精子核

Fig 1 The results of two color FISH A:Normal sperms(a sperm nucleus with a red fluorescence domain was X sperm, and with a green fluorescence domian was Y sperm);B:Numeric chromosome abnormal sperm two green fluorescence domains within the same sperm nucleus which may be classified in Y disomic sperm or diploidy sperm, in the case of hybridization with two probes, one euchromosome specific and the other sex chromosome specific, this sperm could be discriminated as disomic or diploidy sperm

图1 双色荧光原位杂交结果 A：正常精子(精子头部有1个红色荧光信号者为X精子，有1个绿色荧光信号者为Y精子)；B：染色体数目异常精子两个绿色荧光信号同在1个精子核内，可为Y双体精子或二倍体精子，若用1条常染色体探针和1条性染色体探针进行双色荧光原位杂交，可以区别该精子属Y双体精子或二倍体精子

Parthenogenesis in which the egg is activated by sperm ,but without fusion of the egg and sperm nuclei.

雌核生殖一种单性生殖，精子激活卵子，但是卵子和精子核没有融合

In the present study, several chromosomes were simultaneously marked successfully in the same sperm nucleus within 2.5 hours.

在2.5 h内标记了同一精子核内的多条染色体，单色以上标记达到99％。

Results: Within 2.5 hours, three chromosomes had been simultaneously marked in same sperm nucleus.

对每条染色体的评估都至少分析5000个精子核。

Sperm nucleus immaturity rate in each AlCl3 group increased significantly (P.01) with a dose dependent manner.

精子核荧光染色试验中，高、中、低剂量AlCl3染毒组未成熟精子率均高于阴性对照组，差异有统计学意义(P.01)；且未成熟精子率随着AlCl3染毒剂量的升高而增加。

Uu infection may reduce the sperm membrane integrity and sperm nucleus DNA maturity.

Uu感染能够降低精子膜的完整性以及精子核DNA的完整性，这可能是Uu致男性不育的又一因素。

Methods Molecular epidemiological investigation of 249 men from different groups(training and non-training)was carried out by using flow cytometer to detect the integrity and damage of in situ DNA of sperm nucleus, and sperm chromatin structure assay was performed.

应用流式细胞仪快速测量精子核原位DNA损伤和完整性，分析精子染色质结构，对两组不同作业环境(过度训练组与非训练组)的 2 4 9名男性官兵进行分子流行病学调查。

Two polar nuclei move to the micropylar end before sperm is released in a gap between the egg cell and central cell and subsequently taking off cytoplasm one after another. The sperm nucleus moving to the egg nucleus runs faster than the one to the polar nuclei. It fuses with the polar nuclei that are moving towards the antipodal cells at the chalazal end.

精子释放前，两极核移向卵细胞的合点端；两精子释放于卵细胞与中央细胞的间隙后，先后脱去细胞质，然后分别移向卵核和极核，移向卵核的精核快于移向极核的精核；精核与两极核在向反足细胞团方向移动的过程中完成雌雄核融合。

Solen grandis was longer than Solen strictus. The nuclear of Solen grandis was warhead-shaped while one of Solen strictus's was spherical. A satellite body was found in Solen grandis but not in Solen strictus. In addition, Solen grandis had a longer tail than Solen strictus.

大竹蛏的顶体比长竹蛏的稍长；大竹蛏精子核形似子弹头而长竹蛏精子核形为圆球状；大竹蛏有卫星体结构而长竹蛏无卫星体结构；大竹蛏精子尾部鞭毛比长竹蛏的长。

We estimated incidences of disomy and for 2 autosomes and 2 gonosomes in sperm samples from 2 normal fertile men.

结果成功地在2.5小时内标记了同一精子核内的多条染色体，最佳的染色体同时标记通量为3条，单色以上标记率达到99％。

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。
