Psychosocial factors in healthy ageing
Psychology & Health, 2015While many people will function well and live independently into advanced old age, major acute health events, chronic disease and disability are prevalent in later life.

An overwhelming number of elderly men and women are habitually undernourished. Estimates indicate that one-third to one-half of the health problems of the elderly are a direct or indirect consequence of nutritional deficiencies (Gershell, 1981). People over the age of 60 consume far less than what is believed necessary to meet nutrient standards for ...

Epigenetic factors in aging and longevity
Pflügers Archiv - European Journal of Physiology, 2009Epigenetics refers to phenotypic changes caused by mechanisms that are unrelated to changes in the underlying DNA sequence, most notably chromatin remodeling driven by histone modifications, and DNA methylation. Such variation is transmitted by cell division, but generally not passed on through the germ line.

Although the fundamental mechanisms of in vitro cell aging are still undetermined, certain prominent features have emerged that serve to delineate or focus the search for these mechanisms. In Table 3.1 we present a selected list of changes that accompany senescence in culture.

This chapter, dealing with ageing and its social problems, is the last one in Part III about the individual moving through the time and social dimensions of his life. It deals with the general patterns that come sooner or later to be characteristic of older people, but it stresses that losses and changes in skills do not affect everybody in the same ...

Polyphenol Oxidase as a Factor in Aging
Gerontology, 1977Polyphenol oxidase oxidizes several proteins that contain tyrosine. During aging, when synthesis and replacement of catabolized proteins are lagging, the relative proportion of oxidized species might reach high values, thus impairing physiological function. A mathematical analysis verifies this assumption.
