Ding, Yu; Song, Xiuxian; Yu, Zhiming published the artcile< Transcriptome profiles of genes related to growth and virulence potential in Vibrio alginolyticus treated with modified clay>, Category: esters-buliding-blocks, the main research area is Vibrio alginolyticus modified clay growth virulence transcriptome profile gene; Growth; Modified clay; Transcriptome; Vibrio alginolyticus; Virulence.

Vibrio alginolyticus is a globally distributed opportunistic pathogen that causes different degrees of disease in various marine organisms, such as fish, shrimp and shellfish. At present, vibriosis caused by V. alginolyticus has a wide epidemic range and causes frequent outbreaks, resulting in substantial losses in aquaculture. According to previous studies, modified clay (MC) could effectively flocculate and reduce the d. of Vibrio in water, but it is still unknown whether MC inhibits growth and how it affects virulence in bottom flocs. Here, we studied the response mechanism of V. alginolyticus in flocs treated with MC at the transcriptome level and verified the transcriptomic data combined with relevant physiol. experiments and reverse transcription quant. real-time PCR (RT-qPCR) for the first time. It was found that the morphol. of Vibrio in the MC flocs changed, the membrane function was damaged, the antioxidant system was activated, and the material and energy metabolism also changed. In addition, MC could inhibit the expression of virulence factors of V. alginolyticus; for example, flagella, pilus, siderophores, quorum sensing, and other related genes were significantly downregulated. In general, MC effectively inhibited the growth of Vibrio and reduced its virulence potential in flocs, which could provide theor. support for a new model of healthy aquaculture.

Omairey, Eman L.; Zhang, Yuqing; Gu, Fan; Ma, Tao; Hu, Pengsen; Luo, Rong published the artcile< Rheological and fatigue characterization of bitumen modified by anti-ageing compounds>, Category: esters-buliding-blocks, the main research area is bitumen antiageing compound rheol fatigue characterization.

When exposed to the ambient environment for an extended period, bitumen ages and causes the failure of asphalt pavement, the addition of anti-ageing compounds (AACs) to bitumen binders can prolong the service life of the pavement. This study investigates the effects of anti-ageing compounds on the fatigue performance of bitumen when subjected to different ageing conditions. The AAC-modified bitumen binders were tested by dynamic shear rheometer (DSR) and Fourier transform IR spectroscopy test (FTIR) at different ageing conditions including unaged, short-term ageing by thin film oven test (TFOT) and long-term ageing by pressure ageing vessel (PAV). The fatigue performance of the AAC-modified bitumen was characterised by the dissipated energy ratio (DER), SHRP fatigue parameter and the DSR-cracking (DSR-C) approach developed by the authors. Linear amplitude sweep (LAS) tests were firstly run at 20°C, 10 Hz and 0.1-15% controlled shear strain conditions, to obtain the phase angles and shear moduli at the undamaged conditions. Time sweep (TS) tests were then conducted at 5% shear strain, also at 20°C and 10 Hz, and up to 24,000 loading cycles to obtain phase angles, shear moduli and DER at damaged conditions. The crack lengths in the TS tests were calculated by DSR-C model and then validated by the image anal. method. The results suggest that, compared to the DER or SHRP fatigue parameter, DSR-C predicted crack lengths show a more consistent and reliable agreement with laboratory measurements. DSR-C test can differentiate fatigue cracking performance among binders modified with AACs, and the normalized carbonyl index may be a reliable parameter to reflect the impact of ageing products on the fatigue resistance of AAC-modified binders. Bitumen samples modified with 12% (1 furfural: 5 Irganox 1076), 15% Irganox 1076 and 3.5% (3 DLTDP: 4 furfural) demonstrated the best anti-ageing behavior by retarding carbonyl content growth and decreasing the fatigue damage among selected AACs without sacrificing the stiffness of binder. However, rutting susceptibility at earlier stages of service life needs further investigations.

Morin, Matthew D.; Wang, Ying; Jones, Brian T.; Mifune, Yuto; Su, Lijing; Shi, Hexin; Moresco, Eva Marie Y.; Zhang, Hong; Beutler, Bruce; Boger, Dale L. published the artcile< Diprovocims: A New and Exceptionally Potent Class of Toll-like Receptor Agonists>, SDS of cas: 112-63-0, the main research area is diprovocim toll like receptor agonist antitumor neoplasm.

A screen conducted with nearly 100000 compounds and a surrogate functional assay for stimulation of an immune response that measured the release of TNF-α from treated human THP-1 myeloid cells differentiated along the macrophage line led to the discovery of the diprovocims. Unique to these efforts and of special interest, the screening leads for this new class of activators of an immune response came from a compound library designed to promote cell-surface receptor dimerization. Subsequent comprehensive structure-activity relationship studies improved the potency 800-fold over that of the screening leads, providing diprovocim-1 and diprovocim-2. The diprovocims act by inducing cell-surface toll-like receptor (TLR)-2 dimerization and activation with TLR1 (TLR1/TLR2 agonist), bear no structural similarity to any known natural or synthetic TLR agonist, and are easy to prepare and synthetically modify, and selected members are active in both human and murine systems. The most potent diprovocim (3, diprovocim-1) elicits full agonist activity at extraordinarily low concentrations (EC50 = 110 pM) in human THP-1 cells, being more potent than the naturally derived TLR1/TLR2 agonist Pam3CSK4 or any other known small mol. TLR agonist.

