  1. 1. 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

  3. 2. Towards a detailed understanding of the red blood cell storage lesion : and its consequences for in vivo survival following transfusion

    Författare :Andreas Hult; Christer Malm; Per-Arne Oldenborg; Martin L. Olsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Red blood cell; erythrocyte; transfusion; macrophage; phagocytosis; storage lesion; eryptosis; Class A scavenger receptor; transfusion medicine; transfusionsmedicin;

    Sammanfattning : Red blood cells (RBCs) are vital for oxygen delivery to tissues and constitute the vast majority of all cells in blood. After leaving the red bone marrow as mature cells, RBCs have a lifespan of approximately 120 days before they are removed from the circulation by macrophages, mainly in the spleen and liver. LÄS MER

  4. 3. Elucidating Genetic and Biochemical Aspects of the P1 and Sda Carbohydrate Histo-Blood Group Antigens

    Författare :Linn Stenfelt; Avdelningen för hematologi och transfusionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood Group; P1 antigen; Sda antigen; A4GALT; B3GALNT2; glycosyltransferase; red blood cell; transfusion medicine;

    Sammanfattning : Human histo-blood groups are inherited polymorphic variants that occur in the molecular structures on the humanred blood cell (RBC) surface. Introducing foreign RBCs into a recipient lacking an antigen may activate the humoraldefence leading to a hemolytic transfusion reaction. LÄS MER

  5. 4. High-resolution Imaging of Cleared and Expanded Kidney Tissue Samples

    Författare :David Unnersjö Jess; Hans Blom; Hjalmar Brismar; Lena Scott; Karlhans Endlich; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kidney; Renal Pathology; Microscopy; Super-resolution microscopy; Tissue expansion; Foot processes; Glomerular filtration; Podocytes; Biological Physics; Biologisk fysik;

    Sammanfattning : The kidney is one of the most important and complex organs in the humanbody with the task of filtering hundreds of litres of blood daily. It is responsiblefor the salt and acid/base balance in the body, as well as secretinghormones important for red blood cell production and blood pressure regulation. LÄS MER

  7. 5. Microfluidic Cell and Particle Sorting using Deterministic Lateral Displacement

    Författare :Stefan Holm; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microfluidics; Separation science; Deterministic Lateral Displacement; Cell analysis; Deterministic lateral displacement; Microfluidics; Particle sorting; Droplet microfluidics; trypanosomiasis; red blood cell; Cell sorting; Fysicumarkivet A:2018:Holm;

    Sammanfattning : Microfluidics is a field which has the potential to revolutionize medical diagnostics. The ability to sort and analyse cells by the use of portable handheld devices has the potential to enable sensitive devices for point-of-care diagnostics. LÄS MER
