  1. 1. 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

  5. 4. Systems-level characterization of probiotic bifidobacteria - Towards rational optimization of industrial production

    Författare :Marie Schöpping; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; genome-scale metabolic modeling; stability; robustness; industrial manufacturing; bifidobacteria; stress-associated genes; probiotics; nutritional requirement; interspecies variations;

    Sammanfattning : Probiotic Bifidobacterium strains contribute to a healthy gut microbiota of their hosts. Increasing public awareness of this positive effect has resulted in a growing demand for these microorganisms. LÄS MER

  7. 5. Assessment and prognostic importance of nutritional status and body composition in liver transplantation

    Författare :Catarina Lindqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Chronic liver disease and liver cirrhosis are progressive diseases closely linked to metabolism and nutritional status. Weight loss is a result of negative energy balance and is therefore a good measure of risk of malnutrition. LÄS MER
