated median survival of 22 months, while radically treated patients with nodal involvement had an estimated median survival of 8.4 months (P = 0.003). There were no statistically significant differences in survival between radically treated patients grouped according to initial weight loss, performance status, or vertebral body and rib involvement. Patients treated with pre-operative radiation did not survive significantly longer than patients treated with radiation alone, although the numbers are small. 33 refs., 2 tabs., 4 figs.

    Full Text Available We report here the results of a three year study on the zooplankton of Lago Paione Superiore, an acid sensitive lake above the tree line in the Italian Alps. The research was carried out within MOLAR, an EC-founded Project on “Measuring and Modeling the dynamic response of remote mountain lakes ecosystems to environmental change”. This study comes after a series of investigations on the effects of acidification, in which we documented the changes occurred with decreasing water pHs, by comparing the recent situation with that in the literature of the 40s, and reconstructed the beginning of anthropogenic disturbance through an analysis of the past cladocera assemblages archived in the lake sediments. A characteristic pattern in seasonal periodicity is a transition from a community dominated by small zooplankton (August to a community where the large particle-feeder Daphnia longispina dominates. This is a typical pattern observed in fishless, copepod-cladocera lakes. Regardless from which food is able to exploit, Daphnia population of Lago Paione Superiore is composed by well-fed organisms, visually rich in lipids, able to produce more than one generation/ year of parthenogenetic females at density levels which are rather high in an oligotrophic high mountain lake.

    Full Text Available Objective To investigate superior mesenteric artery flow measurement by Doppler ultrasonography as a means of characterizing inflammatory activity in Crohn's disease. Materials and Methods Forty patients were examined and divided into two groups – disease activity and remission – according to their Crohn's disease activity index score. Mean superior mesenteric artery flow volume was calculated for each group and correlated with Crohn's disease activity index score. Results The mean superior mesenteric artery flow volume was significantly greater in the patients with active disease (626 ml/min ± 236 × 376 ml/min ± 190; p = 0.001. As a cut off corresponding to 500 ml/min was utilized, the superior mesenteric artery flow volume demonstrated sensitivity of 83% and specificity of 82% for the diagnosis of Crohn's disease activity. Conclusion The present results suggest that patients with active Crohn's disease have increased superior mesenteric artery flow volume as compared with patients in remission. Superior mesenteric artery flow measurement had a good performance in the assessment of disease activity in this study sample.

    Objective:To compare the therapeutic effects of acupuncture of different acupoints in the treatment of spastic hemiplegia of apoplexy. Methods: Eighty stroke patients with spastic hemiplegia were evenly randomized into control group and treatment group. Forty cases of treatment group were given with acupuncture of Jiaji (夹脊 EX-B2) from T1 to L5, while forty cases of control group were treated with conventional acupoints as Jianyu (肩NFDA1 LI 15), Quchi (曲池 LI 11), Huantiao (环跳 GB 30), Zusanli (足三里 ST 36), Kunlun (昆仑 BL 60), etc. On the diseased side, once daily, with 10 sessions being one therapeutic course, and 3 courses all together. The modified Ashworth Scale (MAS) and neurological deficit grading scale (NDS) were used as the indexes to assess the therapeutic effects. Results: After treatment, the scores of NDS of both treatment and control groups reduced and the difference value between post- and pre-treatment of treatment group was significantly bigger than that of control group. MAS showed a similar tendency in both groups. Of the 40 cases in treatment and control groups, 6 and 1 were cured, 20 and 15 had marked improvement, 9 and 11 had improvement, 4 and 8 failed, 1 and 5 got worse, with the total effective rates being 87.5% and 67.5% respectively. The therapeutic effect of treatment group was significantly superior to that of control group (P<0.01). Conclusion: Acupuncture of Jiaji (EX-B2) is superior to acupuncture of conventional acupoints in alleviating the state of spastic hemiplegia of apoplexy.

    The market share between China Mobile and China Unicom has stabilized since 2002.It is found that China Mobile has the superiority in the competition, for example, the scissors movement between its revenue and cost indicates that it has a strong profit generating ability and there is enough room for it to reduce the price.The ratio between its price (marginal income) and marginal cost indicates that there is a very distant limit for it to reduce the price.Its demand is obviously flexible with the price, but it does not use the price weapon abundantly.The reason for the stabilization of the market is that China Mobile withdrew from the competition.

The dilated vein appeared as signal void tubular shadows on both T1 and T2 weighted images. The diameter of the enlarged vein was 3.5-6.0 mm. Extraocular muscle enlargement, orbital pathologies, enlarged carotid cavernous sinus etc were also revealed by MRI. Conclusion: The dilated SOV may be well demonstrated by MRI. The etiological diagnosis of enlarged SOV can be made in combination with the associated findings.

    On 4 July 1999, a severe convective windstorm, known as a derecho, caused extensive damage to forested regions along the United States/Canada border, west of Lake Superior. There were 665,000 acres of forest destroyed in the Boundary Waters Canoe Area Wilderness (BWCAW) in Minnesota and Quetico Provincial Park in Canada, with approximately 12.5 million trees blown down. This storm resulted in additional severe weather before and after the occurrence of the derecho, with continuous cloud-to-ground (CG) lightning occurring for more than 34 hours during its path across North America. At the time of the derecho the percentage of positive cloud-to-ground (+CG) lightning measured by the Canadian Lightning Detection Network (CLDN) was greater than 70% for more than three hours, with peak values reaching 97% positive CG lightning. Such high ratios of +CG are rare, and may be useful indicators of severe weather.

    2011-01-01

    Full Text Available Obstruction of blood flow in the superior vena cava (SVC results in symptoms and signs of SVC syndrome. SVC obstruction can be caused either by invasion or external compression of the SVC by contagious pathologic processes involving the right lung, lymph nodes, and other mediastinal structures, or by thrombosis of blood within the SVC. Occasionally, both mechanisms co-exist. We hereby report a case of a 28-year-old male, Saudi patient who was diagnosed with end-stage renal disease and was maintained on regular hemodiaysis via right jugular vein dual lumen catheter for ten months. Three years later, the patient presented with signs and symptoms suggestive of SVC obstruction that was successfully managed with SVC stenting.

    2015-01-01

    The authors present immediate and long-term results of treatment of 117 patients with superior thoracic outlet syndrome (STOS). There were different reasons for compression of neu- rovascular fascicle in outlet of the thorax. The costaclavicular syndrome was a reason in 48 patients, additional cervical ribs had 36 patients. Skalenus syndrome was noted in 26 cases, rudimentary cervical ribs or hypertrophy of cervical vertebrae C7 had 7 patients. Raynaud's syndrome took place in 19 cases. The required volume of diagnostic procedures and surgical treatment of STOS were determined according to the cause of the syndrome. Differentiated approach to the different forms of STOS was used in relation to dominant symptoms of the disease and reasons for compression of neurovascular fascicle. This allowed getting positive results in majority of patients (90,4%) in long- term period.

    1999-01-01

    In order to find the mechanism of superior clunial nerve (SCN) trauma, we dissected and revealed SCN from 12 corpses (24 sides). Combining 100 sides of SCN trauma, we inspected the course of SCN, the relation between SCN and it's neighbour tissues with the situation of SCN when being subjected to force. We found that the following special anatomic characteristics and mechanical elements such as the course of SCN, it's turning angles, the bony fibrous tube at the iliac crest, the posterior layer of the lumbodorsal fascia and SCN neighbour adipose tissue, are the causes of external force inducing SCN trauma. The anatomic revealment is the guidance of SCN trauma treatment with edged needle.

    Herman, G T; Davidi, R; Censor, Y

    2012-01-01

    Purpose: To describe and mathematically validate the superiorization methodology, which is a recently-developed heuristic approach to optimization, and to discuss its applicability to medical physics problem formulations that specify the desired solution (of physically given or otherwise obtained constraints) by an optimization criterion. Methods: The underlying idea is that many iterative algorithms for finding such a solution are perturbation resilient in the sense that, even if certain kinds of changes are made at the end of each iterative step, the algorithm still produces a constraints-compatible solution. This property is exploited by using permitted changes to steer the algorithm to a solution that is not only constraints-compatible, but is also desirable according to a specified optimization criterion. The approach is very general, it is applicable to many iterative procedures and optimization criteria used in medical physics. Results: The main practical contribution is a procedure for automatically p...

  16. Superior calcium homeostasis of extraocular muscles.

    Zeiger, Ulrike; Mitchell, Claire H; Khurana, Tejvir S

    2010-11-01

    Extraocular muscles (EOMs) are a unique group of skeletal muscles with unusual physiological properties such as being able to undergo rapid twitch contractions over extended periods and escape damage in the presence of excess intracellular calcium (Ca(2+)) in Duchenne's muscular dystrophy (DMD). Enhanced Ca(2+) buffering has been proposed as a contributory mechanism to explain these properties; however, the mechanisms are not well understood. We investigated mechanisms modulating Ca(2+) levels in EOM and tibialis anterior (TA) limb muscles. Using Fura-2 based ratiometric Ca(2+) imaging of primary myotubes we found that EOM myotubes reduced elevated Ca(2+) ˜2-fold faster than TA myotubes, demonstrating more efficient Ca(2+) buffering. Quantitative PCR (qPCR) and western blotting revealed higher expression of key components of the Ca(2+) regulation system in EOM, such as the cardiac/slow isoforms sarcoplasmic Ca(2+)-ATPase 2 (Serca2) and calsequestrin 2 (Casq2). Interestingly EOM expressed monomeric rather than multimeric forms of phospholamban (Pln), which was phosphorylated at threonine 17 (Thr17) but not at the serine 16 (Ser16) residue. EOM Pln remained monomeric and unphosphorylated at Ser16 despite protein kinase A (PKA) treatment, suggesting differential signalling and modulation cascades involving Pln-mediated Ca(2+) regulation in EOM. Increased expression of Ca(2+)/SR mRNA, proteins, differential post-translational modification of Pln and superior Ca(2+) buffering is consistent with the improved ability of EOM to handle elevated intracellular Ca(2+) levels. These characteristics provide mechanistic insight for the potential role of superior Ca(2+) buffering in the unusual physiology of EOM and their sparing in DMD.

  17. The management of superior sulcus tumors

    2001-09-01

    Superior sulcus tumors are a rare type of lung cancer arising in the apex of the lung above the sulcus and cause specific symptoms and signs depending on the location and whether the tumor extends into the surrounding structures. Because of the closeness of critical structures to the tumor (e.g., the subclavian artery for anterior lesions, the brachial plexus for lesions in the middle location, and the sympathetic stellate ganglion causing Horner's syndrome [Pancoast's tumor], the vertebral bodies, nerve foramen, and spinal cord for posterior lesions), superior sulcus tumors were often considered marginally respectable or unresectable. Therefore, for many years, preoperative radiation therapy was considered routine treatment for those tumors. However, with the evolution in our understanding of these tumors and modern imaging techniques such as computerized tomography (CT) and magnetic resonant imaging (MRI) and surgical techniques, there is now considerable debate about the roles and timing of surgical resection, radiation therapy, and chemotherapy in the treatment of patients with these tumors. If mediastinoscopy reveals microscopic mediastinal lymph node involvement, the patient can be treated with preoperative concurrent chemoradiotherapy followed by surgery. If there was a gross mediastinal lymph node involvement (N2) on CT, N3 or T4 lesions, the patient can be treated with concurrent chemoradiotherapy with a curative intent; the outcome of such treatment appears to be better than that of sequential chemotherapy followed by radiation therapy. Whenever possible, without compromising the patient's quality of life, surgery should be considered to improve outcome. (author)

    With its long duration and high gain antenna (HGA) feed thermal constraint; the NASA Solar-TErestrial RElations Observatory (STEREO) solar conjunction mission phase is quite unique to deep space operations. Originally designed for a two year heliocentric orbit mission to primarily study coronal mass ejection propagation, after 8 years of continuous science data collection, the twin STEREO observatories entered the solar conjunction mission phase, for which they were not designed. Nine months before entering conjunction, an unforeseen thermal constraint threatened to stop daily communications and science data collection for 15months. With a 3.5 month long communication blackout from the superior solar conjunction, without ground commands, each observatory will reset every 3 days, resulting in 35 system resets at an Earth range of 2 AU. As the observatories will be conjoined for the first time in 8 years, a unique opportunity for calibrating the same instruments on identical spacecraft will occur. As each observatory has lost redundancy, and with only a limited fidelity hardware simulator, how can the new observatory configuration be adequately and safely tested on each spacecraft? Without ground commands, how would a 3-axis stabilized spacecraft safely manage the ever accumulating system momentum without using propellant for thrusters? Could science data still be collected for the duration of the solar conjunction mission phase? Would the observatories survive? In its second extended mission, operational resources were limited at best. This paper discusses the solutions to the STEREO superior solar conjunction operational challenges, science data impact, testing, mission operations, results, and lessons learned while implementing.

    2016-05-01

    Full Text Available Aim: to evaluate potential efficacy of a new therapeutic approach in posttraumatic stress disorder in comparison with eye movement desensitization and reprocessing (EMDR, a standard treatment approach and controls. Methods: the study was designed using a randomized controlled trial methodology. Participants were recruited from military servicemen aged between 25 to 50 years who were admitting hospitals of Bushehr, Iran, with the final diagnosis of PTSD. Finally 33 male patients were devided into three subgroups: G1: EMDR; G2: REM Desensitization; and group 3: controls who received no therapy. Mississippi Scale for Posttraumatic Stress Disorder, Pittsburgh Sleep Quality Index (PSQI and a 37 item death anxiety questionnaire were used for measures. Results: multiple comparisons showed that intrusive thoughts were significantly more likely to improve with REM Desensitization versus EMDR (P=0.03, while depression was more responsive to EMDR (p=0.03. Among the Pittsburgh scale for the quality of sleep items, sleep quality (p=0.02, sleep duration (p=0.001, and total sleep quality score (p=0.002 were significantly more likely to improve in the REM Desensitization group. Change in the absolute death anxiety scores was not different between subgroups excepting EMDR versus control group (p=0.05. Conclusion: REM, desensitization, the new therapeutic approach to PTSD is a highly effective strategy, even more than EMDR, the standard treatment, in most of the evaluated subjects, with special emphasis on sleep symptoms, and also in the management of intrusive thoughts. Depression is the only factor in which, REM Desensitization was significantly less likely to represent a superior therapeutic effect than EMDR. Key words: post traumatic stress disorder (PTSD, eye movement desensitization and reprocessing, new treatment.

  20. Myostatin as a therapeutic target in Amyotrophic lateral sclerosis.

    Walsh, Frank S; Rutkowski, Julia Lynn

    2012-11-01

    Amyotrophic Lateral Sclerosis is a devastating neurological disease that is inevitably fatal after 3-5years duration. Treatment options are minimal and as such new therapeutic modalities are required. In this review, we discuss the role of the myostatin pathway as a modulator of skeletal muscle mass and therapeutic approaches using biological based therapies. Both monoclonal antibodies to myostatin and a soluble receptor decoy to its high affinity receptor have been used in clinical trials of neuromuscular diseases and while there have been efficacy signals with the latter approach there have also been safety issues. Our approach is to target the high affinity receptor-binding site on myostatin and to develop a next generation set of therapeutic reagents built on a novel protein scaffold. This is the natural single domain VNAR found in sharks which is extremely versatile and has the ability to develop products with superior properties compared to existing therapeutics.

  1. A Multifactorial Mechanism in the Superior Antimalarial Activity of α-C-GalCer

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available We have previously shown that the C-glycoside analog of α-galactosylceramide (α-GalCer, α-C-GalCer, displays a superior inhibitory activity against the liver stages of the rodent malaria parasite Plasmodium yoelii than its parental glycolipid, α-GalCer. In this study, we demonstrate that NK cells, as well as IL-12, are a key contributor for the superior activity displayed by α-C-GalCer. Surprisingly, the diminished production of Th2 cytokines, including IL-4, by α-C-GalCer has no affect on its superior therapeutic activity relative to α-GalCer. Finally, we show that the in vivo administration of α-C-GalCer induces prolonged maturation of dendritic cells (DCs, as well as an enhanced proliferative response of mouse invariant Vα14 (Vα14i NKT cells, both of which may also contribute to some degree to the superior activity of α-C-GalCer in vivo.

    To determine glycemic, insulinemic, and satiety indices of 3 types of kefir. This study was divided into 3 phases. In phase 1, 50 g of available carbohydrate from low-fat strawberry kefir or orange kefir was tested, and in phase 2, low-fat plain kefir containing 25 g of available carbohydrates was tested for glycemic index (GI), in both cases compared with an equivalent amount of glucose. In phase 3, 1000-kJ portions of all 3 types of kefirs were compared with white bread with the same energy content to determine the insulinemic index (II) and satiety index (SI) of all 3 kefirs. In all phases, a single-meal, randomized crossover design was performed in which the test meals were given to healthy adults, 5 men and 5 women. The total incremental plasma glucose area under the curve (iAUC) for strawberry, orange, and plain kefirs was significantly lower compared with the respective high-GI control food, which was glucose solution. However, the IIs and SIs of kefir did not differ significantly from the white bread. Kefir is a low- to moderate-GI food; however, its II was high. Although kefir had higher water content, the SI of kefir was not significantly different from white bread.

    2013-01-01

    Full Text Available Lymphedema is a disorder of the lymphatic vascular system characterized by impaired lymphatic return and swelling of the extremities. Lymphedema is divided into primary and secondary forms based on the underlying etiology. Despite substantial advances in both surgical and conservative techniques, therapeutic options for the management of lymphedema are limited. Although rarely lethal, lymphedema is a disfiguring and disabling condition with an associated decrease in the quality of life. The recent impressive expansion of knowledge on the molecular mechanisms governing lymphangiogenesis provides new possibilities for the treatment of lymphedema. This review highlights the lymphatic biology, the pathophysiology of lymphedema, and the therapeutic lymphangiogenesis using hepatocyte growth factor.

    Full Text Available Pancreatic pseudocyst develops in both acute and chronic pancreatitis. It is an entity likely to either remain asymptomatic or develop devastating complications. Despite being diagnosed easily, treatment exercise is still at crossroads whether in the form of internal or external drainage or endoscopic, laparoscopic, or open intervention with a good radiological guidance. The therapeutic dilemma whether to treat a patient with a pancreatic pseudocyst, as well as when and with what technique, is a difficult one. This paper is intended to get information about diagnostic and therapeutic exercises most appropriate for acute and chronic pancreatic pseudocyst.

    The eccentric connectivity index, proposed by Sharma, Goswami and Madan, has been employed successfully for the development of numerous mathematical models for the prediction of biological activities of diverse nature. We now report mathematical properties of the eccentric connectivity index. We establish various lower and upper bounds for the eccentric connectivity index in terms of other graph invariants including the number of vertices, the number of edges, the degree distance and the first Zagreb index. We determine the n-vertex trees of diameter with the minimum eccentric connectivity index, and the n-vertex trees of pendent vertices, with the maximum eccentric connectivity index. We also determine the n-vertex trees with respectively the minimum, second-minimum and third-minimum, and the maximum, second-maximum and third-maximum eccentric connectivity indices for

  7. NEW CONCEPTS IN INDEXING.

    Science.gov (United States)

    SHANK, R

    1965-07-01

    Recent trends in indexing emphasize mechanical, not intellectual, developments. Mechanized operations have produced indexes in depth (1) of information on limited areas of science or (2) utilizing limited parameters for analysis. These indexes may include only citations or both useful data and citations of source literature. Both keyword-in-context and citation indexing seem to be passing the test of the marketplace. Mechanical equipment has also been successfully used to manipulate EAM cards for production of index copy. Information centers are increasingly being used as control devices in narrowly defined subject areas. Authors meet growing pressures to participate in information control work by preparing abstracts of their own articles. Mechanized image systems persist, although large systems are scarce and the many small systems may bring only limited relief for information control and retrieval problems. Experimentation and limited development continue on theory and technique of automatic indexing and abstracting.

    Gabbard, Glen O; Westen, Drew

    2003-08-01

    Like other core psychoanalytic constructs, the theory of therapeutic action is currently in flux, as theorists of differing persuasions propose different mechanisms. In this article, the authors attempt to integrate developments within and without psychoanalysis to provide a working model of the multifaceted processes involved in producing change in psychoanalysis and psychoanalytic psychotherapy. A theory of therapeutic action must describe both what changes (the aims of treatment) and what strategies are likely to be useful in facilitating those changes (technique). The authors believe that single-mechanism theories of therapeutic action, no matter how complex, are unlikely to prove useful at this point because of the variety of targets of change and the variety of methods useful in effecting change in those targets (such as techniques aimed at altering different kinds of conscious and unconscious processes). Interventions that facilitate change may be classified into one of three categories: those that foster insight, those that make use of various mutative aspects of the treatment relationship and a variety of secondary strategies that can be of tremendous importance. They propose that, in all forms of psychoanalytic treatment, we would be more accurate to speak of the therapeutic actions, rather than action.

