Textbooks and policy documents tend to present the boundary between normal and abnormal ageing as natural and clearly demarcated. In this study, we trouble the notion of natural and clearly demarcated boundaries between normal and abnormal ageing by considering how these boundaries have been established and maintained in present-day Western contexts. We draw on both Canguilhem's discussion of t...

OBJECTIVE to identify perceptions of, and associations with, active ageing among ethnically diverse and homogeneous samples of older people in Britain. DESIGN AND SETTING cross-sectional and longitudinal surveys of older people living at home in Britain. MEASURES active ageing, health, psych-social, socio-economic circumstances, and indicators of quality of life. RESULTS respondents defin...

The Human Ageing Genomic Resources (HAGR) is a collection of online resources for studying the biology of human ageing. HAGR features two main databases: GenAge and AnAge. GenAge is a curated database of genes related to human ageing. Entries were primarily selected based on genetic perturbations in animal models and human diseases as well as an extensive literature review. Each entry includes ...

Design and setting: cross-sectional and longitudinal surveys of older people living at home in Britain. Measures: active ageing, health, psych-social, socio-economic circumstances, and indicators of quality of life. Results: respondents defined...

INTRODUCTION In the context of an increasingly ageing society with a growing number of persons diagnosed with chronic disabling conditions including dementia and persons with disabilities, ageing and disability represent two policy fields which need to be jointly re-thought. So far, policymakers and other political actors have not adequately reacted to these changing demographics. DESCRIPTION...

This article investigates the extent to which the emerging trend of do-it-yourself anti-ageing skin-whitening products represents a re-articulation of Western colonial concerns with environmental pollution and racial degeneracy into concern with gendered vulnerability. This emerging market is a multibillion dollar industry anchored in the USA, but expanding globally. Do-it-yourself anti-ageing ...

Human ageing is a fundamental biological process that leads to functional decay, increased risk for various diseases and, ultimately, death. Some of the basic biological mechanisms underlying human ageing are shared with other organisms; thus, animal models have been invaluable in providing key mechanistic and molecular insights into the common bases of biological ageing. In this Review, we bri...

Skin ageing is a complex process that is determined by both intrinsic and extrinsic factors, which leads to a progressive loss of structure and function. There is extensive evidence indicating that oxidative stress induced by reactive oxygen species plays an important role in the process of human skin ageing. Mitochondria are the major source of cellular oxidative stress and are widely implicat...

The ageing of asphalt mixes, together with their exposure to low temperatures, causes a progressive increase of cracking. In this paper, the effect of ageing and temperature on the fatigue of asphalt concretes made with two types of binders, conventional (50/70) and polymer modified bitumen (PMB), is studied. For this purpose, specimens previously subjected to an accelerated laboratory ageing p...

The factors necessary to obtain an optimal heat treatment that influence the hardness and resistivity of Al-6Si-0.5Mg casting alloys with Cu or/and Ni additions were investigated. The alloys were homogenised (24hr at 500C), solutionized (2hr at 540C) and artificially ageing at various times and temperatures. The alloys were aged isochronally for 60 minutes at temperatures up to 400C and isother...
