Waste Accumulation Theory
The waste accumulation theory of aging says that in the course of a life period cells produce more waste than they can properly eliminate. The waste materials includes various toxins that after accumulated to some certain level they can interfere with normal cellular function and ultimately kill the cell.
Small group of Cellular Divisions Theory
This theory is concerned with the number of cellular divisions directly affected by the actual accumulations of the cell�s waster products. As more wastes accumulate over time the cells quickly degenerate thus causing aging and ultimately dying.
Hayflick Limit Theory
Dr. Hayflick theorized that the aging process was controlled with a biological time clock contained within each living cell. Studies completed in 1961 concluded that human fibroblast tissue (lung, skin, muscle, heart) have a limited life time. They separate approximately Fifty times over a period of years and then suddenly stop. They also came to the conclusion nutrition seemed to have an effect on the rate of cellular division. Final conclusion of this theory says that incorrect functioning associated with cells as well as loss of tissue in internal organs and tissues may be responsible for the effects of aging.
Death Hormone Theory (DECO)
Brain cells or neurons tend to be unlike additional cells for the reason that they do not duplicate. At birth we have roughly 12 billion of them and also over a life time regarding 10 percent pass away out. Doctor. Donner Denckle speculated which as we age the actual pituitary begins to launch DECO which inhibits the ability of cells to use thyroxine. Thyrozine is really a hormone made by the thyroid-governing basal metabolism, which is the price at which cells convert food to power. The metabolic rate brings on as well as accelerates the process of aging.
Dr. Mike Goldstein says �the thymus is the master human gland of the natureal defenses.� The size of the actual gland is constantly on the reduce and shrink in order to round three grams by age Sixty. Scientists are investigating the possibility that the disappearance from the thymus contributes to the aging process by deterioration the body�s immune system.
This is actually the free radical theory is supported by directed experimental observations associated with Mitochondrial aging. Our primary source of energy comes from ATP. Mitochondria are the energy-producing organelles in the cells which produce ATP. They create cell power by a procedure that leads to forming potentially damaging free radicals. Proof seems to inform us that various kinds of accumulated Genetic make-up damage with time contribute to illness. New study in mitochondrial restore could perform an important role in the fight against getting older.
Errors and Repairs Theory
Dr. Leslie Orgel recommended in 1970 that because the �machinery for making proteins in tissue is so essential, an error in that machinery might be catastrophic.� Since the system is incapable of always making perfect repairs on these molecules, the accumulation associated with flawed molecules can cause illness and other age changes to happen.
Redundant DNA Theory
This particular theory is comparable to the error-and-repairs concept in that it also blames mistakes accumulating in genes for age changes. A difference is that as these errors accumulate the reserve hereditary sequences of identical DNA that take over until the system is work out.