    Kilcoyne, Michelle; Joshi, Lokesh

    2007-07-01

    Awareness of the importance of carbohydrates in living systems and medicine is growing due to the increasing understanding of their biological and pharmacological relevance. Carbohydrates are ubiquitous and perform a wide array of biological roles. Carbohydrate-based or -modified therapeutics are used extensively in cardiovascular and hematological treatments ranging from inflammatory diseases and anti-thrombotic treatments to wound healing. Heparin is a well-known and widely used example of a carbohydrate-based drug but will not be discussed as it has been extensively reviewed. We will detail carbohydrate-based and -modified therapeutics, both those that are currently marketed or in various stages of clinical trials and those that are potential therapeutics based on promising preclinical investigations. Carbohydrate-based therapeutics include polysaccharide and oligosaccharide anti-inflammatory, anti-coagulant and anti-thrombotic agents from natural and synthetic sources, some as an alternative to heparin and others which were designed based on known structure-functional relationships. Some of these compounds have multiple biological effects, showing anti-adhesive, anti-HIV and anti-arthrithic activities. Small molecules, derivatives or mimetics of complement inhibitors, are detailed for use in limiting ischemia/ reperfusion injuries. Monosaccharides, both natural and synthetic, have been investigated for their in vivo anti-inflammatory and cardioprotective properties. Modification by glycosylation of natural products, or glycosylation-mimicking modification, has a significant effect on the parent molecule including increased plasma half-life and refining or increasing desired functions. It is hoped that this review will highlight the vast therapeutic potential of these natural bioactive molecules.

    A mathematical model for research on the refractive index profile (RIP) of multistep ion exchange processes (IEPs) of gradient refractive index rod lenses (GRINs) is established by the different initial condition and boundary condition, based on the Fickian diffusion equation. GRIN rod lenses have been fabricated using the three-step IEPs. Research results indicate that the experimental deviations of refractive index (DRI) are in good agreement with the theoretical data. The DRI of three-step IEPs is superior to the one- and two-step IEPs and smaller than 10(-5).

    2014-10-01

    Full Text Available According to the Resource-Based View, the nature of the resources, competences and knowledge accumulated by firms are the major causes of variation in business performance. In view of the importance attributed to intangible assets, the purpose of the present study was to investigate whether innovative firms with superior and sustained performance and firms without superior and sustained performance differ with regard to investments in intangible assets. The sample consisted of 137 firms listed on the Brazilian stock exchange from 2007 to 2010 and belonging to innovative sectors according to the Brazilian Innovation Index. Only 51 firms with profitability above the sector average during the entire study period (four years met the criterion of superior and sustained performance. Thus, using return on assets as a proxy for performance, investments in intangibles were found to be greater in firms without superior and sustained performance, particularly with regard to the categories intellectual property assets (the predominant category and infrastructure assets. Based on the lack of evidence for a significant correlation between corporate performance and investment in intangible assets, our initial hypothesis that a positive relation exists between the composition of investments in intangible assets and the performance of innovative firms could not be confirmed.

  2. Lake Superior Coastal Wetland Fish Assemblages and ...

    Science.gov (United States)

    The role of the coastal margin and the watershed context in defining the ecology of even very large lakes is increasingly being recognized and examined. Coastal wetlands are both important contributors to the biodiversity and productivity of large lakes and important mediators of the lake-basin connection. We explored wetland-watershed connections and their relationship to wetland function and condition using data collected from 37 Lake Superior wetlands spanning a substantial geographic and geomorphic gradient. While none of these wetlands are particularly disturbed, there were nevertheless clear relationships between watershed landuse and wetland habitat and biota, and these varied consistently across wetland type categories that reflected the strength of connection to the watershed. For example, water clarity and vegetation structure complexity declined with decreasing percent natural land cover, and these effects were strongest in riverine wetlands (having generally large watersheds and tributary-dominated hydrology) and weakest in lagoon wetlands (having generally small watersheds and lake-dominate hydrology). Fish abundance and species richness both increased with decreasing percent natural land cover while species diversity decreased, and again the effect was strongest in riverine wetlands. Lagoonal wetlands, which lack any substantial tributary, consistently harbored the fewest species of fish and a composition different from the more watershed-lin

PDAA is a rare but life-threatening condition. The widely varying symptomatology may lead to a delay in diagnosis and treatment. Patients with atypical symptoms, such as vague abdominal pain, recurrent dizziness or syncope, may actually suffer from a sentinel bleeding of the vascular malformation. Radiological imaging, especially selective angiography, may provide a diagnostic as well as a therapeutic tool in these patients.

    To analyze the superiorities of acupoint catgut-embedding therapy, discuss its law of clinical application and provide scientific decision-making for clinical treatment. Literatures on acupoint catgut-embedding therapy in the recent 40 years were selected, input, examined and verified, picked up and analyzed by establishing database with the modern computer technology. (1) One thousand and seventy-five literatures were input. It shows that the acupoint catgut-embedding therapy has an extensive application in all departments, especially in the internal department, accounting for 48.54% (50/103) of the total disease category. It has the most extensive application on treatment of epigastric pain, with the frequency of 102 times, and obesity of 74 times. The next is surgery, accounting for 14.56% (15/103). The major application is on low back pain and leg pain with the frequency of 79 times. Psoriasis, with the frequency of 30 times, holds the major application in dermatological department. And blepharoplasty, with the frequency of 30 times, gains the most application in department of ophthalmology and otorhinolaryngology. (2) In the included literatures, selection of adjacent acupoints and distal acupoints are held as the major method of acupoint selection. The adjusted lumbar puncture needle is taken as the major tool for the acupoint catgut-embedding therapy. And catguts of different sizes are adopted for the operation. (3) Analysis of the therapeutic effect shows that acupoint catgut-embedding therapy has obvious effect in all departments, especially in surgery and dermatology, with the total effective rate over 90%. Epigastric pain, obesity, epilepsy, asthma, abdominal pain, facial paralysis and constipation of the internal medicine, low back pain and leg pain of the surgical department, psoriasis of the dermatological department and blepharoplasty of the department of ophthalmology and otorhinolaryngology are considered as the dominant diseases for acupoint

  12. Eccentric connectivity index

    2011-01-01

    The eccentric connectivity index $\\xi^c$ is a novel distance--based molecular structure descriptor that was recently used for mathematical modeling of biological activities of diverse nature. It is defined as $\\xi^c (G) = \\sum_{v \\in V (G)} deg (v) \\cdot \\epsilon (v)$\\,, where $deg (v)$ and $\\epsilon (v)$ denote the vertex degree and eccentricity of $v$\\,, respectively. We survey some mathematical properties of this index and furthermore support the use of eccentric connectivity index as topological structure descriptor. We present the extremal trees and unicyclic graphs with maximum and minimum eccentric connectivity index subject to the certain graph constraints. Sharp lower and asymptotic upper bound for all graphs are given and various connections with other important graph invariants are established. In addition, we present explicit formulae for the values of eccentric connectivity index for several families of composite graphs and designed a linear algorithm for calculating the eccentric connectivity in...

  13. Bounded hybrid superiority in an avian hybrid zone: effects of mate, diet, and habitat choice.

    Science.gov (United States)

    Good, T P; Ellis, J C; Annett, C A; Pierotti, R

    2000-10-01

    There has been considerable debate in the study of hybrid zones as to whether hybrids may be superior to parental types within the area of contact (bounded hybrid superiority). In birds, naturally occurring hybridization is relatively common, and hybridization within this group always involves mate choice. If hybrids are superior, females choosing heterospecific mates should be expected to show higher fitness under the conditions prevalent in the hybrid zone. Hybrid superiority under these circumstances would reduce reinforcement and thereby help to maintain the hybrid zone. To examine this issue, we studied reproductive performances of hybrids and parental species of gulls (Larus occidentalis and Larus glaucescens) at two colonies within a linear hybrid zone along the west coast of the United States. This hybrid zone contains predominantly gulls of intermediate phenotype. Previous studies indicated that hybrids were superior to one or both parental types, but provided no data on possible mechanisms that underlie this hybrid superiority. Using a hybrid index designed specifically for these species, we identified to phenotype more than 300 individuals associated with nests, including both individual males and females within 73 pairs in the central portion of the hybrid zone and 74 pairs in the northern portion of the hybrid zone. There was little evidence of assortative mating, and what little there was resulted solely because of pairings within intergrades. In the central hybrid zone, females paired with hybrid males produced larger clutches and hatched and fledged more chicks compared with females paired to western gull males. This was a result of heavy predation on eggs in sand habitat, where male western gulls established territories. In contrast, many hybrid males established territories in vegetated cover that was less vulnerable to predation. In the northern part of the hybrid zone, clutch size did not differ among pair categories, however, there were

    Two dimensional (2D) materials with a finite band gap and high carrier mobility are sought after materials from both fundamental and technological perspectives. In this paper, we present the results based on the particle swarm optimization method and density functional theory which predict three geometrically different phases of the carbon phosphide (CP) monolayer consisting of sp2 hybridized C atoms and sp3 hybridized P atoms in hexagonal networks. Two of the phases, referred to as α-CP and β-CP with puckered or buckled surfaces are semiconducting with highly anisotropic electronic and mechanical properties. More remarkably, they have the lightest electrons and holes among the known 2D semiconductors, yielding superior carrier mobility. The γ-CP has a distorted hexagonal network and exhibits a semi-metallic behavior with Dirac cones. These theoretical findings suggest that the binary CP monolayer is a yet unexplored 2D material holding great promise for applications in high-performance electronics and optoelectronics.Two dimensional (2D) materials with a finite band gap and high carrier mobility are sought after materials from both fundamental and technological perspectives.

    Industrial facilities participating in the U.S. Department of Energy’s (US DOE) Superior Energy Performance (SEP) program are finding that it provides them with significant business value. This value starts with the implementation of ISO 50001-Energy management system standard, which provides an internationally-relevant framework for integration of energy management into an organization’s business processes. The resulting structure emphasizes effective use of available data and supports continual improvement of energy performance. International relevance is particularly important for companies with a global presence or trading interests, providing them with access to supporting ISO standards and a growing body of certified companies representing the collective knowledge of communities of practice. This paper examines the business value of SEP, a voluntary program that builds on ISO 50001, inviting industry to demonstrate an even greater commitment through third-party verification of energy performance improvement to a specified level of achievement. Information from 28 facilities that have already achieved SEP certification will illustrate key findings concerning both the value and the challenges from SEP/ISO 50001 implementation. These include the facilities’ experience with implementation, internal and external value of third-party verification of energy performance improvement; attractive payback periods and the importance of SEP tools and guidance. US DOE is working to bring the program to scale, including the Enterprise-Wide Accelerator (SEP for multiple facilities in a company), the Ratepayer-Funded Program Accelerator (supporting tools for utilities and program administrators to include SEP in their program offerings), and expansion of the program to other sectors and industry supply chains.

    2014-01-01

    Full Text Available Superior mesenteric artery syndrome is a rare condition that causes a proximal small intestinal obstruction due to contraction of the angle between the superior mesenteric artery and the aorta. Scoliosis surgery is one of the 15 reasons for superior mesenteric artery syndrome, which can present with acute or chronic manifestations. Although conservative treatment is usually possible, surgical treatment is required in certain cases that cannot be treated using conservative methods. In this paper, we describe a patient who developed superior mesenteric artery syndrome after scoliosis surgery and was treated with duodenojejunostomy due to failure and complications of conservative treatment.

    Full Text Available Superior vena cava syndrome is a common presentation of bronchogenic carcinoma. The mechanism of obstruction is by compression of superior vena cava by the bronchogenic tumor itself or enlarged mediastinal lymph nodes. However obstruction due to intravascular thrombosis is extremely uncommon. Here, we report a rare case of a 65-year-old male smoker who presented with superior vena cava syndrome and bilateral pleural and pericardial effusion with thrombotic occlusion of the superior vena cava in adenocarcinoma of the lung. He was given chemotherapy with carboplatin and gemcitabine with anticoagulant therapy.

    We revise the sequences of SUSY for a cyclic adiabatic evolution governed by the supersymmetric quantum mechanical Hamiltonian. The condition (supersymmetric adiabatic evolution) under which the supersymmetric reductions of Berry (nondegenerated case) or Wilczek-Zee (degenerated case) phases of superpartners are taking place is pointed out. The analogue of Witten index (supersymmetric Berry index) is determined. As the examples of suggested concept of supersymmetric adiabatic evolution the Holomorphic quantum mechanics on complex plane and Meromorphic quantum mechanics on Riemann surface are considered. The supersymmetric Berry indexes for the models are calculated.

    2002-07-01

    It has been suggested that foods with a high glycemic index are detrimental to health and that healthy people should be told to avoid these foods. This paper takes the position that not enough valid scientific data are available to launch a public health campaign to disseminate such a recommendation. This paper explores the glycemic index and its validity and discusses the effect of postprandial glucose and insulin responses on food intake, obesity, type 1 diabetes, and cardiovascular disease. Presented herein are the reasons why it is premature to recommend that the general population avoid foods with a high glycemic index.

    Restrepo Valencia, C A; Buritica Barragán, C M; Arango, A

    2010-01-01

    We report four patients with chronic kidney disease undergoing haemodialysis therapy, which had exhausted conventional venous access (internal jugular, subclavian) and non-conventional access (axillary, innominate) in the upper hemithorax for haemodialysis. This was primarily due to thrombosis of these veins caused by previous catheterisation. These patients did not qualify for peritoneal dialysis. Using the technique recommended by Archundia et al., 4 indwelling catheters were implanted directly in the superior vena cava in each of the patients with subsequent subcutaneous tunneling. The catheters operated correctly and are currently permeable after being used for an average of 19 months.

    Shen, Chen; Xie, Yangbo; Li, Junfei; Cummer, Steven A.; Jing, Yun

    2016-05-01

    We present a design of acoustic metasurfaces yielding asymmetric transmission within a certain frequency band. The design consists of a layer of gradient-index metasurface and a layer of low refractive index metasurface. Incident waves are controlled in a wave vector dependent manner to create strong asymmetric transmission. Numerical simulations show that the approach provides high transmission contrast between the two incident directions within the designed frequency band. This is further verified by experiments. Compared to previous designs, the proposed approach yields a compact and planar device. Our design may find applications in various scenarios such as noise control and therapeutic ultrasound.

  12. Frankincense--therapeutic properties.

    Science.gov (United States)

    Al-Yasiry, Ali Ridha Mustafa; Kiczorowska, Bożena

    2016-01-04

    Recently, increasing interest in natural dietary and therapeutic preparations used as dietary supplements has been observed. One of them is frankincense. This traditional medicine of the East is believed to have anti-inflammatory, expectorant, antiseptic, and even anxiolytic and anti-neurotic effects. The present study aims to verify the reported therapeutic properties of Boswellia resin and describe its chemical composition based on available scientific studies. The main component of frankincense is oil (60%). It contains mono- (13%) and diterpenes (40%) as well as ethyl acetate (21.4%), octyl acetate (13.4%) and methylanisole (7.6%). The highest biological activity among terpenes is characteristic of 11-keto-ß-acetyl-beta-boswellic acid, acetyl-11-keto-ß-boswellic acid and acetyl-α-boswellic acid. Contemporary studies have shown that resin indeed has an analgesic, tranquilising and anti-bacterial effects. From the point of view of therapeutic properties, extracts from Boswellia serrata and Boswellia carterii are reported to be particularly useful. They reduce inflammatory conditions in the course of rheumatism by inhibiting leukocyte elastase and degrading glycosaminoglycans. Boswellia preparations inhibit 5-lipoxygenase and prevent the release of leukotrienes, thus having an anti-inflammatory effect in ulcerative colitis, irritable bowel syndrome, bronchitis and sinusitis. Inhalation and consumption of Boswellia olibanum reduces the risk of asthma. In addition, boswellic acids have an antiproliferative effect on tumours. They inhibit proliferation of tumour cells of the leukaemia and glioblastoma subset. They have an anti-tumour effect since they inhibit topoisomerase I and II-alpha and stimulate programmed cell death (apoptosis).

    The therapeutic patient education is an absolute necessity in the management of chronic diseases including diabetes. This discipline promotes personal autonomy to live optimally, to achieve personal and professional projects, despite the constraints of the disease and treatments. The DAWN2 study demonstrates the systemic effects of this disease that goes beyond simple glycemic control. The biopsychosocial dimension needs to be better explored. Other assessment tools should be used to better manage these patients. Exploring the health literacy and numeracy are other tools that can explore the problems for socially disadvantaged patients. The main goal is development of patient capabilities and his environment for the development of the human person.

    Therapeutic objectives for patients with atherogenic dyslipidemia are achieved by improving patient compliance and adherence. Clinical practice guidelines address the importance of treatment compliance for achieving objectives. The combination of a fixed dose of pravastatin and fenofibrate increases the adherence by simplifying the drug regimen and reducing the number of daily doses. The good tolerance, the cost of the combination and the possibility of adjusting the administration to the patient's lifestyle helps achieve the objectives for these patients with high cardiovascular risk.

    Cellulite is a condition that affects the vast majority of women. Although it is of no danger to one's overall health, cellulite can be psychosocially debilitating. Consequently, much research has been devoted to understanding cellulite and its etiopathogenesis. With additional insights into the underlying causes of its clinical presentation, therapeutic modalities have been developed that offer hope to cellulite sufferers. This review examines evidence for topical treatments, noninvasive energy-based devices, and recently developed minimally invasive interventions that may finally provide a solution. ©2015 Frontline Medical Communications.

    Singla, Animesh A; Singla, Apresh A

    2015-11-12

    The introduction of seatbelts to legislation has dramatically reduced mortality and morbidity from motor vehicle accidents. However, overtime evidence has emerged of 'seatbelt syndrome' (SBS), particularly in the paediatric population. The report describes the diagnosis and management of this rare injury in a 12-year-old boy who sustained a chance lumbar fracture and mesenteric tear resulting in small bowel obstruction. His stay was subsequently complicated by superior mesenteric artery (SMA) syndrome. This is the first documented case of SBS with SMA syndrome. High index of suspicion and continuity of care, particularly in the setting of a 'seatbelt sign', is paramount to timely diagnosis and management.

    Full Text Available Abstract Introduction Ischemic bowel disease comprises both mesenteric ischemia and colonic ischemia. Mesenteric ischemia can be divided into acute and chronic ischemia. These are two separate entities, each with their specific clinical presentation and diagnostic and therapeutic modalities. However, diagnosis may be difficult due to the vague symptomatology and subtle signs. Case presentation We report the case of a 68-year-old Caucasian woman who presented with abdominal discomfort, anorexia, melena and fever. A physical examination revealed left lower quadrant tenderness and an irregular pulse. Computed tomography of her abdomen as well as computed tomography enterography, enteroscopy, angiography and small bowel enteroclysis demonstrated an ischemic jejunal segment caused by occlusion of a branch of the superior mesenteric artery. The ischemic segment was resected and an end-to-end anastomosis was performed. The diagnosis of segmental small bowel ischemia was confirmed by histopathological study. Conclusion Mesenteric ischemia is a pathology well-known by surgeons, gastroenterologists and radiologists. Acute and chronic mesenteric ischemia are two separate entities with their own specific clinical presentation, radiological signs and therapeutic modalities. We present the case of a patient with symptoms and signs of chronic mesenteric ischemia despite an acute etiology. To the best of our knowledge, this is the first report presenting a case of acute mesenteric ischemia with segmental superior mesenteric artery occlusion.

    The purpose of these studies was to test the hypothesis that a selected polypharmacological approach for treating the prostanoid-mediated component of inflammatory diseases would produce a therapeutic effect superior to global inhibition of prostaglandin (PG) biosynthesis by aspirin-like drugs. The compound studied was AGN 211377, which had been previously shown to produce a superior effect on cytokine release from human macrophages compared with cyclooxygenase (COX) inhibitors. AGN 211377 antagonizes prostanoid prostaglandin D2 (DP)1, DP2, prostaglandin E2 (EP)1, EP4, prostaglandin F2α, and thromboxane A2 receptors but not anti-inflammatory EP2, prostaglandin I2, or EP3 receptors. Established rodent models of ocular inflammatory diseases were used to determine therapeutic effects in living animals. The drugs were administered systemically after predetermination of their blood levels to ensure bioavailability at an appropriate dose level. Whereas compounds selective for a single prostanoid receptor typically exhibited modest but statistically significant inhibition, AGN 211377 profoundly inhibited S-antigen-induced uveitis and laser-induced retinal neovascularization. Consistent with previous polypharmacological studies on chemokine/cytokine release from human macrophages, the prostanoid EP1 receptor played a permissive role in suppressing neovascularization and inflammation in vivo Comparing AGN 211377 with a close structural congener lacking EP1 antagonism (AGN 197727), AGN 197727 was much less active than AGN 211377, but pronounced anti-inflammatory and angiostatic effects were achieved by adding the EP1 antagonist compound (SC-51322) to AGN 197727 in the systemic dosing regimen. Further, AGN 211377 produced superior anti-inflammatory activity compared with the nonsteroidal anti-inflammatory agent ketorolac. These results indicate the value of using a polypharmacological approach in the design of novel therapeutic agents in preference to compounds targeting a

    To observe the clinical efficacy on superior cluneal nerve entrapment syndrome treated by relaxation therapy of in-row multi-needling technique. One hundred and twenty cases were randomized into a multi-needling group, an acupotomy group and a conventional acupuncture group, 40 cases in each one. In the multi-needling group, the perpendicular or oblique puncture was applied to the affected area of the lumbar and gluteal region. The chief needling sites were determined in terms of the strong response of acupuncture to be the chief points. The in-row multi-needling technique was applied around the chief needling sites, with lifting, thrusting penetrating method to different directions. Two chief points were connected with the G6805 low frequency pulse therapeutic apparatus. In the acupotomy group, the acupotomy was applied to 3 to 4 affected sites in each treatment. In the conventional acupuncture group, Shenshu (BL 23), Dachangshu (BL 25), Jiaji (EX-B 2) in the lumbar region, Zhibian (BL 54) and the others were selected and connected with the G6805 low frequency pulse therapeutic apparatus. The cases in each group were treated for 4 weeks. The improvements of pain score, therapeutic efficacy and comprehensive satisfaction assessment were compared among 3 groups in 2 and 4 weeks of treatment separately. The pain scores in each group were reduced apparently in 2 and 4 weeks of treatment separately (all Prelaxation therapy of in-row multi-needling technique achieves the definite therapeutic effect on superior cluneal nerve entrapment syndrome. The efficacy is superior to acupotomy and the conventional acupuncture. The therapeutic effect is better for the cases of the extensive affected scope, unclear location and large distribution in patches caused by the adhesion of muscles and fascia especially.

