  1. 26. What are the effects of natural versus human-caused acidity on stream species diversity and ecosystem functioning?

    Författare :Zlatko Petrin; Björn Malmqvist; Steve J. Ormerod; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; acid rain; aquatic insects; biodiversity; ecosystem function; Biology; Biologi;

    Sammanfattning : Human activities have caused acidification of freshwater systems on a large scale resulting in reduced species diversity and ecological functioning in many lakes and streams. However, many naturally acidic freshwater systems have also been found, for instance in northern Sweden. LÄS MER

  3. 27. Post-transplantation Hypercholesterolaemia

    Författare :Osama Al Rayyes; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; thiazolidinediones; transplantation; low density lipoprotein; insulin; indomethacin; hydrocortisone; fluvastatin; flufenamic acid; Cholesterol; cyclosporine; troglitazone.; Immunology; serology; Immunologi; serologi;

    Sammanfattning : The multidrug regimen, cyclosporine, corticosteroids, and azathioprine, is used in transplantation centres to prevent organ rejection. Several clinical studies have shown that cyclosporine and corticosteroids to cause increases in low density lipoprotein (LDL)-cholesterol, with subsequent development of atherosclerosis. LÄS MER

  4. 28. Cryogels Based on Crosslinked Cells as Green Biocatalysts for Biotechnology

    Författare :Oksana Zaushitsyna; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cells; Crosslinkers; PVA PEI; Immobilization; Biocatalysts; Biobased chemicals; Biotransformation; stress tolerance;

    Sammanfattning : Abstract Due to the finite nature of fossil resources and their environmental impact, such as greenhouse gases and climate change, the bio-based production of chemicals, materials and fuels is the subject of extensive research in industrial biotechnology. Biotransformation and fermentation are considered to be mild, “green” processes that make use of effective and reliable biocatalysts to provide bio-based chemicals. LÄS MER

  5. 29. Genetic modification of cholera toxin B subunit for mucosal anti-infectious or anti-pathologic vaccination

    Författare :Hamid Sadeghi; Göteborgs universitet; []
    Nyckelord :Genetic fusion protein; cholera toxin B subunit; insulin; GST; Oral tolerance;

    Sammanfattning : The development of mucosal vaccines requires antigen delivery systems that can efficiently help to present vaccine antigens to the mucosal immune system. En efficient and well known antigen carrier/delivery system is the B subunit of cholera toxin (CTB). LÄS MER

  7. 30. Nucleic acid tools for detection and characterization of biological systems

    Författare :Ioanna Smyrlaki; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Nucleic acids, DNA and RNA, are naturally occurring biopolymers synthetized by cells to store and propagate genetic information. They can be found in eukaryotic cells, bacteria, archaea and viruses and, thanks to the development of synthetic chemistry techniques, they can be synthetized with relative ease on demand in the laboratory.
