Recently, measurements of steroids like testosterone, androstenedione, cortisol and cortisone in saliva are more and more applied in diagnostics and scientific studies. This is mainly due to the simple and non-invasive collection of saliva. We aimed to evaluate the optimal way to collect saliva for steroid hormone measurement.

The retrospective analysis of endogenous steroid hormones in nails can be used to elucidate endocrine diseases and thus help with their diagnosis and treatment. A liquid chromatography-tandem mass spe...
This study examines steroid production in fathers watching their children compete, extending previous research of vicarious success or failure on men's hormone levels. Salivary testosterone and cortis...
Adrenal venous sampling (AVS) is the reference standard for primary aldosteronism (PA) subtyping. Cortisol is widely used to assess the success of selective AVS, but it is not always reliable. The aim...
Experimental evidence to-date largely supports an association between the stress hormone cortisol and cognitive performance. Older adults, in particular, may be vulnerable to the neurotoxic effects of...
A large body of research links testosterone and cortisol to male-male competition. Yet, little work has explored acute steroid hormone responses to coalitional, physical competition during middle chil...
The purpose of this study is to determine whether hair levels of cortisol and testosterone are elevated in patients with acute MI compared to controls.
Many type 2 diabetic men have low serum testosterone levels. Our aim in this trial is to check if there is a correlation between serum or hair testosteron levels and serum or hair cortiso...
Aldosterone, the major mineralocorticoid hormone and cortisol, the major glucocorticoid hormone are produced in the adrenal gland. Aldosterone binds intracellular mineralocorticoid recepto...
Rheumatoid arthritis is the paradigmatic immune-mediated inflammatory arthropathy. With respect to rheumatoid arthritis (RA), patients have been described as having inappropriately low sp...
The investigators studied whether scalp hair cortisol and testosterone levels differed between sarcoidosis patients both with and without fatigue and healthy controls.
A hereditary disease characterized by childhood onset HYPERTENSION, hypokalemic alkalosis, and low RENIN and ALDOSTERONE secretion. It results from a defect in the activity of the 11-BETA-HYDROXYSTEROID DEHYDROGENASE TYPE 2 enzyme which results in inadequate conversion of CORTISOL to CORTISONE. The build up of unprocessed cortisol to levels that stimulate MINERALOCORTICOID RECEPTORS creates the appearance of having excessive MINERALOCORTICOIDS.
A delta-4 C19 steroid that is produced not only in the TESTIS, but also in the OVARY and the ADRENAL CORTEX. Depending on the tissue type, androstenedione can serve as a precursor to TESTOSTERONE as well as ESTRONE and ESTRADIOL.
A potent androgenic steroid and major product secreted by the LEYDIG CELLS of the TESTIS. Its production is stimulated by LUTEINIZING HORMONE from the PITUITARY GLAND. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to DIHYDROTESTOSTERONE or ESTRADIOL.
Hydroxysteroid dehydrogenases that catalyzes the reversible conversion of CORTISOL to the inactive metabolite CORTISONE. Enzymes in this class can utilize either NAD or NADP as cofactors.
An enzyme that catalyzes the interconversion of a ketone and hydroxy group at C-20 of cortisone and other 17,20,21-trihydroxy steroids. EC 126.96.36.199.

Endocrine disorders are grouped into two categories: hormone imbalance - when a gland produces too much or too little of an endocrine hormone development of lesions (such as nodules or tumors) in the endocrine system, which may or may not affect...
