“…The overall ROS production increases, while the overall efficiency of the antioxidant defense systems decreases during aging (Ames et al, 1993;Martin et al, 1996;Reiter et al, 1995;Shigenaga et al, 1994), with a clear organ-specificity (Sohal et al, 1995;Tian et al, 1998). These are factors determining 8-OHdG levels at a particular age in a particular organ, and the other factors include the status of repair mechanisms, oxygen exposure, metabolic and oxygen consumption rates, and cell proliferation activity (Ames et al, 1993;Fraga et al, 1990).…”

“…Hayakawa et al (1991 and1992) also reported an aging-dependent accumulation of 8-OHdG and mutations of mitochondrial DNA of human heart and diaphragm tissues. However, oxidative damage of cellular protein increases with age in the brain and liver of rats (Tian et al, 1998). In contrast, while the extent of lipid peroxidation in the brain or liver of rats is not altered by aging (Lopez-Torres et al, 1992;Tian et al, 1998), its byproducts can react with DNA to form dG malondialdehyde adducts, of which frequency increases in the liver and kidney but not in the testis with age in rats (Draper et al, 1995).…”

“…The use of melatonin to slow down the progression of undesirable age-related events is also supported by reports that either melatonin treatment or pineal grafting can retard the thymic involution that characterizes aging [33,67]. It may be that aging is fundamentally an event programmed by the pineal gland [68].…”

“…Impaired respiratory function may lead to oxidative stress and also to impairment of antioxidant enzyme systems [33]. Decline of mitochondrial functioning has also been associated with various age-related neurodegenerative diseases including Alzheimer's, Parkinson's, and Huntington's diseases and amyotrophic lateral sclerosis [34].…”

“…Πράγματι, σε μία εργασία τα πρωτεϊνικά καρβονύλια αυξήθηκαν μετά την άσκηση στο αίμα και τους ιστούς επιμύων ενώ πτώση της GSH παρατηρήθηκε στο πλάσμα, το ήπαρ, τον νεφρό και το σκελετικό μυ επιμύων (Leeuwenburgh & Ji, 1995). Σε άλλη εργασία, τα πρωτεϊνικά καρβονύλια στο ήπαρ και τον εγκέφαλο ήταν αυξημένα σε επίμυες ηλικία 24 μηνών σε σύγκριση με νεαρότερους επίμυες ηλικίας 6 μηνών (Tian et al, 1998). Επιπρόσθετα, μία σχετιζόμενη με την ηλικία αύξηση της MDA, των πρωτεϊνικών καρβονυλίων και της GSSG παρατηρήθηκε στα μιτοχόνδρια του εγκεφάλου και του καρδιακού μυός επιμύων (Cocco et al, 2005).…”
