We show that a Gaussian-shaped pulse can be used to excite selected 1H signals in hydroxyapatite, monetite and H-Y zeolite loaded with trimethylphosphine oxide (TMPO). This selective excitation method can be incorporated into Lee-Goldburg (LG) cross-polarization to obtain useful spectral...

Spin trapping using 5,5-dimethyl-1-pyrroline N-oxide (DMPO) has been used to detect and distinguish between the carbon-centred, alkoxyl, and peroxyl radicals produced during the photolytic decomposition of hydroperoxides. Photolysis of tert-butyl and cumene hydroperoxides, and peroxidized fatty acids, in toluene, with...

The hydroxyl radical adducts of 5,5 dimethyl-1-pyrolline-N-oxide (DMPO) and 3,3,5,5 tetramethyl-1-pyrolline-N-oxide (TMPO) formed in the presence of hydrogen peroxide and FeII are normally quite stable, but in the presence of 5-20 micromolar myoglobin their ESR signals decay rapidly. This decay...

The roles of oxygen and reactive oxygen intermediates in apoptosis are unclear at present. Although oxygen and reactive oxygen intermediates are not required for the execution of apoptosis, oxygen may be involved in at least some forms of apoptosis. In...

A new approach for in vivo spin trapping and quantitation of oxygen-derived free radicals has been developed using a continuous flow high speed ESR detection system. Spin adducts of OH. were detected as 1:1:1:1:1:1 sextets (aN=15.2 G, aH=16.8 G, g=2.0055)...
