It seems well established that CpG oligonucleotide Th1-biased adjuvant activity can be improved when closely associated with a variety of antigens in, for example, microparticles. In this context, we prepared 1-micron near non-charged poly(lactic-co-glycolic) acid (PLGA) 502 and PLGA 756 microparticles that loaded with high-efficiency antigen (50% ovalbumin (OVA), approximately) into their matr...

Aqueous Two-Phase Systems (ATPS) are aqueous droplets dispersed in an phase. This specific behavior arises from interactions between at least two water-soluble entities, such as thermodynamically incompatible polymers. A simple, fast, and “green” process to produce ATPS with core would be of high interest the pharmaceutical field for drug delivery. However, date, rapid destabilization represent...

The absorption of non-steroidal anti-inflammatory drugs (NSAIDs) through the nasal epithelium offers an innovative opportunity in field pain therapy. Thanks to bonding chitosan mucosa and its permeability-enhancing effect, it is excellent choice formulate microspheres for increase drug bioavailability. aim our work includes preparation spray-dried cross-linked non-cross-linked chitosan-based de...

Drug efflux-transporters serve as a major barrier to anticancer drugs at the target site. One strategy to enhance the therapeutic efficacy of drugs against cancer is to increase their available concentrations at the target site by suppressing or modulating efflux-transporters. This manuscript deals with the development and evaluation of the particle type drug delivery system made of stearic aci...

Background: Pseudomonas aeruginosa biofilm is one of the problems in antibiotic treatment of infections. Nanomedicines such as chitosan can carry multiple drugs and improve the therapeutic effects of antibiotics. Objectives: The study aimed to synthesis and characterization of ciprofloxacin loaded chitosan nanoparticle for eradication biofilm of P. aeroginosa. Methods: Cipro-CS microparticles...

the present study involves preparation and evaluation of gastric-mucoadhesive microparticles with metformin hydrochloride as model drug for prolongation of gastric residence time. the microparticles were prepared by the emulsification solvent evaporation technique using polymers of carbomer 934p (c) and ethylcellulose (ec). the microparticles were prepared by emulsion solvent evaporation method...

Commonly used polymer-based scaffolds often lack visco-elastic properties to serve as a replacement for cartilage tissue. This study explores the effect of reinforcement of silk matrix with chitosan microparticles to create a visco-elastic matrix that could support the redifferentiation of expanded chondrocytes. Goat chondrocytes produced collagen type II and glycosaminoglycan (GAG)-enriched ma...
