In this study, researchers found that in late pregnancy, the neuroactive progesterone metabolite allopregnanolone inhibits HPA axis responses to immune challenges via an opioid-mediated mechanism.

This article discusses the role of human hair follicles in neuroendocrinology and suggests potential new therapeutic targets by examining how neuromediators influence hair growth, pigmentation, and stem cell biology in organ cultures.

Higher 3α,5α-THP levels in the brain may reduce depression in pregnant rats.

This study found that cortisone reductase deficiency is caused by inactivating mutations in the H6PD gene, affecting cortisol metabolism by preventing 11β-HSD1 enzyme function.

This study found that gonadal dysfunction is very common in premenopausal women with acromegaly and may be caused by hyperprolactinemia, GH/IGF-I excess, or tumor effects.

This research highlights that psychological stress can adversely affect hair growth in mice, implicating potential pathways that may be relevant in understanding stress-induced hair growth inhibition in humans.

Acne is caused by genetics, diet, hormones, and bacteria, with treatments not yet curative.

This review discusses the complex relationship between stress and various skin conditions, highlighting the role of the skin in the stress response and the brain-skin communication pathways, but reports no new research findings.

The researchers reported that during early embryogenesis and larval development in Silurana tropicalis, inhibiting steroidogenic enzymes cyp19 and srd5beta affects genes related to thyroid and reproductive systems.

This review found that patients with depression generally have higher hair cortisol concentrations compared to healthy controls, while those with PTSD tend to have lower concentrations.

In this study, researchers found that tritiated cortisol was incorporated into the hair of rhesus monkeys primarily as cortisol and cortisone, as well as other metabolites, after systemic administration.

This review explores the complex relationship between thyroid hormones and skin, discussing potential mechanisms and known interactions but reports no new clinical results, emphasizing the need for further research.

In this study, socially defeated mice showed increased alcohol consumption, and CRF-R1 antagonism selectively reduced drinking in these mice, suggesting a potential treatment target for stress-related alcohol use disorders.

This review discusses the pharmacological properties and physiological regulation of neuroactive steroids, focusing on their varied responses to stress and ethanol in rats, mice, and humans, but it reports no new findings.

In this study, hair from forearms showed higher cortisol levels than hair from lower legs, suggesting a localized cortisol response in hair.

This presentation reviews recent discoveries about signaling mechanisms in hair follicles and their potential influence on hair cycle control and melanogenesis, without presenting new experimental results.

This study suggests that IGFBP-2 may play a role in basal cell carcinoma development by mediating epidermal progenitor cell expansion in hair follicles with activated Shh signaling.

This study found that finasteride impaired stress reactivity and reduced exploratory and impulsive behaviors in rats, potentially by altering the hypothalamus-pituitary-adrenal axis function.

This review examines the negative effects of anabolic-androgenic steroid use on the male reproductive system, including impaired testosterone production, sperm production issues, and adverse metabolic consequences without reporting new clinical results.

This review discusses the pathophysiology, diagnosis, and management of functional hypothalamic amenorrhea in adolescent girls and reports no new clinical results.

This study observed that Parkinson’s disease patients had higher hair cortisone, but not cortisol, levels compared to controls, and cortisone was significantly associated with mood-related non-motor symptoms.

This report describes a three-generation family with Cantú syndrome linked to a novel ABCC9 gene variant, featuring acromegaloid appearance and hypertrichosis without growth hormone abnormalities, and suggests a potential association with pituitary adenomas.

This review discusses potential treatments for androgen excess in polycystic ovary syndrome and reports no new findings, emphasizing the importance of individualized antiandrogenic management to minimize side effects.

This review highlights the critical role of neuroregulation in skin wound healing, emphasizing how neurotransmitters and neuropeptides regulate inflammation, angiogenesis, and cell proliferation, and discusses potential therapeutic strategies, such as neuromodulation, to enhance these processes.

This review discusses the interplay between dermatology and psychology in psychodermatology, highlighting the impact of neuroendocrine stress pathways on skin diseases and the importance of considering skin of color.

This study found that age-related fluctuations in hormones and endocannabinoids in male C57BL/6 mice showed specific patterns, with peak values observed around 2.7 to 3.4 months, with these patterns seen in both plasma and hair but with different magnitudes.

This review highlights the potential therapeutic applications of nandrolone, an anabolic steroid, for male health, but notes that more human studies are needed due to limited existing literature.

This study found that melatonin-loaded nanoparticles improved antidepressant effects and HPA axis regulation in pinealectomized rats, compared to free melatonin, through controlled-release properties.

This review discusses how COVID-19 may affect gonadal function and potential gender differences, but reports no clinical results; it highlights possible mechanisms and new treatment approaches from recent literature.

This study reports a good correlation between the curvature of human eyelashes and the displacement of the neutral axis, influenced by the non-uniform thickness of the outer cuticle layer.
