Low oxygen levels can make hair-growing cells better at growing hair through a process involving reactive oxygen species.

In this study, researchers observed that epidermal damage may increase susceptibility to Bacillus anthracis infection, allowing it access through hair follicles and the denuded dermis in mice.

This study found distinct skin surface changes, including faint mosaic melanoderma and atypical scaliness, on long-standing sun-exposed balding scalps that may be associated with actinic field carcinogenesis.

In this study, researchers observed a high degree of plasticity in somatosensory axons innervating Merkel cells in adult mouse skin, revealing that both epithelial-neural crosstalk and intrinsic neural mechanisms contribute to axonal patterning and remodeling during epithelial homeostasis.

This study observed that root hair growth in Arabidopsis occurs episodically, with each growth period associated with external alkalization and internal acidification, suggesting a role for proton influx in facilitating polar growth.

This review discusses fractionated reirradiation as a potential treatment for recurrent brain tumors in children and highlights ongoing challenges with managing craniospinal dissemination; it provides no new clinical results.

This study in adult mice found that somatosensory axons innervating Merkel cells in the skin are highly plastic, with significant remodeling in response to epithelial turnover, and that Merkel cells play a role in limiting axonal branching and promoting their maturation.

This study found that the occipital scalp had significantly higher epidermal nerve fiber density than the frontoparietal scalp, which may explain increased sensitivity in some patients.

This compilation on contact and occupational dermatology in the Asia-Pacific region discusses various allergens and irritants without reporting new clinical findings.

This article discusses current visualization methods for assessing hair restoration therapy responses, noting imprecision in triangulated measurements and patient dissatisfaction with visible tattoos.

In their 1957 study, Neuman and Neuman suggested that magnesium deficiency may inhibit the ion exchange process required for calcium ions to enter extracellular fluid, potentially affecting calcium mobilization.

This review discusses the relationship between ectodermal alterations and immunodeficiencies, particularly the roles of hyper-IgE syndrome, ectodermal dysplasia, and FOXN1 gene mutations, but it presents no new research findings.

This case report presents a very rare instance of pilonidal sinus in the preauricular region, marking only the second known case documented in medical literature.

LED light helps human hair root cells grow and prevents them from dying by activating specific growth pathways.

This review discusses the cornification process of epidermal keratinocytes in forming the skin barrier and reports no new results; it emphasizes the importance for diagnosis and treatment of skin disorders.

In this laboratory study, researchers observed that mouse vascular endothelial cells exhibit dynamic changes after exposure to ionizing radiation, including a transient endothelial subpopulation that facilitates vascular-epidermal communication and skin repair, with shifting roles in angiogenesis and immune surveillance over time.

This study found that Biofield Energy Healing Treatment significantly increased the proliferation of human hair follicle dermal papilla cells in vitro, suggesting potential as a hair growth enhancer.

This review discusses arsenic trioxide therapy in acute promyelocytic leukemia and introduces a novel method using hair analysis to monitor arsenic exposure and correlate it with treatment timing, but reports no new clinical results.

This case report describes a patient who developed localized hypertrichosis of the pinnae after undergoing orchiectomy and chemotherapy for testicular carcinoma.

This review examines dermatological side effects of taxane chemotherapy reported in past studies and highlights the necessity for identifying and managing these conditions to maintain cancer patients' quality of life; it presents no new clinical results.

This study suggests that elevated copper levels in domestic tapwater, exacerbated by its aggressive properties, likely contribute to green hair by damaging the cuticle and increasing copper uptake.

This study found that epidermal stem cells in nonglabrous skin are connected to the distal end of the arrector pili muscle, which may play a role in epidermal renewal and wound healing.

This study found that porcine ear skin is more suitable than excised human skin for investigating the efficacy of barrier emulsions in preventing pollen allergen penetration due to its lack of tissue contraction.

LED light helps human hair root cells grow and move by activating certain cell pathways.

This study identified a novel microscopic "arrow sign" in hair root sheaths of patients on EGFR inhibitors, potentially aiding in diagnosing related hair changes and differentiating from fungal infections.

In this study involving patients with coronary artery disease, a preauricular crease was present in 77% of cases, suggesting it may be worth investigating for association with the condition.

This case report describes a 40-year-old woman who developed erythema annulare centrifugum, a type of skin rash, likely triggered by taking the drug aceclofenac.
