  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. Proteins of the Inter-α-inhibitor Family : Biosynthesis, Plasma Clearance and Interaction with Extracellular Matrix Components

    Författare :Aneta Kaczmarczyk; Erik Fries; Anders Malmström; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; bikunin; inter-α-inhibitor; pre-α-inhibitor; intracellular processing; plasma clearance; extracellular matrix; binding; collagen; Biokemi; Biochemistry; Biokemi; Medical Biochemistry; medicinsk biokemi;

    Sammanfattning : Bikunin, a chondroitin sulfate-containing protein of 25 kDa, has protease inhibitory activity and occurs in the plasma in free and complexed form. In inter-α-inhibitor (IαI) and pre-a-inhibitor (PαI) it is covalently linked through its chondroitin sulfate (CS) chain to two or one other polypeptide of about 80 kDa – heavy chains 1 and 2 (H1, H2) and heavy chain 3 (H3) – respectively.

  4. 3. Radiolabeled acetate PET in oncology imaging : studies on head and neck cancer, prostate cancer and normal distribution

    Författare :Aijun Sun; Jens Sörensen; Silvia Johansson; Mikael Karlsson; Katrine Åhlström Riklund; Ingela Turesson; Heikki Minn; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 11C-acetate; 18F-fluoroacetate; PET; head and neck cancer; staging; delineating tumor volume; clearance rate; perfusion; RT; treatment outcome; benign and malignant lymph node; prostate cancer; normal distribution; Oncology; Onkologi; onkologi; Oncology;

    Sammanfattning : The use of positron emission tomography (PET) for imaging in oncology has grown rapidly in recent years. 2-[18F]-fluorodeoxyglucose (FDG) is the most common tracer of PET, although drawbacks exist. LÄS MER

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

    Författare :Lars Hjorth; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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

  7. 5. Frictional studies and high strain rate testing of wood under refining conditions

    Författare :Birgitta Svensson; Hans Höglund; Per A. Gradin; Mittuniversitetet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Friction; High strain rate testing; Wood; Mechanical pulping; Tribology; Refining; Energy consumption; Chemical engineering; Kemiteknik;

    Sammanfattning : When producing thermomechanical pulps (TMP), wood chips and fiber material are loaded mechanically in a disc-refiner to separate the fibers and to make them flexible. In the process, much of the energy supplied is transferred to the fiber material through cyclic compression, shear and friction processes. LÄS MER
