This book describes mechanisms of skin damage generation and examines the potential impact of free radicals, reactive oxygen species (ROS) and oxidative damage on the skin ageing process. It also evaluates methods to decrease skin oxidative stress, oxidative damage, and skin ageing. The identification of free radical reactions as promoters of the skin ageing process implies that interventions aimed at limiting or inhibiting free radical reacti...

Oxidative stress, which is caused by endogenous and exogenous reactive-oxygen-species (ROS) formation, may significantly affect health-span and longevity. Endogenous oxidative stress could be attenuated in two ways: by the reduction of ROS formation and by quenching ROS with antioxidants. Numerous results of clinical trials in which individuals received one or more synthetic antioxidants failed to demonstrate conclusive benefits of antioxidant...

Ageing is an inevitable biological process that affects most living organisms. The link between metabolic rate and reactive oxygen species production is an important and long-standing question, and a source of much controversy. A by-product of cell respiration in mitochondria is the formation of reactive oxygen species due to electron leakage from the electron transport chain during oxidative phosphorylation. In simple terms, humans are ageing...

The book offers a comprehensive review of current research regarding the influences of environmental factors involved in human health and ageing. Many environmental compounds promote excessive oxidative stress, which is the primary cause of accelerated ageing and which also contributes to the development of human diseases. The basic concepts of ageing theories are discussed, as is the promotion of oxidative stress which has been identified as ...
