Kim, Jeongmin; Savoie, Brett M.; Miller, Thomas F. III published the artcile< Interfacial Electron Transfer and Ion Solvation in the Solid Electrolyte Interphase>, Electric Literature of 112-63-0, the main research area is interfacial electron transfer ion solvation battery solid electrolyte interphase; atomic resolution simulation solid polymer liquid electrolyte solvation.

As a chem. and structurally well-defined model for redox processes in the solid electrolyte interphase of battery electrodes, we investigate electron transfer (ET) to lithium ions at the interface between a platinum metal anode and a solid polymer electrolyte. Studied electrolytes include LiTFSI (lithium bis(trifluoromethane)sulfonimide) salts in polyethylene oxide and poly(diethylene oxide-alt-oxymethylene), as well as in the associated liquid electrolytes 1,2-dimethoxyethane and tetraglyme. Atomic-resolution simulations are performed with constant-potential polarizable electrodes to characterize interfacial ET kinetics, including lithium-ion solvation structures and solvent reorganization effects as a function of applied electrode potential. The linear-response assumptions of the Marcus theory for ET are found to be robust in these systems, yet ion-solvation behavior at the anode interface is strikingly dependent on chain connectivity, solvation environment, and the magnitude of the applied electrode potential, resulting in very different ET kinetics for lithium electroreduction

Isaacs-Ten, Anna; Moreno-Gonzalez, Mar; Bone, Caitlin; Martens, Andre; Bernuzzi, Federico; Ludwig, Tobias; Hellmich, Charlotte; Hiller, Karsten; Rushworth, Stuart A.; Beraza, Naiara published the artcile< Metabolic Regulation of Macrophages by SIRT1 Determines Activation During Cholestatic Liver Disease in Mice>, COA of Formula: C19H34O2, the main research area is cholestatic liver disease autophagy SIRT1 macrophage metabolic regulation; Cholestasis; Inflammasome; Macrophages; Metabolism; SIRT1.

Inflammation is the hallmark of chronic liver disease. Metabolism is a key determinant to regulate the activation of immune cells. Here, we define the role of sirtuin 1 (SIRT1), a main metabolic regulator, in controlling the activation of macrophages during cholestatic liver disease and in response to endotoxin. We have used mice overexpressing SIRT1, which we treated with i.p. lipopolysaccharides or induced cholestasis by bile duct ligation. Bone marrow-derived macrophages were used for mechanistic in vitro studies. Finally, PEPC-Boy mice were used for adoptive transfer experiments to elucidate the impact of SIRT1-overexpressing macrophages in contributing to cholestatic liver disease. We found that SIRT1 overexpression promotes increased liver inflammation and liver injury after lipopolysaccharide/GalN and bile duct ligation; this was associated with an increased activation of the inflammasome in macrophages. Mechanistically, SIRT1 overexpression associated with the activation of the mammalian target of rapamycin (mTOR) pathway that led to increased activation of macrophages, which showed metabolic rewiring with increased glycolysis and broken tricarboxylic acid cycle in response to endotoxin in vitro. Activation of the SIRT1/mTOR axis in macrophages associated with the activation of the inflammasome and the attenuation of autophagy. Ultimately, in an in vivo model of cholestatic disease, the transplantation of SIRT1-overexpressing myeloid cells contributed to liver injury and fibrosis. Our study provides novel mechanistic insights into the regulation of macrophages during cholestatic disease and the response to endotoxin, in which the SIRT1/mTOR crosstalk regulates macrophage activation controlling the inflammasome, autophagy and metabolic rewiring.

Enuh, Blaise Manga; Aytar Celik, Pinar published the artcile< Insight into the biotechnology potential of Alicyclobacillus tolerans from whole genome sequence analysis and genome-scale metabolic network modeling.>, HPLC of Formula: 112-63-0, the main research area is Alicyclobacillus carbohydrates bioinformatics biotechnol network modeling; Acidophiles; Alicyclobacillus tolerans; Extreme environment; Genome-scale metabolic network model; Iron oxidation; Whole-genome sequence.

