background and objectives : resistance among bacterial isolates is the leading cause of increased mortality and morbidity worldwide. carbapenems once thought to be effective are becoming ineffective mostly due to the emergence of carbapenemase. this study was designed to determine in vitro efficacy of modified hodge test for detection of carbapenemase production in gram negative rods. material ...

BACKGROUND Safety assessment of genetically modified organisms is currently often performed by comparative evaluation. However, natural variation of plant characteristics between commercial varieties is usually not considered explicitly in the statistical computations underlying the assessment. RESULTS Statistical methods are described for the assessment of the difference between a geneticall...

Unlike most other jurisdictions, the USA decided to adapt pre-existing legislation to encompass products of biotechnology. In so doing, it established an overarchi...

We report here a preliminary value for the πNN coupling constant deduced from the GMO sumrule for forward πN scattering. As in our previous determination from np backward differential scattering cross sections we give a critical discussion of the analysis with careful attention not only to the statistical, but also to the systematic uncertainties. Our preliminary evaluation gives g c (GMO) = 13...
