mitochondrial function was measured in aged dogs and revealed that antioxidant fortified food reduced age-associated mitochondrial dysfunction by reducing ROS production.
these results suggest that one mechanism by which the antioxidant fortified food improved cognition was by maintaining mitochondrial homeostasis by either the antioxidant fortification or the mitochondrial nutrient (L-carnitine,lipoic acid) targeted fortification.
oxidative damage to proteins from the parietal cortex was measured by derivatization with 2,4-dinitrophenylhydrazine (DNPH)which revealed reduced damage in dogs fed antioxidant fortified food.
