This study describes the expression patterns of type I inner root sheath keratin proteins K25–K28 in human hair follicles, highlighting their distinct distribution within different layers.

This study found that while male COVID-19 patients in Brazil exhibited more severe symptoms and required more intensive care than females, the difference in risk of death was relatively small.

This study found that dexpanthenol treatment reduced inflammation, oxidative stress, and apoptosis in rats, providing a protective effect against lipopolysaccharide-induced cardiac and endothelial damage.

This review reports that sex-related differences in pharmacological response have been observed in SARS-CoV-2 infection, dyslipidemia, and diabetes mellitus, with implications for treatment strategies; for example, men may respond better to genomic vaccines for SARS-CoV-2, while women may benefit more from certain antiviral medications.

In this study, ALR was found to enhance both the proliferation and osteogenic differentiation of mouse bone marrow mesenchymal stem cells, potentially through specific signaling pathways.

This review discusses the characteristics, complications, and treatment options for hidradenitis suppurativa, a chronic skin disorder with systemic effects, without presenting new clinical findings.

This paper outlines the chronic inflammatory skin disorder hidradenitis suppurativa, emphasizing its symptomatology, associated systemic diseases, known risk factors, and treatment strategies, including medical and surgical interventions depending on disease severity, while highlighting its significant impact on patients' quality of life.

Baricitinib reduces inflammation and mitochondrial damage in skin cells.

This study found that udenafil-treated adipose-derived stem cells accelerated hair growth in mice by enhancing stem cell activity and growth factor secretion through the ERK and NFκB pathways.

This study found that the detection rate of clinically insignificant prostate cancer increases with the number of repeat prostate biopsies in patients with persistently suspicious prostate cancer.

This study found that using an LED array with an 863 nm wavelength delayed tumor development and reduced systemic inflammatory cytokines in DMBA/TPA-induced mouse skin tumors, suggesting potential but limited benefits of light therapy.

This case study reports on a 13-year-old male with alopecia totalis who experienced successful hair regrowth after being treated with dupilumab, an interleukin-4 and IL-13 antagonist, suggesting its potential utility in managing alopecia areata in pediatric patients with comorbid atopic dermatitis.

The researchers reported that dPGS-PCL as a carrier improved the penetration of tofacitinib in an ex-vivo human skin model compared to free tofacitinib, but did not show significant differences in inhibiting IL-6 and IL-8 during short incubation.

This study found that glycyrrhetinic acid, derived from licorice, may help alleviate acne symptoms by regulating lipid synthesis and inflammatory responses through multiple pathways, as observed in both in vitro and in vivo settings.

In a study using a mouse model of diabetes, chitosan-based hydrogels increased healing markers and improved wound closure and tissue repair compared to untreated wounds, but human efficacy needs further validation.

This study found that applying AGN root extract containing decursin to mouse skin accelerated hair growth and altered inflammatory cytokine levels compared to a control.

This study found that adipose-derived stem cell-conditioned media improved skin flap survival following ischemia/reperfusion injury in mice by increasing cell proliferation and the number of hair follicles, mediated by IL-6.

This narrative review discusses the challenges and special care needs of laryngectomy patients with tracheoesophageal bypass during the COVID-19 pandemic and reports no new clinical results.

In this prospective study, 15 patients with patchy alopecia areata treated with intralesional methotrexate every two weeks showed a significant improvement in hair regrowth and reduction in lesion severity, with changes linked to decreased tissue levels of TNF-α.

In this study, women with PCOS who took 12 mg of Astaxanthin daily for 8 weeks showed a reduction in certain inflammatory markers and apoptosis-related genes, suggesting potential benefits for managing PCOS, though effects on symptoms like BMI and hirsutism were not significant.

In this study, ginger peel polysaccharides modified with zinc reduced inflammation in zebrafish by altering cytokine expression, suggesting potential for treating chronic inflammation-related diseases.

This study observed that Epigallocatechin-3-gallate (EGCG) can inhibit phosphorylation of STAT1 and reduce a specific subset of immune cells in vitro and ex vivo, suggesting a potential role in maintaining immune privilege in alopecia areata.

This study found that Callicarpa nudiflora water extract significantly accelerated wound healing and improved skin repair in deep second-degree scalds in rats, supporting its traditional medicinal use.

This study found that administering dupilumab to patients with moderate-to-severe atopic dermatitis over 12 weeks altered both fungal and bacterial skin microbiomes, increasing microbial diversity and decreasing colonization by Malassezia and Staphylococcus aureus at lesion sites.

This study found that sex hormones, specifically non-aromatizable androgens like DHT and A/T, significantly increase inflammatory cytokine expression in human adipocytes when stimulated by LPS.

This study explored the effects of DPP, a 15-PGDH inhibitor, on human follicle dermal papilla cells damaged by dihydrotestosterone and observed that DPP enhanced wound healing, reduced reactive oxygen species, and increased hair growth in ex vivo human hair follicle cultures.

In this study, NMN was found to reverse hair follicle atrophy, thinning, and sparsity in mice induced by DHT, and significantly decreased DHT-induced inflammation and oxidative stress in cultured human dermal papilla cells, enhancing hair growth-related markers.

This study explored the mechanism of Shaoyao Gancao decoction in treating alopecia areata and found that it may be closely related to the PI3K/AKT signaling pathway.

This study found that platelet-rich growth factor significantly reduced the release of proinflammatory cytokines in an in vitro rheumatoid arthritis model.

This review discusses oxidative stress in alopecia areata pathogenesis and potential treatment strategies, reporting no new clinical results but suggesting biomarkers for oxidative stress and discussing JAK inhibitors as promising options.
