In a batch of barley associated with field cases of mycotoxic porcine nephropathy and containing ochratoxin A and citrinin, the mycoflora were isolated by parallel incubation at 10 and 25 degrees C. Subsequently, the isolated cultures were checked for production of nephrotoxins (xanthomegnin, viomellein, ochratoxin, and citrinin). The nephrotoxin producers,(More)
The mycotoxin fusarochromanone, a metabolite of Fusarium fungi, is able to induce tibial dyschondroplasia (TD) in chickens under experimental conditions. On the basis of health surveillance data on TD, two broiler farms with TD prevalence rates of up to 56% were identified. In the corresponding pelleted feed samples, fusarochromanone was detected in all 12(More)
The impact and expectation of cost-justifying patient safety IT initiatives using a traditional ROI must evolve to focus beyond the financial benefit. It must encompass overall patient safety, patient satisfaction, and employee and physician satisfaction benefit categories. Computerized physician order entry (CPOE) and bar code medication administration(More)
[1] We present a new approach for studying the inner core rotation and its variability by separating the underlying structure from its time evolution. This is achieved by fitting a large set of existing seismic BC‐DF traveltime data with a smoothing spline analysis, which is implemented in the statistics package R. This method allows us to separate the(More)
We have developed a fluorescent-based system for detecting low-level anayltes in point -of-care and critical care settings. The goals of the design were: 1) high sensitivity, comparable to present clinical chemistry analyzers, 2) rapid response times (5 minutes) with little operator attention, and 3) disposable, one-shot sample modules. We achieved these(More)
