The comparison of these fragment sequences with those of other animalsthrough blastn of GeneBank,the results indicated that the homologies of nucleotidesequence of the GH gene of yak with Bos taurus are 98%,and with Bubalus bubalis,Capra hircus,Ovis aries are 97%,94%,93%,respectively.

其中牦牛GH基因全序列与普通牛同源性为98％，与水牛、山羊、绵羊同源性分别为97％、94％、93％。

We obtained complete coding sequence of myostatin gene from Bos taurus, Bos indicus, Bos grunniens, Bos frontalis and Bubalus bubalis (swamp buffalo and river buffalo) by PCR fragments sequencing method. The molecular evolution characters of CDS of myostatin gene were analyzed.

运用PCR分段扩增测序法，获得普通牛、瘤牛、牦牛、大额牛、水牛MSTN基因编码区全序列，进而分析编码区序列的分子进化特征。

Smashed yak bone paste was subjected to the fermentation by Lactobacillus bulgarian or the enzymolysis by trypsinase,dispase or caroid,respectively,followed by the determination of dissociative calcium(Ca2+) content,amino acid nitrogen content and pH.

用保加利亚乳酸杆菌发酵和用胰蛋白酶、中性蛋白酶、木瓜蛋白酶酶解超微粉碎牦牛骨泥，测定骨泥中的游离钙(Ca2+)、氨基酸态氮含量和pH值的变化。

The tenth day we hiked down to the Changping Valley, getting cliffed out in several locations and having to cross a gorge at 13,600 feet.

第10天我们下撤到了长平沟，越过一些山崖，穿过峡谷，一路沿着牦牛的足迹于当天下午2：30我们终于返回了大本营。

Casein from the same individual during the colostral period differed in mobility as showed by alkaline urea-PAGE analysis.

牦牛初乳酪蛋白碱性-尿素PAGE分析显示，同一个体β-酪蛋白的电泳迁移率在初乳期有差异。

In the normal uterus, Cytokeratins immunolabelling were detected in glandular cell, luminal epithelial cell, Vimentin immunolabelling were detected in stromal cell and endoblastic cell; CK7 immunolabelling were not detected in any tissue of the yak utenus.

研究结果显示：未妊娠时，泛角蛋白在子宫内膜腺上皮细胞、腔上皮细胞内表达，波形蛋白在子宫内膜基质细胞内表达，平滑肌肌动蛋白在子宫平滑肌和血管平滑肌内表达，牦牛子宫任何部位均不表达角蛋白7；妊娠30天左右时，泛角蛋白在子宫内膜腺上皮细胞、子宫内膜腔上皮细胞、滋养层细胞、内胚层细胞和尿囊细胞内表达，波形蛋白在子宫内膜基质细胞和内胚层细胞内表达，平滑肌肌动蛋白在子宫平滑肌和血管平滑肌内表达，角蛋白7在尿囊细胞内表达，偶尔在腔上皮细胞的细胞核边缘表达；消化法进行原代培养时，组织经胶原酶消化并通过100目和400目筛网组合可以有效地分离原代子宫内膜基质细胞和子宫内膜腺上皮细胞；分离得到的子宫内膜基质细胞活率达90%以上，并可在体外传代7次以上；分离得到的子宫内膜腺上皮细胞活率可达85%以上，并可在体外传代5次以上；RPMI1640培养基最适合子宫内膜基质细胞和子宫内膜腺上皮细胞的生长，维持子宫内膜基质细胞正常生长的FBS添加量为20%，维持子宫内膜腺上皮细胞正常生长的胎牛血清添加量为30%。

Histological structure of follicular system in yaks during the estrous cycle was similar to that of cattle and buffalo.

结果表明，牦牛发情周期中卵巢卵泡发育的组织结构与其他牛基本相似。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