Extremophilic bacteria have numerous uncovered biotechnol. potentials. Acidophilic bacteria are important iron oxidizers that are valuable in bioleaching and in studying extreme environments on earth and in space. Despite their obvious potential, little is known about the genetic traits that underpin their metabolic functions, which are equally poorly understood from a mechanistic perspective. Novel bioinformatics and computational biol. pipelines can be used to analyze whole genomes to obtain insights into the phenotypic potential of organisms as well as develop a math. model representation of metabolism Whole-genome sequence anal. and a genome-scale metabolic network model was curated for an iron-oxidizing bacterium initially isolated from an acid mine drainage in Turkey, previously identified as Alicyclobacillus tolerans. The genome contained a high proportion of genes for energy generation from carbohydrates, amino acids synthesis and conversion, nucleic acid metabolism and repair which contribute to robust adaptation to their extreme environments. Several candidate genes for pyrite metabolism, iron uptake, regulation and storage, as well as genes for resistance to important heavy metals were annotated. A curated genome-scale metabolic network anal. accurately predicted facultative anaerobic growth, heterotrophic characteristics, and growth on a wide variety of carbon sources. This is the first in-depth in silico anal. of A. tolerans to the best of our knowledge which is expected to lay the groundwork for future research and drive innovations in environmental microbiol. and biotechnol. applications. The genomic data and mechanistic framework will have applications in biomining, synthetic geomicrobiol. on earth, as well as for space exploration and settlement.

Journal of Microbiological Methods published new progress about Alicyclobacillus tolerans. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, HPLC of Formula: 112-63-0.

Bagriantsev, Sviatoslav N.; Ang, Kean-Hooi; Gallardo-Godoy, Alejandra; Clark, Kimberly A.; Arkin, Michelle R.; Renslo, Adam R.; Minor, Daniel L. published the artcile< A High-Throughput Functional Screen Identifies Small Molecule Regulators of Temperature- and Mechano-Sensitive K2P Channels>, Category: esters-buliding-blocks, the main research area is screening small mol temperature K2P potassium channel yeast.

K2P (KCNK) potassium channels generate “”leak”” potassium currents that strongly influence cellular excitability and contribute to pain, somatosensation, anesthesia, and mood. Despite their physiol. importance, K2Ps lack specific pharmacol. Addressing this issue has been complicated by the challenges that the leak nature of K2P currents poses for electrophysiol.-based high-throughput screening strategies. Here, we present a yeast-based high-throughput screening assay that avoids this problem. Using a simple growth-based functional readout, we screened a library of 106,281 small mols. and identified two new inhibitors and three new activators of the mammalian K2P channel K2P2.1 (KCNK2, TREK-1). By combining biophys., structure-activity, and mechanistic anal., we developed a dihydroacridine analog, ML67-33, that acts as a low micromolar, selective activator of temperature- and mechano-sensitive K2P channels. Biophys. studies show that ML67-33 reversibly increases channel currents by activating the extracellular selectivity filter-based C-type gate that forms the core gating apparatus on which a variety of diverse modulatory inputs converge. The new K2P modulators presented here, together with the yeast-based assay, should enable both mechanistic and physiol. studies of K2P activity and facilitate the discovery and development of other K2P small mol. modulators.

Zosangpuii, Christina; Datta, Swagata; Gunindro, Ngangom; Meena, Dn; Nameirakpam, Surjit Singh published the artcile< Adverse drug reaction patterns of anti-retroviral drugs: a study in a tertiary care teaching institute of North East India>, Category: esters-buliding-blocks, the main research area is antiretroviral therapy adverse drug reaction pharmacovigilance age gender.

The use of antiretroviral drugs is associated with significant safety concerns but there is still insufficient data about the toxicity profile of antiretroviral therapy (ART) drugs especially in developing countries. Hence, this study was done to describe the severity and pattern of different types of adverse drug reactions that occurs with ART. A retrospective cross-sectional study was done at Pharmacovigilance center Regional Institute of Medical Sciences utilizing data from Jan. 2016 to Dec. 2019. A total of 190 cases reported during the study period were included in this study. Incidence was higher in females (109) as compared to males (81). The most common regimen responsible was Tenofovir/Lamivudine/Efavirenz (TLE) (69.5%) followed by Zidovudine/Lamivudine/Nevirapine (ZLN) (16.3%). Involvement of dermatol. system (27.4%) was most common. The most common Adverse drug reaction (ADR) associated with TLE was skin rash (28.3%) which was less severe as compared to the most common ADR associated with ZLN, which was anemia (40.6%). On evaluation of the World Health Organization-Uppsala Monitoring Center causality of ADRs, majority were found to be possible (78.2%). TLE regimen requires special focus as it was the most common regimen causing ADR but patients on ZLN regimen need to be closely monitored as they were found to cause more serious ADRs. A more active pharmacovigilance is needed for better understanding of toxicities related to ART.
