  1. 6. Heavy Metal Superantigen : Genetic Regulation of Lymphocyte Activation by HgC12

    Författare :Yun Jiang; Peter Mathieson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; immunologi; Immunology;

    Sammanfattning : Injections of subtoxic doses of HgCl2 (mercuric chloride) cause a systemic autoimmune disease in genetically predisposed rats and mice. My work was designed to elucidate how HgCl2 induces lymphocyte activation and how the response to HgCl2 is regulated in susceptible and resistant strains. LÄS MER

  3. 7. Protein-based capacitive biosensors for the detection of heavy-metal ions

    Författare :Alessia Mortari; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy metal ions; protein; electrode; Biosensor; capacitance;

    Sammanfattning : Some metal ions, such as copper and zinc, are essential nutrients and catalysts in biochemical reactions. Other metal ions, e.g. cadmium and mercury, are highly toxic elements. LÄS MER

  4. 8. Microbial remediation of heavy metal ion polluted soil and water

    Författare :Torbjörn Håkansson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EDTA; metal; soil; remediation; Sulphate reducing bactera; biogas; water;

    Sammanfattning : Contamination of soil and water by heavy metal ions (HMs) is a problem all over the world.The use of biological methods alone or in combination with other techniques for treatment of such polluted sites constitutes a major challenge. LÄS MER

  5. 9. Self-assembly of amyloid-β peptides in the presence of metal ions and interacting molecules – a detour of amyloid building blocks

    Författare :Cecilia Mörman; Astrid Gräslund; Daniel Otzen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biophysics; Alzheimer’s disease; protein aggregation; amyloid formation; amyloid-β peptide; aggregation kinetics; interactions; metal ions; designed peptide constructs; Tau protein; NMR; circular dichroism; fluorescence spectroscopy; Biophysics; biofysik;

    Sammanfattning : Misfolding of proteins into amyloid structures is implicated as a pathological feature in several neurodegenerative diseases and the molecular causes are still unclear. One typical characteristic of Alzheimer’s disease is self-assembly and accumulation of soluble amyloid-β (Aβ) peptides into insoluble fibrils and plaques. LÄS MER
