Hypoxia modulates the purine salvage pathway and decreases red blood cell and supernatant levels of hypoxanthine during refrigerated storage

open access: yesHaematologica, 2017
Hypoxanthine catabolism in vivo is potentially dangerous as it fuels production of urate and, most importantly, hydrogen peroxide. However, it is unclear whether accumulation of intracellular and supernatant hypoxanthine in stored red blood cell units is

Study on the efficacy of compound porcine cerebroside and ganglioside injection in patients with ischemic stroke: A randomized, single‐center, open‐label, prospective study

open access: yesIbrain, EarlyView., 2023
Compound porcine perebroside and ganglioside injection (CPCGI) was used to treat ischemic stroke. However, there was no clinical evidence of low‐dose CPCGI. We conducted a clinical study to analyze whether the clinical results of low‐dose and standard‐dose CPCGI in patients with ischemic stroke were different.

Purine nucleoside phosphorylase: A new marker for free oxygen radical injury to the endothelial cell [PDF]

open access: yes, 1990
The effect of ischemia and reperfusion on purine nucleoside phosphorylase was studied in an isolated perfused rat liver model. This enzyme is localized primarily in the cytoplasm of the endothelial and Kupffer cells; some activity is associated with the ...

A study of the effects of exercise on the urinary metabolome using normalisation to individual metabolic output [PDF]

open access: yes, 2015
Aerobic exercise, in spite of its multi-organ benefit and potent effect on the metabolome, has yet to be investigated comprehensively via an untargeted metabolomics technology.

THE ESTIMATION OF HYPOXANTHINE [PDF]

open access: yesJournal of Biological Chemistry, 1942
In a previous paper there was described a procedure for the isolation of the purines in a form suitable for the quantitative determination of the individual substances (1). A later publication reported a method for the separation of adenine and hypoxanthine and the determination of the adenine by precipitation of adenine picrate and titration of the ...

Hypoxanthine Secretion from Human Adipose Tissue and its Increase in Hypoxia

open access: yesObesity, 2018
The production of uric acid in murine white adipose tissue (mWAT), and that such production was augmented in obese mice, was recently reported. However, little is known about the secretion of metabolites associated with purine catabolism in human WAT ...

Development and Validation of a Simple High Performance Liquid Chromatography/UV Method for Simultaneous Determination of Urinary Uric Acid, Hypoxanthine, and Creatinine in Human Urine

open access: yesInternational Journal of Analytical Chemistry, 2018
Uric acid and hypoxanthine are produced in the catabolism of purine. Abnormal urinary levels of these products are associated with many diseases and therefore it is necessary to have a simple and rapid method to detect them.
