Optimization of the reconstruction interval in neurovascular 4D-CTA imaging. A technical note.

Time resolved whole brain CT angiography (4D-CTA) is a novel imaging technology providing information regarding blood flow. One of the factors that influence the diagnostic value of this examination is the temporal resolution, which is affected by the gantry rotation speed during acquisition and the reconstruction interval during post-processing. Post-processing determines the time spacing between two reconstructed volumes and, unlike rotation speed, does not affect radiation burden.

Evaluation of a New Dip-Stick Test for the Rapid Detection of Salmonella in Food.

A new commercial dip-stick method (PATH-STIK) for the rapid detection of Salmonella was evaluated. The test is based on immunochromatographic technology, known from simple clinical diagnostics like the human chorionic gonadotropin (hCG) pregnancy tests. Results can be obtained 10 min after completion of the Salmonella enrichment procedure.

Monoclonal antibodies that detect live salmonellae.

Nine immunoglobulin G and nine immunoglobulin M murine monoclonal antibody-producing hybridomas reactive with live Salmonella bacteria were obtained from several fusions of immune spleen cells and Sp2/0 myeloma cells. The antibodies were selected by the magnetic immunoluminescence assay. The monoclonal antibodies were reactive with serogroups A, B, C1, C2, D, E, and K and Salmonella choleraesuis subsp.
