Effect of Al₂O₃-Ce₂O₃ Composite Film on High Temperature Oxidation Resistance of 304 Stainless Steel [PDF]

Cailiao Baohu
In order to improve the high temperature oxidation resistance of 304 stainless steel， Al2O3 thin films and Al2O3-Ce2O3 composite films were respectively prepared on the surface of 304 stainless steel by sol-gel method using aluminum ...

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Application of colloidal dispersion gels in-depth conformance improvement in polymer flooding development of Daqing oilfield(胶态分散凝胶深度调剖技术在大庆油田聚驱开发中的应用)

Zhejiang Daxue xuebao. Lixue ban, 2002
介绍了大庆油田应用胶态分散凝胶深度调剖技术的凝胶成胶机理、影响成胶的因素、凝胶在多孔介质中的渗流特征及现场试验效果.室内岩芯模拟研究及现场典型井试验表明,流动凝胶在多孔介质中可流动,在单井注入15000～20000 m3流动凝胶体系过程中,注入压力逐渐升高,可以实现深度调剖,更好地提高聚合物驱采收率.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

VEGETABLE OILS AS EXTRACTANTS, METHODS OF OIL EXTRACTION INTENSIFICATION, PHARMACOLOGICAL PROPERTIES OF OIL EXTRACTS

Vestnik Farmacii
This article presents and analyzes the main physicochemical characteristics of oils as extractants for biologically active substances from medicinal plant raw material and their fatty acid composition. The process of traditional oil extraction using maceration, percolation, repercolation, and enfleurage is a relatively slow process.

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.
