Hempseed (Cannabis sativa L.) has been used as a health food and folk medicine in China for centuries. In the present study, we sought to define the underlying mechanism by which the extract of Fructus Cannabis (EFC) protects against memory impairment induced by D-galactose in rats. To accelerate aging and induce memory impairment in rats, D-galactose (400 mg/kg) was injected intraperitoneally ...
This paper describes a novel method to improve drug retention in liposomes for the poorly water-soluble (lipophilic) model drug asulacrine (ASL). ASL was loaded in the aqueous phase of liposomes and the effects of aging conditions and drug loading levels on drug retention were investigated using an in vitro bio-relevant drug release test established in this study. The status of intra-liposomal ...
Investigating the complex systems dynamics of the aging process requires integration of a broad range of cellular processes describing damage and functional decline co-existing with adaptive and protective regulatory mechanisms. We evolve an integrated generic cell network to represent the connectivity of key cellular mechanisms structured into positive and negative feedback loop motifs central...
CONTEXT Higher metabolic rates increase free radical formation, which may accelerate aging and lead to early mortality. OBJECTIVE Our objective was to determine whether higher metabolic rates measured by two different methods predict early natural mortality in humans. DESIGN Nondiabetic healthy Pima Indian volunteers (n = 652) were admitted to an inpatient unit for approximately 7 d as part...
background: aging population and prevalence of diseases like cancer among them have affected general health of the elderly, so that one of the influential factors on health components of elderly patients with cancer is death anxiety, which has important consequences in them. methods: in this cross-sectional (descriptive correlational) study, 130 elderly patients with cancer undergoing chemother...
During operation, the electrical insulation system (EIS) of high-voltage motors is exposed to various factors that can accelerate its aging. Timely knowledge actual state EIS great help in allocating funds for service activities. The condition HV motor be assessed some extent by performing available tests. A major shortcoming lack accuracy and well-defined criteria current standards. In way, a ...
