To better understand the roles of LsrA protein in nodulation, a series of analyses of nodules using scanning electron microscopy, genetic and biochemical approaches have been carried out. Our analyses suggest that the lsrA1 nodules contain bacteroids in the invasion and establishing zone only. The lsrA gene expression is active early in the invasion zone and activated later than bacA genes. The lost of LsrA protein dramatically reduced the expression of nifA and fixK, and completely blocked the expression of the nifH gene for nitrogenase. LsrA protein functions early in the bacteroid development and it is essential for the development nitrogen fixing bacteroids.

前期的工作中，苜蓿中华根瘤菌Rm1021中90个候选LysR基因已经被定向插入突变，并筛选在自生生长时期、共生生长时期的表型，以期寻找更多在自生状态或共生固氮中有功能的LysR转录因子。1 针对前期鉴定出的共生固氮必需的lsrA基因，我们应用了一系列扫描电子显微镜技术、生物化学、分子遗传学等方法，发现lsrA基因主要在根瘤侵染区开始表达，表达时序也在侵染阶段左右，但晚于bacA基因表达；LsrA蛋白缺失后根瘤固氮区中缺乏具有固氮能力的类菌体，nifA和fixK基因的转录水平降低，nifH基因的转录被完全阻断，因此LsrA蛋白为根瘤发育所必需，是新的根瘤发育信号传导途径成员。2 通过表型筛选我们鉴定了苜蓿中华根瘤菌的oxyR基因，并研究了它的调节特性。oxyR突变后，苜蓿中华根瘤菌对过氧化氢敏感性提高，适应性降低。

Large numbers of experiments internal and external had confirmed both direct current and square pulse of distal end cathodal could improve peripheral nerve regeneration, because it could speed up transmigration, creeper, growth and development of cell Schwann, derivate growth of nerve fiber; it also increased blood capillary of epineurium, brood blood vessel, amendment ischemic of impaired nerve, it still could accelerate Wallerian

国内外大量的基础实验及临床研究都证实远端负极电流的直流电场及脉冲电场等均有促进周围神经再生的作用，认为其可加速Schwann细胞的游走、爬行及生长发育，诱导神经纤维的生长；电刺激还能促使神经外膜毛细血管数量增多，扩张血管，改善神经损伤段缺血状态，并加速Wallerian变性及崩解组织的清除，为Schwann细胞发育和髓鞘化过程提供充足的能量与物质，同时为神经轴突的再生提供良好的内环境；在神经断端出现瘢痕或神经瘤时，电刺激可增加神经纤维穿越瘢痕的能力。

Drying was important for the acquisition of germinability, and drying induced precocious maturation and played some role in the transition from a development programme to a programme oriented towards germination and growth.

干燥脱水对种子萌发有重要意义，成熟脱水可以使种子由发育状态转向萌发状态，玉米种子在获得耐脱水能力之后，干燥可以使未熟玉米种子提前进入成熟状态，终止与发育有关的代谢，开始与萌发有关的代谢。

Results Loss or most loss of competence to defense sexual invasion were often observed in youth patients with chronic-he bephrenic type schizophrenia, moderate mental retardation, and in itial hypomania.

目的研究女性精神病人性防卫能力的特点和司法鉴定中应该注意的问题；方法对过去10年间鉴定过的64例案例进行回顾总结；结果性防卫能力丧失最常见于年轻的衰退期青春型精神分裂症病人、中度以上精神发育迟滞病人、首次发病的年轻轻型躁狂症病人，而其他类型的精神病人不容易发生性防卫能力丧失。

In the period of Mesozoic-Palaeozoic, Caledonian events and the evolution of Hercynian -early indo-Chinese cycle are experienced in two-phase marine passive continental margin and Craton basin in the lower and middle Yangtze Region, by which stable enormous thick Mesozoic-Palaeozoic deposites are induced, six sets of source rocks are produced, it has a strong capacity of hydrocarbon generation.

通过构造演化特征分析了海相烃源岩的发育，中、下扬子区中－古生代经历了加里东和海西－早印支旋回两个阶段的海相被动大陆边缘和克拉通盆地演化，形成了岩性稳定的巨厚中－古生界，发育了6套烃源岩，具有较强的生烃能力。

These results suggest that growth, development and population dynamics of the beet armyworm must be significantly affected by larval diets.

这些结果表明，幼虫食物对甜菜夜蛾的生长发育、产卵及飞行能力均有显著的影响，因而是影响其个体发育、种群增长及种群动态的重要因素之一。

It may be because the external ear dysplasia caused by hearing impairment, such as cochlear dysplasia, are curable by surgery; if it is caused by nerve connection, you need not worry too much pessimism and 宝宝 are still very small, in the infancy of the metabolic capacity of a strong , has many defects can be improved through its own, this is Doctor allows you to review the causes of each month.

它可能会因为外耳发育不良引起的听力障碍，比如耳蜗发育不良，是可以通过手术治愈的；如果是神经方面引起的，您也不用太悲观，宝宝还小，在婴儿时期的代谢能力很强，有很多缺陷都是可以通过自身完善的，这也是医生让您每月复查的原因。

These observations show that reprogramming is easier in interspecific embryos reconstructed with ES cells than that reconstructed with somatic cells, and that ES cells have the higher ability to direct the reconstructed embryo development normally than fibroblast cells. Oocytes were reconstructed with outbreeding Kunming albino mouse ES cells and enucleated rabbit oocytes, and the effects of the passages of ES cells and 6-DMAP on the development of interspecific reconstructed oocytes were analyzed. The interspecific reconstructed ES-rabbit oocytes were activated either by combined two set electric pulses and 6-DMAP or by two set electr

以上结果显示，6－DMAP能增加胚胎干细胞异种重构卵的卵裂率，对重构卵囊胚的发育率影响不大；高培养代数和低培养代数的胚胎干细胞用于异种核移植不影响异种重构卵的卵裂率和囊胚发育率；用胚胎干细胞作为供核细胞；比体细胞作为供核细胞所构建的异种重构胚更容易进行重编程，并且胚胎于细胞指导异种克隆胚胎正常发育的能力强于体细胞。

The result of study shows: Compared with contrast group, the leaf glucoside of the ginseng can promote chickens to resist the production of NDV antibody; The leaf glucoside of the ginseng has facilitation to the development of the pigeon breast gland, have inhibition on the development of chickens spleen, Different influence of bursa because of different way when giving the medicine; Ginseng leaf glucoside can formed ability of nucl

研究结果表明：与对照组相比，人参叶皂武能促进鸡杭NDV杭体的产生；人参叶皂武对鸡胸腺的发育有一定的促进作用，对鸡脾脏的发育有一定抑制作用，对法氏囊的影响由于给药方式不同而异；人参叶皂武能使鸡单核一巨噬细胞系统吞噬能力增强。

Those female mental disorders should be taught as well as receive training of certain knowledge of sexuality, living ability and self-defensive ability against sexual assault.

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
