Steroids and Steroid-Sparing Agents in Asthma
New England Journal of Medicine, 1988Asthma is a disease characterized by an increase in airway reactivity together with a propensity for the airways to constrict in response to a variety of stimuli.1 The cumulative prevalence of this disorder in America is estimated to be between 5 and 7 percent.2 Prompt, regular, and aggressive therapy with inhaled beta-adrenergic agents, theophylline ...

Journal of Steroid Biochemistry, 1975
Abstract The unopposed continuous administration of biologically active estrogenic materials produces a wide variety of cancers in experimental animals. Most of these cancers occur in the target tissues for estrogenic activity and appear to be characteristic of the animal rather than the estrogens.

Hormone Research, 1986
Somatomedin levels measured by radioreceptor assay, competitive protein-binding assay or radioimmunoassay are normal in hypercortisolism; the decrease of somatomedin activity consistently found in this condition is due to an increase in circulating somatomedin inhibitors resulting in an inhibition of somatomedin action. Progestagens could possibly have

Steroid-Induced, Steroid-Producing, and Steroid-Responsive Tumors
1976As an introduction to the chapters to follow, this report will aim to present certain hopefully provocative observations on the nature of steroid-related tumors in man and animals.

Steroid derivatives as inhibitors of steroid sulfatase
The Journal of Steroid Biochemistry and Molecular Biology, 2013Sulfated steroids function as a storage reservoir of biologically active steroid hormones. The sulfated steroids themselves are biologically inactive and only become active in vivo when they are converted into their desulfated (unconjugated) form by the enzyme steroid sulfatase (STS).

Steroids, neuroactive steroids and neurosteroids in psychopathology
Progress in Neuro-Psychopharmacology and Biological Psychiatry, 2005The term "neurosteroid" (NS) was introduced by Baulieu in 1981 to name a steroid hormone, dehydroepiandrosterone sulfate (DHEAS), that was found at high levels in the brain long after gonadectomy and adrenalectomy, and shown later to be synthetized by the brain.

Non-Steroidal Steroid Receptor Modulators
Current Medicinal Chemistry, 2005The last ten years much attention has been focused on the finding of non-steroidal ligands for steroidal nuclear receptors for reasons such as diminishing cross-reactivity to eliminate side effect profiles, changing physicochemical properties which might cause different tissue distribution profiles and altering binding modes which influence the binding

Steroids, steroid precursors, and neuroactive steroids in critically ill equine neonates
The Veterinary Journal, 2017Hypothalamic-pituitary-adrenal axis (HPAA) dysfunction has been associated with sepsis and mortality in foals. Most studies have focused on cortisol, while other steroids have not been investigated. The objectives of this study were to characterise the adrenal steroid and steroid precursor response to disease and to determine their association with the

Profiling steroid hormones and urinary steroids
Journal of Chromatography B: Biomedical Sciences and Applications, 1986This paper reviews techniques utilized in the profiling of steroids in body fluids and tissues. Methods for profiling plasma unconjugated steroids and urinary steroid metabolites are focused on. Concentrations or levels of excretion of a variety of steroids have been documented and reviewed. The importance of profiling techniques in the study of normal
