PURPOSE We performed a prospective comparison of the use of twinkling color Doppler ultrasound and noncontrast computerized tomography in the diagnosis of renal colic in emergency room patients. MATERIALS AND METHODS A total of 815 consecutive adult patients with suspected renal colic presented to the emergency room and were evaluated immediately with color Doppler ultrasound and noncontrast ...

[1] The rapid intensification and decay in Hurricane Charley (2004) was sampled by the WSR-88Ds in Key West and Tampa. Charley’s axisymmetric wind fields, vertical vorticity, perturbation pressure, and reflectivity were derived from the ground-based velocity track display (GBVTD) technique. Charley’s rapid intensification was accompanied by a contracting eyewall. The central pressure dropped 33...

The cells of the intestinal epithelium provide a selectively permeable barrier between the external environment and internal tissues. The integrity of this barrier is maintained by tight junctions, specialised cell-cell contacts that permit the absorption of water and nutrients while excluding microbes, toxins and dietary antigens. Impairment of intestinal barrier function contributes to multip...