  10. Advances in anti-obesity therapeutics.

    Science.gov (United States)

    Fong, Tung M

    2005-03-01

    Obesity is rapidly becoming an epidemic in developed countries. Currently available anti-obesity therapeutics are only modestly effective and are accompanied by significant adverse effects. In recent years, substantial advances have been made in the basic understanding of brain control of feeding behaviour and metabolism. As a result, several compounds have progressed to Phase III development, with additional compounds at various stages of Phase II development. Most of the late-stage development candidates are CNS agents, which reflects the consensus that the brain exerts a dominant control on feeding behaviour and peripheral metabolism through the autonomic nervous system. Homeostatic mechanisms encompassing hypothalamic/brainstem pathways have long been recognised in obesity research. In addition, non-homeostatic mechanisms encompassing the reward circuit and volitional control need to be targeted to control feeding behaviour and physical activity, especially in humans. While recognising the importance of CNS control, certain peripherally acting agents can affect mitochondrial metabolism, lipolysis, nutrient absorption or the vagal feedback pathway, such that these peripherally acting agents can potentially be combined with CNS agents to achieve maximal efficacy. It is expected that newer generations of anti-obesity therapeutics will be superior to existing agents and will facilitate lifestyle modification.

    2012-06-01

    Objective The superior transvelar approach is used to access pathologies located in the fourth ventricle and brainstem. The surgical path is below the venous structures, through the superior medullary velum. Following splitting the tentorial edge, near the tentorial apex, the superior medullary velum is split in the cerebello-mesencephalic fissure. Using the supracerebellar infratentorial, transtentorial or parietal interhemispheric routes, the superior medullary velum is approached. Splitting this velum provides a detailed view of the fourth ventricle and its floor. Materials and Methods A total of 10 formalin-fixed specimens were dissected in a stepwise manner to simulate the superior transvelar approach to the fourth ventricle. The exposure gained the distance from the craniotomy site and the ease of access was assessed for each of the routes. We also present an illustrative case, operated by the senior author (AN). Results The superior transvelar approach provides access to the entire length of the fourth ventricle floor, from the aqueduct to the obex, when using the parietal interhemispheric route. In addition, this approach provides access to the entire width of the floor of the fourth ventricle; however, this requires retracting the superior cerebellar peduncle. Using the supracerebellar infratentorial route gives a limited exposure of the superior part of the fourth ventricle. The occipital interhemispheric route is a compromise between these two. Conclusion The superior transvelar approach to the fourth ventricle provides a route for approaching the fourth ventricle from above. This approach does not require opening the posterior fossa in the traditional way, and provides a reasonable alternative for accessing the superior fourth ventricle.

  12. The Dynamic Character of a Psychological Contract between the Superior and the Employee (According to Empirical Research

    2015-12-01

    Full Text Available This article analyses the dynamic character of relationships between superiors and employees in the context of a psychological contract. One of the assumptions is that superiors and employees’ shared understanding of their mutual obligations and expectations underpins the performance of the psychological contract. The article explains the concept of a psychological contract and addresses possible breaches thereto as well as their impact on the shape of relationships between superiors and employees. Information necessary to carry out the analysis was obtained from surveys conducted with 178 representatives of large and medium-sized firms based in Poland and with 800 of their employees. In addition to determining the state and contents of a psychological contract as felt by superiors and employees, the article provides also a description and the rankings of their mutual expectations and obligations related to a psychological contract. The degree of similarity between the opinions of the surveyed superiors and employees on each other’s obligations and expectations was assessed with a specially constructed index (an opinion coincidence index, OCI. the results of the surveys and the direction and amount of OCI’s deviation from show that while employees and superiors frequently differ in the perceptions of their expectations and obligations, there are also areas where their opinions are identical. It has also been found that employees’ perception of the contents of a psychological contract depends on their age and the number of years they have worked in the organisation. This fact points to the dynamic character of a psychological contract.

  15. Estimating the Upcrossings Index

    CERN Document Server

    Sebastião, João Renato; Ferreira, Helena; Pereira, Luísa

    2012-01-01

    For stationary sequences, under general local and asymptotic dependence restrictions, any limiting point process for time normalized upcrossings of high levels is a compound Poisson process, i.e., there is a clustering of high upcrossings, where the underlying Poisson points represent cluster positions, and the multiplicities correspond to cluster sizes. For such classes of stationary sequences there exists the upcrossings index $\\eta,$ $0\\leq \\eta\\leq 1,$ which is directly related to the extremal index $\\theta,$ $0\\leq \\theta\\leq 1,$ for suitable high levels. In this paper we consider the problem of estimating the upcrossings index $\\eta$ for a class of stationary sequences satisfying a mild oscillation restriction. For the proposed estimator, properties such as consistency and asymptotic normality are studied. Finally, the performance of the estimator is assessed through simulation studies for autoregressive processes and case studies in the fields of environment and finance.

    The value of peak width at half-height for the illite 001 XRD reflection is known as the Kubler index or the illite "crystallinity' index. This measurement, which has been related to the degree of metamorphism of very low-grade, pelitic rocks, is a function of at least two crystal-chemical factors: 1) illite X-ray scattering domain size; and 2) illite structural distortions (especially swelling). Reynolds' NEWMOD computer program is used to construct a grid with which these two contributions to illite peak width can be determined independently from measurements of the 001 peak width at half-height and the Srodon intensity ratio. This method yields more information about changes undergone by illite during metamorphism than application of the Kubler index method alone. -Authors

    2014-10-01

    Full Text Available Various indices and scores based on admittedly healthy dietary patterns or food guides for the general population, or aiming at the prevention of diet-related diseases have been developed to assess diet quality. The four indices preferred by most studies are: the Diet Quality Index; the Healthy Eating Index; the Mediterranean Diet Score; and the Overall Nutritional Quality Index. Other instruments based on these indices have been developed and the words 'adapted', 'revised', or 'new version I, II or III' added to their names. Even validated indices usually find only modest associations between diet and risk of disease or death, raising questions about their limitations and the complexity associated with measuring the causal relationship between diet and health parameters. The objective of this review is to describe the main instruments used for assessing diet quality, and the applications and limitations related to their use and interpretation.

    Directory of Open Access Journals (Sweden)

    Jamil Singletary

    2009-01-01

    Full Text Available Circadian clocks gate cellular proliferation and, thereby, therapeutically target availability within proliferative pathways. This temporal coordination occurs within both cancerous and noncancerous proliferating tissues. The timing within the circadian cycle of the administration of drugs targeting proliferative pathways necessarily impacts the amount of damage done to proliferating tissues and cancers. Concurrently measuring target levels and associated key pathway components in normal and malignant tissues around the circadian clock provides a path toward a fuller understanding of the temporal relationships among the physiologic processes governing the therapeutic index of antiproliferative anticancer therapies. The temporal ordering among these relationships, paramount to determining causation, is less well understood using two- or three-dimensional representations. We have created multidimensional multimedia depictions of the temporal unfolding of putatively causative and the resultant therapeutic effects of a drug that specifically targets these ordered processes at specific times of the day. The systems and methods used to create these depictions are provided, as well as three example supplementary movies.

  19. Brown adipose tissue and its therapeutic potential.

    2014-10-01

    Obesity and related diseases are a major cause of human morbidity and mortality and constitute a substantial economic burden for society. Effective treatment regimens are scarce, and new therapeutic targets are needed. Brown adipose tissue, an energy-expending tissue that produces heat, represents a potential therapeutic target. Its presence is associated with low body mass index, low total adipose tissue content and a lower risk of type 2 diabetes mellitus. Knowledge about the development and function of thermogenic adipocytes in brown adipose tissue has increased substantially in the last decade. Important transcriptional regulators have been identified, and hormones able to modulate the thermogenic capacity of the tissue have been recognized. Intriguingly, it is now clear that humans, like rodents, possess two types of thermogenic adipocytes: the classical brown adipocytes found in the interscapular brown adipose organ and the so-called beige adipocytes primarily found in subcutaneous white adipose tissue after adrenergic stimulation. The presence of two distinct types of energy-expending adipocytes in humans is conceptually important because these cells might be stimulated and recruited by different signals, raising the possibility that they might be separate potential targets for therapeutic intervention. In this review, we will discuss important features of the energy-expending brown adipose tissue and highlight those that may serve as potential targets for pharmacological intervention aimed at expanding the tissue and/or enhancing its function to counteract obesity.

    Brown syndrome is a rare strabismic disease characterized by a limited elevation in adduction of the eye. The lengthening/weakening of superior oblique muscle is the main way of surgical intervention for this disease. A 7-year-old boy was diagnosed as having acquired Brown syndrome in his right eye after injury in his face. We experienced successful release of this Brown syndrome through mere pulling outward of superior oblique tendon during surgical exploration. We briefly discuss why this manipulation of superior oblique tendon that we performed was successful.

    The right superior vena cava draining into the left atrium is a rare malformation causing cyanosis and clubbing in patients in whom no other signs of congenital heart defect are present. Diagnosis may be difficult as cyanosis may be mild and the anomaly is not always easily detectable by echocardiography. For this reason we report a 13-month-old male in whom we confirmed the clinical and echocardiographic suspicion of anomalous drainage of the right superior vena cava using multidetector CT. This allowed successful surgical reconnection of the right superior vena cava to the right atrium. (orig.)

  5. Noise management to achieve superiority in quantum information systems

    Nemoto, Kae; Devitt, Simon; Munro, William J.

    2017-06-01

    Quantum information systems are expected to exhibit superiority compared with their classical counterparts. This superiority arises from the quantum coherences present in these quantum systems, which are obviously absent in classical ones. To exploit such quantum coherences, it is essential to control the phase information in the quantum state. The phase is analogue in nature, rather than binary. This makes quantum information technology fundamentally different from our classical digital information technology. In this paper, we analyse error sources and illustrate how these errors must be managed for the system to achieve the required fidelity and a quantum superiority. This article is part of the themed issue 'Quantum technology for the 21st century'.

    Davies, C. S.; Kruglyak, V. V.

    2015-10-01

    The wave solutions of the Landau-Lifshitz equation (spin waves) are characterized by some of the most complex and peculiar dispersion relations among all waves. For example, the spin-wave ("magnonic") dispersion can range from the parabolic law (typical for a quantum-mechanical electron) at short wavelengths to the nonanalytical linear type (typical for light and acoustic phonons) at long wavelengths. Moreover, the long-wavelength magnonic dispersion has a gap and is inherently anisotropic, being naturally negative for a range of relative orientations between the effective field and the spin-wave wave vector. Nonuniformities in the effective field and magnetization configurations enable the guiding and steering of spin waves in a deliberate manner and therefore represent landscapes of graded refractive index (graded magnonic index). By analogy to the fields of graded-index photonics and transformation optics, the studies of spin waves in graded magnonic landscapes can be united under the umbrella of the graded-index magnonics theme and are reviewed here with focus on the challenges and opportunities ahead of this exciting research direction.

Finally, we develop an efficient indexing scheme to answer approximate nearest-neighbor queries among moving points.......We propose three indexing schemes for storing a set S of N points in the plane, each moving along a linear trajectory, so that any query of the following form can be answered quickly: Given a rectangle R and a real value t, report all K points of S that lie inside R at time t. We first present...... an indexing structure that, for any given constant >0, uses O(N/B) disk blocks and answers a query in O((N/B)1/2+ +K/B) I/Os, where B is the block size.

    2011-01-01

    $Local^{3}$ Index Theorem means $Local(Local(Local \\;Index \\; Theorem)))$. $Local \\; Index \\; Theorem$ is the Connes-Moscovici local index theorem \\cite{Connes-Moscovici1}, \\cite{Connes-Moscovici2}. The second "Local" refers to the cyclic homology localised to a certain separable subring of the ground algebra, while the last one refers to Alexander-Spanier type cyclic homology. The Connes-Moscovici work is based on the operator $R(A) = \\mathbf{P} - \\mathbf{e}$ associated to the elliptic pseudo-differential operator $A$ on the smooth manifold $M$, where $\\mathbf{P}$, $\\mathbf{e}$ are idempotents, see \\cite{Connes-Moscovici1}, Pg. 353. The operator $R(A)$ has two main merits: it is a smoothing operator and its distributional kernel is situated in an arbitrarily small neighbourhood of the diagonal in $M \\times M$. The operator $R(A)$ has also two setbacks: -i) it is not an idempotent (and therefore it does not have a genuine Connes-Chern character); -ii) even if it were an idempotent, its Connes-Chern character ...

    The significance and diagnostic value of semen analysis in chronic bacterial prostatitis has been extensively debated and remains controversial. To investigate the diagnostic relevance of semen culture in the bacteriological workup of prostatitis patients, we retrospectively analyzed a clinical database of 696 symptomatic patients. All patients were routinely subjected to a four-glass test, followed by semen culture and analysis. This allowed to dissect from the database three different diagnostic scenarios, and to compare the 'two-glass' pre-/post- massage test and the standard 'four-glass' test with a 'five-glass' test (four-glass plus post-VB3 semen culture). The 'five-glass' test showed 3.6- or 6.5-fold increases in relative sensitivity and lesser reductions (−13.2% or −14.7%) in relative specificity for traditional uropathogens (TUs) compared with the four-glass or two-glass test, respectively. The area under the ROC curve and Jouden's index were increased, whereas positive and negative likelihood ratios were lower than comparators, indicating that the 'five-glass' assay may be superior in confirming the negative outcome of both standard tests. The five-, four-, and two-glass tests detected TUs (Enterobacteriaceae, Enterococci, etc.) in 120, 33, and 20 patients and unusual pathogens (Streptococci, other Gram-positive species, Mycoplasmata, and others) in 130, 56, and 45 patients, respectively. When patients were subjected to pharmacological treatment, including a combination of a fluoroquinolone and a macrolide, no differences in eradication rates were observed between groups diagnosed with different tests, irrespective of pathogen category. Eradication was associated with long-term sign/symptom remission; no significant intergroup differences in sign/symptom scores were observed throughout a 24-month off-therapy follow-up period. In conclusion, our data support the usefulness of semen analysis in the diagnostic workup of prostatitis patients when this

    Nuclear transfer and therapeutic cloning have widespread and attractive prospects in animal agriculture and biomedical applications. We reviewed that the quality of oocytes and nuclear reprogramming of somatic donor cells were the main reasons of the common abnormalities in cloned animals and the low efficiency of cloning and showed the problems and outlets in therapeutic cloning, such as some basic problems in nuclear transfer affected clinical applications of therapeutic cloning. Study on isolation and culture of nuclear transfer embryonic stem (ntES) cells and specific differentiation of ntES cells into important functional cells should be emphasized and could enhance the efficiency. Adult stem cells could help to cure some great diseases, but could not replace therapeutic cloning. Ethics also impeded the development of therapeutic cloning. It is necessary to improve many techniques and reinforce the research of some basic theories, then somatic nuclear transfer and therapeutic cloning may apply to agriculture reproduction and benefit to human life better.

  8. Implementation of nanoparticles in therapeutic radiation oncology

    2017-05-01

    Development and progress of cancer is a very complex disease process to comprehend because of the multiple changes in cellular physiology, pathology, and pathophysiology resulting from the numerous genetic changes from which cancer originates. As a result, most common treatments are not directed at the molecular level but rather at the tissue level. While personalized care is becoming an increasingly aim, the most common cancer treatments are restricted to chemotherapy, radiation, and surgery, each of which has a high likelihood of resulting in rather severe adverse side effects. For example, currently used radiation therapy does not discriminate between normal and cancerous cells and greatly relies on the external targeting of the radiation beams to specific cells and organs. Because of this, there is an immediate need for the development of new and innovative technologies that help to differentiate tumor cells and micrometastases from normal cells and facilitate the complete destruction of those cells. Recent advancements in nanoscience and nanotechnology have paved a way for the development of nanoparticles (NPs) as multifunctional carriers to deliver therapeutic radioisotopes for tumor targeted radiation therapy, to monitor their delivery, and improve the therapeutic index of radiation and tumor response to the treatment. The application of NPs in radiation therapy has aimed to improve outcomes in radiation therapy by increasing therapeutic effect in tumors and reducing toxicity on normal tissues. Because NPs possess unique properties, such as preferential accumulation in tumors and minimal uptake in normal tissues, it makes them ideal for the delivery of radiotherapy. This review provides an overview of the recent development of NPs for carrying and delivering therapeutic radioisotopes for systemic radiation treatment for a variety of cancers in radiation oncology.

  9. Designing phage therapeutics.

    Science.gov (United States)

    Goodridge, Lawrence D

    2010-01-01

    Phage therapy is the application of phages to bodies, substances, or environments to effect the biocontrol of pathogenic or nuisance bacteria. To be effective, phages, minimally, must be capable of attaching to bacteria (adsorption), killing those bacteria (usually associated with phage infection), and otherwise surviving (resisting decay) until they achieve attachment and subsequent killing. While a strength of phage therapy is that phages that possess appropriate properties can be chosen from a large diversity of naturally occurring phages, a more rational approach to phage therapy also can include post-isolation manipulation of phages genetically, phenotypically, or in terms of combining different products into a single formulation. Genetic manipulation, especially in these modern times, can involve genetic engineering, though a more traditional approach involves the selection of spontaneously occurring phage mutants during serial transfer protocols. While genetic modification typically is done to give rise to phenotypic changes in phages, phage phenotype alone can also be modified in vitro, prior to phage application for therapeutic purposes, as for the sake of improving phage lethality (such as by linking phage virions to antibacterial chemicals such as chloramphenicol) or survival capabilities (e.g., via virion PEGylation). Finally, phages, both naturally occurring isolates or otherwise modified constructs, can be combined into cocktails which provide collectively enhanced capabilities such as expanded overall host range. Generally these strategies represent different routes towards improving phage therapy formulations and thereby efficacy through informed design.

    Superior vena cava syndrome is the obstruction of the superior vena cava or its main tributaries by benign or malignant lesions. The syndrome causes edema and engorgement of the vessels on the face, neck, and arms, nonproductive cough, and dyspnea. We discuss the case of a 48-year-old obese diabetic woman who was admitted with unstable angina. She had previously been diagnosed with superior vena cava syndrome. Urgent coronary artery bypass grafting was necessary Although thousands of coronary artery bypasses are performed every year, there are not many reports on patients with superior vena cava syndrome who successfully undergo cardiopulmonary bypass and coronary artery grafting with an internal mammary artery as the conduit. The results of the case and alternative recommended methods are discussed.

    2003-01-01

    Nuclear transfer technology can be applied to produce autologous differentiated cells for therapeutic purposes, a concept termed therapeutic cloning. Countless articles have been published on the ethics and politics of human therapeutic cloning, reflecting the high expectations from this new opportunity for rejuvenation of the aging or diseased body. Yet the research literature on therapeutic cloning, strictly speaking, is comprised of only four articles, all in the mouse. The efficiency of derivation of embryonic stem cell lines via nuclear transfer is remarkably consistent among these reports. However, the efficiency is so low that, in its present form, the concept is unlikely to become widespread in clinical practice. PMID:12949262

Lawrence (2001 computed the percentage increase across 1,494 venues containing at least five offline and five online articles. Results shown an average of 336% more citations to online articles compared to offline articles published in the same venue. If articles published in the same venue are of similar quality, then they concluded that online articles are more highly cited because of their easier access. Thomson Scientific, traditionally concerned with printed journals, announced on November 28, 2005, the launch of Web Citation Index™, the multidisciplinary citation index of scholarly content from institutional and subject-based repositories (http://scientific.thomson. com/press/2005/8298416/. The Web Citation Index from the abstracting and indexing (A&I connects together pre-print articles, institutional repositories and open access (OA journals (Chillingworth, 2005. Basically all research funds are government granted funds, tax payer’s supported and therefore, results should be made freely available to the community. Free online availability facilitates access to research findings, maximizes interaction among research groups, and optimizes efforts and research funds efficiency.

    Superior memorizers often employ the method of loci (MoL) to memorize large amounts of information. The MoL, known since ancient times, relies on a complex process where information to be memorized is bound to landmarks along mental routes in a previously memorized environment. However, functional magnetic resonance imaging data on groups of trained superior memorizer are rare. Based on the memorizing strategy reported by superior memorizers, we developed a scheme of the processes successively employed during memorizing and recalling digits and relate these to brain activation that is specific for the encoding and recall period. In the examined superior memorizers several regions, suggested to be involved in mental navigation and digit-to-word processing, were specifically activated during encoding: bilateral early visual cortex, retrosplenial cortex, left parahippocampus, left visual cortex, and left superior parietal cortex. Although the scheme suggests that some steps during encoding and recall seem to be analog, none of the encoding areas were specifically activated during the recall. Instead, we found strong activation in left anterior superior temporal gyrus, which we relate to recalling the sequential order of the digits, and right motor cortex that may be related to reciting the digits.

