background:the utility and efficacy of novel materials in tissue regeneration and antimicrobial therapy are contingent upon the employment of either blood derivatives rich in platelets or platelet-poor-plasma (ppp). this effect is largely mediated by the increased or decreased concentration of platelets in the plasma. the current study aimed to analyze and evaluate the impact of platelet-rich (...

in this study, the antibacterial effect of essential oil of tarragon (artemisia dracunculus) on staphylococcus aureus and escherichia coli was evaluated in culture media and iranian white cheese.the tarragon essential oil (eo) obtained by the steam distillation method and its antibacterial activity was evaluated in 96-well microtiter plates containing brain heart infusion broth. the enumeration...

In the present research work three Pakistani medicinal plants were scrutinized for their antibacterial and phytotoxic potentials. The antibacterial and phytotoxic effects were determined for the crude methanolic extract and its subsequent solvent fractions. In case of antibacterial effect the chloroform and ethyl acetate fractions of all tested plants showed moderate antibacterial potential. Al...

the aim of this study is to investigate antibacterial effects of immunodominant proteins isolated from the venom of naja naja oxiana snake against staphylococcus aureus, escherichia coli, bacillus subtilis and pseudomonas aeruginosa.the innate immune system is an important line of defense against bacterial diseases. antibacterial proteins produced by snake venoms have recently attracted signifi...

objective: dental caries is a common infectious disease. streptococcus mutans is the prevalent decay microorganism. the anti streptococcus mutans activity of non fermented and semi-fermented tea has been shown. the aim of this study was to determine the anti streptococcus mutans activity of iranian green and black tea (non fermented and fermented type). materials and methods: the study was expe...

background: recently the role of platelets in the tissue regeneration, wound healing and prevention and control of infections has been reported. we aimed to assess the antimicrobial effect of human platelet concentrate against six bacteria, commonly found in wound and hospital-acquired infections. methods: in vitro susceptibility to samples of 10 random human platelet concentrates was determine...

objective(s): a large ratio of surface to volume of nanoparticles in comparison with bulk ones, will increase the cell penetration and therefore their toxicity. materials and methods: chemical precipitation method was used in order to synthesis of zns:ag quantum dots. their physical properties and characteristics were assessed by x-ray diffraction, ultra violet-visible spectrophotometer, transm...

eight medicinal plants were assessed for antimicrobial activity against lactococcus garvieae isolate obtained from diseased oncorhynchus mykiss collected from rainbow trout fish farms in iran. lactococcus garvieae is among the major pathogens of a large number of fish species cultured in fresh and marine recirculating and net pen production systems. the antibacterial activity of the medicinal p...

chemical precipitation method was used in order to synthesize cdse:ag quantum dots (2-3 nm). their physical properties and characteristics were assessed by x-ray diffraction, ultra violet-visible spectrophotometer and tem (transmission electron microscope) and it was shown that the obtained cdse:ag quantum dots are cubic with high-quality. antibacterial effects of cdse:ag nanoparticles against ...

background and aims: herbal medicines are the major remedy in traditional medical systems and have a great contribution in maintaining human health and preventing many infectious diseases. the aim of this study was to assay antibacterial potential of marrubium vulgare l. extract against klebsiella pneumoniae resistant strains to current antibiotics and also gc/ms analysis to better understandin...
