Stress can cause hair to turn gray by depleting stem cells.

This case study reports a patient with ACTH-driven cortisol secretion 14 years after adrenalectomy, suggesting possible residual adrenal tissue or extra-adrenal steroid synthesis, challenging the need for lifelong steroid replacement.

This case study illustrated that a patient's severe autonomic neuropathy due to amyloidosis prevented the expected development of heart failure symptoms despite significant cardiac abnormalities.

In this case study, a 44-year-old woman with an adrenal adenoma secreting both cortisol and androgens developed Cushing syndrome and significant virilization, but experienced major symptom improvement following surgical removal of the benign tumor.

This review discusses the potential antidepressant effects of phenylalanine, highlighting its significant activity in laboratory studies, but reports no new clinical findings.

This report details a case study where a 40-year-old woman experienced allergic contact dermatitis and angioedema-like symptoms after using PPD-containing hair dye. Patch testing confirmed a positive reaction to PPD, highlighting the substance's potential to cause both T-cell and IgE-mediated hypersensitivity reactions.

This study describes a method to estimate endogenous hormone production by neutralizing an endogenous hormone with an oppositely acting hormone.

This review discusses how dehydroepiandrosterone (DHEA) may exert its biological effects through multiple receptors and reports no new clinical results.

Blocking CYP17A1 enzyme may help improve certain brain function issues related to dopamine.

This study found that the pH dependency of rat steroid 5α-reductase type II isozyme significantly affects its kinetic properties, including Vmax and Km, suggesting past discrepancies in literature may arise from these pH variances during assays.

This study found that systemic administration of NDP-MSH, a melanocortin receptor agonist, provided neuroprotective effects on dopaminergic nigrostriatal neurons in a mouse model of Parkinson's disease, reducing neuroinflammation and suggesting a role for regulatory T cells in these neuroprotective effects.

This case study reported a unique instance of a benign adrenal adenoma co-secreting cortisol and DHEA-S, which initially mimicked PCOS symptoms. Surgical removal resulted in significant clinical improvement, confirming the diagnosis of cyclic adrenal Cushing's syndrome.

In this study, anabolic and catatoxic steroids were reported to prevent weight loss, tissue calcification, and cardiac necrosis in a rat model of disturbed calcium metabolism and progeria-like syndrome.

This study found that 1,25 dihydroxyvitamin D3 significantly increased the expression and activity of vasculoprotective natriuretic peptide receptor-A in cultured inner medullary collecting duct cells, suggesting a potential mechanistic role in cardiovascular and renal benefits.

This study found that a new deoxycholic acid derivative may offer a similar prostatoprotective effect to finasteride with lower toxicity in rat models.

This study found that rat male costochondral chondrocytes, unlike female chondrocytes, respond to testosterone through metabolism to dihydrotestosterone, which shows a maturation-state dependent effect in male growth plate cells.

Minoxidil reacts to nitrosation 7 times more than phenol, mainly due to its -NH₂ groups, leading to the creation of N-nitrosominoxidil.

This study describes a case of a 35-year-old woman who developed symptoms of hyperandrogenism and disrupted steroidogenesis due to chronic use of electronic cigarettes containing compounds similar to etomidate, despite no genetic mutation indicating 11β-hydroxylase deficiency.

This review summarizes the use of chlormadinone acetate for hormone replacement therapy and contraception, highlighting its anti-androgenic effects, contraceptive efficacy, and clinical tolerability, without offering new clinical results.

This study suggests that epitestosterone may play a role in regulating androgen-dependent processes like prostate growth and body hair distribution by counteracting testosterone's actions.

In this study, 17β-estradiol increased VEGF production in differentiated THP-1 cells, while dihydrotestosterone counteracted this effect by modulating adenylate cyclase activity.

In this study, adrenalectomy in black rats on a vitamin B-deficient diet restored hair growth and melanin deposition, effects reversed using adrenal cortical hormones.

This study examined the vasorelaxant effects of two similar alkaloids, chloroquine and cinchonine, in a model of smooth muscle contractions induced by phenylephrine. Results are not reported in the abstract.

In this study, adolescents with depressive symptoms were found to have higher urinary excretion rates of certain steroid metabolites, including corticosterone and adrenal hormones, and a specific metabolite ratio was identified as a potential biomarker for distinguishing these patients from healthy controls.

This study developed the CATNIP computational model, which uses biological and chemical information to successfully identify drug repurposing opportunities for various conditions, including Parkinson’s disease and Type 2 Diabetes.

This study found that androgens, specifically DHT, induced neurite outgrowth in motor neurons by up-regulating the neuritin protein, with testosterone being less effective.

This study identified that the MC-5-HT-HTR2A axis plays a role in chronic pruritus in a mouse model of SADBE-induced allergic contact dermatitis, suggesting potential for therapeutic targeting.

In this study, HDAC inhibitors promoted the differentiation of rat C6 glioma cells through the production of 5α‐reduced neurosteroids, enhancing serotonin-stimulated BDNF gene expression.

This study found that dexamethasone may induce diabetes in albino rats and Annona muricata methanolic bark extract resulted in significantly reduced blood sugar levels in dexamethasone-induced diabetic rats.

This review discusses the historical development, mechanisms of action, and potential new clinical applications of the drug cepharanthine, highlighting its multi-faceted pharmacological properties; it reports no new clinical results.
