Hydroxyapatite of approximately stoichiometric composition (Ca/P molar ratio 1.65) evacuated at 600Β°C and exposed to 0, at room temperature produces ESR spectra with g,, = 2.0013, gV, = 2.0102 and g:, = 2.0160, providing evidence for the formation of 0;. Although the ESR signal attributed to Fs+ cen

Guanine conversion to 8-oxyguanine (OG) was induced by irradiation and oxygen radicals. The pathways of mutations caused by such DNA damage have been considered. Minima of interaction energies of OG with nucleic acid bases are revealed via classical potential function calculations. The minima exist
