Advances on research of H2S removal by deep eutectic solvents as green solvent

Natural Gas Industry B
H2S in natural gas and other industrial gas is seriously harmful to human health, environmental protection and the downstream industries. Efficient purification of H2S containing gas is the basic process in the chemical industry. Benefiting from multiple

Produção de sulfato de amônio duplamente marcado com os isótopos estáveis 15N e 34S Production of ammonium sulfate doubly labeled with the 15N and 34S stable isotopes

Química Nova, 2005
The purpose of this work was the production of ammonium sulfate double labeled with 15N and 34S ((15NH4)2(34)SO4)), employing the ion exchange technique in two different processes. The first one was carried out using Na2(34)SO4 and (15NH4)2SO4 previously

A yeast model of 5‐oxoproline accumulation reveals a general toleration to 5‐oxoproline

FEBS Open Bio, EarlyView.
Using a yeast model, we show that even high accumulation of 5‐oxoproline causes only mild cellular stress and does not trigger oxidative stress. Instead, cells adapt by activating efflux pumps and diverse protective pathways, suggesting that previously proposed harmful effects of 5‐oxoproline may arise from indirect metabolic imbalances rather than the

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 ...

Surface-engineered polymer brush gate electrodes enable high-sensitivity label-free glucose detection via organic electrochemical transistor

Sensors and Actuators Reports
Non-enzymatic glucose detection remains challenging due to poor selectivity and instability in complex biological environments. Here, we developed an organic electrochemical transistor (OECT) incorporating a CH2Cl2-derived poly(EDOT-FPBA) gate to enhance

Lipopolysaccharide uptake is augmented in lipopolysaccharide‐tolerant mouse macrophage‐like cells via increased CD14 expression

FEBS Open Bio, EarlyView.
In normal (nontolerant) cells, CD14 is crucial for both LPS uptake and LPS signaling. In LPS‐tolerant cells, in which LPS‐induced TNF‐α and IFN‐β production is suppressed, there is a dramatic increase in surface CD14 expression. The overexpressed CD14 in LPS‐tolerant cells is responsible for the enhanced LPS uptake without inducing pro‐inflammatory ...

Mechanism of Iron–Sulfur Cluster Assembly: In the Intimacy of Iron and Sulfur Encounter

Inorganics, 2020
Iron–sulfur (Fe–S) clusters are protein cofactors of a multitude of enzymes performing essential biological functions. Specialized multi-protein machineries present in all types of organisms support their biosynthesis.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.
