细胞毒素的

The research lays a fundation for revealing the pathologic and antitoxin mechanism on the cell level.

本研究为揭示毒素在细胞水平的致病机理及寄主抗毒素的机理奠定了一定的理论基础。

The cDNA has 752bp and encodes a protein of 216 amino acids. Thenascent Src l contained a signal peptide of 19 amino acids, a propart of 19 amino acidsand a 178-amino-acid mature Src l. The characteristic amphiphilic α-helix of cytolysin islocated at the N-terminus of the mature Src l.

根据文库的EST序列设计引物，从玫瑰红绿海葵克隆到一全长cDNA序列，命名为Src I，利用生物信息学方法对其进行了分析，结果表明，该cDNA序列编码一个216个氨基酸的海葵细胞毒素前体蛋白，它包括19个氨基酸的信号肽、19个氨基酸的propart motif和178个氨基酸的成熟蛋白。

New strategies for breeding seedless plants have been proposed by using these genes. These include expression of some cytotoxin genes or genes for production of hormones in plants under the control of seed_coat_specific promoter or ovary_specific promoter and "terminator technology" etc. It's clear that these transgenic methods will be introduced into a wider range of fruit and vegetables in the future.

应用这些目的基因，已建立了转基因生产无籽果实的新策略，如在种皮或子房特异性启动子控制下的生长素基因或细胞毒素基因的表达及"终止子"技术的运用等，这将大规模地促进蔬菜和水果生产，提高果蔬产品的市场价值。

After the cells were treated by high concentration toxin for 4d, the content of nitrate-nitrogen in cells were lower markedly than the contrast, after the cells were treated by middle and low concentration toxin for 7d, the content of nitrate-nitrogen in cells were lowered. 3 groups of toxin treating all lowered the total phosphorus content. At the end of test, the phosphorus contently of low, middle, high concentration treating groups were 74.98%, 76.47% and 84.00% of the contrast respectively. The ACP activity of 3 treating groups compared with the contrast appeared the tendency of first lowering then raising.

高浓度毒素处理细胞4d后，细胞内硝态氮含量显著低于对照；中、低浓度毒素处理细胞7d后降低了胞内硝态氮含量。3组毒素处理均降低了胞内总磷含量，到实验结束时，低、中、高浓度处理组的胞内磷含量分别为对照的74.98%、76.47%和84.00%。3组处理组ACP活力与对照相比呈现先降低后升高的趋势。

The type of cell death caused by ricin was related to the ricin concentration and time of incubation with HeLa cells. The typical apoptosis was induced by ricin 0.05μmol〓. The apoptotic cells mainly showed cell shrinkage, cytoplasmic membrane blebbing, the chromatin condensation and fragmentation, crescentic nuclear and membrane bound apoptotic bodies formation.

细胞死亡方式也与蓖麻毒素作用时间和浓度相关，0.05μmol.L〓的蓖麻毒素可引起HeLa细胞发生典型的细胞凋亡，主要特征是细胞体积缩小，胞浆起泡，细胞核染色质浓缩、凝集，新月状核和膜包裹核染色质的凋亡小体形成。

In the past twelve years there have been hundreds of studies showing these nonthermal effects--- such as DNA damage and nonrepair, opening of the blood-brain barrier (allowing toxins and pathogens to reach the brain), lowered immunity, decreased melatonin levels, effects on stress proteins, formation of micronuclei (aberrations in cell nuclei which are often markers for cancer), changes in calcium metabolism affecting communication between cells, changes in brainwave patterns as seen on EEG's, plus effects observed on many different systems of the body.

在过去十二个月里，已有数以百计的研究表明这些非热效应---如DNA损伤和nonrepair ，开放血脑屏障（允许毒素和病原体到达大脑），降低免疫力，降低褪黑激素水平，对应激蛋白，形成的微（畸变细胞核往往是癌症的标志），改变钙代谢的影响细胞之间的沟通，改变脑电波模式脑电图上看到的，加上效果观察许多不同的系统的机构。

This leads to a buildup of toxins and cells that are not fed the right amount or detoxified properly.

这会带来毒素的积累，也带来没有得到适量营养或恰当解毒的细胞的积累。

Love the skin you are in - goes the song, All of our Natural Deodorants, Cosmetics, and Nutritional Supplementations should keep your whole body from accumulating the various Toxins that are absorbed and go right to the cells.

爱你的皮肤在-不用的歌曲，我们所有的天然除臭剂，化妆品，营养Supplementations应让您的整个身体从累积的各种毒素的吸收，进入细胞的权利。

Alcohol, the most common cause, is a hepatotoxin that interferes with mitochondrial and microsomal function in hepatocytes, leading to an accumulation of lipid.

乙醇是最常见的病因，作为肝毒素能阻碍肝细胞内的线粒体和微粒体的功能，导致脂质沉集。

A concentration of 2.5 micrograms per millilitre was effective at reducing the acrylamide-induced ROS production, as well as the preventing the fragmentation of DNA, and effects of cytotoxicity, report Cao and co-workers.

曹及其同僚表示，浓度为2.5微克/毫升的姜黄色素就能有效的减少由丙烯酰胺引起的活性氧自由基的产生，从而可以防止DNA的裂解，同时有效阻止细胞毒素。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
