查询词典 lethality

In mammals, the Notch signaling pathway is critical for embryonic development, as targeted disruption of Notch1 or its downstream transcription factor RBP-J in mice resulted in disorganization of somites and delayed closure of neurotube, which finally leads to early embryonic lethality.

Notch信号途径在哺乳动物的胚胎发育中起着关键的作用。

The .22LR cartridge offers low noise, low probability of ricochets, and good lethality - of cause, when fired into the lethal area of the body.

轻铁的。22墨盒提供了低噪音，低概率的跳跃和良好的杀伤力时进入人体造成致命的地区发射的，-。

That new direction is "synthetic lethality" via the inhibition of poly(adenosine diphosphate –ribose) polymerases, or PARPs.

这个新方向就是通过抑制多聚聚合酶或PARP 的&合成致死性&。

Ata28 strain was mutated by UV with the most optimum mutant time, including 10, 20, 30s, that was chosen by the trial tests, considering the lethality rate and positive mutation rate of Ata28; it was found that 15 mutant strains were shown antagonism against Tbs3 strain by antagonism test on PDA plate, inhibition zone of mutant strains exceeded the original strain Ata28, and the maximum of inhibition zone reached 9.4mm; the mutant strain Uv-126 was found most effective in tobacco brown spot control and a rate of efficiency control reached 52.2% on tobacco plants three days after bacteria spraying.

采用硫酸二已酯诱变Ata28菌株，通过预备实验，计算Ata28菌株在不同诱变时间的致死率和正变率，选择该菌株的最佳诱变时间20min，40min，60min诱变；通过平板对峙培养，筛选出17个突变菌株在PDA平板上可明显抑制Tbs3的生长，抑菌带高于出发菌株Am28，抑菌带最大值达10.5 mm；经温室控病初筛和复筛试验，获得了对烟草赤星病有较好防效的突变菌株Des-66、Des-50，烟苗经Des-66、Des-50菌液处理3d后，接种Tbs3的防治效果达52.0％、56.6％，比出发菌株Ata28的防治效果好。

For example, it might soon be possible for microbiologists to design and produce special pathogens of enhanced lethality, heightened resistance to medical treatment, predictable or controllable effects, or even the ability to infect people selectively, according to specific genetic characteristics.

例如，微生物家们不久可能会研制生产出一些特殊的病原体，它们具有更大的毒性、更强的抗药性，其作用可被预测或控制，甚至还会根据专门的基因特点有选择地感染人群。

Foods high in this vitamin include oily fish such as salmon, tuna and, and fish liver oils.

维生素D含量高的食物包括诸如大麻哈鱼、金枪鱼和鲭鱼之类的油鱼以及鱼肝油。
