Metabolism of dehydroepiandrosterone and dehydroepiandrosterone sulfate in tissue extracts of rabbit ovaries [PDF]

Steroids, 1969
Abstract The simultaneous incubation of 3H-dehydroepiandrosterone sulfate and 14C-dehydroepiandrosterone by soluble and microsomal extracts of rabbit ovaries was investigated. 3H-dehydroepiandrosterone sulfate was converted to 3H-androstenediol-3-sulfate by both extracts.

The metabolism of dehydroepiandrosterone sulfate and dehydroepiandrosterone

Aging Male, 1998
Dehydroepiandrosterone sulfate (DHEAS), one of the major secretory products of the adrenal glands, is cleared very slowly from the circulation with a t1/2 of 13.7 h and a metabolic clearance rate of 15.5 1/day. This slow metabolism is due, largely, to its strong binding to serum albumin, and its renal tubular reabsorption.

Behavioral correlates of dehydroepiandrosterone and dehydroepiandrosterone sulfate

Aging Male, 1998
The actions of dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) on the central nervous system have been described as neurotropic, excitatory, and neuromodulator and may form the basis of various psychological effects in humans. Two research strategies help to define a possible role for DHEA and DHEAS in human behavior: first, to

Dissociation of Serum Dehydroepiandrosterone and Dehydroepiandrosterone Sulfate in Septic Shock [PDF]

The Journal of Clinical Endocrinology & Metabolism, 2006
Dehydroepiandrosterone (DHEA) replacement in sepsis has been advocated because of the sepsis-associated decrease in serum DHEA sulfate (DHEAS). However, experimental sepsis in rodents leads to down-regulation of DHEA sulfotransferase, which inactivates DHEA to DHEAS, theoretically resulting in higher DHEA levels.The objective of the study was to test ...

Serum Dehydroepiandrosterone, Dehydroepiandrosterone Sulfate, and Pregnenolone Sulfate Concentrations in Patients with Hyperthyroidism and Hypothyroidism [PDF]

Clinical Chemistry, 2000
AbstractBackground: Dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEA-S) have been suggested to have protective effects against cardiovascular disease, cancer, immune-modulated diseases, and aging. We examined serum concentrations of DHEA, DHEA-S, and pregnenolone sulfate (PREG-S) in patients with thyroid dysfunction.Methods ...

Dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) as neuroactive neurosteroids [PDF]

Proceedings of the National Academy of Sciences, 1998
The observation was made that dehydroepiandrosterone (DHEA), as the unconjugated steroid, and its sulfate ester (DHEAS) are present in the brain of adult male rats (1). This finding was unforeseen because the rodent steroidogenic glands, including the adrenals, do not secrete significant amounts of DHEA (2).

Quantification of steroid hormones in free‐ranging Apennine wolf Canis lupus italicus hair samples collected post‐mortem

Wildlife Biology, EarlyView.
After decades of dramatic reductions in their populations, Italian wolves have begun recolonizing parts of their historic range. This growth in populations can lead to potential conflicts with human activities, which remain the main cause of wolf mortality.

Fecal Glucocorticoid and Androgen Metabolites in Eastern Grey Kangaroos (Macropus giganteus) Following Environmental Relocation

Zoo Biology, EarlyView.
Fecal glucocorticoid (GCM) and androgen metabolite (AM) concentrations were monitored for 3 months following the relocation of three eastern gray kangaroos (Macropus giganteus) between zoological facilities. Both metabolites showed high concentrations during the early postrelocation period, followed by a rapid decline and stabilization, suggesting ...
