Dear editor,The stochastic singular system is also called the stochastic differential algebraic system, stochastic descriptor system, generalized stochastic system, and stochastic degenerate system (e.g.,[1–4]). This type of system is found in numerous fields of application, which include fluid dynamics, the modeling of multi-body mechanisms, finance, inputoutput economics and the problem of protein folding.

为实现植被固沙,设计了一种沙漠植树机器人,通过深度相机实现视觉跟随进而判断树坑标记点,将获取的信息反馈后通过计算得到运动路线,植树机器人抵达工作位置后通过控制电机实现挖坑装置的升降和钻头旋转,基于沙子的高流动性特征设计了树坑挖掘装置来减少进入树坑的回流沙,进而保证树坑的完整性,随后通过传送带将植被运输至树坑内,灌溉的同时带动后部的回填装置完成散沙回填,稳定植被。本设计可为新疆干旱沙漠化治理提供参考。

Arenobufagin is a novel isoform-specific probe for sensing human sulfotransferase 2A1

Acta Pharmaceutica Sinica B 2018年第5期8卷 784-794页

Human cytosolic sulfotransferase 2 A1(SULT2A1) is an important phase II metabolic enzyme. The detection of SULT2A1 is helpful for the functional characterization of SULT2A1 and diagnosis of its related diseases. However, due to the overlapping substrate specificity among members of the sulfotransferase family, it is difficult to develop a probe substrate for selective detection of SULT2A1. In the present study, through characterization of the sulfation of series of bufadienolides, arenobufagin(AB) was proved as a potential probe substrate for SULT2A1 with high sensitivity and specificity. Subsequently, the sulfation of AB was characterized by experimental and molecular docking studies. The sulfate-conjugated metabolite was identified as *** sulfation of AB displayed a high selectivity for SULT2A1 which was confirmed by in vitro reaction phenotyping assays. The sulfation of AB by human liver cytosols and recombinant SULT2A1 both obeyed Michaelis-Menten kinetics, with similar kinetic parameters. Molecular docking was performed to understand the interaction between AB and SULT2A1, in which the lack of interaction with Met-137 and Tyr-238 of SULT2A1 made it possible to eliminate substrate inhibition of AB sulfation. Finally, the probe was successfully used to determine the activity of SULT2A1 and its isoenzymes in tissue preparations of human and laboratory animals.
