Clear similarities between antibiotic resistance islands in the chromosomes of extensively antibiotic-resistant isolates from the two dominant, globally distributed Acinetobacter baumannii clones, GC1 and GC2, suggest a common origin. A close relative of the likely progenitor of both of these regions was found in R1215, a conjugative IncM plasmid from a Serratia marcescens strain isolated prior...

Sir, Isolates from a collection of 177 antibiotic-resistant Acinetobacter recovered at Westmead Hospital, Sydney over the period 1995– 2002 were further characterized. The relationships among these isolates had previously been examined by PFGE of ApaI-digested DNA, determination of MICs of several antibiotics and PCR screening to determine whether the blaOXA-23 gene or class 1 integrons were pr...

Abstract Introduction Glutaminolysis, beside glycolysis, is a key metabolic pathway of cancer cell that provides energy and substrates for the synthesis nucleic acids, proteins, lipids. The mediated by both mitochondrial cytosolic enzymes. Neither expression glutaminolysis enzymes in colon cells nor influence various oxygen concentrations on their has been studied so far. Objectives aim study w...

Acinetobacter baumannii is an important nosocomial pathogen that often complicates treatment because of its high level of resistance to antibiotics. Though plasmids can potentially introduce various genes into bacterial strains, compared to other Gram-negative bacteria, information about the unique A. baumannii plasmid repertoire is limited. Here, whole genome sequence data was used to determin...

The radiometric gains of the AATSR visible to shortwave-infrared channels are calibrated using an on-board solar diffuser. The on-board calibration is supported by vicarious techniques such as comparisons over stable desert targets to establish relative biases in the radiometric calibrations of AATSR and other optical sensors and also to determine the long-term drifts. The authors present the r...
