Interactions of thiyl free radicals with oxygen: a pulse radiolysis study.
A pulse radiolysis study of glutathione in aqueous solution at pH 5.5 containing N2O/O2 mixtures at various ratios indicates that oxygen rapidly adds to the thiyl glutathione radical yielding aExpand

The inactivation of alcohol dehydrogenase by x-rays and the dose-modifying effect of some added substances.
The inactivation yield of yeast alcohol dehydrogenase in 0.05 M phosphate buffer, pH 7, was found to be 0.14 molecule per 100 eV. The apparent yield was constant in the range 0.1 to 1 mg/ml, showingExpand

Primary and secondary radicals in the radiation-induced inactivation of yeast alcoholdehydrogenase.
SummaryRadiation inactivation of YADH in dilute aqueous solution that does not contain oxygen is due to H atoms and OH radicals, whose inactivating efficiencies are in the ratio 9 : 1. The sameExpand

FURTHER OBSERVATIONS ON IN VITRO RADIOSENSITIZATION OF RABBIT ERYTHROCYTES BY IODOACETIC ACID AND RELATED SUBSTANCES.
SummaryA number of compounds more or less related to iodoacetic acid (IAA) have been tested for their radiosensitizing effect on rabbit erythrocytes.As reported previously, red cells irradiated inExpand
