Oxidative modification of proteins: age-related changes.

abstract：BACKGROUND:Hearing impairment (HI) is a very common condition in elderly people and the epidemiology together with hearing-related problems is still poorly investigated. Moreover, the cognitive status may be impaired in relation to hearing function. OBJECTIVE:The goal of the study was to evaluate: (a) the prevalence o...
