In this study on Drosophila wings, researchers identified 435 genes with significant expression changes during wing hair morphogenesis, and found new phenotypes for 9 genes through functional validation.

This article discusses the complexities of treating hair and scalp disorders in African American patients, emphasizing the importance of understanding their specific hair care practices and the unique impact on quality of life, but reports no new empirical findings.

This article reviews the characteristics and classification criteria of cutaneous lupus erythematosus and reports no new clinical findings.

This review discusses diagnostic challenges and management approaches for pediatric hair disorders, emphasizing the importance of distinguishing between acquired and congenital conditions, and reports no clinical results.

This paper reviews different types of hair shaft dysplasias and does not report any new clinical findings.

This article discusses the major role of motor vehicles in contributing to urban air pollution and its significant health impacts, especially in developing countries, but reports no new findings.

This review discusses potential cosmeceutical treatments for hair loss, including ingredients like procyanidins and isoflavones, but does not present new clinical outcomes; the authors highlight the promise of further research.

Human hair's structure makes it tough and resistant to breaking.

Terbinafine is more effective than itraconazole for toenail fungus, especially in older patients, and debridement improves its effectiveness.

This study found that papain/bisulfite disintegrates human hair cuticles by dissolving the endocuticle, potentially accelerated by ethanol's removal of cell membrane material.

This study identified significant differences in medullary structure, hair length, and root diameter among dorsal guard hairs of red foxes, golden jackals, and gray wolves in Turkey.

This study reports a mutation in the U2HR gene causing Marie Unna hereditary hypotrichosis in a Turkish family and notes eyebrow loss as a diagnostic clue.

This study identified 16 novel high sulfur KAP genes and two KAP pseudogenes on chromosome 21q23, showing expression in a specific region of the hair fiber cuticle.

This study identified a new type II cytokeratin, named K6hf, exclusively expressed in the companion layer of the human hair follicle, distinguishing it from other keratins and suggesting a unique biochemical role.

This article reviews the classification of hair shaft abnormalities, outlining their diagnostic features, but does not present new research findings.

This study identified a cluster of genes on chromosome 17 related to hair keratin-associated proteins, including 37 genes forming seven multigene families, localized in the hair shaft's upper cortex.

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 the evolution and ongoing debate about the causes of central centrifugal cicatricial alopecia in African American women, without presenting new clinical findings.

This study found that overexpression of Hoxc13 in GC13 mouse models affects hair follicle differentiation by interacting with medulla-specific genes, particularly Foxq1, suggesting a regulatory pathway for medulla differentiation.

In this study, researchers found that Asian hair contains more integral lipids than European or African hair, which may protect it better from UV-induced damage.

This review discusses the categorization of hair loss and increased hair density disorders related to systemic diseases and reports no clinical results, emphasizing the potential diagnostic value of history, physical examination, and histopathologic data.

This study used proteomic techniques to analyze human hair proteins, revealing keratin heterogeneity and identifying posttranslational modifications, such as cysteine trioxidation and methylation.

This article reviews the clinicopathologic features of short anagen syndrome in a child and suggests diagnostic methods like clinical examination and scalp hair growth rate measurement, without reporting new clinical results.

This study found that the moisture content of human hair significantly influences the type of fracture under tensile loading, with low or high humidity levels leading to smooth fractures and intermediate humidity resulting in step fractures.

This article discusses the use of cosmetic hair care products to improve patient satisfaction in hair loss treatment and reports no new clinical results; the authors emphasize complementing medical interventions with such products.

This study found that Merkel cell clusters require Frizzled6 signaling for their polarity information, while other hair follicle-associated structures align their orientation based on the hair follicle itself.

The review concludes that accurate diagnosis of different types of hair loss requires proper biopsy techniques and understanding the hair growth cycle and underlying causes.

This study shows that environmental contamination affects mummy hair, suggesting that using it to assess ancient people's health or nutrition should be approached cautiously.
