Relationships between age, dehydro-epiandrosterone sulphate and plasma glucose in healthy men.
BACKGROUND dehydro-epiandrosterone sulphate (DHEAS) has been reported to ameliorate diabetes mellitus in rats. AIM we investigated the relationships between plasma glucose, age, serum DHEAS and weight in healthy men. METHODS we measured the serum DHEAS, fasting plasma glucose, plasma cortisol and body mass index in 169 subjects (mean age 46.5 years). RESULTS there was a significant declin...
متن کاملCorrelation of serum L-carnitine and dehydro-epiandrosterone sulphate levels with age and sex in healthy adults.
OBJECTIVES L-carnitine and dehydro-epiandrosterone (DHEA) independently promote mitochondrial energy metabolism. We therefore wondered if an age-related deficiency of L-carnitine or DHEA may account for the declining energy metabolism associated with age. METHODS we evaluated serum levels of L-carnitine and the sulphated derivative of DHEA (DHEAS) in cross-sectional study of 216 healthy adult...
متن کاملAgeing and vascular ageing.
There is an age related decline in various physiological processes. Vascular ageing is associated with changes in the mechanical and the structural properties of the vascular wall, which leads to the loss of arterial elasticity and reduced arterial compliance. Arterial compliance can be measured by different parameters like pulse wave velocity, augmentation index, and systemic arterial complian...
متن کاملReactivity and structure of the 5-dehydro-m-xylylene anion.
The electronic structure of dehydro-m-xylylene anion (DMX-) has been investigated by using chemical reactivity studies and electronic structure calculations. DMX- has been generated in the gas phase via the sequential reaction of trimethyl-3,5-bis(trimethylsilylmethyl)phenylsilane with F- and two molecules of F2. Reactivity and thermochemical properties of the ion indicate a phenyl-like anion (...
متن کاملHealthy ageing: ageing safely.
The population of the developed world is steadily ageing. In the European Union, approximately 22% of persons are over 60 years of age and this is projected to increase to more than 27% by the year 2020. This has major implications for health care resources and the productive workforce. Ageing is accompanied by a decline in the physiological reserve of all organ systems, compromising homeostasi...
