In this study, PP films were modified with an organic pro-degradant in different concentrations (1, 2 and 3 wt.%), exposed in the first step of degradation to natural ageing for 100 days followed by biodegradation in simulated soil in the respirometric test for 100 days. At the end of the combined degradation process the PP samples were characterized according to their morphological and physica...

apparent rise in the incidence of infertility in females and the trend shifting towards delayed child bearing brought up the concept of ovarian ageing. women in their early thirties show poor ovarian reserve which is an entity named as early ovarian ageing. early ovarian ageing is mostly genetically determined, but acquired modifiable factors like smoking, or ovarian surgery have some roles. in...

The present study concerns the relation of mental and bodily characteristics to one another during ageing. The 'common cause' theory of ageing proposes that declines are shared across multiple, seemingly-disparate functions, including both physical and intellectual abilities. The concept of 'reserve' suggests that healthier cognitive (and perhaps bodily) functions from early in life are protect...

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...

In response to the expressed need for more sophisticated and multidisciplinary data concerning ageing of the Australian population, the Australian Longitudinal Study of Ageing (ALSA) was established some two decades ago in Adelaide, South Australia. At Baseline in 1992, 2087 participants living in the community or in residential care (ranging in age from 65 to 103 years) were interviewed in the...

Interest has arisen during the last 10 years as to the possible connection between the age-related decline in androgen production and symptoms of ageing in men. A new ageing-related syndrome with several descriptive names, such as andropause, male menopause, Partial Androgen Deficiency of the Ageing Male (PADAM) and Late-Onset Hypogonadism (LOH), has been identified. Intensive research into the...

Skin ageing has intrinsic signs and symptoms, often complicated by extrinsic photo-ageing symptoms and concurrent disease processes. It progresses with age but varies between individuals and its symptoms are numerous. Skin ageing has physical and psychosocial repercussions that can influence coping. Emollient therapy can help to reduce two symptoms--dryness and loss of the skin's barrier functi...

A comprehensive definition of successful ageing would combine the elements of survival (longevity), health (lack of disability), and life satisfaction (happiness). Predictors of longevity include being female, being physically active, not smoking, having good cognitive functioning, higher socio-economic status and greater life satisfaction. Predictors of life satisfaction include being healthy ...
