This article discusses chronic telogen effluvium in middle-aged women and reports no new clinical results; the authors note its abrupt onset and the distress it causes due to excessive hair shedding.

This review discusses three decades of progress in feather development, regeneration, and evolution, with no new experimental results; it highlights feathers' potential as a model for morphogenesis studies.

In this case-control study, researchers observed that women with female pattern hair loss exhibited significantly lower serum IGF-1 levels than controls, while IGFBP-3 levels showed no significant difference, suggesting a potential role for IGF-1 in the condition.

In this case report, a 3-year-old male with IFAP syndrome showed moderate improvement in skin symptoms and corneal erosions but no change in alopecia or photophobia after 6 months of acitretin therapy.

This study revealed that during avian skin development, complex tissue architecture results from specific cellular flows and mechanical processes that guide feather bud protrusion and elongation, with distinct differences noted in scale development, where rigidity restricts such transformations.

Bald men with male pattern baldness still have hair stem cells, but lack certain cells needed to grow hair.

In this report, a preterm neonate was found to have total irreversible hair loss due to congenital atrichia, confirmed by a mutation in the human hairless gene on chromosome 8p22, illustrating this rare autosomal recessive disorder.

This study examined different logistic damping effects in a chemotaxis system related to Alopecia Areata and found that certain conditions guarantee a unique, globally bounded classical solution, while others ensure a weak solution, offering new insights into preventing blow-ups in this context.

This study observed that intramuscular injection of sodium 131iodide at doses of up to 1 mCi can successfully induce hypothyroidism in rats without significantly damaging muscle or nearby tissues, despite concerns of adverse effects.

This report presents a case where a 17-year-old male developed severe unilateral alopecia following radiotherapy for pediatric glioblastoma multiforme, which did not respond to minoxidil or platelet-rich plasma treatments.

In this study, researchers established a mouse model for single follicular unit transplantation and reported successful integration and piloerection of transplanted hair follicles with surrounding host tissues.

A liquid protein diet caused hair loss in a young woman.

This study found that expression of certain mutant keratin genes in mice led to severe alopecia, suggesting a similar mechanism could cause hair loss in humans.

In this study, the researchers found that scalp hair follicles affected by female pattern hair loss are poorly vascularized, likely affecting nutrient delivery, but capable of nutrient uptake when supplemented.

This study found that the absence of the vitamin D receptor disrupts hair follicle structure during the first catagen in mice, linked to increased expression of the hairless gene.

This study found that Dkk4-knockout mice exhibited disrupted hair follicle patterning, including a lack of the first wave of hair follicles in the lateral back skin.

In this case report, a domestic shorthair cat with Trypanosoma evansi infection fully recovered after treatment with diminazene aceturate and supportive therapies, with no Trypanosoma detected in the blood following the treatment course.

This review identifies genetic mutations associated with congenital hair loss disorders in Japanese populations, particularly highlighting common LIPH gene mutations linked to woolly hair/hypotrichosis, and reports no new clinical results.

This study highlights alopecia areata incognita as a unique form of alopecia areata that shares features with telogen effluvium and may relate to androgenetic alopecia, noting its sudden onset and favorable response to topical steroids.

In this study, researchers found that the KLHL24-ΔN28 protein variant disrupts hair follicle stem cells in a mouse model, leading to premature hair loss by degrading keratin 15.

This study found that follicular unit-like wigs made from xenogeneic human hair and medical polypropylene exhibited good histocompatibility, a low loss rate, and satisfactory appearance one year after transplantation in rabbits.

In this study, NIH hairless mice showed increased susceptibility to Listeria monocytogenes infection compared to NIH mice, potentially due to differences in gut microbiota and monocyte levels.

This study found that women with female pattern hair loss had significantly lower serum IGF-1 levels compared to controls, but no significant association between IGFBP-3 levels and hair loss severity was observed.

This case report describes a rare instance of thymoma associated with alopecia areata in a 60-year-old woman who had no signs of myasthenia gravis, highlighting the need for thoracic surgeons to consider alopecia in such cases due to its impact on quality of life.

This study found that Acvr1b signaling is crucial for both hair follicle development and cycling in mice, with the genetic disruption leading to hair loss and a thickened epidermis.

This study in mice found that MEIS2 expression in mesenchymal dermal cells is crucial for the formation of whiskers and the initial steps of epithelial placode development, independently of sensory nerve innervation or Foxd1 expression.

This study found that mutations in type I IRS keratin genes disrupt keratin protein complexes in mice, suggesting crucial roles for these genes in proper hair coat formation.
