The 15th-century Korean mummy's hair was well-preserved due to a protective lime-soil coating.

This study found that adding 1.5% lactic acid to mink diets during the hair growth period significantly improved production performance and maintained visceral health.

This study found that an injectable calcium alginate-amelogenin hydrogel is biocompatible, degradable, anti-inflammatory, and promotes osteogenesis, which may enhance the bone healing process in jaw and facial bone defect areas by mediating the bone immune microenvironment.

This study concluded that the process of mummification disfigures facial features, making identification challenging, but commercial shrunken heads retain more defining features compared to ceremonial ones.

In this study, researchers developed a GelMA-based gradient pH hydrogel that effectively reduced bacterial load and promoted fibroblast and endothelial cell proliferation, macrophage polarization, neovascularization, and hair follicle regeneration, offering a promising treatment for bacterially infected skin wounds.

This study observed that both TCA (35%) and GA (70%) chemical peels improved skin morphology and stimulated bulge stem cells in albino rats, with no significant difference between the two agents.

This study found that using ionic liquid for specimen preparation allowed for observation of dermal papilla cells and their cilia in near-living conditions, reducing damage typically caused by conventional preparation methods.

Feathers become harder as they develop due to a change in keratin type.

In this study conducted using an in vitro model with rabbits, researchers found that citral from lemongrass oil, especially at a 1% concentration, improved comedone erythema and tissue hyperplasia, suggesting its potential as a treatment for comedone acne.

The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.

This study argues that the reported "toughening" transition in keratin is a misinterpretation, actually representing the evaporation peak of residual water in the fibers.

In this study, researchers observed that Zibai ointment promoted chronic wound healing in rats by influencing the bFGF/Wnt/β-Catenin signaling pathway, demonstrating a higher wound healing rate compared to other treatments.

This study developed a new quantitative method to measure skin cell turnover in just 4 days, showing it can effectively differentiate skincare product performance and revealing that turnover slows with age but responds more to treatments as people get older.

This study hypothesizes that a mummified 19th Century girl in San Francisco died of severe undernourishment potentially due to a bacterial-borne disease, highlighting historical health challenges mitigated by modern sanitation and medicine.

This study explored spontaneous repigmentation after phenol-croton oil peels in skin of color, finding that temporary hypopigmentation resolved by day 21 in both a black-skin domestic pig model and human clinical observations, highlighting potential for these procedures despite past concerns about pigmentation issues.

This study found that keratin filament networks in SG1 cells of mice undergo dynamic changes during cornification, impacting the barrier function of the stratum corneum.

Lower acetylation makes chitin nanofibers thinner and more suitable for various uses.

In this study, cinnamaldehyde loaded onto gypsum-calcium carbonate scaffolds showed promise in promoting early-stage bone healing in rats but was less effective at later stages, with better results when combined with dehydrothermal treatment.

This study evaluated a microemulsion-based flushing fluid made with castor oil that effectively removed 84.85% of mud cake formed by drilling fluid, highlighting its Newtonian fluid behavior and high wettability inversion capability.

Lactic acid bacteria fermentation can turn waste into valuable skincare ingredients.

In this study, researchers developed a method using stencils to create controlled stiffness gradients in alginate hydrogels, revealing that stiffer regions within the gels promote deeper invasion by breast cancer cells, facilitating the study of mechanosensitive cellular behaviors.

This study found that combining optical clearing methods with light-sheet fluorescence microscopy allows detailed 3D visualization of normal and pathological human skin biopsies, revealing differences in epidermal thickness and volume.

This review discusses the evolution and studies of injection lipolysis for fat reduction, highlighting the need for more research to ensure patient safety and treatment efficacy; it reports no new clinical results.

This study describes a double embedding technique for preparing tangential sections of hair and wool fibers, recommending specific staining methods for quantitative analysis and demonstrating wool fiber cortical fractions.

This study found that citric acid treatment can significantly improve the structural integrity and mechanical properties of chemically treated hair, reducing damage by increasing keratin crosslinking density and decreasing crystallized calcium soaps, with varying effectiveness depending on the type of chemical treatment.

This study found that photochemical and cosmetic chemical oxidation of hair causes surface damage by delipidation and acid formation, which can be characterized and quantified using microfluorometry and X-ray photoelectron spectroscopy.

This case report suggests that intracanal medication with calcium hydroxide paste may alleviate colitis symptoms triggered by Formacresol used during dental retreatment in a 46-year-old patient.

This study revealed that hair cells undergo an organized process to become keratin-packed "zombie" cells, highlighting a key area for treatment development in the first 1mm of hair follicles.

This study investigated the electron transfer processes in an iron-mediated DAMO–anammox system, finding that Fe3+ accelerated c-type cytochrome-mediated electron transfer and suggested that riboflavin acts as an electron shuttle and DIET may occur among these microorganisms.
