objectives: the main purpose of this study was to determine the interactive role of physical activity and personality traits inpsychosocial development of elders. methods & materials: this research was a casual comparative with 300 elders (150 active and 150 non-actives) with 60-85 years old from tehran selected as statistical sample on available bases. all subjects completed psychosocial devel...

age related cytochemical changes of thymic endocrine cells were studied in 78 day old chicks at five day interval to age of day 60 employing a panel of cytochemical stains. methenamine silver revealed cell morphology including cell processes distinctly while diamine silver revealed a stronger argentaffinity in these cells. the cells had greater affinity for diamine silver compared to methenamin...

the effects of zinc oxide (zno) and e. coli-derived 6-phytase supplemented-diet on the reproductive performance in aged broiler breeder hens and on immune responses of their progeny chicks were studied. in a 2×4 factorial arrangement, 2 inclusion levels (0 or 300 u kg-1 diet) of e. coli-derived phytase and 4 inclusion levels (30, 60, 90, and 120 mg kg-1 diet) of zno were provided from 62 throug...

introduction: elderly patients suffer disproportionally from a number of chronically painful conditions, with arthritis leading the list. osteoarthritis (oa) is the most common joint disorder and the most prevalent cause of joint pain across the spectrum of middle age to elderly. enhancing behavioral intention toward self-care for oa, previously known as proximal predictor of self-care, is one ...

conclusions based on the results of the present study and other performed studies in this regard, menopause, aging, vasomotor symptoms, and education had significant association with the qol of postmenopausal women. the reduced qol in postmenopausal women could eventually lead to the reduced qol of their spouses. therefore, it is necessary to plan for the education of these women and their husb...

objective(s):some pathologic situations such as diabetes and metabolic syndrome are associated with alternation in nitric oxide level. incidence of these condition increases with aging. on the other hand, insulin secretion is modulated by nitric oxide, and nitric oxide synthase (nos) activity is also altered in diabetes. in this study, modification in the enzyme activity associated with aging a...

The omnipresence of chromophoric dissolved organic matter (CDOM) in the open ocean enables its use as a tracer for biochemical processes throughout the global overturning circulation. We made an inventory of CDOM optical properties, ideal water age (τ), and apparent oxygen utilization (AOU) along the Atlantic, Indian, and Pacific Ocean waters sampled during the Malaspina 2010 expedition. A wate...

Vascular aging plays an important role in the mortality of the elderly, but vascular aging can be dependent on other factors such as diseases. Various diseases such as Alzheimer, diabetes, thalassemia, and other diseases affect the mechanisms of vascular aging. It will harm the recovery process of these patients. There are methods for measuring vascular aging such as instrumental measurements a...

The influence of normal aging in early, intermediate and high-level visual processing is still poorly understood. We have addressed this important issue in a large cohort of 653 subjects divided into five distinct age groups, [20;30[, [30;40[, [40;50[, [50;60[and [60;[. We applied a broad range of psychophysical tests, testing distinct levels of the visual hierarchy, from local processing to gl...
