Loss of the integrity of basement membrane often relate to the occurrence, infiltration and metastasis of tumor.

基底膜完整性的破坏常与口腔鳞癌的发生、浸润及转移有关，而基质金属蛋白酶家族蛋白在此过程中发挥了重要的生物学作用。

Objective To explore the relationship between the protein expression of PCNA and biological behavior science in benignant pituita ry adenoma.

目的 探讨良性垂体腺瘤中增殖细胞核抗原蛋白表达与肿瘤发生及生物学行为的关系。

Chloroplast biogenesis is a fascinating area of plant biology. The development of these photosynthetic apparatus is studied at the level of structure, biochemistry, genetic, and molecular biology.

叶绿体的生物发生是植物生物学中一个重要的研究领域，这些光合器官的发育主要从结构、生化、遗传和分子水平上进行研究。

Inclusion criteria: 1 research of the structure and bionomics of DKK-1; 2 the relationship between DKK-1 and myeloma.

纳入标准：lDKK-1基因结构及生物学特征的研究；2DKK-1与骨髓瘤发生关系研究。

The bionomics of Dendrolimus kikuchii was investigated. The reasons of outbreaks were discussed and the control measures of the pest were proposed in the paper.

摘要调查了思茅松毛虫的生物学特性，并对大发生原因进行了分析和探讨，同时提出了对该虫的防治措施。

In this articl, the background, the thoretical source and the basic content of Cuvis catastrophism are discussed, It is shown that it is not a subjective fabrication by Cuvier, but rather it is inherited from reforming former catastrophic ideas, on the basis of his long-term scientific practic, Therefore it helped to push forward the dvelopment of gology and biology.

本文论述了居维叶灾变论的产生背景，理论来源及其基本内容，证明它并不是居维叶的主观臆造，而是他在长期科学实践基础上对前人灾变思想的继承和改造。因此它对地质学和生物学的发展曾起到巨大推动作用。本文还论述了居维叶灾变论与其它灾变学说的区别；并列举大量现代科学发现证明居维叶所谓的灾变是不可否认的事实，是自然界中具有确定原因的必然发生的历史事件。

The detailed pathological lesions and the dynamic location of AEV in natural and experimental cases of chicken, chickling and embryos were reported. And AEV agar gel precipitin antigen and an inactivated oil-emulsion vaccine against AE were produced.

本项实验研究，旨在过去工作的基础上，利用分子生物学、分子免疫学的技术手段，探讨和揭示AE发生发展过程中的某些分子发病学机理的问题，并试图建立一种具有普遍指导意义的动物分子病理学研究的工作模型。

By measuring changes of Plasma levels of GMP-140, GP lib/III a and D-dimer in patients with OSAS before and after the institution of nasal continuous positive airway pressure, we want to study whether plate activation and enhance coagulability, fibrinolytic activation occur and play a role in prevalence ofcerebrovascular and cardiovascular events in patients with OSAS and the association with hypoxemia, if so, whether therapy with nCPAP alters this effect.

我们通过检测OSAS患者血浆α-颗粒膜蛋白(GMP-140)、血小板膜糖蛋白Ⅱb／Ⅲa和D-二聚体的变化，了解OSAS患者体内是否也存在血小板活化、凝血激活和继发纤溶亢进及其与低氧血症的关系，进一步从分子生物学角度探讨血小板活化、凝血激活和继发纤溶亢进在OSAS发生发展中的作用及经鼻持续气道正压通气对其影响。

The epilepsy model induced by kainic acid is a dynamical model condition. 5-7 days after acute seizure episodes induced by a single systemic injection of a convulsant dose (10mg/kg) of KA the rats developed a long-lasting increase in seizure susceptibility and the characteristic histopathological features in the hippocampus similar to human TLE. So the KA model has been a well-known model to study TLE or intractable epilepsy.

颞叶癫癎红藻氨酸（kainic acid，KA）模型具有明确的动态变化过程，一次全身性给予惊厥剂量（10mg/kg）KA诱发SD大鼠急性癫癎发作后5-7天，动物开始出现癫癎发作敏感性长期增强，脑内亦发生与人类颞叶癫癎相似的神经病理、神经生化及神经分子生物学方面的改变，因此被认为是研究颞叶癫癎和难治性癫癎的理想模型之一。

"What is happening in biology is similar to trends seen in recent decades in the physical sciences," Cummings said.

"生物学发生的近似自然科学领域近十年所看到的趋势，" Cummings说。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
