Background and Aim: Yeasts are common contaminants in the cheese industry, which frequently arise from raw milk, surrounding environment, equipment, resulting economic losses addition to health hazards. This study aimed compare antifungal effect of chitosan nano-chitosan as natural preservatives with a commonly used chemical preservative (potassium sorbate) against Rhodotorula mucilaginosa Cand...

Colloidal delivery systems including polymeric selfaggregates have been widely investigated to date, as these formulations may reduce unwanted side effects and may improve the therapeutic effects. Various characteristics of self-aggregates prepared from deoxycholic acid-modified chitosan were investigated by fluorescence spectroscopic and dynamic light scattering methods, and found to be contro...

the effects of chitosan/biopolymer (c/p) and nanohydroxyapatite/ biopolymer (nha/p) weight ratios on particle size and its uniformity, cross-linking density and nh2 content of nano-hydroxyapatite/chitosan/gelatin (nha/c/g) microspheres were investigated. microspheres were fabricated using water-in-oil emulsion. cross-linking of microspheres was performed using water soluble carbodiimide. partic...

• Core-shell carrier systems were developed via layer-by-layer assembly to deliver carvacrol. Particle size and charge of the core–shell carriers greatly influenced by BSA coatings. exhibited better stability under simulated digestion conditions. Chitosan/BSA improved sustained release bioaccessibility The impact encapsulating carvacrol in chitosan-albumin based nano-carriers (NCs) on its was d...

OBJECTIVE In this study, nano-biocomposite composed of poly (lactide-co-glycolide) (PLGA) and chitosan (CS) were electrospun through a single nozzle by dispersing the CS nano-powders in PLGA solution. The cellular behavior of human adipose derived stem cells (h-ADSCs) on random and aligned scaffolds was then evaluated. MATERIALS AND METHODS In this experimental study, the PLGA/CS scaffolds we...

Abstract Root-knot nematodes ( Meloidogyne spp.) have been reported to be responsible for large economic losses of agricultural crops due their wide host range and variety suitable climates. The control measures these parasitic depend upon synthetic nematicides a small number bio-based products. Chemical are eliciting adverse effects on the environment human health. In present study, an alterna...

Biopolymers, such as silk fibroin, collagen, and chitosan, are promising candidates for a variety of applications that merge the fields of biomedical optics and biomaterials. Biocompatible silk fibroin, in particular, shows promise as a biomaterial, based on a number of attributes. Silk fibroin is the strongest and toughest natural fiber known and is easily formed into robust films of thermodyn...

Pancreatic islet transplantation is the only curative, noninvasive treatment for type 1 diabetes mellitus; however, high rates of cell death in the immediate postimplantation period have limited the success of this procedure. Bilirubin, an endogenous antioxidant, can improve the survival of murine pancreatic allografts during hypoxic stress but has poor solubility in aqueous solutions. We hypot...

It is now recognized that adsorption using low-cost adsorbents is an effective and economic method for water decontamination. Chitosan is derived by deacetylation of the naturally occurring biopolymer chitin which is the second most abundant polysaccharide in the world after cellulose. In this study, the capacity of the chitosan nanoparticles was studied for the removal of the anionic Congo red...
