A series of manganese(II) and manganese(III) salts and oxides were investigated for their ability to catalyze the autoxidation of sulfite resulting in oxidative damage to DNA. Experiments directed at identifying the reactive intermediates responsible for DNA oxidation included the trapping of a sulfite radical adduct during EPR studies, alcohol quenching studies of free radical intermediates, comparisons...
La solubilite et les phases en equilibre dans le systeme quaternaire Na + ,Mn 2+ /Cl - ,(H 2 PO 2 ) - //H 2 O sont etudiees par la methode isothermique a 25 o C, dans le but d'elaborer une methode pratique de preparation de l'hypophosphite de manganese par reaction d'echange. Un point invariant quaternaire est determine dans le systeme...