    Background The result would be disastrous if the superior pulmonary sulcus tumor (Pancoast tumor) was misdiagnosed as degenerative cervical spine diseases.The aim of this study was to investigate the differential diagnosis methods of cervical radiculopathy and superior pulmonary sulcus tumor.Methods Clinical manifestations,physical,and radiological findings of 10 patients,whose main complaints were radiating shoulder and arm pain and later were diagnosed with superior pulmonary sulcus tumor,were reviewed and compared with those of cervical radiculopathy.Results Superior pulmonary sulcus tumor patients have shorter mean history and fewer complaints of neck pain or limitation of neck movement.Physical examination showed almost normal cervical spine range of motion.Spurling's neck compression test was negative in all patients.Anteroposterior cervical radiographs showed the lack of pulmonary air at the top of the affected lung in all cases and first rib encroachment in one case.The diagnosis of superior pulmonary sulcus tumor can be further confirmed by CT and MRI.Conclusions By the method of combination of history,physical examination,and radiological findings,superior pulmonary sulcus tumor can be efficiently differentiated from cervical radiculopathy.Normal motion range of the cervical spine,negative Spurling's neck compression test,and the lack of pulmonary air at the top of the affected lung in anteroposterior cervical radiographs should be considerad as indications for further chest radiograph examinations.

Mostramos um caso de um paciente submetido a radiografia de tórax e tomografia computadorizada para avaliação de doença pulmonar obstrutiva crônica, tendo como achado a persistência da veia cava superior esquerda com ausência da direita, sem qualquer cardiopatia associada e com a drenagem cardíaca sendo feita, através do seio coronariano, para o átrio direito.Persistent left superior vena cava with absent right superior vena cava is a rare anomaly, with less than 150 cases reported in the literature. Congenitally persistent left superior vena cava is the most common variant of systemic venous return to the heart, resulting embryologically from failure of the left anterior cardinal vein to become obliterated. Its incidence varies from 0.3% in patients with otherwise normal heart to 4.3% in patients with congenital heart disease. In the majority of the patients, a right superior vena cava is present as well, but rarely the right anterior cardinal vein degenerates resulting in the absence of the normal right superior vena cava.

  20. Purinergic Signalling: Therapeutic Developments

    Directory of Open Access Journals (Sweden)

    Geoffrey Burnstock

    2017-09-01

    Full Text Available Purinergic signalling, i.e., the role of nucleotides as extracellular signalling molecules, was proposed in 1972. However, this concept was not well accepted until the early 1990’s when receptor subtypes for purines and pyrimidines were cloned and characterised, which includes four subtypes of the P1 (adenosine receptor, seven subtypes of P2X ion channel receptors and 8 subtypes of the P2Y G protein-coupled receptor. Early studies were largely concerned with the physiology, pharmacology and biochemistry of purinergic signalling. More recently, the focus has been on the pathophysiology and therapeutic potential. There was early recognition of the use of P1 receptor agonists for the treatment of supraventricular tachycardia and A2A receptor antagonists are promising for the treatment of Parkinson’s disease. Clopidogrel, a P2Y12 antagonist, is widely used for the treatment of thrombosis and stroke, blocking P2Y12 receptor-mediated platelet aggregation. Diquafosol, a long acting P2Y2 receptor agonist, is being used for the treatment of dry eye. P2X3 receptor antagonists have been developed that are orally bioavailable and stable in vivo and are currently in clinical trials for the treatment of chronic cough, bladder incontinence, visceral pain and hypertension. Antagonists to P2X7 receptors are being investigated for the treatment of inflammatory disorders, including neurodegenerative diseases. Other investigations are in progress for the use of purinergic agents for the treatment of osteoporosis, myocardial infarction, irritable bowel syndrome, epilepsy, atherosclerosis, depression, autism, diabetes, and cancer.

    Therapy of mitochondrial encephalomyopathies (defined restrictively as defects of the mitochondrial respiratory chain) is woefully inadequate, despite great progress in our understanding of the molecular bases of these disorders. In this review, we consider sequentially several different therapeutic approaches. Palliative therapy is dictated by good medical practice and includes anticonvulsant medication, control of endocrine dysfunction, and surgical procedures. Removal of noxious metabolites is centered on combating lactic acidosis, but extends to other metabolites. Attempts to bypass blocks in the respiratory chain by administration of electron acceptors have not been successful, but this may be amenable to genetic engineering. Administration of metabolites and cofactors is the mainstay of real-life therapy and is especially important in disorders due to primary deficiencies of specific compounds, such as carnitine or coenzyme Q10. There is increasing interest in the administration of reactive oxygen species scavengers both in primary mitochondrial diseases and in neurodegenerative diseases directly or indirectly related to mitochondrial dysfunction. Aerobic exercise and physical therapy prevent or correct deconditioning and improve exercise tolerance in patients with mitochondrial myopathies due to mitochondrial DNA (mtDNA) mutations. Gene therapy is a challenge because of polyplasmy and heteroplasmy, but interesting experimental approaches are being pursued and include, for example, decreasing the ratio of mutant to wild-type mitochondrial genomes (gene shifting), converting mutated mtDNA genes into normal nuclear DNA genes (allotopic expression), importing cognate genes from other species, or correcting mtDNA mutations with specific restriction endonucleases. Germline therapy raises ethical problems but is being considered for prevention of maternal transmission of mtDNA mutations. Preventive therapy through genetic counseling and prenatal diagnosis is

    Full Text Available Trichomoniasis is frequent, parasitic and sexually transmitted infection of genitourinary tract. It is treated by metronidazole (5-nitroimidazole according to protocol recommended by Center for Disease Control (CDC formerly called: Communicable Disease Center [19]. The resistance of Trichomonas vaginalis (TV strains to metronidazole (MND was described in USA in 1960, and later on in many European countries [8, 9, 10, 11, 12, 13]. In these cases, due to persistent trichomonas infection, it is necessary to repeat MND treatment with moderate modification of dose and/or length of its application. Nevertheless, oncogenic and toxic effects of MND have to be taken into consideration. OBJECT The aim of this study was to investigate and analyze the incidence of TV in STD and lower susceptibility of certain TV strains to MND were analyzed. MATERIAL AND METHODS In three-year period (1999-2001 612 patients (244 females and 368 males suspected of STD were examined clinically and microbiologically at the Institute of Dermatovenereology in Belgrade. The patients detected for TV were treated according to CDC protocol. The affected were considered cured if there was no manifest clinical infection, and no TV verified by microbiological test. Results TV was isolated in 216 patients (35.29 % of all subjects. Trichomonas infection was found in 90 (36.88 % out of 244 tested females and in 126 (32.34 % of 368 males. Clinically manifested infection, with extensive urethral and vaginal secretion, was recorded in 161 patients, while the asymptomatic form was found in 55 subjects. This result indicates the predominance of manifested trichomonas infections (75.54 % of cases. The difference of distribution of clinical forms of trichomoniasis, in relation to sex, was not statistically significant (c2=0.854; p>0.05. The patients with verified trichomonas infection were treated by metronidazole according to CDC protocol. The recommended therapeutical scheme consisted of three

    A wide variety of full-size monoclonal antibodies (mAbs) and therapeutics derived from alternative antibody formats can be produced through genetic and biological engineering techniques. These molecules are now filling the preclinical and clinical pipelines of every major pharmaceutical company and many biotechnology firms. Metrics for the development of antibody therapeutics, including averages for the number of candidates entering clinical study and development phase lengths for mAbs approved in the United States, were derived from analysis of a dataset of over 600 therapeutic mAbs that entered clinical study sponsored, at least in part, by commercial firms. The results presented provide an overview of the field and context for the evaluation of on-going and prospective mAb development programs. The expansion of therapeutic antibody use through supplemental marketing approvals and the increase in the study of therapeutics derived from alternative antibody formats are discussed.

    Bacteriophages (phages), discovered 100 years ago, are able to infect and destroy only bacterial cells. In the current crisis of antibiotic efficacy, phage therapy is considered as a supplementary or even alternative therapeutic approach. Evolution of multidrug-resistant and pandrug-resistant bacterial strains poses a real threat, so it is extremely important to have the possibility to isolate new phages for therapeutic purposes. Our phage laboratory and therapy center has extensive experience with phage isolation, characterization, and therapeutic application. In this article we present current progress in bacteriophages isolation and use for therapeutic purposes, our experience in this field and its practical implications for phage therapy. We attempt to summarize the state of the art: properties of phages, the methods for their isolation, criteria of phage selection for therapeutic purposes and limitations of their use. Perspectives for the use of genetically engineered phages to specifically target bacterial virulence-associated genes are also briefly presented.

    To evaluate the accuracy of venous filling index on standing (VFIst) and a new index named pure regurgitation index (PRI), obtained by air plethysmography, for detecting venous reflux. One hundred and sixty-one healthy subjects (161 limbs) and 180 varicose vein patients (180 limbs) were investigated. All subjects underwent duplex ultrasonography for verifying venous reflux and air plethysmography to obtain hemodynamic parameters such as VFIst, VFI in the supine position (VFIsu), and the maximum arterial inflow rate. To evaluate the accuracy of VFIst and PRI (= (VFIst - VFIsu)/body mass index), receiver operating characteristics curves were created. The optimal cut-off value, sensitivity, specificity, and area under the curve, obtained from analyzing the receiver operating characteristics curves, of VFIst vs. PRI were 2.058 mL/s vs. 0.059 mL · m(2)/s · kg, 93.3% vs. 90.3%, 88.8% vs. 91.3%, and 0.954 vs. 0.964, respectively. This study indicates that while both VFIst and PRI are highly accurate indicators of venous reflux, PRI, which is not affected by the arterial inflow rate and body mass index, is slightly superior to VFIst, especially in subjects with greater body mass index.

    Inhale, in colaboration with Pfizer and Aventis Pharma (formerly Hoechst Marion Roussel; HMR), is developing an insulin formulation utilizing its pulmonary delivery technology for macromolecules for the potential treatment of type I and II diabetes. By July 2001, the phase III program had been completed and the companies had begun to assemble data for MAA and NDA filings; however, it was already clear at this time that additional data might be required for filing. By December 2001, it had been decided that the NDA should include an increased level of controlled, long-term pulmonary safety data in diabetic patients and a major study was planned to be completed in 2002, with the NDA filed thereafter (during 2002). US-05997848 was issued to Inhale Therapeutic Systems in December 1999, and corresponds to WO-09524183, filed in February 1995. Equivalent applications have appeared to date in Australia, Brazil, Canada, China, Czech Republic, Europe, Finland, Hungary, Japan, Norway, New Zealand, Poland and South Africa. This family of applications is specific to pulmonary delivery of insulin. In February 1999, Lehman Brothers gave this inhaled insulin a 60% probability of reaching market, with a possible launch date of 2001. The analysts estimated peak sales at $3 billion in 2011. In May 2000, Aventis predicted that estimated peak sales would be in excess of $1 billion. In February 2000, Merrill Lynch expected product launch in 2002 and predicted that it would be a multibillion-dollar product. Analysts Merril Lynch predicted, in September and November 2000, that the product would be launched by 2002, with sales in that year of e75 million, rising to euro 500 million in 2004. In April 2001, Merrill Lynch predicted that filing for this drug would occur in 2001. Following the report of the potential delay in regulatory filing, issued in July 2001, Deutsche Banc Alex Brown predicted a filing would take place in the fourth quarter of 2002 and launch would take place in the first

    Abstract Background: Dextrocardia, or right-lying heart, is an uncommon congenital heart disease in which the apex of the heart is located on the right side of chest. Persistent left superior vena cava (PLSVA) is a rare venous anomaly that is often associated with the abnormalities of cardiac transduction system. A case with combination of dextrocardia, persistent left superior vena cava, and sick sinus syndrome has not been reported. Methods: We used different techniques including cardiac color Doppler echocardiography, 24-hour Holter monitoring, and abdominal ultrasound to make a diagnosis and treated the patient by implanting a VVI pacemaker. Results: A 50-year-old woman was admitted with a syncope. Angiography of the right atrium and superior vena cava, echocardiography, electrocardiography, and abdominal ultrasound revealed the presence of the combination of mirror image dextrocardia, PLSVA, and sick sinus syndrome. The complex structural anomalies presented great technical challenges for interventional treatments. After thorough examination and understanding of the structural anatomy and anomalies of the superior and inferior vena cava and cardiac chambers, we successfully treated this patient by implanting a VVI pacemaker. Conclusion: Physicians must be aware of the complexity of the morphological and anatomical structures of dextrocardia accompanying PLSVC. Given that the diagnosis of situs inversus was performed at a relatively advanced age, it is therefore important to make such a correct diagnosis followed by appropriate therapeutic intervention.

    Splanchnic artery aneurysms are rare in children. High mortality from rupture justifies its treatment, with various therapeutic options among which stand out surgery and recently, endovascular treatment. A 11 year old girl presented with abdominal pain and sudden drop in hematocrit. The urgent abdominal CT angiography showed a saccular aneurysm of the superior mesenteric artery (SMA) at 4 cm from the ostium with dissection and active bleeding. A selective angiography was performed which confirmed the dissection. A self-expanding stent was placed in the main trunk of the SMA and a transcatheter coil and onyx embolization of the aneurysm was performed. The control angiogram showed no evidence of residual perfusion of the false lumen and demonstrated proper vascularization of the distal jejunum-ileal branches. Dual antiplatelet therapy with aspirin and dipyridamole was begun. After 24 months of follow-up the patient is asymptomatic. Endovascular treatment of a SMA aneurysm is effective in the pediatric patient, even in emergency situations.

    We investigated the efficacy and safety of two different treatments that have not been evaluated in peripuberty boys with hypogonadotropic hypogonadism (HH). The objective of the study was to assess the effectiveness and safety of GnRH or human chorionic gonadotropin (hCG) treatment in adolescent boys with HH. Twelve patients received 8-10 μg of GnRH, sc injected every 90 minutes using a pump. Another 22 patients received hCG, injected im as follows: for the first 3 months, 1000 IU of hCG was injected two times per week and then once every other day for the next 3 months. The dose of hCG was increased to 2000 IU after a 6-month treatment and the above cycle was repeated for another 6 months. All patients were treated for 12-14 months and followed up every 3 months. Thirty-five participants were chosen from Beijing Children's Hospital from 2008 to 2014. Twenty-three patients with Kallmann syndrome and 12 with normosmic idiopathic hypogonadotropic hypogonadism. The age ranged from 10 to 16 years. Twelve patients were treated with pulsatile pump GnRH (group 1), and 22 patients were treated with im hCG (group 2). One patient was treated successively with hCG and GnRH, which was removed in data analysis. Testicular volume was measured by an orchidometer. The levels of T, LH, and FSH serum were measured with a chemiluminesent immunoassay. Bone age was measured by x-ray. Patients treated with GnRH showed larger testes than those treated with hCG. Patients in both groups showed a significantly increased length of penis and T levels. But the difference of the two groups was not statistically significant. There was no significant difference in side effects in both groups. Boys with HH may be effectively treated with GnRH. We suggested that GnRH exhibits higher efficacy in treating adolescent boys with HH than hCG.

  16. The therapeutic potential of aromatase inhibitors.

    The third generation aromatase inhibitors are both remarkably potent and specific endocrine agents inhibiting aromatase activity and reducing circulating oestrogen levels in postmenopausal women to levels never previously seen. Their therapeutic potential is consequently much greater than the earlier prototype drugs. Their excellent side-effect profile also allows for potential wider indications in the treatment of oestrogen-related diseases, including breast cancer. It still remains to determine whether their potent endocrine effects translate into increased therapeutic benefit. In advanced breast cancer, aromatase inhibitors have been shown to have improved efficacy and toxicity profiles when compared with progestins, aminoglutethimide and tamoxifen. Aromatase inhibitors have also been used in the neoadjuvant setting, where they have been shown to achieve higher response rates than tamoxifen and to be more successful at downstaging tumours. Early results comparing an aromatase inhibitor with tamoxifen in the adjuvant setting in early breast cancer show anastrozole to be superior to tamoxifen in terms of both disease-free survival and a lower incidence of new contralateral tumours. There was also a more favourable side-effect profile, which has implications for potential future prophylactic treatment. Additionally, since aromatase inhibitors have different mechanisms of action, unlike antioestrogens, they may be particularly useful as chemopreventive agents if oestrogens are themselves genotoxic. Aromatase inhibitors have been used to date almost exclusively in postmenopausal women. The potential of combining them with luteinising hormone-releasing hormone analogues allows the possibility of treating premenopausal women with either oestrogen receptor-positive breast cancer or benign conditions such as cyclical breast pain, fibroadenomata, recurrent cystic disease or endometriosis. There is also the potential for their use in men with conditions such as

    Full Text Available Superior semicircular canal dehiscence syndrome was first reported by Lloyd Minor and colleagues in 1998. Patients with a dehiscence in the bone overlying the superior semicircular canal experience symptoms of pressure or sound-induced vertigo, bone conduction hyperacusis, and pulsatile tinnitus. The initial series of patients were diagnosed based on common symptoms, a physical examination finding of eye movements in the plane of the superior semicircular canal when ear canal pressure or loud tones were applied to the ear, and high-resolution computed tomography imaging demonstrating a dehiscence in the bone over the superior semicircular canal. Research productivity directed at understanding better methods for diagnosing and treating this condition has substantially increased over the last two decades. We now have a sound understanding of the pathophysiology of third mobile window syndromes, higher resolution imaging protocols, and several sensitive and specific diagnostic tests. Furthermore, we have a treatment (surgical occlusion of the superior semicircular canal that has demonstrated efficacy. This review will highlight some of the fundamental insights gained in SCDS, propose diagnostic criteria, and discuss future research directions.

    Full Text Available Objective: Preclinical and very limited clinical studies suggest that sildenafil may have therapeutic potential in selected neurological disorders. However, many neurological side effects of sildenafil have been reported. This work aimed to clarify the histopathological effect of sildenafil citrate on the superior colliculus (SC of adult male albino rat. Material and methods: 24 adult male albino rats were used and divided into 4 groups. The first 3 groups were received respectively sildenafil citrate orally at doses 0.25, 0.70 and 1.43mg/kg body weight daily for 30 days while the 4th group was used as control. At end of the treatment, the superior colliculi were undergone light and electron microscopic investigation. Results: In the control group, superficial part of the SC has neural cells and myelinated nerve fibers. With least dose of sildenafil, the superficial part of SC revealed disturbance in neural tissue with dilated capillaries and vacuoles. Some neurons showed deeply stained nuclei shrunken cytoplasm. Some cells showed enlarged mitochondria and dilated endoplasmic reticulum. With medium dose of sildenafil, SC showed more disturbances; stripped myelin sheaths or widely separated myelin lamellae, dilated blood vessels with large vacuoles around them and many neurons with apoptotic criteria. However, maximum dose of sildenafil induced massive destruction of edematous neural tissue; invasion of the surface with massive blood vessels, marked decrease in thickness of myelin sheaths and the neural cells revealed degenerative and apoptotic changes. The mean number and size of cells revealed significantly progressive decrease in all treated rats with increasing doses of the drug. Conclusion: Long-term, daily use of sildenafil can lead to pathological effect in the superior colliculus which may be implicated in visual disturbance and this effect is dose dependent, so neurological effect of sildenafil necessitates further investigations.

    Technical trading rules have a long history of being used by practitioners in financial markets. The profitable ability and efficiency of technical trading rules are yet controversial. In this paper, we test the performance of more than seven thousand traditional technical trading rules on the Shanghai Securities Composite Index (SSCI) from May 21, 1992 through June 30, 2013 and China Securities Index 300 (CSI 300) from April 8, 2005 through June 30, 2013 to check whether an effective trading strategy could be found by using the performance measurements based on the return and Sharpe ratio. To correct for the influence of the data-snooping effect, we adopt the Superior Predictive Ability test to evaluate if there exists a trading rule that can significantly outperform the benchmark. The result shows that for SSCI, technical trading rules offer significant profitability, while for CSI 300, this ability is lost. We further partition the SSCI into two sub-series and find that the efficiency of technical trading in sub-series, which have exactly the same spanning period as that of CSI 300, is severely weakened. By testing the trading rules on both indexes with a five-year moving window, we find that during the financial bubble from 2005 to 2007, the effectiveness of technical trading rules is greatly improved. This is consistent with the predictive ability of technical trading rules which appears when the market is less efficient.

    PurposeTo assess the feasibility, effectiveness, and safety of catheter-directed thrombolysis and aspiration thrombectomy therapy by combined route of superior mesenteric vein and artery (SMV+SMA) for acute superior mesenteric venous thrombosis (ASMVT).MethodsThis retrospective study reviewed eight ASMVT patients with transcatheter direct thrombolysis and aspiration thrombectomy therapy via SMV and indirect thrombolysis via SMA during a period of 14 months. The demographics, etiology, risk factors, therapeutic effect, complications, mortality, and follow-up of the study population were assessed. Anatomic and imaging classification of location and extent of thrombus at diagnosis and degree of thrombus lysis were described.ResultsTechnical success was achieved with substantial improvement in symptoms and thrombus resolution after thrombolytic therapy in all patients. The local urokinase infusion by SMA and SMV was performed for 5–7 (6.13 ± 0.83) and 7–15 (12 ± 2.51) days. Anticoagulation was performed catheter-directed and then orally throughout hospitalization and after discharge. Four patients required delayed localized bowel resection after thrombolytic therapy with no death. Thrombolytic therapy was not interrupted despite minor bleeding at the puncture site in two patients and sepsis in another two postoperatively. Nearly complete removal of thrombus was demonstrated by contrast-enhanced CT scan and portography before discharge. Patients were discharged in 10–27 (19.25 ± 4.89) days after admission. No recurrence developed during the follow-up of 10–13 (12.13 ± 0.99) months.ConclusionsCatheter-directed thrombolytic and aspiration therapy via SMV+SMA is beneficial for ASMVT in avoiding patient death, efficient resolving thrombus, rapid improving symptoms, reversing extensive intestinal ischemia, averting bowel resection, or localizing infarcted bowel segment and preventing short bowel syndrome.

