  1. 11. Glutathione reductase from erythrocytes : purification, characterization and identification of functional histidine and arginine residues of the enzyme

    Författare :Vijayakumar Boggaram; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This investigation aims at the development of a rapid, simple purification procedure for glutathione reductase and at an exploration of the chemical groups of the enzyme essential for activity.Glutathione reductase from porcine erythrocytes was purified to homogeneity by the use of affinity chromatography on 2’,5’ ADP-Sepharose 4B.

    Sammanfattning : Islet transplantation has found its niche in diabetes treatment. It has contributed to a better quality of life and better glycemic control of patients with diabetes suffering from severe hypoglycemia that are not eligible for vascularized pancreas transplantation. Islet isolation is a technically challenging procedure. LÄS MER

  5. 14. Cellular Origin and Development of Glioma

    Författare :Nanna Lindberg; Lene Uhrbom; Bengt Westermark; Kristian Pietras; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioma; brain tumor; PDGF; RCAS TV-A; cell of origin; glial cell; oligodendrocyte progenitor cell; DNA repair; homology-directed repair; RAD51; angiogenesis; histidine-rich glycoprotein; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi; Molecular Medicine; molekylär medicin genetik och patologi ;

    Sammanfattning : Gliomas are the most common primary tumors of the central nervous system believed to arise from glial cells. Invasive growth and inherent propensity for malignant progression make gliomas incurable despite extensive treatment. LÄS MER
