introduction: serum c-reactive protein (crp) is believed to be increased in metastatic urothelial cancer of the bladder. however, the changes depend on the stage and grade of the upper tract urothelial carcinoma (utuc). this study aimed to compare low-range and high-range serum crp and haptoglobin in new cases of utuc. materials and methods: blood was collected from newly diagnosed patients wit...

there is just one study about the effects of 830 nm low power laser (lpl) on conduction velocity of sural nerve in human. considering the fact that the sural nerve is a pure sensory nerve, therefore, for determining the effect of lpl on electrophysiological parameters of the nerve in human, this study was carried out as a base for further basic and clinical researches. thirty eight normal volun...

Perforation of a hollow viscus is an acute abdominal drama and the accurate diagnosis highly depends on demonstration of free intra­pritoneal air. The importance of adequate examination in the demonstration of ,tiny amount ()ff air is stressed and the value of an upright chest film when the horizontal beam is tangential to the top of the diaphragm is mentioned. Before standing for chest x-ray t...

A linear, aeroelastic analysis of a low aspect ratio swept back trapezoidal wing modeled as a cantilever plate is presented. An analytical and numerical formulation for both the aerodynamic forcing and structural response of the wing was developed. The analytical model uses a three dimensional time domain vortex lattice aerodynamic method. A Rayleigh-Ritz approach has been used to transfer equa...
