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

, 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 ...

Xanthine Oxidase Inhibitory Activity of Some Vietnamese Remedies Used to Treat Bi Syndrome in Traditional Medicine

Natural Product Communications
Background Hyperuricemia is a metabolic disorder caused by abnormalities in purine metabolism that increase serum uric acid. Some traditional medicine remedies have been proven to cause hypouricemia by inhibiting xanthine oxidase.

Potential role of NADPH-oxidase in early steps of lead-induced oxidative burst in Vicia faba roots [PDF]

, 2008
The mechanism of oxidative burst induced by lead in Vicia faba excised roots was investigated by luminol-dependent chemiluminescence. Results showed that lead triggered a rapid and dose-dependent increase in chemiluminescence production.

Synthesized flavone attenuates diabetes‐induced neurodegeneration through regulation of oxidative stress and metabolic‐neurodegenerative molecular pathways

Ibrain, EarlyView.
Neuroprotective efficacy of flavone (2‐phenyl‐4H‐chromen‐4‐one). The study aimed to explore the potential of a synthetic derivative (flavone) of a phytocompound, which is involved in neuroprotection activities. Experimental strategies included the characteristics of compound, in‐silico analysis, and in vivo assessments.

Beyond “you are what you eat”: Unlocking gut microbiota‐mediated biotransformation of dietary phytochemicals

iMetaOmics, EarlyView.
The “efficacy paradox” of phytochemicals, low bioavailability yet significant health benefits, is associated with gut microbiota, which biotransforms dietary precursors into bioactive metabolites, enabling systemic effects. Thus, health outcomes of diet depend not just on intake “the rainbow”, but on gut microbial metabolism, redefining “you are what ...

Effect of ELF e.m. fields on metalloprotein redox-active sites

, 2007
The peculiarity of the distribution and geometry of metallic ions in enzymes pushed us to set the hypothesis that metallic ions in active-site act like tiny antennas able to pick up very feeble e.m. signals.
