查询词典 diatomic molecule

Objective To study the mechanisms and treatment of ischemia /reperfusion injury, expression of intracellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule 1 (VCAM-1) were measured, the effect on suppression of ICAM-1 and VCAM-1 by the pyrrolidine dithiocarbamate were investigated.

目的 为研究心肌缺血-再灌注损伤的机制和治疗途径，检测血管内皮细胞缺氧/再给氧后细胞间黏附分子- 1(intracellular adhesion molecule1，ICAM- 1)和血管细胞黏附分子- 1(vascular cell adhesion molecule1，VCAM-1)的表达，探讨抗氧化剂吡咯烷二硫氨基甲酸酯(pyrrolidine dithiocarbamate，PDTC)对血管内皮细胞表面细胞黏附分子表达的抑制作用。

The molecular compositions of PCE-CGH and PCE-CGL were investigated by chromatography and chemical analysis. Rhamnose, arabinose, glucose and galactose were proved to be the main strctural unit of PCE-CGH, and trifle glucoronic acid was identified in the molecule. The compositions of PCE-CGL were relatively complicated. Inositol and amino sugars besides for glucose and galactose were also identified in its molecule.

其中，PCE-CGH主要是以鼠李糖、阿拉伯糖、葡萄糖和半乳糖为结构单元的大分子多糖类物质，并含有少量的己糖醛酸；PCE-CGL的分子组成相对复杂，除含有葡萄糖和半乳糖外，还含有一定量的肌醇和氨基糖。

Its absorption by a molecule causes all sorts of subtle changes in the vibrational or rotational energy of the molecule.

一个分子能吸收红外光引起分子中振动能量和旋转能量的各种各样的微小变化。

Based on our recent discovery on single molecule detection, scilicet molecular counts decrease with the increase of molecular weight, we also studied heparin-G-CSF interaction at single molecule level.

实现了调亡细胞活性氧类和谷胱甘肽的同时检测，以及细胞样品RNA的完整性评价，并取得了单细胞裂解和内涵物测定的初步结果。

This model of semiconservative replication-conservative because each new molecule has one half of the former parent molecule-was later confirmed by the work of Meselson and Stahl.

这个DNA复制模型称为"半保留复制"，因为两个新的DNA双螺旋分子中各含有一条母链。此模型之后得到了梅塞尔森和斯塔尔的证实。

There are two independent molecules of ZnL or Co(IIL and two water moleculesin one asymmetric unit of complex 1(or 2), the crystal structure of CuClL_1·2H_2O consistsof one molecule of CuClL_1 and two water solvate molecules in the asymmetric unit,while the ZnL·CH3OH (4) comprises of one molecule of ZnL and a methanolmolecule in per unit.

在这四个金属配合物中，配合物(1)和配合物(2)的每个不对称单元中有两个独立的MLZn(IIL、CoL分子和两个水分子，配合物(3)的每个不对称单元中有一个CuClL_1分子和两个水分子，而配合物(4)的每个不对称单元中只有一个ZnL分子和一个甲醇分子。

Supported input file formats include Brookhaven Protein Databank, Tripos Associates' Alchemy and Sybyl Mol2 formats, Molecular Design Limited's Mol file format, Minnesota Supercomputer Centre's XYZ format and CHARMm format files. Different parts of the molecule may be represented and coloured independently of the rest of the molecule or displayed in several representations simultaneously.

支持的输出文件格式包括pdb，mdl，msc，xmol，CHARMm 分子的不同部分可以在颜色和代号上相互区别，也可以以不同的表示方式同时呈现。

Surprised, the researchers then examined the trypanosome genome more carefully and discovered enzymes that in other organisms are known to increase the size of a fatty acid molecule - dubbed elongases, for making fatty acids longer - but never have been shown to actually make a new fatty acid molecule.

奇怪的是，这是研究人员更仔细地检查了锥虫的基因组，发现在其他物种中作为抑止能增加脂肪酸长度的分子（同步复制延伸酶，目的是合成更长的脂肪酸，但是从来没有发现它真正能合成脂肪酸分子）。

A two-component carbon tetrachloride system and a two-component aqueous system have been treated with the proposed strategy where only 21 calibration samples are needed, and the result showed that the predictive ability was not obviously impaired for the former system while being clearly strengthened for the latter one in comparison with a conventional way that required a calibration set of 100 samples.5 An unlooked-for experimental observation that in near-infrared spectroscopy the second overtone of aniline adsorbed by 13X molecular sieve nearly disappeared led us investigate a fundamental problem: the behavior of NIR when the outside space surrounding a molecule is too small to allow the molecule to vibrate freely.

同时，最小相关样本设计能进一步减少所需的校正样本数，且能提供更多合适变量以建立多元校正模型。这两方面的改进使模型的预测能力得以提高，其预测精度即使在水体系中也有明显的改善。五、近红外漫反射光谱在线非接触监测气-固吸附过程中出现了一个意外现象，即在近红外光谱上，被13X分子筛吸附的苯胺的二级倍频几乎完全消失了。这促使笔者深入探讨了近红外光谱的空间效应(当一分子被一足够小的刚性空间限制时，其振动的受限导致一级倍频和二级倍频强度均减少，并且后者减少的程度比前者更大)。

RESULTS The SOD activity had linear correlation with pH in the range of pH 2.2-8.0 when SOD concentration was fixed. The varication of activity after ultrosonication had linear correlcation with fluoresent intensity at 340 nm. With increase of uhtrosonic frequency, the microenviroment of tyrosine and tryptophan inside the SOD molecule was changed, then the balance of hydrophokicity and hydrophilicity inside the molecule was broken, this induced the blue shift of synchronous spectrum band and decrease of SOD activity.

结果 SOD浓度一定、pH2.2~8.0时，活性与其线性相关，超声后活性差值与340 nm荧光强度差值的线性相关；随着超声次数的增加，蛋白质SOD分子内部的酪氨酸、色氨酸所处的微环境被扰动，打破了分子内部的疏水和亲水平衡，使蛋白质的活性降低，在荧光检测中观察到普通荧光谱带蓝移，同步荧光的荧光峰位总体呈现峰位蓝移和强度下降。

Given the language of section 102(2), the Supreme Court's rejection of substantive review under NEPA seems unjustifiable in principle

按照第102条的规定，最高法院否决《国家环境政策法》所规定的实质性复审在原则上似乎是不正当的。
