the use of bacteriocins, mainly nisin, is one of the most significant preservation technologies in the food industry. nisin encapsulation can improve stability and homogenous distribution in food matrices. in this study, liposomes of four various lipids (lipoid s 100, lipoid s pc-3, lipoid s pc, and lipoid pc (dppc)) were prepared by dehydration-rehydration method, and compared for entrapment e...

background: disulfiram is oral aldehyde dehydrogenase (aldh) inhibitor that has been used in the treatment of alcoholism. recent studies show that this drug has anticancer properties; however, its rapid degradation has limited its clinical application. encapsulation of disulfiram polymeric nanoparticles (nps) may improve its anticancer activities and protect rapid degradation of the drug. mater...

horseradish peroxidase was encapsulated in calcium alginate for the purpose of phenol removal. considering enzyme encapsulation efficiency, retention activity and enzyme leakage of the capsules, the best gelation condition was found to be 1 % w/v of sodium alginate solution and 5.5 % w/v of calcium chloride hexahydrate. upon immobilization, ph profile of enzyme activity changes as it shows high...

Horseradish peroxidase was encapsulated in calcium alginate for the purpose of phenol removal. Upon immobilization, pH profile of enzyme activity changes as it shows higher value at basic and acidic solution. Investigation into time course of phenol removal for both encapsulated and free enzyme showed that encapsulated enzyme had nearly similar efficiency in comparison with the same concentrati...

objective: this study aimed to evaluate a co-encapsulated pegylated nano-liposome system based on two herbal anti-tumor drugs, silibinin and glycyrrhizic acid, for delivery to a hepatocellular carcinoma (hcc) cell line (hepg2). materials and methods: in this experimental study, co-encapsulated nano-liposomes by the thin layer film hydration method with hepes buffer and sonication at 60% amplitu...

We reported two forms (sphere and wire) of newly fabricated chlorhexidine (CHX)-loaded mesoporous silica nanoparticles (MSNs), and investigated their releasing capacities and anti-biofilm efficiencies. The interactions of the blank MSNs with planktonic oral microorganisms were assessed by field emission scanning electron microscopy. The anti-biofilm effects of the two forms of nanoparticle-enca...

AIM The aim of this work was to develop pH-responsive nanoparticles encapsulating CdtB and to demonstrate that these particles represent a potential therapeutic agent for gastric cancer. MATERIALS & METHODS Chitosan/heparin nanoparticle-encapsulated CdtB was prepared and the delivery efficiency was monitored by confocal laser scanning microscopy. The molecular basis of the nanoparticle-encaps...

We consider the use of Jacobian coordinates for Tate pairing over general characteristics. The idea of encapsulated double-andline computation and add-and-line computation has been introduced. We also describe the encapsulated version of iterated doubling. Detailed algorithms are presented in each case and memory requirement has been considered. The inherent parallelism in each of the algorithm...

The main objective of the study was to design a non-condensing polymeric microspherebased gene delivery system for targeting macrophages. An external gelation technique was used to prepare plasmid DNA-encapsulated calcium alginate microspheres. The microspheres were characterized for particle size, surface charge, surface morphology, and DNA loading efficiency. Stability of encapsulated DNA was...
