In addition of cytomorphologic identification, immunolhistochemic technique of bone morphogenic protein-monoclonal antibody, alkaline Phosphatase staining and concentration assays, as well as osteoblasts reaction to PTH-cAMP were used, according to the biologic character of osteoblasts.

除了在细胞形态学上对其鉴定外，还根据成骨细胞的生物学特性，首次引用了骨形成蛋白单克隆抗体免疫细胞化学技术，以及碱性磷酸酶染色和含量测定，成骨细胞对甲状旁腺激素-cAMP反应等方法，验证了经酶消化分离培养的兔颅骨细胞具有成骨细胞的功能和特性。

TGF-β s are multifunctional cytokines with a broad range of biological activities. TGF-β s belong to a family of related proteins, which demonstrate various degrees of amino acid sequence homology; this protein family is called the TGF-β superfamily. Other members of this family include the bone morphogenetic proteins, inhibin, activin and Mullerian substance.

TGF-β类生长因子是一类具有广泛生物学活性和重要临床应用价值的细胞因子，包括多种蛋白因子，它们在氨基酸结构上具有不同程度的同源性，共同构成了TGF-β超家族，包括BMPs、活化素、抑制素和缪勒氏物质等。

On the other hand, Biblical chronology, as then understood, and the literal historic interpretation of the Book of Genesis were thrown into confusion by the advancing sciences -- astronomy, with its grand nebular hypothesis; biology, with its even more fruitful theory of evolution; geology, and prehistoric arch ology.

另一方面，关于圣经年表，然后相互理解，字面上的历史诠释这本书的成因被扔进混乱所推进科学-天文学，其宏伟n ebular假说；生物学，其取得更加丰硕的成果进化论；地质学和史前拱学。

AIM:To investigate the expression of Nestin in human neuroepithelial tumors and to evaluate the biological characteristics of Nestin positive tumor stem cells in vitro and the significance.

目的：检测巢蛋白在神经上皮肿瘤组织、细胞中的表达，评价Nestin+细胞体外生物学特性并探讨其意义。

The detection of Nestin expression contributes to correctly evaluate the malignant degree and biological behaviors and is an important clue to ascertain the pathological grades and prognosis of neuroepithelial tumors.

Nestin表达检测有助于正确评价神经上皮肿瘤的生物学行为和恶性程度，并可作为判断肿瘤病理级别和患者预后的重要依据。

There are postulations that some positions of GP is the structural basis for some important biologic features of rabies virus, neurotropic, pathogenicity and antigenicity.

狂犬病毒GP基因上某些位点推测是狂犬病毒一些重要生物学特性，如：组织嗜性、致病性和免疫原性等的结构基础，因此这些部位的变异有可能导致这些特性的改变。

Impacts of transgenic rice lines on biological characteristics of Microvrlia horvathi Nymphal duration of Microvrlia horvathi fed with young instar of BPH nymphs feeding on Bt rice after hatching was not significantly different from that feeding on Xiushui 11 control.

七、转基因抗虫水稻对尖钩宽黾蝽生物学特性的影响饲喂转基因水稻或对照品种上饲养的褐飞虱，两种转基因水稻处理组的尖钩宽黾蝽各龄若虫历期和整个若虫期与它们各自的对照都无明显差异。

Rice (Oryza sativa L.) is not only one of the most important food crops in the world,but also a model plant for study of molecular developmental biology in monocots.

水稻是世界上最重要的粮食作为之一，也是单子叶植物发育生物学研究较理想的模式植物。

"Microbes that produced methane from hydrogen and carbon dioxide were one of the earliest forms of life on Earth," notes Carl Pilcher, Director of the NASA Astrobiology Institute which partially supported the research.

&微生物产生的甲烷，氢气和二氧化碳是最早形式的地球上的生命，&注意到卡尔尔彻主任美国宇航局天体生物学研究所的研究部分支持。

In this text, comparing the yak with other genus of Bovinae on paleontology evidence, morphologic character, blood protein polymorphism, microsatellite polymorphism, mtDNA sequence variance, rDNA RFLP data and sequence information of function gene, we find that the yak shows difference in Bos taurus, Bos indicus but close with Bison bison either in paleontology evidence, morphologic character or molecular biology character. So it was better to be considered as one independent genus Poephagus than to subgenus Poephagus or a species of Bos.

本文通过对牦牛与牛亚科其他属在古生物学证据、形态学特征、血液蛋白多态性、微卫星多态性、mtDNA序列变异、rDNA的RFLP数据和功能基因序列信息等各方面研究资料的比较分析，发现牦牛无论在古生物学证据、形态学特征，还是在分子生物学特征上均表现出与牛属中的普通牛Bos taurus、瘤牛Bos indicus不同，而与美洲野牛Bison bison的亲缘关系更近一些，因此将牦牛划分为牛亚科中1个独立属，似乎比将牦牛作为牛属中的1个亚属或1个种更合适。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
