Ageing is a nonmodifiable risk factor that is linked to increased likelihood of cardiovascular morbidities. Whilst many pharmacological interventions currently exist to treat many of these disorders such as statins for hypercholesterolemia or beta-blockers for hypertension, the elderly appear to present a greater likelihood of suffering non-related side effects such as increased risk of develop...

The effects of chronic sun exposure on skin are readily apparent when skin not typically exposed to the sun and skin regularly exposed to the sun are compared. While the sun is not the only aetiological factor in the dynamic process of skin ageing, it is the primary exogenous cause among several internal and environmental elements. Thus, photo-ageing, the main focus of this article, is a subset...

Abstract Many industrial applications require natural rubber (NR) as an irreplaceable polymer for its unique behaviour resistance to crack growth. The damage caused by ozone, seen ageing accelerator, influences the lifetime of components. data on ozone-induced experiments are often incomplete or remain unpublished, whereas comprehensive databases other environmental loads oxygen do exist. A var...

The paper aims to examine the population ageing as a new phenomenon effecting rural areas in Iran. Population ageing is going up throughout the country especially in the rural areas by 6.8 percent. fertility decline, increase in the youth migration to cities, and coming back to rural areas after retiring are the major factors which involve in rural ageing. This may jeopardize the communities. f...

introduction: elder abuse may increase the vulnerability of ageing people to disease and decrease their general health status, so addressing the issue is essential for promoting elderly quality of life. the study aimed to examine the relation between abuse experience and general health among elderly people in yazd city- iran. methods: the cross-sectional study carried out on 250 community-dwell...

Triacetone triperoxide (3,3,6,6,9,9-hexamethyl-1,2,4,5,7,8-hexoxonane; TATP) is one of the most frequently used improvised explosives, often misused worldwide. In our previous studies, we had observed that the kind of acid used to catalyse its formation has a significant influence on TATP’s properties. TATP was prepared using five different acids that are often used in improvised conditions. Al...

Accumulated evidence from epidemiological, clinical, and laboratory studies have supported the important role of estrogens on skin physiology. Estrogen therapy has been demonstrated as a therapy for the signs of ageing related to estrogen deficiency in menopausal women. Unlike cosmetic products, estrogens cannot be used as therapy for skin-ageing in all women due to their potencies and ability ...

Problem: Genetic and demographic studies suggest that ageing is an adaptive genetic program, but population genetic analysis indicates that the benefit of ageing to the group is too slow and too diffuse to offset its individual cost. Premise: Demographic homeostasis is a major target of natural selection at the group level, with a strength that can compete with the imperative to higher individu...
