Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Online verification of adjustable robust optimization for electric hydrogen integrated energy systems with comprehensive demand response

International Journal of Electrical Power & Energy Systems
Traditional energy systems are gradually transitioning to new energy systems dominated by clean sources such as wind, solar, and hydrogen. As the penetration of renewable energy increases, the high uncertainty in their output presents significant ...

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

FEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

Biohydrogen Production from Xylose by Aanaerobic Mixed Cultures in Elephant Dung

Walailak Journal of Science and Technology, 2014
Xylose was used to produce hydrogen by anaerobic mixed cultures in elephant dung. The elephant dung was subjected to heat shock (90 ºC for 3 h) and acid (pH 3.0 - 4.0 for 24 h followed by neutralization) pretreatments before using it as a seed inoculum ...

Aquaporin‐3 and aquaporin‐5 impact the development of pancreatic ductal adenocarcinoma spheroids

FEBS Open Bio, EarlyView.
Schematic representation of the role of aquaporin‐3 (AQP3) and aquaporin‐5 (AQP5) in pancreatic ductal adenocarcinoma (PDAC). Both proteins are upregulated in PDAC and are associated with tumor progression and metastatic potential. Silencing AQP3 or AQP5 in PDAC spheroids results in decreased diameter, area, and overall growth, underscoring their key ...

Microwave-assisted acid and alkali pretreatment of Napier grass for enhanced biohydrogen production and integrated biorefinery potential

Chemical Engineering Journal Advances
Napier grass, a promising lignocellulosic energy crop, presents a complex composition that limits its bioconversion into fermentable products. To address this challenge, we applied microwave (MW) pretreatment assisted by acid and alkali, using varying ...

Geothermal energy use in hydrogen production

Journal of Thermal Engineering, 2016
We propose the use of geothermal energy for hydrogen production and liquefaction, and investigate six possible models for accomplishing such a task. The models are studied thermodynamically in order to assess their performance for maximizing hydrogen ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Atomically precise catalysts design toward efficient waste plastic hydrogenolysis

Nature Communications
Hydrogenolysis of waste plastics offers a promising route to valorize them into fuels, light olefins, and aromatics (BTX). Despite extensive studies, rational catalyst design and process optimization remain challenging.

Synergistic Cr2O3 nanoparticle/Cu nanosheet heterojunction for highly efficient electrosynthesis of urea under ultralow applied potentials

Nano Research
Although Cu possesses many unique advantages for electrocatalytic CO2 reduction reaction (CO2RR), it is not suitable for electrosynthesis of urea from CO2 and NO3− because of high energy barriers for the formation of *COOH and *CO intermediates and C–N ...
