使发育

Subclones of the hybrid 741 took on a high insect-resistant identity to the larvae of leaf pests such as Clostera anachoreta Fabricius, Lymantria dispar Linnacus, Hyphantria cunea Drury ect., and the mean death rate of the grubs were all above the 85%, furthermore, the grubs' growth which survived could be restrained and the growth rate was reduced so that they couldn't tie cocoons as the usual.

项目简介：转双抗虫基因741杨是将部分改造BtCryIAc 基因与慈菇蛋白酶抑制剂基因，通过农杆菌介导法转化了优良白杨杂种741杨，并获得了一批具有高抗虫性无性系，对舞毒蛾和杨扇舟蛾，美国白蛾等鳞翅目幼虫死亡率达85%以上，并能抑制存活幼虫的发育，使其不能正常化蛹。

Diagenesis types include compaction,cementation, solution and metasomasis.

成岩作用类型主要包括压实作用、胶结作用、溶解作用和交代作用，其中胶结作用使储层原生孔隙迅速变差，而溶解作用是次生空隙发育的主要因素。

As a result of its high capability in interception of precipitation and enhanced evaporation of soil surface, the development of microbiotic crusts will more and more threaten the soil water condition which the artificial sand-fixing vegetation should rely on.

微生物结皮的逐年发育使其对降水的拦截能力和地表的蒸发能力都逐渐提高，并改变了水分在土壤剖面中的分配过程和格局，这对人工固沙植被赖以生存的土壤水环境产生了越来越大的威胁。

Regular diet, in addition to containing a large number of animals necessary nutrients, but also contains a certain amount of anti-nutritional factors, these anti-nutritional factors is difficult to digest in the use of sheet monogastric animals, so that intestinal contents became viscous, and wrapped a large number of nutrients, affect the digestion and absorption of nutrients, resulting in animals indigestion, lax and poor growth.

常规日粮中，除含有大量动物必须的营养物质外，还含有一定量的抗营养因子，这些抗营养因子难被单胃动物消化利用，使肠内容物变得粘稠，而且包裹大量的营养物质，影响营养物质的消化吸收，造成动物消化不良，排粘粪，发育不良等。

U 2+, Co 2+ and Mn 2+ whose concentrations were 40, 40, 20μg·L -1 respectively could increase the AKP activity significantly in mysis, but higher con...

o2 +在 2 0μg·L-1时明显提高两种酶的活性。而Ni2 +只使两种酶活性降低。鉴于碱性磷酸酶和ATPase与生长发育直接相关，金属离子对对虾幼体生长的影响与对两种酶活性的影响基本一致，因此体内这两种酶活性的高低可作为判别环境因素是否适合对虾幼体生存的指标。

Now, I mainly engaged in myxobacterial genomic and bioinformatics analysis work. Myxobacteria is a single-cell microorganisms, but they act as multi-cell behavior (such as feeding, social movement, cells congregating and fruiting body formation, and so on) and own a wealth of secondary metabolites Product, those remarkable characteristics make myxobacteria important in the research fields of prokaryotes cell differentiation and development, biological evolution, as well as the drug development and research.

现主要从事粘球菌基因组与生物信息学分析方面的研究工作：粘细菌是单细胞微生物，然而却具有多细胞行为（如摄食、社会性运动、细胞聚集和子实体形成等）和丰富的次级代谢产物，这些行为特征使粘细菌在原核生物的细胞分化发育、生物进化以及药物开发研究中占有重要地位。

The study showed that the incidence of congenital hearing disorder in neonatal born in Tanggu district of Tianjin was nearly 0.1%. DPOAE test is simple and easy for the hearing screening in neonatus, and can detect congenital hearing disorder timely so as to interfere properly.

天津市塘沽区新生儿先天性听力障碍发病率可初步认为是0.1%；采用DPOAE能较简便地筛查新生儿的听力障碍，及早发现有听力障碍的个体，使其在语言发育的关键年龄段之前就能得到适当干预。

Methods: Adherent cells were isolated from peripherial blood samples in asthmatic patients in remission and in healthy volunteers by Ficoll and noncontinuous density gradient centrifugation and were cultured with GM-CSF and IL-4 as immature DC.

分别取缓解期哮喘患者和正常人外周血经Ficoll和不连续密度梯度离心法获取贴壁细胞，经GM CSF和IL 4体外培养为不成熟DC ，加入LPS刺激使其发育为成熟DC。

In addition, it also leads to the increase of T〓 and FT〓 content, the decrease of T〓 and FT〓 content, the increase of TSH content in the plasma, which seriously influences the whole body's growth and metabolism of nutrimental materials and is one of the mechnism of nutritional anemia that is caused by lack of matter of making blood.

首次揭示雏鸡硒缺乏不但对甲状腺造成损伤，而且还特异性地降低肝脏、肾脏等组织中ID-1活性，使血浆3-5-3'-5'-四碘甲状腺原氨酸、游离T〓含量升高，3-5-3'-三碘甲状腺原氨酸、游离T〓含量下降，促甲状腺激素含量升高，严重影响整个机体的生长发育及营养物质代谢，并是导致造血物质缺乏所致的营养性贫血的机理之一。

He experiment proved that pre-implantation embryos are more sensitive than post-implantation ones, suggested TCDD may exert its effect before implantation, or at this process. 3. The toxicity of TCDD on the early embryo can be of omnifarious. It can strongly inhibit DCR, which represent mother toxicity; It cause un-synchronizated cleavage of pre-implanted zygote and pre-implanted embryo loss; It also decreases implantation sites in the uterus, and continued to effecting the uterus of pregnant mouse, cause the decreased number of fetus before birth. 4. TCDD exposure changed reproductive hormone level of pregnant mouse.

CDD对胚胎的毒性影响可能是多方面的：强烈抑制子宫蜕膜细胞反应，表现出典型的母体毒性；虽然没有影响胚胎转运速度，但造成着床前胚胎的丢失和发育不同步；早期染毒降低了第9天的胚胎着床数，同时使出生前第18天胚胎成活数继续减少。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
