  1. 1. Lead in blood. ICP-MS studies of lead in plasma, blood and erythrocyte proteins

    Författare :Ingvar A Bergdahl; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; distribution; plasma; blood; erythrocytes; lead-binding prtoeins; delta-aminlevulinic acid dehydratase; inductively coupled plasma mass spectrometry; ALAD; arbetsmiljömedicin; Occupational health; industrial medicine; Lead; toxicity; ICP-MS; Yrkesmedicin;

    Sammanfattning : An inductively coupled plasma mass spectrometry (ICP-MS) method for the determination of lead in blood plasma has been developed. The detection limit was below 0.1 microgram/liter, and the precision 5%. There was no significant difference between levels in plasma and serum. LÄS MER

  3. 2. Acoustofluidic preparation of whole blood components

    Författare :Anke Urbansky; NanoLund: Centre for Nanoscience; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; acoustophoresis; ultrasound; microfluidics; cell separation; blood; blood fractionation;

    Sammanfattning : Whole blood is rich in information about the physical state of an individual and is routinely used in a variety of clinical and research applications. In this thesis, the use of a microfluidic technique called acoustophoresis for separation of different blood components is explored. LÄS MER

  4. 3. Aspects of retransfusion of shed blood in cardiac surgery

    Författare :Björn Brondén; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CABG; cardiotomy suction; lipid microemboli; porcine study; clinical study; cystatin C; creatinine; iohexol clearance; outcome; retransfusion; transfusion; blood.;

    Sammanfattning : The use of cardiotomy suction during open heart surgery with cardiopulmonary bypass (CPB) has a long tradition and often regarded as mandatory. Recently, studies have described potentially negative effects of cardiotomy suction with activation of the complement system, enhanced inflammatory response, hemolysis and coagulopathy. LÄS MER

  5. 4. Blood Flow variations in Large Arteries due to non-Newtonian rheology

    Författare :Stevin van Wyk; Laszlo Fuchs; Staffan Lundström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blood; Rheology; Viscosity; non-Newtonian; CFD; Bifurcations; Unsteadiness; Wall Shear Stress; Atherosclerosis;

    Sammanfattning : The blood is a complex fluid that contains, in addition to water, cells, macro-molecules and a large number of smaller molecules. The physical properties of the blood are therefore the result of non-linear interactions of its constituents, which are influenced by the local flow field conditions. LÄS MER

  7. 5. Pericyte Influence on Drug Delivery Across the Blood-Brain Barrier : Implications for Therapy of Neurodegenerative Diseases

    Författare :Nebojsa Mihajlica; Margareta Hammarlund-Udenaes; Christer Betsholtz; William Elmquist; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; pericytes; pericyte-deficiency; pharmacokinetics; small-molecular drugs; drug distribution; transporters; P-glycoprotein; tyrosine kinase inhibitors; Farmakokinetik och läkemedelsterapi; Pharmacokinetics and Drug Therapy;

    Sammanfattning : The blood-brain barrier (BBB) represents a complex interface between the brain parenchyma and systemic blood circulation, strictly controlling exchange of substances between the two sites. Pericytes are mural cells located on the abluminal membrane of the brain endothelium, involved in BBB formation and maintenance. LÄS MER
