作者：阎培渝陈志城清华大学土木工程系教育部土木工程安全与耐久重点实验室北京100084 五邑大学土木建筑学院广东江门529020

高强混凝土的自收缩是导致其开裂的重要因素。为此,对不同水胶比的粉煤灰混凝土在水化初期的强度发展与自收缩的关系进行了研究。结果显示,粉煤灰混凝土的强度与自收缩均随着水胶比增加而下降,并随着粉煤灰掺量的增加而近似线性下降。... 详细信息

高强混凝土的自收缩是导致其开裂的重要因素。为此,对不同水胶比的粉煤灰混凝土在水化初期的强度发展与自收缩的关系进行了研究。结果显示,粉煤灰混凝土的强度与自收缩均随着水胶比增加而下降,并随着粉煤灰掺量的增加而近似线性下降。各种组成的混凝土的自收缩均表现为水化第1d内快速增加,随后缓慢增加。混凝土的收缩特性可根据其力学性能来预测。

Analysis of the mitochondrial proteome would provide valuable insight into the function of this important organelle, which plays key roles in energy metabolism, apoptosis, free radical production, thermogenesis, and calcium signaling. It could also increase our understanding about the mechanisms that promote mitochondrial disease. To identify proteins that are antigenically dominant in human liver mitochondria, we generated >240 hybridoma cell lines from native mitochondrial proteins after cell fusion, screening, and cloning. Antibodies that recognized mitochondrial proteins were identified by screening human liver cDNA expression libraries. In this study, we identified 6 major antigens that were recognized by at least 2 different monoclonal antibodies (mAbs). The proteins that were antigenically dominant were: acetyl-Coenzyme A acyltransferase 2 (mitochondrial 3-oxoacyl-Coenzyme A thiolase), aldehyde dehydrogenase 1 family member A1, carbamoyl phosphate synthetase 1, dihydrolipoamide S-acetyltransferase (E2 component of pyruvate dehydrogenase complex), enoyl coenzyme A hydratase 1, and hydroxysteroid (11-beta) dehydrogenase 1. We also determined the subcellular localizations of these enzymes within the mitochondria using immunohistocytochemistry. We believe that these well-characterized antibodies will provide a valuable resource for the Human Liver Proteome Project (HLPP), and will make studies aimed at investigating liver mitochondrial function far easier to perform in future. Our results provide strong evidence that, (i) depletion of dominant proteins from liver mitochondrial samples is possible and, (ii) the approaches adopted in this study can be used to explore or validate protein-protein interactions in this important organelle.

为了尽快推进彩色小麦的产业化进程,满足人们对营养型谷物的需求,实现食品营养天然、食用安全可靠。通过采用分层碾磨制粉技术和小麦抗粉碎硬度指数测定方法,研究彩色小麦的营养分布及硬度对各部分营养分离制粉的影响。结果表明,彩色小麦的氨基酸总体含量高于普通白小麦13.91%～23.32%,而其主要营养元素Se、Zn、Fe、Ca与普通白小麦比较,‘中普黑麦1号’和‘中普绿麦1号’的锌、铁、钙含量比普通白小麦偏高,而‘中普紫麦1号’则普遍偏低,特别是‘中普绿麦1号’铁和钙的含量比较突出,分别高于普通白小麦的371.80%和102.86%。同时,发现彩色小麦的结构营养分布等同于普通小麦,其果皮、种皮、糊粉层和胚芽具有丰富的营养。通过试验研究得出彩色小麦属营养型小麦,采用分层碾磨分离技术基本实现营养分离工业化加工的目的,同时发现影响营养分离加工的关键因素是小麦的硬度。该研究为彩色小麦营养资源的开发与合理利用提供了示范。
