Though the Waddington and von Bertalanffy programs have not been confirmed in the typical accomplishments and representations in molecular biology in general, and molecular genetics in particular, there are interesting advances that fall between those searches for broad theories couched in mathematically precise differential equation form, and the narrow classes of mechanisms, usually described in qualitative multilevel causal language, that constitute the vast majority of current biomedical explainers.

Waddington 和 von Bertalanffy氏方法，尽管其贡献和代表性并没有在一般意义上得到分子生物学或者在特别意义上得到分子遗传学的确认，但还是在以下方面产生了有益的进展，即，它使我们的广泛的理论搜寻进步到精确的数学微分方程式的形式和通常以定性的多级因果语言来描述的机理的狭窄类别之间，由此构建了当代生物医学因果辨析的主体内容。

The negative correlation was observed between S100A4 expression and Ecad expression (r=-0.385, P.05) CONCLUSION: The correlated expression of S100A4 and Ecad is closely related to the development of epithelial ovarian carcinoma,which is valuable markers in predicting biological behavior and trend of metastasis in epithelial ovarian carcinoma.

S100A4和Ecad的相关表达与上皮性卵巢癌的发生发展关系密切，是判断上皮性卵巢癌生物学行为、预测侵袭转移的重要指标。

The author reviewed the research progress on the study of several Gibberella species of agricultural importance, which represent phylogenetic, biological and chemical diversity of this genus.

选取几种在农业生产上重要的赤霉属真菌来阐述该属在系统发生，生物学和化学上的多样性，并且比较了它们在分类学、遗传学、植物病理学和真菌毒理学方面的差异。

PURPOSE: To study the different biological characteristics of human junctional epithelium and gingival epithelium.

目的：比较人结合上皮（junctional epithelium，JE）与牙龈上皮（gingival epithelium，GE）的生物学特性。

Ancient biomolecules obtained and characterized from in situ Quaternary fossils or sedimentary matrix have provided Quaternary scientists with quantitative and high resolution data that contain rich and some times unique paleobiological, paleogenetic, and paleoenvironmental information.

作者预见对第四纪地层中的原位和分散保存的古代生物分子的研究将在广度上以多分子综合研究而深度上与单体分子同位素技术相结合，为第四纪科学家们提供大量解决地质学和演化生物学问题的高精度数据。

Expression of CD44V6 can be an early biological indicator of precarcinomatous epithelial cells. Gastric mucosa intestinal metaplasia can induce the expression of CD44V6, moreover, Hp infection can promote it.

CD44V6的表达可能是上皮细胞癌前病变出现的早期生物学信号，肠上皮化生细胞可能诱导CD44V6的表达，而Hp感染则有促进这种诱导表达的作用。

However, my recent interviews with children living in the group of islands that includes Tertia show that these children spend much more time talking about their biological parents than about other adults in the village.

但是，我最近对生活在包括Tertia岛在内的该群岛上的孩子所作的访谈表明，这些孩子更多时间谈论的是其生物学意义上的父母而不是村子里的其他成人。

The amount of Ni and Cr released from specimens coated with gold was much fewer than those from unplated specimens (P .05), which meant the stability of Ni-Cr alloy on the surface was improved. The biocompatibilities of gold-coated Ni-Cr alloy were better than the uncoated alloy, though there was no difference in biological ranking.

说明其耐电化学腐蚀能力明显提高；镀金后镍铬合金试件的镍离子、铬离子析出量降低，表面稳定性有了显著性提高；无氰镀金法镀金的镍铬合金生物相容性良好，从数据上比较优于未镀金镍铬合金，但生物学评级上无显著性差异。

The histone octamer may protect the wrapped DNA from interacting with other environmental factors such as transcription regulating proteins, thus the positioning of nucleosomes along DNA may play important roles in multiple cellular processes including DNA replication, transcription and damage-repair.

由于核小体结构中的DNA缠绕在组蛋白八聚体上，可能影响这些DNA与细胞内的其他蛋白相互作用，从而影响到DNA复制、转录等生物学过程，因此，核小体在基因组上的位置分布可能对基因组功能具有重要的调控作用。

Complete genome sequences of 20 viruses in Bunyaviridae loaded from NCBI were analyzed by two biological softwares of DNAMAN and DNASTAR. The results indicated great variability in both nucleic acid sequence and protein structure between plant viruses and animal viruses:(1) only plant viruses could encored NSm in M genome;(2) the length of nucleic acid sequence and protein sequence was different;(3) GC content of nucleic acid of animal viruses was higher than plant viruses of that;(4) protein topology analysis by online software SMART discovered that there was significant difference for the structure of glycoproteins G(subscript nG between animal-infecting and plant-infecting viruses;(5) usually, protein of plant-infecting virus had more complicated structure, more low compositional complexity and had N-Signal peptides except INSV.

本文从NCBI数据库下载具有完整基因组序列的布尼亚科病毒的5个属20种病毒的序列，用生物学软件DNAman，DNAstar进行比对分析，发现布尼亚科病毒属中的植物病毒在核酸序列及蛋白结构上与动物病毒有很大差异：(1)只有植物病毒的M基因组能编码NSm运动蛋白；(2)植物病毒和动物病毒在核酸序列和蛋白质序列长度均有差异，表明该科病毒是进化速度较快的病毒；(3)植物病毒核酸序列的GC含量低于动物病毒；(4)通过SMART网络软件进行蛋白质拓扑结构分析发现植物病毒和动物病毒在糖蛋白GG的结构上存在显著差异；(5)植物病毒糖蛋白结构较为复杂，有较多的紊乱区域，除INSV外，其他病毒都具有N端信号肽。

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.
