Investigating the Complications of Transplacental Needle Passage in Amniocentesis
Background and purpose: Amniocentesis is the most commonly used method for diagnosis of aneuploid and other genetic disorders of the fetus. Cautious should be taken when entering the amniocentesis needle to avoid entering the placenta. The purpose of this study was to investigate the consequences of needle transposition from the placenta during amniocentesis. Materials and methods: In a cohort...
متن کاملTransplacental passage and fetal secretion of aldosterone.
The transplacental passage and the production of aldosterone were studied in late pregnancy during a constant infusion of 1,2-aldosterone-(3)H to mothers at the time of elective cesarean section. It was found that, while maternal aldosterone crossed the placenta, there was a significant secretion of aldosterone by the fetus. The aldosterone concentration in fetal plasma was 2-12 times higher th...
متن کاملTransplacental Passage of Interleukins 4 and 13?
The mechanisms by which prenatal events affect development of adult disease are incompletely characterized. Based on findings in a murine model of maternal transmission of asthma risk, we sought to test the role of the pro-asthmatic cytokines interleukin IL-4 and -13. To assess transplacental passage of functional cytokines, we assayed phosphorylation of STAT-6, a marker of IL-4 and -13 signali...

متن کاملTransplacental passage of insulin complexed to antibody.
The passage of plasma proteins across the placental barrier in humans is known to be highly selective. Thus, free maternal insulin has been reported not to cross the normal maternofetal barrier, although insulin-binding antibodies have been detected in newborn infants whose diabetic mothers received insulin therapy. In this report we demonstrate, with the use of a human antiserum that permits d...
