The interaction between bovine serum albumin and such a natural pharmaceutical homologue as coumarin, umbelliferone and aesculetin was investigated using fluorescence spectroscopy and ultraviolet spectroscopy.

运用荧光光谱、紫外光谱法研究了三种香豆素中药小分子与牛血清白蛋白的相互作用。实验结果表明，香豆素类小分子能够插入BSA分子内部与BSA形成基态复合物导致BSA内源荧光猝灭，猝灭机理主要为静态猝灭和非辐射能量转移。

Two experiments were conducted to investigate the effects of diatary supplementation with sunflower oil plus calcium pyruvate on rumen fermentation and fatty acids of cis9, trans11-CLA and trans vaccenic acid (trans 11-C18, TVA) in ruminal digesta.

为研究添加葵花油和丙酮酸钙对山羊瘤胃消化代谢、瘤胃内容物中共轭亚油酸(c9， t11-CLA)含量及组织内源合成CLA前体反式油酸积累的影响，进行了体外与体内两组试验。

Effects of extragenous enzymes on the development of gut, digesta pH value, vili structure of small intestine, growth performance of piglets, effects of extragenous digestive enzymes and polysaccharide enzymes on endogenous enzymes activities were also determined.

试验研究了外源酶对仔猪消化道组织生长、食糜pH值、小肠绒毛形态结构及生长性能的影响及添加消化酶和聚糖酶对仔猪消化系统内源酶活（胃蛋白酶、胰蛋白酶、胰淀粉酶和粘膜二糖酶）的影响。

In vitro associstion experiments indicate that the plasmid pAy6.8 containing the core region of Antheraea yamamai fibroin gene can tightly bind to the nuclear matrix of Bombyx mori fertilized eggs,and recognize the same binding sites of homogeoous MAR fragments.

体外结合实验表明，携带天蚕丝素基因核心区的质粒pAy6.8可与家蚕受精卵核基质紧密结合，而且同内源MAR片段竞争结合位点。

Notably,knocking down of endogenous CUEDC2 by its specific shRNA nearly abrogates estrogen-independented degradation of ERα,suggesting that CUEDC2 is involved in ERαdegradation.

进一步我们发现CUEDC2能够以雌激素非依赖的方式下调ERα的蛋白质水平，干涉内源CUEDC2后，ERα的蛋白质水平明显上调，并且有效废除了雌激素对ERα的降解，Rescue实验证明了CUEDC2对ERα蛋白质水平的负向调控具有特异性。

In order to get the yeast feed of active-peptide and amino acids, Candida utilisl422 were autolyzed by the proteinase at the proper conditions.

利用内源酶系对产朊假丝酵母进行自溶，即得富含活性肽和多种游离氨基酸的饲用酵母提取物。

This polymer can be biodegraded to glutamic acid in nature or in human body and cannot be accumulated.

这种高分子在自然界或人体内可以生物降解成内源物质谷氨酸Glu，不易产生积蓄和毒副作用。

So,it is suggested that decreasing of iPA/ABA and GA/ABA andincreasing of IAA/ABA simulaniously are the characteristic changes of hormone at the beginingof bulbing.

因此，作者认为，iPA/ABA和GA/ABA下降，同时IAA/ABA上升，是大蒜鳞茎形成起始的内源激素平衡变化特征。

At the beginning of bulbing,contents of IAA and ratio ofIAA/ABA increased while ratios of iPA/ABA and GA/ABA decreased.

但在鳞茎形成开始时，内源IAA大幅度升高，同时GA含量下降，至鳞茎形成过程中，GA含量又上升。

Of damaged body cells, and a restoration and firming up of our well-being.

这表明增加我们健康内源能力对毒性和环境压力。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.
