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...

All-trans retinoic acid (ATRA) induces complete remission in almost all patients with acute promyelocytic leukemia (APL) via its ability to induce the in vivo differentiation of APL blasts. However, prolonged ATRA treatment can result in drug resistance. In previous studies, we generated a multi-drug-resistant HL60/ATRA cell line and found it to contain a new drug resistance-related gene segmen...

Background: One of the fundamental issues of infectious disease treatment is drug resistance. The aim of the present study was to investigate the first-line anti-tuberculosis drug resistance rates and determine the risk factors related to multidrug resistant mycobacterium tuberculosis.Methods: From March 2011 to September 2012, mycobacterial strains were collected from one hundred fifteen diagn...

The purpose of the present study was to develop the Solutol HS15-based doxorubicin submicron emulsion with good stability and overcoming multi-drug resistance. In this study, we prepared doxorubicin submicron emulsion, and examined the stability after autoclaving, the in vitro cytotoxic activity, the intracellular accumulation and apoptpsis of doxorubicin submicron emulsion in MCF-7/ADR cells. ...

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, ...

Access to antiretroviral therapy (ART) is increasing in resource-limited settings (RLS) and can successfully reduce HIV-related morbidity and mortality. However, virologic failure and development of viral drug resistance can result in reduced treatment options and disease progression. Additionally, transmission of resistant virus, and particularly multi-drug resistance, could become a public he...

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...
