The events of cell cycle take place in the order of timing and space, which ensures that cell division and chromo...

细胞周期各事件按正常时空顺序发生，才能确保遗传信息忠实传递及细胞正常分裂。

Coming from the common precursor cells (Th0), Th1 and Th2 can commutate under the influence of different cytokines and antigens.

他们来自共同的前体细胞Th0，在不同的细胞因子、抗原等因素的影响下，可发生Thl与Th2的转换。

The study of the histopathology showed that the haemolymph in the disease crab decreased sharply, and was replaced by large amount of parasites, which was observed in muscle, heart and hepatopancreas from the disease crab. The pathological characteristics mainly appeared as cells swelling, necrosis, nucleus condensation and collaspe.

组织病理学观察发现，病蟹血淋巴急剧下降，代之以大量的寄生原虫，该寄生虫在病蟹的肝胰腺、鳃、心脏、肌肉等部位大量侵袭，并引起这些组织发生以坏死为主的变质性病变，其病理特征主要表现为：细胞肿胀、变性、坏死，某些细胞的细胞核固缩、碎裂或崩解。

Although numerous studies demonstrated that BP could induce cell cycle alternations,the molecular basis of this is still obscure so far.

尽管大量的研究证实BP可诱导细胞周期发生改变，然而，迄今为止，有关BP致细胞周期改变的分子机制尚未完全阐明。

Bone morphogenetic protein ; cell differentiation ; cell dedifferentiation ; isotope incorporation

骨形态发生蛋白；细胞分化；细胞反分化；同位素掺入

We use hyperpolarize and depolarize current to change the membrane potential and discharge activity of the cells, paired with selected orientation drifting grating stimulation. The subsequent orientation tuning properties were examined.

据此我设计实验让细胞在去极化，超极化和正常状态下接受长时间的非最佳方位光栅刺激，考查细胞的方位和方向选择特性是否会发生可塑性变化。

Recent study showed that the devitalization of DPC4 gene was present in nearly 50% of pancreatic carcinoma, which interrupted the TGF-βsignal pathway, so inactivation of DPC4 gene maybe one of the most important cause of pancreatic carcinoma. The present study was carried out to clarify the effect of DPC4 gene on human pareatic carcinoma cell line JF305, which can help us understand the growth and proliferation mechanism of pancreatic carcinoma and provide us the practical guidance on gene therapy of pancreatic carcinoma.

最新研究资料表明近一半的胰腺癌存在DPC4(deleted in pancreatic carcinoma)失活，进而使TGF-β信号传导途径中断，失去其对肿瘤细胞的抑制作用，导致细胞过度生长和增殖，因此DPC4的改变可能是胰腺癌发生、发展的重要原因之一[2]。

In contrast to N and Si, no major difference in cell growth rate and metal uptake was found for diatom cells maintained at different P concentrations Fig.

与此相反，以氮，硅，没有发生重大差异，细胞生长率和金属的吸收被发现的硅藻细胞保持在不同P浓度（图2）。

Based on the data observed in four seasons during May 2004 to February 2005 and collected during the red tide occurrence period from 2001 to 2005 in the Nanji Islands sea area, the seasonal variations in species composition, dominant species and cell abundance of phytoplankton in the sea area, their relations to the environmental factors and the occurrence conditions of dinoflagellate red tide in spring are analyzed.

根据2004年5月－2005年2月4个季节的调查资料以及2001-2005年赤潮发生时收集的资料，分析了南麂列岛海域浮游植物的种类组成、优势种类、细胞丰度的季节变化及其与环境因子的关系、春季甲藻赤潮发生状况。

Objective: The cogenesis and progression of tumor is associated with the disbalance of cell apoptosis and proliferation.

目的：肿瘤的发生发展过程是细胞的过度增殖和细胞凋亡受抑制的过程。

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.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
