Large-scale use of antibiotics in food animal farms as growth promoters is considered as one of the driving factors behind increasing incidence of microbial resistance. Several alternatives are under investigation to reduce the amount of total antibiotics used in order to avoid any potential transmission of drug resistant microbes to humans through food chain. Copper sulfate and zinc oxide salt...

The development of nonviral vectors for the efficient and safe delivery to cells has long been awaited to facilitate gene therapy. Recently, many nonviral vectors modified with cationic lipids, cationic polymers, etc. have been reported. However, those nonviral vectors with cationic materials require improved stability, longer duration of gene expression, and reduced cytotoxicity. We successful...

Protein–polysaccharide biopolymer particles composed of potential acrylamide inhibitors, including zein, chitosan, alginate, and pectin, were used for mitigation in this study. The synergistic effect zein polysaccharides complex was hypothesized to inhibit formation at high temperature. A reaction model utilizing a glucose asparagine solution heated 170 °C 30 min heating block implemented. Zein...

Drug delivery is the most essential feature in drug administration facility and the design of Nanosystems makes the action more consistent an appropriate. Polymer nano particles bind efficiently to the drug and disperse the drug proficiently into the system. The efficacy of many drugs is often limited by their potential to reach the site of therapeutic action. In most cases (conventional dosage...

The aim of the present study was to evaluate the transfection potential of chitosan-coated, green-fluorescent magnetic nanoparticles (MNPs) (chi-MNPs) after encapsulation inside polyethylglycol (PEG)ylated liposomes that produced lipid-encapsulated chitosan-coated MNPs (lip-MNPs), and also to evaluate how these particles would distribute in vivo after systemic injection. The transfection potent...

meso-Tetra(N-methyl-4-pyridyl) porphine tetra tosylate (TMP) is a photosensitizer that can be used in photodynamic therapy (PDT) to induce cell death through generation of reactive oxygen species in targeted tumor cells. However, TMP is highly hydrophilic, and therefore, its ability to accumulate intracellularly is limited. In this study, a strategy to improve TMP uptake into cells has been inv...

Alternating current (AC) electrophoretic deposition (EPD) was used to produce multifunctional composite coatings combining bioactive glass (BG) particles and chitosan. BG particles of two different sizes were used, i.e., 2 μm and 20-80 nm in average diameter. The parameter optimization and characterization of the coatings was conducted by visual inspection and by adhesion strength tests. The op...

Glucan particles (GPs) are 2–4 m spherical, hollow, porous shells extracted from Baker’s yeast, Saccharomyces cerevisae. The surface of the GPs is composed primarily of 1,3--glucan and the particles are efficiently phagocytosed via receptor-mediated cell uptake by macrophages, phagocytic cells expressing glucan receptors. The hollow cavity of the GPs allows for efficient absorption and encaps...

It is well accepted that natural tissue regeneration is unlikely to occur if the cells are not supplied with an extracellular matrix (ECM) substitute. With this goal, several different methodologies have been used to produce a variety of 3D scaffolds as artificial ECM substitutes suitable for bone and cartilage tissue engineering. Furthermore, osteochondral tissue engineering presents new chall...

The aim of this study was to compare protein-loaded inhalable microparticles manufactured using a range of biocompatible polymers including hydroxypropyl cellulose (HPC), chitosan, hyaluronic acid, alginate, gelatin, ovalbumin and poly(lactide-co-glycolide) (PLGA). Spray-drying was used to prepare microparticles containing bovine serum albumin labeled with fluorescein isothiocyanate (BSA-FITC)....
