活化

Much more prolongation ofsurvival term and improvement of survival rate,as well as appearance of a great dealof lymphocytes around pulmonary metastatic nodes and less pulmonary metastaseswere also observed in murines treated with activated、tumor antigen-pulsedmacrophages contrast to those treated with IL-2 gene-transfected macrophageswithout prior pulse of tumor antigen in vitro.

肿瘤抗原冲击的IL-2基因转染巨噬细胞治疗组小鼠期存活明显延长，肺转移结节明显减少，局部病理显示，肺肿瘤周围出现大量淋巴细胞浸润，我们推测这可能是因为抗原冲击的活化巨噬细胞除了增强对肿瘤细胞直接的杀伤效应外，还对其进行处理加工，将免疫信息传递给周围的淋巴细胞，从而引起其增殖活化，并浸润肿瘤组织中。

The analysis of decomposition mechanisms of the catalyst surface revealed that one of the mechanisms is that activated gas phase O2 captures the hydrogen of the organic pollutants to produce free radicals, which then initiate the catalytic reaction, and produce CO2 and H2O ultimately; and the other mechanism is that the activated organic compounds attack the crystal lattice oxygen, which reduces the valances of the transition metals, then the oxidant of the oxygen oxidizes the transition metals to high valances, which realize the self oxidation-reduction of the catalyst.

催化剂表面有机物降解的机理分析表明，一种反应机理为气相中的O2活化后直接夺取有机污染物的氢，产生自由基，并引发催化反应，最终生成CO2和H2O；另一种反应机理为活化后的有机物直接进攻催化剂的晶格氧，并且使得过渡金属由高价态变为低价态，反应气中的O2再将低价态的金属氧化为高价态，实现催化剂自身的氧化还原循环。

Objective To study the relationship between LAK/activated NK cells and hematopoiesis as well as the effects of LAK/activated NK cells on hematopoietic reconstitution after syngeneic bone marrow transplantation in mice.

The protein interaction domains was delineated at the N-terminal 50-amino-acid fragment of HCV core protein and the C-terminus of p53. Confocal analysis also revealed that these two proteins colocalize in subnuclear granules and peri-nuclear region. Transfection experiments using a p53-responsive reporter plasmid in HuH-7, Hep3B, HepG2 and H1299 demostrated that full-length HCV core protein could elicit a positive or negative effect on the p53-mediated transcriptional activation depending on the concentration of the HCV core protein.

更且利用p53蛋白C端删除55-95个胺基酸之质体与含p53蛋白结合区之报导基因和表现全长HCV核心蛋白三者之质体於H1299细胞株进行共同转染时，与全长p53蛋白比较，发现HCV核心从增强全长p53蛋白之转活化能力转为抑制p53蛋白缺乏C端55-95个胺基酸之转活化能力，因实验室已有结果证实活体外及活体内缺乏C端55个及75个胺基酸之p53蛋白无法与HCV核心蛋白进行结合(Kao， unpublished data)。

In mammals the Notch gene family comprise four related genes, Notch1-4, as the Notch ligands that encode transmembrane proteins. Ligand-receptor interaction mediated Notch activation ultimately leads to the conversion of effectors-CSL CBF1, Su(H, Lag-1 proteins, from repressors to transcriptional activators, and subsequent up-regulation of downstream targets.

在哺乳动物中，Notch基因家族包含了4个相关的基因，分别为Notch-1至-4，和Notch受质蛋白一样能被转译成膜蛋白；受质-受体间相互作用所引起Notch受体蛋白的活化会促使作用蛋白-CSL CBF1， Su(H， Lag-1 蛋白扮演抑制分子或者是转录活化分子上的角色改变，并且进一步地正向调节下游的标的基因。

Based on three hypotheses, the single reaction model was used for the calculation of active energies during pyrolyzing of HBs (except OH-π) in coal for the first time, and the values agreed well with those obtained with other methods.

在三条假设的基础上，采用单一反应模型的理论，研究了煤中除OH-π以外的其它氢键热分解的活化能，通过该方法计算的氢键的热解活化能与通过其它途径得到的值接近

Fitting curves are in good agreement with the experimental results,the calculated kinetic parameters are in good agreement with those reported in term of modeling of the pyrolysis of the three components assuming hemicellulose,cellulose and lignin pyrolyzing independently and para...

采用非线性最小平方算法，按三组分独立平行一级反应热解动力学模型，模拟计算的曲线与实验结果吻合较好，求解的动力学参数与文献报道值吻合较好，且随着升温速率的加快，纤维素和木质素热解的活化能有增加的趋势，而半纤维素活化能有下降的趋势。

Carbon nanotubes are coated with Ni by a series of processes of optimization (oxidations, sensitization and activation) used to add activated sites on the surface of CNTs before electroless plating.

通过对镀Ni前碳纳米管的氧化、敏化和活化处理，在碳纳米管表面增加活化点，成功地在破纳米管表面镀上一层金属Ni，并用TEM对镀Ni前后的碳纳米管进行了表征。

The results indicated that the activation exten of nitrogen depends on the number of feedback orbitals.

一般来说，氮氮键活化越强，体系能量越高，在相同的活化程度下，自旋多重度高的体系较稳定。

The activation of oncogenes occured in most tumors, and is believed to play an important role in tumorigenesis.

在大部分的肿瘤中都发现有癌基因的活化，癌基因的活化被认为是导致肿瘤发生的重要原因。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
