Noble metal-based metallenes are attracting intensive attention in energy catalysis, but it is still very challenging to precisely control the surface structures of for higher catalytic properties on account their intrinsic thermodynamic instability. Herein, synthesis tensile-strained holey Pd metallene by oxidative etching reported using hydrogen peroxide, which exhibits highly enhanced activity and stability comparison with normal toward both oxygen reduction reaction formic acid...

Metabolomics technology has enabled an important method for the identification and quality control of Traditional Chinese Medical materials. In this study, we isolated metabolites from cultivated Dendrobium officinale huoshanense stems different growth years in methanol/water phase identified them using gas chromatography coupled with mass spectrometry (GC-MS). First, a metabolomics platform was constructed. The were mainly sugars glycosides, amino acids, organic alcohols. D. their...

An ethyl acetate (EtOAc) extract isolated from the marine bacterium, Rheinheimera aquimaris QSI02, was found to exhibit anti-quorum sensing (anti-QS) activity. A subsequent bioassay-guided isolation protocol led detection of an active diketopiperazine factor, cyclo(Trp-Ser). Biosensor assay data showed that minimum inhibitory concentration (MIC) cyclo(Trp-Ser) ranged 3.2 mg/ml 6.4 mg/m for several microorganisms, including Escherichia coli, Chromobacterium violaceum CV026, Pseudomonas...

Six new prenylated polyhydroxy-p-terphenyl metabolites, named prenylterphenyllins A−C (1−3) and prenylcandidusins (5−7), one with a simple tricyclic C-18 skeleton, 4′′-dehydro-3-hydroxyterphenyllin (4), were obtained together eight known analogues (8−15) from Aspergillus taichungensis ZHN-7-07, root soil fungus isolated the mangrove plant Acrostichum aureum. Their structures determined by spectroscopic methods, their cytotoxicity was evaluated using HL-60, A-549, P-388 cell lines. Compounds...

Bacterial quorum sensing (QS) is anticipated as a new potential target for the development of antimicrobial drugs. An anti-QS substance against Chromobacterium violaceum CV026 and Pseudomonas aeruginosa PA01 has been isolated purified from crude extracts marine fungus Penicillium chrysogenum DXY-1, accurate structure was identified cyclo(l-Tyr-l-Pro). This cyclic dipeptide at sub-minimum inhibitory concentration can decrease QS-regulated violacein production C. by 79% QS-mediated pyocyanin...

Abstract Sphingans, a group of structurally closely related bacterial exopolysaccharides produced by members the genus Sphingomonas, can be applied in variety industries such as food, cement, and personal care applications due to their high viscosity. A sphingan-producing-bacterium, Sphingomonas sp. WG secret large quantity sphingan designated WL. To enhance production WL, three-stage control strategy was highest WL reach 33.3 g/L. The rheological analysis showed that aqueous solution had...

Study Design: Hospital-based retrospective studyObjectives: To evaluate the pathogenetic features of traumatic spinal cord injury (TSCI) during 1999–2016 according to changed etiology with time, explore different characteristics patients suffered a TSCI 1999–2007 and 2008–2016 in Tianjin, China.Setting: Tianjin Medical University General HospitalMethods: In this study, medical records were obtained from Hospital (TMUGH) 1st January 1999 31th December 2016. Variables recorded, including age,...

A novel quorum sensing (QS) system was discovered in Serratia odorifera, the symbiotic bacterium of Hypsizygus marmoreus. This uses cyclo(Pro-Phe), cyclo(Pro-Tyr), cyclo(Pro-Val), cyclo(Pro-Leu), cyclo(Tyr-Leu), and cyclo(Tyr-Ile) as autoinducers. discovery is first attempt to characterize cyclic dipeptides QS signaling molecules S. odorifera improves classical theory. Significantly, except for these autoinducers can increase transcription level lignin-degrading enzyme genes H. The...

The densely glycosylated spike (S) protein highly exposed on severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) surface mediates host cell entry by binding to the receptor angiotensin-converting enzyme 2 (ACE2). However, role of glycosylation has not been fully understood. In this study, we investigated effect different N-glycosylation S1 its ACE2. Using real-time plasmon resonance assay negative effects were demonstrated considerable increase affinities de-N-glycosylated proteins...

In the course of our research on utilizing edible flower resources to promote health, five ellagitannins (1–5) were isolated from pomegranate (Punica granatum L.) by bioassay-guided fractionation. Among them, mallotusinin (1) and tercatain (2) first flower, punicatannin D (4) was an unprecedented compound. Compounds 1–3 exhibited significant xanthine oxidase (XO) inhibitory activity compared with allopurinol, a potent inhibition α-glucosidase that superior acarbose observed for compounds...

The MnII(HCO3-)-H2O2 (MnII-BAP) system shows high reactivity toward oxidation of electron-rich organic substrates; however, the predominant oxidizing species and its formation pathways involved in MnII-BAP are still under debate. In this study, we used to oxidize As(III) that As(III), Mn2+, HCO3- common components As(III)-contaminated groundwater. Kinetic results show MnII(HCO3-)n [including MnII(HCO3)+ MnII(HCO3)2] is a key factor As(III). Quenching experiments rule out contributions OH•...

Liquid–liquid equilibrium (LLE) data for the ternary mixture of water + 2,2,3,3-tetrafluoro-1-propanol (TFP) {1-pentanol or 2-ethyl-1-hexanol n-propyl acetate dichloromethane} was measured in 101.3 KPa and 303.2 K. The distribution coefficient separation factor appraised utility extracting TFP from water. experimental LLE were related by nonrandom two liquid universal quasichemical models which absolute average deviation root means square no more than 0.0029 0.0035, respectively.
