Livogrit ameliorates acetaldehyde-induced steatosis in HepG2 cells through modulation of lipogenesis and β-oxidation pathways

Phytomedicine Plus, 2021
Background: Frequent alcohol consumption leads to development of alcoholic liver steatosis. Onset of steatosis is caused by alcohol metabolite ‘acetaldehyde’ causing intracellular accumulation of lipid bodies due to abnormal metabolism. Livogrit is a tri-

Metal‐Support Interaction Triggered Electronic Reconstruction in Pd/CoN‐Co4N Catalysts for Optimizing MEK Oxidation and Poisoning Resistance

Advanced Science, EarlyView.
The strengthened EMSI in Pd/CoN‐Co4N induces electronic rearrangement, generating abundant Pd0 species in situ, modulating the Pd d‐band center to enhance O2 adsorption and MEK activation. Concurrently, it creates numerous Lewis acid sites that preferentially adsorb poisons and shield the active sites.

Construction of Sabatier Volcanoes for CO2 Hydrogenation to C1‐2 Oxygenates Using Data‐Efficient Machine Learning

Advanced Science, EarlyView.
A new data‐efficient framework combining DFT calculations, a neural network model, and automated graph analysis of catalytic reaction networks is proposed and applied to CO2 hydrogenation on transition metal nanoparticles. The analysis shows how efficient C2 oxygenate production requires a balance between CHx formation, C–C coupling, protonation, and ...

Chronic alcohol consumption compromises gut barrier integrity and promotes endotoxemia: Implications for sepsis susceptibility in immunocompromised hosts

Animal Models and Experimental Medicine, EarlyView.
Chronic alcohol exposure disrupts intestinal barrier integrity, resulting in a leaky gut and enhanced translocation of lipopolysaccharide (LPS) and microbial products into the systemic circulation. Alcohol‐induced endotoxemia drives exaggerated pro‐inflammatory responses, mitochondrial damage, and activation of the cGAS–STING pathway, particularly in ...

Plant physiological and environmental controls over the exchange of acetaldehyde between forest canopies and the atmosphere [PDF]

Biogeosciences, 2008
We quantified fine scale sources and sinks of gas phase acetaldehyde in two forested ecosystems in the US. During the daytime, the upper canopy behaved as a net source while at lower heights, reduced emission rates or net uptake were observed.

Detrimental effects of ethanol and its metabolite acetaldehyde, on first trimester human placental cell turnover and function. [PDF]

PLoS ONE, 2014
Fetal alcohol spectrum disorder (FASD) describes developmental issues from high maternal alcohol intake, which commonly results in fetal growth restriction and long term morbidity.

High-level expression of an acetaldehyde dehydrogenase from Lactiplantibacillus plantarum and preliminary evaluation of its potential as a functional food additive

Electronic Journal of Biotechnology, 2023
Background: Acetaldehyde dehydrogenase (ALDH) is a common oxidoreductase and one of the aldehyde dehydrogenases, which can convert toxic acetaldehyde to harmless acetyl CoA.

Ein Ruthenium‐(Ph‐BPE) Katalysator für die asymmetrische Alkinylierung von Fluoral: Enantioselektion aus einem von 12 fluxionalen Komplexen mit rutheniumzentrierter Stereogenität

Angewandte Chemie, EarlyView.
Dies beschreibt die ersten enantioselektiven Alkinylierungen wässrigen Fluorals. Diese Prozesse werden durch einen Iodid‐gebundenen Ruthenium‐(Ph‐BPE)‐Komplex katalysiert, welcher als oktaedrischer Metallkomplex in 12 verschiedenen stereoisomeren Formen vorliegen kann.

Alcohol Metabolizing Enzymes, Microsomal Ethanol Oxidizing System, Cytochrome P450 2E1, Catalase, and Aldehyde Dehydrogenase in Alcohol-Associated Liver Disease

Biomedicines, 2020
Once ingested, most of the alcohol is metabolized in the liver by alcohol dehydrogenase to acetaldehyde. Two additional pathways of acetaldehyde generation are by microsomal ethanol oxidizing system (cytochrome P450 2E1) and catalase.

A Ruthenium‐(Ph‐BPE) Catalyst for Asymmetric Alkynylation of Fluoral: Enantioselection From 1 of 12 Fluxional Stereogenic‐at‐Ruthenium Complexes

Angewandte Chemie International Edition, EarlyView.
The first enantioselective alkynylations of aqueous fluoral are described. These processes are catalyzed by an iodide‐bound ruthenium‐(Ph‐BPE)‐catalyst; an octahedral metal complex that can exist as 12 diastereomeric‐at‐metal isomers. Calculations reveal that 2 of 12 stereoisomeric complexes account for 99.9% of the Boltzmann population and that ...
