顶膜

The apical membrane of the epithelial cells is apparently essential.

上皮细胞的顶膜显然是必要的。

Scanning electron microscopy and confocal microscopy were used to observe and quantify the apical surface of HRCs.

利用扫瞄式电子显微镜和共轭焦显微镜来观察和量化HRCs的顶膜开口型态和密度。

The apical surface area and density of HRCs were higher in pH 4 than in pH 7 acclimated larvae.

仔鱼驯养在pH 4环境中，HRCs的顶膜开口面积和密度显著大於驯养在pH 7环境下的仔鱼。

During capacitation Ca〓 was present on the outer surface of IAM and in the released acrosomal contents.

精子获能前内存Ca〓主要分布于顶体外膜内侧和顶体内膜与核膜之间，并在获能和顶体反应过程被动员利用；顶体反应精子Ca〓分散存在于释放的顶体内容物中和结合于顶体内膜外侧，可能与顶体酶的活性有关；（9）。

Pylori infection can result in hypochlorhydria,the molecular mechanisms underlying this phenomenon remain poorly understood.Most of formerly study focused on the immunoregulatory cells.

以往的研究多集中在免疫调节细胞，我们的研究结果表明，VacA毒素能够直接诱导胃壁细胞顶膜通透性的增加，导致胃酸分泌的减少。

Immunofluorescence analysis showed that AQP1 was expressed in the apical and basolateral membranes of epithelial cells in proximal tubules, as well as in the thin descending limb of Henle and endothelial cells of descending vasa recta.

免疫荧光定位分析结果表明AQP1 在近曲小管上皮细胞顶膜和基底膜表达，也表达于髓袢降支细段和直小血管降支，肾囊泡上皮细胞未见AQP1表达。

Above the tiers 层 of plastic seats and confident-lookingclocks, the roof is a simple membrane 膜,隔膜 designed to keep out sun and storm (theOlympics take place in August, when Beijing is hot and thundery) and to act asa foil 烘托 to that intricate 复杂的,错综的 steel skeleton.

在一排排的塑料座位和许多外观大气的时钟上方是一个单层膜结构的穹顶，这个膜结构既可以阻挡烈日和暴风雨（奥运会于8月举行，正值北京炎热和雷雨较多的季节），同时也可以给复杂的钢结构提供衬托。

In order to understand better the process of hydrocarbon formation and the effect of the top land crevice and the oil layer of the cylinder liner on unburned hydrocarbons during cold start and idling period,the temperature of piston top land and liner has been measured.

为了更好地弄清起动和怠速时发动机缸内未燃碳氢生成过程以及顶岸间隙和油膜对缸内未燃碳氢的影响，测量了起动和怠速过程活塞顶岸壁面和缸套壁面温度。根据测量结果，预测了起动过程顶岸间隙和壁面油膜处未燃碳氢生成量，发现顶岸和缸套壁温在发动机起动后（150～200）s时达到其稳定状态。

Over-expressing GAP-deficient ACAP4 results in an inhibition of apical membrane-cytoskeletal remodeling and parietal cell secretion.

过量表达GAP活性缺陷型的ACAP4突变体抑制了顶膜-骨架的重构和壁细胞酸的分泌。

A shift from proselytising condom use to proselytising abstinence before marriage and fidelity within it.

此事的原因尽在多数人的想法转变－对使用避孕套的顶膜崇拜转向了对婚前节欲的崇拜，而且是打心眼这么想的。

Do you know, i need you to come back
