Mechanisms of Biologic Aging

Dermatologic Clinics, 1986
The authors outline the progression of thought on the mechanism of the aging process, giving emphasis to environmental factors that influence genetic events. Discussion is limited to those theories that explain fundamental causes of aging and have a firm thermodynamic basis.

Aging: Biologic or Pathologic?

Hospital Practice, 1978
If disease is only case casually related to aging, the prevailing strategy of dealing with each disease category is appropriate; if they are linked causally, the current strategy may not only be inappropriate but prove futile. The extent to which optimal gerontologic care can delay the onset of biologic deterioration, together with the use of short ...

Reappraisal of Biological Ageing

Nature, 1970
LIVING systems depend on adaptive regulation, deterioration in which leads eventually to death. The incidence of most disease increases with increasing age, which suggests that progressive impairment of adaptive response is associated with many illnesses common to advanced age. One biochemical expression of this impairment is the age-dependent increase

The propensity of biological aging

Archives of Gerontology and Geriatrics, 1984
From birth to death life represents a structural connection of events, regardless of the space of time separating them. The potentiality of a living system is a finite one. It can only be finite since infinity cannot be achieved by a progression of finite elements.

On the ontology of biological aging

Archives of Gerontology and Geriatrics, 1988
The central question in the field of experimental gerontology is: what is biological aging? It is true that a living body must obey the laws of causal determinism; like all bodies it is subject to the physical and chemical laws of the phenomenal world.

Biological anthropology and aging

Journal of Cross-Cultural Gerontology, 2005
As the number of persons aged 65 and older is increasing dramatically in both developed and developing nations of the world, the health and well-being of elders has become a worldwide public health concern. Although older adults are now found in higher proportions across all cultures, the biology, behavior, and environment vary tremendously across ...

Current Theories of Biological Aging

The Gerontologist, 1974
Several lines of evidence have led to the notion that biological aging occurs as a result of changes in the information-containing molecules either at the genetic or epigenetic level. The error theory, the redundant message theory, the codon restriction theory, and the transcriptional event theory represent the major current conceptualizations of ...

Biological Aging

JAMA, 1974
AGING satisfies the major criterion of a normal physiologic process; it descends inexorably on each and every one of us. Whether this kind of normality is desirable is a debatable point. Teleological approaches are largely unsatisfactory because the nth stage of improved survival is immortality, which implies detrimental effects for the species in ...
