emergence of resistance among pathogenic bacteria against available antibiotics is posing a great challenge to the current world. thus, there is a great need to discover novel antibiotics. traditional plants have been proved to be novel source in the search of antimicrobial compounds. the current study pertained to the susceptibilities of some clinically significant bacterial species to various...

background: according to the recent studies, the antibacterial activities of silver nanoparticles (ag-nps) were studied on gram-positive staphylococcus aureus and gram-negative escherichia coli. in this study antibacterial effect of silver nanoparticles that used for coating textiles, on e.coli and s.aureus was investigated. methods: silver nanoparticles were coated on textile fabric by corona ...

background and objectives:plant essential oils are sometimes considered for use as antimicrobial agents in foods and medicines and they could be combined with other antimicrobial agents to strengthen the effect and/or reduce the required dose. this study was conducted to determine the chemical composition of the ocimum basilicum, salvia officinalis and trachyspermum ammi essential oils and eval...

a simple, inexpensive and one-step synthesis route of ag-tio2 nanoparticles by arc discharge method isreported. the resulting nanoparticles were characterized using x-ray diffraction and scanning electronmicroscopy. x-ray diffraction patterns demonstrate dominance of rutile to anatase phase in tio2 andformation of silver metal on tio2 after arc discharge process. scanning electron microscopy im...

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 Increasing resistance of pathogenic bacteria to antibiotics is a severe problem in health care and has intensified the search for novel drugs. Cationic antibacterial peptides are the most abundant antibiotics in nature and have been frequently proposed as new anti-infective agents. Here, a group of diastereomeric (containing d- and l-amino acids) peptides is studied regarding their p...

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...

The species Hancornia speciosa (mangabeira) has varied potential. bark astringent properties, latex is used for tuberculosis, ulcers, herpes, dermatoses and warts, leaf tea menstrual cramps the root decoction to treat dislocations hypertension. aim of this work was analyze chemical composition fixed oil antibacterial activities alone or in association with aminoglycosides against standard MDR b...

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...
