Purpose: During cell-cycle progression, D-cyclins activate cyclin-dependent kinases (CDKs) 4/6 to inactivate Rb, permitting E2F1-mediated S-phase gene transcription. This critical pathway is typically deregulated in cancer, and novel inhibitory strategies would be effective in a variety of tumors. The protein synthesis inhibitor silvestrol has potent activity in B-cell leukemias via the mitocho...

هزینۀ ساخت سدهای بتنی وزنی به طور معمول بیشتر از هزینۀ ساخت سدهای دیگر است و بنابراین بهینه سازی شکل مقطع این گونه سدها به منظور کاهش در حجم بتن مصرفی باعث اقتصادی تر شدن طرح می شود. در این پژوهش، ضمن توسعۀ مدل بهینه سازی جفت گیری زنبور عسل در محیط نرم افزار متلب، ابعاد سد بتنی وزنی کوینا با در نظر گرفتن شرایط پایداری بهینه شده است. برای این کار، مقطعی کلی و فراگیر به عرض واحد شامل هشت ...

I read with interest the article by Lim and coworkers, detailing the effect of implementation of the European Working Time Directive (EWTD) on operative training at Papworth Hospital [1]. The findings of this study are impressive, but may not reflect the wider experience of UK trainees. The Royal College of Surgeons of Edinburgh has performed nationwide surveys of the attitudes of UK and Irish ...
BACKGROUND Previous studies regarding the impact of cigarette smoking on the risk of hip fracture in postmenopausal women have been inconsistent, suggesting different effects in different groups. The effect of alcohol intake on fracture risk is puzzling: moderate alcohol intake appears to increase bone density, and its association with hip fracture is not clear. METHODS To assess the associat...
Thyrotropin-releasing hormone (TRH) is a tripeptide that rapidly enhances prolactin secretion in clonal, hormone-responsive GH3 rat pituitary cells. In an effort to identify postreceptor mechanisms for TRH, protein phosphorylation studies have been conducted. Our previous studies (Drust, D.S., Sutton, C.A., and Martin, T. F. J. (1982) J. Biol. Chem. 257, 3306-3312; Drust, D.S., and Martin, T. F...

Research in rehabilitation has grown from a rare phenomenon to a mature science and clinical trials are now common. The purpose of this study is to estimate the extent to which questions posed and methods applied in clinical trials published in Clinical Rehabilitation have evolved over three decades with respect to accepted standards of scientific rigour. Studies were identified by journal, dat...
