BACKGROUND Release of vascular endothelial growth factor (VEGF) by ovaries in response to HCG administration is one of the main mechanisms of ovarian hyper stimulation syndrome. Since Dopamine/dopamine receptor2 (Dp-r2) pathway activity -mediated by VEGF/ Vascular endothelial growth factor receptor 2 (VEGFR- 2) signaling-, is associated with angiogenic events, dopamine agonists were used for th...
زمینه و هدف: از حدود نیم قرن پیش گنادوتروپین های اگزوژن با روش های متنوعی، جهت القاء تخمک گذاری در درمان اختلالات تخمک گذاری و انجام روش های فن آوری کمک باروری استفاده می شوند. بدلیل کاربرد وسیع دو روش کاهش مرحله ای و روش با دوز ثابتhmg در القاء تخمک گذاری، هزینه بالا و عوارض زیاد ناشی از درمان و نیز عدم دستیابی به نتایج مشترک در خصوص ارجحیت یکی از این دو روش در مطالعاتی که قبلاً انجام شده است ا...
We propose in the paper a process, based on the use of a high velocity, electric arc metal spray thoroughly atomized on a master model in order to make a shell. The mold is realized by placing the sprayed alloy into a frame and reinforcing it with appropriate material. The first part of the paper presents briefly the main rapid prototyping and tooling techniques used in industry. We then descri...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
background : despite recent technologic improvements in identifying mycobacterium tuberculosis, we are still facing problems in rapid diagnosis of tuberculosis. the objective of this study is to determine the diagnostic value of a new rapid screening test (patho-tb™) for diagnosis of pulmonary tuberculosis. methods : between september 2006 to august 2007, 178 patients were enrolled in the study...
