| 1 | Molecular basis for the selective and ABA-independent inhibition of PP2CA by PYL13显示文摘PYR1/PYL/RCAR 家庭蛋白质(PYL ) 是描绘得好的 abscisic 酸(骆驼毛的织物) 受体。在在 Arabidopsis thaliana 的 14 个 PYL 成员之中, PYL13 是无反应的骆驼毛的织物,它的功能留下了逃犯。这里,我们证明 PYL13 有选择地禁止独立于骆驼毛的织物的 PP2CA 的磷酸酶活动。PYL13-PP2CA 建筑群的水晶结构,它在 2.4 Å 坚定;分辨率,阐明在 PP2CA 和 PYL13 之间的特定的识别的分子的基础。除了在 PYL 和 PP2Cs 之间的正规相互作用,一个额外的接口被识别在附近包含一个元素一以前在 PP2CA 的 uncharacterized CCCH 锌手指(ZF ) 主题。顺序强风识别了另一 56 包含 ZF PP2Cs,所有哪个从植物。结构也为 PYL13 的 ABA 无反应揭示分子的决定因素。最后,生物化学的分析建议那 PYL13 可以有 PYL10 的 hetero-oligomerize。这二 PYL 在他们 PP2Cs 的各自的骆驼毛的织物无关的抑制反对对方。生物化学、结构的研究在植物的压力反应提供重要卓见进 PYL13 的函数并且为 PYL13 的未来 biotechnological 应用程序安装一个基础。 | WenqiLi #x0002A LiWang #x0002A XinleiSheng #x0002A ChuangyeYan RuiZhou JingHang PingYin NiengYan | 2013 | Cell Research2013，，12： | 10 |
| 2 | The Metabolism of Methylene Blue and Its Derivatives in Japanese Eel(Anguilla Japonica)显示文摘Methylene blue(MB) is commonly used in aquaculture as a fungicide and antidotes. This study was designed to explore the pharmacokinetics of MB in Japanese eel(Anguilla Japonica) immersed in 10 mg L^-1 and 20 mg L^-1 MB for 0.5 h. The concentrations of MB and its derivatives in the blood, liver, kidney, skin and muscle were determined by HPLC after immersion. The results showed that the changes of drug concentrations in Japanese eel were basically the same in different dose groups, showing a general trend of increasing at first and then decreasing, but the peak time was slightly different. The peak concentration of the drug was positively correlated with the dose level. The peak concentrations of MB in MB(20 mg L^-1) group, MB, azure A and azure B in the tissues of Japanese eel were significantly higher than those in MB(10 mg L^-1) group. Moreover, MB, azure A and azure B remained for a long time and could still be detected at 64 days, and azure C was not detected in tissues. | WANG Yali HUANG Xuanyun DU Bingtan LV Xinmei SUN Jing ZHENG Ruizhou HU Kun | 2020 | Journal of Ocean University of China2020，19，3： | 1 |
| 3 | Preload characteristics identification of the piezoelectric- actuated 1-DOF compliant nanopositioning platform显示文摘包装压电的陶器的致动器(PPCA ) 和顺从的机制为 nanopositioning 和 nanomanipulation 是吸引人的由于他们的超离频精确。创造并且保留在 PPCA 和顺从的机制的两结束之间的一个合适、稳定的连接的方法是完成如此的高精确性的必要的步。连接地位影响移动板,放的精确性和 nanopositioning 平台的动态性能的终端的起始的位置,特别在一个长期或高周波的放的过程期间。这份报纸论述一篇小说外部预装机制和测试它在自由(1-DOF ) 的 1 度顺从的 nanopositioning 站台。1-DOF 站台利用指导机制和平行四边形负担机制提供更精确的实际输入排水量和产量排水量的一个平行四边形。模拟结果验证建议僵硬模型和站台的动态模型。preload 排水量,实际输入排水量和输出排水量的值能被三个电容的传感器在完整的放过程期间测量。测试结果显示出 preload 特征与不同类型或 PPCA 的控制模式变化。一些恰当的公式被导出用 PPCA 的名字的延伸信号描述 preload 排水量,实际输入排水量和产量排水量。与 preload 特征的鉴定, PPCA 的实际、全面的产量特征能被在 PPCA 嵌入的紧张计量器传感器(SGS ) 获得。 | Ruizhou WANG Xianmin ZHANG | 2015 | Frontiers of Mechanical Engineering2015，10，1： | 1 |
| 4 | Molecular structure and vibrational spectra of phenobaraitone by density functional theory and ab initio hartree-Fock calculations显示文摘Quantum chemistry calculations have been performed using Gaussian03 program to compute optimized geometry,harmonic vibrational frequency along with intensities in IR and Raman spectra at RHF/6-31++G^(**)and B3LYP/6-31++G^(**)levels for phenobarbitone(C12H12N2O3)in the ground state.The scaled harmonic vibrational frequencies have been compared with experimental FT-IR and FT-Raman spectra.Theoretical vibrational spectra of the title compound were interpreted by means of potential energy distributions(PEDs)using MOLVIB program.A detailed interpretation of the infrared spectra of the title compound is reported.On the basis of the agreement between the calculated and observed results,the assignments of fundamental vibrational modes of phenobarbitone were examined and some assignments were proposed.The theoretical spectrograms for FT-IR and FT-Raman spectra of the title compound have been constructed. | Ruizhou ZHANG Xiaohong LI Xianzhou ZHANG | 2011 | Frontiers of Chemistry in China2011，6，4： | 0 |
| 5 | Theoretical investigation of some O-nitrosyl carboxylate biologic molecules——A natural bond orbital study显示文摘Theoretical study of several O-nitrosyl carboxylate compounds have been performed using quantum computational ab initio RHF and density functional B3LYP and B3PW91 methods with 6-31G^(**) basis set.Geometries obtained from DFT calculations were used to perform the natural bond orbital(NBO)analysis.It is noted that weakness in the O_(3)-N_(2) bond is due to nO_(1)→σO_(3)-N_(2) delocalization and is responsible for the longer O_(3)-N_(2) bond lengths in O-nitrosyl carboxylate compounds.It is also noted that decreased occupancy of the localized σO_(3)-N_(2) orbital in the idealized Lewis structure,or increased occupancy of σO_(3)-N_(2) of the non-Lewis orbital,and their subsequent impact on molecular stability and geometry(bond lengths)are related with the resulting p character of the corresponding sulfur natural hybrid orbital(NHO)of σ_(O_(3)-N_(2)) bond orbital.In addition,the charge transfer energy decreases with the increase of the Hammett constants of subsitutent groups. | Ruizhou ZHANG Zhenguo LI Xiaohong LI Xianzhou ZHANG | 2011 | Frontiers of Chemistry in China2011，6，2： | 0 |
