Ageing, physical function, and the diurnal rhythms of cortisol and dehydroepiandrosterone.
The present study examined the relationship between ageing, physical function and the diurnal rhythms of cortisol and dehydroepiandrosterone (DHEA). Participants were 36 community dwelling older adults aged between 65 and 86 years old. Salivary cortisol and DHEA were measured over the course of one day: immediately upon awakening, 30 min later, and then 3 h, 6 h, 9 h and 12 h post-awakening. Pa...
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 کاملDHEA: dehydroepiandrosterone.
Dehydroepiandrosterone (DHEA) and its active metabolite, DHEA sulfate (DHEAS), are endogenous hormones synthesized and excreted primarily by the zona reticularis of the adrenal cortex in response to adrenocorticotropic hormone. The exact mechanism of action and clinical role, if any, of DHEA and DHEAS remain unclear. Epidemiological data indicate an inverse relationship between serum DHEA and D...
متن کاملDehydroepiandrosterone (DHEA) and dehydroepiandrosterone-sulfate (DHEAS) and emotional processing — A behavioral and electrophysiological approach
Dehydroepiandrosterone (DHEA) and dehydroepiandrosterone-sulfate (DHEAS) may have mood enhancement effects: higher DHEAS concentrations and DHEA/cortisol ratio have been related to lower depression scores and controlled trials of DHEA administration have reported significant antidepressant effects. The balance between DHEAS and DHEA has been suggested to influence brain functioning. We explored...
متن کاملSerum levels of dehydroepiandrosterone and dehydroepiandrosterone sulfate and the risk of developing gastric cancer.
Although the incidence of gastric cancer varies widely between countries it is nonetheless a leading cause of cancer deaths worldwide. Migration studies indicate that dietary choices are an important exogenous factor. The United States has a very low incidence of gastric cancer, suggesting that exogenous etiological agents are at a minimum and providing a favorable setting for detecting importa...
