For many decades it has been thought that lifelong premature ejaculation (PE) is only characterized by persistent early ejaculations. Despite enormous progress of in vivo animal research, and neurobiological, genetic and pharmacological research in men with lifelong PE, our current understanding of the mechanisms behind early ejaculations is far from complete. The new classification of PE into ...

Syncope is the state of lack of consciousness and temporal loss of postural tone. Syncope might be in association with a variety of benign and life-threatening conditions. Pulmonary embolism (PE) has been shown to be associated with syncope in 13-30 percent of cases. This article presents a novel case report of PE whom syncope was his only manifestation.

premature ejaculation (pe) is one of prevalent male sexual dysfunctions worldwide. despite many psychiatric backgrounds, yet there are speculations about organic etiologies considering both anatomic and physiologic points of view. this survey assesses effect of frenular web preservation on premature ejaculation. one thousand and forty otherwise healthy men being visited for urolithiasis (asympt...

background: premature ejaculation is one of the most problems in clinical practice. the association between varicocele and premature ejaculation was poorly understood. the effects of varicocelectomy on premature ejaculation in varicocele patient was studied. objectives: the aim of this study was to determine the impacts of varicocelectomy on patients with both premature ejaculation and varicoce...

غلاف سوخت‌های هسته‌ای یکی از مهم‌ترین اجزا رآکتور محسوب می‌شود. این غلاف‌ها آلیاژ زیرکونیم ساخته می‌شوند؛ اما خواص ترمومکانیکی چندان مناسبی ندارند؛ لذا در پژوهش سعی شده با تغییر مواد به‌کاررفته NuScale به یک نوترونیکی و مناسب دست پیدا شود. قلب موجب ضریب تکثیر مؤثر طول بازه سوخت‌گذاری می‌گردد. شبیه‌سازی که M5 بهره می‌برد به‌عنوان معیار هم‌­چنین همراه سه نوع دیگر آلیاژهای رایج دو آن FeCrAl است، د...

The Drosophila wing imaginal disc is a sac-like structure that is composed of two opposing cell layers: peripodial epithelium (PE, also known as squamous epithelia) and disc proper (DP, also known as pseudostratified columnar epithelia). The molecular mechanism of cell morphogenesis has been well studied in the DP but not in the PE. Although proper Dpp signalling activity is required for proper...

Background: Cytomegalovirus (CMV) infection is one of the most common infectious diseases in pregnant women in terms of global impact and is related with many adverse health consequences during pregnancy. For the first time, we performed a systematic review and meta-analysis study to evaluate the possible association between CMV infection and preeclampsia (PE). Methods: A comprehensive literat...

Staphylococcal pyrogenic exotoxin (PE) ty pe C enhanced the susceptibility of rabbits to lethal shock by endotoxin by as much as 50,000-fold. A graph of log PE type C dose used for pretreatment versus log 50% lethal dose of endotoxin gave a straight line with a slope of approximately -1. Rabbits that received PE type C alone showed fevers only, but those given both PE ty pe C and endotoxin show...
