Visualized experimental study on the process of high-pressure gas jet impacting on liquid-water column [PDF]

AIP Advances
To investigate the interaction laws governing the interaction between a gas jet and a liquid medium during the process of liquid-balanced launching, and to elucidate the influence of high-temperature gas on the characteristics of the gas–liquid ...

Determination of carbamazepine in serum and saliva samples by high performance liquid chromatography with ultraviolet detection [PDF]

Vojnosanitetski Pregled, 2009
Background/Aim. Carbamazepine is antiepileptic drug widely used for the treatment of epilepsy. Due to low therapeutic index of carbamazepine there is a need for routine measuring its concentrations in biological fluids.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Quince Pomace: A Source of Fiber Products and Polyphenols

Chemistry Proceedings, 2023
Quince fruits are used to make jams, jellies, and juices, resulting in by-products like seeds, pulp, and skin. These by-products contain bioactive compounds such as phenolic acids, flavonoids, and polysaccharides, which offer potential health benefits ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Short-Range Structural Transformations in Water at High Pressures

, 2011
We report results of molecular dynamics simulations of liquid water at the temperature T=277 K for a range of high pressure. One aim of the study was to test the model Amoeba potential for description of equilibrium structural properties and dynamical ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
