(author), Centraal Instituut voor Voedingsonderzoek TNO TNO Voeding (author)Coenzyme Q10 (CoQ10) is an important mitochondrial electron transfer component and has been postulated to function as a powerful antioxidant protecting LDL from oxidative damage. It could thus reduce the risk of cardiovascular disease. Thus far, beneficial effects of supplementation with CoQ10 have been reported. To study the relation between...article 1999

(author), Centraal Instituut voor Voedingsonderzoek TNO TNO Voeding (author)Background: Response to cisplatin-therapy is assumed to be related to the formation of platinum (Pt)-DNA adducts. Measurement of these adducts prior to therapy could be of value to improve cisplatin based cancer therapy. Materials and methods: We determined Pt-GG and Pt-AG adduct levels by use of 32P-postlabeling after ex vivo cisplatin...article 1999
