查询词典 sperm

Epidemiologist Luc Smits of Maastricht University, the Netherlands, who led the study, believes the results support the idea that sperm bearing the male Y chromosome swim faster than sperm with the female X chromosome, and can travel through viscous cervical mucus more easily.

荷兰Maastricht大学的流行病学家Luc Smits领导了这项研究，他相信这项结果支持携带Y染色体的精子游的速度要快于携带X染色体的，且更容易穿过粘性子宫颈粘液的想法。

Most sperm nuclei eventually developed into the male pronuclei, just like the normal sperms, except sperm nuclei in a few zygotes kept dense throughout the fertilization process. Dense chromosome body was seen at the nuclear area during the prophase of first mitosis, and in the middle of spindle at metaphase of first mitosis.

精子入卵后形成精核，大多能够逐渐解凝、液化并膨大，最终形成形态正常的雄性原核，但在第一次卵裂早期退化成浓缩的染色质小体，并在胞质分裂时随机地分配到其中一个子细胞里的分裂沟附近。

He spins a special web, expels sperm onto it, then sucks the sperm into bulbs on the ends of his pedipalps

它会织出一个特殊的网，将精液排在上面，然后把精液吸附在须肢末端的球状物上。

He spins a special web , expels sperm onto it , then sucks the sperm into bulbs on the ends of his pedipalps .

译文蛛丝出自于蜘蛛的腺体，这些腺体构成了蜘蛛腹部的很大一部分。

Because the long chained fatty acids are better oxidised, the sperm cell will have higher energy content and thus the motility of the sperm will increase.

由于长链脂肪酸的利用率提高，精细胞将获得更高的能量，使其活力增强。

Estrogen can promote the sperm motility in fertile men. The mechanism may be explained by the ［Ca2+］i increase and activation of adenylyl cyclase caused by the integration of estrogen with the membrane receptor on human sperm.

雌激素在体外可增强正常人精子的运动力，该效应可能是通过雌激素与人精子膜上雌激素受体结合后，升高精子胞内Ca2+的浓度以及激活腺苷酸环化酶而实现的。

These studies demonstrate that the more abundant D form interacts with spermatozoa transiently, possibly with a specific receptor on the sperm surface, consistent with a capacitation-suppressing function during sperm transit and storage in the epididymis, and also confirm a tightly bound population of the E form that could act in the female reproductive tract.

研究证明在附睾中运输和储藏期间，大量的D型CRISP-1与精子瞬时的结合与精子的抑制获能功能相关。D型CRISP-1可能与精子表面的受体相结合。同时也证明了E型CRISP-1与精子的紧密地结合模式可能在雌性生殖道中发挥作用

MATERIAL AND METHODS: Thirty 30 healthy Sprague- Dawley adult male rats were randomly divided into 3 groups: control, alcohol 7.5 g/kg and alcohol 7.5 g/kg ＋ vitamin A 50 μ g/kg. Alcohol and vitamin A were administrated to the rats for 13 weeks by a gastric tube. The sperm counting ,motility and the percentage of abnormal sperm were observed. Serum testosterone was determined. The patholgical changes of testicle tissue of rats were observed by light and electron microscopy.

材料与方法： 30只健康雄性成年 SD 大鼠随机分为对照组、酒精组、酒精＋ VA 组，各组每日分别灌胃给予酒精0、7.5 g/kg 、酒精7.5 g/kg ＋ VA 50 μ g/kg ，连续13周后对各组大鼠的精子计数、精子活动率、精子畸形率、血清睾酮(Serum testosterone，T )进行检测，光、电镜观察睾丸生精上皮的组织学改变。

Sperm antibody test to check for protein molecules that may stop sperm fertilising an egg.

精子抗体测试，以检查蛋白分子可能会停止精子fertilising一个鸡蛋。

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。