    Full Text Available Importance. Superior semicircular canal dehiscence (SCD is a third window lesion of the inner ear causing symptoms of vertigo, autophony, tinnitus, and hearing loss. A “two-hit” hypothesis has traditionally been proposed, whereby thinly developed bone overlying the superior canal is disrupted by a sudden change in intracranial pressure. Although the symptoms of SCD may be precipitated by head injury, no previous reports have described a temporal bone fracture directly causing SCD. Observations. Two patients sustained temporal bone fractures after closed head trauma, and developed unilateral otologic symptoms consistent with SCD. In each instance, computed tomography imaging revealed fractures extending through the bony roof of the superior semicircular canal. Conclusions and Relevance. Temporal bone fractures, which are largely treated nonoperatively, have not previously been reported to cause SCD. As it is a potentially treatable entity, SCD resulting from temporal bone fracture must be recognized as a possibility and diagnosed promptly if present.

    We describe the surgical technique of reimplantation of the right superior pulmonary vein into the left atrium in 2 patients with partial anomalous pulmonary venous connection to the superior vena cava without atrial septal defect. A right axillary minithoracotomy is done through the fourth intercostal space. The pulmonary vein is detached from its origin in the superior vena cava. This is sutured with 6-0 reabsorbable polydioxanone suture (Ethicon, Somerville, NJ). A lateral clamp is applied to the left atrium, and the pulmonary vein is reimplanted. The patient is extubated in the operating room. Neither cardiopulmonary bypass nor blood transfusion was required. It is simple, safe, and reproducible.

    Full Text Available Pyomyositis is a primary bacterial infection of striated muscles nearly always caused by Staphylococcus aureus. Development of the intramuscular abscess involving the extra-ocular muscles (EOMs remains an extremely rare process. We herein present a case of isolated EOM pyomyositis involving superior rectus muscle in a 2-year male child who was referred with complaints of swelling in left eye (LE and inability to open LE since last 1-month. Orbital computed tomography (CT scan showed a well-defined, hypo-dense, peripheral rim-enhancing lesion in relation to left superior rectus muscle suggestive of left superior rectus abscess. The abscess was drained through skin approach. We concluded that pyomyositis of EOM should be considered in any patient presenting with acute onset of orbital inflammation and characteristic CT or magnetic resonance imaging features. Management consists of incision and drainage coupled with antibiotic therapy.

    Anthropogenic climate change has the potential to alter many facets of Earth's freshwater resources, especially lacustrine ecosystems. The effects of anthropogenic changes in Lake Superior, which is Earth's largest freshwater lake by area, are not well documented (spatially or temporally) and predicted future states in response to climate change vary. Here we show that Lake Superior experienced a slow, steady increase in production throughout the Holocene using (paleo)productivity proxies in lacustrine sediments to reconstruct past changes in primary production. Furthermore, data from the last century indicate a rapid increase in primary production, which we attribute to increasing surface water temperatures and longer seasonal stratification related to longer ice-free periods in Lake Superior due to anthropogenic climate warming. These observations demonstrate that anthropogenic effects have become a prominent influence on one of Earth's largest, most pristine lacustrine ecosystems.

    2017-08-06

    Quantum information systems are expected to exhibit superiority compared with their classical counterparts. This superiority arises from the quantum coherences present in these quantum systems, which are obviously absent in classical ones. To exploit such quantum coherences, it is essential to control the phase information in the quantum state. The phase is analogue in nature, rather than binary. This makes quantum information technology fundamentally different from our classical digital information technology. In this paper, we analyse error sources and illustrate how these errors must be managed for the system to achieve the required fidelity and a quantum superiority.This article is part of the themed issue 'Quantum technology for the 21st century'. © 2017 The Author(s).

    Full Text Available There is a tight relationship between information assurance, the intelligence cycle and information superiority within NATO operations. The intelligence cycle has a discrete architecture and provides on-time and relevant intelligence products to the joint force commanders and to other authorized users in a specifi c joint area of operations. The intelligence cycle must follow the evolution of the operation. A permanent intelligence estimate will be performed during the military decision making process and operations execution. Information superiority is one of the most powerful intelligence cycle achievements. and decisively infuences the success of NATO joint operations. Information superiority must be preserved and enhanced through information assurance. Information assurance is an information operation that must be planned by the military in charge of operation security or by non-military experts, executed by all personnel during the entire intelligence cycle life time and employed during the planning and execution of NATO joint operations.

    Hoff, Michael H.; Todd, Thomas N.

    2004-01-01

    The shortjaw cisco (Coregonus zenithicus) was historically found in Lakes Huron, Michigan, and Superior, but has been extirpated in Lakes Huron and Michigan apparently as the result of commercial overharvest. During 1999-2001, we conducted an assessment of shortjaw cisco abundance in five areas, spanning the U.S. waters of Lake Superior, and compared our results with the abundance measured at those areas in 1921-1922. The shortjaw cisco was found at four of the five areas sampled, but abundances were so low that they were not significantly different from zero. In the four areas where shortjaw ciscoes were found, abundance declined significantly by 99% from the 1920s to the present. To increase populations of this once economically and ecologically important species in Lake Superior, an interagency rehabilitation effort is needed. Population monitoring is recommended to assess population trends and to evaluate success of rehabilitation efforts.

  13. Growth Index after Planck

    2013-01-01

    To investigate the possible deviation from the standard $\\Lambda$CDM model and the Einstein's gravity theory in the dynamical perspectives, the growth index $\\gamma_L$ was proposed. Recently, thanks to the measurement of the cosmic growth rate via the redshift-space distortion, one can understand the evolution of density contrast through $f\\sigma_8(z)$, where $f(z)=d\\ln \\delta/d \\ln a$ is the growth rate of matter and $\\sigma_8(z)$ is the rms amplitude of the density contrast $\\delta$ at the comoving $8h^{-1}$ Mpc scale. In this paper, we use the red-shift space distortion data points to investigate the growth index on the bases of the Einstein's gravity theory and a modified gravity theory under the assumption $f=\\Omega_m(a)^{\\gamma_L}$. To fix the background evolution, the cosmic observational data points from the type Ia supernovae SNLS3, cosmic microwave background radiation from {\\it Planck} and baryon acoustic oscillation are used. Via the Markov Chain Monte Carlo method, the $\\gamma_L$ values were obta...

  14. The postdiction superiority effect in metacomprehension of text.

    Pierce, B H; Smith, S M

    2001-01-01

    Metacomprehension accuracy for texts was greater after, rather than before, answering test questions about the texts-a postdiction superiority effect. Although postdiction superiority was found across successive sets of test questions and across successive texts, there was no improvement in metacomprehension accuracy after participants had taken more tests. Neither prediction nor postdiction gamma correlations with test performance improved with successive tests. Although the results are consistent with retrieval hypotheses, they contradict predictions made by test knowledge hypotheses, which state that increasing knowledge of the nature of the tests should increase metacomprehension accuracy.

  15. Imaging Evaluation of Superior Labral Anteroposterior (SLAP) Tears.

    Science.gov (United States)

    Grubin, Jeremy; Maderazo, Alex; Fitzpatrick, Darren

    2015-10-01

    Superior labral anteroposterior (SLAP) tears are common injuries that are best evaluated with magnetic resonance arthrography (MRA), as it provides the most detailed evaluation of the bicipital labral complex. Given the variety and complexity of SLAP tears, distention of the joint with intra-articular dilute gadolinium contrast properly separates the intra-articular biceps tendon, superior labrum, glenoid cartilage and glenohumeral ligaments to optimize assessment of these structures. This allows for increased diagnostic confidence of the interpreting radiologist and provides a better road map for the surgeon prior to arthroscopy. Indirect MRA and high-field magnetic resonance imaging are sensitive and specific alternative modalities if MRA cannot be performed.

    Wu, Ting; Dai, Yun

    2017-02-28

    The tumor microenvironment significantly influences therapeutic response and clinical outcome. Microenvironment-mediated drug resistance can be induced by soluble factors secreted by tumor or stromal cells. The adhesion of tumor cells to stromal fibroblasts or to components of the extracellular matrix can also blunt therapeutic response. Microenvironment-targeted therapy strategies include inhibition of the extracellular ligand-receptor interactions and downstream pathways. Immune cells can both improve and obstruct therapeutic efficacy and may vary in their activation status within the tumor microenvironment; thus, re-programme of the immune response would be substantially more beneficial. The development of rational drug combinations that can simultaneously target tumor cells and the microenvironment may represent a solution to overcome therapeutic resistance.

  8. Acute and chronic effects of clozapine on cholinergic transmission in cultured mouse superior cervical ganglion neurons.

    Cholinergic dysfunction contributes to cognitive deficits in schizophrenia. The atypical antipsychotic clozapine improves cognition in patients with schizophrenia, possibly through modulation of the cholinergic system. However, little is known about specific underlying mechanisms. We investigated the acute and chronic effects of clozapine on cholinergic synaptic transmission in cultured superior cervical ganglion (SCG) neurons. Spontaneous excitatory postsynaptic currents (sEPSCs) were detected and were reversibly inhibited by the nicotinic receptor antagonist d-tubocurarine, confirming that the synaptic responses were primarily mediated by nicotinic receptors. Bath application of clozapine at therapeutic concentrations rapidly and reversely inhibited both the amplitude and frequency of sEPSCs in a concentration-dependent manner, without changing either rise or decay time, suggesting that clozapine effects have both presynaptic and postsynaptic origins. The acute effects of clozapine on sEPSCs were recapitulated by chronic treatment of SCG cultures with similar concentrations of clozapine, as clozapine treatment for 4 d reduced the frequency and amplitude of sEPSCs without affecting their kinetics. Cell survival analysis indicated that SCG neuron cell counts after chronic clozapine treatment were comparable to the control group. These results demonstrate that therapeutic concentrations of clozapine suppress nicotinic synaptic transmission in SCG cholinergic synapses, a simple in vitro preparation of cholinergic transmission.

    The superior drainage was pre-treated by biologic contact oxidation on BOD5 load of 0.72 kg/(m3·d),and then post-treated by constructed wetland. The results about the effect on the constructed wetland post-treatment show that the total nitrogen (TN) is the restrictive index of the combinational technique treatment effect. To meet the reclaimed water quality standard and reuse for waterscape,the peak hydraulic load of constructed wetland is 0.50 m/d in summer (30-36 ℃) and 0.33 m/d in winter (8-12℃),and the load ratio of the peak hydraulic under the two temperature conditions is 3-2. The results are combined of reclaimed water quantity requirements in different seasons of green building. Reasonable scale of the reclaimed water treatment systems can be determined. The treatment efficacy can be well predicted,and both the design and operations can be effectively guided,by which the reclaimed water treatment systems regard superior drainage as the source and are purified by combinational technique of contact oxidation and artificial wetland.

    Full Text Available Purposes: To objectively evaluate the torsional effect of the superior oblique muscle-weakening surgery using the tenectomy technique proposed by Souza-Dias. Methods: The present prospective study included 10 patients (20 eyes with horizontal strabismus, bilateral superior oblique overaction and A-pattern of 15 to 30 prism diopters who underwent superior oblique tenectomy. Objective assessment of ocular torsion was performed by retinography immediately before and one month after surgery. The amount of ocular torsion was determined by measuring the angle formed by a horizontal line drawn across the geometric center of the optic disc and a second line connecting this point to the fovea. Results: The median preoperative angle was 5.56° in the right eyes and -3.43° in the left eyes. The median postoperative angle was 1.84° in the right eyes and -3.12° in the left eyes. The angle variation was statistically significant in both eyes (p=0.012 and p=0.01, respectively. Conclusion: The present study suggests that superior oblique tenectomy has an extorter effect, decreasing the intorsion detected on overaction of this muscle.

    Bronte, C.R.; Moore, S.A.

    2007-01-01

    Historically, Lake Superior has contained many morphologically distinct forms of the lake trout Salvelinus namaycush that have occupied specific depths and locations and spawned at specific times of the year. Today, as was probably the case historically, the siscowet morphotype is the most abundant. Recent interest in harvesting siscowets to extract oil containing omega-3 fatty acids will require additional knowledge of the biology and stock structure of these lightly exploited populations. The objective of this study was to determine whether shape differences exist among siscowet populations across Lake Superior and whether these shape differences can be used to infer stock structure. Morphometric analysis (truss protocol) was used to differentiate among siscowets sampled from 23 locations in Lake Superior. We analyzed 31 distance measurements among 14 anatomical landmarks taken from digital images of fish recorded in the field. Cluster analysis of size-corrected data separated fish into three geographic groups: The Isle Royale, eastern (Michigan), and western regions (Michigan). Finer scales of stock structure were also suggested. Discriminant function analysis demonstrated that head measurements contributed to most of the observed variation. Cross-validation classification rates indicated that 67–71% of individual fish were correctly classified to their region of capture. This is the first study to present shape differences associated with location within a lake trout morphotype in Lake Superior.

    Full Text Available Aim: The superior gluteal nerve may be compromised during hip surgery. We retrospectively evaluated the patients who underwent proximal femoral nailing for unstable trochanteric fractures in order to investigate the presence of superior gluteal nerve injury and its clinical findings. Material and Method: Twenty five patients (14 women, 11 men were included in the study who had femoral nailing between January 2004 and March 2010 at Hamidiye Sisli Etfal Training and Research Hospital Department of Orthopaedics. Two different types of nails which have similar designs and surgical techniques were used for fracture fixation. Patients who had a history of cerebrovascular disease, electromyography findings of polyneuropathy, or degenerative vertebral disease were excluded from the study. Patients were evaluated clinically and radiologically. Findings related to acute denervation in the gluteus medius muscle and motor unit action potential changes were accepted as signs of superior gluteal nerve injury. Results: Eight patients were using support during walking and three of these patients had positive Trendelenburg sign, but only one patient had acute denervation signs of the superior gluteal nerve. Discussion: Based on the present study the incidence of iatrogenic nerve injury is a rare complication of proximal femoral nailing. Elderly patients, regardless of whether they have nerve injury, may limp and need to use a walking support.

    The relationship between auditory perception and vocal production has been typically investigated by evaluating the effect of either altered or degraded auditory feedback on speech production in either normal hearing or hearing-impaired individuals. Our goal in the present study was to examine this relationship in individuals with superior auditory abilities. Thirteen professional musicians and thirteen nonmusicians, with no vocal or singing training, participated in this study. For vocal production accuracy, subjects were presented with three tones. They were asked to reproduce the pitch using the vowel /a/. This procedure was repeated three times. The fundamental frequency of each production was measured using an autocorrelation pitch detection algorithm designed for this study. The musicians' superior auditory abilities (compared to the nonmusicians) were established in a frequency discrimination task reported elsewhere. Results indicate that (a) musicians had better vocal production accuracy than nonmusicians (production errors of 1/2 a semitone compared to 1.3 semitones, respectively); (b) frequency discrimination thresholds explain 43% of the variance of the production data, and (c) all subjects with superior frequency discrimination thresholds showed accurate vocal production; the reverse relationship, however, does not hold true. In this study we provide empirical evidence to the importance of auditory feedback on vocal production in listeners with superior auditory skills.

    Conclusions: In cases in which the superior petrosal sinus and veins are absent, care should be directed to preserving the collateral drainage through the galenic and tentorial tributaries. Although surgical strategies for intraoperative management and preservation of venous structures are still controversial, knowledge of the possible anatomical variations is considered to be essential to improve surgical outcomes.

  7. Review of Cohesion in Indexing

    Full Text Available Indexers often disagree on judging terms that best reflect the content of a document. Difference of opinion highlights one of the characteristics of indexing which is indexing cohesion. Also known as consistency, little study of the subject matter has been undertaken in the past few years. However, its importance has been recently acknowledged in effective information retrieval and expansion of access points to the document content. The present paper investigates cohesion in indexing. In addition of presenting the definitions offered by experts, it takes note of the factors influencing indexing cohesion. Methods for measuring cohesion are offered.

  8. Efficient Index for Handwritten Text

    Science.gov (United States)

    Kamel, Ibrahim

    This paper deals with one of the new emerging multimedia data types, namely, handwritten cursive text. The paper presents two indexing methods for searching a collection of cursive handwriting. The first index, word-level index, treats word as pictogram and uses global features for retrieval. The word-level index is suitable for large collection of cursive text. While the second one, called stroke-level index, treats the word as a set of strokes. The stroke-level index is more accurate, but more costly than the word level index. Each word (or stroke) can be described with a set of features and, thus, can be stored as points in the feature space. The Karhunen-Loeve transform is then used to minimize the number of features used (data dimensionality) and thus the index size. Feature vectors are stored in an R-tree. We implemented both indexes and carried many simulation experiments to measure the effectiveness and the cost of the search algorithm. The proposed indexes achieve substantial saving in the search time over the sequential search. Moreover, the proposed indexes improve the matching rate up to 46% over the sequential search.

    The Solar Index, or, more completely defined as the Service Hot Water Solar Index, was conceptualized during the spring of 1978. The purpose was to enhance public awareness to solar energy usability. Basically, the Solar Index represents the percentage of energy that solar would provide in order to heat an 80 gallon service hot water load for a given location and day. The Index is computed by utilizing SOLCOST, a computer program, which also has applications to space heating, cooling, and heat pump systems and which supplies economic analyses for such solar energy systems. The Index is generated for approximately 68 geographic locations in the country on a daily basis. The definition of the Index, how the project came to be, what it is at the present time and a plan for the future are described. Also presented are the models used for the generation of the Index, a discussion of the primary tool of implementation (the SOLCOST program) and future efforts.

    Very little is known about the biodiversity of freshwater autotrophic picoplankton (APP) in the Laurentian Great Lakes, a system comprising 20% of the world's lacustrine freshwater. In this study, the genetic diversity of Lake Superior APP was examined by analyzing 16S rRNA gene and cpcBA PCR amplicons from water samples. By neighbor joining, the majority of 16S rRNA gene sequences clustered within the "picocyanobacterial clade" consisting of freshwater and marine Synechococcus and Prochlorococcus. Two new groups of Synechococcus spp., the pelagic Lake Superior clusters I and II, do not group with any of the known freshwater picocyanobacterial clusters and were the most abundant species (50 to 90% of the sequences) in samples collected from offshore Lake Superior stations. Conversely, at station Portage Deep (PD), located in a nearshore urbanized area, only 4% of the sequences belonged to these clusters and the remaining clones reflected the freshwater Synechococcus diversity described previously at sites throughout the world. Supporting the 16S rRNA gene data, the cpcBA library from nearshore station PD revealed a cosmopolitan diversity, whereas the majority of the cpcBA sequences (97.6%) from pelagic station CD1 fell within a unique Lake Superior cluster. Thus far, these picocyanobacteria have not been cultured, although their phylogenetic assignment suggests that they are phycoerythrin (PE) rich, consistent with the observation that PE-rich APP dominate Lake Superior picoplankton. Lastly, flow cytometry revealed that the summertime APP can exceed 10(5) cells ml-1 and suggests that the APP shifts from a community of PE and phycocyanin-rich picocyanobacteria and picoeukaryotes in winter to a PE-rich community in summer.

    INTRODUCTION. The hypothesis of Geschwind and Galaburda suggests that specific cognitive superiority arises as a result of an alteration in development of the nervous system. In this article we review the co existence of superiority and inferiority . PATIENTS AND METHODS. A study was made of six children aged between 6 and 8 years old at the Instituto de Belles Artes Antonio Maria Valencia in Cali,Columbia with an educational level between second and third grade at a primary school and of medium low socio economic status. The children were considered to have superior musical ability by music experts, which is the way in which the concept of superiority was to be tested. The concept of inferiority was tested by neuropsychological tests = 1.5 DE below normal for the same age. We estimated the perinatal neurological risk in each case. Subsequently the children s general intelligence and specific cognitive abilities were evaluated. In the first case the WISC R and MSCA were used. The neuropsychological profiles were obtained by broad evaluation using a verbal fluency test, a test using counters, Boston vocabulary test, the Wechster memory scale, sequential verbal memory test, super imposed figures test, Piaget Head battery, Rey Osterrieth complex figure and the Wisconsin card classification test. The RESULTS showed slight/moderate deficits in practical construction ability and mild defects of memory and concept abilities. In general the results supported the hypothesis tested. The mechanisms of superiority proposed in the classical hypothesis mainly involve the contralateral hemisphere: in this study the ipsilateral mechanism was more important.

    Therapeutic interpersonal relationships are the primary component of all health care interactions that facilitate the development of positive clinician–patient experiences. Therapeutic interpersonal relationships have the capacity to transform and enrich the patients’ experiences. Consequently, with an increasing necessity to focus on patient-centered care, it is imperative for health care professionals to therapeutically engage with patients to improve health-related outcomes. Studies were identified through an electronic search, using the PubMed, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO databases of peer-reviewed research, limited to the English language with search terms developed to reflect therapeutic interpersonal relationships between health care professionals and patients in the acute care setting. This study found that therapeutic listening, responding to patient emotions and unmet needs, and patient centeredness were key characteristics of strategies for improving therapeutic interpersonal relationships.

