This conclusion may contribute to the research for pathogenesis and diagnostic method of scrapie and bovine transmissible spongiform encephalopathy.

本研究确定了5株单抗在PrP分子上的结合部位，为羊痒病和牛海绵状脑病的检测、发病机制的研究奠定了基础。

Having two single sugars instead of one double sugar means that ounce-for-ounce honey contains more sugar molecules, which is why honey is also a little sweeter than table sugar.

含有两种单糖，而不是一种双糖，那就意味着每盎司的蜂蜜包含更多的糖分子，这就是为什么蜂蜜要比蔗糖甜一点的原因。

Thymus and autoimmunity: production of CD4+CD25+ naturally anergic and suppressive T cell as a key funtion of the thymus in maintaining immunologic selftolerance.

在人、大鼠和小鼠中有大约3%-10%的CD4+CD8-单阳性胸腺细胞共表达CD25表面分子，这些细胞能够阻止包括自身免疫性胃炎、自身免疫性小肠炎和自身免疫性糖尿病等在内的多种自身免疫性疾病的形成和发展［8-10］。

The result is that both tin atoms are five-coordination, have a distorted trigonal bipyramidal geometry with an additional week interaction between another oxygen atom and tin atom.

分子中四个羧酸酯基有桥联双齿和单齿两种不同的配位模式；在内环锡和外环锡的配位单元中，锡均形成具有五配位的畸变三角双锥配位构型，同时另有一氧原子与中心锡原子之间有弱相互作用。

Crystal structural analysis reveals that, because water molecules bond to Cu atoms, the dhbd ligand can only adopt a hydroxyl oxygen atom to bridge two reversed U-shaped subunits into a novel centrosymmetric dual-U-shaped tetranuclear Cu structure. Each U-shaped frame consists of two crystallographically distinct Cu atoms, two dpphen ligands and one coordinated water molecule.

晶体结构分析表明，由于水的配位阻断， 2，3-二羟基丁二酸根仅通过单羟基氧桥联两个U形双核亚单元形成具有一个对称中心的双U形四核结构，其中U型亚单元包含晶体学上不对称的2个Cu原子、1个2，3-二羟基丁二酸根、2个4，7-二苯基-1，10-邻菲咯啉和1个配位H2O分子。

The crystal is monoclinic,space group 〓, the ligand coordinates to Ni acetate in the enolic form,and produces a square complex.

单晶的结构是：晶体属于单斜晶系，空间群为〓，镍原子位于平面四方形配位中心，配体分子是以内式的烯醇式向镍原子配位的。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。
