This article discusses perioral dermatitis and reports no new results; the authors present two cases implicating fluoride toothpaste as a potential cause.

This study observed that human hair follicles with a completely destroyed bulb can regenerate after being grafted onto immunodeficient mice, entering a shortened dystrophic telogen followed by anagen phase.

This review discusses the potential link between long-term transdermal exposure to sex hormones from antiperspirants and increased breast and prostate cancer rates, calling for further research to confirm this theory.

This study cataloged several long non-coding RNAs and microRNAs in cashmere goat dermal papilla cells, suggesting these non-coding RNAs may play a role in hair follicle stem cell activation and hair growth.

This review discusses the dual role of the TMPRSS2 gene in coronaviral lung infection and prostate cancer, cautioning against TMPRSS2 inhibitors for early prostate cancer due to potential pro-inflammatory effects.

This review discusses the varied roles of Wnt7a in development, tissue homeostasis, and cancer, reporting no clinical results; the authors emphasize the need for further investigation on its roles in inflammation and fibrosis.

ACTH promotes hair growth in mink, but α-MSH does not.

This review examines recent research on melatonin's biochemical activities, particularly in skin health, but reports no new clinical results and emphasizes its potential for future medical applications.

This study found that co-applying Curcuma aeruginosa extract or essential oil with minoxidil significantly increased minoxidil's skin penetration in an ex vivo setting, suggesting an improved topical treatment strategy for androgenic alopecia with greater efficacy and the potential for lower minoxidil doses.

This study describes the presence of holes in hair fibers, absent in hair follicles, likely forming from daily care actions and removal of extractable substances.

This study found diverse responses to the androgen dihydrotestosterone in rodent tissues, with most androgen-regulated processes being specific to particular tissues.

This study found that the cytokine-mediated signaling pathway is the primary pathway disrupted in skin after CO2 laser surgery.

This review discusses the diverse roles of PPARβ/δ in skin health and disease, including its involvement in skin wound healing and inflammatory skin conditions, without presenting new experimental results.

This report presents a case of a superficial angiomyxoma with a trichofolliculoma in a 51-year-old man, characterized by myxomatous nodules and specific immunohistological markers.

This study demonstrated that human dermal mesenchymal stem cells can be differentiated into cardiomyocytes using 5-azacytidine, suggesting potential future applications for treating myocardial infarction.

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 found that after topical application in rats, 1,24-dihydroxyvitamin D3 absorbed through both the stratum corneum and hair follicles, with about 30% excreted via the faeces.

This article discusses the mechanisms of hirsutism and acne in women, highlighting cyproterone acetate with ethinyloestradiol as an effective anti-androgen therapy in the UK, but it reports no new clinical findings.

This study found that deficiency in TLR3/TRIF signaling reduced inflammation and protected mice against postoperative ileus, suggesting potential for TLR3 antagonism as a preventive approach in humans.

In this study, despite morphological differences in the hair growth cycle stages, the lipid composition of the epidermis and dermis showed no significant variation, though water content and cholesterol levels differed between these skin layers.

This study used a probabilistic Boolean network model to explore hair follicle cell fate regulation and predicted that varying TGF-β levels, in coordination with BMP and TNF, can influence either apoptosis or cell proliferation during different follicle growth stages.

This paper reviews the role of androgens in SARS-CoV-2 infection and their potential impact on disease severity, suggesting androgen-targeting strategies might influence outcomes, but reports no new clinical results.

This review found that platelet-rich plasma shows potential in improving melasma, though its overall benefit varies across different treatment methods and may not enhance results when combined with certain other treatments.

This review discusses the protective and reparative properties of chitin nanofibrils on hair structure and reports no clinical results; the authors suggest chitin-based products may aid in hair regrowth.

This article introduces a hypothesis that the enzyme catalase in processed meats may be a probable cause of higher cancer incidence due to its emission of electromagnetic fields, but no new clinical results are provided.

This review discusses the roles of glucocorticoid and sex hormone receptors in the skin and their clinical importance, but reports no new research findings.

This study observed that extracellular ATP (eATP) levels outside Arabidopsis root cells vary inversely with the expression of AtAPY1 and AtAPY2 apyrases, suggesting these enzymes regulate eATP concentrations crucial for root growth.

In this study, dimeric peptide derivatives were shown to enhance the proliferation of human follicle dermal papilla cells in vitro, particularly promoting the ERK1/2 pathway, suggesting potential for developing peptide-based treatments for hair regeneration.

This case series reports promising initial data on using microneedling with a dermaroller in trichotillomania patients, indicating potential efficacy in reducing compulsive hair-pulling behaviors and promoting hair regrowth.

This study found that fibronectin is crucial for hair follicle stem cell function and regeneration, with its deletion impairing regeneration but restoration by dermal injection of exogenous fibronectin.
