in this paper, the goursat problem of a general form for a linear partial differential equation is investigated with the help of the riemann function method. some results are given concerning the existence and uniqueness for the solution of the suggested problem.

BACKGROUND Levosimendan, a calcium sensitizer, increases the sensitivity of the heart to calcium, thus increasing myocardial contractility without a rise in intracellular calcium. It was recently shown that levosimendan is beneficial in improving renal function. However, it remains to be established that the beneficial effect is differentially related to renal status during index event. OBJEC...

The precise measurement of glomerular filtration rate (GFR) and renal plasma flow (ERPF) usually requires continuous intravenous administration of adequate substances, with multiple blood and urine analysis, and does not allow measurement of separate renal function. Schlegel et al. and Gates described isotopic methods for the measurement of global and unilateral GFR and ERPF based on the determ...

(99m)Tc dimercaptosuccinic acid (DMSA) renal scans can provide accurate diagnosis of acute pyelonephritis, its sequelae (renal scars) and differential renal function (DRF). The purposes of this retrospective study were (1) to assess the relationship between DRF obtained during acute pyelonephritis and at follow-up, and (2) to elucidate the value of initial DRF in predicting subsequent renal sca...

Introduction: Nephropathy is defined as rational loss of renal function related with glomerulosclerosis and declining glomerular filtration rate. Inflammation and oxidative stress play a critical role in nephropathy. Plantago major has antioxidant effects. The aim of present study is the investigation of the effect of Plantago major hydro-alcoholic extract on the oxidative stress and renal func...

DIFFERENTIAL renal function studies during water diuresis were introduced by Howard and associates' in 1954 to aid in detection of hypertension secondary to unilateral renal disease. To enhance the diagnostic and prognostic value of such tests, many modifications in the conditions for their performance have been developed: Dustan and co-workers2 studied patients during osmotic diuresis with man...
