查询词典 ricin

The chemical analyst confirms that the first is indeed ricin, a poison 6,000 times as toxic as potassium cyanide (ricin was in fact discovered in Senate offices on 3 February). The second, supposedly found in Senator Kerry's office, is "botox".

那位化学分析师确认了第一份样品是蓖麻毒，这是一种毒性为氰化钾6000倍的毒素（实际上，蓖麻毒是于2月3日在参院发现的）；而第二份样品则是肉毒素，据说是在参议员克里的办公室里找到的。

The research aimed to discuss the feasibility of taking ricin as raticide and the effects of defatting with different solvents on the biological activity of ricin.

探讨蓖麻粗毒蛋白作为灭鼠药的可行性以及不同溶剂脱脂对蓖麻粗毒蛋白的生物活性的影响。

The retrotranslocation way of Ricin in cell is reviewed in this article.

本文就Ricin在细胞内的逆向转运途径作一综述。

So, it is very important to further comprehend the retrotranslocation way of Ricin in cell in order to get better application in clinical practice.

研究Ricin在细胞内的逆向转运途径有助于其在临床应用中更加完善。

But they are not specific owing to their ability to bind non-target eukaryotic cells through the B chain of ricin.

近期研究表明，ricin的毒性作用除可抑制核糖体外，还能诱导人外周血单核细胞产生TNF-α和IL-1β〔2〕。

The biological activities of ScFv obtained from 293T cell culture fluids infected by liposome were evaluated. RESULTS: The accession number of VH and VL genes of antiricin neutralizing monoclonal antibody was DQ389248 and DQ389245. ScFv could bind with ricin specifically. Inhibition percentage of culture liquid of 293T cell without dilution and with 2 times dilution was 33.7% and 29%, respectively. ScFv could neutralize the cytotoxic effects of ricin to SP2/0 cells at the concentration of 0.01-0.005 ng/mL in a nice doseeffect relation.

结果： 中和性单抗杂交瘤细胞4C13轻、重链可变区基因在GenBank中的登录号为DQ389248和DQ389245，ScFv与ricin可特异性结合，培养上清原液和2倍稀释液的抑制率分别为33.7%和29%；ScFv在ricin浓度为0.01~0.005 ng/mL时可中和ricin 对SP2/0细胞的细胞毒，随着ricin浓度逐渐增大，细胞存活率逐渐减低。

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。

We may well explain why ricin-induced apoptosis showed no typical DNA ladder. The presence of laddering in DNA gels implies an apoptosis process, but its absence does not rule out the apoptosis. The ricin 0.05μmol〓 had no effect on the 〓 phase of cell cycle, but induced 〓 arrest. The ricin may affect the balance of synthesis and destruction of proteins that controlling the cell cycle.

检测到DNA梯度表明细胞发生了细胞凋亡，未检测到DNA梯度不能否认凋亡的存在。0.05μmol.L〓的蓖麻毒素对HeLa细胞周期的G〓/G〓期无影响，而诱导了G〓/M期阻滞，蓖麻毒素可能引起一些控制细胞周期蛋白的合成与降解发生紊乱。

The research aimed to discuss the feasibility of taking ricin as raticide and the effects of defatting with different solvents on the biological activity of ricin.

［目的］探讨蓖麻粗毒蛋白作为灭鼠药的可行性以及不同溶剂脱脂对蓖麻粗毒蛋白的生物活性的影响。

Defatting with different solvents had no effect on the activity of ricin, but the average lethality of the ricin obtained from defatting with methylene chloride was relatively slowly.

采用不同溶刺脱脂对蓖麻毒蛋白的活性没有影响，但二氯甲烷脱脂的蓖麻粗毒蛋白平均致死速度相对较慢。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