Zhang, Gangning; Lu, Shigang; Zhao, Shangqian; Zhang, Li; Sun, Haobo published the artcile< Revealing the Local Cathodic Interfacial Chemism Inconsistency in a Practical Large-Sized Li-O2 Model Battery with High Energy Density to Underpin Its Key Cyclic Constraints>, Electric Literature of 112-63-0, the main research area is lithium oxygen secondary battery cathode electrolyte interface overcharging; Li2CO3; LiAc·2H2O; high energy density; large-sized Li−O2 battery; local chemism inconsistency; rechargeability.

Due to the theor. ultrahigh energy d. of the Li-O2 battery chem., it has been hailed as the ultimate battery technol. Yet, practical Li-O2 batteries usually need to be designed in a large-sized pattern to actualize a high specific energy d., and such batteries often cannot be cycled effectively. To understand the inherent reasons, we specially prepared large-sized (13 cm x 13 cm) Li-O2 model batteries with practical energy output (6.9 Ah and 667.4 Wh/kgcell) for investigations. By subregional and postmortem anal., the cathode interface was found to have severe local inhomogeneity after discharge, which was highly associated with the electrolyte and O2 maldistribution. The quant. results by XPS evidenced that this local inhomogeneity can exacerbate the generation of lithium acetate during charge, where the locally higher ratio of unutilized carbon surface and less Li2O2 after discharge would result in increased lithium acetate formation for a subsequent local overcharge. Moreover, verification experiments proved that the byproduct lithium acetate, which had been of less concern, was recalcitrant and triggered much larger polarization compared with the commonly reported byproduct Li2CO3 during battery operations, further revealing the key limiting factors leading to the poor recharge-ability of batteries by its accumulation at a pouch-type cell level.

A variety of bifunctional catalysts are prepared combining immobilized metal nanoparticles and acid solid materials featuring Lewis or Bronsted acidity was reported. The catalytic systems are tested in the reductive amination of bio-derived levulinates with primary amines, using hydrogen as clean reducing agent, to obtain N-substituted-5-methyl-2-pyrrolidones, which were proposed as substitutes for the widely used, REACH-restricted solvent N-methyl-2-pyrrolidone. The overall process was studied in depth to identify the best combination of metal and acid functionalities to be used in one-pot and one stage. Pt immobilized onto the Bronsted solid acid Aquivion is shown to be the most efficient catalyst, with a productivity of N-heptyl-5-methyl-2-pyrrolidone of 7.9 mmolgcat-1 h-1 reached at full conversion and 98.6% selectivity, under 120°C, 4 bar H2 pressure and solvent-free conditions.

The use of computational chem. as an effective means of designing eco-friendly organic corrosion inhibitors has been greatly enhanced by the development of D. Functional Theory (DFT). In this study, the inhibitory activity of four antiretroviral drugs, namely, lamivudine, emtricitabine, didanosine and stavudine, was analyzed by this theory. The quantum chem. parameters/descriptors calculated using DFT at B3LYP/6-31G(d) level were used to explain the mechanism of electron transfer between the inhibitors and the copper surface. The results showed that these compounds adsorb on copper surface. It is important to consider the effect of films formed by the adsorption products. In addition, the Fukui functions and the dual descriptor were used as indicators to locate the electrophilic and nucleophilic attack sites within each compound Finally, the DFT has enabled to accurately predict the adsorption properties and the good inhibition performance of the mols. in the solution studied.

Shi, Honghui; Yang, Endian; Yang, Heyue; Huang, Xiaoling; Zheng, Mengxia; Chen, Xiaoyang; Zhang, Junjie published the artcile< Dynamic changes in the chemical composition and metabolite profiles of drumstick (Moringa oleifera Lam.) leaf flour during fermentation>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is Moringa Aspergillus Candida Bacillus carbohydrate amino acids myoinositol oligosaccharides.

Solid-state fermentation (SSF) using mixed strains can increase the nutritional value and antioxidant content of Moringa oliefera Lam. leaf flour (MLF). However, little is known about the chem. composition and metabolite profiles of MLF during the fermentation process. In this work, mixed strains of Aspergillus Niger, Candida utilis and Bacillus subtilis were inoculated into MLF for SSF. The MLF′s contents of crude protein (CP), crude fiber (CF), water soluble carbohydrate (WSC), reducing sugar, tannin and phytic acid all changed significantly as fermentation proceeded. A metabolomic anal. was performed using GC-TOF-MS, resulting in the identification of 347 metabolites. Fermentation with mixed strains significantly affected levels of amino acids, sugars, and organic acids; concentrations of most amino acids, oligosaccharides, organic acids, nucleosides, γ-aminobutyric acid (GABA), and myo-inositol were higher after 3 d of SSF than at the start. Addnl., several intermediate metabolites were detected in 3 d fermented MLF. The mixed microorganisms′ metabolic activity thus seems to peak after 3 d of fermentation under the tested conditions. These results provide new insights into the changes in the chem. composition and metabolite content of MLF during SSF and reveal possibilities for producing valuable compounds via this process.
