The properties of Mucor protease are studied. The Mucor protease are multienzymes that contain neutral and alkaline protease that have optimum pH in 9. 4 and a stable pH range 5. 5~10.The optimum temperature for neutral is in 60 ℃ and alkaline in 50℃. The activity of enzymes is stable for 100min in 40℃ and 50℃ incubation.

二、检测了毛霉蛋白酶的性质,结果表明毛霉蛋白酶系以中性及碱性蛋白酶为主,该酶系的最适pH为9.4,在PH5.5~10的范围内稳定,中性蛋白酶的最适温度为60℃,碱性蛋白酶的最适温度为50℃,在40℃、50℃保温100min酶活稳定,属于中高温型蛋白酶。

He number of TCR V(Vα equal s to 100 and Bβ equals to 30 ) is less than the one of lg Vh (Vh equals to 300),for TCR V is subject to negative selection of major histocompatibility complex according to the neutral theory We discussed that is somatic mutation or DNA rea rrangement the main force in producing antibody diversity and are there pseudoge nes in TCR V or not.

CR V的数目(V α为100,Vβ为30)远少于Ig VH(数目为300),原因是前者受到主要组织相容性复合体的制约,即受到负选择,这与中性学说观点相一致。文章还讨论了体细胞突变和DNA重排对两类抗体多样性产生上的作用,并探讨了Ig VH和TCR V的假基因问题。关键词分子进化,协同进化,免疫球蛋白,T细胞受体,中性学说

Nowadays, in the field of education, technology neutralism is a generally accepted theory of technology value, and "Technology is a two-edged sword" is a classical description of it. But it is a pity that the theoretical base of neutralism has been widely opposed in the field of philosophy, so it isn't dependable at all.

当前,在教育领域,技术中性论是人们广为接受的技术价值理论,"技术是一把双刃剑"是其观点的经典表述,但遗憾的是,中性论的理论基础已经遭到了来自哲学界的广泛质疑,其观点根本靠不住。

There is obvious vertical wind shear in the former, since in the low layer its cyclonic convergence is caused by three currents from southwest, southeast and north respectively, while in the upper layer its divergence is mainly due to strong northeasterly current.

随着对流的发展,垂直运动的最大值区所在的位置向上伸展,饱和层与中性层也不断向上扩展,对流层中层的中性层结既是对流发展的结果,又可能是其维持机制之一;d。

It has been observed that pyrocatechol and m-phenylenediamin can sensitively inhibit the discoloration of neutral red oxidation by the H2O2 and in the presence of catalyzer Fe in dilute sulfuric acid solution but the inhibitory effects of two organic compounds can not be added. Based on this research, the advantages of artificial neural network were adopted to handle the experimental data and a new inhibitory kinetic spectrophotometry of simultaneous determination for pyrocatechol and m-phenylenediamin with artificial neural networks was established.

在硫酸性介质中,Fe能够催化H2O2氧化中性红褪色反应,邻苯二酚和间苯二胺都能阻抑该催化氧化褪色反应的速度,研究发现:两者对Fe催化H2O2氧化中性红褪色反应阻抑作用不具有加和性,根据这一现象,用人工神经网络处理非线性体系的优势进行数据处理,从而建立了一种新的测定邻苯二酚和间苯二胺混合物的人工神经网络阻抑动力学光度法。

Mechanistically, expression of a molecule known as P-selectin by the platelets was crucial for mediating the platelet-neutrophil interaction, which induced platelets to produce proinflammatory factors such as TXA2. The authors therefore suggest that disrupting the platelet-neutrophil interaction or blocking the proinflammatory factors produced as a result of this interaction might provide new therapeutic targets for the treatment of individuals with ALI.
