Dear Editor-in-ChiefMalignant melanoma is a tumor arising from melanocyte; this tumor rarely occurs before puberty, with higher mortality rate in males and better survival rate in female patients affected by metastatic melanoma (1, 2). These facts propose that a relationship and association may exist between estrogens and melanoma. The effects of estrogens are mediated by...
BACKGROUND Leukotriene receptor antagonists (LTRAs) are drugs which have been widely used more than ten years. As the use of LTRAs increases, our knowledge with respect to their side effects increases as well. OBJECTIVES The objective of our study was to evaluat the observed side effects of LTRAs used in patients with astma. PATIENTS AND METHODS 1024 patients treated only with LTRAs owing t...
introduction: brain-derived neurotrophic factor (bdnf) and its receptor, trkb, in the hippocampus are targets for adverse effects of stress paradigms in addition, bdnf and its receptor play key role in the pathology of brain diseases like depression. in the present study, we evaluated the possible role of hippocampal bdnf in depression during pregnancy, methods: to achieve the purpose, repeated...
Objective(s): Salsola collina is widely distributed along the Bohai coast and consumed as an edible plant by native residents. We have found surprisingly that S. collina extracts promoted gastrointestinal motility in mice previously. In the present study, effects of S. collina on gastrointestinal motility in rats and its underlying mechanism were explored.<st...
در این تحقیق روش حساس و نوینی جهت تشخیص بیماری آمیبیاز پیشنهاد شده است . اصول آزمایش بر این فرضیه استوار است که receptor های مخصوص آنتی ژن آمیب روی لنفوسیت های حساس شده میتوانند با این آنتی ژن ترکیب شوند. قبل از انجام آزمایش آنتی ژن آمیب را با آنزیم بتاگالاکتوزیداز conjugate میکنیم (a-z) . این آنزیم و همچنین ترکیب a-z در مجاورت substrate مخصوص خود (fdbg) fluorescein-d-b-galactopyronoside ایجاد ...
Introduction: Major depressive disorder is often associated with suicidal tendencies, and this condition accentuates the need for rapid-acting antidepressants. We previously reported that alkaloids (ALK) from Trichilia monadelpha possess antidepressant action in acute animal models of depression and that this effect is mediated through the monoamine and L-arginine-NO-cGMP pathways. This study i...
Meta-analysis is a standard statistical method used to combine the conclusions of individual studies that are related and the results of single study alone can not answered to deal with issues. The data are summarized by one or more outcome measure estimates along with their standard errors. The multivariate model and the variations between studies are not considered in most articles. Here we d...
This paper sheds some light on the problems associated with random effects gravity approaches. Arguments for the superiority of a fixed effects model are given both along intuitive and econometric lines based on a Hausman test. 2000 Elsevier Science S.A. All rights reserved.
This paper uses data drawn from the English Football League to model separate hazard rates for club managers for the 2001/2, 2002/3 and 2003/4 seasons. On average over the three seasons, approximately one-third of managers involuntarily exited employment status with their club. We model the hazard using a standard logistic model exploiting information on the spell at risk rather than the indivi...
Abstract Agonist bias occurs when different ligands produce distinct signalling outputs acting at the same receptor. However, its physiological relevance is not always clear. Using primary human cells and gene editing techniques, we demonstrate endogenous agonist with consequences for calcitonin receptor-like receptor, CLR. By switching receptor-activity modifying protein (RAMP) associated CLR ...
