1. Renal hemodynamics in renal artery stenosis and angiotensin II-dependent hypertension. Pathophysiological and diagnostic aspects
Abstract : Patients with renovascular hypertension have a poor renal and cardiovascular prognosis. To improve the care of these patients, we need to increase knowledge about the pathophysiological mechanisms involved. READ MORE

2. Endothelium-derived substances and regional hemodynamics in experimental hypertension
Abstract : The spontaneously hypertensive rat (SHR), a model for experimental hypertension, is considered to have similarities with essential hypertension in humans. Differences between SHR and normotensive Wistar Kyoto rats (WKY) in the vascular response to endothelial-derived substances such as nitric oxide (NO) have been intensively studied in vitro. READ MORE

3. Calcium Responses in the Renal Afferent Arteriole to Angiotensin II and Norepinephrine Stimulation
Abstract : Studies were performed to investigate the influence of the vasoconstrictors angiotensin II (AII) and norepinephrine (NE) on calcium metabolism in smooth muscle cells of afferent arterioles. Fura-2 and image analysis techniques were used to evaluate calcium responses in the proximal and distal parts of afferent arterioles with attached glomeruli. READ MORE

4. Aspects of Regulation of GFR and Tubular Function in the Diabetic Kidney : Roles of Adenosine, Nitric Oxide and Oxidative Stress
Abstract : Diabetic nephropathy is the main cause for initiation of renal replacement therapy and early symptoms in patients include increased glomerular filtration rate (GFR), decreased oxygen tension and albuminuria, followed by a progressive decline in GFR and loss of kidney function. Experimental models of diabetes display increased GFR, decreased tissue oxygenation and nitric oxide bioavailability. READ MORE

5. Carbon Dioxide Pneumoperitoneum - Hemodynamic Consequences and Thromboembolic Complications
Abstract : The laparoscopic way of performing general surgical procedures was introduced all over the Western world in a few years around 1990. No previous scientific studies of the safety of this new way of performing general surgery had been undertaken. READ MORE
