This study found that Prss53-mutated rabbits exhibited curved hair and skeletal dyskinesia, suggesting a link between Prss53 loss and these traits, potentially involving disrupted calcium metabolism.

In this study, researchers concluded that hereditary 1,25-dihydroxyvitamin D-resistant rickets, characterized by specific mutations in the vitamin D receptor gene, may resolve metabolic abnormalities with age, though associated alopecia remains.

This study suggests that a newly identified KRT 71 gene variant may be responsible for curly hair in Curly Coated Retrievers and potentially contributes to follicular dysplasia.

Collagen VII helps skin heal and stay strong, sirolimus may lower skin cancer risk in kidney transplant patients, high-molecular-mass hyaluronan helps naked mole rats resist cancer, dermal γδ T cells aid in hair growth in rodents, and overexpression of IL-33 in mouse skin causes itchiness, offering a model for studying allergic inflammation treatments.

This systematic review assessed the off-label use of topical Ruxolitinib cream for various skin conditions and found it effective for lichenoid and granulomatous dermatoses, though results for alopecia areata were inconsistent. The authors indicate that further research is warranted to confirm these findings.

Pityriasis rubra pilaris is a rare skin disorder with reddish-orange patches and thickened skin, needing better treatment understanding.

This study found that wolves in heavily hunted areas of Canada's tundra–taiga exhibited higher levels of stress and reproductive hormones, indicating social instability and increased reproductive effort due to human-caused mortality.

This study by Gao et al. reports that two nonsteroidal selective androgen receptor modulators, S1 and S4, demonstrated tissue-selective actions in rats, suppressing prostate growth while maintaining muscle growth without altering hormone levels.

This article reviews the dermabrasion resurfacing technique and details consultation, medication, management practices, and expected outcomes, but it does not present any new clinical data.

In this reported case, a 50-year-old man developed an acneiform rash, a common skin side effect of EGFR inhibitor therapy, after starting lapatinib for breast cancer; treatment with doxycycline and hydrocortisone cream led to significant improvement within one week.

This case report details a 21-year-old woman with dermatopathia pigmentosa reticularis, presenting with generalized reticulate hyperpigmentation, diffuse noncicatricial alopecia, onychodystrophy, palmoplantar keratoderma, and poorly developed dermatoglyphics.

This study explores the role of cell competition in maintaining genomic quality in epidermal stem cells and proposes that this process might influence cancer development in skin tissues.

This study suggests that variations in α-keratin proteins influence the structure and characteristics of wool fibers, indicating that keratin genes could serve as useful markers for identifying different wool traits.

In this study, Dodatek A operationalizes the Functional Androgen Axis framework by defining three system-level indices and an efficiency metric to describe androgen function, incorporating key methodological improvements and acknowledging significant limitations for future empirical validation.

This study found that Ajuga reptans leaf and root extracts, when incorporated into cosmetic products, improved skin hydration, elasticity, pore size, hyperpigmentation, and wrinkle depth.

This study in Gansu alpine fine-wool sheep identified two SNPs in the KRT71 gene that significantly affect wool length, with distinct expression patterns observed in hair follicles, suggesting KRT71 as a candidate gene for enhancing wool production traits.

This research suggests that the barley protein RACB supports cell polarity functions rather than interfering with immunity, as it aids nucleus positioning during fungal attack rather than affecting early immune responses.

This study explored the effectiveness of the oral JAK1/2 inhibitor ruxolitinib in treating patients with moderate-to-severe alopecia areata, building on prior success with JAK inhibitors in mice, but results are not reported in this abstract.

This study found that nuclear androgen receptor expression was enhanced by dihydrotestosterone in rat gubernacular mesenchyme, but this did not affect muscle morphology or matrix composition during fetal development.

This study found that temperature significantly affects the mechanical properties of rabbit hair fibers, with increased tensile strain and decreased breaking strength in humid conditions.

This study reported that gels containing methyl cellulose exhibited the highest consistency factor and optimal homogeneity compared to those made with hydroxypropyl cellulose or its combination with pullulan, indicating the significant impact of gelling agents on gel properties.

This case study reported that absence of alopecia does not reliably predict responsiveness to vitamin D treatment in Vitamin D-dependent rickets type II, as demonstrated by a patient with normal hair growth who showed extreme resistance.

TEDAR is crucial for skin cell differentiation and barrier formation.

This study found that RXRα/RARγ heterodimers are necessary for retinoic acid-induced keratinocyte proliferation in the skin, while normal epidermal maintenance does not require RAR-mediated signaling.

This study reported a case of hereditary vitamin D–resistant rickets caused by a single heterozygous missense mutation in the VDR gene, showing dominant-negative effects and reduced response to 1,25-dihydroxyvitamin D3.

This review discusses nonsteroidal selective androgen receptor modulators and their potential therapeutic applications but reports no new clinical findings.

This study investigated how vitamin A deficiency, certain diseases, and pregnancy affect cattle coat hair structure, finding notable keratin fibril interference under vitamin A deficiency and structural modifications in chronic renal failure, while pregnant cows exhibited superior hair tensile strength compared to non-pregnant ones.

In this study, researchers found that replacing natural aggregates with animal bones and human hair with increased microroughness may improve the mechanical strength and durability of concrete.

This study used Raman spectroscopy and wide-angle X-ray scattering to observe two main α-helix to β-sheet transitions in hair keratin under varying humidity levels, finding that water impacts when these structural changes occur, involving a disordered state.

This study suggests that increased amounts of less stable disulfide conformers in hair shafts may be linked to the brittleness observed in trichothiodystrophy.
