Paper Summary:
This paper analyzes the aging process in humans. It describes the effect of aging on the organs of the body and discusses the role of reactive oxygen species (or ROS), which includes oxygen free radicals (or OFRs) in this process. The paper also discusses chronic fatigue and its effects and then briefly discusses the link between fatigue and aging.
From the Paper:
"Fatigue and aging seem linked. A decrease in energy production with aging is associated at least partly with mitochondrial lipid peroxidation by ROS and the body's failure to replace or repair the injured molecules. Damage to the membranes and the consequent dysfunction of mitochondria by ROS can also lead to certain changes, such as mutations and deletions in the mitochondrial DNA or mtDNA. The mitochondrial theory of aging suggests that degenerative disease is explained partly by accumulated mtDNA mutations and deletions and oxidative injury to mitochondrial members through time. These findings connected chronic diseases to the degree of mitochondrial membrane lipid peroxidation and mtDNA injury. This is why experts link or relate the damage of mtDNA and mitochondrial membrane age-related degenerative diseases. These diseases lead to important cell changes, which determine its survival and say a lot about the disturbing phenomenon known as aging (Nicolson)."
