The effects of electromagnetic fields on alpha-fetoprotein expression in the amniotic fluid of mouse embryo
Amniotic fluid (AF) is essential for fetal development and maturation during pregnancy. The levels of proteins in AF have been determined in many studies to screen for potential biomarkers of pregnancy-associated abnormalities. Alpha-fetoprotein (AFP) is a major AF and plasma protein produced by the yolk sac and the liver during the fetal period. APF serum concentrations are commonly used for s...
متن کاملAmniotic fluid acetylcholinesterase activity and alpha-fetoprotein in chromosomal anomalies and neural tube defects.
Measurement of alpha-fetoprotein concentration and acetylcholinesterase activity in amniotic fluid can be used to identify chromosomal defects as well as neural tube defects. In seven cases of trisomy 21 and one case of partial trisomy 3, alpha-fetoprotein concentrations were below the reference range but values for acetylcholinesterase activity were normal for the appropriate gestational age. ...
متن کاملOutcome of pregnancies associated with raised serum and normal amniotic fluid alpha fetoprotein concentrations.
Outcome of pregnancies associated with raised serum and normal amniotic fluid a fetoprotein concentrations Open neural tube defects are associated with raised concentrations of a fetoprotein in amniotic fluid and maternal serum. Raised maternal serum a fetoprotein concentrations have also been associated with fetal distress, intrauterine death, threatened abortion, multiple pregnancy, exomphalo...
متن کاملPreterm birth: prediction by alkaline Phosphatase, ferritin and alpha-fetoprotein in amniotic fluid
Objective Preterm labor is a common health problem with has very serious adverse effects and burden of cost. Early diagnosis of preterm labor may be useful for prevention of its adverse effects. The aim of the present study was to evaluate levels of alkaline phosphatase (ALP), ferritin, and alpha-fetoprotein (AFP) in amniotic fluid in the second trimester of pregnant women for predicting preter...
متن کاملReactivity of amniotic fluid alpha-fetoprotein with concanavalin A in relation to gestational age: clinical implications.
We used concanavalin A crossed-line affinity immunoelectrophoresis to determine the percentage of concanavalin A nonreactive alpha-fetoprotein in amniotic fluid samples from pregnancies with normal and abnormal fetuses. In 167 samples from pregnancies with a normal outcome and normal values for total alpha-fetoprotein concentration in amniotic fluid the percentage decreased from a median value ...
