细胞发生

The researching result of this field is conflicting in these years. Some researchers consider it as apoptosis, while some necropsy results don\'t support the hypothesis. Our study is to investigate the protein expression and biochemistry changes under oxidative stress to determine if apoptosis happens.

多巴胺能神经元的死亡是凋亡还是坏死目前的研究结果不一，有许多的研究说明在氧化应激的条件下，细胞的死亡是凋亡，而部分尸检结果不支持凋亡的学说，本实验拟从蛋白表达及生化学方面观察氧化应激后细胞有无凋亡的发生。

Six2-expressing cells give rise to all cell types of the main body of the nephron during all stages of nephrogenesis.

"The SDF1 and Ang1 proteins are what link the two processes of neurogenesis and angiogenesis together by promoting post-stroke neuroblast migration," said Carmichael.

"SDF1和Ang1蛋白是将神经发生和血管发生2个过程关联到一起的蛋白，通过触发中风后神经母细胞迁移来完成，"Carmichael说。

At the same time, the morphological changes in blood vessels, neuroglia cells and neurons were observed in rats.

结果显示在电磁脉冲辐照后，海马神经细胞不仅发生快速的坏死，而且还发生凋亡，同时在早期即可见到血管、胶质细胞和神经元等组织的形态学异常。

During segmentation,GFP was detected in the notochord but not in the foor plate.

GFP在原肠作用期就开始表达，主要发生在中轴下胚层中；在体节形成期，GFP在脊索细胞中表达，但未发现在神经底板细胞中表达。

Abstract］ AIM:To investigate the role of nuclear factor κB in the induction of iNOS gene by TNFα and LPS in endothelial cells and the effect of antioxidant on the induction of iNOS. METHODS:Nitrite was determined based on Griess reaction. iNOS mRNA was analyzed using Northern blot. NFκB in the cell nucleole was detected with electrophoretic mobility shift assay.RESULTS:(1)NO production and iNOS mRNA expression induced by LPS and TNFα was blocked by pyrrolidine dithiocarbamate or N-acetylcysteine.

研究表明内皮细胞激活时iNOS表达的调控主要发生在转录水平。iNOS基因的启动子区域含有多个转录因子的结合位点包括NFκB、AP-1、NF-IL6，Oct-1等［2］，而核因子κB(nuclear factor κB， NFκB)被认为在多种参与炎症反应的蛋白质因子的基因调控中担任重要角色，因而可能是内皮细胞激活的调控中一个重要转录激活因子［2，3］。

The transcription localizations of these polymerases have been studied since early 1960s. The results of these early research works showed that the transcription of RNA polymerase I was localized in the nucleoli while that of RNA polymerase Ⅲ in the nucleoplasm.

自上个世纪六十年代初期，人们相继运用细胞化学染色、电镜放射自显影等进行研究的结果表明：RNA聚合酶Ⅰ的转录发生在核仁中，RNA聚合酶Ⅲ的转录发生在核质中。

Analysis of risk factors for the interval time, number and pattern of hepatic metastases from gastric cancer after radical gastrectomy .

4.3 肝转移的发生机制研究目前认为胃癌肝转移的发生是由胃癌细胞经血道转移导致。

The occurence and development of asthma involved a complicated cells and cytokines net.

哮喘的发生发展涉及一个复杂的细胞和细胞因子网络。

The multiple unfolding that takes place is entirely dependent upon temporo-spatial overlapping, a continuous meeting in time and space, a sequence of events that must be precisely synchronized so that one phenomenon may act on another at the right time at the right place. The entire ontogenetic process must be seen as a precision schedule that determines the evolvement of a temporo-spatial pattern of interactions between cells and tissues.

多个未呈现的事件被呈现是完全依赖时间性空间的部分重叠，连续不断的会集在时间和空间上，一连串的事件可能同时被发生以便一个现象能在另一个正确的时间和地点活动，相互影响的一个时间性空间形式的发展在细胞和组织之间的整个个体发生过程必须被看作为一个精确的项目表。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
