This review describes recent advances in using nanoparticles for drug delivery to hair follicles, with potential applications in treating skin diseases such as alopecia and acne, but reports no new findings.

This article proposes an updated naming system for keratin-associated proteins and genes, aiming to improve data storage and retrieval by including species information and genetic variation.

This study found that women with polycystic ovary syndrome have higher global adiposity and increased visceral fat, particularly in the ip and mesenteric depots, compared to women without androgen excess.

This review discusses the genetic factors involved in hair follicle morphogenesis and cycling and reports no new clinical results; it emphasizes the role of genes in hereditary hair diseases.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

This review discusses recent insights into the molecular mechanisms of hypohidrotic ectodermal dysplasia linked to TNFα-related signaling pathway mutations but reports no new experimental results.

This review examines cell senescence pathways in melanocytes, highlighting the involvement of telomere attrition, the p16/RB pathway, and cAMP signaling in the context of melanoma development, but reports no new findings.

This review presents evidence that correlations exist between hair mineral imbalances and various diseases, though inconsistencies in results highlight the need for standardized preparation methods.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

This study found that cortisone reductase deficiency is caused by inactivating mutations in the H6PD gene, affecting cortisol metabolism by preventing 11β-HSD1 enzyme function.

This study found that combining oral finasteride with topical minoxidil resulted in the greatest improvement in hair growth for male patients with androgenetic alopecia, compared to using any single treatment.

This review discusses the complex systemic nature of vitiligo and its associations with autoimmune conditions, emphasizing the need for increased understanding and awareness of related comorbidities and psychological effects.

This study found that human skin expresses proenkephalin, whose expression is upregulated by environmental stress and varies in pathological conditions, increasing in psoriasis and decreasing in melanocytic tumors.

This review discusses the use of Dermal Papilla cells as in vitro models for studying hair growth modulators, emphasizing their role in aiding the development of new hair treatments, but reports no new clinical results.

In this study, researchers found that depleting mtDNA in mice caused skin wrinkles and hair loss but restoring mitochondrial function reversed these effects, highlighting mtDNA's significant role in skin and hair health.

This study provides further evidence for a genetic basis of PCOS, showing that polycystic ovarian morphology is a marker of inherited biochemical features in families with PCOS.

This study observed that eliminating positional error in hair segment analysis can improve understanding of changes in isotopic composition, aiding the identification of pathological conditions and dietary patterns.

This review discusses the physiological skin changes during pregnancy and reports no new clinical results, emphasizing the importance of distinguishing these changes from pathological conditions.

This study found that short-chain fatty acids produced by the skin microbe Propionibacterium acnes may drive inflammatory gene expression in sebocytes, potentially contributing to acne.

This review discusses the role of keratins in maintaining epidermal structure and function and reports no new results; the authors emphasize the lack of rational therapies for skin disorders linked to keratin mutations.

The study reports that Fgf18 and Tgf-β2 signaling pathways in hair follicle stem cells have opposing effects on the timing of hair cycle transitions, influencing the shift from telogen to anagen phases.

Acne is caused by genetics, diet, hormones, and bacteria, with treatments not yet curative.

This review discusses the influence of oestrogens on various skin components and highlights their modulatory roles and receptor pathways, but it reports no new clinical results.

This study found that overexpression of the mineralocorticoid receptor in a mouse model led to premature epidermal barrier development, keratinocyte apoptosis, and postnatal alopecia, indicating new roles for MR signaling in skin physiology.

This review discusses diagnostic approaches for women with diffuse, nonscarring hair loss and reports no new clinical results.

This paper argues that the cycling hair follicle serves as a valuable model for systems biology research, highlighting its potential for translational medicine.

This chapter reviews the role of androgen receptors in mediating the actions of androgens in specific tissues and provides no new experimental findings.

This article reviews historical and recent developments related to toxic shock syndrome (TSS), emphasizing the increase in cases among young women using tampons, and calls for new research tools but does not report new results.

This review discusses the unique features of dermal white adipose tissue, its interaction with hair follicles, and its role in skin physiology, reporting no new experimental findings.

This review highlights the increasing clinical applications of high-frequency ultrasonography in dermatology, particularly for assessing the depth of skin tumors and monitoring inflammatory skin diseases, but reports no new clinical results.
