Malathion resistance in the red ßour beetle, Tribolium castaneum (Herbst), is a worldwide problem and is very stable once it becomes widespread in natural populations. In the absence of insecticide the proportion of resistant phenotypes may rapidly decline but the development of resistance does not always involve reduced Þtness. Malathion-speciÞc resistance in T. castaneum seemsnot to involve a...
Introduction: Since there has been a dearth of research on the assessment of CYP2C19 polymorphism in the east of Iran (Khorasan provinces), this study aimed to detect, CYP2C19*2 and CYP2C19*3 allele frequencies among patients with coronary artery disease. The participants were selected among those referring to Emam Reza Hospital, Mashhad, Iran. Furthermore, the current research was motivated to...
In response to the widespread use of control strategies such as Insecticide Treated Nets (ITN), Anopheles mosquitoes have evolved various resistance mechanisms. Kdr is a mutation that provides physiological resistance to the pyrethroid insecticides family (PYR). In the present study, we investigated the effect of the Kdr mutation on the ability of female An. gambiae to locate and penetrate a 1c...
Background and Aim: Ciprofloxacin-resistant Salmonella spp. are among the most important causative agents of food-borne infections. The marA efflux pump in this bacterium plays a significant role in the development of drug resistance. The aim of this study was to investigate marA efflux pump gene expression in Ciprofloxacin resistant Salmonella enteritidis clinical strains by Real Time PCR. Mat...
BACKGROUND TR-700 is the active moiety of TR-701 (DA-7157), a new oral/intravenous oxazolidinone prodrug. We examined its activity against linezolid-susceptible and -resistant staphylococci and enterococci. METHODS MICs were determined by the CLSI agar dilution method. RESULTS MICs of TR-700 were tightly clustered around 0.5 mg/L for linezolid-susceptible staphylococci and enterococci compa...
Many mechanisms have been proposed to explain cisplatin resistance, suggesting that this phenomenon is multifactorial. In an attempt to define the chromosome(s) responsible for cisplatin resistance in the human ovar ian carcinoma 2008/C13* cell lines, somatic cell hybrids were obtained following fusion of the cisplatin-resistant 2008/C13* cells with an A9 rodent fibroblast cell line. The hybrid...
