For a person on dialysis, fluid is usually restricted or limited. One job of healthy kidneys is to remove excess fluid from the body. When your kidneys are not working properly, dialysis can remove some of the fluid, but you will also need to drink or eat less fluid. Having âtoo muchâ fluid can cause problems, some of which are serious.
Mitochondrial theory of aging, a variant of free radical theory of aging, proposes that accumulation of damage to mitochondria and mitochondrial DNA (mtDNA) leads to aging of humans and animals.itochondrial theory of aging matures--roles of mtDNA mutation and oxidative stress in human aging.

Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Although most DNA is packaged in chromosomes within the nucleus, mitochondria also have a small amount of their own DNA.This genetic material is known as mitochondrial DNA or mtDNA.In humans, mitochondrial DNA spans about 16,500 DNA building blocks (base pairs), representing a small fraction of the total DNA in cells. Mitochondrial DNA contains 37 genes, all of which are essential for normal mitochondrial function.utations in the MT-CYB gene found in mitochondrial DNA can cause mitochondrial complex III deficiency. When caused by mutations in this gene, the condition is usually characterized by muscle weakness (myopathy) and pain, especially during exercise (exercise intolerance).
