This study describes the effects of adrenocorticotropic hormone injections in rats, specifically detailing their stunted body growth and changes in visceral proportions and hematology.

This study demonstrated radiocalcium uptake in skin, eye, cartilage, and mucous glands, with the highest concentration in the hair follicle's keratogenous zone.

Terrestrial vertebrates have balanced keratin gene clusters, unlike teleost fish.

This case report describes a 23-year-old woman with a history of ambiguous genitalia and complex medical conditions, including a pelvic mass and hirsutism, observed from childhood to adulthood.

This study reported common skin changes and symptoms associated with thyroid disorders, such as dry skin in hypothyroidism and warm, soft skin in hyperthyroidism, and noted urticaria as a frequent autoimmune association in hypothyroid patients.

Thorough clinical examination is crucial for diagnosing unusual alopecia.

In this study, researchers explored the molecular and cellular traits of avian reticulate scales, finding that they lack localized stem cell niches for regeneration, unlike other scale types, leading to repair but not regeneration after wounding.

This review discusses common skin appendage diseases, including their pathophysiology and treatments, but does not report new results.

This study found that patients with thyroid dysfunction were more likely to experience skin disorders such as chronic idiopathic urticaria, vitiligo, and alopecia areata compared to a control group.

This letter to the editor discusses the occurrence of alopecia areata, thyroiditis, and vitiligo in a Japanese patient with smoldering type adult T-cell leukemia/lymphoma, but it reports no new research findings.

An elderly woman's swollen, painful foot was found to be caused by a rare type of bone lymphoma, which improved with radiation treatment.

This article presents a case of an 8-year-old boy with Recklinghausen's disease showing features such as café-au-lait spots, alopecia, and developmental anomalies, but reports no new findings beyond observation.

In this study, researchers discovered a honeycomb-like structure in the skin of spiny mice that facilitates tissue shedding and regeneration, attributed to a uniquely arranged collagen VI and influenced by spiny hair development.

This study suggests that chicken and alligator scales evolved independently through convergent evolution rather than sharing a common origin with avian feathers.

Human hair follicles have their own thyroid hormone system.

The skin is the body's largest organ, with layers, cells, and structures that protect and support it.

This study examined the complex morphology of the cornified claw sheath in domesticated cats, uncovering structures and growth patterns that help maintain sharp claw tips essential for climbing and prey capture.

This article reviews the skin, hair, nail, and mucosal changes linked to various pediatric endocrine disorders but provides no new clinical findings.

This study found that alopecia areata can affect individuals across various ages but is predominantly observed in males aged 21-40, and may be linked to autoimmune diseases, thyroid issues, and inflammation.

This study demonstrated how cellular flows and tissue mechanics guide the topological transformations in avian skin, essential for feather follicle development from scales.

In this study, JAK inhibitors for treating alopecia areata and atopic dermatitis were generally well tolerated in a real-world setting, with most adverse events being mild or moderate and rare serious cases resembling the general population incidence.

This case report describes a unique lesion in a 10-month-old girl, characterized by increased eccrine glands and hair follicles, leading to the proposed term "hybrid eccrine gland and hair follicle hamartoma".

This review discusses various diseases associated with hidradenitis suppurativa, including obesity, arthritis, and pyoderma gangrenosum, but reports no new clinical results and calls for further research.

This study indicated that abnormal Bmp signaling in β-catenin gain-of-function mutants is associated with anorectal malformations, shedding light on potential mechanisms underlying these congenital conditions.

This study identified a 195 bp duplication in crested chickens that causes large crest feathers and can be associated with cerebral hernia in some breeds, but not all.

This research found that Leydig cells significantly rely on synthesizing omega-6 HUFAs to support male steroid hormone production, highlighting a new role for these fatty acids in the male reproductive system.

This study found that intramuscular injections of a PRP-derivative in healthy beagle dogs did not result in statistically significant changes in lumbar muscle tissue or IGF-1 blood concentration, suggesting the treatment may be safe at therapeutic doses.

In this review, extensive analysis using conditional mutant mice revealed that androgen and Wnt signals play crucial roles in the development and function of male external genitalia and erectile tissue, while also exploring various regulatory factors involved in their pathogenesis.

Transgender women have similar fitness to cisgender women, while transgender men have higher fat and lower strength than cisgender men; hormone therapy affects body composition and strength.
