This review discusses the influence of androgens on opioid-mediated effects and calls for further research into their role in sex differences and potential therapeutic options for chronic pain and substance use disorders.

This article discusses the paradoxical effects of valproic acid on hair, reporting both drug-induced hair loss and the potential for hair growth when used topically, but presents no original research findings.

This review summarizes recent findings on how Wnt signaling proteins play crucial roles in the cutaneous wound healing process but reports no new clinical results.

This study found associations between genetic predictors of increased testosterone and cardiovascular risk factors, but the implications for testosterone supplementation are unclear due to uncertainties in genetic variant functions.

This case report describes a Russian wolfhound's aggression being linked to hypothyroidism, which was successfully managed with levothyroxine therapy.

This study found that melatonin upregulates LncRNA16913.1, which sequesters chi-miR-195-5p to release FZD6 and enhance fibroblast proliferation in cashmere goat skin, suggesting a regulatory mechanism within the lncRNA-miRNA-mRNA cascade in vitro.

This study concluded that anabolic-androgenic steroids negatively impact male reproductive health, including reduced testosterone production, impaired sperm production, and increased risk of sexual dysfunction and metabolic issues.

This study developed a new analytical method to identify a wide range of endocrine disrupting compounds in full-term amniotic fluid, revealing diverse substances with potential endocrine activity.

This case report highlights that a postmenopausal woman experienced virilization due to unintentional transdermal absorption of testosterone from her spouse's topical androgen via shared washcloths, underscoring the importance of considering exogenous androgen exposure in similar diagnoses.

This review discusses the relationship between gut microbiota and polycystic ovarian syndrome (PCOS), including its potential mechanisms and the role of alterations in microbiome composition on PCOS pathophysiology.

This review discusses the complex relationship between melasma and factors like female sex hormones, genetics, and ultraviolet light exposure, but reports no new clinical findings.

This study found that injecting melatonin in female goats did not significantly affect follicle characteristics but did improve cashmere yield, potentially by enhancing secondary follicle growth and extending the cashmere growth period.

This study concluded that there was no consistent association between endogenous sex hormone levels and atopic dermatitis in the populations studied.

This study found that lncRNA H19 may regulate CTGF expression in KGN cells by acting as a "sponge" for miR-19b, potentially influencing polycystic ovary syndrome development.

This review discusses the role of jasmonic acid and its conjugates in enhancing plant stress tolerance and balancing growth and defense mechanisms but provides no new experimental data.

This study identified and analyzed numerous lncRNAs, miRNAs, and mRNAs involved in hair follicle development in cashmere goats, highlighting key regulatory pathways and suggesting roles for specific RNAs in enhancing hair follicle cell proliferation.

This study identified that in pig embryos, the miR-29a-5p/EDAR/lncRNA627.1 ceRNA complex plays a critical role in inhibiting hair placode precursor cells proliferation and regulating hair placode formation through the suppression of EDAR expression, which may provide insights into similar mechanisms affecting human hair conditions.

This study reports a successful combination treatment for phospho-organic compound poisoning, using standard therapy with atropine and toxogonin along with exogenous cholinesterases via blood transfusion, showing positive outcomes in patients whose endogenous cholinesterase levels dropped to 20%.

This study explored the use of multiphoton microscopy to monitor changes in tumors and surrounding tissues in breast cancer patients undergoing neoadjuvant chemotherapy, finding it may effectively detect treatment response at cellular levels without using exogenous contrast agents.

This study found that higher levels of DHA from omega-3 fatty acids delayed inflammation resolution and impaired wound healing quality in both transgenic mice and wild-type mice supplemented with DHA.

Hair chromium levels reflect nutritional status after standard washing.

This study found that exogenous EGF inhibited hair follicle development and decreased follicle density in both Tabby and normal mice, suggesting interactions between EGF and the Ta peptide influence normal skin phenotype.

This study found that exogenous melatonin improved cashmere fiber quality and yield in goats by enhancing antioxidant capacity and reducing pro-aging cytokine expression in secondary hair follicles.

This study found that reducing testosterone levels in male mice accelerates wound healing and decreases inflammation, suggesting a potential therapeutic target for improving wound repair in elderly males.

This study found that 3-indolebutyric acid (IBA) increased root-hair growth in trifoliate orange by elevating auxin levels, while 2-naphthoxyacetic acid (2-NOA) had the opposite effect, inhibiting root-hair growth.

This study found a negative correlation between dietary monoene levels, particularly oleic acid, and the capacity for PGE₂ synthesis in rat skin, with the most severe skin issues noted in those fed Zephyr rapeseed oil.

This study concluded that an endogenous circannual rhythm of prolactin secretion in mouflon influences their seasonal hair growth and moulting cycle, which varies under different photoperiodic and melatonin treatments.

This study found that leukocytes and beard hair follicle cells have an endogenous circadian clock, with PER1 and PER3 expression possibly serving as biomarkers for assessing individual biological clock traits.

This study suggests that epidermal turnover could be a regulated mechanism of iron excretion, with systemic iron levels influencing keratinocyte behavior and differentiation markers in the skin.

This study found that formalin-induced pain in rats nearly eliminates testosterone in the brain and spinal cord by likely increasing 5α-reductase activity, but normalizes serum levels after 24 hours.
