This motion causes fluid to flow across the surface of an epithelium or a sperm cell to swim through the medium. 有些细胞有质膜的一个长,苗条引伸,叫纤毛或鞭毛,摔打以whiplike方式。 这行动造成流体横跨皮膜的表面或精子细胞流动对游泳通过媒介。 [translate] ...
Molecular docking is a computational technique that predicts the binding affinity of ligands to receptor proteins. Although it has potential uses in nutraceutical research, it has developed into a formidable tool for drug development. Bioactive substance

When processing current sensory inputs, animals refer to related past experiences. Current information is then incorporated into the related neural network to update previously stored memories. However, the neuronal mechanism underlying the impact of mem
On the micron- and nanoscale, the invention of optical tweezers6,7 enables to exert well-controlled forces on viruses, living cells, and synthetic colloids to probe, for example, the viscoelastic properties of DNA and cell membranes, or to measure forces exerted by molecular motors7,8. An ...
To test the intactness of sperm long RNAs, we also need precise annotation of the transcriptome in testis and sperm. However, the reference transcriptome (RefSeq) annotation is incomplete and unprecise. Testes, where germ cells (precursors of sperm) constitute ~90% of the cell population27,28...
