A(3) adenosine receptor (AR) activation and inhibition worsen and improve, respectively, renal function after ischemia-reperfusion (I/R) injury in rats. We sought to further characterize the role of A(3) ARs in modulating renal function after either I/R or myoglobinuric renal injury. A(3) knockout mice had significantly lower plasma creatinines compared with C57 controls 24 h after I/R or myogl...

BACKGROUND We compared the LightCycler MRSA advanced test (Roche Diagnostics, Germany) with enrichment culture methods to evaluate the relative diagnostic performance of the LightCycler MRSA advanced test for active surveillance in a high-prevalence setting. METHODS A total of 342 nasal swab specimens were obtained from patients in the intensive care unit at admission and on the seventh day f...

BACKGROUND Methicillin resistant Staphylococcus aureus (MRSA) has been emerged as a nosocomial and community acquired pathogen worldwide. There are many challenges for laboratory detection of MRSA. The aim of this study was to compare different phenotypic methods with PCR based method as a gold standard for detection of mecA gene. METHODS A total of 220 clinical isolates of S. aureus which we...

The aim of this study was to determine the prevalence of Staphylococcus aureus and risk factors for the acquisition of MRSA (Methicillin Resistant Staphylococcus aureus) as the main cause of skin and soft tissue infections. S. aureus were characterized for the presence of PVL, TSST-1 and mecA genes. SCCmec typing was carried out in mecA positive strains and PFGE was performed only in these stra...

Emergence of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant coagulase-negative staphylococci (MR-CoNS) in bovine milk is a major public health concern. The primary purpose of this research was to determine molecular genetic characteristics and antibiotic resistance of staphylococcal isolates recovered from milk of mastitic cows in the Shaanxi Province in Northweste...

We evaluated Mission Execution Crew Assistant’s (MECA) crew support methods during the MARS-500 experiment (520 days). MARS-500 provided a unique test platform, because of its setting, where a small crew is isolated for a long duration simulating a manned Mars mission. Thus more prolonged or repeated usage of MECA could be tested. The evaluation focused on core support functions that concern pr...

introduction: in this study, using the phenotypic and genotypic methods, oxacillin susceptibility in staphylococcus aureus (s. aureus) strains isolated from patients at two government hospitals in ilam, iran was tested. materials and methods: out of 200 s. aureus isolates from different human clinical specimens consisting of blood (31%), wound (20%), urine (21%), catheters (7%), sputum (12%), o...
