Moreover, contrary to what we observed in case of Leu deprivation, deficiency in Phe led to a smaller increase in bacteriocyte number during nymphal development (+12.0 for AP3 and +8.1 for Phe0...

Based on commercially available aminopropyltrialkoxysilanes, new monosodium salts of organoalkoxysilanes (sodiumoxoaminopropyldialkoxysilanes) with two types of chemically independent...

The data also showed that, for specific prodrugs of DPDPE such as Phe0-DPDPE and DPDPE-Arg-Gly, the prodrug shows a significant improvement in permeability, compared with the parent compound.

We did, however, observe a trend toward increased bacteriocyte size in aphids reared on the Phe0 diet compared to the AP3 control diet (Supplementary Figure S3).

In the present report, low viscosity hyperbranched epoxy resins are synthesized using a simple A2 + B4 polycondensation reaction between pentaerythritol and the in situ prepared diglycidyl ether of bisphenol-A, with variation of the reaction time and amount of B4 reactant.

Jul 1, 2022 · 属于常染色体隐性遗传，是一种较常见的氨基酸代谢缺陷病，由于患儿苯丙氨酸代谢途径中酶缺陷，其尿中排出大量的苯丙酮酸等代谢产物而得名。 本病的主要临床特征为智能低下、癫痫发作和色素减少，发病率具有种族和地域差异。 2.PKU的筛查. 以苯丙氨酸（Phe）作为筛查指标，检测方法可以用荧光分析法、定量酶法、细菌抑制法和串联质谱法等。 3. PKU的诊断. 在新生儿哺乳后3-4 d，用厚滤纸采集其足底等外周血液晾干后送检，当Phe含量超过正常2倍 …

串联质谱多种遗传代谢病筛查是指运用串联质谱技术通过一滴血、一次实验对新生儿足跟血中的氨基酸、肉碱、琥珀酰丙酮等几十个指标进行检测，通过代谢指标的变化筛查包括甲基丙二酸血症、希特林蛋白缺乏症、原发性肉碱缺乏症等在内的数十种氨基酸、有机酸、脂肪酸氧化障碍等遗传代谢性疾病。 传统新生儿筛查技术一次实验只能检测一个指标，仅能实现针对一种疾病的筛查；串联质谱技术一次实验，可以检测40多种检测指标，可实现多达40多种遗传代谢病的筛查。 实验 …
