    Sammanfattning : The world-wide intensification of agriculture has led to a decline in species richness due to land use change, isolation, and fragmentation of natural and semi-natural habitats in agricultural and forestry landscapes. As a consequence, there is a current landscape management focus on the importance of green infrastructure to mitigate biodiversity decline and preserve ecosystem functions e. LÄS MER

  3. 2. Remnant echoes of the past : Archaeological geophysical prospection in Sweden

    Sammanfattning : The aim of this thesis has been to investigate the benefits, pitfalls and possibilities of using geophysical methods in archaeological projects. This is exemplified by surveys carried out at archaeological sites in different geographical and chronological contexts. LÄS MER

  4. 3. Fatty acids induce potentially atherogenic changes in extracellular matrix proteoglycans

    Författare :Mariam Rodríguez-Lee; Göteborgs universitet; []
    Nyckelord :proteoglycans; glycosaminoglycans; fatty acids; smooth muscle cells; hepatocytes; LDL binding; remnant clearance; insulin resistance; type 2 diabetes;

    Sammanfattning : Insulin resistance and type 2 diabetes (T2D) are associated with an increased prevalence of atherosclerotic cardiovascular disease (CVD). A key step in the initiation of atherogenesis is retention of low density lipoproteins (LDL) in the intima by chondroitin sulfate (CS)-rich proteoglycans (PG). LÄS MER

  5. 4. Sources of Arachidonic Acid in Platelets, Bone, Marrow and Gastrointestinal Tract

    Sammanfattning : This study investigates pathways by which the eicosanoid precursor pools in the platelets, bone marrow and the gastrointestinal (GI) mucosa are acquired and regulated, and in this context some aspects on the interaction between triglyceride (TG)-rich lipoproteins and platelets. 1.
