Abstract Both Sn addition and pre-ageing are known to be effective in maintaining the artificial ageing potential after natural of Al–Mg–Si alloys. In this study, combined effects at 100 °C or 180 on secondary subsequent an alloy AA6014 were investigated using hardness, electrical resistivity, differential scanning calorimetry transmission electron microscopy characterizations. It is found that...

increasing of the aging population in most of the developed countries should be more attention to the health issues of this aged group. in iran, the ageing program has been launched and some institutes or organizations have been in charge of this program. the coordination of health policies and activities in elderly care programs and ageing networks could be helped to improve of elderly life sp...

in the present work, the influence of aging temperature on mechanical properties and sound velocity of maraging steel m350 was investigated. for this purpose, first, samples were solution annealed at 825◦c for 2 hours and then age hardened at 510◦c-600◦c for 3 hours. hardness, tensile and impact tests were used for determining mechanical properties and longitudinal ultrasonic velocity was used ...

OBJECTIVE The need for effective 'anti-ageing' treatments, in particular for the management of photodamaged skin, prompted us to develop a novel method to identify new active ingredients. The model utilized a gene profiling study with corresponding connectivity mapping (Cmap) to identify novel anti-ageing compounds using all-trans retinoic acid (RA) as the lead compound due to its beneficial ef...

Ageing is characterized by the expansion and the decreased vascularization of visceral adipose tissue (vAT), disruption of metabolic activities, and decline of the function of the immune system, leading to chronic inflammatory states. We previously demonstrated that, in vAT of mice at early state of ageing, adipocytes mount a stress resistance response consisting in the upregulation of ATGL, wh...

background: increased life expectancy and the growing phenomenon of aging can lead to increased burden of chronic diseases (cds) which adversely affects the overall health of elderly, their sexuality in particular. sexual life of aged population is overlooked in many of the societies. in the present narrative review, we aim to assess the impact of cds on sexual function of elderly people. mater...

introduction: motor skills play an important role during life span, and older adults need to learn or relearn these skills. the purpose of this study was to investigate how aging affects induction of improved movement performance by motor training. methods: serial reaction time test (srtt) was used to assess movement performance during 8 blocks of motor training. participants were tested in two...

Ageing induces seed deterioration expressed as the loss of seed vigor and/or viability. Priming treatment, which consists in soaking of seeds in a solution of low water potential, has been shown to reinvigorate aged seeds. An experiment was conducted to evaluate the effects of naturally and accelerated aging on seed germination traits and enzyme activities (proxidase, catalase and superoxid dis...

Abstract Ageing is often accompanied with a decline in immune system function, resulting ageing. Numerous studies have focussed on the changes different lymphocyte subsets diseases and immunosenescence. The change phenotype key indication of diseased or healthy status. However, number brought about by ageing not been comprehensively analysed. Here, we analysed T natural killer (NK) cell subsets...
