  2. 1. The Influence of the Adenosine A1-receptor on Tubuloglomerular Feedback and Renin Release

    Author : Russell Brown; A Erik G Persson; Pontus Persson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; adenosine; tubuloglomerular feedback; renin release; blood pressure; micropuncture; Fysiologi; Physiology; Fysiologi;

    Abstract : The kidneys play a vital role in the maintenance of extracellular fluid and electrolyte balance and blood pressure. Adenosine, acting through the adenosine A1-receptor (A1R), and nitric oxide have been implicated in several of the regulatory mechanisms in the kidney. READ MORE

  4. 2. Aspects of Regulation of GFR and Tubular Function in the Diabetic Kidney : Roles of Adenosine, Nitric Oxide and Oxidative Stress

    Author : Patrik Persson; Fredrik Palm; Peter Hansell; Bengt Rippe; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetes; diabetic nephropathy; glomerular filtration rate; renal blood flow; insulin; renal hemodynamics; micropuncture; oxygen; NADPH-oxidase; apocynin; streptozotocin; l-arginine; CGS21680; rats; mice; Physiology; Fysiologi; Medical Science; Medicinsk vetenskap;

    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. 3. Microcirculation in native and transplanted rodent pancreatic islets with special reference to the influence of diabetes mellitus

    Author : Per-Ola Carlsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Diabetes; pancreatic islets; islet microcirculation; microspheres; micropuncture technique; islet blood flow; islet capillary pressure; oxygen tension; transplanted islets; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : The aim of the present work was to characterize the islet microcirculation in animal models of type 1 and type 2 diabetes, as well as in islets transplanted to diabetic or normoglycemic recipients. For this purpose, a microsphere technique was evaluated and applied for measurements of islet blood flow in mice. READ MORE

  6. 4. Hydronephrosis in childhood : An experimental and clinical study

    Author : Nils Wåhlin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Hydronephrosis; experimental ureteral obstruction; tubuloglomerular feedback; renal blood flow; vasoactivre substances; pressure flow measurement; Kirurgi; Surgery; Kirurgi; kirurgi; särskilt barnkirurgi; Pediatric Surgery;

    Abstract : In this thesis the pathophysiology of hydronephrosis due to ureteropelvic junction (UPJ) obstruction was studied. The kidney adapts to obstruction by changes in renal blood flow (RBF) and glomerular filtration rate (GFR). READ MORE

  7. 5. Tissue responses and host transcriptomics in bacterial infections

    Author : Jorrit Boekel; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Bacterial infections can damage host tissue and are as such a potential threat to their hosts. To protect themselves from pathogens, hosts therefore can employ diverse immune reactions. READ MORE
