the purpose of this experimental study was to evaluate the effect of chicken amniotic fluid (af) on a cross section of rat sciatic nerves. thirty adult male sprague-dawley rats weighing 275 to 300 g, were randomized into three groups treated with (1) amniotic fluid or af (n=10), (2) normal saline or ns (n=10), and (3) sham surgery (n=10). the af was aspirated from the amniotic cavity of incubat...

We describe a fast atom bombardment mass spectrometric method to determine the ratio of lecithin to sphingomyelin in amniotic fluid. Between m/z 400 and 1000, amniotic fluid extracts showed clear peaks for only sphingomyelin and lecithin. The molecular species of fatty acid in the phospholipids were analyzed quantitatively and quickly in a small volume of the extracts. The dipalmitoyllecithin/p...

OBJECTIVE We explored the possibility that perturbations in amniotic fluid glucose, insulin, and insulin-like growth factor-binding protein 1(IGFBP1) and/or metabolic acids exist before routine screening for GDM. RESEARCH DESIGN AND METHODS We selected consenting mother-infant pairs (n = 408) who met our inclusion criteria (singleton pregnancy, no genetic abnormalities, and no preexisting dia...

Accurately predicting the volume of amniotic fluid is fundamental to assessing pregnancy risks, though task usually requires many hours laborious work by medical experts. In this paper, we present AmnioML, a machine learning solution that leverages deep and conformal prediction output fast accurate estimates segmentation masks from fetal MRIs with Dice coefficient over 0.9. Also, make available...

although amniotic fluid embolism is a rare event, but it is a tragic event. this kind of embolism occurs in 1 per 20,000 to 30,000 births with 86% maternal mortality rate in the united states. amniotic fluid embolism is in charge of near 10-15% of all maternal deaths. this article reflects the experiences of a nurse midwife encountered with a maternal and neonatal death due to an amniotic fluid...

We developed a mathematical model of monochorionic twin pregnancies and twin-twin transfusion syndrome (TTTS), combining both fetal fluid dynamics and fetoplacental growth and circulation alterations and assuming that transplacental fluid flow from mother to fetus accounts for normal fetal and amniotic fluid volumes. Ten coupled differential equations, describing fetal total body and amniotic f...

OBJECTIVE To test the hypothesis that cervical shortening in polyhydramnios reflects the degree of excess amniotic fluid, and increases with normalisation of amniotic fluid volume. STUDY DESIGN Prospective cohort study of 40 women with monochorionic twins undergoing interventional procedures between 16-26 weeks. Cervical length was assessed via transvaginal sonography pre-procedure, 1 and 24 ...

OBJECTIVE To test the hypothesis that unconjugated bilirubin is equally distributed over the albumin molecules present in fetal blood and amniotic fluid in Rhesus (Rh) immunization. METHODS Molar concentrations of unconjugated bilirubin and albumin were measured in fetal blood and amniotic fluid samples, obtained before the first intrauterine transfusion in 30 nonhydropic, anti-D-alloimmunize...
