  1. 6. Role of phospholipids in neurodegenerative diseases

    Författare :Zhi-Zhong Guan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The structure and composition of brain phospholipids, including also their ether analogues, were investigated and modifications during neurodegeneration were analysed. In order to improve sensitivity and reproducibility, new HPLC methods were developed for separation and quantitation of phospholipids and plasmalogens, followed by quantitation of fatty acids and aldehydes.

  3. 7. Copepods in Skeletonema-dominated food webs : Toxicity and nutritional quality as factors controlling copepod-diatom interactions

    Författare :Roswati Md Amin; Ulf Båmstedt; Sigrun Jónasdóttir; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Copepod-diatom interaction; toxicity; nutritional quality; Skeletonema;

    Sammanfattning : My thesis focuses on copepod-diatom interactions, specifically on the effects of food quality and toxicity on copepod feeding, reproductive success and behavior but as a frame, also includes a quantitative evaluation of copepod carbon requirements compared to other trophic plankton groups. My aim was to evaluate the function of copepods in diatom-dominated spring blooms. LÄS MER

  4. 8. Food ingredients from cultivated seaweeds-Improving storage stability and protein recovery

    Författare :Hanna Harrysson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; unsaturated fatty acids; macroalgae; alterative cultivation; sequential recovery; pH-shift; ascorbic acid; long-term storage; Seaweed; protein extraction; proteins; lipid oxidation;

    Sammanfattning : There is a global demand for new vegetarian protein sources, and seaweed have for multiple reasons been identified as a promising candidate. The overall aim of this thesis was to evaluate the potential of three different Swedish seaweed species as food protein sources, but also as sources of unsaturated fatty acids, vitamins and minerals.

  5. 9. Valorization of herring filleting co-products to silage - Control of protein hydrolysis and lipid oxidation during ensilaging and possibilities for separating herring silage into multiple products

    Författare :Mursalin Sajib; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; separation; silage; pilot-scale; lipid oxidation; Herring Clupea harengus ; protein hydrolysis; ensilaging; antioxidants; fish oil; valorization; by-products;

    Sammanfattning : Industrial processing of herring ( Clupea harengus ) into convenience products such as fillets generates around 60% co-products being rich in both protein and n-3 polyunsaturated fatty acids (PUFAs). A promising cost-efficient strategy to valorize these raw materials into food and/or feed ingredients would be to apply ensilaging, i.e. LÄS MER

  7. 10. The effects of reactive oxygen species and lipofuscin on the function and health of the retinal pigment epithelium

    Författare :Ulf Wihlmark; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Age-related macular degeneration (ARJVID) is a common cause of central vision loss in elderly people. Specific treatment is possible only for selected patients. A dysfunction of the retinal pigment epithelial (RPE) cells has been proposed to help explain the pathogenesis of ARMD. LÄS MER
