This study found that protective measures against COVID-19, such as prolonged mask-wearing and frequent hand washing, were associated with skin issues, hair loss, and nail brittleness among participants in Iraq.

This article discusses the uses and techniques of trichoscopy for hair and scalp disorders and reports no new clinical results.

In this study, researchers developed hollow mesoporous organosilica nanoparticles and confirmed their synthesis using IR spectroscopy, then evaluated the nanoparticles for endocytosis and biocompatibility, although specific results of these tests are not reported in the abstract.

This review discusses the applications of low level laser therapy (LLLT) in wound healing, pain reduction, and treating various conditions, but reports no new clinical results; the authors highlight the need for randomized controlled trials for serious diseases.

This article discusses the rationale, design, and significant findings of the long-running Rotterdam Study but reports no new clinical results.

This article reviews the design and objectives of the Rotterdam Study, as well as summarizes major findings, without reporting new results.

This article outlines the rationale and design of the Rotterdam Study, summarizes its major findings, and updates its objectives and methods; it reports no new research results.

This study found that ZnO nanoparticles in topical skin products do not penetrate beyond the outer skin layers in humans, suggesting minimal safety concerns for subdermal absorption.

This article outlines the rationale, design, major findings, and updated objectives of the ongoing Rotterdam Study, without presenting new research data.

In this study, researchers developed a microfluidics-based method for creating uniform, size-controlled stem cell spheroids that enhance osteogenic differentiation when encapsulated in alginate-RGD microgels.

The researchers described a chip-based bioreactor platform for dynamic perfusion, which may enhance in vitro skin models by introducing mechanical shear stress and extending culture periods.

In this study of patients with Androgenic Alopecia, micro-grafts containing HD-AFSCs resulted in significantly improved hair density and follicle count over 11 months compared to a saline solution, suggesting a potential alternative therapy for hair regrowth.

This study suggests that Notch1 acts as a key signal in skin epithelium, promoting immune cell recruitment and aiding in normal skin repair after damage.

This review evaluates existing research on Keratin 15 to assess its validity as a marker for epidermal stem cells, reporting no new results.

This review highlights the increasing clinical applications of high-frequency ultrasonography in dermatology, particularly for assessing the depth of skin tumors and monitoring inflammatory skin diseases, but reports no new clinical results.

This review outlines the development, applications, and challenges of microneedle-based drug delivery from 2000-2019, particularly highlighting fabrication techniques, but reports no new clinical results.

This study established a new in vitro culture system that supports the growth and dynamic self-organization of hair follicle stem cells and their progeny, promoting a stable population equilibrium.

This study found that IMT-P8, a novel cell-penetrating peptide, effectively facilitated the dermal delivery of proteins and peptides in mouse skin and cell lines, suggesting potential for topical applications in cosmetics and skin diseases.

This study found that inhibiting PKC-β activity with bisindolylmaleimide reduces pigmentation in the skin and hair of guinea pigs and mice by preventing tyrosinase activation.

This study observed that in aged mouse skin, there was an increase in IL-17-expressing T helper cells, γδ T cells, and innate lymphoid cells, and blocking IL-17 signaling reduced skin inflammation and delayed age-related changes, suggesting it as a potential target to mitigate skin aging.

This study highlights that the mammalian target of rapamycin complex 2 (mTORC2)-Akt signaling axis is essential for hair follicle stem cells to return to their niche and regenerate effectively by regulating metabolic pathways.

This study analyzed skin from 538 knockout mouse mutants and identified 50 with epidermal phenotypes, providing valuable insights into genetic conditions and systemic effects related to skin abnormalities.

This study visualized mitochondrial metabolism in cultured bovine hair follicles and plucked human hairs, finding that ROS and mitochondrial polarization correlate in specific hair follicle regions, particularly near keratin deposition sites.

This study reported that exposure to 1,763 MHz radiofrequency radiation stimulated hair growth in vitro by inducing insulin-like growth factor-1 expression in cultured human dermal papilla cells.

In this study, epidermal Notch activation increased jagged 1 expression, leading to skin changes like thickening and blistering, with these effects inhibited when jagged 1 was absent.

This review classifies engineered nanomaterials by composition and application in biomedicine, highlighting diverse uses like regenerative medicine and potential occupational side effects, but reports no new clinical results.

This study reports that the completeness of DNA degradation in hair during cornification varies among individuals and affects the success rates of forensic hair DNA analysis.

This animal study found that dermal papilla cells in hair follicles of chimeric mice can originate from various fibroblasts in the skin, challenging assumptions about their specific lineage.

In this animal study, ultrasound combined with a new microbubble formulation of minoxidil increased hair growth rates and improved follicle characteristics more effectively than minoxidil alone.

In this study, researchers identified three molecules in hair that varied with age, suggesting potential markers for aging and targets for cosmetic products.
