The oxidative stress theory of aging has brought to the implicit expectation that oxidative stress increases with aging. Unfortunately, a broad investigation in humans is missing due to limitations of conventional oxidative stress status (OSS) analyses. Here we show that the OSS measured in peripheral blood of 247 healthy volunteers, aged 2 days-104 years, using the electron paramagnetic resonance "EPR-radical probe" technique, negatively correlated with age (-1.1 %/year; p < 0.0001) both by simple and multiple linear regression analyses and that it was only marginally affected by sex. These findings stimulate further mechanistic studies.

Abstract
The oxidative stress theory of aging has brought to the implicit expectation that oxidative stress increases with aging. Unfortunately, a broad investigation in humans is missing due to limitations of conventional oxidative stress status (OSS) analyses. Here we show that the OSS measured in peripheral blood of 247 healthy volunteers, aged 2 days-104 years, using the electron paramagnetic resonance "EPR-radical probe" technique, negatively correlated with age (-1.1 %/year; p < 0.0001) both by simple and multiple linear regression analyses and that it was only marginally affected by sex. These findings stimulate further mechanistic studies.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