  14. Generalizations of Wiener polarity index and terminal Wiener index

    CERN Document Server

    Ilic, Aleksandar

    2011-01-01

    In theoretical chemistry, distance-based molecular structure descriptors are used for modeling physical, pharmacologic, biological and other properties of chemical compounds. We introduce a generalized Wiener polarity index $W_k (G)$ as the number of unordered pairs of vertices $\\{u, v\\}$ of $G$ such that the shortest distance $d (u, v)$ between $u$ and $v$ is $k$. For $k = 3$, we get standard Wiener polarity index. Furthermore, we generalize the terminal Wiener index $TW_k (G)$ as the sum of distances between all pairs of vertices of degree $k$. For $k = 1$, we get standard terminal Wiener index. In this paper we describe a linear time algorithm for computing these indices for trees and partial cubes, and characterize extremal trees maximizing the generalized Wiener polarity index and generalized terminal Wiener index among all trees of given order $n$.

    Background: Whole-body magnetic resonance angiography (WBMRA) permits noninvasive vascular assessment, which can be utilized in epidemiological studies. Purpose: To assess the relation between a low ankle brachial index (ABI) and high-grade stenoses in the pelvic and leg arteries in the elderly. Material and Methods: WBMRA was performed in a population sample of 306 subjects aged 70 years. The arteries below the aortic bifurcation were graded after the most severe stenosis according to one of three grades: 0-49% stenosis, 50-99% stenosis, or occlusion. ABI was calculated for each side. Results: There were assessable WBMRA and ABI examinations in 268 (right side), 265 (left side), and 258 cases (both sides). At least one >=50% stenosis was found in 19% (right side), 23% (left side), and 28% (on at least one side) of the cases. The corresponding prevalences for ABI <0.9 were 4.5%, 4.2%, and 6.6%. An ABI cut-off value of 0.9 resulted in a sensitivity, specificity, and positive and negative predictive value of 20%, 99%, 83%, and 84% on the right side, and 15%, 99%, 82%, and 80% on the left side, respectively, for the presence of a >= 50% stenosis in the pelvic or leg arteries. Conclusion: An ABI <0.9 underestimates the prevalence of peripheral arterial occlusive disease in the general elderly population

  16. Applied Parallel Metadata Indexing

    2012-08-01

    The GPFS Archive is parallel archive is a parallel archive used by hundreds of users in the Turquoise collaboration network. It houses 4+ petabytes of data in more than 170 million files. Currently, users must navigate the file system to retrieve their data, requiring them to remember file paths and names. A better solution might allow users to tag data with meaningful labels and searach the archive using standard and user-defined metadata, while maintaining security. last summer, I developed the backend to a tool that adheres to these design goals. The backend works by importing GPFS metadata into a MongoDB cluster, which is then indexed on each attribute. This summer, the author implemented security and developed the user interfae for the search tool. To meet security requirements, each database table is associated with a single user, which only stores records that the user may read, and requires a set of credentials to access. The interface to the search tool is implemented using FUSE (Filesystem in USErspace). FUSE is an intermediate layer that intercepts file system calls and allows the developer to redefine how those calls behave. In the case of this tool, FUSE interfaces with MongoDB to issue queries and populate output. A FUSE implementation is desirable because it allows users to interact with the search tool using commands they are already familiar with. These security and interface additions are essential for a usable product.

    2005-06-01

    The glycaemic index (GI) concept was originally introduced to classify different sources of carbohydrate (CHO)-rich foods, usually having an energy content of >80 % from CHO, to their effect on post-meal glycaemia. It was assumed to apply to foods that primarily deliver available CHO, causing hyperglycaemia. Low-GI foods were classified as being digested and absorbed slowly and high-GI foods as being rapidly digested and absorbed, resulting in different glycaemic responses. Low-GI foods were found to induce benefits on certain risk factors for CVD and diabetes. Accordingly it has been proposed that GI classification of foods and drinks could be useful to help consumers make 'healthy food choices' within specific food groups. Classification of foods according to their impact on blood glucose responses requires a standardised way of measuring such responses. The present review discusses the most relevant methodological considerations and highlights specific recommendations regarding number of subjects, sex, subject status, inclusion and exclusion criteria, pre-test conditions, CHO test dose, blood sampling procedures, sampling times, test randomisation and calculation of glycaemic response area under the curve. All together, these technical recommendations will help to implement or reinforce measurement of GI in laboratories and help to ensure quality of results. Since there is current international interest in alternative ways of expressing glycaemic responses to foods, some of these methods are discussed.

    2014-01-01

    Communication issues are extensively considered a topic of high interest for improving the efficacy of the therapeutic act. This article aimed to overview several issues of therapeutic communication relevant for improving quality of care. A number of 15 bibliographic resources on these topics published in peer-reviewed journals between 1975 and 2010, and indexed in PubMed, ProQuest and EBSCO databases were examined, to seek for evidence regarding these data. Results highlight a number of communication problems commonly reported in the literature, such as the lack of physician communicational skills or their deterioration, the persistence of an asymmetric therapeutic communicational model, communication obstacles brought by the disease itself or by several variables pertaining to the patient, including specific demographic and psychological contexts. Equally, literature reports ways of improving therapeutic communication, such as optimizing the clinical interview, better time management techniques or assertiveness. Integration of communication training in the bio-psycho-social model of care and monitoring parameters like adherence and quality of life as tools reflecting also a good therapeutic communication can be valuable future approaches of obtaining better results in this area.

    No valid tools exist for evaluating the prognosis in the short and medium term after hospital discharge of patients with COPD. Our hypothesis was that a new index based on the CODEX (comorbidity, obstruction, dyspnea, and previous severe exacerbations) index can accurately predict mortality, hospital readmission, and their combination for the period from 3 months to 1 year after discharge in patients hospitalized for COPD. A multicenter study of patients hospitalized for COPD exacerbations was used to develop the CODEX index, and a different patient cohort was used for validation. Comorbidity was measured using the age-adjusted Charlson index, whereas dyspnea, obstruction, and severe exacerbations were calculated according to BODEX (BMI, airfl ow obstruction, dyspnea, and previous severe exacerbations) thresholds. Information about mortality and readmissions for COPD or other causes was collected at 3 and 12 months after hospital discharge. Two sets of 606 and 377 patients were included in the development and validation cohorts, respectively. The CODEX index was associated with mortality at 3 months ( P CODEX C statistics were superior to those of the BODEX, DOSE (dyspnea, airfl ow obstruction, smoking status, and exacerbation frequency), and updated ADO (age, dyspnea, and airfl ow obstruction) indexes. The CODEX index was a useful predictor of survival and readmission at both 3 months and 1 year after hospital discharge for a COPD exacerbation, with a prognostic capacity superior to other previously published indexes.

  20. A Novel Topological Index for the Studies on Structure-Properties of Alkanes

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    A novel topological index derived from eccentric connectivity index has been proposed. The new topological index and eccentric connectivity index were correlated with eight physical properties such as the boiling point, critical temperature, critical pressure, critical volume, evaporation heat, density, heat capaci- ty, surface tension, and three thermodynamic properties such as standard enthalpy, standard entropy and standard formation free energy of alkanes. A series of empiric equations for calculating the properties were obtained. Correlation coefficients of nine properties were more than 0. 99 . Regression analysis and calcula- tion results indicated that the topological indices were well correlated with the physico-chemical properties of alkanes, and the novel topological index was far superior to eccentric connectivity index in the correlation.

    2011-01-01

    The Harary index of a graph $G$ is recently introduced topological index, defined on the reverse distance matrix as $H(G)=\\sum_{u,v \\in V(G)}\\frac{1}{d(u,v)}$, where $d(u,v)$ is the length of the shortest path between two distinct vertices $u$ and $v$. We present the partial ordering of starlike trees based on the Harary index and we describe the trees with the second maximal and the second minimal Harary index. In this paper, we investigate the Harary index of trees with $k$ pendent vertices and determine the extremal trees with maximal Harary index. We also characterize the extremal trees with maximal Harary index with respect to the number of vertices of degree two, matching number, independence number, domination number, radius and diameter. In addition, we characterize the extremal trees with minimal Harary index and given maximum degree. We concluded that in all presented classes, the trees with maximal Harary index are exactly those trees with the minimal Wiener index, and vice versa.

There is a growing hope that the prevention of fever in stroke will improve outcome and that hypothermia may be a therapeutic option for the treatment of stroke. Body temperature...... is directly related to stroke severity and outcome, and fever after stroke is associated with substantial increases in morbidity and mortality. Normalisation of temperature in acute stroke by antipyretics is generally recommended, although there is no direct evidence to support this treatment.

To these questions the intervention seeks to answer retracing some of the highlights of almost three years of therapeutic work with a young woman and her family.

  4. Two concepts of therapeutic optimism

    Science.gov (United States)

    Jansen, Lynn A

    2011-01-01

    Researchers and ethicists have long been concerned about the expectations for direct medical benefit expressed by participants in early phase clinical trials. Early work on the issue considered the possibility that participants misunderstand the purpose of clinical research or that they are misinformed about the prospects for medical benefit from these trials. Recently, however, attention has turned to the possibility that research participants are simply expressing optimism or hope about their participation in these trials. The ethical significance of this therapeutic optimism remains unclear. This paper argues that there are two distinct phenomena that can be associated with the term ‘therapeutic optimism’—one is ethically benign and the other is potentially worrisome. Distinguishing these two phenomena is crucial for understanding the nature and ethical significance of therapeutic optimism. The failure to draw a distinction between these phenomena also helps to explain why different writers on the topic often speak past one another. PMID:21551464

    Several classes of drugs have been associated with an increased risk of cardiovascular disease and occurrence of arrhythmias potentially involved in sudden deaths in chronic users even at therapeutic doses. The study presented herein focuses on pathological changes involving the heart possibly due to methadone use. 60 cases were included in the study in total and were divided into three groups (therapeutic methadone users: 20 cases, recreational methadone users: 20 cases, and sudden death group in subjects who had never taken methadone: 20 cases). Autopsies, histology, biochemistry and toxicology were performed in all cases. Macroscopic and microscopic investigation results in therapeutic methadone users were similar to those observed in sudden, unexpected deaths in non-methadone users. In recreational methadone consumers, macroscopic and microscopic examination of the heart failed to provide results consistent with acute or chronic myocardial or coronary damage, thereby corroborating the hypothesis of death most likely following respiratory depression.

    2013-12-01

    Biosurfactants have recently emerged as promising molecules for their structural novelty, versatility, and diverse properties that are potentially useful for many therapeutic applications. Mainly due to their surface activity, these molecules interact with cell membranes of several organisms and/or with the surrounding environments, and thus can be viewed as potential cancer therapeutics or as constituents of drug delivery systems. Some types of microbial surfactants, such as lipopeptides and glycolipids, have been shown to selectively inhibit the proliferation of cancer cells and to disrupt cell membranes causing their lysis through apoptosis pathways. Moreover, biosurfactants as drug delivery vehicles offer commercially attractive and scientifically novel applications. This review covers the current state-of-the-art in biosurfactant research for therapeutic purposes, providing new directions towards the discovery and development of molecules with novel structures and diverse functions for advanced applications.

    Full Text Available Bone-seeking therapeutic radiopharmaceuticals are utilized on the basis of the radionuclide?s particulate emissions (primarily low to intermediate beta emission. The requirements therefore are different from those of bone imaging agents that consist mainly of short-lived single photon emitters. Lately, the therapeutic bone seeking radiopharmaceuticals have attained increasing importance due to their potential role in alleviating pain from osseous metastases in cancer patients, for the treatment of joint pain resulting from inflamed synovium (radiosynoviorthesis, or radiosynovectomy, or from various other forms of arthritic disease. There is, however, a paucity of published data on the bio-pharmacokinetics of these agents when used following intravenous administration for bone pain palliation. This paper will briefly review and summarize the presently available chemical and biopharmacokinetic information on the various clinically approved as well as experimental bone-localizing therapeutic radiopharmaceuticals, and make projections on their clinical application for the treatment of primary/metastatic cancer in bone.

    The bioaccumulation and biotransformation of toxaphene was examined in the food webs of Lake Superior and Siskiwit Lake (Isle Royale) using congener specific analysis as well as stable isotope ratios of carbon and nitrogen to characterize food webs. Toxaphene concentrations (calculated using technical toxaphene) in lake trout (Salvelinus namaycush) from the western basin of Lake Superior (N = 95) averaged (±SD) 889 ± 896 ng/g wet wt and 60 ± 34 ng/g wet wt in Siskiwit Lake. Major congeners in lake trout were B8-789 (P38), B8-2226 (P44), B9-1679 (P50), and B9-1025 (P62). Toxaphene concentrations were found to vary seasonally, especially in lower food web organisms in Lake Superior and to a lesser extent in Siskiwit Lake. Toxaphene concentrations declined significantly in lake herring (Coregonus artedii), rainbow smelt (Omerus mordax), and slimy sculpin (Cottus cognatus) as well as in zooplankton (> 102 &mn;m) and Mysis (Mysis relicta) between May and October. The seasonal variation may reflect seasonal shifts in the species abundance within the zooplankton community. Trophic magnification factors (TMF) derived from regressions of toxaphene congener concentrations versus δ15N were > 1 for most octa- and nonachlorobornanes in Lake Superior except B8-1413 (P26) and B9-715. Log bioaccumulation factors (BAFs) for toxaphene congeners in lake trout (ng/g lipid/ng/L dissolved) ranged from 4.54 to 9.7 and were significantly correlated with log octanol-water partition coefficients. TMFs observed for total toxaphene and congener B9-1679 in Lake Superior were similar to those in Arctic lakes, as well as to previous studies in the Great Lakes, which suggests that the bioaccumulation behavior of toxaphene is similar in pelagic food webs of large, cold water systems. However, toxaphene concentrations were lower in lake trout from Siskiwit Lake and lakes in northwestern Ontario than in Lake Superior possibly because of shorter food chains and greater reliance on zooplankton or

  9. Therapeutics for Equine Endocrine Disorders.

    Durham, Andy E

    2017-04-01

    Equine endocrine disease is commonly encountered by equine practitioners. Pituitary pars intermedia dysfunction (PPID) and equine metabolic syndrome (EMS) predominate. The most logical therapeutic approach in PPID uses dopamine agonists; pergolide mesylate is the most common. Bromocryptine and cabergoline are alternative drugs with similar actions. Drugs from other classes have a poor evidence basis, although cyproheptadine and trilostane might be considered. EMS requires management changes as the primary approach; reasonable justification for use of drugs such as levothyroxine and metformin may apply. Therapeutic options exist in rare cases of diabetes mellitus, diabetes insipidus, hyperthyroidism, and critical illness-related corticosteroid insufficiency. Copyright © 2016 Elsevier Inc.

    An innovative practice, therapeutic touch has been used for around ten years in the treatment of eating disorders. Delivered by nurse clinicians having received specific training, this approach is based on nursing diagnoses which identify the major symptoms of this pathology. The support is built around the body and its perceptions. Through the helping relationship, it mobilises the patient's resources to favour a relationship of trust, a letting-go, physical, psychological and emotional relaxation, and improves the therapeutic alliance.

    Full Text Available This article analysed the different narratives implied in Philemon by utilising the narrative therapeutic approach, as developed by Epston and White (1990. A dominant narrative (the harsh treatment of slaves in the early Christian environment and a challenging narrative (a more humane conduct of slaves were clearly distinguished. The article showed Paul’s attempt to bridge the gap between these two narratives by using certain pointers, possibly taken from mystery religions and Jesus’ example. In conclusion, the narrative therapeutic approach proved to be a new and unique way of looking at Philemon’s narrative world.

    Antle, Emily Amy

    2010-12-01

    Many oncology practices treat patients with benign and malignant hematologic diagnoses. As a result, oncology nurses often are required to care for these patients. One common procedure nurses perform is therapeutic phlebotomy, where about 500 ml of blood is removed through a large-bore needle over 15-30 minutes. The procedure is ordered as a treatment for hereditary hemochromatosis, polycythemia vera, and secondary polycythemia. Before initiating the procedure, nurses must be aware of a patient's diagnosis, baseline hemoglobin, hematocrit, ferritin, and therapeutic end points. Reviewing these diagnoses will help nurses understand why phlebotomy is an important part of treatment.

  14. Can linear superiorization be useful for linear optimization problems?

    Science.gov (United States)

    Censor, Yair

    2017-04-01

    Linear superiorization (LinSup) considers linear programming problems but instead of attempting to solve them with linear optimization methods it employs perturbation resilient feasibility-seeking algorithms and steers them toward reduced (not necessarily minimal) target function values. The two questions that we set out to explore experimentally are: (i) does LinSup provide a feasible point whose linear target function value is lower than that obtained by running the same feasibility-seeking algorithm without superiorization under identical conditions? (ii) How does LinSup fare in comparison with the Simplex method for solving linear programming problems? Based on our computational experiments presented here, the answers to these two questions are: ‘yes’ and ‘very well’, respectively.

    Savoie, F H; Field, L D; Atchinson, S

    2001-07-01

    Anterosuperior instability of the shoulder may occur from a variety of pathologic lesions. We describe a specific entity, the SLAC (superior labrum, anterior cuff) lesion that involves an association of anterior-superior labral tear with a partial supraspinatus tear. We retrospectively isolated a group of 40 patients with this lesion. The presenting complaints, physical examination findings, surgical findings, and results were isolated. Overhead activities were the most common etiology; load and shift instability testing and whipple rotator cuff testing were the most common physical examination findings. Surgical repair was successful in 37 of the 40 patients. The SLAC lesion is a definable clinical entity with predictable history, examination, surgical pathology, and satisfactory results from surgery.

  16. Superior gluteal nerve entrapment between two bellies of piriformis muscle

    Yadav Y

    2010-12-01

    Full Text Available A double belly composition of piriformis muscle with superior gluteal nerve entrapment between the two muscle masses was detected. Piriformis muscle and its relation to sciatic nerve has been suggested as a cause of piriformis syndrome. Patients suffering from buttock pain are most often diagnosed as having piriformis syndrome, where anatomical variation of the piriformis is an important contributor. The present variation showed two distinct bellies of piriformis muscle. Interestingly the superior gluteal nerve was interposed between the two bellies. Such incidental findings on cadavers may help the clinicians to establish a rare yet important cause of piriformis syndrome. Furthermore, such observations are also relevant to the radiologists while interpreting MRI scans in cases of undiagnosed chronic gluteal pain.

    Pittau, Gabriella; Sànchez-Cabùs, Santiago; Laurenzi, Andrea; Gelli, Maximiliano; Cunha, Antonio Sa

    2015-12-01

    Pancreaticoduodenectomy (PD) is considered one of the most challenging abdominal operations for several reasons, including the anatomy, which is surrounded by vital vascular structures and also because of the serious complications that are possible in the postoperative period. Nowadays, thanks to the development of minimally invasive surgery and improvement of patients' selection, laparoscopic pancreatic resections have been proven to be technically feasible and safe especially in the case of left pancreatectomies. More recently, many series of laparoscopic PD for adenocarcinoma have been published demonstrating the feasibility of this technique. In pancreatic cancer, the advantage of superior mesenteric artery "first approach" is already known to achieve an oncological resection. The purpose of this video is to describe the different technical aspects of the laparoscopic superior mesenteric artery first approach in the right posterior fashion.

    Access to the superior mid-orbit is required for procedures on the levator muscle in the correction of upper eyelid ptosis and in surgery aimed at local lesions in this region. The purpose with this human cadaver study was to clarify the anatomical substrate for a surgical approach to the levator muscle and the upper mid-orbit structures, in which the orbital septum and the retroseptal fat pad is not harmed during surgery. Macro-anatomical dissections and histological examinations were performed on five human orbits from three formalin embalmed cadaver heads. It was found that the orbital septum extends posteriorly from its junction with the levator aponeurosis. This posterior continuation of the orbital septum encloses the superior orbital fat pad and separates this from the anterior surface of the levator muscle. In between the orbital septum and the levator, there is a dissection space that provides a minimal invasive access corridor to the structures in the upper mid-orbit.

    The recent identification of highly superior autobiographical memory (HSAM) raised the possibility that there may be individuals who are immune to memory distortions. We measured HSAM participants' and age- and sex-matched controls' susceptibility to false memories using several research paradigms. HSAM participants and controls were both susceptible to false recognition of nonpresented critical lure words in an associative word-list task. In a misinformation task, HSAM participants showed higher overall false memory compared with that of controls for details in a photographic slideshow. HSAM participants were equally as likely as controls to mistakenly report they had seen nonexistent footage of a plane crash. Finding false memories in a superior-memory group suggests that malleable reconstructive mechanisms may be fundamental to episodic remembering. Paradoxically, HSAM individuals may retrieve abundant and accurate autobiographical memories using fallible reconstructive processes.

  20. Genomes for jeans: cotton genomics for engineering superior fiber.

    Mansoor, Shahid; Paterson, Andrew H

    2012-10-01

    Twenty years ago, scientists predicted that better understanding of fiber development would lead to novel ways to engineer superior cotton fiber. Advances in genetic resources, DNA markers, DNA sequence information, and gene expression data have indeed provided new insights into fiber initiation, elongation and maturation. Many exciting applications of this knowledge offer the potential to select better cotton genotypes more effectively in mainstream breeding programs or engineer genotypes with improved agronomic and/or quality traits. Here, we discuss recent progress in understanding genes involved in fiber development, and their regulation and manipulation to engineer improved fibers. Better understanding of quantitative trait loci/gene interactions that influence fiber quality and yield may help to tailor superior cotton genotypes to diverse environments.

