Motivation: The coronavirus disease 2019 (COVID-19) caused by a new type of has been emerging from China and led to thousands death globally since December 2019. Despite many groups have engaged in studying the newly emerged virus searching for treatment COVID-19, understanding COVID-19 target-ligand interactions represents key chal-lenge. Herein, we introduce Docking Server, web server that predicts binding modes between targets ligands including small molecules, peptides anti-bodies....
An efficient electro-oxidative C–H/N–H activation with 1,3-diynes has been achieved a robust earth-abundant cobalt catalyst. The electrochemical C–H functionalization was accomplished ample scope and remarkable functional group compatibility in simple undivided cell. This protocol avoids the utilization of stoichiometric cost-intensive chemical oxidants activation, thus forming hydrogen as only byproduct.
During the deep-sea gas hydrate mining riser operation, vibration prediction is obtained using a simplified theoretical model, and its accuracy cannot be effectively guaranteed. Deep learning methods can solve this problem. Therefore, three-dimensional model for established long short-term memory network based on deep-learning, which trained with help of data in field, realize advance response later period. In order to verify correctness similar principle used develop an experimental rig...
Purpose: Most absorption enhancers boost the oral of drugs via increasing intestinal permeability. However, they often damage mucosa and induce inflammatory reactions. The aim this study is to synthesize a new enhancer, punicic acid ethyl ester (PAEE), with excellent absorption-prompting effect low toxicity. Methods: structure PAEE was confirmed by NMR, MS, IR UV. Setting oleic (OA) as control, three forms (PA), ie, free PA, PAEE, pomegranate seed oil, in which PA exists form triglyceride,...
During the lifting process of deep-sea natural gas hydrate, mining riser is susceptible to complex fatigue failure due combined effects internal gas–liquid–solid three-phase flow, external ocean loads, and large aspect ratio itself. The flow induced vibration (FIV) model for hydrate extraction established using finite element method Hamiltonian principle. simulation experimental device nonlinear under excitation developed conducted a experiment FIV vertical pipes. test results are compared...
In response to the problem of transient flow pressure fluctuations induced by opening and closing gas tree valves at a 175 MPa deep well wellhead, Christmas simulation experimental device capable effectively simulating on-site conditions was developed using principle similarity. By designing different gas–liquid ratios, rates, valve switch combinations, inside wellhead measured, influence parameters on two-phase in explored. It found that as ratio increases, drops faster, phase is prone...
Periplaneta americana extracts (PAEs) play a crucial role in skin wound healing. However, their molecular effects and signaling pathways regenerating tissues cells are not clear. In this study, we refined the PAE from to investigate mechanisms underlying The human keratinocyte line HaCaT was selected mouse model of deep second-degree thermal burn established for vitro vivo studies, respectively. treatment induced proliferation migration healing model. Furthermore, on were found depend...
Fritillaria cirrhosa D. Don is a renowned traditional Chinese medicine plant that mainly distributed in the southeastern margin of Qinghai–Tibet Plateau. The overexploitation recent years has led to sharp decline this undomesticated resource. Analyzing impact climate change on geographic distribution F. meaningful for its conservation and domestication. In study, maximum entropy model (Maxent) was used simulate relation current future climatic conditions. temperature warmest month (Bio 5)...
The dark black chafer, Holotrichia parallela , is an economically important pest in China and worldwide. Traps based on chemical communication are being developed as alternative control measure to pesticides for this pest, studies reveal mechanisms highly desirable. To systematically analyze genes potentially involved we generated a comprehensive transcriptome with combined samples derived from multiple tissues developmental stages. A total of 43,967 nonredundant sequences (unigenes) average...
Chitosan nanoparticles (CS‐NPs) without drug loading have diverse biological activity. In this study, we prepared CS‐NPs, CS‐NPs solidified by different amount of glutaraldehyde, and modified with either biotin (B‐CS‐NPs) or avidin (A‐B‐CS‐NPs) examined their cytotoxicity on HepG2 cells. The morphology size were measured transmission electron microscopy photon correction spectroscopy, respectively. extent solidification was validated the approach sonication. Biotin connect density surface...
In response to the problem of gas–liquid–solid three-phase flow in deep-sea hydrate extraction pipelines, a model considering dynamic decomposition hydrates is established using continuity equations, momentum and energy equations. The numerical solution theoretical achieved finite difference method.
