This study highlights the importance of understanding the rheological properties of hyaluronic acid fillers, including viscosity, cross-linking, and concentration, to optimize their use in addressing facial aging by maximizing clinical effects.

This study found that glycylglycine treatment improved hair softness by enhancing hair alignment and altering internal fiber properties among Japanese women with typically coarse hair.

This study explored the molecular biology of skin adaptations in pangolins, revealing that certain genes for lipid synthesis have inactive patterns, while others related to skin function remain intact, suggesting complex evolutionary changes in their skin physiology.

In this study, researchers identified distinct chromatin regions and regulatory elements that drive keratinocyte-specific gene expression, highlighting complex enhancer modules influencing skin epithelium through a combination of transcriptional activators and repressors.

This study investigated pangolin skin genetics, finding that while sweat gland-related genes are not inactivated, several genes related to sebaceous gland function are, which highlights complex evolutionary adaptations in mammalian skin.

This study demonstrated that in live rodents, actin filaments adjust their structure to facilitate membrane transfer between cellular compartments with different biophysical properties.

This study characterized hair from a patient with a ribosomopathy and identified distinct differences, including reduced hair thickness and lipid content, compared to family members.

This study created a detailed atlas of endogenous peptides across 13 maize tissues during various developmental phases, revealing a complex regulatory network where peptide abundance doesn't always align with their source proteins, signaling unique roles in maize development.

This research investigated aqueous alginate-based hydrogels for delivering minoxidil and reported that using hydroxypropyl-β-cyclodextrin (HP-β-CD) with molar substitution 0.65 significantly enhanced minoxidil's solubility and skin permeability without damaging the epidermis, suggesting potential as an alternative to commercial minoxidil solutions.

This study found that male and female chicken feather morphology and color patterns can be extrinsically modified through molting and resetting the stem cell niche during regeneration.

This study evaluated new aqueous gel formulations of minoxidil without irritants and found that the calcium alginate gel showed the best performance in terms of drug release and skin permeation.

This study found that bleached hair showed optimal protein structural integrity and tensile strength at pH 5, with significant changes in cross-linking, water content, and diameter at more alkaline or acidic levels.

This study observed that the biophysical properties of hair in Caucasian females with brown hair significantly change with age, and smoking or being overweight was linked to smaller hair cross-sectional areas.

This study found that adapalene-loaded solid lipid microparticles may enhance targeted drug delivery into sebum due to their similarity to sebum components, although both this formulation and a standard cream showed equivalent follicular penetration.

This study characterized the stress-strain properties of the human scalp and found that its stiffness increases significantly with load, providing valuable insights for planning scalp surgery procedures.

This study demonstrated that molecular dynamics simulations of keratin could effectively model the mechanical properties of hair, aligning well with experimental data, especially when conducted in vacuum conditions.

This study compiled an archive of 684 genes associated with monogenic hair disorders, identifying previously unrecognized components of Hippo signaling and proposing a new biologically-grounded disease taxonomy.

This study found that a peptide treatment using Protein disulphide isomerase improved the mechanical and thermal properties of over-bleached hair by promoting deeper peptide penetration and attachment.

This study found that the cuticle layer of hair contributes approximately 60% to bending stress, highlighting its significant role in the mechanical properties of hair stiffness.

This study found that while yak belly hair is chemically similar to human hair, its higher porosity and lower mechanical strength limit its usefulness as a substitute in hair dye development.

In this study, researchers linked hair composition and mechanical properties to perceived hair quality, suggesting that hair quality may be genetically determined.

In this study, AMACO was found to be non-essential for the formation or function of anchoring cords in mice, despite its presence in the structure.
