致死性

The decline of the semilethal temperature caused by the changes of membrane protective system was the foundation of rising the cold resistance.

膜保护系统的适应性变化导致低温半致死温度的下降是抗寒性提高的基础。

Semilethal temperature was determined by using Logistic equation fitting for inflection point value.

并用Logistic方程拟合求拐点值来估计其半致死温度，探讨其抗寒性。

Based on the practical experience, methods of the breeding of male silkworm Varietis by sex-linked lethal balancing lines have been expatiated, and it will be benefit to investigators actively exploring and exchanging in the field.

本文在总结实际操作经验的基础上，对利用性连锁平衡致死系进行雄蚕品种选育的方法进行了简要的阐述，有助于科研工作者在该领域内积极地进行探索和交流。

Superficial Thrombophlebitis is a very common vascular disease in the limbs. For the clinical symptoms of this disease are relative slight, people are likely to ignore it. If it is untimely or wrongly treated, it will result in deep vein thrombosis, even death because of the infarction of the pulmonary artery.

血栓性浅静脉炎是临床上常见的周围血管疾病，由于本病临床症状相对较轻，不易引起人们的重视，但若失治误治，可因血栓蔓延侵及深静脉而导致深静脉血栓形成，甚至有肺动脉栓塞致死的危险。

People with a parent who suffers from Huntington's disease are often functionally uninsurable, as they have a 50 per cent chance of carrying a mutation that will kill them unless something else does first.

华父母患有 Huntington 疾病的人通常机能性地不能参保，因为他们有50%的机会带有基因突变，如果先没有采取什么措施，这足以让他们致死。

Methods①The animal model of braincontusion caused by free drop hammer was established.②The injuredtissue of rat brain were stained by TUNEL for apoptosis,immunohistochemistry for Caspase-3 and Feulgen"s for DNA. Image analysistechnique and the statistical method were employed to explorate thetemporal changes of injury time.③The DNA was extracted from ratcontusive tissue of brain and assayed by gel electrophoresis toinvestigate the relationship between the DNA fragmentation and injurytime.④One handred and seventeen cases of death from traumatic braininjury were retrospective researched to investigate the characteristicof TBI in forensic medicine.⑤The contusive tissue of human brain werestained by TUNEL, Caspase-3 immunohistochemistry and Feulgen"s methodsin the same way to analyze and disclose the linear relationship betweentemporal changes with injury time.

方法①建立大鼠自由落体打击脑损伤模型；②对不同损伤时间组的大鼠脑挫伤组织进行TUNEL、Caspase-3免疫组化、Feulgen's DNA染色，结合图像分析技术和统计学分析，探讨脑挫伤后神经细胞凋亡、DNA片段化和含量的时序性变化；③提取大鼠脑挫伤组织DNA进行琼脂糖凝胶电泳分析，观察DNA片段化随损伤时间的变化特点；④对117例颅脑损伤致死案例进行回顾性分析，探讨其法医学特点；⑤选择不同损伤时间的人脑挫伤组织同样进行TUNEL、Caspase-3免疫组化、Feulgen's DNA染色和分析，观察上述指标与损伤时间的关系。

A new picorna-like virus was isolated from dead Evtropis oblique larvae deceased from NPV infection. Electron microscopic observations of purified virions were non-enveloped isometric particles with diameter of 26nm. The virions contain two capsid proteins: 31.5kDa and 28.8kDa, the amount of later is 2.5 times more than that of the former. Analysis of 3′terminal sequence of EoPV clone identified that it can encode RdRp and has eight conserved motifs. Homology analysis shows that it is closely related to Perina nuda picorna-like virus.

从核型多角体病毒感染致死的茶尺蠖幼虫尸体中分离到一株微小RNA病毒透射电镜观察纯化的病毒粒子为无囊膜、无表面特征、直径约26nm的球状颗粒。16%的SDS-PAGE显示它有两个分子量为31.5 kDa和28.8 kDa的衣壳蛋白，后者的含量是前者的2.5倍。3′端克隆序列分析表明EoPV基因组3′有poly尾，编码RNA聚合酶，含有微小RNA病毒RNA聚合酶的八个保守基序，同源性分析表明它与榕透翅毒蛾微小RNA病毒亲缘关系最近。

The two groups were compared for outcomes, including death, retransplant, nonfatal major adverse cardiac event, cardiac function, morbidity, and development of confirmed allograft vasculopathy.

两个样本组相较之下，厚度增加样本组的不良后果，包括致死、再移植、非致命性心脏病、心脏功能、病态，与被确诊的同种异体移植血管疾病的发展。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
