Cell-free DNA release by mouse placental explants
Although suggested that "fetal" cell-free DNA (cfDNA) is derived from trophoblast cells, the exact origin is unclear. The studies in this report sought to demonstrate that placental tissue releases cfDNA in parallel with cell death, that the size range of cfDNA is similar to that found in maternal plasma, and that the cfDNA fragments are able to stimulate a proinflammatory cytokine response. Pl...
متن کاملassociation between papp-a and placental thickness
background: measuring of maternal serum pregnancy-associated plasma protein-a (papp-a) in first trimester can be a way for early detection of adverse prenatal outcome due to faulty placenta.objective: the aim was to determination of association between placental thickness in second trimester with low level of papp-a in first trimester.materials and methods: in this cohort study, serum papp-a of...
متن کاملCell - free DNA: بیومارکر نوین تشخیص آزمایشگاهی
به انواع مختلف اسیدهای نوکلئیک آزاد در پلاسما شامل قطعات DNA ژنومی،DNA میتوکندریایی، DNA و mRNA های ویروسی و همچنین انواع miRNA اصطلاحا Cell–free nucleic acid گفته می شود. بخش مهمی از این اسیدهای نوکلئیک آزاد در پلاسما را Cell–free DNA (cfDNA) تشکیل می دهد. cfDNA به صورت قطعاتی با وزن مولکولی حدود KB 21-0.18 در سرم یا پلاسمای افراد سالم و افراد مبتلا به بسیاری از بیماری ها قابل تشخیص هستند. ...

متن کاملAssociation between calcifying nanoparticles and placental calcification
BACKGROUND The purpose of this study was to examine the possible contribution of calcifying nanoparticles to the pathogenesis of placental calcification. METHODS Calcified placental tissues and distal tissue samples were collected from 36 confirmed placental calcification cases. In addition, 20 normal placental tissue samples were obtained as a control group. All the tissue samples were cultu...
