This review discusses the complexities of diagnosing and treating iron deficiency related to nutritional anemia and hair loss, concluding that routine screening and supplementation for hair loss are not yet supported by sufficient evidence.

This article discusses the development of an evidence-based guideline for treating androgenetic alopecia and reports no new research results.

This study demonstrated that enhancing human skin constructs with hair follicles through engineered cell organization and vascularization improved hair growth in immunodeficient mice, suggesting potential advances for treating alopecia and chronic wounds.

This study found that Wnt signalling activates hair follicle fate in hair follicle stem cells by relieving TCF3/4–TLE-mediated repression, with β-catenin being crucial for this process.

Mammalian organs regenerate using stem cells and cell plasticity, but this ability declines with age.

This study suggests that ethylene and lignoceric acid (C24:0) may promote cotton fiber and Arabidopsis root hair growth by activating the pectin biosynthesis network.

This review discusses the various dermatological applications of zinc, including its use in treating infections, inflammatory dermatoses, pigmentary disorders, and neoplasias, and reports no new clinical findings.

This review outlines the various processes activated by the peptide GHK-Cu in tissue remodeling and reports improvements in skin and wound healing but notes a need for further study to fully understand these mechanisms.

This review discusses the pharmacology and toxicology of cyclooxygenase in skin, highlighting its role in inflammation, wound healing, and tumorigenesis, without presenting new clinical results.

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

This review discusses the historical and modern use of silver for reducing infections and aiding healing in burns, wounds, and medical devices, noting its benefits and limitations in various applications.

This study found that hair follicle patterning in development may arise from a combination of epidermal prepattern signals and mesenchymal self-organisation, with fibroblast growth factor and bone morphogenetic protein activities playing key roles.

This review discusses how increased gene copy number for telomerase components may contribute to telomerase up-regulation in cancer cells, although the exact mechanisms are not fully understood.

This study reports that mutations in the SUR2 gene are linked to Cantu syndrome, highlighting the role of KATP channels in cardiovascular health and potential new therapies.

In this study, insulin resistance in polycystic ovary syndrome was highly correlated with unbound testosterone and sex hormone-binding globulin, rather than luteinizing hormone or peripheral androgen metabolism.

This review discusses the potential role of vitamins and minerals in managing non-scarring alopecia but reports no clinical results; the authors advocate for further controlled trials to explore these relationships.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

In this study, human dermal fibroblasts were identified as natural host cells that support productive Merkel cell polyomavirus infection, and the MEK antagonist trametinib was introduced as an effective inhibitor to control the virus.

This study found that macrophages play a crucial role in nerve regeneration by regulating Schwann cell dynamics and remyelination, with Gas6 identified as a key factor in this process.

This article reviews the recognition and management of Staphylococcus aureus toxin-mediated diseases, but it does not present new research findings.

This review discusses the role of the circadian clock in skin functions such as cell proliferation and UV protection and reports no new results; the authors note its potential in studying immune regulation and seasonal behaviors.

This review discusses sex-based differences in immune responses, focusing on genetic, hormonal, and microbiome factors influencing infections like COVID-19, and reports no clinical results.

This review discusses recent strategies targeting the neuroactive steroid biosynthetic pathway to enhance neurosteroidogenesis, highlighting their potential benefits for neurodegenerative and neuropsychiatric diseases, but reports no new clinical findings.

This article suggests that modern lifestyle changes, including diet, stress, and chronic anti-inflammatory medication use, may disrupt the natural process of inflammation resolution, increasing vulnerability to chronic disease.

The AUTS2 gene is linked to neurological disorders and may affect human brain development and cognition.

This review discusses various treatment options for adult female acne, highlighting the need for tailored approaches due to individual patient needs and reports no clinical outcomes.
