发育能力

Methods: Human mature oocytes were cryopreserved using cryoleaf. Resuscitated oocytes were administered by intracytoplasmic sperm injection, embryo transplantation or cultured to blastulation, observing the fertilization and developmental capacity of oocytes.

运用cryoleaf进行人类成熟卵母细胞玻璃化冷冻保存，复苏后行胞浆内单精子注射-胚胎移植或培养至囊胚形成，观察复苏后卵母细胞受精及发育能力。

The correlative analysis was done between PAIs and postoperative outcome. Results: The minimal diameter of right pulmonary artery was found at proximal portion in 62 cases, at middle portion in 22 cases and at distal portion in 34 cases; the minimal diameter of left pulmonary artery was found at proximal portion in 46 cases, at middle portion in 13 cases, at distal portion in 59 cases. The length of stay in ICU, mechanical ventilation time, dose of inotropic drugs correlated well with modified pulmonary artery index better than Nakata index, with Nakata index better than McGoon index.

目前临床上多用McGoon指数、Nakata指数作为形态学指标评估肺血管容量及肺血流情况，一般认为McGoon指数、Nakata指数越大，术后低心排发生率越低，生存率越高，但这些指数有以下缺点：l 左、右肺动脉第一分支处的单点测量值能否反映肺血管的全貌尚有疑问。2 McGoon指数、Nakata指数无法预计术后肺血管的潜在发育能力。3 McGoon指数、Nakata指数都需通过心血管造影后测量获得，价格昂贵，有一定的创伤性，无法系统观察。

But there are many different viewpoints on the relationship between the apoptosis of granulosa cell and the oocyte developmental competence.

但是，关于颗粒细胞凋亡与卵母细胞发育能力之间关系的研究尚存许多矛盾。

The preimplantation development competences of somatic cell nuclear transfer embryos reconstructed with enuleated goat Metaphase II oocytes matured in vivo and whole cells derived from adult fibroblasts of several mammalian species (goat, boer goat, bovine, tahr, panda) and human patient were evaluated.

研究去核山羊体内成熟的M II期卵母细胞与异种成年的哺乳动物(包括山羊、波尔山羊、牛、塔尔羊、熊猫)及人的成纤维细胞融合形成的体细胞核移植胚胎着床前的发育能力。

N l male gamete transmission of trisomic 2,7,9 had the relation with chromosome behavior at meiosis and with the degression of pollen activity.Besides,n l male gamete fertilization ability and 2n l embryo development ability perhaps could influnce it,too.

6.2号、7号、9号三体n 1雄配子传递率与减数分裂过程中染色体的行为和花粉生活力的降低有关，同时，n 1雄配子受精能力、2n 1胚发育能力可能也会影响n＋l雄配子的传递率。

The rate of Flow cytometry to analyse retinoic acid haploid is 19.3%.The sperm-like cells achieved could activate bovine oocytes by sperm injection, and the development rate of blastosphere was 20.36%. Conclusions SSCs of newly -born mice can be induced and differentiated into sperm-like cells and are also capable of activating oocytes.

本实验通过体外诱导新生小鼠SSCs分化为精子样细胞，探讨不同诱导方法的诱导效率；采用显微注射法将精子样细胞注射到卵母细胞和去核卵母细胞，探讨其体外重构胚的发育能力，为SSCs体外分化研究打下基础。

In conclusion, either electrofusion parameter or developmental stage of donor embryos have a significant effect on the efficiency of NT, NT embryos require different concentration of serum at their different development stages.

结果表明，电融合参数和供体胚胎的发育阶段以及受体卵母细胞的状态对NT效果有显著影响，在NT胚胎的不同发育阶段采用不同的血清种类和浓度可提高其胚胎发育能力。

Ooplasmic transfer increases the fertilizability of the aged oocytes and the early embryonic viability, it has led to the birth of health babies, and become a hotspot in the realm of human assisted reproduction biotechnology and animal clone.

卵胞质转移技术能有效改善老龄卵母细胞的受精能力和早期胚胎的发育能力，在人类已有健康后代出生，它已成为人类辅助生殖生物技术和动物克隆研究的新热点。

With the prolonging of treatment with 6-DMAP,the developmental ability of parthenogenetic embryos decreased.

随着6-DMAP处理时间加长，孤雌胚的发育能力降低。6-DMAP处理1小时的桑葚胚／囊胚的发育率(72％)远远高于6-DMAP处理6小时的桑葚胚／囊胚的发育率(28％)。

When oocytes were matured at 37-39℃,the appearance of cumulus cell had protective effect on cleavage and blastocyst rate,the development rate of DOs significantly decreased compared to COCs.

当卵母细胞在37-39℃成熟培养时，卵丘细胞对卵母细胞的发育有一定的保护作用，DOs的发育能力显著低于COCs。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
