Activity of biotin-dependent and gaba metabolizing enzymes in chorionic villus samples: Potential for 1st trimester prenatal diagnosis

We have documented the presence of five mitochondrial enzymes in samples of chorionic villus tissue and measured the levels of activity. Three of the enzymes catalyse biotindependent reactions. These are propionyl-CoA carboxylase, 3-methylcrotonyl-CoA carboxylase and pyruvate carboxylase. the other enzymes. 4-aminobutyric acid aminotransferase and succinic semialdehyde dehydrogenase, are involved inthe degradation of the central inhibitory neurotransmitter GABA. Distinct diseases in whichthere is deficiency of each of these enzymes have been documented in man. Significant levels of activity were observed for all five enzymes in chorionic villus tissue. This methodology should permit early prenatal diagnosis of deficiencies of these enzymes by chorionic villus biopsy in the first trimester.     

The cerebro-hepato-renal (Zellweger) syndrome: Prenatal detection based on impaired biosynthesis of plasmalogens

Prenatal diagnosis of the cerebro-hepato-renal (Zellweger) syndrome has been performed in 10 pregnancies at risk by measuring both the activity of acyl CoA: dihydroxyacetonephosphate acyltransferase (DHAP-AT) and the de novo plasmalogen biosynthesis, either in cultured amniotic fluid cells or in fibroblasts cultured from a chorionic villus biopsy. In 7 of the pregnancies both tests indicated no abnormality. All 7 continued to term and normal infants were delivered. However, in amniotic fluid cells from 2 fetuses affected by Zellweger syndrome unequivocal differences from control values were found. The activity of DHAP-AT was clearly deficient and the de novo plasmalogen biosynthesis was impaired. In one pregnancy at risk prenatal diagnosis was performed during the first trimester by measuring both the DHAP-AT activity and the de novo plasmalogen biosynthesis in fibroblasts cultured from a chorionic villi biopsy. From the deficient DHAP-AT activity and the impaired de novo plasmalogen biosynthesis it was concluded that the fetus was affected. This was confirmed biochemically after induced abortion. It can be concluded that measurement of the DHAP-AT activity and the de novo plasmalogen biosynthesis provides convenient methods for the early prenatal detection of Zellweger syndrome.

基于高分辨率MARGA分析桂林市PM2.5水溶性离子特征

利用高时间分辨率MARGA于2017年2月17日~3月24日在桂林市开展PM_2.5组分监测，结合同一点位环境和气象监测数据，分析桂林市大气PM_2.5水溶性无机离子组分特征及气溶胶酸性.结果表明：MARGA监测的PM_2.5中8种水溶性离子与PM_2.5变化趋势一致.8种水溶性离子总浓度均值29.27μg/m³，3种二次水溶性离子SO₄^2-、NO₃^-和NH₄⁺浓度均值26.91μg/m³，占水溶性离子总浓度的93.50%，是桂林市大气PM_2.5的主要组分.二次水溶性离子SO₄^2-、NH₄⁺和NO₃^-两两之间存在显著正相关性（相关系数均>0.80），提示二次离子产生的机制及在大气中的演化、沉积具有一定的相似性.无论有无降雨，能见度（Vis）均随着水溶性离子，尤其是二次水溶性离子浓度的增加呈幂函数规律递减.24h累计降雨量≥ 10.0mm时，湿清除作用明显.晴天及降雨量不大的天气下，需注意管控机动车尾气、生物质燃烧和扬尘污染.SOR、NOR分别为0.35、0.12，SO₂同时通过均相和非均相氧化反应转化为SO₄^2-，NO_x主要是通过白天光化学反应转化为NO₃^-.大多数离子和气态前体物均存在明显的日变化规律，这与物质的来源、形成机制和气象条件不同有关.CE/AE摩尔浓度均值为1.5，桂林市PM_2.5总体偏碱性.PM_2.5中SO₄^2-、NO₃^-、Cl^-主要以（NH₄）₂SO₄、NH₄NO₃和NH₄Cl形式存在.PM_2.5中NH₄⁺可能与监测点位交通源排放有关，桂林市应加强交通污染物排放管控.
