Frailty and biological age. Which best describes our aging and longevity?
Molecular Aspects of MedicineThis work was supported by the Research Group of Complutense University of Madrid (910379).Frailty and Biological Age are two closely related concepts; however, frailty is a multisystem geriatric syndrome that applies to elderly subjects, whereas ...

Chronological and biological age
Experimental Gerontology, 1984Resuming the thread of previous studies, this paper reports a new method of assessing biological age with the inclusion of physical, psychical, and social parameters. The suitability of the method was tested on a total of three hundred and sixty-five subjects.

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 ...
