查询词典 proliferation

EMF of 50 Hz frequency and 0.8 mT intensity can change intracellular free calcium ion concentration of bone marrow mesenchymal stem cells, and the change play a key role in the cellular proliferation and play a partial role in the differentiation of bone marrow mesenchymal stem cells into osteoblasts.

在50 Hz、0.8 mT电磁场作用下，骨髓间充质干细胞Ca2+内流发生变化，且该变化在骨髓间充质干细胞向成骨方向分化过程中产生部分抑制作用，在促其增殖过程中起主导作用。

Results: The proliferation of Kasumi-l cell was obviously inhibited by VPA on dose- and time-dependent manner. The IC50 was 2.33 mmol/L treated with VPA for 72 h. Incubation with VPA, the cell ratio at G0/C1 phase increased. VPA induced myeloid cell differentiation antigen CD11b to increase with a time-and dose-dependent way and caused apoptosis. Wright's staining and light microscope were used to show the morphology of partial differentiation and obvious apoptosis with 3 mmol/L VPA for 72 hours. The typical DNA ladder of apoptosis characteristic was observed with DNA gel electrophoresis.

结果：VPA能显著抑制Kasumi-1细胞的增殖，且呈剂量和时间依赖性，VPA处理Kasumi-1细胞72h时的半数抑制浓度(IC50)为2.33 mmol/L；VPA处理后，细胞周期检测G0/G1期细胞比例逐渐增高；VPA能诱导髓系分化抗原CD11b表达水平的阳性率升高，呈时间及剂量依赖性；VPA能诱导Kasumi-1细胞凋亡，Kasumi-l细胞经VPA3 mmol/L处理72h后，出现典型的凋亡细胞所具有的梯形DNA条带。

The research aimed to study the factors influencing the proliferation rate of butterfly orchids pedicel buds.

［目的］研究影响蝴蝶兰花梗芽增殖率的因素。

It was found that Pelargonium citrosum Vanleenii proliferation period can be prolonged in proper concentration of Ca~(2+).

结果表明：适当提高Ca2+的浓度，可以延长驱蚊香草试管苗的正常增殖生长周期；不同浓度的Ca2+处理对驱蚊香草试管苗增殖的影响要大于对其生根的影响；驱蚊香草试管苗体内Ca2+含量与试验培养基中Ca2+浓度成线性正相关。

ABSTRACT］ Objective To investigate the effect of calcitonin generelated peptide on the proliferation and apoptosis of HaCaT cells.

Specific siRNA was designed and synthesized, and transfected Hela with liposome siNEO FX, then analyse the role of siRNA on proliferation vitality outside the Hela cells, cells periodic distribution by MTT method, double-layer soft agar clone-forming assay, and flowing cell technology.

设计并合成siRNA，脂质体siNEO FX转染Hela细胞，分别用MTT法，双层软琼脂克隆形成试验和流式细胞术分析了siRNA对Hela细胞体外生长增殖活力、细胞周期分布的作用。siRNA作用后的Hela细胞增殖速度减慢，软琼脂克隆形成率降低，G0/G1，期细胞比率增加。

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
