Structural characterization, anti-aging activity and mechanisms investigation in vivo of a polysaccharide from Anthriscus sylvestris.

Anthriscus sylvestris (L.) Hoffm has a long history of use for anti-aging, although the anti-aging properties of its decoction ingredients have been seldom explored. This study marks the first detailed examination of the in vivo anti-aging activity of A.

Lysozyme-Immobilized Polyethersulfone Membranes with Satisfactory Hemocompatibility and High Enzyme Activity for Endotoxin Removal.

Endotoxin adsorption has received extensive attention in the field of blood purification. However, developing highly efficient endotoxin adsorbents with excellent hemocompatibility remains challenging. In this study, we propose a new approach for developing the functional polyethersulfone (PES) membrane to remove endotoxins.

In-situ formation of silver nanoparticles on poly (lactic acid) film by γ-radiation induced grafting of N-vinyl pyrrolidone.

A fast, easy and novel method for preparing biodegradable polymer films with silver nanoparticles was investigated to endow the material with excellent biocompatibility and antibacterial property. Silver nanoparticles (Ag NPs) were immobilized on the surface of polylactic acid (PLA) film by gamma radiation induced grafting of N-vinyl pyrrolidone (NVP). In this method, poly (N-vinyl pyrrolidone) (PVP) was produced and grafted onto the surface of PLA film by gamma radiation polymerization of NVP.
