This article reviews the role of polyamines in hair follicle growth and discusses potential therapeutic applications but provides no new clinical results.

This study found that a novel rare variant in ITGB6 may cause intellectual disability, alopecia, and dentogingival anomalies in a specific Pakistani family, highlighting a potential role for ITGB6 beyond enamel formation.

This study found that disrupting the PRL gene in mice alters the timing of hair cycling events, causing earlier molts and changes in hair characteristics, particularly affecting female mice more significantly.

This study found that flumethasone administration in Merino wethers led to variations in wool shedding and initial reductions in wool growth, with full recovery generally observed within 60 days post-treatment.

In this study, the aqueous extract from Phthirusa pyrifolia leaves significantly decreased testosterone levels in male Wistar rats without causing liver or kidney damage, suggesting potential effects on libido and reproduction.

In this study, thyroid disorders were found to significantly affect physical and emotional well-being, with notable prevalence in married, urban, and non-working participants in South India.

This study used genomic analysis to reveal moderate genetic diversity, minimal inbreeding, and specific genes under positive selection in Xiangdong black goats, highlighting their unique adaptation traits and potential for breeding and conservation.

This study found that CD26+ fibroblasts are crucial for effective extracellular matrix production and achieving rapid epidermal and dermal homeostasis in human tissue-engineered skin substitutes transplanted onto rodents.

This study found that, in mouse tail epidermis, stem cells rapidly activate and regenerate new progenitors to repair wounds, with mechanisms affecting their proliferation, differentiation, and migration.

This study found that in Merino-Southdown cross sheep, the presence of the C variant of the KRTAP26-1 gene was associated with higher wool quality, including increased wool yield and staple length.

This study found that zebrafish and sticklebacks, despite differences in their tooth regeneration structures, share a similar genetic program during tooth regeneration, suggesting a conserved "successional dental epithelium" in vertebrates.

In this study, R-CSLM showed promise in evaluating hair shaft diseases by providing high-quality images of hair structures, although further development is necessary for follicle and perifollicular area analysis.

This study describes the structural composition of the skin's dermis in experimental animals, highlighting the arrangement of collagen, elastic, and reticular fibers as well as associated glands and muscles.

In this study, it was observed that NIPAL4 mutations linked to autosomal recessive congenital ichthyosis lead to abnormal skin barrier function due to cytotoxic effects disrupting lipid structure and organization, which topical treatments only partially ameliorated.

This study found that the structure and mineral content of dromedary camel hair, specifically the medulla patterns, medulla index, and elemental composition, change with age, revealing differences among camels aged 1 year, 3-5 years, and 8-10 years.

Among Merino × Southdown cross sheep, this study found that certain variants of the KRT81 gene were associated with differences in fleece weight, but not with staple length or fibre diameter traits.

In this study, researchers discussed how specific protein interactions in reptile skin allow for the development of protective structures like scales and scutes, which facilitated reptiles' adaptation to terrestrial environments.

This review discusses the structural properties, pharmacological effects, and clinical applications of neurotoxins on synapses, reporting no new experimental results.

Keratin-associated proteins are crucial for hair strength and structure.

This review covers the structure, development, cycle, and molecular regulation of hair follicles but does not report new results, aiming to offer insights for addressing hair follicle-related diseases.

This study identified a new gene in sheep, KRTAP36-2, discovering variants associated with wool yield. Variations in this gene were linked to the efficiency of fleece conversion from greasy to clean, which may enhance wool production.

This study identified a unique concentric double-layered structure in both Japanese and Caucasian SHINAYAKA hair, associated with improved flexibility and elasticity, and developed a succinic acid treatment to enhance these properties.

This study identified a new ovine KRTAP21-1 gene variant in sheep, with wool yield affected by the variant, suggesting its potential as a genetic marker for improving wool production.

This study found that STAT3 directly inhibited the activity of the sheep FST gene promoter, consequently reducing cell proliferation and promoting a better understanding of hair follicle development mechanisms.

This review suggests that telocytes in male reproductive organs help organize tissue structure and paracrine factors, impacting organ development and pathology, but more research is needed on their molecular pathways.

This study reported that a new coating made with delaminated Ti₃C₂ MXene nano-sheets and a tea-derived compound effectively protects hair keratin from damage by providing UV screening, thermal dissipation, and antioxidation, while also enhancing mechanical strength and restoring wettability.

In this study, the identification of a novel KAP gene in sheep, named KRTAP36-1, was associated with increased prickle factor in wool, suggesting its potential as a genetic marker for breeding purposes.

This study demonstrates the potential of infrared spectral imaging to assess hair follicle structures and heparan sulfate proteoglycan distribution across different phases of the hair growth cycle, offering promise for alopecia research.

This study examined the age-related changes in the dermal structure of goat skin, providing baseline data on its histomorphology, histochemistry, and histoenzymology.

This genetic study identified four new keratin-associated protein genes in sheep, revealing significant sequence variation and suggesting complex evolutionary dynamics, with unique variants in some sheep breeds linking them to Romanov sheep ancestry.
