Chitosan plays an important role in regulating growth and eliciting defense in many plant species. However, the exact metabolic response of plants to chitosan is still not clear. The present study performed an integrative analysis of metabolite profiles in chitosan-treated wheat seedlings and further investigated the response of enzyme activities and transcript expression related to the primary...

Phthalates are known as endocrine disruptors and common in plastic polymers, varnishes, printing inks. However, they most often enter the human body through food. Plastic materials that hold food contain different chemicals, phthalates one of them. can also be found microplastics since microplastic particles serve a vector for chemicals slowly released into beverages. The aim this preliminary s...

Industrial rare earth element (REE) separations predominantly utilize solvent extraction processes tailored toward conventional resources such as bastnäsite, monazite, and ion adsorption clays. Advances in diglycolamide (DGA) chemistry have shown effective characteristics for REE separations. However, limitations associated with traditional DGA techniques, third-phase formation gelling, hindere...

Abstract Background The distribution of drugs could not be controlled in the conventional delivery systems. This has led to developing a specific nanoparticle-based system, called smart drug In cancer therapy, innovative biocompatible nanocarriers have received much attention for various ranges anti-cancer drugs. this work, effect an interesting and novel copolymer named "dimethyl acrylamide-tr...

OBJECTIVE The study objectives were to (1) assess the efficacy of N,O-carboxymethyl chitosan on postsurgical adhesion formation after cardiac surgery using a rabbit cardiac injury model and (2) explore the mechanism of action of N,O-carboxymethyl chitosan in the prevention of postsurgical adhesions using in vitro experimentation. METHODS In the rabbit cardiac injury model, cardiac injury was ...

A technique for producing micrometer-scale structures over large, nonplanar chitosan surfaces is described. The technique makes use of the rheological characteristics (deformability) of the chitosan to create freestanding, three-dimensional scaffolds with controlled shapes, incorporating defined microtopography. The results of an investigation into the technical limits of molding different comb...
