This chapter discusses various substances and therapies for dermatological applications, including heliotherapy, UVB, khellin, and others, but reports no new research findings.

Acne is a common skin condition linked to diet, hormones, and genetics, and early treatment can prevent scarring.

This study investigated the Mandarin duck as a model for understanding lifelong developmental changes, finding that male sail feather morphogenesis involves a combination of local morphogenetic programs, epigenetic regulation, and hormonal cues, with increased female estrogen levels observed before the mating season.

This study reviews current treatments for alopecia areata, highlighting that despite various options like corticosteroids and immunosuppressives, their limited efficacy and potential side effects are challenges, while targeting specific cytokines has shown promise except with TNF inhibitors, which may worsen the condition.

This article reports no new data; it describes the role of sebum in influencing the skin microbiome and epithelial tissues and discusses its altered composition during transit through the sebaceous duct.

This abstract does not report specific research results but introduces a book focusing on the intersection of endocrinology and aesthetic medicine and its growing importance in contemporary clinical practice.

This study introduces stem cell activity as a key factor influencing the effects of IFN-γ and TGF-β1 on autoimmune disease dynamics, showing that varying cytokine levels can modulate stem cell activity and immune privilege, impacting tissue regeneration and disease flares.

This report details a six-month pharmacy internship in Portugal, where the author engaged in hospital and community pharmacy settings, and discusses scientific topics including obesity medication risks and alopecia treatment options. Results and conclusions are not explicitly reported.

This literature review reports that treatments for alopecia areata, including topical and intralesional corticosteroids, provide varied responses, and emphasizes the importance of supporting patients emotionally, given the limited and promising evidence of effectiveness for other treatments.

This review discusses the impact of chemotherapy-induced alopecia on cancer patients, the current use of scalp cooling for prevention, and potential future treatments, but presents no new clinical results.

This review outlines the proposed theories behind the development of alopecia areata, emphasizing the autoimmune process involving lost immune privilege in hair follicles, and stresses the need to pinpoint specific pathogenic mechanisms for potential treatments.

In this study, a clear pattern of selective sweep was observed for the SLC24A5 gene, with high linkage disequilibrium and low haplotype diversity, but no clear correlation with UV radiation intensity was found.

This study found that fetal canine hair follicle-derived stem cells exhibited pluripotency markers, suggesting potential for therapeutic applications in hair and skin repair.

Hyperpigmentation is common in pregnancy and may not fully fade after birth; melasma, also frequent, can persist but has limited treatment options during pregnancy.

This review summarizes the roles of bone morphogenetic proteins in the development and regulation of normal and diseased skin, but it does not provide new clinical results.

This review summarizes recent multidisciplinary advances in sebaceous gland research and highlights potential novel therapeutic strategies for skin diseases, but it reports no new clinical results.

This review examines the neuroendocrine mechanisms underlying seasonal changes in mammals and highlights areas needing further research, reporting no new experimental results.

This review explores animal models of alopecia areata, particularly focusing on the insights they've provided into the disease's immune mechanisms and potential treatment approaches, without reporting new experimental data.

This review discusses the roles of interferon-γ and PPAR-γ-mediated signalling in scarring alopecia, suggesting these pathways as potential therapeutic targets, but it reports no new empirical results.

This study suggests that CD8+ cytotoxic T lymphocytes play a crucial role in the development of alopecia areata, based on observations in rodent models that mimic human autoimmune disease.

This review discusses prolactin production and regulation in human skin and hair follicles, highlighting its potential broader implications but reports no new empirical results.

This essay reviews the role of human scalp hair follicles in the "brain-skin connection," highlighting their dual function as targets and sources of neurohormones, without reporting new experimental results.

In this study, inactivating the TAF4 subunit of transcription factor TFIID in mouse epidermis disrupted gene expression linked to skin and hair function, and increased tumor risk.

The researchers reported that they successfully developed and validated RP-HPLC and TLC methods for accurately measuring tamsulosin hydrochloride and finasteride in combination forms.

This study describes a new colorimetric method for accurately and precisely measuring finasteride in tablets, with results comparable to the standard HPLC method.

New, cheaper method measures finasteride in tablets accurately and quickly.

This study found that the solubilities of flutamide, dutasteride, and finasteride in supercritical carbon dioxide were effectively modeled using semiempirical equations by Chrastil and Bartle, with varying levels of accuracy.

This review discusses the multifaceted roles of hair follicles in skin health, including potential contributions to skin neoplasias, and reports no new results.

Method accurately measures finasteride in tablets using finasteride-BSA interaction.

This study developed and validated a reliable method to measure finasteride levels in human plasma, which was successfully used to assess its pharmacokinetics after a 5 mg dose in healthy volunteers.
