查询词典 oogenesis

This work is one of the most important bases of eliminating locusts. Studying the oogenesis of insects has important significance on demonstrating the reproductive mechanism and controlling locusts" fertility. At the same time, it"s an important means of studying the forecast of pests and the law of occurrence. It can reveal the law of ovipositing and explain the physiological basis of pests" occurrence, thus design "biorational insecticide.

研究昆虫的卵子发生对于阐明昆虫的生殖机理和控制繁殖具有重要的实践意义，是研究害虫预测预报和发生规律的一种重要手段，同时可以揭示昆虫大量产卵的规律，阐明害虫大发生的生理基础，从而设计出"生物合理的杀虫剂"，并为促进有益昆虫的大量繁殖提供理论依据。

In different embryo developmental stages, its expression was decline gradually . This result indicated that the survivin may play important role in oogenesis and early embryogenesis. One PABP gene was cloned from the subtractive cDNA library.

RT-PCR分析表明该基因主要在卵巢中表达，随着胚胎发育表达逐渐减少，这可能表明该基因在半滑舌鳎卵子形成和早期胚胎发育中起到重要作用。ePABP是特异的在卵巢和早期胚胎表达的Poly结合蛋白。

According to the size and shape of oocyte, the morphology of nucleolus, the growth of yolk and the structure of follicle, oogenesis of H. d. supertexta can be divided into three stages as follows: oogonium, previtellogenic oocyte and vitellogenic oocyte. The ovary wall is composed of tunica adventitia and germinal epithelium which will produce oogonia and follicle cells. The follicle is the structure unit of ovary.

根据卵细胞的大小、形状，核仁的形态，卵黄颗粒的积累情况，滤泡的结构等，将九孔鲍卵子的发生分为卵原细胞、卵黄发生前的卵母细胞和卵黄发生期的卵母细胞3个时期；卵巢壁由外膜及内生殖上皮构成，生殖上皮分化产生卵原细胞和滤泡细胞；卵巢的结构单位是滤泡。

According to the size and shape of cells,nuclei and nucleoli,and to the NPand the vitelline accumulation,the oogenesis can be divided into five phases:oogonium phase,small growth phase,large growth phase,pro- maturation phase and ma...

卵子发生根据卵细胞、细胞核及核仁的大小形态、核质比和卵黄积累情况可分为：1。卵原细胞期：2。小生长期；3。大生长期；4。成熟前期和5。成熟期。卵巢发育则根据第一批卵细胞的发育情况、卵巢长度及颜色分为五期，大致可归纳为三个阶段：5～7月为延缓期；8～11月为对数增长期：12～4月为稳定期。

The reproductive toxicity of Aroclor 1254 on the oogenesis, the fertilization and preimplantion embryonic in vivo in female mice, the spermatogenesis toxicity, the sperma fertilizing ability and the zygote developmental toxicity in vivo in male mice were studied, and the toxicity mechanism were discussed by histopathological examination of the ovary, the uterus, the testis and epididymides.

以小鼠为动物模型，研究了类二噁英多氯联苯的典型代表物质——Aroclor 1254对母鼠卵子发生、受精和附植前胚胎体内发育毒性，公鼠精子发生毒性，以及对精子受精能力和受精卵体内发育的毒性。

For better understanding of the formation and changes of glycoconjugates during spermatogenesis and oogenesis, the distribution of PNA binding glycoconjugates in the plasma membrane of Adda cinera germ cells have been detected by using biotin labeled PNA.

本文首次采用生物素标记的花生凝集素对中华蚱蜢配子发生过程中细胞质膜的糖蛋白含有糖基Gal-β-(1，3-GalNAC进行了标记，旨在认识配子发生过程中细胞质膜糖复合物的形成与变化规律，探讨其所具有的功能。

The main research achievements on oogenesis and embryogenesis in mammals are described in this review,including the resumption of meiotic division;activation of MⅡ oocyte;development of parthenogenetic,gynogenetic,androgenetic and reconstituted embryos;and the genetic and reproductive potentials of chromosomes within the first and the second polar body.

本研究将论述哺乳动物卵子发生和胚胎发生的最新研究进展，包括：减数分列的启动， MⅡ期卵母细胞的激活，孤雌胚、雌核胚、雄核胚和重组胚的发育以及第一与第二极体染色体的遗传和生殖潜力。

This indicates that CaHIRA plays a definitive role in the development of ovary or oogenesis. In coloreded crucian carp, Cahira gene was expressed in the unfertilized eggs. However its expression decreased dramatically after fertilization. The expression increased again and kept stable from gastrulation till hatching.

成鱼组织中，Cahira在卵巢、脑、心、肝、脾、肾中均有表达，在卵巢和肝脏中表达较强，而在精巢和肌肉中不表达，表明它可能在卵巢发育和卵子发生过程中发挥一定作用。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