    Tullio phenomenon refers to eye movements induced by sound.(1) This unusual examination finding may be seen in superior semicircular canal dehiscence (SSCD) syndrome.(2) This disorder is due to absent bone over the superior semicircular canal (figure). Patients complain of dizziness triggered by loud sound, aural fullness, autophony, and pulsatile tinnitus. When Tullio phenomenon exists in SSCD syndrome, the patient develops a mixed vertical-torsional nystagmus in which the slow phase rotates up and away from the affected ear (video on the Neurology® Web site at Neurology.org). This pattern of nystagmus aligns in the plane of the dehiscent semicircular canal and is due to excitation of its afferent nerves.

    The suggestion that the colloidal-dispersion-gel (CDG) process is superior to normal polymer flooding is misleading and generally incorrect. Colloidal dispersion gels, in their present state of technological development, should not be advocated as an improvement to, or substitute for, polymer flooding. Gels made from aluminum-citrate crosslinked polyacrylamides can act as conventional gels and provide effective conformance improvement in treating some types of excess water production problems if sound scientific and engineering principles are respected.

    Gluteal artery aneurysms are rare and often secondary to pelvic fractures, blunt or penetrating trauma. We describe a case of a superior gluteal artery pseudoaneurysm that presented as back pain with numbness and weakness of the lower extremities. Diagnosis was confirmed by color Doppler sonography and angiography. A proximal and distal control was obtained over the aneurysm neck via coil embolization with excellent hemostasis within the pseudoaneurysm and maintenance of perfusion to the left pelvis. (orig.)

    The superior gluteal nerve is responsible for innervating the gluteus medius, gluteus minimus and tensor fascia latae muscles, all of which can be injured during surgical procedures. We describe an ultrasound-guided approach to block the superior gluteal nerve which allowed us to provide efficient analgesia and anesthesia for two orthopedic procedures, in a patient who had significant risk factors for neuraxial techniques and deep peripheral nerve blocks. An 84-year-old female whose regular use of clopidogrel contraindicated neuraxial techniques or deep peripheral nerve blocks presented for urgent bipolar hemiarthroplasty in our hospital. Taking into consideration the surgical approach chosen by the orthopedic team, we set to use a combination of general anesthesia and superficial peripheral nerve blocks (femoral, lateral cutaneous of thigh and superior gluteal nerve) for the procedure. A month and a half post-discharge the patient was re-admitted for debriding and correction of suture dehiscence; we performed the same blocks and light sedation. She remained comfortable in both cases, and reported no pain in the post-operative period. Deep understanding of anatomy and innervation empowers anesthesiologists to solve potentially complex cases with safer, albeit creative, approaches. The relevance of this block in this case arises from its innervation of the gluteus medius muscle and posterolateral portion of the hip joint. To the best of our knowledge, this is the first report of an ultrasound-guided superior gluteal nerve block with an analgesic and anesthetic goal, which was successfully achieved.

    2012-04-01

    Information Superiority generated through proper application of Geoinformatics Information management and especially geoscience information delivery is a very delicate task. If it is carried out successfully, geoscientific data will provide the main foundation of Information Superiority. However, improper implementation of geodata generation, assimilation, distribution or storage will not only waste valuable resources like manpower or money, but could also give rise to crucial deficiency in knowledge and might lead to potentially extremely harmful disasters or wrong decisions. Comprehensive Approach, Effect Based Operations and Network Enabled Capabilities are the current buzz terms in the security regime. However, they also apply to various interdisciplinary tasks like catastrophe relief missions, civil task operations or even in day to day business operations where geo-science data is used. Based on experience in the application of geoscience data for defence applications the following procedure or tool box for generating geodata should lead to the desired information superiority: 1. Understand and analyse the mission, the task and the environment for which the geodata is needed 2. Carry out a Information Exchange Requirement between the user or customer and the geodata provider 3. Implementation of current interoperability standards and a coherent metadata structure 4. Execute innovative data generation, data provision, data assimilation and data storage 5. Apply a cost-effective and reasonable data life cycle 6. Implement IT security by focusing of the three pillar concepts Integrity, Availability and Confidentiality of the critical data 7. Draft and execute a service level agreement or a memorandum of understanding between the involved parties 8. Execute a Continuous Improvement Cycle These ideas from the IT world should be transferred into the geoscience community and applied in a wide set of scenarios.

    Full Text Available Introduction: Superior oblique split lengthening (SOSL is done for weakening of superior oblique. It corrects the superior oblique overaction (SOOA and A pattern. Its effect on the torsion of the eye is not known. We present our data on the effect of this particular procedure on torsion. Materials and Methods: We did a study of 16 patients (32 eyes who underwent bilateral SOSL and compared the disc foveal angle (DFA preoperatively and postoperatively. The split lengthening was done from 4 mm to 7 mm depending upon the overaction of superior oblique. Results: The mean age was 15.3 ± 8.4 years. Mean preoperative DFA in the right eye (RE was −3.9° and in the left eye (LE was −2.9°. Mean postoperative DFA in RE was 0.2° and in LE was 0.9°. The mean change in the DFA for RE was 4.1° ± 1.3° and for LE was 3.8° ± 1.2°. All the patients were aligned horizontally within 6 prism diopter and no pattern and no diplopia postoperatively. The A pattern was corrected in all the patient postsurgery. For each mm of surgery, an improvement of 0.8° was seen in the DFA. Conclusion: We report the effect of SOSL on torsion. The SOSL reduces intorsion postsurgery and is, therefore, a valuable procedure in SOOA where both pattern and in torsion needs to be corrected.

    The superior parathyroid gland is known to be almost constant in its location under the false thyroid capsule. Could it be a landmark to point to the site of incision of the false thyroid capsule and find the plane of the recurrent laryngeal nerve (RLN) during thyroidectomy? The study included 48 patients with benign goiter scheduled for hemithyroidectomy or total thyroidectomy; there were 16 cases of solitary thyroid nodules, 27 cases of multinodular goiter, and 5 cases of toxic goiter. This study included 80 lobectomies. All patients showed no evidence of postoperative RLN palsy, bleeding, or hypoparathyroidism. The superior parathyroid gland was consistently found within the false capsule in all cases, whereas the inferior parathyroid was found within the same layer in 64 sides (80%). The described approach can accurately guide dissection between true and false capsules of the thyroid to reach and preserve both the RLN and the superior parathyroid gland. © 2017 Wiley Periodicals, Inc.

    Introduction: The main purpose of this study is to determine the radiological incidence of Superior (SSCD) and Posterior Semicircular Canal Dehiscence (PSCD) and to compare radiologic SSCD to the incidence of this condition on cadaver specimen. We have also analysed the relation between the ossification state of the semicircular canals and the degree of mastoid pneumatization and integrity of Tegmen Tympani. Material and methods: Temporal bones have been investigated by means of CT scan on patients and direct observation on cadaver specimen, respectively. Results: 604 ears and 160 cadaver temporal bones have been investigated by means of CT scan and direct observation, respectively. 3.6% and 0.3% of the studied ears had SSCD and PSCD, respectively, on CT scan. Only 0.6% of the cadaver specimen ears did have anatomical SSCD. Degree of pneumatization of the mastoid bone is related to the mean thickness of bone overlying the Superior and Posterior Semicircular Canal. Radiological absence of Tegmen Tympani is more frequent in ears that also have radiologic SSCD. Conclusion: CT scanning gives higher incidence figures of SSCD than anatomical studies, 3.6% vs. 0.6%. We also found a 0.6% incidence of radiological PSCD in the studied ears. There is a direct relation between the degree of ossification of Superior and Posterior Semicircular Canal and certain temporal bone anatomic features: temporal bone pneumatization and absence/presence of Tegmen Tympani or Antri.

The superiority of composite sheep were obtained in good and limited feed condition. Lamb growth parameters were also affected by feed condition, parity, sex, and rearing type.

  1. Superior metallic alloys through rapid solidification processing (RSP) by design

    Energy Technology Data Exchange (ETDEWEB)

    Flinn, J.E. [Idaho National Engineering Laboratory, Idaho Falls, ID (United States)

    1995-05-01

    Rapid solidification processing using powder atomization methods and the control of minor elements such as oxygen, nitrogen, and carbon can provide metallic alloys with superior properties and performance compared to conventionally processing alloys. Previous studies on nickel- and iron-base superalloys have provided the baseline information to properly couple RSP with alloy composition, and, therefore, enable alloys to be designed for performance improvements. The RSP approach produces powders, which need to be consolidated into suitable monolithic forms. This normally involves canning, consolidation, and decanning of the powders. Canning/decanning is expensive and raises the fabrication cost significantly above that of conventional, ingot metallurgy production methods. The cost differential can be offset by the superior performance of the RSP metallic alloys. However, without the performance database, it is difficult to convince potential users to adopt the RSP approach. Spray casting of the atomized molten droplets into suitable preforms for subsequent fabrication can be cost competitive with conventional processing. If the fine and stable microstructural features observed for the RSP approach are preserved during spray casing, a cost competitive product can be obtained that has superior properties and performance that cannot be obtained by conventional methods.

    Full Text Available Background: The stomatitis sub-prosthesis is one of the most frequent changes in hard palate mucous membrane in patients with mucous-supported dental prosthesis. It can be caused by multiple factors, which makes its study and prognosis more difficult. Objective: To describe the occurrence of stomatitis sub-prosthesis and its causes in patients with superior dental prosthesis. Method: Descriptive study including all the patients with superior dental prosthesis examined in the odontology consultation “Barrio Adentro” in the state of Miranda, Venezuela, from November, 2005 to March, 2006. The analysed variables were: age, sex, stomatitis level, teeth brushing frequency, prosthesis condition and use, palate mucous condition and frequency of odontology consultations. Results: 89 patients were attended, more 50% of them had superior dental prosthesis and presented stomatitis sub-prosthesis; the group between 35 and 59 years was the most affected, mainly females. Sub-prosthesis stomatitis type II was the most common and the main causes included constant use of the prosthesis and loose prosthesis. Buccal hygiene was not adequate in these patients. Most of them declared never attending to the dentist, or just when presenting some particular problem. Conclusion: Stomatitis prevalence was related with incorrect hygiene habits and lack of knowledge; it shows the importance of performing educative tasks to reduce this disease incidence.

    Water quality of streams tributary to Lakes Superior and Michigan was analyzed for 142 stations on 99 streams tributary to Lake Superior and 83 stations on 56 streams tributary to Lake Michigan during 1962-65. Concentrations of aluminum, copper, and iron were not affected greatly by flow or season. Magnesium, calcium, chlorides, total alkalinity, total hardness, and conductivity varied with the flow, temperature, and season; the lowest values were during the spring runoff and heavy rains, and the highest were during low water in late summer and the colder periods of winter. Concentrations of nitrate, silica, and sulfates were lowest in the spring and summer. Concentrations of tanninlike and ligninlike compounds were highest during the spring runoff and other high-water periods, and were lowest during freezeup when surface runoff was minimal. The pH values were highest from June to September and lowest during the spring runoff. Phenolphthalein alkalinity was detected primarily in the summer and coincided occasionally with low flows just before the spring thaw. Total hardness usually was lower in streams tributary to Lake Superior than in streams tributary to Lake Michigan. The total hardness was higher in the streams in Wisconsin than in the streams in Michigan along the west shore of Lake Michigan. It was lowest in the northernmost streams. The water quality of the streams in an area was related to the geological characteristics of the land.

    Since the ability to degrade lignin with one kind of white-rot fungi or bacteria was very limited, superior mixed flora's ability to degrade lignin was investigated by an orthogonal experiment in this paper. The results showed that superior mixed flora reinforced the ability to degrade lignin, the degradation rates of both sample 9 and 10 were beyond 80% on the day 9. The cooperation between lignin peroxidase(LiP), Mn-dependent peroxidase(MnP) and laccase (Lac) for lignin degradation was also studied. By examining the activities of three enzymes produced by superior mixed flora, it was found that Lac was a key enzyme in the process of biological degradation of lignin but Lip was not; the enzyme activity ratios of Lac/MnP and Lac/LiP were significantly correlative with the degradation rate of lignin at the 0.01 level; and the ratio of MnP/LiP was an important factor affecting the degradation rate of lignin.

    Auditory speech perception can be altered by concurrent visual information. The superior temporal cortex is an important combining site for this integration process. This area was previously found to be sensitive to audiovisual congruency. However, the direction of this congruency effect (i.e., stronger or weaker activity for congruent compared to incongruent stimulation) has been more equivocal. Here, we used fMRI to look at the neural responses of human participants during the McGurk illusion--in which auditory /aba/ and visual /aga/ inputs are fused to perceived /ada/--in a large homogenous sample of participants who consistently experienced this illusion. This enabled us to compare the neuronal responses during congruent audiovisual stimulation with incongruent audiovisual stimulation leading to the McGurk illusion while avoiding the possible confounding factor of sensory surprise that can occur when McGurk stimuli are only occasionally perceived. We found larger activity for congruent audiovisual stimuli than for incongruent (McGurk) stimuli in bilateral superior temporal cortex, extending into the primary auditory cortex. This finding suggests that superior temporal cortex prefers when auditory and visual input support the same representation.

    To evaluate efficacy of Tiamuline in mycoplasmosis of chickens and turkeys under controlled field conditions 2 prophylactical and 3 therapeutical trials were conducted. The compound was administered via drinking water for 3 days in comparison to Tylosin tartrate. In both prophylactical and therapeutical tests, Tiamuline showed a superior efficiacy, as measured by clinical symptoms, pathological lesions and microbiological findings. Therefore, Tiamuline can be recommended for treatment of mycoplasmosis in chickens and turkeys in a dosage of 0.025% and in a dosage of 0.0125% for prophylaxis in flocks at risk.

    This paper defines and discusses a glass dispersion formula that is adaptive. The formula exhibits superior convergence with a minimum number of coefficients. Using this formula we rationalize the correction of chromatic aberration per spectrum order. We compare the formula with the Sellmeier and Buchdahl formulas for glasses in the Schott catalogue. The six coefficient adaptive formula is found to be the most accurate with an average maximum index of refraction error of 2.91 × 10(-6) within the visible band.

In most cases, these diseases have a bad prognosis without treatment. Therapeutic apheresis in combination with immunosuppressive therapies has led to a steady increase in survival rates over the last 35 years. Here we provide an overview of the most important pathogenic aspects indicating that therapeutic apheresis can be a supportive therapy in some systemic autoimmune diseases, such as systemic lupus erythematosus, antiphospholipid syndrome, rheumatoid arthritis, and inflammatory eye disease. With the introduction of novel and effective biologic agents, therapeutic apheresis is indicated only in severe cases, such as in rapid progression despite immunosuppressive therapy and/or biologic agents, and in patients with renal involvement, acute generalized vasculitis, thrombocytopenia, leucopenia, pulmonary, cardiac, or cerebral involvement. In mild forms of autoimmune disease, treatment with immunosuppressive therapies and/or biologic agents seems to be sufficient. The prognosis of autoimmune diseases with varying organ manifestations has improved considerably in recent years, due in part to very aggressive therapy schemes.

    We study the Boolean satisfiability problem (SAT) restricted on input formulas for which there are linear arithmetic constraints imposed on the indices of variables occurring in the same clause.This can be seen as a structural counterpart of Schaefer's dichotomy theorem which studies the SAT problem with additional constraints on the assigned values of variables in the same clause.More precisely,let k-SAT(m,A) denote the SAT problem restricted on instances of k-CNF formulas,in every clause of which the indices of the last k-m variables are totally decided by the first m ones through some linear equations chosen from A.For example,if A contains i3 =i1+2i2 and i4 =i2-i1 + 1,then a clause of the input to 4-SAT(2,A) has the form yi1∨yi2∨yi1+2i2∨yi2-i1+1,with yi being xi or (xi).We obtain the following results:1) If m ≥2,then for any set A of linear constraints,the restricted problem k-SAT(m,A) is either in P or NP-complete assuming P ≠ NP.Moreover,the corresponding #SAT problem is always #P-complete,and the MAx-SAT problem does not allow a polynomial time approximation scheme assuming P ≠ NP.2) m =1,that is,in every clause only one index can be chosen freely.In this case,we develop a general framework together with some techniques for designing polynomial-time algorithms for the restricted SAT problems.Using these,we prove that for any A,#2-SAT(1,A) and MAX-2-SAT(1,A) are both polynomial-time solvable,which is in sharp contrast with the hardness results of general #2-SAT and MAX-2-SAT.For fixed k≥ 3,we obtain a large class of non-trivial constraints A,under which the problems k-SAT(1,A),#k-SAT(1,A)and MAx-k-SAT(1,A) can all be solved in polynomial time or quasi-polynomial time.

    Abstract The Pemberton Happiness Index (PHI) is a recently developed integrative measure of well-being that includes components of hedonic, eudaimonic, social, and experienced well-being. The PHI has been validated in several languages, but not in Portuguese. Our aim was to cross-culturally adapt the Universal Portuguese version of the PHI and to assess its psychometric properties in a sample of the Brazilian population using online surveys. An expert committee evaluated 2 versions of the PHI previously translated into Portuguese by the original authors using a standardized form for assessment of semantic/idiomatic, cultural, and conceptual equivalence. A pretesting was conducted employing cognitive debriefing methods. In sequence, the expert committee evaluated all the documents and reached a final Universal Portuguese PHI version. For the evaluation of the psychometric properties, the data were collected using online surveys in a cross-sectional study. The study population included healthcare professionals and users of the social network site Facebook from several Brazilian geographic areas. In addition to the PHI, participants completed the Satisfaction with Life Scale (SWLS), Diener and Emmons’ Positive and Negative Experience Scale (PNES), Psychological Well-being Scale (PWS), and the Subjective Happiness Scale (SHS). Internal consistency, convergent validity, known-group validity, and test–retest reliability were evaluated. Satisfaction with the previous day was correlated with the 10 items assessing experienced well-being using the Cramer V test. Additionally, a cut-off value of PHI to identify a “happy individual” was defined using receiver-operating characteristic (ROC) curve methodology. Data from 1035 Brazilian participants were analyzed (health professionals = 180; Facebook users = 855). Regarding reliability results, the internal consistency (Cronbach alpha = 0.890 and 0.914) and test–retest (intraclass correlation coefficient = 0.814) were

    Full Text Available Oral cancer cavity (OCC is associated with high incidence of loco-regional recurrences, which account for the majority of treatment failures post-surgery and radiotherapy. The time-course of relapse manifestation and metastasis are unpredictable. Relapsed OCC represents a major clinical challenge in part due to their aggressive and invasive behaviors. Chemotherapy remains the only option for advanced OCC whenever salvage surgery or re-irradiation is not feasible, but its efficacy is limited as a result of the drug resistance development. Alternatives to use of different permutations of standard cytotoxic drugs or combinations with modulators of drug resistance have led to incremental therapeutic benefits. The introduction of targeted agents and biologics against selective targets that drive cancer progression has opened-up optimism to achieve superior therapeutic activity and overcome drug resistance because, unlike the non-selective cytotoxic, the target can be monitored at molecular levels to identify patients who can benefit from the drug. This review discusses the multifactorial aspects of clinical drug resistance and emerging therapeutic approaches in recurrent OCC, emphasizing recent advances in targeted therapies, immunotherapy, and potential relevance of new concepts such as epithelial-mesenchymal transition and cancer stem cell hypothesis to drug resistance.

  17. Cardiovascular calcifications in chronic kidney disease: Potential therapeutic implications.

    Bover, Jordi; Ureña-Torres, Pablo; Górriz, José Luis; Lloret, María Jesús; da Silva, Iara; Ruiz-García, César; Chang, Pamela; Rodríguez, Mariano; Ballarín, José

    Cardiovascular (CV) calcification is a highly prevalent condition at all stages of chronic kidney disease (CKD) and is directly associated with increased CV and global morbidity and mortality. In the first part of this review, we have shown that CV calcifications represent an important part of the CKD-MBD complex and are a superior predictor of clinical outcomes in our patients. However, it is also necessary to demonstrate that CV calcification is a modifiable risk factor including the possibility of decreasing (or at least not aggravating) its progression with iatrogenic manoeuvres. Although, strictly speaking, only circumstantial evidence is available, it is known that certain drugs may modify the progression of CV calcifications, even though a direct causal link with improved survival has not been demonstrated. For example, non-calcium-based phosphate binders demonstrated the ability to attenuate the progression of CV calcification compared with the liberal use of calcium-based phosphate binders in several randomised clinical trials. Moreover, although only in experimental conditions, selective activators of the vitamin D receptor seem to have a wider therapeutic margin against CV calcification. Finally, calcimimetics seem to attenuate the progression of CV calcification in dialysis patients. While new therapeutic strategies are being developed (i.e. vitamin K, SNF472, etc.), we suggest that the evaluation of CV calcifications could be a diagnostic tool used by nephrologists to personalise their therapeutic decisions.

  18. The HLD (CalMod) index and the index question.

    Science.gov (United States)

    Parker, W S

    1998-08-01

    The malocclusion index problem arises because of the need to identify which patient's treatments will be paid for with tax dollars. Both the civilian (Medicaid) and military (Champus) programs in the United States require that "need" be demonstrated. Need is defined as "medically necessary handicapping malocclusion" in Medicaid parlance. It is defined by Champus as "seriously handicapping malocclusion." The responsible specialty organization (the AAO) first approved the Salzmann Index in 1969 for this purpose and then reversed course in 1985 and took a formal position against the use of any index. Dentistry has historically chosen a state of occlusal perfection as ideal and normal and declared that variation was not normal hence abnormal and thus malocclusion. This "ideal" composes from 1% to 2% of the population and fails all statistical standards. Many indexes have been proposed based on variations from this "ideal" and fail for that reason. They are not logical. The HLD (CalMod) Index is a lawsuit-driven modification of some 1960 suggestions by Dr. Harry L. Draker. It proposes to identify the worst looking malocclusions as handicapping and offers a cut-off point to identify them. In addition, the modification includes two situations known to be destructive to tissue and structures. As of Jan. 1, 1998, the California program has had 135,655 patients screened by qualified orthodontists using this index. Of that number, 49,537 patients have had study models made and screened by qualified orthodontists using the index. Two separate studies have been performed to examine results and to identify problems. Necessary changes have been made and guidelines produced. The index problem has proven to be very dynamic in application. The HLD (CalMod) Index has been successfully applied and tested in very large numbers. This article is published as a factual review of the situation regarding the index question and one solution in the United States.

