卵子的

Although several gametogenesis-specific genes were identified previously, more genes related to the ovarian development are expected to be involved due to the complexity of gametogenesis.

虽然已有一些调控卵子生长和卵泡发育的特异性基因被发现，但与卵巢发育和卵子生长相关的更多基因的功能有待于进一步研究，阐明其在这复杂过程中的具体分子机制。

The oogenesis of P. esculenta can be divided into the following phases in morphological characteristics of oogonium and oocyte development: the proliferative phase of oogonium (0μm in diameter), the initial growth phase of oocyte (10—20μm in diameter), the grand growth phase-Ⅰof oocyte (20—60μm in diameter), the grand growth phase-II of oocyte (60μm×70μm to 120μm×145μm in size), the mature phase of oocyte, and the declining phase, showing a dynamic changes in oogenesis of P. esculenta .

以卵原细胞与卵母细胞发育的形态学特征为依据，将可口革囊星虫的卵子发生过程划分为：卵原细胞增殖期(卵径0μm)、卵母细胞小生长期(卵径10—20μm)、卵母细胞大生长期Ⅰ(卵径20—60μm)、卵母细胞大生长期Ⅱ[大小为(60μm×70μm)—(120μm×145μm)]、卵母细胞成熟期及退化期6 个阶段，反映了可口革囊星虫卵子发生过程的动态变化。

The process inoles creating an animal not from egg and sperm but by placing the nucleus of a cell inside an egg that's had its nucleus remoed.

一个生命体本来是从卵子和精子的结合开始的，但是克隆技术是将一个细胞的细胞核放置到一个去细胞核的卵子中。

That's far too many if one hopes to use human unfertilized eggs, which are cumbersome to obtain from women.

如果有人希望使用人类的未受精卵产生干细胞，那么这需要的卵子实在太多了。如果这些卵子从妇女身上获取那么将会非常的繁重。

In this thesis, we find that dlg is indispensible in the establishment of anterior-posterior and dorsal-ventral polarity of drosophila oocyte. Removal of Dlg function from the posterior follicle cells using the FLP/FRT system leads to disruption of oocyte skeleton reconstruction that is elicited by the failure of those posterior cells to differentiate normally in mid-oogenesis. We demonstrate that abnormity of Notch, JAK-STAT and EGFR signal pathway in dlg mutants contributes to this aberrant differentiation. dlg null mutant also blocks the normal differentiation of two groups of anterior follicle cell-stretched cell and centripetal cell, but not border cell, with a lower penetrance. However unlike the result in posterior follicle cells, Notch and JAK-STAT signaling are both undisrupted in all mutant anterior follicle cells, implying other fate determinants may be involved.

我们的研究发现，后端滤泡细胞中的Dlg在果蝇卵子发生中期卵母细胞前后轴和背腹轴建立过程中也是必须的，PFC中dlg完全缺失型突变引起PFC的分化异常，导致卵子发生中期卵母细胞骨架重组异常，Stau、Grk等极性决定蛋白定位错误。dlg突变阻碍了Notch、JAK-STAT、EGFR等调节PFC分化的信号通路的激活。dlg突变的PFC也没有获得前端滤泡细胞命运。dlg突变不影响前端滤泡细胞群中边界细胞的分化，但是在一定程度上影响伸展细胞和向心细胞的分化，并且这种影响不依赖于前端滤泡细胞Notch或JAK-STAT信号激活的异常。

Methods patients were divided into general anaesthesia group(propofol intravenous injection'80 cases)and local anaesthesia group(dolantin intramuscular injection+lidocaine uterosacral block'80 cases)randomly. the effects of anaesthesia'heart rates and oocyte retrieval rates were evaluated.

一直以来经阴道穿刺取卵是许多患者比较担心和恐惧痛苦的问题，为了减轻患者的恐惧心理负担及避免卵子被污染、丢失和缩短卵子在不利环境中暴露的时间，目前取卵术常在麻醉下进行，其方法有两种：异丙酚（propofol，pro）静脉推注和度冷丁肌肉注射+利多卡因宫颈旁阻滞。

It is the bearing rules and common senses having been recognized by human beings for a long time, that only during the ovulation period and after the sexual behavior, can the sperm and ovum can meet and can ovum be fecundated.

人类生育有效性交，是在女性排卵期。只有在女性的排卵期，男女合房性交，男性的精子和女性的卵子才相遇，女性卵子才能受精，这是早已被人类认识了的生育规律和常识。

With so many different creatures leaving eggs lying around waiting to be fertilised, perhaps it is not surprising that an occasional misfertilisation takes hold and produces something totally unexpected.

随着许多不同的有生命的活体把它们的卵子扔在海洋里的各个地方去等待受精，也许这并不奇怪，一次偶然的卵子接受了别的物种的精子，产生了完全意想不到的某些生物品种。

By three days after injection, the number of embryos which had cleaved to the 2-cell stage was 0 with round spermatids and mree(17.6%) with elongated spermatids.

结果在培养的 3 d中，ROSI的卵子没有发生卵裂，＆ ELSI的卵子中有 3个服至 2细胞期O7.6O）。

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
