This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

JAK inhibitors might help treat alopecia areata.

This abstract provides no results or study findings; it only includes author affiliations and general commentary.

This chapter reviews various types of alopecia and associated skin diseases in dogs and cats but presents no new clinical findings.

This study identified a new mutation in SELH/Bc mice causing distinctive whisker and body hair abnormalities, mapped near the type I keratin cluster on chromosome 11.

This study reports the first identification of the deleterious NIPAL 4 variant, associated with autosomal recessive congenital ichthyosis, in an American Bully and describes its clinical management and follow-up.

This study reported that knocking out the HR gene in pigs using CRISPR/Cas9 led to hairless eyelids and abnormalities in the thymus and peripheral blood, suggesting pigs as a model for human HR-related hair disorders.

This study compared JAK inhibitors for moderate-to-severe alopecia areata and found brepocitinib 30mg and deuruxolitinib 12mg to be most effective, though deuruxolitinib may cause more adverse events. Further research is needed for long-term efficacy and safety.

JAK inhibitors effectively regrow hair in alopecia areata but hair loss often returns after stopping treatment.

Deuruxolitinib effectively promotes hair regrowth in alopecia areata.

This study found that in eyelids with ptosis, voluntary brow elevation raises the eyelid position similar to maximal eyelid opening, suggesting brow lifting is driven by efforts to elevate the eyelid.

In this report, the researchers described a follicular dysplastic syndrome in two adult white-tailed deer, where gross alopecia and histologic signs suggestive of alopecia areata were observed, potentially predisposing affected deer to environmental exposure.

Doctors successfully rebuilt a sideburn using skin and hair from near the ear in one surgery.

This study found that the systemic wrinkled skin phenotype in Xiang pigs involves gene expression changes and genetic variations associated with oxidative stress and extracellular matrix components, resembling features seen in Shar-Pei dogs.

In this study, researchers developed a mathematical model of outer hair cell hair bundles that replicates experimental responses to mechanical stimuli, providing insights into the stimulus-dependent adaptation mechanisms and the functional significance of their three-row stereocilia configuration in mammalian hearing.

In this study, a 13-year-old boy developed temporary pressure alopecia from wearing orthodontic headgear, which resolved after discontinuation, highlighting a rare side effect that can affect psychosocial wellbeing.

This chapter outlines eyebrow aging and aesthetics and describes a five-step approach using neurotoxin and filler synergy to enhance eyebrow appearance, but reports no new clinical results.

This study found that scalp medical tattooing effectively improved cosmetic appearance and concealed bifid parietal whorls without complications in the patients evaluated.

In this study, transiently activating the sonic hedgehog signaling pathway in chickens transformed reticulate scales on the feet into feathers comparable to body feathers, without ongoing treatment, suggesting this pathway affects the diversity of bird skin appendages.

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 case report describes a unique occurrence of plica polonica in a lung adenocarcinoma patient on chemotherapy, linked to anagen effluvium from paclitaxel and carboplatin and uncustomary shampoo use.

This study found that human mesenchymal stem cells overexpressing JAM-A improved hair follicle structure and hair formation in mice by reducing abnormalities such as curved and zigzagged follicles.

This letter to the editor reports an observation of alopecia occurring after treatment with deoxycholic acid for reducing submental fat, but it presents no new clinical data or broader conclusions.

In this research, the authors reported that long-term treatment with the JAK1/JAK2 inhibitor baricitinib effectively maintains hair regrowth in patients with severe alopecia areata and may gradually improve outcomes for partial responders over 104 weeks, without increasing side effect incidence.

This case study reported a 34-year-old woman presenting with secondary amenorrhea, hirsutism, and obesity showed elevated testosterone and anti-Müllerian hormone levels, leading to the exclusion of nonclassical congenital adrenal hyperplasia as a diagnosis.

This review discusses available microsurgical reconstructive options for craniofacial surgery and reports no new clinical results; it highlights how innovations in the field have advanced reconstruction techniques.

This study found that the combination of epidermal growth factor and Jagged1 significantly stimulated hair growth in mice with androgen-suppressed conditions, suggesting potential therapeutic implications for androgenetic alopecia.
