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...

patients and methods sixty children aged between 2 and 12 years, and scheduled for on-pump surgery due to a congenital heart disease were randomly assigned into two groups. oral midazolam (0.5 mg/kg up to 15 mg per patient) and dexmedetomidine (2 µg/kg) were administered 45 minutes pre-anesthesia. children’s anxiety, mask acceptance behavior, hemodynamic measures, and cardiopulmonary outcomes w...

background: to investigate the prevalence of antibiotic usage in children aged <5 years with acute respiratory tract illness (arti) in iran. materials and methods: data were collected from a national health survey conducted in 2010 (iran’s multiple indicator demographic and health survey). participants of this cross-sectional study were selected by multistage stratifi ed cluster-random sampling...

background: listeria monocytogenes is an important gram-positive disease-causing bacterium existing in milk and dairy products. inhibitory effects of mentha pulegium essential oil at concentrations of 0.03, 0.015, and 0.0075% on growth of l. monocytogenes were studied in iranian white cheese during 60 days of storage. methods: essential oil of m. pulegium plant, collected from north of iran, wa...

A novel anti-influenza virus compound, flutimide, was identified in extracts of a recently identified fungal species, Delitschia confertaspora (F. Pelaez, J.D. Polishook, M. Valldosera, and J.Guarro, Mycotaxon 50:115-122, 1994). The compound, a substituted 2,6-diketopiperazine, selectively inhibited the cap-dependent transcriptase of influenza A and B viruses and had no effect on the activities...

Purpose. To provide an overview of the 2009 H1N1 influenza pandemic and antiviral treatment options for influenza. Summary. Influenza infection causes significant morbidity and mortality every year. The high mutation rate and segmented nature of influenza virus genome gives rise to high genetic variability which enables the virus to escape antiviral and vaccine interventions. A novel H1N1 strai...

Influenza virus is estimated to cause 3-5 million severe complications and about 250-500 thousand deaths per year. Different kinds of anti-influenza virus drugs have been developed. However, the emergence of drug resistant strains has presented a big challenge for efficient antiviral therapy. Indole derivatives have been shown to exhibit both antiviral and anti-inflammatory activities. In this ...
