  2. 11. New approaches to preparation and storage of platelets

    Author : Stella Larsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : During the last century, transfusion of blood components has become a prerequisite for treatment in many clinical settings. The availability of plastic bags and methods for centrifugation and separation of blood cells, has enabled processing of whole blood into blood cell components, and made it possible to optimize transfusion therapy, as well as storage conditions.

  4. 12. Human Fetal Hemoglobin : Biochemical Characterization and Recombinant Production

    Author : Khuanpiroon Ratanasopa; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Blood substitutes; HBOCs; HbF; recombinant hemoglobin; pseudoperoxidase; ITC; haptoglobin;

    Abstract : Blood transfusion is a common medical procedure when oxygen supply in the body is impaired. However, blood transfusion is not always without risks. The uncontrolled spreading of blood borne pathogens such as HIV or hepatitis B and C virus has urged researchers to look for “blood substitutes”. READ MORE

  5. 13. Erythrocyte deformability studies by viscometry and filtrometry

    Author : Sylvi Persson; Pavo Hedner; Bo Sandhagen; Sweden Lund University Hospital of Lund Department of Medicine; []
    Keywords : Erythrocyte deformability; viscometry; Filtrometry; Red cell membrane; Buffer; Filtration pressure; stress factors; Mean corpuscular volume; Sodium-potassium pump; Ouabain; Corticosteroids; Blood storage; Transfusion; MEDICINE; MEDICIN;

    Abstract : DOCTORAL DISSERTATION  Abstract The present thesis concerns factors of major importance in filtrometric studies of human erythrocytes, e.g. influence of buffer media, importance of filtration pressure for filtration through micropores and possible effects of damaged and hemolyzed blood cells.

  6. 14. Haemostatic changes in plasma for transfusion during preparation and storage

    Author : Anna-Maija Suontaka; Karolinska Institutet; Karolinska Institutet; []
    Keywords : transfusion plasma; cold activation; contact system; coagulation; fibrinolysis; citrates; methylene blue; fibrinogen; stability;

    Abstract : The haemostatic quality of plasma for transfusion is liable to be affected by techniques for preparation and storage. We have studied changes in the contact system, coagulation and fibrinolysis under the following conditions: blood drawn into a half-strength citrate anticoagulant solution, virus inactivation of plasma with methylene blue and red light, and plasma storage in the fluid phase.

  7. 15. Prevention of hemolysis as a novel strategy to limit hemoglobin-mediated lipid oxidation in fish - towards a more sustainable use of fish raw materials

    Author : Semhar Ghirmai; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hemoglobin; herring Clupea harengus ; fish; rainbow trout Oncorhynchus mykiss ; erythrocyte; hemolysis; side-stream; antioxidant; lipid oxidation; blood plasma;

    Abstract : Hemoglobin (Hb) has been recognized as a main pro-oxidant in fish, causing fast and intense lipid oxidation. This thesis explores the hypothesis that maintaining red blood cells (RBCs) intact for an extended time during fish processing could delay Hb-mediated lipid oxidation. READ MORE
