  3. 17. Flagellates in the marine microbial food web : the ecology of a mixotrophic nanoflagellate, Ochromonas sp

    Författare :Agneta Andersson-Nordström; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbial food web; flagellates; Ochromonas sp.; mixotrophy; size- selective grazing; remineralisation; excretion of DFAA;

    Sammanfattning : Nanoflagellates were found to be abundant in a coastal area of the northern Bothnian Sea. The maximum concentration of nanoflagellates, approximately 8000 cells ml-1, was observed in July, coinciding with a decrease in the abundance of cyanobacteria. LÄS MER

  4. 18. Melatonin secretion and excretion : a clinical study focusing on factors and disease states which might influence melatonin

    Författare :Johan Wikner; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Melatonin; ethanol; Wernicke-Korsakoff syndrome; calcium; calcium channel blocker; verapamil; 6-sulphatoxy-melatonin; Obstructive Sleep Apnea Syndrome; Continuos Positive Airway Pressure; Fibromyalgic syndrome; TSH; somatostatin; octreotide; GH; Hypothyroidism;

    Sammanfattning : The overall aim of this thesis was to find out whether other factors than the the light-dark changes influence the function of the pineal gland. Since melatonin (MT) itself, or its precursor serotonin, are of importance for sleep, mood, and pain perception, disease states - or situations in which these functions are disturbed - should be of interest to investigate in this context.

  5. 19. Sugar consumption and cardiometabolic risk. With a focus on the urinary sucrose and fructose biomarkers

    Författare :Stina Ramne; Nutritionsepidemiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Added sugar; Sugar-sweetened beverages; Cardiometabolic risk; Type 2 diabetes; Cardiovascular disease; Urinary sugar biomarker; Sucrose and fructose excretion; Gut microbiota; Plasma proteome;

    Sammanfattning : Introduction: In contrast to the intake of sugar-sweetened beverages (SSBs), the evidence linking added sugar intake to the risk of cardiometabolic disease (primarily referring to cardiovascular disease and type 2 diabetes (T2D)) is contradictory. Aim: The aim of this thesis is to elucidate the role of added sugar intake in the risk for cardiometabolic diseases. LÄS MER

  7. 20. Evaluation of polysucrose 15000 as a marker of intestinal permeability

    Författare :Hans Öman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Polysucrose Permeability Intestinal Absorption Cell Memhrane Permeahility Molecular WeightMacromolecular systems Biological Markers Biological Transport Crohn Disease Arthritis; RheumatoidAnti-lnflammatory Agents; Non-Steroidal Chromium Radioisotop;

    Sammanfattning : Polysucrose (PS) is a synthetic copolymer of sucrose and epichlorohydrin, which can be produced in a variety of molecular sizes. The aim of the study was to evaluate the functionality of PS 15000, mean mol wt 14700, as a marker for intestinal permeability to macro molecules. LÄS MER
