Objective To determine the diversity of lysosome expression in neural stem cells during the neuron-oriented differentiation process.

随着神经干细胞(neural stem cells，NSCs)研究的不断深入，探索神经干细胞增殖、分化机制尤其是其定向分化机制倍受人们关注。

Lysosome is closely related to tubulin in neuron-oriented differentiation process of neural stem cells, and they both take part in the transportation of intracellular matter.

在神经干细胞向神经元定向分化过程中溶酶体与微管蛋白关系密切，共同参与细胞内物质的运输。

The contents of this paper arc as follows: teaching, training, injury and making map.

从定向运动教学、训练、运动损伤和地图制作等方面的现状进行了探讨。

The zonula adherens typically appears as a close and consistent apposition (15-20 NM) of the cell membranes close to the apical cell surface and surrounding the entire cell.

其表面为细胞膜，内为胞质，胞质中含纵行微管；纤毛较微绒毛粗且长，光镜下可见。功能：纤毛可定向摆动，把表面的分泌物及灰尘等向远处推移。

The versatile, open architecture approach that this new system is based upon will allow the customer to use existing equipment such as missile warners and countermeasures dispensers--while improving the survivability of these helicopters significantly with the addition of modern, laser DIRCM capability--and allow continued future growth.

新系统采用多功能开放式结构，允许客户使用诸如导弹告警器及对抗布撒器等现有设备，同时加入现代化激光定向能红外对抗能力显着改善直升机的生存能力，保持未来持续增长。

The pHybLex/Zeo-Idl plasmid and the cDNA library plasmid were sequentially transformed into the yeast swains and screened to obtain Leu2^＋ and Leu2^＋LacZ^＋ clones, with the false positive clones excluded using positive and negative controls, and the plasmid of the true positive clone was sequenced and blasted for homological analysis.

方法PCR方法扩增Id1的编码序列并定向克隆入诱饵质粒pHybLex/Zeo，构建重组诱饵质粒pHybLex/Zeo-Id1，酶切鉴定后转化入酵母株EGY48/pSH18-34，检测重组诱饵质粒有无非特异激活报告基因Leu2、LacZ作用；扩增并提取成人肺组织文库质粒，将文库质粒及重组诱饵质粒转化入酵母细胞，依次筛选Leu2^＋，Leu2^＋LacZ^＋克隆；设置阴性及阳性对照，重复筛选Leu2＋LacZ＋克隆并排除假阳性克隆，获取真阳性文库质粒，进行测序和同源性比对。

Maybe all that's needed is some refocusing.

或许所有需要的就是重新定向。

Hired to do? Maybe all that's needed is some refocusing.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
