This study found that keratin-75, discovered in enamel tissue, is secreted by ameloblasts using an unconventional pathway involving the ER-Golgi-Intermediate-Compartment and Golgi, differing from typical cytokeratin localization.

This study found that proretinal nanoparticles, applied topically, are safe and effective for penetration into hair follicles, enhancing retinoid biological activity in the skin while reducing irritation compared to conventional retinal formulations.

This study found that neonatal administration of finasteride reduced sensitivity to alcohol's motor-stimulating effects and increased preference for novelty and initial alcohol consumption in rats, suggesting a role in alcohol vulnerability.

Activating the Eda/Edar pathway improves wound healing by enhancing hair follicle growth.

In this study, researchers found that alopecia areata is linked to immune cell activation against hair follicle autoantigens and is associated with heart changes and cardiac marker alterations in humans and mice.

This study observed that stem cells from the hair follicle dermis share similarities with bone marrow-derived mesenchymal stem cells and have potential to form neural-like cells under specific conditions.

This article reviews the discovery and various physiological effects of cyproterone acetate, reporting its established indications for several androgen-driven conditions but providing no new clinical data.

This review discusses advances in 5α-reductase inhibitors for treating male androgenetic alopecia and reports no new clinical results.

This study observed that a significant majority of participants who used the dietary supplement Nutrifii™ Renew reported improvements in various health outcomes, including sleep and energy, compared to a multivitamin/mineral group.

This article reviews the role of IGF-1 in acne pathogenesis and discusses how diet and smoking may influence insulin/IGF-1 signaling, but reports no new clinical results.

In vitro, this study suggests that CRH may act as an autocrine hormone in human sebocytes, influencing lipid synthesis and potentially impacting skin disorders related to alterations in sebaceous lipid formation.

This study found that women with PCOS have higher ghrelin levels compared to controls, with ghrelin negatively correlating with BMI and insulin levels, suggesting its potential role in PCOS etiology.

This study found that monocytes/macrophages with a pro-inflammatory M1-like phenotype may play a crucial role in the pathogenesis of hidradenitis suppurativa, suggesting potential therapeutic targets.

This review outlines the adverse effects of glucocorticoid excess on bones, adipose tissue, brain, and skin, with a focus on the Wnt/β-catenin pathway, and reports no new research findings.

This review discusses androgen therapy in adolescents, detailing current practices and noting the limited use of commercially available testosterone or dihydrotestosterone formulations; no new results are reported.

This article discusses the various administration methods and considerations for testosterone replacement therapy, highlighting the importance of individualized therapeutic monitoring and potential adverse effects, but reports no new clinical results.

This study found that Neuregulin3 can influence the development and differentiation of mammary glands and epidermal features in mice, potentially by inducing c-Myc and altering cell proliferation and adhesion.

Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

In this study, sandalore was found to activate OR2AT4, which inhibits senescent cell traits and restores proliferation in human keratinocytes, suggesting potential anti-aging applications.

This review highlights the potential of nanotechnology-based formulations in hair care and treatment, emphasizing how these innovative materials can enhance the stability, efficacy, and safety of active compounds while addressing the limitations of conventional formulations.

This review discusses various types of stem cells used in regenerative medicine, including adult stem cells and induced pluripotent stem cells (iPSCs), and evaluates them based on their embryonic tissue origins to explore new therapeutic approaches.

This review concludes that anabolic–androgenic steroid abuse may lead to significant neurotoxicity, affecting brain structure, neurotransmitter systems, and increasing the risk of mood disorders and cognitive deficits.

This study suggests that targeting adenosine receptors could be an effective strategy for reducing inflammation in inflammatory skin disorders, with promising results observed in animal models.

This research observed that diabetes impairs wound healing in mice by disrupting key mechanotransduction pathways in fibroblasts, which are crucial for the healing process. The study also suggests transcriptomic changes could inform future diabetic wound repair therapies.

This study found that integrating machine learning enhances the predictive accuracy of forensic DNA phenotyping from low template DNA, achieving high accuracy for traits like eye color, although challenges remain for admixed populations and complex traits.

In this study, researchers found that isoproterenol, an adrenergic β2 receptor agonist, promoted hair growth and hair follicle stem cell proliferation in models of androgenetic alopecia by modulating the PI3K/AKT/β-Catenin pathway, suggesting a potential new therapeutic strategy for hair loss.

This study suggests that persistent symptoms in patients with controlled functioning adenomas may indicate a coexisting PCOS diagnosis, highlighting the need for precise differentiation and timely management of these conditions.
