Previous reports on patients with endogenous Cushing's syndrome describe low concentrations of the adrenal androgen dehydroepiandrosterone sulfate (DHEA-S) in adrenal adenoma and in a case of feminizing macronodular hyperplasia. Here we present hormonal data from two adult sisters with Cushing's syndrome as a result of pigmented nodular adrenal dysplasia. Corticotropin concentrations were in th...

Accumulating data indicates that neurosteroids can modulate aggressive behavior. The aim of the present study was to examine neurosteroid blood levels in delinquent adolescent boys as compared to normal healthy controls. Dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEA-S) and cortisol blood levels were measured in 16 delinquent adolescent (age 15.72+/-0.95 years) with conduct...

Ovarian and adrenal function were studied in premenopausal breast cancer patients before and at intervals during adjuvant therapy with cyclophosphamide, methotrexate, and 5-fluorouracil (CMF), CMF plus prednisone (CMFP), or CMFP plus tamoxifen (CMFPT). Amenorrhea developed within 10 months of starting therapy in 13 of 15 patients given CMF, 8 of 10 receiving CMFP, and all of 13 CMFPT-treated pa...

Normal aging in humans has been recently shown to be accompanied by reduced control over production of the multifunctional cytokine IL-6. This cytokine was reported to be quantitatively elevated in most serum samples obtained from "normal" elderly humans. In the present investigation, we report that IL-6 levels are elevated in serum samples obtained from aged mice, and its spontaneous productio...

We tested the hypothesis that older men (n = 9, 69 +/- 2 years) would experience greater resistance-training-induced myofiber hypertrophy than older women (n = 5, 66 +/- 1 years) following knee extensor training 3 days per week at 65-80% of one-repetition maximum for 26 weeks. Vastus lateralis biopsies were analyzed for myofiber areas, myosin heavy chain isoform distribution, and levels of mRNA...

Neuroactive steroids refer to steroids that are capable of regulating neuronal activities. Neuroactive steroids, synthesized either de novo in the nervous tissue or in the peripheral endocrine glands or as synthetic steroids, have exhibited numerous important modulatory effects on brain functions and brain diseases. At the cellular level, in addition to the effect on postsynaptic receptors, mos...
