1. 1. Glomerular filtration rate in adults : a single sample plasma clearance method based on the mean sojurn time

   Författare :Margareta Gref; Kjell Karp; Börje Ljungberg; Umeå universitet; []
   Nyckelord :Clinical Physiology; klinisk fysiologi;

   Sammanfattning : Glomerular filtration rate (GFR) is a key parameter in evaluating kidney function. After a bolus injection of an exogenous GFR marker in plasma an accurate determination of GFR can be made by measuring the marker concentration in plasma during the excretion. LÄS MER

3. 2. Biomarkers of Renal Function in Acute Coronary Syndromes

   Författare :Axel Åkerblom; Stefan James; Lars Wallentin; Torbjörn Omland; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cystatin C; glomerular filtration rate; GFR; creatinine; acute coronary syndrome; ACS; kidney; renal; mortality; death; myocardial infarction; Cardiology; Kardiologi; Medicin; Medicine; Internal Medicine; Internmedicin;

   Sammanfattning : The thesis aimed to investigate cystatin C and creatinine-based estimates of glomerular filtration rate (eGFR), both at admission and during follow-up, on the combined endpoint of cardiovascular death and myocardial infarction in patients with acute coronary syndrome (ACS). We also evaluated two cystatin C assays and assessed genetic determinants of cystatin C concentrations. LÄS MER

4. 3. A Study of Renal Function in Children with Cancer

   Författare :Lars Hjorth; Lund Pediatrik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Pediatri; nefrologi; Urologi; nephrology; Urology; children; sequelae; pediatric oncology; chemotherapy; renal toxicity; malignancy; hyperfiltration; iohexol clearance; glomerular filtration rate; kidney disease; Glomerular proteinuria; tubular proteinuria;

   Sammanfattning : Evaluation of long-term side effects of treatment is important due to the growing number of childhood cancer survivors. How kidney function is affected over time needs to be clarified. LÄS MER

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

   Författare :Patrik Persson; Fredrik Palm; Peter Hansell; Bengt Rippe; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

7. 5. Functional Aspects of the Juxtaglomerular Apparatus : Control of Glomerular Filtration and Renin Release

   Författare :Johan Sällström; Erik Persson; Peter Hansell; Jürgen Schnermann; Uppsala universitet; []
   Nyckelord :MEDICINE; MEDICIN; Medical Cell Biology; Medicinsk cellbiologi;

   Sammanfattning : The juxtaglomerular apparatus (JGA) is a control unit of the kidney, that regulates glomerular filtration rate (GFR) and renin release, and hence extracellular volume and blood pressure. The tubuloglomerular feedback (TGF) mechanism is a negative feedback loop that regulates GFR. LÄS MER