  19. Bispectral Index Monitor

    Science.gov (United States)

    2004-01-01

    Executive Summary The objective of this analysis was to evaluate the effectiveness and cost-effectiveness of the bispectral index (BIS) monitor, a commercial device to assess the depth of anesthesia. Conventional methods to assess depth of consciousness, such as cardiovascular and pulmonary measures (e.g., heart rate, systolic/diastolic blood pressure, mean arterial pressure, respiratory rate, and level of oxygen in the blood), and clinical signs (e.g., perspiration, shedding of tears, and limb movement) are not reliable methods to evaluate the brain status of anesthetized patients. Recent progress in understanding the electrophysiology of the brain has led to the development of cerebral monitoring devices that identify changes in electrophysiologic brain activity during general anesthesia. The BIS monitor, derived from electroencephalogram (EEG) data, has been used as a statistical predictor of the level of hypnosis and has been proposed as a tool to reduce the risk of intraoperative awareness. Anesthesia that is too light can result in the recall of events or conversations that happen in the operation room. Patients have recalled explicit details of conversations that happened while under anesthesia. This awareness is frightening for patients and can lead to post-traumatic stress disorder. Conversely, anesthesia that is too deep can cause hemodynamic disturbances necessitating the use of vasoconstrictor agents, which constrict blood vessels, to maintain normal blood pressure and cardiac output. Overly deep anesthesia can also result in respiratory depression requiring respiratory assistance postoperatively. Monitoring the depth of anaesthesia should prevent intraoperative awareness and help to ensure that an exact dose of anaesthetic drugs is given to minimize adverse cardiovascular effects caused by overly large doses. Researchers have suggested that cerebral monitoring can be used to assess the depth of anesthesia, prevent awareness, and speed early recovery

    The temporo-parietal (TP) white matter connections between the inferior parietal lobule and superior temporal gyrus as part of the superior longitudinal fasciculus/arcuate fasciculus (SLF/AF) or middle longitudinal fasciculus (MdLF) have been studied in prior diffusion tensor tractography (DTT) studies. However, few studies have been focusing on the higher TP connections of the superior parietal lobule with the temporal lobe. These higher TP connections have been shown to have a role in core processes such as attention, memory, emotions, and language. Our most recent study, for the first time, hinted to the possibility of a long white matter connection interconnecting the superior parietal lobule (SPL) with the posterior temporal lobe in human brain which we call the SLF/AF TP-SPL and for a shorter abbreviation, the TP-SPL. We decided to further investigate this white matter connection using fiber assignment by continuous tracking deterministic tractography and high spatial resolution diffusion tensor imaging on 3T. Five healthy right-handed men (age range 24-37 years) were studied. We delineated the SPL connections of the SLF/AF TP bilaterally in five normal adult human brains. Using a high resolution DTT technique, we demonstrate for the first time, the trajectory of a long fiber bundle connectivity between the SPL and posterior temporal lobe, called the SLF/AF TP-SPL (or the TP-SPL), bilaterally in five healthy adult human brains. We also demonstrate the trajectory of the vertically oriented posterior TP connections, interconnecting the inferior parietal lobule (IPL) with the posterior temporal lobe (TP-IPL) in relation to the TP-SPL, arcuate fasciculus and other major language pathways. In the current study, for the first time, we categorized the TP connections into the anterior and posterior connectivity groups and subcategorized each one into the SPL or IPL connections.

  4. Geoscience indexing at petroleum abstracts

    Energy Technology Data Exchange (ETDEWEB)

    Finnegan, M.A.

    1985-01-01

    Geoscience literature received by Petroleum Abstracts Information System is indexed by Scientist with field experience. The indexing consists of relating concepts produced by the author to a controlled vocabulary used at Petroleum Abstracts. The primary emphasis of selection of the literature at Petroleum Abstracts is petroleum-related, but not petroleum restricted. Geoscience literature indexed at Petroleum Abstracts comprises the following subjects: Geology, Geochemistry, Geophysics, and Mineral Commodities. The depth of indexing attributed to each article does in fact depend on the amount of petroleum-related subject matter in the article. Once the indexing is completed, the abstract is then cut to approximately 150 words. The scientist who indexes at Petroleum Abstracts is not expected to know or remember every detail or concept ever published. But he or she is expected to be able to go to an atlas, dictionary, or any other reference material available and apply the concepts to a controlled vocabulary. This is somewhat of a restriction on scientists, but it is the only way to maintain any kind of consistency in the indexing. Successful searching of the Petroleum Abstracts Information System can be accomplished with an understanding of the indexing strategy and the importance and necessity of referencing the thesauri controlled vocabulary. It may be more time-consuming, but will certainly be more accurate in the retrieval of the information.

    The epidemic-like rise in chronic low back pain in western industrial nations is less an expression of a medical than a psychosocial phenomenon. Differentiation between acute, chronic or chronifying pain is of crucial importance for therapeutic procedures. Pain syndromes in the muscular-skeletal system tend to become chronic to a far larger extent than expected. More than 80 % of low back pain represents a functional pain syndrome and does not show any pathoanatomical correlate. Pain existing independently seems to be predestined by a somatic and psychosocial deconditioning syndrome. Those at risk of chronifying pain or those whose pain is already chronic should be given an interdisciplinary, multimodal therapeutic program. A pilot study was carried out in our clinic: multidisciplinary treatment was given to our patients (of which over 90 % belonged to stages II and III on the Gerbershagen scale) and the result was significant improvement in the measurements of pain intensity, sensoric and affective pain perception, their list of complaints, the common scale of depression and the pain disability index. Taking previously published studies into consideration, it is safe to say that a multidisciplinary, multimodal program of therapy even after stay in hospital results in considerable relief of pain and improvement in the ability to cope with the pain for patients with chronified pain syndromes in the muscular-skeletal system which are resistant to treatment on an outpatient basis.

    This paper presents a consumption-based Carbon City Index for CO2 emissions in a city. The index is derived from regional consumption and not from regional production. It includes imports and exports of emissions, factual emission developments, green investments as well as low carbon city...... development policies and stakeholder engagement. The index is based on a multi-region input-output model used in most parts of the world for more than half a century. We demonstrate the index through comparative case studies of three Danish regions: a rural region with a city center, the municipality...... of Sønderborg, a mid-sized city region, the municipality of Odense, and a metropolitan area, the municipality of Copenhagen. We demonstrate how city initiatives implemented to reduce emissions are translated into easy to access input-output parameters changes and how the index transparently assesses...

  11. Wallah. Indexing the new locality

    DEFF Research Database (Denmark)

    Skovse, Astrid Ravn

    This paper aims to add new, empirically based insights to the understanding of the dynamics by which linguistic features come to index locality. It does so through examining the indexicalities of the term wallah among adolescents living in the suburban, multi-ethnic Danish neighborhood Vollsmose....... The paper shows how the term wallah, by being emblematic of the enregistered voices of somewhat competing, locally constructed characterological figures (Agha 2005), comes to serve as an index of highly specific kinds of locality. The data comes from an experimental mapping method tapping into informants...... in a wide range of multi-ethnic settings in Scandinavia – wallah is nevertheless capable of indexing both local and supralocal sociolinguistic scales at once, reflecting the multiscalarity of the “new localities” of globalization (Blommaert 2010). By considering the possibility of features indexing a range...

  12. Trajectory Indexing Using Movement Constraints

    DEFF Research Database (Denmark)

    Pfoser, D.; Jensen, Christian Søndergaard

    2005-01-01

    With the proliferation of mobile computing, the ability to index efficiently the movements of mobile objects becomes important. Objects are typically seen as moving in two-dimensional (x,y) space, which means that their movements across time may be embedded in the three-dimensional (x,y,t) space...... is to reduce movements to occur in one spatial dimension. As a consequence, the movement occurs in two-dimensional (x,t) space. The advantages of considering such lower-dimensional trajectories are that the overall size of the data is reduced and that lower-dimensional data is to be indexed. Since off......-the-shelf database management systems typically do not offer higher-dimensional indexing, this reduction in dimensionality allows us to use existing DBMSes to store and index trajectories. Moreover, we argue that, given the right circumstances, indexing these dimensionality-reduced trajectories can be more efficient...

    Authors present an estimation of articulo-trochanteric-distance (ATD) and ATD index in patients with Perthes disease and if there is any correlation between ATD and ATD index and age at the onset, gender, type of treatment, Herring and Stulberg classification. The study population consisted of 242 patients (35 female and 207 male) who had reached skeletal maturity at last follow up. The mean age at the onset of symptoms was 7 years and 4 months. All patients were treated by containment methods (bed rest and traction in abduction, brace, Petri cast, varus osteotomy, Salter osteotomy and shelf operation). ATD was estimated according to the Edgren methods and ATD index was calculated as relation ATD on Perthes site to ATD in normal joint. The late results were classified according to the Stulberg classification. Statistical analysis did not revealed any correlation between the age at the onset, gender and ATD index and ATD during last follow up. Both parameters decreased with poor results according to the Stulberg classifications. ATD index and ATD were statistically significant less after surgical treatment than after non-operative treatment. The same relations were seen between patients with leg length discrepancy (LLD) and without LLD. Patients in Herring group A had statistically significant bigger both parameters than patients in group B, C and patients in Herring group B than C. Articulo-trochanteric-distance and ATD index decreased during follow up and ATD decreased also in normal joint. In our opinion ATD index is a more reliable radiological parameter than ATD. ATD index decreases with bigger necrosis of the femoral head and poor result according to the Stulberg classification. This parameter is an evidence of the dysfunction proximal femoral growth plate in patients with LLD. The most decreased ATD index was observed after surgical treatment. There was no correlation between the age at the onset, gender and ATD index at last follow up.

  16. Effect of Therapeutic Modalities on Patients With Patellofemoral Pain Syndrome

    Science.gov (United States)

    Lake, David A.; Wofford, Nancy H.

    2011-01-01

    Context: Patellofemoral pain syndrome (PFPS) is a common orthopaedic condition for which operative and nonoperative treatments have been used. Therapeutic modalities have been recommended for the treatment of patients with PFPS—including cold, ultrasound, phonophoresis, iontophoresis, neuromuscular electrical stimulation, electrical stimulation for pain control, electromyographic biofeedback, and laser. Objective: To determine the effectiveness of therapeutic modalities for the treatment of patients with PFPS. Data Sources: In May and August 2010, Medline was searched using the following databases: PubMed, CINAHL, Web of Science Citation Index, Science Direct, ProQuest Nursing & Allied Health, and Your Journals@OVID. Study Selection: Selected studies were randomized controlled trials that used a therapeutic modality to treat patients with PFPS. The review included articles with all outcome measures relevant for the PFPS patient: knee extension and flexion strength (isokinetic and isometric), patellofemoral pain assessment during activities of daily life, functional tests (eg, squats), Kujala patellofemoral score, and electromyographic recording from knee flexors and extensors and quadriceps femoris cross-sectional areas. Data Extraction: Authors conducted independent quality appraisals of studies using the PEDro Scale and a system designed for analysis of studies on interventions for patellofemoral pain. Results: Twelve studies met criteria: 1 on the effects of cold and ultrasound together, ice alone, iontophoresis, and phonophoresis; 3, neuromuscular electrical stimulation; 4, electromyographic biofeedback; 3, electrical stimulation for control of pain; and 1, laser. Discussion: Most studies were of low to moderate quality. Some reported that therapeutic modalities, when combined with other treatments, may be of some benefit for pain management or other symptoms. There was no consistent evidence of any beneficial effect when a therapeutic modality was used alone

    Science.gov (United States)

    Bentué-Ferrer, Danièle; Tribut, Olivier; Verdier, Marie-Clémence

    2012-01-01

    Rufinamide is a third-generation antiepileptic drug, available since early 2010 in France. It is indicated in combination therapy in the Lennox-Gastaut syndrome from the age of 4. It has orphan drug status. The bioavailability of rufinamide is high, but decreases with the dose and increases with food intake. Rufinamide is not metabolized by cytochromes but hydrolyzed by a carboxylesterase in an inactive carboxylic derivative. Elimination is mainly renal. The half-life varies from 6 to 10h. Although established from relatively few studies, exposure efficacy and exposure toxicity relationships are argued. A plasma concentration of 15 mg/L, obtained with a standard regimen, reduces the number of seizures of 25%. Few factors of intrinsic variability are described. There are few clinically significant pharmacokinetic interactions and they concern combinations with other antiepileptic drugs, especially valproate. Although there is no validated therapeutic range, the level of evidence for this therapeutic drug monitoring has been estimated at "possibly useful".

    1983-08-01

    The historic development of therapeutic communities is discussed, and it is shown that the term has been neither conceptualized not operationalized. Their unclear aims are considered to be utopian, and the author stresses that previous studies on such communities have been too superficial. The following problems have not hitherto received attention: 1. micro- and macrosocial relationships, 2. the role of the supervisor (authority problems), 3. norms and valuation systems, 4. discipline and sanctions, 5. the problem of roles, 6. questions of indicants and efficacy. The introduction of therapeutic communities is superfluous as a means of improving the socialist health services: it is sufficient to implement the principles of socialist democracy by means of appropriate training programmes.

    2012-01-01

    Stiripentol is a third generation antiepileptic, marketed since 2007 under the name of Diacomit(®). It is indicated, always in combination, in the treatment of severe myoclonic epilepsy in infancy or Dravet syndrome. Its pharmacokinetics is not linear. It is a potent inhibitor of CYP3A4, 1A2 and 2C19 and increases the plasma concentrations of many other antiepileptic drugs. Without this being considered as a validated therapeutic range, the trough plasma concentrations at steady-state, corresponding to the usual doses are between 10 and 15 mg/L. The concentration-efficacy relationship is not established, but there is some evidence for a concentration-related toxicity. However, because of its non-linear kinetics, stiripentol should be a good candidate for therapeutic drug monitoring (TDM). Nonetheless, the current level of evidence for the advantage of TDM is "remains to be estimated".

  20. Therapeutic approaches for celiac disease

    Plugis, Nicholas M.; Khosla, Chaitan

    2015-01-01

    Celiac disease is a common, lifelong autoimmune disorder for which dietary control is the only accepted form of therapy. A strict gluten-free diet is burdensome to patients and can be limited in efficacy, indicating there is an unmet need for novel therapeutic approaches to supplement or supplant dietary therapy. Many molecular events required for disease pathogenesis have been recently characterized and inspire most current and emerging drug-discovery efforts. Genome-wide association studies (GWAS) confirm the importance of human leukocyte antigen genes in our pathogenic model and identify a number of new risk loci in this complex disease. Here, we review the status of both emerging and potential therapeutic strategies in the context of disease pathophysiology. We conclude with a discussion of how genes identified during GWAS and follow-up studies that enhance susceptibility may offer insight into developing novel therapies. PMID:26060114

    1985-02-01

    Sciatica caused by root entrapment in the lateral recess was named superior facet syndrome by Epstein in 1972. Few reports on this subject based on large numbers of cases have been documented to date. Of the patients with sciatica, 32 patients were diagnosed to have root entrapment at the lateral recess L5 or/and S1 lumbar spine. Out of 32 patients, 20 patients were operated on and the lateral entrapment was recognized in all of surgical cases. Neuroradiological findings, especially of metrizamide CT (met. CT), were documented in detail. Thirty two patients were classified in three types according to radiological findings. They were congenital or developmental, degenerative, and combined type, respectively. Fourteen cases belonged to the congenital type, 13 to the degenerative and 5 to the combined type. Each group had the mean ages of 23.4, 53.8, and 36.8 years old, respectively. Of 32 cases the entrapment occured in 47 L5 roots and 11 S1 roots. There was no remarkable laterality. In operation the unroofing of the lateral recess were done and the sciatica subsided postoperatively in all of surgical cases. Met. CT revealed extreme medial protrusion of the superior articular joint in 18 of 24 cases(75%) and none filling of the root in the lateral recess in 21 of 24 cases (87.5%). In the degenerative type, met. CT showed some degenerative changes that were hypertrophy or deformity of the articular joints and spur formation of the vertebral body. In contrast to met. CT, metrizamide myelography revealed only slight changes, which were poor filling of the root before it turned out the pedicle of lateral compression of the root. In plain films or lumbar spine articular joints at Lsub(4/5) were formed in coronal plane in 69% of cases of the L5 root entrapment. Met. CT using ReView technique was of great diagnostic value in superior facet syndrome.

    Full Text Available Esse artigo, resultante de uma conferência, discute traços do processo de democratização do ensino superior. Procura distinguir analiticamente várias dimensões da democratização, baseadas, por sua vez, em concepções diferentes da justiça: igualdade de oportunidades, meritocracia, utilidades e equidade dos procedimentos. Cada sociedade constrói modelos de democratização desse ensino. A massificação do ensino superior desempenhou papel democrático objetivo, favorável aos grupos sociais antes excluídos. Mas massificação não equivale à democratização. Todas as categorias sociais não se beneficiam da mesma forma da massificação. A democratização do acesso ao ensino superior não depende apenas das famílias. Depende também da estrutura geral do sistema educativo. A meritocracia acadêmica constrói uma hierarquia de competências que é também social, com forte impacto reprodutivo. As desigualdades de utilidade das diferentes formações têm impacto sobre o conjunto das desigualdades sociais. Os sistemas educativos implementam distintos procedimentos de seleção, de concessão de gratuidades, bolsas e auxílios, que podem ser considerados como mais ou menos equitativos segundo as normas de justiça que mobilizam.

    2017-07-01

    Psilocybin and other 5-hydroxytryptamine2A agonist classic psychedelics have been used for centuries as sacraments within indigenous cultures. In the mid-twentieth century they were a focus within psychiatry as both probes of brain function and experimental therapeutics. By the late 1960s and early 1970s these scientific inquires fell out of favor because classic psychedelics were being used outside of medical research and in association with the emerging counter culture. However, in the twenty-first century, scientific interest in classic psychedelics has returned and grown as a result of several promising studies, validating earlier research. Here, we review therapeutic research on psilocybin, the classic psychedelic that has been the focus of most recent research. For mood and anxiety disorders, three controlled trials have suggested that psilocybin may decrease symptoms of depression and anxiety in the context of cancer-related psychiatric distress for at least 6 months following a single acute administration. A small, open-label study in patients with treatment-resistant depression showed reductions in depression and anxiety symptoms 3 months after two acute doses. For addiction, small, open-label pilot studies have shown promising success rates for both tobacco and alcohol addiction. Safety data from these various trials, which involve careful screening, preparation, monitoring, and follow-up, indicate the absence of severe drug-related adverse reactions. Modest drug-related adverse effects at the time of medication administration are readily managed. US federal funding has yet to support therapeutic psilocybin research, although such support will be important to thoroughly investigate efficacy, safety, and therapeutic mechanisms.

Transplantation of brown fat in small animal model systems has confirmed the expectation that brown fat expansion could possibly provide a novel therapeutic to combat obesity and related disorders. Expansion and/or stimulation of uncoupling protein-1 (UCP1)-positive adipose tissues have repeatedly demonstrated physiologically beneficial reductions in circulating glucose and lipids. The recent discovery that brown adipose tissue (BAT)-derived secreted factors positively alter whole body metabolism further expands potential benefits of brown or beige/brite adipose expansion. Unfortunately, there are no sources of transplantable BATs for human therapeutic purposes at this time. Recent developments in bioengineering, including novel hyaluronic acid-based hydrogels, have enabled non-immunogenic, functional tissue allografts that can be used to generate large quantities of UCP1-positive adipose tissue. These sophisticated tissue-engineering systems have provided the methodology to develop metabolically active brown or beige/brite adipose tissue implants with the potential to be used as a metabolic therapy. Unlike the pharmacological browning of white adipose depots, implantation of bioengineered UCP1-positive adipose tissues offers a spatially controlled therapeutic. Moving forward, new insights into the mechanisms by which extracellular cues govern stem-cell differentiation and progenitor cell recruitment may enable cell-free matrix implant approaches, which generate a niche sufficient to recruit white adipose tissue-derived stem cells and support their differentiation into functional beige/brite adipose tissues. This review summarizes clinically relevant discoveries in tissue-engineering and biology leading toward the recent development of biomaterial supported beige adipose tissue implants and

    Full Text Available Yessotoxin (YTX is a polyether compound produced by dinoflagellates and accumulated in filter feeding shellfish. No records about human intoxications induced by this compound have been published, however it is considered a toxin. Modifications in second messenger levels, protein levels, immune cells, cytoskeleton or activation of different cellular death types have been published as consequence of YTX exposure. This review summarizes the main intracellular pathways modulated by YTX and their pharmacological and therapeutic implications.

    Malignant brain cancer treatment is limited by a number of barriers, including the blood–brain barrier, transport within the brain interstitium, difficulties in delivering therapeutics specifically to tumor cells, the highly invasive quality of gliomas and drug resistance. As a result, the prognosis for patients with high-grade gliomas is poor and has improved little in recent years. Nanomedicine approaches have been developed in the laboratory, with some technologies being translated to the ...
