We have shown that hypoxia reduces plasma insulin,which correlates with corticotropin-releasing hormone(CRH)receptor 1(CRHR1)in rats,but the mechanism remai
在强烈地震作用下的钢筋混凝土结构构件中，钢筋可能承受较大的反复拉伸和压缩应变，若对钢筋的约束不够，在受损混凝土的挤压下会导致钢筋出现大的侧向变形，即钢筋的屈曲。钢筋屈曲

生本教育“以学为本”,强调“先学后教,以学定教”.前置性学习作为一个教学环节,是“先学”这一原则最鲜明的体现.如何设计科学、合理的前置性作业让学生有效“先学”并乐于
本文首先对干酪乳杆菌进行紫外诱变和NTG诱变，得到蔗糖耐受性高的突变菌株，以此作为基因组改组的出发菌住，制得原生质体，将原生质体分别于紫外线和热灭活后融合，并在再生平板中培
