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 case study highlights the importance of considering broad causes when evaluating hot flashes in middle-aged men, as it detailed a pituitary macroadenoma causing secondary hypogonadism in a man presenting with such symptoms.

This article describes the structure and components of hair cuticle cells and their intercellular junctions but reports no new clinical results.

This clinical case report identifies xanthomatous hypophysitis in a male patient, highlighting the mismatch between clinical symptoms and MRI findings, which led to a pituitary biopsy and accurate diagnosis instead of unnecessary surgery.

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 observed significant clinical effects, such as hair loss and testicular changes, in common quail treated with the steroids IVF-C Inj and Diane-35, especially highlighting cyproterone acetate's impact on vital organs like the liver.

This study found that normal human epidermis expresses TSH and may be an indirect target of TSH signaling, with expression regulated by endocrine controls of the hypothalamic-pituitary-thyroid axis.

This review discusses the structure and assembly of the cornified cell envelope in stratified squamous epithelial cells and various disorders leading to barrier defects, but reports no new findings.

This study observed that TBX3 mRNA expression levels were region-specific and correlated with pigmentation patterns in dun Mongolian horses, providing insights into the genetic mechanisms behind their distinctive Bider markings.

This study, conducted on 17 dogs with hyperadrenocorticism in Germany, concluded that while common symptoms like polyuria and polydipsia were observed in all cases, clinical signs and blood parameters did not significantly correlate with diagnostic test results for the condition.

This study shows that microdiffraction experiments reveal structural layers in keratinous tissues, each with different keratin types, potentially explaining their dual role as mechanical support and chemical barriers.

The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.

This study found that the differential expression of α- and β-keratin genes in feathers may explain their morphological and structural diversity, highlighting the chicken as a model for studying keratin-related diseases.

This study found that examining the microscopic and ultramicroscopic structures of donkey and horse hair can help differentiate between the species based on distinct differences in hair cuticle and brain substance patterns.

This study found that CD1d is strongly expressed in human scalp skin and hair follicles, particularly in the anagen phase, suggesting a role in scalp immunology and potential implications for hair disorder treatment.

This review discusses new developments in understanding the structure and properties of keratin fiber cell membrane complexes, without reporting new experimental results.

In this study, rabbit esophageal epithelial cells were found to produce K4 and K13 keratins in suprabasal cells, forming disulfide-crosslinked dimers that may support the physical stability of the esophageal lining.

This case study reports the clinical features of triple H syndrome in a 25-year-old man, including ACTH deficiency, alopecia universalis, and anterograde amnesia, which were improved with hydrocortisone treatment.

This study revealed that frizzled 3 can fully rescue polarity defects in frizzled 6-null mice, while frizzled 6 can partially rescue defects in frizzled 3-null mice, highlighting conserved signaling roles in these proteins.

This study suggests that distinct chromatin topologies allow different lineage-specific enhancers to regulate Hoxd genes in mouse vibrissae and chicken feather primordia, while conserved regulatory elements maintain transcriptional robustness in the embryonic trunk across species.

This study observed that dandruff is linked to a weakened immunoprivilege in hair follicles, with reduced Langerhans cells and increased epidermal CD4+ and CD8+ T cell infiltration.

In this study, researchers reported telocytes in the dermis of silky fowl embryos at different developmental stages, highlighting their immunophenotypes and interactions with other cells.

This review discusses the complication of vitiligo in patients undergoing diphencyprone sensitization therapy for alopecia universalis and reports no new clinical findings.

This study found that increased Bcl-2 protein expression after DPCP treatment was associated with hair regrowth in alopecia areata patients, suggesting its role in inhibiting apoptosis.

This abstract pertains to a dermatology-related academic profile without reporting any specific study findings. Results or research details are not provided.

This case report describes a 36-year-old female patient with panhypopituitarism, experiencing severe adrenal insufficiency and thyroid hormone deficiency, which led to electrolyte imbalance, QT interval prolongation, and ventricular tachycardia; treatment stabilized her condition, underscoring the importance of hormonal evaluation in arrhythmia assessment.

In this study, researchers discovered that the MafB gene, which is important for macrophage differentiation, shows high expression in the pancreas and is influenced by sex steroids, with varied expression patterns in hamster tissues and during reproductive phases.

Canine skin has two main layers: the epidermis and dermis, with a supportive subcutis layer.

This study reported that the coat hairs of golden takin, living in harsh environments, have unique structural features compared to cattle, with overcoat hairs having continuous medullated tissue and undercoat hairs being finely crimped, potentially contributing to temperature regulation in cold conditions.
