Crucial involvement of xanthine oxidase in the intracellular signalling networks associated with human myeloid cell function [PDF]
Xanthine oxidase (XOD) is an enzyme which plays a central role in purine catabolism by converting hypoxanthine into xanthine and then further into uric acid.

Biochemistry Changes That Occur after Death: Potential Markers for Determining Post-Mortem Interval [PDF]
Death is likely to result in very extensive biochemical changes in all body tissues due to lack of circulating oxygen, altered enzymatic reactions, cellular degradation, and cessation of anabolic production of metabolites.

When cellular iron is low, bacterioferritin (Bfr) releases its stored iron through a reductive process dependent on the [2Fe–2S] ferredoxin Bfd. Why accessing stored iron should depend on an iron‐requiring protein when iron is scarce is unclear. Here, we show that the Bfd [2Fe–2S] cluster is sensitive to oxidative stress, suggesting that it may act as ...

First case of hereditary xanthinuria in a Moroccan family
The xanthinuria is a rare hereditary autosomal recessive disease. It is related to xanthine oxidase deficiency also known as xanthine dehydrogenase, an enzyme involved in the metabolism of purine bases.
