Fetal and maternal plasma cortisol levels during labour and after delivery in the human.
In a group of 15 cases the cortisol concentrations were determined in fetal and maternal plasma during labour and after delivery. In maternal plasma the levels were about twice as high as in fetal plasma and rose up to more than 1000 mug/l during labour (x = 639 +/- 222). After delivery the concentrations decreased. In fetal plasma, cortisol increased during labour from x = 173 +/- to x = 276 +...
متن کاملFetal fraction of cell-free DNA in maternal plasma in the prediction of spontaneous preterm delivery.
OBJECTIVES To investigate whether, in pregnancies complicated by spontaneous preterm delivery, fetal fraction of cell-free DNA (cfDNA) in maternal plasma at 11-13 weeks' gestation is altered and if this measurement could be useful in the prediction of preterm delivery. METHODS Fetal fraction of cfDNA was measured at 10 + 0 to 13 + 6 weeks' gestation in 3169 pregnancies, 3066 (96.7%) that deli...
متن کاملMaternal intake of antioxidant vitamins in pregnancy in relation to maternal and fetal plasma levels at delivery.
The aim of the present study was to test the hypothesis that maternal intake of antioxidant vitamins is associated with maternal and cord plasma levels at delivery. Women were recruited in early pregnancy in Aberdeen Maternity Hospital and habitual diet during pregnancy was assessed by a food-frequency questionnaire mailed at 34 weeks gestation. Blood samples were taken at recruitment (n 1149) ...
متن کاملO-45: Quantification of Cell-Free-Fetal-DNAfrom Maternal Plasma for the First Time in Pakistan:Diagnosis of Genetic Disorders
Background: Current prenatal diagnosis requires invasive testing which carries a 1-4% procedure-related-risk of miscarriage; hence, non-invasive techniques are desired. The recent demonstration of cell-free-fetal-DNA enriched from maternal plasma has opened new possibilities for non-invasive-prenatal-diagnosis of not only genetic-disorders such as β-thalassaemia and haemophilia but also chromos...
متن کاملFetal fraction in maternal plasma cell-free DNA at 11-13 weeks' gestation: effect of maternal and fetal factors.
OBJECTIVE It was the aim of this study to examine the possible effects of maternal and fetal characteristics on the fetal fraction in maternal plasma cell-free DNA (cfDNA) at 11-13 weeks' gestation. METHODS In a nested case-control study, cfDNA was extracted from maternal plasma obtained before chorionic villous sampling from 300 euploid, 50 trisomy 21 and 50 trisomy 18 pregnancies at 11-13 w...
