this study was performed to investigate the effect of ag+ as an elicitor on the activity of antioxidant enzymes, content of h2o2, accumulation of total tocopherol and antioxidant activity in hairy root cultures of silybum marianum (l.) gaertn. the hairy roots were treated with 2 mm ag+. the treated and non-treated hairy roots were harvested in the same time and data on h2o2 content, dpph, tocop...

objective: development of resistance against many of the commonly used antibiotics is an impetus for further efforts to search for new antimicrobial agents. the aim of the study was determined as antibacterial activity of silver nanoparticles produced by plantago ovata seed extract against pseudomonas aeruginosa. methods: all 30 strains of p. aeruginosa wereisolated from isolates of the urinary...

in this study, silver nanoparticles were synthesized by chemical reduction method at different concentrations of ag colloid in the range of 500-16000 ppm. nanoparticles were deposited by spin coating method on pre-etched glass and si substrates. structural, optical and electrical properties of the samples were studied using scanning electron microscopy equipped with edax, uv-vis spectrophotomet...

Background. There are several diagnostic methods for Helicobacter pylori (H. pylori) infection. A cost-effective analysis is needed to decide on the optimal diagnostic method. The aim of this study was to determine a cost-effective diagnostic method in patients with atrophic gastritis (AG). Methods. A decision-analysis model including seven diagnostic methods was constructed for patients with A...
