This shows a high relationship between immunity and endometriosis.Conclusion The quantity of cell factors in abdominal cavity fluid plays an essential role in the occurˉrence of endometriosis.

腹腔液中细胞因子的变化与内异症有着密切的关系，对内异症的发生起着重要的作用。

ObjectiveDuchenne and Becker muscular dystrophy is the most common human X-linked recessive inherited disease.The absence of dystrophin on the sarcolemma results in DMD,which is the essential physiopathologic mechanism.

假肥大肌营养不良是男性最常见的X-连锁隐性遗传病，而肌营养不良蛋白在DMD患者肌细胞上的表达异常是导致该病发生的最根本的病理生理机制。

ABSTRACT We divided spermatogenesis into two parts:The first part is the differentiation of spermatid and the second part is spermiogenesis.This is the second.

摘 要 华支睾吸虫精子的分化可以发现分为两部分，一是精细胞疼痛的发生，二是精子的形成，本文护士报道的为第二部分。

To screen resistant rice varieties in Liaohe Valley to the rice stem borer Chilo suppressalis Walker, development of and damage by the borer larvae on the varieties were examined using intact-plant resistance evaluation method, and morphological and biochemical characteristics and number of silica cells of the rice varieties were determined to explore the potential resistance mechanisms.

采用活体成株鉴定法测定了辽河流域主栽水稻品种对二化螟发育和为害的影响，同时测定了不同品种的主要形态特性、硅细胞数量和主要生化特性，评价这些品种对二化螟的抗性、分析其发生的可能机制。

Result:After removal of the bilateral lower molars, the remodeling and degenerative activities in different layers of the condyles increased, such as vesiculation of endoplasmic reticulum, distortion of mitochondria and increase of lysosome. Furthermore, the sequential arrangement of collagen fibrils was disturbed, the collagen network broke down and the proteoglycan granules decreased.

结果：细胞发生了不同程度的改建及退行性反应，如粗面内质网的扩张，线粒体肿胀，溶酶体增多等；基质中胶原原纤维的有序排列结构消失，胶原网受到破坏，同时蛋白多糖颗粒减少；基质中脂质小体及基质小囊等成分增多；负重区较非负重区的改变更显著。

While PcG proteins are best known for the roles in maintaining the correct expression pattern of key developmental regulators, such as Hox genes, there is accumulating evidence that they are also involved in the regulation of cell proliferation and tumorigenesis.

众所周知，PcG蛋白可以维持关键的发育调节因子如Hox基因的准确表达模式。而且，现在越来越多的证据现实，PcG蛋白也参与了对细胞增殖和肿瘤发生的调节过程。

We also found that apoptosis was induced by terfenadine in human cancer cell by DNA laddering formation. In this study,we demonstrated that p21、p27、BAX and BAD protein were induced,in contrast,Bcl-2 protein was down regulated by treated with terfenadine.

经过琼胶电泳分析Terfenadine会使人类癌细胞产生DNA ladder的特徵，表示细胞发生凋亡，并随著剂量的增加我们发现：p21、p27、Bax、Bad表现量上升，而PARP有被切断的片段产生，Bcl-2、Caspase-3减少，而且p27有被切断的情形产生。

Expression analyses identified increased expression of numerous TGF-beta-related genes that regulate cell proliferation and survival and plausibly contribute to myxomatous valve disease.

他们注意到，多数效应器分子的表达增加降低了TGF-β的信号作用，包括可诱导TGF-β的H3基因、内皮素-1、组织抑制因子金属蛋白酶1、致骨形态学发生的蛋白和&调节细胞增生和存活可能还有促进粘液瘤性疾病的基因&。

Somatic embryogenesis is a remarkable illustration of plant totipotency,and under appropriate culture medium can develop to an adult plant with high frequency, so it is a excellent system for genetic improvement.

植物体细胞胚发生是植物细胞全能性的重要体现，在适宜的培养条件下能够以较高的频率再生出完整的植株，是植物遗传改良受体系统。

Here we report the crystal structure of the parainfluenza virus 5 F protein in its prefusion conformation, stabilized by the addition of a carboxy-terminal trimerization domain.

首先，它们以一个亚稳态的形状出现，这个形状能储存进入细胞所需的能量；然后，该蛋白形状所发生的不可逆转的变化促成膜的融合。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
