Astragalus membranaceus ( A. ) is a homologous plant with high medicinal and edible value. Therefore, the extraction methods of polysaccharide (APS) have attracted attention many research groups, but yield active components still not high. The aim this study was to extract APS by semi-bionic method, optimize process, evaluate anti-aging activities in vivo . results showed that 18.23% when extra...

Life expectancy has increased considerably throughout the world. In Bangladesh, life expectancy has increased from about 53 years in 1975 to 69 years in 2010. However, it is unknown whether the increase in life expectancy is simultaneously accompanied by an increase in disability-free life expectancy (DFLE). The purpose of the study described in this article was to explore the relationship betw...

BACKGROUND Gender is one of the most significant factors that influence facial anatomy and behavior, both key factors in the aging process. OBJECTIVE To review male facial anatomy, physiology, and behavior and how it contributes to sexual dimorphism in facial aging. METHODS A MEDLINE search was performed for publications on gender differences in facial anatomy, aging, cutaneous physiology, ...

Thyroid function decreases and cold exposure response becomes impaired with increasing age. We investigated the age-related changes in thyroid structure and function and cold-induced changes in the thyroid activity of aging rats. Thirty-two male Sprague-Dawley rats were randomly divided into four groups (8 rats per group): young (7 months) and old (22 months) groups exposed to room temperature ...

Running Title: Age-dependent regulation of TRPV5 and TRPV6 Abstract Aging is associated with alterations in Ca 2+ homeostasis, which predisposes elder people to hyperparathyroidism and osteoporosis. Intestinal Ca 2+ absorption decreases with aging and in particular active transport of Ca 2+ by the duodenum. In addition, there are age-related changes in renal Ca 2+ handling. To examine age-relat...

Methods of rapidly and accurately assessing the chemical stability of pharmaceutical dosage forms are reviewed with respect to the major degradation mechanisms generally observed in pharmaceutical development. Methods are discussed, with the appropriate caveats, for accelerated aging of liquid and solid dosage forms, including small and large molecule active pharmaceutical ingredients. In parti...

Taking as a starting point the verse 356 of satire X by Juvenal –mens sana in corpore sano- and analysis study of its misinterpretation, is described in detail as one proper elements model of active aging, physical activity practiced by elderly, it was present writings of several notable people Ancient Rome. Through exegesis literary sources, we see that there relation between Ancient ...

Skeletal muscle performance declines with advancing age, and the underlying mechanism is not completely understood. A large body of convincing evidence has demonstrated a crucial role for interstitial K+ concentration ([K+]o) in modulating contractile function of skeletal muscle. The present study tested the hypothesis that during muscle contraction there is a greater accumulation of [K+]o in a...
