This article reviews the importance of quality control and quality assurance in hair transplant practice and emphasizes their potential to improve procedural outcomes, yet it reports no new clinical data.

This study found that visual hair density is better correlated with hair count and shaft diameter, leading to the development of the Hair Diameter Index used in planning hair restoration procedures.

This study found that the expression of CK 15 and CK 19 in vitiligo patients undergoing phototherapy was correlated with improved repigmentation, suggesting their potential as markers for stem cell stimulation.

This study found that pediatric HSCT recipients, especially those with chronic graft-versus-host disease, are at risk for developing various nonmalignant late cutaneous changes such as vitiligo, psoriasis, alopecia, and nail changes.

This study observed that knocking out the 1α-hydroxylase gene in mice resulted in rickets and growth retardation, demonstrating the enzyme's crucial role in vitamin D function in animals.

This study identified 53 keratins in the yak genome, predicting diverse phosphorylation sites and subcellular localizations, and highlighted strong gene expression correlations during the yak hair follicle development cycle.

This study introduced a volar skin excisional wound model that closely mirrors human wound healing and supports evaluation of skin regeneration with multiple appendages and innervation.

In this study, transfection experiments showed that mutations in the K85 gene affect filament formation with K35, which may impact hair formation related to ectodermal dysplasia.

This study developed and tested a new injectable hydrogel for chronic diabetic wounds, reporting significant improvements in wound healing through enhanced angiogenesis, epithelization, and reduction of inflammation and infection in animal models.

This study reports a novel missense mutation in the HR gene in a 68-year-old Hungarian woman with alopecia universalis and limb deformities, suggesting a need for further research on its role in these conditions.

This study found that in a mouse model with hereditary 1,25-dihydroxyvitamin D resistant rickets, a mutant vitamin D receptor lacking hormone-binding ability could restore normal hair cycling and affect parathyroid hormone regulation.

Human hair keratin genes hHa2 and hHb1 are located on chromosomes 17 and 12.

This study presents computational modeling and experimental analysis of the HGT protein KAP8.1, identifying key structural features that may influence hair's response to environmental conditions.

A genetic mutation caused severe rickets and alopecia in an Indian patient, but high-dose calcium and phosphate treatment improved their condition.

This study found that preventing abnormal mineral ion homeostasis in vitamin D receptor knockout mice stopped bone abnormalities, while the animal's skin phenotype arose from direct receptor effects independent of vitamin D.

This study found that lentiviral vector tropism in three-dimensional skin tissue is distinct from keratinocytes in culture and is influenced by complex extracellular interactions.

This article reports a rare case of toxic keratitis in a patient due to excessive intake of vitamin A, highlighting hypervitaminosis A risks such as severe eye conditions and systemic health issues, especially with cumulative doses exceeding therapeutic levels.

This source suggests that the metaverse could play a crucial role in dermatology by offering new ways to manage chronic skin conditions and improve patient support and education, especially for those hesitant to seek in-person consultations.

This study highlights a rare case of vitamin D-dependent rickets type 2A caused by a heterozygous mutation in the vitamin D receptor gene, emphasizing the complexity of managing this condition with high-dose calcium and vitamin D therapy.

This study identified nine novel KRTAP5 family genes associated with human hair formation, demonstrating preferential expression in hair roots and suggesting their role in hair development.

This study identified a mutation hotspot in the caracul (Ca) locus of mice, implicating the mK6irs1/Krt2-6g gene in hair formation and potentially human hair and skin diseases.

In this study, keratin genes mHa1 and mHb4 were unable to form an extensive keratin network in one cell line, altering endogenous keratin distribution, but showed better integration in another cell line.

This report describes a case of widespread Porokeratotic eccrine and hair follicle nevus in a 15-year-old woman with keratitis-ichthyosis-deafness syndrome, involving both eccrine ostia and hair follicle infundibula.

This study found that VDR knockout mice exhibited muscle and motor impairments affecting locomotor behavior, while cognitive functions such as exploration, working memory, and anxiety appeared unaffected.

This case report suggests that Kawasaki disease should be considered in the differential diagnosis for children presenting with alopecia following a febrile illness with mucositis and conjunctivitis.

This study characterized a new human keratin, hK6irs1, specifically found in the inner root sheath of hair follicles, which suggests its role in the structural integrity and guidance of growing hair shafts.

KLHL24-mutant stem cells help understand skin and heart disease.
