Establishing an assay to evaluate d‐amino acid oxidase enzyme kinetics and inhibition using WST‐8 redox dye

open access: yesFEBS Open Bio, EarlyView.
This study investigated a novel WST‐8‐based assay for evaluating d‐Amino acid oxidase (DAO) inhibitors. We confirmed its effectiveness using known inhibitors and found that uremic toxins possess relatively weak inhibitory activity compared to existing drugs.

Proteome-wide analysis of cysteine oxidation reveals metabolic sensitivity to redox stress [PDF]

open access: yes, 2018
Reactive oxygen species (ROS) are increasingly recognised as important signalling molecules through oxidation of protein cysteine residues. Comprehensive identification of redox-regulated proteins and pathways is crucial to understand ROS-mediated events.

Modified Potentiometric Method with Isooctane for Peroxide Value Determination

open access: yesJournal of Japan Oil Chemists' Society, 1994
The potentiometric method for determining peroxide value (PV) was modified by substituting an isooctane-acetic acid (1 : 4) mixture for a chloroform-acetic acid (2 : 3) mixture as the solvent, without loss of analytical precision and with increased convenience. Nitrogen replacement of air in a reaction flask was effective for this purpose.

Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

open access: yesAging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.

Effects of hole self-trapping by polarons on transport and negative bias illumination stress in amorphous-IGZO

open access: yes, 2017
The effects of hole injection in amorphous-IGZO is analyzed by means of first-principles calculations. The injection of holes in the valence band tail states leads to their capture as a polaron, with high self-trapping energies (from 0.44 to 1.15 eV ...

Air Pollution and the Risk and Progression of Multiple Sclerosis: A Systematic Review and Meta‐Analysis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Purpose Air pollution has been linked to several neurological conditions, including stroke and neurodegenerative diseases. Evidence regarding its association with multiple sclerosis (MS) remains conflicting, limited by small sample sizes. Methods PubMed, Embase, Scopus, and Cochrane controlled register of trials (CENTRAL) were searched on ...

ANTIOXIDANT ACTIVITY DETERMINATION IN A LIPIDIC PEROXIDATION MODEL OF BUTTER INHIBITED BY ISOESPINTANOL

open access: yesVitae, 2009
The antioxidant activity (Φ) is defined as the slope of the simple linear regression of φ0/φi against the concentration μM, in an inhibition model of lipid peroxidation of butter at 60° C, where φi is the concentration effect of isoespintanol and φ0 is ...
