查询词典 diatomic molecule

At least 0.1μg/ml of endotoxin can induce the morphologic changes and the decrease of F-actin in HUVECs. Endotoxin can injury HUVECs only when its concentration reaches 0.4μg/ml and incubates over 12 hours. It suggests there is a different molecule mechanism in VEC from the endotoxin-CD14 pathway in CD14 positive cells.

内毒素直接损伤血管内皮细胞须较大浓度(＞0.4μg/ml)，但在较低浓度下(0.1μg/ml)可直接引起内皮细胞的一些形态学变化和F-actin含量的变化，初步推测血管内皮细胞可能存在着与通常认识的内毒素—内毒素结合蛋白—CD14途径激活细胞不同的分子机制。

For a small molecule, what part intercalates into DNA strand is of vital importance because the investigation of interaction of DNA with other molecules is of great importance in elucidating the structure of DNA and their functions.

在第一章中，首先介绍了DNA的结构，然后重点介绍了金属配合物与DNA的作用机制，并总结了目前较为常用的抗癌药物与DNA相互作用的研究方法，最后，对本论文研究的目的和意义进行了说明。

The results shown that both [Cu_2]~2+ and NR molecular can intercalates into the DNA double helix layer, and there is a competition between these two interactions. Furthermore, chemometrics approach, parallel factor analysis, was used to resolve the measured three-way CW-SFS data, which provided simultaneously the concentration information for the three reaction components, NR, [Cu_2]~2+ and NR-DNA, for the system at each equilibrium point. This PARAFAC analysis indicated that the intercalation of the [Cu_2]~2+ molecule into the DNA proceeds by exchanging with the NR probe, and can be attributed to two parallel reactions.

本工作以同步荧光技术采集了竞争作用的三维数据，并结合了化学计量学中的平行因子法对此三维数据进行分解，得到了各组分的荧光光谱图及各个反应平衡点各组分的相对浓度，平衡浓度的变化趋势也表明了铜络合物与中性红之间的竞争作用，进一步表明了铜络物与DNA的作用方式和中性红与DNA作用方式一样均为嵌插作用。

This kind of general structural intercalation complex materials have three obvious characteristics: i Conditions of intercalation reaction are wild in room temperature, water or ethanol solution usually, ii we can process molecule design of host for increasing selectivity to guest molecules in order to prepare general structural intercalation complex materials, iii we can obtain all kinds of applied purpose complex materials by intercalating different functional guests.
