Lipid peroxidation is a nonparenchymal cell event with reperfusion after prolonged liver ischemia [PDF]

, 1990
A proposed mechanism for irreversible ischemic liver damage has been peroxidation of membrane phospholipids by free radicals. However, the hepatocyte is laden with enzymes which are antioxidants and, therefore, ought to be relatively resistant to ...

The mechanism and significance of the conversion of xanthine dehydrogenase to xanthine oxidase in mammalian secretory gland cells

Redox Biology, 2023
The conversion of xanthine dehydrogenase (XDH) to xanthine oxidase (XO) occurs only in mammalian species. In fresh bovine milk, the enzyme exists predominantly as the oxidase form, in contrast to various normal organs where it is found primarily as the ...

The essential roles of metal ions in insect homeostasis and physiology [PDF]

, 2017
Metal ions play distinct roles in living organisms, including insects. Some, like sodium and potassium, are central players in osmoregulation and ‘blood and guts’ transport physiology, and have been implicated in cold adaptation.

Response to allopurinol and febuxostat according to the fractional excretion of urate in men with gout

Arthritis Care &Research, Accepted Article.
Background Body mass index (BMI), glomerular filtration rate (GFR), and pretreatment urate levels have been reported to influence the urate‐lowering response to allopurinol. We investigated whether the fractional excretion of urate (FEUA) also modulates this response and relates to oxypurinol concentrations. We further evaluated its potential influence

Enantioconvergent Access to Chiral S(VI) Stereocenters by Kinetic Resolution of Sulfonimidoyl Chlorides

Angewandte Chemie, EarlyView.
An enantioconvergent approach for the kinetic resolution of S(VI) stereocenters that leverages the electrophilic reactivity of the chiral sulfur atom is described. The catalytic process provides access to sulfonimidoyl chlorides and sulfonimidates, which are among the least studied S(VI) functionalities.

PENGHAMBATAN AKTIVITAS XANTHINE OXIDASE OLEH EKSTRAK ETANOL SARANG SEMUT (Myrmecodia tuberosa (non Jack) Bl.) SECARA IN VITRO

Pharmaciana, 2014
Uric acid is the end product of purine metabolism that can settle in the joints and form small crystals, causing inflammation known as gout. Gout is a disease caused by high levels of uric acid in the blood (hyperuricemia).

Zinc‐Coordinated Trienzyme Nanogel Cascade Therapy for Accelerated Post‐Pancreatectomy Cutaneous Wound Healing

Advanced Materials, EarlyView.
A zinc‐coordinated nanogel assembly is reported that co‐delivers three enzymes to regulate glucose, oxidative stress, and oxygen levels. This system mimics natural enzyme cascades to reprogram the wound environment after pancreatectomy. In a post‐pancreatectomy mouse model, it accelerates healing by reducing infection, promoting blood vessel growth ...
