In this study, researchers characterized the FGF5 gene in Chinese Merino sheep, identified a new mRNA splicing variant, FGF5S, and noted its restricted expression in the brain, spleen, and skin.

This study demonstrates that (9+2) topological patterns derived from fractal fiber sets exist, with nine total patterns and only two being independent or fundamental.

Animal hair fibers like wool and mohair are strong when dry, but vicuna fibers are very brittle.

This study indicates that sheep prenatally androgenized with testosterone show wool fiber diameter changes that parallel the increased hair diameter in women with polycystic ovary syndrome.

This study found that epidermal growth factor significantly reduced fibre growth in cultured Tukidale and Romney hair follicles, while cortisol had no effect on follicle growth.

This review discusses hair shaft disorders, noting the lack of specific treatments and recommending general care practices to prevent hair damage, with some improvement possible during puberty or with treatments like minoxidil.

This review examines genetic variation in the ovine KRTAP1.1 gene and its potential impact on wool quality, reporting no new findings but suggesting opportunities for developing gene markers for wool and pelt traits.

This study demonstrates a sample preparation method for wool follicles that allows for clear keratin labeling and ultrastructural preservation in microscopy, reducing common artefacts from conventional fixation techniques.

This article reviews hair growth and loss in children and offers diagnostic approaches, reporting no new results.

Genetic mutations cause various hair diseases, and whole genome sequencing may reveal more about these conditions.

Normal hair thickness varies by scalp area and a mix of hair thicknesses is typical in healthy individuals.

Researchers developed a method to identify and measure different animal hair fibers in textiles, successfully distinguishing materials like cashmere from cheaper fibers.

This study reports that hair fibers degrade most in acidic sandy clay, while silicone oil treatment is effective for conserving various hair types and artifacts.

This study analyzed inner root sheath-specific genes in Tan sheep during various growth stages, finding peak expression at birth. The pattern of genes KRT71, KRT72, and TCHH is consistent with wool crimp, potentially influencing wool morphology.

This study identified a primitive coarse wool characteristic in Merino sheep that enhances environmental adaptability and fine wool yield without reducing quality, suggesting that epigenetic mechanisms, particularly involving the imprinted Gtl2-miRNAs locus, regulate this advantageous trait.

In this study, researchers successfully cloned the KAP24.1 gene from sheep to analyze its expression in skin and hair follicles, finding that Mountain-type Hetian sheep showed the highest levels of expression and that androgen concentration significantly influenced KAP24.1 protein expression.

This biographical abstract highlights George Rogers' pioneering contributions to the understanding of keratin molecular structure and keratinisation biochemistry, including the application of electron microscopy to hair ultrastructure and the discovery of enzymes and gene transcription processes relevant to keratin proteins.

This study found that short-day photoperiod treatment in Shanbei white cashmere goats enhanced cashmere growth, increased secondary follicle density, and altered hormone levels and gene expression related to hair follicle development.

This study found that taurine dietary supplementation could reduce lipid metabolism, enhance antioxidant capacity, and improve hormone levels in Angora rabbits, with 0.2% taurine increasing wool production.

This study found that exposure to red LED light may improve fibre quality and hair follicle development in Angora rabbits, potentially due to increased melatonin secretion.

This chapter reviews the clinical features and diagnostic information for various skin diseases in sheep but reports no new research results.

This educational activity reports no new research findings; it aims to help physicians assess and improve their clinical skills through self-evaluation and continued medical education.

In this review, researchers highlighted the prevalence of hereditary hair diseases in the Japanese population, emphasizing the significant impact of LIPH gene variants on autosomal recessive woolly hair and the importance of continued research to better diagnose and manage these disorders.

In this study, the ablation of Tet2/Tet3 genes in mouse skin epithelial cells led to altered hair shape and length, highlighting their role in regulating hair follicle gene expression and chromatin structure.

This study reports that hypotrichosis congenita in Hereford cattle is associated with a KRT71 mutation, leading to color dilution follicular dysplasia.

This chapter reviews the clinical and morphological diagnostic features of various hair dysplasias, including atypical pili torti, pseudomonilethrix, and trichothiodystrophy, and reports no new results.

This collection of case reports discusses various rare dermatological conditions, including alopecia totalis with amyloidosis and multiple myeloma, and provides descriptive insights without reporting new clinical findings.

This study found that sheep possess a polymorphic KAP8-2 gene that shares high sequence identity with the KAP8-2 gene in goats and reindeer.

The hair follicle structure is more complex than thought, with new findings on protein formation.

This study suggests that varying intersheet interactions may explain the differences between the two polymorphic forms of macrofibril assembly in Merino wool and hair.
