This study investigated the mechanism responsible for pili torti formation in Björnstad syndrome using a transmission electron microscope, but did not establish a definitive explanation.

This study identified TSC2 as an important regulator of hair follicle morphogenesis and patterning, with Tsc2cKO mice showing altered hair patterns and frequencies compared to controls.

This study investigated the interdigital glands in sheep, highlighting their apocrine sweat glands' ultrastructural characteristics and positive lectin reaction, but reported no new clinical results.

This review discusses the use of trichoscopy for diagnosing alopecia and reports no new clinical results, emphasizing its role in identifying vascular and follicular features.

This case study reports that a heterozygous missense GJA1 mutation, p.Gly138Ser, in a 2-year-old boy with oculodentodigital syndrome primarily resulted in syndactyly, fifth finger hypoplasia, and hypotrichosis, without neurological or craniofacial abnormalities.

This study examined 16 sporadic trichoblastic tumors and found that although one showed malignant transformation, clinical follow-up revealed no residual or metastatic disease. RNA sequencing indicated a high tumor mutational burden and absence of a UV-related signature, helping to distinguish these tumors from similar growths.

This study found that concentrated clusters of noradrenergic nerve fibers form a longitudinal linear system in rat skin, particularly innervating arrector pili muscles.

This case report describes a rare instance of trichotillomania, tricophagia, and a gastric trichobezoar in an 11-year-old boy, emphasizing the importance of a multidisciplinary approach involving surgery and psychiatric evaluation to address this uncommon psychiatric disorder.

This study examines the structure of the "sinuskissen" in cat hair follicles, revealing it as a loose connective tissue susceptible to changes in aqueous flow, and describes its variable three-dimensional shapes.

This chapter reviews trichoscopic criteria and diagnostic features for various hair and scalp conditions, emphasizing their utility in non-invasive diagnosis, but reports no new clinical results.

This study reported that the PTGER2 gene is strongly expressed in cashmere goat skin and its expression tends to decrease from the anagen to telogen stages of the hair follicle cycle.

This study compared trichostasis spinulosa with keratosis pilaris and eruptive vellus hair cysts, finding differences in lesion distribution and microscopic appearance.

This study reported that prompt hair removal effectively treated hair tourniquet syndrome in infants, with all patients healing without complications.

This study found that Notch-related genes, including Notch1 and Notch2, and their ligands and regulators, have distinct patterns of expression during mouse hair vibrissa follicle development and the adult hair cycle.

This study investigated transcription factors in human trophectoderm cells during development, finding that GATA2 and GATA3 are essential for transforming stem cells into induced trophoblast stem cells, which display characteristics similar to placental progenitor cells, offering new methods for modeling placental-associated diseases.

In this study, researchers identified elongated corkscrew hairs as a new trichoscopic pattern in immunosuppressed adults with chronic endothrix tinea capitis, which may help in earlier diagnosis and targeted mycological investigation.

This study reports that a novel frameshift mutation in the HTRA1 gene in a CARASIL pedigree led to reduced HTRA1 protein and increased TGF-β1 expression, potentially causing severe CARASIL and peripheral small arterial disease.

This case report identifies a novel mutation in a patient with trichorhinophalangeal syndrome 1 and reduced TRPS 1 protein expression in hair follicle tissues compared to normal subjects.

This study describes the anatomy of arrector pili muscles in scalp hair follicular units, proposing a model where a single muscle structure is shared by all follicles within a unit.

This study observed that multiple familial trichoepitheliomas commonly presented with a cribriform histopathological tumor pattern, differentiating them from solitary trichoepitheliomas.

This case study suggests that early or significant alopecia in young adults may warrant investigation for underlying congenital conditions like trichorhinophalangeal syndrome.

This study suggests that GATA6 is a key regulator of the upper pilo-sebaceous unit homeostasis and differentiation in human skin.

This study examined the unique structural features of sinus hair follicles in the shrew Sorex unguiculatus, which suggest a specialization for vibration sensing.

This study characterized the mouse profilaggrin gene, finding it structurally identical to its human counterpart, and noted differences in protein-coding regions that could impact epidermal differentiation.

This study explored the structure and keratin composition of marsupial hairs, finding similarities in keratin localization to hairs in placental mammals, and highlighting potential roles of trichohyalin and transglutaminase during hair development and shedding.

This study found that using a trapezoid strip in hair transplantation for androgenetic alopecia minimizes follicular unit transection and yields significantly more grafts compared to an elliptical strip.

In this study, full-thickness wounding on Lanyu pigs led to scar formation and disrupted cell markers, while partial-thickness wounding allowed limited regeneration of rete ridges and papillary dermis.

This study found that trichorrhexis nodosa, a cause of unexplained hair loss, is often linked to mechanical trauma rather than a metabolic defect.

A rare benign skin tumor showed unusual features of sebaceous and sweat glands, important for correct diagnosis.
