Summary: Biopolymeric injectable hydrogels have been developed for myocardial regeneration applications, but they usually lack desired functionalities. In this study, gold nanoparticles (AuNPs) were synthesized using lysozyme nanofibrils (LNFs) as nanotemplates and incorporated into gelatin-hyaluronic acid (HA) hydrogels. The resulting nanocomposite hydrogels showed improved properties such as rheological properties, mechanical resilience, antioxidant activity, and electrical conductivity. The presence of AuNPs also allowed the hydrogels to be monitorable through computer tomography. This work demonstrates the excellent potential of LNFs and AuNPs@LNFs for formulating functional injectable biopolymeric nanocomposite hydrogels for myocardial regeneration applications.

Summary: Several five-membered bromolactones were synthesized from D-xylonolactone and D-ribonolactone, which are related to the C1-C5 portion of mycalin A lactone. The bromination of D-ribonolactone with HBr/AcOH, without transesterification, resulted in the majority of the acetylated lactones investigated. The evaluation of their anti-tumor activity indicated that the acetates possess cytotoxicity towards multiple cancer cells, with selectivity towards tumor cells and limited toxicity on healthy cells.

Summary: Polyacrylic acid (PAA) and its derivatives are commonly used as matrices in wound dressings, but their weak wet adhesion limits their clinical application. In this study, a PAA-based coacervate hydrogel with strong wet adhesion capability is created by mixing PAA copolymers with isoprenyl oxy poly(ethylene glycol) ether and tannic acid. The coacervate exhibits solid adhesion to both dry and wet substrates, with an adhesive strength to skin of 23.4 kPa and 70% adhesion underwater. It also possesses desirable self-healing and extensible properties, making it suitable for joints that undergo frequent movement. The coacervate demonstrates antibacterial activity, facilitates fibroblast migration, modulates macrophage polarization, shortens hemostatic time, and promotes collagen deposition, angiogenesis, and epithelialization, suggesting its promising potential as a wound dressing in medical translation.

Summary: Nanovesicles have been widely studied and used in biomedical applications, but premature leakage of water-soluble drugs hinders their clinical use. Developing effective strategies to prevent leakage is crucial. In this study, we utilized coarse-grained molecular simulations to explore strategies for leakage inhibition. We investigated the effects of cholesteryl hemisuccinate doping and gold nanoparticles on the morphology and structure of nanovesicles. Our findings suggest that cholesteryl hemisuccinate can improve hole defects in the hydrophobic layer, adjusting drug diffusion. Additionally, we studied the effects of particle size, concentration, and surface chemical properties of gold nanoparticles on drug leakage. Physical cross-linking of gold nanoparticles led to increased drug leakage, but surface modification improved dispersion and reduced side effects.
