This study observed that high levels of immunoreactive cortisol in the tail hair of captive Asian elephants were often associated with stressful or distinct behavioral events, suggesting its potential for reconstructing their physiological history.

This study found that hair manganese levels did not vary by acute coronary syndrome or stable coronary artery disease severity, but a modest, non-significant correlation with body mass index suggests a potential link between manganese homeostasis and cardiometabolic status that warrants further investigation.

In this study, a significant negative correlation was observed between the 2D:4D digit ratio and maxillary sinus volume in men, suggesting an androgenic hormone influence on sinus volume development.

This review discusses the immune functions of porcine skin and proposes a classification of dendritic cell subsets based on similarities to human skin, but it reports no new clinical results.

This study found that mimicking the XPD point mutation in mice resulted in trichothiodystrophy-like symptoms, supporting the role of basal transcription and DNA repair defects in the disease.

This study found that hair cortisol concentration in free-ranging brown bears is influenced by handling methods, body condition, and potentially both short- and long-term stressors.

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 suggests that epitestosterone may play a role in regulating androgen-dependent processes like prostate growth and body hair distribution by counteracting testosterone's actions.

This review explores the chemical composition and biological activities of essential oils from selected aromatic roots, highlighting their potential for various industries, though more research is needed to standardize their bioactive components.

This review discusses the role of peptidylarginine deiminases in skin homeostasis and diseases, particularly in keratinocyte differentiation and hair disorders, but presents no new experimental findings.

This review discusses using human follicular fluid in metabolomic analysis as a diagnostic tool and predictor of success in assisted reproductive technology for PCOS patients, reporting no new results.

This review discusses the evolution and development of smart and multifunctional microneedles, highlighting their potential future importance in medical applications, but it reports no new experimental results.

This review discusses treatments for demodicosis in adults and children and provides no new clinical results; the authors emphasize the need for careful diagnosis and therapy selection.

This study identified dynamic changes in DNA methylation associated with different growth stages in Tan sheep, which may offer insights to retain their valuable curly fleece as they age.

This study found that in rodent diabetes models, measuring corticosterone levels in new growth hair was more sensitive to hyperglycemia-induced changes than using old hair or serum samples.

In this study, researchers developed an LC-MS/MS method to accurately quantify cortisone and cortisol levels in human scalp hair, finding that concentrations decrease predictably along the hair shaft, which could assist in identifying abnormal glucocorticoid exposure.

This study identified multiple loss of function variants in the HR gene linked to the unique hair coat phenotype in lykoi cats, also known as werewolf cats.

This review discusses the dermatologic needs and care considerations for transgender patients undergoing gender transition, highlighting the unique role dermatologists can play, but it does not report new clinical results.

This study found that P311 triggers transdifferentiation of epidermal stem cells into myofibroblast-like cells via TGFβ1/Smad signaling during wound healing.

This study highlights multiple factors contributing to hair graying, such as oxidative damage, melanocyte changes, and genetic influences, and suggests that repigmentation may be temporarily reversible, offering potential targets for future treatments while urging caution when applying mouse model findings to humans.

This study found that methanol is more effective than isopropanol at removing external cortisol from grizzly bear hair and suggests that the choice of solvent can influence hair cortisol concentration results.

This publication discusses the 2021 ESC Guidelines for the prevention of cardiovascular disease in clinical practice and reports no new results.

In this study, SNPs in genes affecting skin pigmentation were linked to each skin type's unique response to environmental stress, suggesting potential for personalized skin care products.

This study suggests that prenatal exposure to THC may negatively impact ovarian health in rats by altering miRNA expression, potentially leading to reproductive issues such as subfertility or premature reproductive senescence.

This case study describes a patient with Turner syndrome who, despite lacking many classic features, presented with multiple autoimmune diseases, suggesting a link between complex X chromosome rearrangements and increased autoimmune risk.

This article reviews Miriam Arbeit's skill-based model for promoting adolescent sexual development, highlighting its focus on adolescents as active participants in their own sexual growth but noting areas for further expansion.

This review discusses how targeting protein degradation processes may help overcome cancer drug resistance, but reports no new clinical results and suggests further research for precise therapeutic strategies.

This study found that both Japanese male and female hair darkens with age, with significant sex differences in melanin composition and melanosome morphology influencing hair color.

This study found that bacterial community structures on hair and scalp differ significantly, with distinct abundances of Pseudomonas on hair and Staphylococcus on scalp.
