Currently approved neuraminidase inhibitors (NAI) for the treatment of influenza A virus infections are prone to induce viral drug resistance development due to the rapid evolutionary dynamics of the neuraminidase (NA) and hemagglutinin (HA) proteins. Both HA and NA proteins are subject to antigenic drift and the epistatic interactions within and between these proteins can lead to genetic diver...

a hundred and five strains of salmonella havana were studied from the patients of pediatric hospital of tehran and tabriz during 1976-86. the sources of the strains in order to their frequency were from-stool, blood, spinal, fluid, wound and urine. from the epidemiological point of view salmonella havana is serotype of most non-typhoid salmonella. all of the strains had drug resistancy and most...
Purpose: Chronic lymphocytic leukemia (CLL), a malignancy of mature B cells, is incurable with chemotherapy. Signals from the microenvironment support leukemic cell survival and proliferation and may confer chemotherapy resistance. ON 01910.Na (Rigosertib), a multikinase phosphoinositide 3-kinase (PI3K) inhibitor, is entering phase III trials for myelodysplastic syndrome. Our aim was to analyze...

acinetobacter lwoffii, an important nosocomial pathogen, is a gram-negative aerobic bacillus that is a component of the normal flora on the skin, oropharynx, and perineum of about 20-25% of healthy individuals. we herein present a case of a 66-year-old man with combined mitral and aortic valve endocarditis associated with multi-drug resistance acinetobacter lowffii bacteremia.
conclusions it was the first report on the blactx-m-15 gene emergence in clinical enterobacter spp. in iran. the current study demonstrated the predominant presence of the gene encoding ctx-m-15 among esbl producing enterobacter spp. commonly with a large plasmid, in the setting. background enterobacter spp. is increasingly recognized as an important nosocomial pathogen and implicated in many e...
to study the resistance to standard dosage of clopidogrel among iranian patients following percutaneous coronary intervention measured by platelet aggregation test.patients undergoing percutaneous coronary intervention in imam hussein medical center, tehran, iran, who were under treatment with aspirin, but had no history of clopidogrel usage, entered the study. patients received standard dosage...
emerging new medications in the treatment of hbv produces hope and promises for curing of hbv. over the past decade, the development of oral nucleoside/nucleotide analogs (nas) with favorable potencies and tolerabilities has led to substantial advances in chronic hepatitis b (chb) therapy. the oral anti-hbv agents currently approved are lamivudine, adefovir dipivoxil , entecavir , telbivudine, ...
background and objective: implementation of standard methods for accurate detection of bacteria, correct antibiotic susceptibility testing and effective treatment of bacterial infections play important roles in development of public health and prevention of drug resistance. this study aimed to detect bacteria using standard methods and compare the results with the results obtained in teaching h...
