This report describes a rare case of tumoral calcinosis presenting as a slow-growing mass on the scalp in an Afro-Caribbean man, with histopathology revealing calcium deposits and associated tissue changes.

This study found that hypoxic preconditioning of nanofat from donor mice reduced its vascularization capacity in vivo, suggesting that this approach cannot currently enhance nanofat's regenerative potential.

This study demonstrates that using transwell culture significantly influences hair follicle formation in skin models, potentially improving dermatology and skin research methodologies.

This study identified that keratotic basal cell carcinomas with citrulline-positive keratin and hair papilla-like structures are highly differentiated, which helps distinguish them from squamous carcinomas.

This study concluded that Polyquaternium-10 conditioner softens the surface of the scale face on hair fibers.

This study found that the 16th-century mummified hair from a female mummy in Paju was remarkably well-preserved, with the hair's ultrastructural features maintained likely due to a calcium-rich surface coat.

In this study, canna was identified as the most effective plant for water purification in eutrophic conditions, supplemented by reed, with significant differences in pollutant absorption among the five plant species tested.

This study found that chemical treatments such as hair bleach and UV radiation significantly reduced the amount of 18-methyleicosanoic acid on the outer surface of human hair.

This study found that white hair demonstrated denser and more hydrophobic properties compared to black hair.

This study observed that calcifying epithelioma of Malherbe is composed of tumor cells that differentiate into both hair cortex and outer root sheath, supporting its hair follicle origin.

Reactive lipids from aging cells change the extracellular matrix, affecting cell function and inflammation.

This study observed that treating human hair with NaOH led to partially removed cuticles, resulting in better fiber cohesion and mechanical properties similar to wool, unlike bleach or formic acid treatments, which weakened the fibers.

This study found that the alkaline degradation process of hair keratin using nucleophilic reagents led to different proportions of reaction products compared to wool, particularly more lanthionine and lysinoalanine residues.

This research observed that during the catagen phase, the inner root sheath of hair follicles becomes an early target, highlighting its potential role in maintaining hair follicle homeostasis.

In this study, liposome-encapsulated thioglycolic acid improved hair perming by enhancing the penetration of perm solutions, resulting in a stronger S-shaped wave and higher cysteine content compared to the control.

This study found that modifying biphasic calcium phosphate/poly(methyl methacrylate) bone cement with human hair keratin improves its hydrophilicity, mechanical properties, and supports bone repair in rats, indicating potential for orthopedic applications.

This study found that encapsulating dermal papilla spheroids in alginate hydrogel with extracellular matrix proteins increased alkaline phosphatase activity, suggesting an enhanced manipulation of dermal papilla activity.

In this study, a new pH-responsive hydrogel composed of polyvinyl alcohol and boric acid was found to release salvianolic acid B effectively, reducing excessive scar formation and enhancing tissue regeneration during early-stage wound healing.

Hair increases in size when it absorbs water, and treatments like bleaching affect how much water it can take in.

This study found that papain/bisulfite disintegrates human hair cuticles by dissolving the endocuticle, potentially accelerated by ethanol's removal of cell membrane material.

This study suggests that using glycosidases to lyse the polysaccharides of Botryoccocus braunii may allow for the semi-continuous recovery of hydrocarbons while keeping the cells viable.

The optimized Cinchonine gel effectively fights acne bacteria and is safe for twice-daily use.

This study found that mouse hair follicle stem cells in a quiescent state exhibit greater chromatin dynamics and de-differentiation potential, suggesting higher cell fate plasticity compared to their proliferative or differentiated counterparts.

This study found that involucrin likely plays a key role in forming the cornified material of the medulla and inner root sheath of human hair, contributing to its mechanical strength.

In this study, researchers observed that quiescent mouse embryonic fibroblasts showed reduced glycolysis but increased TCA cycle flux and mitochondrial respiration, with these changes linked to metabolic reprogramming involving yes-associated protein inhibition and malate cycle modulation, which supports extracellular matrix protein synthesis.

This study indicated that a novel calcium-phosphate nanoflower coating on titanium surfaces had high surface area, low cytotoxicity, and promising cell affinity, suggesting it could be a potential alternative modification method for titanium implants.

This study found that hydrophilic carbon dots (Lys-CA-CDs) induced bovine serum albumin to form more wormlike fibrils, while inhibiting hen egg white lysozyme from forming hair-like fibrils.

This study found that digital perm treatments using sodium thioglycolate lotion led to the most significant reduction in protein content and greater hair damage compared to other methods and lotions.

In this study, the researchers found that tyndallization effectively sterilizes aqueous solutions of hyaluronic acid without diminishing their regenerative properties, and these properties remain intact even at low temperatures, supporting potential applications in cryobiology and cryomedicine.

Lacto-fermentation changes amino acid profiles in bovine colostrum, but results are inconsistent.
