Good copies of this gene, which is mutated in many cancers, can force some cancer cells to commit suicide. The effects of p53 could be bolstered with antibodies that slow tumors by attaching to the surface of cancer cells and gumming up their ability to take over the body's growth factors, the specialized proteins that promote cell reproduction.

这一基因的复制品在很多种癌症中产生好的变异,能迫使一些癌细胞自行死亡。p53还可以与抗体一起发挥更大的作用,它们附着在癌细胞的表面,减弱癌细胞将促进细胞繁殖的特别的蛋白质取而代之的能力。

Based on Hutchinson niche and Guangxia Cao\'s definition, Fuzzy hypervolume niche evolves the theory of fuzzy niche: the niche is a fuzzy hypervolume; the niche of the species is a hypervolume with fuzzy boundary which is formed by the n-dimensional resources (time, space, temperature, humid, trophic,...) necessary for the species\' continuous existing and multiplying; membership of a point in the niche is equivalent to the adaptive degree of the species to the point of the environmental resources.

在Hutchinson生态位和Guangxia Cao的定义的基础上,模糊超体积生态位发展了模糊生态位理论:物种的生态位是可以使物种生存和不断繁殖的n维环境变量(时间、空间、温度、湿度、营养……)所形成的边界模糊的一个n维超体积;隶属函数表明n维资源空间的一个点x属于生态位的程度,也表明物种对环境资源的适应程度。

There was a stable and relatively low expression level for Lbα1 and a progressive expression pattern for Lbα8 among the 1st,2nd,3rd,and 4th nymphal stages.5 Development and reproduction of L.decolor as a function of temperatureThe developmental rate,survival,intrinsic rate of increase,net reproductive rate(R_0),mean generation time,and population doubling time of L.decolor population were evaluated at eight constant temperatures.

Lb a1在1龄、2龄、3龄、4龄若虫及成虫中的表达水平分别是Lb a8的2.03、2.55、4.77、6.54、和5.28倍,且它们之间的差异均达到显著水平(P<0.05)。5温度对无色书虱发育和繁殖的影响通过比较无色书虱在不同温度条件下的发育速率、存活率、内禀增长率等生命参数以明确无色书虱在不同温度条件下的发生发展规律。

In this paper, 35 Tupaia blangeri chinensises captured from Kunming,Yunnan province were investigated. We analyzed hereditary conditionality index about some morphological characters. According to Rife-Buranamanas law, We analyzed the appearance characteristics with hereditary conditionality including color of fur, orbit etc.. The results showed the following: wild fur with seasonal red spot, white fur of abdomen, non-white orbit, fleshcolor palm, non-cocked ear, round tip tail, and the line between the breasts of both sides in a vertical position with axis line.

主要以上海市肿瘤研究所购自云南昆明地区的35只中缅树鼩及其实验室条件下繁殖的G1代为试验素材,对涉及形态性状遗传制约性的一些指标进行分析,应用Rife-Buranamanas 定律分析中缅树鼩涉及毛色等诸多具有遗传制约性的外貌特征的显隐性关系,得出中缅树鼩典型的外貌特征为野生型毛色有季节性红斑、白腹、没有白眼圈、掌底肤色为肉色、耳朵不竖、圆形的尾尖、两侧乳房每对之间的连线分别与体轴线垂直。

Roger and co-authors (1993) suggest that in some instances inoculation may be useful, particularly since the inocula produced with high levels of P may have an advantage over P-limited indigenous strains; however, they suggest management practices that enhance the proliferation of native cyanobacteria to increase the N-fixing potential of these organisms.

Roger 和他的合作者们(1993)认为在某些时候接种剂是有用的,特别是高磷条件下培养的菌种对于低磷土著品系来说有一定的优势;但他们建议采用增强固有兰细菌生长繁殖的管理措施以提高这些微生物的固氮能力。

Their saliva has antibacterial properties; it contains lysozyme, an enzyme that lyses and destroys harmful bacteria. Their short digestive tract is designed to push through food and bacteria quickly without giving bacteria time to colonize. The extremely acidic environment in the gut is also a good bacteria colonization deterrent. People often point to the fact that dogs shed salmonella in their feces (even kibble-fed dogs do this) without showing any ill effects as proof that the dog is infected with salmonella.

牠们的唾液有杀灭细菌的功能,其所含的成分可以很快制有害细菌为死地;牠们很短的消化道是的食物和细菌很快的通过,致使细菌没有繁殖的时间;胆道所分泌的高酸性胆汁也使有害菌没有生长的环境;人们也会发现在健康狗狗的排泄物中可以发现沙门氏菌(有些喂食狗粮的狗狗也会有),因而认定狗狗感染了沙门氏菌。

Moreover, the House Index, which gauges mosquito breeding sites, may not be a good indicator of the population's exposure to a virus, says entomologist Paul Reiter of the Pasteur Institute in Paris.

此外,巴黎的巴斯德研究所的昆虫学家Paul Reiter称,计量蚊子生存繁殖的生存指数也并不一定是好的揭示病毒的标志,重要的不是生存地的数量而是成体蚊子的繁殖量。

The numerous macro-plants during the Doushantuoian were branching and semi-floated and erected on seafloor. They advanced the photosynthetic efficiency and increase oxygen in water to improve in environment for metazoans; and they served as a primary producer in the paleoecosystem to provide an alternative and new food of metazoan.

陡山沱期的宏体藻类多分枝并直立固着于海底,提高了光合作用的效率,增加了海中水体中的含氧量,不仅改善了环境,为依赖一定氧而生活、生长和繁殖的后生动物给予了必要的支持,而且作为生态系统中的必要基础,为宏体后生动物的快速发展和演化提供了一个新的食物源。

Scientists at Oregon university argue in Nature magazine that their research with roundworms – which can self-fertilise or reproduce sexually – shows selfing populations are more susceptible to harmful genetic mutations and slow to adapt to swiftly changing environmental conditions.

俄勒冈大学的科学家在《自然》杂志上撰文称,在对既可以自体受精、也能够有性繁殖的蛔虫进行研究后发现,自体受精的后代更容易受到有害基因突变的影响,对迅速变化的环境条件的适应速度也比较慢。

According to the Greek myth, the various levels came to be separated at a later stage, when Jupiter, Neptune and Pluto established their respective rulerships over the visible blue sky, the sea and the underworld controlling the soil and fertility of the material foundation of life on earth (thus Pluto's connection with Ceres and Persephone, goddesses of fertility).

根据古希腊神话,乌拉诺斯至高无上的权力在晚期被分割,木星、海王星和冥王星诸神均建立了自己的统治,他们统治的领域上至可见的蓝天,下至海洋和掌管土壤的地下世界,以及地球上生命的物质基础的繁衍(冥王星也被认为与谷物女神和冥后有关,象征繁殖的女神)。
