Objectives Dominant views of aging generate anxiety for many adults-especially women, who face greater disadvantages in later life compared with men. However, little is known about changes in these concerns over time and their variation across women. Employing a feminist perspective on age relations, our study examines three social contexts affecting women's aging anxiety-social location, healt...

Aging phenomena have been studied in very different materials like polymers, supercooled liquids or disordered orientational crystals. We recall here the main features of aging in spin glasses, and use this example of magnetic systems as a guideline for the description of the others. A particular attention is put on the sensitivity of aging to the cooling rate and to temperature variations. Thi...

Aging is a time-dependent decline in physiological function that affects most organisms and the major risk factor for many non-communicable diseases. The early diagnosis of aging critical treatment aging-related In recent years, extensive efforts have attempted to accurately diagnose aging. To date, multiple types fluorescent probes various age-related biomarkers been developed, with aims achie...

As we know sol-gel is one of the most important techniques for thin film preparation. In this paper, high transmission silica thin films have been prepared by dip-coating process from a new silicon-alkoxide solution. The prepared sol was stable for 45 days which is very important to characterize the coating process. The optical properties as a function of aging time, withdrawal rate, and he...

background: aging contains morphological and functional deterioration in biological systems. d-galactose (d-gal) generates free radicals and accelerates aging. portulaca oleracea (purslane) may have protective effect against oxidative stress. objective: purslane ethanolic extract effects were evaluated on antioxidant indices and sex hormone in d-gal aging female mice. materials and methods: 48 ...

The present study examined time-related change in felt age, physical age, and satisfaction with aging in old age and covariates of this change. Using 6-year-longitudinal data from the Berlin Aging Study (age range = 70-104 years), we found that individuals' felt age remained on average about 13 years below their actual age over time, whereas they reported a decreasing discrepancy between physic...

In this paper, accelerated multi-factor aging tests in laboratory have been conducted on the stator ham of a large generator. During the period of aging, the temperature spectra of dielectric dissipation factor tan 6 of stator insulation were employed to investigate aging characteristics of insulation materials. Test results showed that the peak temperature T,,, of the tan 6 -T curve under 0.2U...

objective(s): in the current study, the effects of selected folk medicinal herbs were evaluated in d-galactose-induced aging in male mice.   materials and methods: male balb/c mice were randomly divided into 12 groups composing sham, control, and treated groups. aging was induced by administration of d-galactose (500 mg/kg/day for 6 weeks). a positive control group was assigned that received vi...
