端细胞

Objective To investigate the diagnostic significance oftelomerase activity in the exfoliated stomach cells sampling from endoscopic brushing.

目的：探讨胃镜直视下刷取胃粘膜脱落细胞中端粒酶活性对胃癌的诊断价值。

Mr. West's dream was to clone telomerase, the "immortalizing enzyme," for potential application in substantially extending cell life and maybe the lives of humans.

韦斯特先生的梦想是要克隆&永生酶&端粒酶，来尝试充分延长细胞的寿命，并因此延长人类的寿命。

Cell bodies in the nucleus intermedius and the most anterior of nucleus motorius dorsalis nervi vagi et nucleus nervi glossopharyngei were labeled.

分别在延髓的内侧核(Nucleus intermediu，简称IM)和舌咽—迷走神经背运动核(Nucleus motorius dorsalis vagi nervi et nucleus nervi glossopharyngei，简称nⅨ—Ⅹ)的最首端获得标记细胞。

Methods: The effect of ICA on the telomerase activity and proliferation and differentiation of HL-60 cells was compared with ATRA and valuated in vivo and in vitro.

采用ICA与全反式维甲酸对比试验，观察ICA对白血病细胞端粒酶活性及增殖分化的影响。

There was no acrosome lied anterior to the nucleus. There was a fossa in the end of the head and centrioles and mitochondria were located in the fossa.

头部后端凹陷，称为植入窝，植入窝内有线粒体和中心粒等细胞器结构，此区域为精子的中片。

In this study, the direct interaction between c-Abl and HSP70L1 was demonstrated by co-immunoprecipiation, in vitro binding assay and Far-Western blot.

本研究利用免疫沉淀、免疫印迹、GST-Pull down以及Far Western等方法证明了HSP70L1通过C端的120氨基酸片段与c-Abl在细胞内存在直接的相互作用。

Krana also physically interacts with ATM via its N-terminal KRAB domain. Thus, Krana bridges ATM to p53 and stabilize the interaction between p53 and ATM in vivo which is also abolished by heat shock or MMS treatment.

我们发现，Krana通过其N端的KRAB结构域与ATM结合，作为桥梁蛋白稳定ATM和p53在细胞内的结合；热休克和MMS处理后，三者的相互作用解离。

Chromosome number in all counted complete metaphases of Carassius auratus var. Dongtingking is 48. Analysis of chromosome can be divided into four sections according to the position of the centromere.

核型分析结果表明，翘嘴鲌的肾细胞染色体组是由48条染色体组成，染色体组型按着丝粒位置可分为四组，分别是中部着丝粒染色体、亚中部着丝粒染色体、端部着丝粒染色体。

The discovery of the telomere, that portion of human DNA that controls life span in cells, is one such development.

发现DNA的端粒来控制细胞寿命，就是这样的一个很大的进步。

A telomere is at each end of a chromosome. Telomeres are necessary for a cell to divide.

端粒位于每个染色体的末端，对细胞的分裂是必需的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
