The role of DDAH is to break down modified amino acids Asymmetric dimethylarginine (ADMA and monomethyl arginine that are produced by the body and have been shown to inhibit NO synthase.

DDAH的作用是破坏由体内产生的被修饰的氨基酸（不对称的二甲基精氨酸和一甲基精氨酸）并已证实它可以抑制NO的合成。

In the paper, the multidentate carboxylic acid ligands were used to combine with Cd, resulting in the three dimensional MOCPs single crystals—C12H16CdN2O8, with a low temperature hydrothermal synthesis method. The sample was characterized with IR spectra to affirm the organic groups in the frameworks, single-crystal X-ray diffraction to determine the crystal structure and composition of the frameworks, N2 adsorption isotherms at low temperature to measure the specific surface area and pore size distribution, and with TGA/DGA analysis to scale the thermal stability. Furthermore, the dissolution property and the photocatalytic activity of MOCPs under the ultraviolet ray condition were explored.

Dimethylnaphthalene is an ideal raw material of the production of polyethylene naphthalate. It is an important task to obtain 2,6-dimethyinaphthalene in low cost.

2，6-二甲基萘是制备高性能聚酯-聚对萘二甲酸乙二醇酯最理想的原料，如何低成本地获得2，6-二甲基萘已成为一项重要的课题。

Reactions of 2-methyl-1,4 naphthoquinone with human telomeric DNA and telomerase RNA ESR spin elimination has been used with 4-oxo-TEMPO as spin trap. The reactivities of 3VK3* with telomeric DNA, template of telomerase RNA and its L6-P6 region have been confirmed respectively. The results show that the reactivity of 3VK3* with polynucleotides is directly proportional to their G amount, and the one for reaction of 3VK3* with telomeric DNA is the highest in polynucleotides. 2. Reactions of 2-methyl-1,4 naphthoquinone with nucleosides, nucleotides ESR spin elimination has been used with 4-oxo-TEMPO as spin trap.
