R Săndulescu et al.
Journal of pharmaceutical and biomedical analysis, 14(8-10), 951-958 (1996-06-01)
The method is based upon the reaction between fluoride ions and the coloured complex of Fe(III) with methyl salicylate to form the stable, colourless hexaflouride complex of iron. The conditions of the method (pH, time and combination ratio) were studied
S Puntarulo et al.
Archives of biochemistry and biophysics, 264(2), 482-491 (1988-08-01)
The interaction of microsomes with iron and NADPH to generate active oxygen radicals was determined by assaying for low level chemiluminescence. The ability of several ferric complexes to catalyze light emission was compared to their effect on microsomal lipid peroxidation

Neurobiology of aging, 25(1), 125-129 (2003-12-17)
In order to investigate whether amyloid beta-peptide-induced oxidative damage in the brain could be related to aging, we studied the release of 8-iso-prostaglandin (PG)F2alpha, a stable marker of cellular oxidative stress, in brain synaptosomes from Wistar rats of different ages

The Journal of nutrition, 116(6), 1007-1017 (1986-06-01)
The effects of pH, ascorbate, citrate and dietary fiber on retention of ferrous and ferric iron by jejuno-ileal segments of rat intestine were examined in vivo. Iron was introduced in an isosmotic solution of sodium chloride and dextrose buffered by

Diabetes mellitus is characterized by increased methylglyoxal (MG) production. The aim of the present study was to investigate the role of iron in the cellular and molecular effects of MG. A red blood cell (RBC) model and L-arginine were used
