materials and methods in this study, biodegradation of amoxicillin by baf was evaluated in the aquatic environment. in order to assess amoxicillin removal from the aquatic environment, this bioreactor was fed with synthetic wastewater at four amoxicillin concentration levels and three hrts. results the results showed that maximum amoxicillin and chemical oxygen demand (cod) removals by aerated ...
the reaction of 3-chloropropyl boehmite nanoparticles with caffeine and sulfuric acid afforded bnps-3-propyl-imidazolopyridinium hydrogen sulfate [bnps-caff]hso4 as a new bnps-supported ionic liquid (il) catalyst. [bnps-caff]hso4 proved to be an efficient heterogeneous catalyst for the synthesis of pyrazolopyranopyrimidines via a one-pot four-component reaction of hydrazine hydrate, ethyl aceto...
background: innovative bioactive films incorporated with antimicrobial agents have been recently developed for food preservation. the aim of this study was to evaluate antibacterial activity of polylactic acid (pla) films incorporated with ziziphora clinopodioides essential oil (zeo) and ethanolic propolis extract (epe) against some common food-borne pathogens. methods: the volatile chemical co...
background and objective: the aim of the study was to evaluate the clinical effects of a mouthwash containing sage (salvia officinalis) extracts on streptococcus mutans (sm) causing dental plaque in school-aged children. material and methods: a double blind clinical trial study was conducted in a dormitory on 70 girls aged 11-14 years having the same socioeconomic and oral hygiene conditions....
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...
background silver has been used from ancient times by humans, and recently nanoparticles of silver have been used in many aspects of human life including as a potent antibacterial agent. objectives in the current study a completely green method to prepare silver nanoparticles is reported. two types of starches (potato and corn starches) were used to produce and stabilize silver nanoparticles. a...
conclusions due to the variable nature of antibiotic susceptibility patterns and etiological agents of septicemia, continual assessment of the most frequent pathogens associated with bloodstream infections and detection of their sensitivity patterns to locally available antibiotics seem to be reasonable measures. results from a total of 491 blood cultures, 74 (15.1%) samples were detected as po...
