background: the application of natural compounds including green tea extract (gte) in food and pharmaceutical industries is limited. encapsulation in nanoliposomes could be used as a delivery system to protect these compounds during processing and storage. objective: in this study encapsulation of green tea extract in nanoliposomes and evaluation of its antibacterial, antioxidant and prebiotic ...

non-steroidal anti-inflammatory drugs (nsaids) have shown antibacterial activity in some recent studies. the aim of this study was to evaluate the antibacterial effect of diclofenac against enterococcus faecalis (e. faecalis) as a resistant endodontic bacterium in comparison with ibuprofen, calcium hydroxide and amoxicillin.the antibacterial activity of materials was evaluated using agar diffus...

objectives the aim of this study was to evaluate the stability of antibacterial properties of nanosilver solution during a period of 9 months against streptococcus mutans, staphylococcus aureus and pseudomonas aeruginosa. materials and methods in this in vitro study, the antibacterial effect of serial concentrations of nanosilver solution and amoxicillin antibiotic as control group on the stand...

nano structured materials have wide range of applications due to their interesting size-dependent chemical and physical properties compared to particles of size in the range of micrometer. copper oxide nano materials are of interest on account of their potential uses in many technological fields. in this study  cuo nanoparticles were synthesized via simple sol gel method using basic cuso4 as we...

in this study, zinc oxide nanoparticles (znonps) were synthesized by chemical method and their antibacterial efficiency against a clinical isolate of staphylococcus aureus was studied. the zinc oxide nanoparticles have shown a commendable inhibition effect on the growth of most notorious bacterial pathogen s.aureus. the nanoparticles size and shapes were characterized by transmission electron m...

radiation degradation of chitosan is one of the most important methods to prepare antibacterial oligochitosans. in this study, the effect of solvent on the reduction of degradation dose and enhancement of the antibacterialactivity of chitosan against pectobacterium carotovorum (pc) has been considered.gamma radiation degradation was applied to chitosan as solid and aqueous solution at dose rang...

antimicrobial activity of the polar and nonpolar extracts of the roots and aerial parts of peucedanum ruthenicum m. bieb., johreniopsis seseloides (c. a. mey.) pimenov and cervaria cervariifolia (c. a. mey.) pimenov were examined against gram-positive and gram-negative bacteria. the polar extracts of the roots and aerial parts displayed no activity against bacteria, while the nonoplar extracts ...

the essential oil of prangos ferulacea (apiaceae) fruits was obtained by hydrodistillation and analyzed by gas chromatography (gc) and gc-mass spectrometery (ms). among the 39 identified constituents accounting for 99.99% of the total oil, the major components were chrysanthenyl acetate (26.53%), limonene (19.59%), alpha pinene (19.50%), delta-3-carene (6.56%), mesitaldehyde (6.09), and germacr...

it is possible to develop new biodegradable active packaging by coating biopolymers on paper-based packaging material and also incorporating proper antimicrobial agents into coating structure. in this study bacterial contamination of two commercial cardboard were evaluated.in order to manufacture an appropriate antibacterial packaging material, coating of chitosan-poly vinyl alcohol blends with...
