The oxidative environment and protein damage
WebbBackground: Advanced oxidation protein products (AOPP) are newly identified efficient oxidative stress biomarkers. In a longitudinal birth cohort the effects were investigated of genetic polymorphisms in five oxidative pathway genes on AOPP levels. Methods: This study is part of a three-arm randomized, double-blind, placebo-controlled trial.
