Their thermotropic phase behavior was investigated by differential scanning calorimetry and POM. It was found that T(subscript S-N) w and T(subscript N-I), of PMMAZO was slightly increased with the increased of the mass ratio of liquid crystal block segments. PEO and PMMA block affected the liquid cystal behavior of PMMAZO. Meanwhile, PMMA and PMMAZO obviously influenced the crystals property of PEO segments3 which was decreased as the increase of molecular weight of PMMA and PMMAZO segments.

以差示扫描量热仪和偏光显徽镜研究了ABC三嵌段共聚物PEO-b-PMMA-b-PMMAZO的热力学相转变行为，发现随着PMMAZO链段的质量百分比的增加，三嵌段共聚物中PMMAZO链段的T和T逐渐提高；同时，PMMA和PMMAZO链段的长短影响PEO链段的结晶性，随着液晶段PMMAZO和PMMA链段分子量的增加，PEO链段的结晶性减弱。

Cytogenetically, in the elderly AML group the incidence of good prognosis abnormalities including t(15;17), t(8;21), inv(16) was lower in elderly than in young patients (P＜0.05),and there was higher rate of poor prognosis abnormalities such as -5/5q-,-7/7q-,+8(P＞0.05), and Ph chromosome in elderly patients.

在老年组AML中，预后好的核型t(15；17)、t(8；21)及inv(16)发生率明显低于非老年组(P＜0.05)；预后差的核型-5/5q-、-7/7q-、+8及ALL中Ph染色体有较高发生率。

In addition, mRNA for the cytolytic molecules, perforin and FasL, were detected in the expanded γδ T cells, and the cytotoxicity of γδ T cells against hepatoma SMMC7721 cells was remarkably dependent on the extracellular Ca〓.

MEP激活的γδ T细胞表达穿孔素和FasL等与杀伤作用有关的效应分子，并且γδ T细胞对肝癌细胞株SMMC772l的杀伤作用有显著的〓依赖性。

In T cells,TGF-beta1 can inhibit their proliferation,inhibit the differentiation of Th1 and Th2,inhibit the differentiation of CTL,induce the generation of regulatory T cellsTregin B cells,TGF-beta1 can inhibit their proliferation,induce IgA class switch,it also can induce the apoptosis of immature and resting B cells;in NK cells,TGF-beta1 can inhibit the secretion of IFN-γand the cytolytic function of NK cells.

对T细胞，TGF-beta1可以抑制其增殖，抑制Th1和Th2细胞的分化，抑制CTL的分化，诱导调节性T细胞的产生；对B细胞，TGF-beta1可以抑制B细胞的增殖，诱导IgA的类别转换，还可以诱导不成熟和静息B细胞的凋亡。

These T cells are sometimes referred to as cytotoxic T cells.

这些T细胞有时被称为细胞毒性T细胞。

The degressive degree of the phase stability of t-ZrO〓 is not obviously, the t-ZrO〓 content decrease from 91% for ZrO〓 to 85% for composites.

但由于这种作用的程度较小，t相下降的幅度较小，1350℃热压烧结后，t-ZrO〓的含量由单相ZrO〓（3Y）中的91％下降至85％。

高质量光学观测目镜：40x（用于85 T* FL机身）或 30 x（用于65 T* FL机身

It was found from structure-electrochemical studies of hemoglobin that (1) electroreduction induces the T→R transition with chirality transition and umbrella conversed effect;(2) electric field induces the secondary structural transition between two α helices, which is smilar to the denaturalization of the protein;(3) The electrochemical reaction mechanism of EC including T→R transition and parameters have also been obtained.

在血红蛋白的结构-电化学研究中发现：（1）电化学还原诱导血红蛋白的T→R构型转化，手性转化的伞翻转效应；（2）电场诱导血红蛋白的两种α螺旋二级结构间的转化，属于电场诱导血红蛋白的部分变性；（3）获得血红蛋白电化学还原的包括R→T转换的EC机理和参数

In the presence of 500nM TTX, 70%M/T cells presented spontaneous activity. 80%M/T cells with spontaneous activity appeared excitory postsynaptic currents , which could be reverted at 20mv, 14%M/T cells appeared inhibitory postsy-naptic currents , which the reverse potential was -90mv. Few presented both EPSCs and IPSCs.
