Biomedical potential of chitosan-silver nanoparticles with special reference to antioxidant, antibacterial, hemolytic and in vivo cutaneous wound healing effects.

The aim of the present study was to prepare chitosan-PVA-silver nanoparticles (CS-AgNPs) through green method. Chitosan and PVA polymers acted as stabilizing agents. DLS and TEM analyses showed that CS-AgNPs were homogeneously dispersed in matrix with an average size of 190-200 nm.

The Potential of a Brown Microalga Cultivated in High Salt Medium for the Production of High-Value Compounds.

sp. was isolated from the Sfax Solar Saltern and cultivated under hypersaline conditions. It contains moderate rates of proteins, lipids, sugars, and minerals and a prominent content of bioactive compounds: polyphenols, chlorophyll a, carotenoids, and fatty acids.

A cysteine protease isolated from the latex of Ficus microcarpa: purification and biochemical characterization.

A plant protease named microcarpain was purified from the latex of Ficus microcarpa by acetonic (20-40 % saturation) precipitation, Sephadex G-75 filtration, and Mono Q-Sefinose FF chromatography. The protease was purified with a yield of 9.25 % and a purification factor of 8.
