Calcium activated potassium ionic channel is abbreviated to be BK, which is situated at the bottom of hair cell cilium, and is the important ionic channel of the electronic activity of hair cell, take part in the high frequency hearing, the significant change was found in the deafness by using the patch clamp.

钙激活钾离子通道简称BK通道，存在于毛细胞纤毛的底部，是毛细胞电活动重要的离子通道，参与高频听力发生，以往膜片钳的方法证实BK通道在耳聋时电生理功能发生重要改变。

About 4 days post amputation, cells in some areas in the out epidermis and inner parietal peritoneum near the end of the stump are induced by injury to dedifferentiate into stem cells and then proliferate forming stem-cell masses, which then invaginate into the interior dermis. The dermal cells are then induced by those invaginating stem-cell masses to dedifferentiate.

从第4 d起，近创伤处的表皮层和体腔上皮中部分细胞发生了脱分化形成了干细胞，并增殖形成了干细胞团，然后向真皮层内陷，并诱导真皮层组织发生脱分化，最终在残腕体壁的不同部位形成了众多干细胞原基，是进一步再生所需的细胞库。

Using the mechanism of the nuclear reaction of accelerated 7Li +3 ions with the inner target in mutant material i.e 1H( 7Li, 7Be)n, the biological effects were studied. The wheat seeds were irradiated with the doses ranged from 1.416×10 10 ions/cm 2 to 1.416×10 12 ions/cm 2. It was found that the cell membrane ruptured, the plasmolysis occurred, the nucleus shape changed.

将加速器7Li+ 3 离子束与生物体内遗传物质发生1H( 7Li，7Be)n内靶特征核反应诱发核酸分子结构变化的机制应用于生物诱变，辐照剂量在 1 41 6× 1 0 10 粒子 cm2 - 1 41 6× 1 0 12 粒子 cm2范围内处理的小麦，观察幼苗叶片细胞亚显微结构，发现离子束注入引起了细胞膜的破裂，细胞发生质壁分离，细胞核形状变得不规则等。

In fish and amphibia, the transition from maternal gene transcription to zygotic transcription happens during the time of midblastula formation, this stage is named by midblastula transition, at this period, embryo cell cycle composition changes, it is the first time to G1 time appearance, the cell cycle timelimit lengthens and the cell division synchronism loses, the large quantities of zygotic gene transcription starts.

鱼类和两栖类由母型调控向合子型调控过渡发生在中囊胚形成阶段，称为中囊胚过渡(midblastula transition，MBT)，胚胎细胞周期时相的组成在此期间发生变化，首次出现G1期，周期时限延长，细胞分裂的同步性丧失，大批合子型基因活化转录也在此时开始。

It also indicates that the expression of WT1 is regulated strictly in time and space, and the aberrant expression of WT1 may result in retarded differentiation of blastemal cell leading NR or nephroblastoma.

提示在散发性肾母细胞瘤发生中除WT1突变外，WT1表达延迟可能是其中起重要作用的机制之一；WT1基因与肾母细胞瘤的组织分化有关，可能诱导胚基细胞向上皮细胞方向分化。

Usually, anti-apoptotic protein is insulated in organella, restraining the release of pro-apoptotic factor and controlling cell apoptosis. however, interacting with pro-apoptotic protein, it can not restrain apoptosis, induce the loss of mitochondrial function, accelerate the release of pro-apoptotic factor and result in apoptosis.

抑凋亡蛋白平时被隔离在线粒体等细胞器内抑制促凋亡因子的释放，具有抑制细胞凋亡的功能，但一旦与激活的促凋亡蛋白发生相互作用后，便丧失了对细胞凋亡的抑制作用，造成线粒体等细胞器的功能丧失和细胞器内促凋亡因子的释放，导致细胞凋亡。

Anti-apoptotic and pro-apoptotic factors have synergistic effect and play a switch role. Usually, anti-apoptotic protein is insulated in organella, restraining the release of pro-apoptotic factor and controlling cell apoptosis.

抑凋亡蛋白平时被隔离在线粒体等细胞器内抑制促凋亡因子的释放，具有抑制细胞凋亡的功能，但一旦与激活的促凋亡蛋白发生相互作用后，便丧失了对细胞凋亡的抑制作用，造成线粒体等细胞器的功能丧失和细胞器内促凋亡因子的释放，导致细胞凋亡。

However, higher concentration of CRP may increase the expression of protein and mRNA of inflammatory factor in endothelial cells; 2 Higher concentration of CRP may participate in the development of inflammatory process in endothelium by the mechanism that CRP induce cells apoptosis and activate signal pathway involved in cell proliferation. 3 CRP is the member of pentraxins family, in which two faces of pentamer form a special bi-phase structure: one face is ligand recognition phase; the other face is effector phase.

总结： 1CRP是一种保守蛋白，在正常生理水平下对内皮细胞没有明显的诱导炎症发生的作用，仅在高浓度条件下有可能诱导细胞炎症相关蛋白及mRNA的表达； 2高于生理水平的CRP对内皮细胞的致炎作用主要通过诱导细胞凋亡及激活细胞增殖相关蛋白信号通路的表达； 3CRP是一种双面五聚体蛋白，结构具有特殊的二相性，能够分别结合内皮细胞和E-LDL。

The former formed a kind of KR cyst, while the later formed a kind of NKR cyst. All the kinetosomes, ciliary shafts and microtubules were resorbed in the former, meanwhile, the cell lost most water and cell volume decreased distinctly. In the later, only part of kinetosomes and part of microtubules were resorbed. Cell lost water slightly and volume decreased slightly.

期间，细胞吸收了全部的毛基体、纤毛杆和微管结构，伴随着细胞剧烈的失水浓缩，细胞体积显著缩小；游仆虫在形成毛基体非吸收型包囊时，细胞仅经历了部分的脱分化过程，期间，细胞仅吸收了部分的毛基体及部分微管结构，并且细胞仅发生了轻微的脱水和浓缩，细胞以折叠的形式容纳在包囊壁内。

Inthe whole process, the oocytes, nurse cell and follicle cell morphology change. Inoocyte yolk formation and growth, the number of its nuclear trophoblast cell nucleoli,lamphrush chromosome with a strong synthetic material; oocytes also some syntheticmaterial; follicle cells in the yolk protein synthesis, provide access to exogenous yolkprotein.

在卵子发生的整个过程中，卵母细胞、滋养细胞及滤泡细胞形态均有明显变化；在卵母细胞生长及卵黄形成期，滋养细胞核内的多核仁现象、灯刷染色体与旺盛的物质合成有关；卵母细胞本身也合成一些物质；滤泡细胞参与卵黄蛋白的合成，并为外源性卵黄蛋白提供通道。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
