Phototherapy in the Age of Biologics
Seminars in Cutaneous Medicine and Surgery, 2011Dermatologists are presented with a diversity of therapeutic modalities for the treatment of inflammatory, sclerosing, and neoplastic conditions, but with the development of various new irradiation devices that utilize specific parts of the electromagnetic spectrum, phototherapy has become a more viable, accessible, and efficacious option in the ...

The measurement of biological age
Experimental Aging Research, 1980One of the objectives of gerontological research is to achieve, reproducibly and at will, a verifiable discrepancy between the chronological and biological age of organisms. To accomplish this, the experimenter must be in a position to measure biological age independently.

Biological Boundaries and Biological Age
Acta Biotheoretica, 2009The chronologic age classically used in demography is often unable to give useful information about which exact stage in development or aging processes has reached an organism. Hence, we propose here to explain in some applications for what reason the chronologic age fails in explaining totally the observed state of an organism, which leads to propose ...

Human Development, 2009
Aging in mammals appears to be an information loss, probably at the cellular or molecular level. The current models for this process and the prospects for its controllability are reviewed. Stochastic, developmental, clonal and immunological models of aging, which are not mutually exclusive, all offer possibilities for rate-modification in Man, with ...

Redundancy and Biological Aging
Science, 1963The relationship between aging and organizational redundancy in biological systems was investigated from the standpoint of information theory. A mortality rate function derived for a randomly deteriorating redundant system approximates observed mortality rates more closely than does the Gompertz function and indicates that variations in redundancy ...

Reappraisal of Biological Ageing
Nature, 1970LIVING 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

Aging: Biologic or Pathologic?
Hospital Practice, 1978If 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 ...

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.

On the ontology of biological aging
Archives of Gerontology and Geriatrics, 1988The 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.

The propensity of biological aging
Archives of Gerontology and Geriatrics, 1984From 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.
