查询词典 cleaved

Addition of 3μg/ml CB to CM containing 0.625μg/ml CHX increased the proportion of oocytes with two pronuclei (38. 9% vs 15. 1%, P＜0.05) and developed into morulae/blastocysts (40.7% vs 26. 8%, P＜0.05), but did not affect the percentage of oocytes cleaved and total pronucleus rate.

如果在含有0.625μg/ml CHX中添加3μg/ml CB，可明显提高双原核的形成率（38.9％vs 15.1％，P＜0.05）和桑椹胚/囊胚发育率（40.7％vs 26.8％，P＜0.05），但对其激活分裂率和总原核形成率无明显影响（P＞0.05）。

So we propose that before the precursor is cleaved into DG and mediator, it is released from plasma membrane first, through activating some kind of enzyme by insulin or PIPLC; meanwhile, only insulin can activate the resynthesis mechanism of the precursor, in the contrast, PIPLC was inactive at this course.

推测：胰岛素或PIPLC作用于完整细胞或膜时，激活了某种酶，使前体先从膜上释放至胞外，再被水解为介体和DG，同时胰岛素还能激活再合成前体的机制，而PIPLC却不能。

The strip cleaved the communion rail in two and then crossed the entire width of the church, finally reaching the corner of the north transept, where it arrived at the base of a most unexpected structure.

铜条横贯教堂，将纵向的走道截为两段，最终延伸至教堂北翼的角落。在那个角落，树立着一座碑，这让人颇感意外。

Second, aminolysis of polystyrene and poly prepared by reversible addition-fragmentation chain transfer polymerization was investigated. The product of the former contains predominantly double molecular weight species by the formation of disulfide bond, whereas the latter formed coupled species which consequently cleaved to unimolecular weight species.

由RAFT聚合的机理可知，聚合最终得到的聚合物的结构包含双硫酯基团，它是聚合物链保持活性特征的重要体现，同时它为聚合物的端基官能化提供了一个重要的途径，其中氨解反应是一个被人们广泛采用的方法，它在很温和的条件下将端基去掉，同时还能将双硫酯端基变成硫醇端基。

The possible pathway of ABAS degraded by Zoogloea HP3 was that ABAS was first cleaved to produce o-phthalic acid and products. The former was further degraded and the composites of the latter were 2-amino-3-hydroxyl-5bromobenzenic sulfonic sodium and 2, 3-dihydroxyl-5-bromobenzenic sulfonic sodium.

动胶菌HP3作用下溴胺酸可能的降解途径为蒽醌环开裂生成中间产物邻苯二甲酸，邻苯二甲酸被进一步降解；溴胺酸降解后的最终产物为2-氨基-3-羟基-5-溴苯磺酸钠和2，3-二羟基-5-溴苯磺酸钠。

Transformation into active enzymes occurs as one or more peptide bonds in the zymogen are cleaved.

活化作用即是打断原分子内的一个或多个键。这作用受不同的催化或受的活化型本身的催化。

Three thousand of them are bloodied and cleaved.

其中有三千人浑身是伤。

The author found that the chromone ring could be cleaved at high temperature in PPA, and the change of the ratio of ring-opened product versus the target one with the change of reaction time and temperature was investigated in details.

我们采用了两条不同的合成路线合成了第Ⅳ类化合物，对部分反应条件进行了优化，在研究过程中发现了色酮化合物在高温下的开环反应及多聚磷酸的水解作用，并对前者进行了详细研究了，获得了不同反应温度和时间下未开环产物和开环产物的比例，得到了制备相应的未开环产物和开环产物的最佳反应条件。

In addition, a metabolic inhibitor, actinomycin D has no effect on enzymatic activities of caspase-1/ICE-like and caspase-3/CPP-32/like proteases during Fas-mediated CD4〓T cell apoptosis. These results indicate that the appearance of caspase-1/ICE-like and caspase-3/CPP32-1ike proteases activities is a post-translational activation of these proteases. It is likely these caspases constituently express in a inactive form in the cytosol of CD4〓T lymphocytes. Once the rest SEB-responsive CD4〓T cells are restimulted, those inactive caspases such as caspase-1/ICE-like and caspase-3/CPP32-1ike proteases are sequentially cleaved to become active forms, and the apoptotic signal is transducted to downstream signaling molecules, Finally leads to CD4〓T cells apoptosis.

另外，通过代谢抑制剂放线菌素D对超抗原SEB诱导静息SEB应答〓细胞凋亡过程中Caspase成员酶活性变化的研究表明Caspase-1／ICE样，Caspase-3／CPP32样胱氨蛋白酶并非新合成的信号分子，很可能以无活性方式组成性表达于静息SEB应答〓细胞胞浆，在超抗原SEB再次刺激诱导〓细胞凋亡早期，先后顺序活化，借以传递凋亡信号到下游信号分子，诱导〓细胞凋亡。

Interestingly, a diluted dodecane gel of compound 2bdeposited by spin-coating on freshly cleaved HOPG leads toself-assembly of molecular fibers that follow mainly thepreferential crystallographic directions of the underlyingHOPG substrate (Figure 5c).
