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 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 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.

Caloric restriction improves skin and fur structure but can cause muscle loss and movement issues.

This study observed that during the postnatal development of gray short-tailed opossums, skin transitions from facilitating gas exchange through a dense capillary network at birth to supporting thermoregulation, with significant changes in skin thickness and structure occurring by 35 days old.

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.

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.

This study identified several candidate genes related to wool production traits and adaptation to hot, arid environments in Iranian sheep, highlighting potential targets for future inbreeding programs.

This study suggests that hair loss was a metabolic adaptation allowing hominids to evolve larger brains by alleviating dietary restrictions on essential amino acids for hair and brain development.

This study found that humans have a significantly slower wound-healing rate compared to non-human primates and other animals, suggesting that slow wound healing is a characteristic unique to humans within the primate order and potentially indicating evolutionary adaptations.

This study observed structural and molecular changes in Ganxi goat skin that adapt to hot and humid climates and suggested that GSDMA might play a role in hair follicle regulation and skin homeostasis, though further research is needed to confirm its function in environmental adaptation.

In this study, researchers identified two significant genetic polymorphisms in the 3'-UTR of the HSP70 gene in Moa buffalo, which may play an important role in heat adaptation, providing insights for conservation and performance improvement in tropical climates.

This study found that a mutation in the BMP12/GDF7 gene is associated with the Naked neck trait in chickens, reducing neck feathering due to altered signaling pathways.

This article reviews the thermoregulation mechanisms in African and Asian elephants and highlights challenges from climate change, with no new empirical results presented.

In this study, Min pigs were found to have unique characteristics for secondary hair growth compared to Berkshire and Yorkshire pigs, with the Wnt and BMP signaling pathways stimulating follicle stem cell activity and promoting secondary hair growth and gene expression.

In this study, researchers identified genetic variants in the PCCA and PRLR genes that are significantly associated with hair coat length in Brangus heifers, potentially contributing to more thermotolerant cattle.

This review discusses current knowledge on the biological mechanisms of different types of alopecia but reports no new clinical findings; the authors highlight future research directions, especially regarding epidermal stem cells and immune pathways.

This review discusses the side effects and diseases related to hairstyles and hair treatments among black women, highlighting the need for thorough examination by dermatologists, but reports no new clinical results.

This study observed that in wild snowshoe hares, gene expression patterns during seasonal coat color change show a consistent lag between gene expression and visible coat color changes.

This article reviews current research on animal models for hair regrowth treatments and reports no new findings; it highlights the need for studies comparing therapy efficiency and long-term safety.

This study found that Pannexin 3 plays a crucial role in skin development by regulating the transcription factor Epiprofin, affecting keratinocyte differentiation and hair follicle regeneration in mice.

This study revealed key cellular dynamics and interactions during early embryonic mouse skin development, highlighting complex transitions from precursor states to diverse multilayered structures.

This review discusses the evaluation of animal models for hair research and regeneration, highlighting their importance and limitations, and calls for improved approaches to advance understanding of human hair diseases.

This study developed a method to measure local steroid hormone concentrations in hair, providing new insights into hormone dynamics associated with androgenetic alopecia.

In this study, researchers used scanning electron microscopy to analyze hair damage from 3% hydrogen peroxide and UVB radiation, observing that Caesalpinia sappan hair tonic formulations coated and interacted with the hair cuticle, potentially modifying hair fiber damage.

This perspective suggests that browning agents may not directly enhance UCP1 expression in white adipose tissue but instead induce browning through increased heat loss, prompting thermogenesis to compensate.

This review discusses the possible impacts of prolactin on skin conditions like psoriasis, alopecia, and stress-related dermatoses, emphasizing the need for further research to explore its therapeutic potential.

This study found that nanostructured lipid carriers with clobetasol propionate significantly enhance follicular drug delivery compared to commercial cream, and manual massage further doubles follicular retention.

This study found that shift nurses exhibited lower circadian variations compared to daytime nurses, indicating an adjustment of their biological clocks to continuous shift schedules.

This review discusses the typical wound healing process in skin and the oral cavity, and emphasizes the research focus on achieving scarless healing in adult skin, but reports no new clinical results.
