Assay of the antioxidant capacity of foods using an iron(II)-catalysed lipid peroxidation model for greater nutritional relevance [PDF]

open access: yes, 2010
The formation of free radicals by the iron-catalysed Fenton reaction is a major cause of oxidative damage in the body. Here a common assay of antioxidant capacity, inhibition of the β-carotene-linoleic acid model of lipid peroxidation, has been modified ...

Selective elimination of quiescent cancer cells by dequalinium chloride via ROS‐mediated ferroptosis

open access: yesFEBS Open Bio, EarlyView.
Dequalinium chloride (DQ) selectively eliminates quiescent cancer cells (QCCs) by amplifying mitochondrial ROS. QCCs exhibit elevated basal ROS and limited redox‐buffering capacity, making them vulnerable to further ROS increases. DQ‐induced ROS exceeds the tolerance threshold, triggering lipid peroxidation and ferroptosis, whereas proliferating cells ...

Elevated Liver Enzymes Is Not an Impediment to Allopurinol Dose Escalation: An Observational Cohort Study

open access: yesArthritis Care &Research, EarlyView.
Objective Routine liver enzyme monitoring is advocated for while on allopurinol, but supporting guidance is lacking. We assessed the incidence and factors associated with elevated liver enzyme levels in patients with gout commenced on allopurinol. Methods One hundred and fifty patients with gout and normal baseline serum aminotransferases initiated on ...
