This study describes the structure and composition of the epidermal horny layer in elephant seals, noting that its keratinized cells are attached without a specialized fission zone, differing from the sloughing mechanism in reptiles.

This case report describes a 43-year-old woman with achalasia, pangastritis, and hyperthyroidism, highlighting the rare association between achalasia and autoimmune conditions like hyperthyroidism.

This review discusses the roles of filaggrin and trichohyalin in keratinocyte differentiation and reports no new results; the authors introduce possible hybrid granules in tongue epithelia.

This study found that diphencyprone is an effective and safe treatment for extensive alopecia areata, especially with long-term therapy and maintenance to reduce relapse risk.

This study found that feather patterning is primarily self-organizing and dynamic, relying on both genetic and epigenetic controls, with implications for similar processes like fingerprints and pigmentation.

This study identified distinct gene expression programs in keratinocytes responsible for forming hard scales and soft interscale epidermis in chickens, revealing conserved differentiation genes similar to those in human skin.

This review discusses the role of adipose tissue as an endocrine organ affecting skin physiology and suggests a complex interaction between adipocytes and the skin as part of the broader endocrine system, but provides no new clinical results.

This study found that forming inclusion complexes of DPCP with HPβCD using the 3D ground mixture method enhances its anti-inflammatory activity at lower doses compared to complexes with β-CD.

This review synthesizes current knowledge on choriogenesis, the final stage of oogenesis in insects, by exploring the role of follicle cells, regulatory mechanisms of gene expression, and the biochemical makeup of the eggshell, while also highlighting structural diversity and adaptations across insect species.

This study found that differentiated cells of the corneal epithelium can be converted to hair and interfollicular epidermis through a multistep process involving dermal developmental signals.

This article discusses the role of human scalp hair follicles in neurohormone production and their model potential for studying neuroendocrine signaling, reporting no experimental results.

This review explores theories on the evolution of hair from synapsid scales and glands, proposing mechanisms supported by comparative studies, but reports no new experimental findings.

Cornification evolved from keratinization in vertebrates, with differences between mammals and sauropsids.

This animal study observed that while topical MBEH and intraperitoneal phenol induced hair graying in eumelanic mice, they had little effect on pheomelanic mice, and amcinonide reduced certain epidermal melanocytes in both.

In this study, researchers found that Dlx3 plays a crucial role in regulating chromatin accessibility and gene transcription during keratinocyte differentiation in the epidermis, highlighting its potential impact on epidermal barrier formation and differentiation.

This study reported that a 12-year-old neutered male Siberian husky dog showed resolution of alopecia, pyoderma, and diarrhoea after thyroidectomy and thyroid supplementation for a functional thyroid carcinoma.

In this study, pair housing of rhesus macaques after intrafacility transfer reduced some undesirable behaviors and diarrhea compared to single housing, although no cortisol level differences were observed.

In this study, feeding H-line chickens a diet with 1.0% tyrosine for 40 days significantly increased melanin deposition in feathers and revealed changes in gene expression related to melanin pathways, suggesting tyrosine's involvement in regulating feather color through the EDNRB2 regulatory network.

This abstract provides funding and institutional support information but reports no new research findings.

This review discusses the cornification process of epidermal keratinocytes in forming the skin barrier and reports no new results; it emphasizes the importance for diagnosis and treatment of skin disorders.

This study detailed the structure and amino acid composition of sheep trichohyalin, noting its presence in various tissues and suggesting a possible functional role beyond structural support in hair follicles.

This study found that the corneal epithelium differentiation program can proceed independently of lens formation, suggesting the corneal program is the default in eye development.

A woman experienced fluctuating thyroid conditions and eye disease, but her symptoms improved with treatment.

This study found that the cytoplasmic dynein component Dynlt3 is essential for effective melanosome transport and transfer in mouse melanocytes, linking melanosome positioning and acidity to the Wnt/β-catenin signaling pathway.

This review discusses how ophthalmic findings can reveal key endocrine disorders and reports no new clinical results, emphasizing the eye's role in diagnosing and managing systemic diseases like diabetes and Graves' ophthalmopathy.

This essay reviews the role of human scalp hair follicles in the "brain-skin connection," highlighting their dual function as targets and sources of neurohormones, without reporting new experimental results.

In this study, researchers observed monochorionic diamniotic twins with discordant clinical phenotypes, where one had high-grade trisomy 12p mosaicism in certain tissues, while the other showed confined mosaicism likely due to twin-to-twin transfusion.

This study presents the first detailed 3D models of the complete K1/K10 keratin dimer and identifies structural features and interactions that may inform understanding of keratin filament assembly.

This study observed that insulin-dependent diabetes induces specific molecular changes in the keratin structure of hair, potentially offering a new way to study diabetic complications through easily accessible tissues.
