Origin of raised maternal serum alpha-fetoprotein levels in second-trimester oligohydramnios

Concanavalin A (Con A) subtyping of alpha-fetoprotein (AFP) revealed higher concentrations of AFP non-reactive with Con A in sera of 12 pregnant women with second-trimester oligohydramnios and raised total serum AFP levels than in sera of 42 pregnant women with raised total serum AFP levels and a normal amniotic fluid volume. This suggests that in oligohydramnios the origin of excess AFP in the maternal compartment is amniotic fluid. It is proposed that oligohydramnios and the associated raised maternal serum AFP levels are caused by damage of the fetal membranes prior to 16 weeks of gestation resulting in leakage of amniotic fluid to the decidual tissue and resorption in the maternal circulation.     

Use of the chemical cleavage of mismatch method for prenatal deficiency diagnosis of alpha-1-antitrypsin

The most common mutation in alpha-1-antitrypsin deficiency, conversion of a G to an A at base 9989 (PI-Z), was detected with the chemical cleavage of mismatch method, demonstrating the power of the method for prenatal diagnosis. Exon V of the gene was amplified using the polymerase chain reaction and heteroduplexes were formed to test for the presence of the mutation. The predicted C mismatch was readily detectable with hydroxylamine, and by making the probe from the chorionic villus sample it was possible to determine that the fetus was heterozygous, not homozygous, for the mutation.     

熔池高度对双辊薄带凝固组织影响的模拟预测

在已建立的理论数学模型的基础上,以1Cr18Ni9Ti不锈钢为研究对象,模拟预测了薄带厚度保持不变条件下熔池高度对薄带凝固组织的影响。研究结果表明:随着熔池高度增加,1Cr18Ni9Ti不锈钢双辊薄带凝固组织中柱状晶区比例首先增大,然后又逐渐减小。而柱状枝晶取向度和枝晶间距则随着熔池高度的增加而增大,但在较低的熔池高度条件下,柱状枝晶间距在凝固结束时有突然增大的趋势。
