查询词典 escape

Some sperm with damaged DNA may escape from the sperm surveillance mechanism and transmit the damage to the offspring.So research on the damage to sperm DNA has become one of the hot spots in reproductive medicine.

替代组蛋白成为精核蛋白的鱼精蛋白和大量的二硫键使精子染色体高度压缩，这种特化的结构可以保护精子DNA免受伤害，因此成熟精子对各种致病因素有较强的抵抗力。

"This is an important point," Dr. Sawyers told Medscape in an interview,"as it shows that the drug target continues to mutate and that BCR-ABL is the escape mechanism." Hence, further drug development should continue to focus on BCR-ABL and not on any of the other mechanisms that are thought to also be involved, he commented.

Sawyers医师在一项访谈中向Medscape表示，这是个重点，当这项研究显示药物的标的持续在突变，且BCR-ABL基因有逃脱机转，他评论，之后的药物研发应该继续针对BCR-ABL且不应针对其他被认为牵涉其中的机转。

The UL149 gene encoded product from jaundice infants infected with HCMV might combine with human cytomegalovirus IE UL37 protein or glycoprotein B, and might be involved in immune escape mechanism.

在黄疸患儿感染的人巨细胞病毒UL149基因编码产物可能与人巨细胞病毒的gpB、立刻早期基因UL37等具有联合作用，并且可能参与HCMV的免疫逃避机制。

In conclusion, our results demonstrated that intratumoral electroporation-mediated IL-6 and IL-15 gene therapy for canine transmissible venereal tumor in the canine model efficiently tumor escape mechanism and also intensified the host immune responses.

以上这些结果显示使用肿瘤内电冲，进行IL-6与IL-15基因治疗，在实验犬模式，可成功破坏肿瘤逃避免疫系统的作用并提升免疫反应，达到成功治疗肿瘤之目的。

Compared with classical cytotoxic T lymphocytes , NK cells are superior in the following aspects: NK cells are among the first cell types to be activated after intracellular pathogen stimuli, the activity of NK cells peaked between 1 to 3 days, retained during the first 7-10 days, and the T cells response emerged only after 7 days when the NK cell responses begin to decline; though comprising of only 10％-15％ of peripheral lymphocytes, NK cells mobilize most of the cell populations in a strong and high level response to different invasions, and act as key factors at early defense before a specific immune response could mount, while only certain clones were involved in T cell response; NK cells kill virus-infected or malignant transformed cells without pre-sensitization and without restriction by major histocompatibility antigen, which is usually a mechanism of immune escape to T cell recognition by virus-infected or tumor cells, thus NK cell in complementary with T cells play crucial roles in tumor and virus eradication.

NK细胞以其强大的细胞毒活性为特征，与细胞毒性T细胞相比，NK细胞具有如下特点：NK细胞虽然只占外周血淋巴细胞的10-15％，但是对刺激性因素产生应答的过程十分迅速，一次可以调动大多数细胞共同参与，而不是几个克隆的活化，免疫应答的强度高；病毒感染或恶性转化细胞的一个主要特征是细胞表达的MHCⅠ类分子下降或消失，并借助这一机制逃避特异性T细胞应答的识别，NK细胞介导的杀伤活性无需抗原刺激，不受MHCⅠ分子表达的限制，从而与T细胞应答互为补充发挥免疫防御的功能；NK细胞的免疫活性可以被多种细胞因子上调，其中IFNα，IL-2，IL-12，IL-15和IL-18具备更强的作用；NK细胞具有强大的细胞因子分泌功能，对于启动T细胞特异性应答必不可少。

That's a strengthened version of individual escape velocity.

那是一个个体逃逸速度的增强版。

You'll never hit escape velocity.

你永远无法达到逃逸速度。

So, the 10% per year rate of progress is what I've started to call "escape velocity".

所以，每年10 ％的进步速度，我开始称之为"逃逸速度"。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
