查询词典 activation energy

Forty-eight hours after transfection, cells were harvested to determine luciferase activity by illuminometer. In the presence of RU486 a 40-fold maximum activation of the luciferase reporter gene was observed in cultured cells, whereas in the absence of RU486, no significant activation was observed. There was a positive correlation between the luciferase activation and RU486 concentration in a definite range. The results showed that the RU486-inducible regulatory vector was successfully constructed, which can be used to regulate the expression level of genes of interest in appropriate time by the inducer RU486. This inducible expression vector provides a platform for the research of gene regulation and gene therapy.

加入诱导剂RU486后，可以诱导表达荧光素酶，并在一定范围内两者呈正比，最高可以实现荧光素酶的40余倍的表达，而没有RU486时，几乎没有报告基因的表达，表明RU486诱导调控载体构建成功，可实现对目的基因的表达时间和表达水平的精确调控，为进一步的基因调控研究和和基因治疗提供了良好的工具。

Results In all 12 normal children, the blood oxygen level-dependent signal was negative, and the maximum response appeared to be located in the anterior and superior part of the calcarine fissure, which may correspond to the anterior region of the primary visual cortex. However, in 24 cases of PVL, no activated pixels in PVC in 4; weak and tiny activation in 6; deviated activation in 8; and both tiny and deviated activation in 3 cases.

在行走过程中，随着负荷等级的增加，竖脊肌收缩力增大，其AEMG值也相应增大；左手提与右手提对腰部两观察肌肉的激活程度具有同等效果；上楼时腰部竖脊肌、多裂肌的激活强度显著大于平地和下楼时的激活强度，而平地与下楼之间不存在差异。

In the experiment section, there"re three experiments investigating implicit attitude and dual-attitude model. In the first experiment, the author studies the effects of attitude strengthen on attitude"s automatic activation effect. In the second experiment , the author studies the effect of delay condition on the attitude"s automatic activation effect. Delay condition make experiment approach to mere exposure of attitude object, and two experiment demonstrate attitude"s automatic activation effect is the result of noncognitive processing.

第一个实验，探讨了态度强度对态度自动激活效应范式的影响，结果发现态度强度不是影响态度自动激活效应的因素；在第二个实验中，探讨了时距对态度自动激活效应的影响，时距控制使得实验更接近于态度物的单纯呈现，结果发现时距没有对自动态度激活效应产生影响，从而论证自动态度激活效应可能是非认知系统作用的结果，具有普遍性。

This experiment aimed to systematically investigate and analyze the ethanol activated rates of mouse oocytes, affected factors of oocytes activation, types and development of parthenotes, and the organization and roles of the cytoskeleton during pronuclear formation and migration and early embryo cleavage by ethanol activation of oocytes, embryo culture in vitro and immunofluorescence cyto-chemistry. The results:(1) The ethanol activation of mouse oocytes showed that the activated and developmental rates of oocytes increased significantly with the increase of ethanol concentration and extension of exposure time, but over concentration and exposure time would result in increased fragment rates significantly. 7% ethanol treated oocytes for 7min was the optimum activated condition.

本实验主要利用卵母细胞的乙醇激活、胚胎体外培养和免疫荧光细胞化学方法对小鼠卵母细胞乙醇激活效率、影响因素、孤雌胚类型、发育、原核形成、迁移及早期胚胎卵裂过程中细胞骨架的组装、作用等进行了系统的研究和分析，结果显示：(1)小鼠卵母细胞的乙醇激活结果表明，随着乙醇浓度的升高和作用时间的延长，卵母细胞激活率和发育率都显著提高，但乙醇浓度过高和作用时间过长会导致卵母细胞碎裂率的显著增加，7%乙醇作用卵母细胞7min 为最佳激活条件。

Our results indicate that 1 NSC606985, at nanomolar level, can effectively induce apoptosis in AML cells NB4 and U937 and significantly inhibit the proliferation without cell death in breakpoint cluster region–Abelson murine leukemia kinase-carrying leukemic K562 cells; 2 At such low concentrations, this agent also significantly inhibits the clonogenic activity of hematopoietic progenitors from patients with AML; 3 For apoptosis induction, NSC606985 rapidly induces the proteolytic activation of protein kinase Cδ with loss of mitochondrial transmembrane potential and caspase-3 activation; 4 Co-treatment with rottlerin, a PKCδ-specific inhibitor, completely blocks NSC606985-induced mitochondrial m loss and caspase-3 activation, while the

Taken together, our data showed that both the CSF-box and the octamer are important for the LPS-induced G-CSF promoter activity, moreover, the activation of MEK/ERK signaling pathway is indispensible for LPS-induced G-CSF expression in RAW264.7 macrophage.. It seems that LPS-induced activation of MEK/ERK pathway does not directly regulates NF-κB transactivity, but is essential for LPS-induced Oct-2 binding to the octmaer within G-CSF promoter and transcription activation of the G-CSF expression.

透过这些结果，我们认为MEK/ERK pathway的确参与LPS活化G-CSF表现的过程，虽然MEK/ERK pathway都影响了CSF-box以及octamer对G-CSF启动子所贡献的活性，但似乎MEK/ERK pathway的下游并非直接影响NF-κB调控基因转录的活性，而主要是影响了Oct-2对G-CSF启动子的调控。
