查询词典 spermatozoa

The result of different thawing temperatures indicated that the spermatozoa thawn in 38℃ water showed a better survival rate than those thawn in 50℃ water; the duration of preservation on above 30% survival rate were 4 and 1h, respectively.

结果显示：3%甘油冷冻解冻后精液的活率、活力(38.54%、52.24%)显著(P.05)高于2%甘油组(15.63%、28.22%)，但3%甘油组顶体完整率(11.55%)显著(P.05)低于2%甘油组(21.71%)。38℃水浴解冻后的精子在39℃培养箱中4h内活率高于0.3，而50℃水浴解冻后1h后的活率低于0.3。

Furthermore, urogenital inflammation could also disturb the expression of TNF-α in human spermatozoa.

生殖道炎症也可能影响精子TNF-α表达，其机制和意义有待进一步研究证实。

The activation and motility of spermatozoa from Chinook salmon collected by dissection were studied under different reactivators,ASP,pH and temperature.

采集成熟的大鳞大马哈鱼精子，在不同的激活介质、人工精浆、pH和温度条件下进行活力观察。

These results indicate that the spermatozoa agglutinating activity of carp ovum cystatin decreases with increasing salt concentration and pH, which is in good agreement with the previous experimental results.

由以上结果可知，当盐浓度和pH值上升，鲤鱼卵cystatin蛋白聚精的能力会明显下降，这与先前的实验结果相当吻合。

Our homology model also shows that several positively charged residues are located on the surface of carp ovum cystatin, leading to agglutinating spermatozoa via electrostatic interaction.

由我们所建构的鲤鱼卵cystatin蛋白模型来做表面的带电性分析，可发现蛋白中带正电的胺基酸都暴露在其表面。

Of the eons of geological periods recorded in the stratifications of the earth: of the myriad minute entomological organic existences concealed in cavities of the earth, beneath removable stones, in hives and mounds, of microbes, germs, bacteria, bacilli, spermatozoa: of the incalculable trillions of billions of millions of imperceptible molecules contained by cohesion of molecular affinity in a single pinhead: of the universe of human serum constellated with red and white bodies, themselves universes of void space constellated with other bodies, each, in continuity, its universe of divisible component bodies of which each was again divisible in divisions of redivisible component bodies, dividends and divisors ever diminishing without actual division till, if the progress were carried far enough, nought nowhere was never reached.

349在地球的层理留下记录的太古以来的地质时代。隐藏在大地的洞穴里和能移动的石头底下、蜂巢和土墩子中那无数微小的昆虫类的有机生物：微生物、病菌、细菌、杆菌、精子；凭着分子的亲和之凝聚力而粘在一根针尖上那几万几亿几兆个多不胜数、肉眼看不到的微小颗粒；人类的血浆是一个宇宙，群集着白血球和红血球，每个血球又各自形成一个空虚的宇宙空间，群集着其他球体；各个球体连续性地也是由可分割的构成体形成的宇宙，各个构成体又可以分割成为几个能够进一步分割的构成体。就这样，分子与分母实际上在并未分割的情况下就不断地减少了。如果这个过程延续到一定时候，就永远在任何地方也不会达到零。

Up to now, scientists have estimated that about 3500~5000 mRNAs were retained in human ejaculated spermatozoa, and indicated that they may play important roles in the process of chromosome recombination, gene imprinting and spermatogenesis.

越来越多的研究发现成熟精子中存在有大量而复杂的mRNA群体，到目前为止，科学家们估计人正常射出的精子当中有3500-5000多种RNA，并且认为它们可能在染色体重新组装、基因印迹及精子发生过程中起着重要的作用。

In this work, by reconstituting the channel protein into lipid bilayer, Ca2+ channels in human spermatozoa were investigated with voltage clamp technique.

本工作将通道蛋白重组于脂双层，在电压箝位下记录了人精子膜的Ca2+通道电流。

In conclusion, epididymosomes are small membranous vesicles secreted in an apocrine manner in the intraluminal compartment of the epididymis and play a major role in the acquisition of new proteins by the maturing spermatozoa.

总之，epididymosomes是一种小的膜状小泡，以顶分泌的分泌方式存在于附睾管腔中，在精子成熟过程中获取新蛋白发挥着主要作用。

Progesterone and #gamma#-aminobutyric acid could initiate the acrosome reaction in guinea pig spermatozoa,which was independent of extracellular Cl一in vdro,and a potentiation effect between progesterone and GABA was demonstrated.

在体外，孕酮和#gamma#-氨基丁酸可明显地引起豚鼠精子顶体反应，并且两者合并使用，对顶体反应的诱发有协同作用；这种反应不依赖于细胞外C1-。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
