To study if the severity of hypertension could be associated with disturbances of the autoregulation of renal blood flow and glomerular filtration, we compared the renal hemodynamic and functional responses to acute blood pressure reductions of a group of patients with moderate essential hypertension (n = 10) with those of a group of patients with severe hypertension (n = 10). Blood pressure wa...

Background & Aims of the Study: In some situation like rainfall seasons raw water become very turbid so it affected the water treatment plant processes and quality of produced water. Treatment of very high turbid water has some concerns like precursors for disinfection by-products and very loading rate of particle on filter's media and consequently increases in water consumptio...

An increasing interest in the rheological properties of Red Blood Cell (RBC) has arisen during the last decade and the Erythrocyte Deformability (ED.) has been recognized as a crucial property at the microcirculation level. Many techniques have been proposed to measure this parameter. Whole blood techniques (such as Teitel’paper filter or Reid & Dormandy’s) may have some interest in the sense t...

Microalbuminuria is a known marker of subclinical organ damage. Its prevalence is higher in patients with resistant hypertension than in subjects with blood pressure at goal. On the other hand, some patients with apparently well-controlled hypertension still have microalbuminuria. The current study aimed to determine the relationship between microalbuminuria and both office and 24-hour ambulato...

For the purpose of measuring flow and pressure characteristics oil filters used in vehicles with internal combustion engines, a laboratory test equipment was used, which designed at Department Transport Handling Slovak University Agriculture Nitra. The target information from given measurement is obtained data on change pressure, based type filter used. contribution this paper that can be futur...

Blood pressure is a marker of elevated risk for cardiovascular disease, even within the normotensive range. The present study evaluates cardiorenal modifications observed in normotensive (<140/90 mm Hg) subjects. Using World Health Organization-International Society of Hypertension definitions, 265 normotensive subjects were categorized as having optimal (n=73), normal (n=84), and high-normal (...

BACKGROUND Strict glycaemic control has been shown to reduce the risk of developing diabetic nephropathy. In established nephropathy, however, the impact of glycaemic control on prognosis is less clear. Therefore we investigated the effect of long-term glycaemic control on the decline in renal function in insulin-dependent diabetic patients with overt nephropathy. METHODS The study was perfor...

In recent studies in this laboratory employing normal hydropenic rats we have demonstrated that the reduction in absolute proximal reabsorption that attends the experimental reduction of single nephron glomerular filtration rate (SNGFR) (glomerulotubular balance) is mediated, at least in part, by the accompanying decline in postglomerular vascular protein concentration, and therefore, postglome...
