This research found that variations in the KRTAP gene family are likely responsible for the diverse hair phenotypes seen among mammals, influenced by gene repertoire differences, expression, and evolutionary factors.

This study found a significant shift to the telogen phase in the hair growth of children with classical marasmus compared to normal children, suggesting a connection to the chronicity of the condition.

This study found that the Spanish version of the Hair Specific Skindex 29 (HSS29) is a reliable and valid tool for assessing the quality of life impact of female androgenetic alopecia.

This study validated a Spanish version of the Hair Specific Skindex 29 scale for assessing quality of life in women with female androgenetic alopecia, showing similar psychometric properties to the original.

This study found that Cupiennius salei spiders have specialized mechanosensitive hairs on their legs that adaptively respond to joint movements during walking, suggesting a proprioceptive function.

In this study, hair follicle transcriptomic responses to a 10-day HIIT program revealed both existing and new biomarkers, such as certain miRNAs, offering a potentially effective way to monitor cellular and molecular HIIT adaptations.

This study found that the Spanish version of the hair-specific Skindex-29 questionnaire effectively detected changes in health-related quality of life among women with female-pattern hair loss, and the scores were significantly correlated with the SF-12 survey results after treatment with a 5 alpha-reductase inhibitor.

This study identified a group of dermal fibroblasts near hair follicle stem cells in mice that facilitate hair regeneration by creating a biomechanically compliant extracellular matrix, enhancing stem cell activation and promoting a positive feedback loop for tissue regeneration.

This study found that human scalp hair significantly reduces solar radiation intake, with more tightly curled hair offering greater protection against heat gain compared to a naked scalp.

This study found that Lgr5 and Lgr6 stem cells both activated wound-healing genes, but only Lgr5 stem cells changed their identity to contribute to new skin formation during wound repair.

Researchers translated and validated the WAA-QoL questionnaire into Brazilian Portuguese, finding it to be a reliable tool for assessing quality of life in women with female pattern hair loss.

In this study, the authors successfully translated, culturally adapted, and validated the Women's Androgenetic Alopecia Quality of Life questionnaire into Spanish, demonstrating it as a reliable tool for assessing female pattern hair loss.

This study found that both dark and white dromedary camels exhibited high medullation in hair fibers, suggesting adaptations for insulation and heat dissipation in hot desert environments.

In this study, the researchers reported extensive gene loss and high pseudogenization rates of α-keratin genes in cetaceans compared to terrestrial mammals, likely linked to hair loss and aquatic adaptations.

This study found that the Hr gene loss and positive selection for the FGF5 gene in cetaceans likely contributed to hair loss as these animals adapted to aquatic environments.

This study identified three candidate genes (CORT, FGF5, and CD36) associated with cold climate adaptation in Yanbian cattle through genome resequencing and comparison with African tropical cattle.

This study found that hair follicle gene expression varies between Angus and Brahman cattle and responds to growth-promoting treatments, which may reflect breed differences in adaptability to cold stress.

In this study, researchers propose that the EDAR V370A allele's positive selection in East Asian populations may be linked to stable aquatic resources from Late Pleistocene ecosystems in northern China, suggesting a "nutritional niche construction" framework where these resources offset the allele's metabolic costs.

This study presents a hypothesis that the EDAR V370A allele was positively selected in East Asian populations due to the stable aquatic resources in Late Pleistocene northern China, which may have offset the allele's metabolic costs and provided a selective advantage.

In this study, the researchers used the dual-flow-RootChip to show that Arabidopsis roots can locally adapt their hair development in response to asymmetric phosphate conditions.

This study confirms the presence of large structural variations in the genome of Nellore cattle, which may contribute to their environmental adaptation to tropical regions.

This study found that cetaceans have adapted their fibroblast growth factors to assist in low bone density, hypoxia tolerance, and the development of rigid flippers, reflecting significant evolutionary changes for aquatic life.

Integumentary organs adapt and evolve for survival, with potential uses in regenerative medicine.

The researchers reported that PPARβ/δ may influence the yak hair follicle cycle by modulating lipid metabolism in dermal papilla cells, with varying expression during different hair growth phases, affecting both lipid content and cell proliferation.

This review examines the adaptive value and mechanisms of seasonal coat colour moulting in birds and mammals, highlighting the challenge of camouflage mismatch and the necessity for evolutionary adaptation under climate change.

This study found that ancient and modern Chinese goats share close genetic ties, originating from the Fertile Crescent, with genetic divergence influenced by China's climatic divisions.

This chapter discusses genetic polymorphisms related to phenotypes that differentiate between populations and reports no new results; it highlights the role of DNA technology in understanding human adaptation history.

This study found that the prenatal skin development in Red Sokoto goats undergoes significant morphological changes across gestational stages, which may be important for their adaptation and thermoregulation after birth.

This article explores the origins and differences between human and animal faces, emphasizing the face's role in communication and its relevance to plastic surgery, but presents no new research findings.

The study observed that Friesian heifers experienced significant adaptation challenges to Kenya's equatorial conditions, taking around 18 months for their coat composition to resemble that of Dutch heifers in summer.
