The persistent presence in plasma of medium to high levels of IgG and/or IgM class anticardiolipin antibodies (aCL) and/or the lupus anticoagulant (LAC) is associated with both “recurrent pregnancy loss” and venous and arterial thrombosis. This clinicoserological entity, first described in the early eighties in patients with systemic lupus erythematosus was termed the antiphospholipid syndrome ...
OBJECTIVE To explore the effects of interventions given to improve pregnancy outcome in women with antiphospholipid antibodies. DATA SOURCES Cochrane Controlled Trials Register, Cochrane Collaboration Pregnancy and Childbirth Group's Specialized Register of Controlled Trials, EMBASE, and MEDLINE were searched in December 1999. STUDY SELECTION Randomized or quasi-randomized controlled trials...

The knowledge that an early pregnancy loss is secondary to a sporadic genetic abnormality may provide parents with reassurance that there was nothing that they did or did not do that contributed to the loss, although the magnitude of this benefit i...
Vascular endothelial growth factor (VEGF) regulates endothelial cell proliferation, migration and differentiation. VEGF plays a critical role in angiogenesis during placenta formation. We investigated whether VEGF gene polymorphisms are associated with recurrent pregnancy loss. Thirty-eight women with recurrent pregnancy loss and 30 control women with live-born children were recruited from 2010...
در این پروژه فیلترهای مایکرواستریپ جدیدی برای بهدست آوردن اندازهی فشرده، پاسخ تیز و نیز باند قطع عریض ارائه شده است که از جملهی آن ها فیلتری است که از سری شدن یک رزوناتور شاخهای منتهی به نیمدایره و یک تکهی شعاعی بهبود یافته به عنوان تضعیف کنندهی هارمونیک، تشکیل شده است. فرکانس قطع -3 db این فیلتر در 1.54 ghz قرار دارد. باند گذر این فیلتر تنها 0.26 ghz است که شامل محدودهی فرکانسی 1.5...
