The preliminary results showed that the extracellular domain of YWK- II protein was able to interact with the 303-376 aminoacids segment of the rat Mullerian inhibiting substance in a yeast two-hybridsystem.

我们利用分子生物学的方法对YWK-Ⅱ蛋白质的463位至674氨基酸及389位至574位氨基酸的两段肽段分别进行了表达、纯化、结晶和初步解析了其中一段胞外区的结构，并且得到了YWK-Ⅱ和MIS的复合物的晶体。

Green tea contains a number of flavonols with the basic structure Specific flavonols found in tea include myricetin (hydroxyls at carbon 3', 4', and 5'), quercetin (hydroxyls at positions 3' and 4'), and kaempferol (hydroxyl at position 4'), and their glycosides.

Approximately 80% of the triacylglycerols in coconut oil are trisaturated, with lauric acid concentrated at the sn - 2 positions, octanoic acids at the sn - 3, and myristic and palmitic at the sn - 1 positions.

在椰子油中约80%三酰基甘油是三饱和的，月桂酸集中分布在sn-2位，辛酸位于sn-3位，肉豆蔻酸和棕榈酸位于sn-l位。

The selective quenching by Hg2+ of the fluorescence of compound 1 was rationalized in terms of the formation of a nonfluorescent Hg2+-1 complex with enhanced intramolecular charge transfer compared to compound 1 itself.

基于等摩尔连续变化法、红外光谱和核磁滴定实验结果提出了传感分子1与Hg2+的1∶1型结合模式，其中1-位S原子和2-位胺N原子为Hg2+配位原子；结合光谱变化讨论了Hg2+结合显著增强分子内电荷转移的荧光猝灭机理。

These results indicated that the genetic variation within exon 2 appeared to have largely arisen by gene recombination and balancing selection. Alignment of the deduced amino acid sequences of the β1 domain coded by exon 2 revealed 6 synonymous mutations and 27 nonsynonymous substitutions at the 33 disparate sites.

对B-LBⅡ等位基因第二外显子所编码的B-LBⅡ分子β1结构域氨基酸序列比对发现，31个B-LBⅡ新等位基因属于26个等位基因主型；在β1结构域氨基酸序列的33个变异位点上，存在6个同义替换和27个错义替换。

In coding region of CBF4, SNP frequency is 1 SNP per 96.4 bp, one nonsynonymous mutation was detected from 25 av、203 av and 244 av accessions, which is the 205th site amino acid variation: glynval caused by the 1034th site (corresponding to 19696 site nucleotide of GenBank No.AB015478 as 1) nucleotide variation : GnT.

在编码区，SNP的频率为每96.4 bp一个SNP，其中发现25 av、203 av和244 av 3个生态型CBF4基因区域1034位(以GenBank登录号AB015478序列第19696位的核苷酸为1)碱基变化：GnT，引起第205位氨基酸变化：glynval。

Results The natrural labor rate of nulliparous women was high of birth process diagram Type Ⅰ and Type Ⅱ and Cephalic presentation score above 12.The vaginal aid delivery rate of birth process diagram Type Ⅲ and TypeⅣ and cephalic presentation score from 10 to 11 was high. All of the Type V and score below 9 accepted cesarean Section.

结果 产程图为Ⅰ型、Ⅱ型和头位分娩评分在12分以上的自然分娩率高；产程图为Ⅲ、Ⅳ型和头位分娩评分在11分的产妇阴道助产分娩率明显增高；产程图为V型和头位分娩评分在9分以下者全部采用了剖宫产。

Hillary, to wrest back the Democratic nomination for president from Barack Obama and Madonna, to prove that with her 26th album, Hard Candy, she can outsing and outsell her sexy younger pop star sisters like Gwen Stefani and Fergie.

一位是民主党的总统参选人，一心要从奥巴马的手中夺回提名的第一位女性参选者；而另一位-麦当娜，则是要证明她的第26张唱片，Hard Candy，是比当今性感年轻的流行偶像，象Gwen Stefani 和 Fergie，做的更出色，卖的更好的最新唱片

Liquid overfill shall be prevented by providing positive design and operation steps, such as two reliable and repairable level instruments and an independent high-level alarm that independently stop the filling operation by closing the filling valves.

通过积极的设计及操作步骤防止液体溢流，如安装一个可靠并可维修的液位仪表和一个独立的高液位报警装置（该高液位报警装置通过独立关闭注入阀而停止继续注入操作）。

In the thesis, a series of novel single and multi-armed oxadiazole bridging ligands and pyridyl-4, 5-imidazole dicarboxylic acid ligands have been synthesized. The coordination chemistry of these novel ligands with transition metal ions was investigated. In addition, two 1, 3, 4-oxadiazole bridging ligands end-capped by chelating Schiff-base coordination sites have been designed and synthesized. The coordination chemistry based on one of the two ligands with metal ions was primarily investigated.

本文报道了一系列新颖的含1， 3， 4-Oxadiazole杂环的单臂及多臂有机配体，研究了它们与过渡金属离子的配位反应化学；合成了吡啶基-4，5-咪唑二羧酸有机配体，研究了它们在水热条件下与过渡金属离子的配位反应化学；另外，还合成了1， 3， 4-Oxadiazloe杂环桥联的双Schiff-base有机配体，初步探讨了其与过渡金属离子的配位反应化学。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
