  1. 6. Development of New Methodology in Organic Synthesis: Lewis Acid-Mediated Rearrangements of Ammonium Ylides and Addition of 1, 3-bis(silyl) propenes to Aldehydes

    Författare :Pavel Tuzina; Peter Somfai; Ari Koskinen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; asymmetric; amino acid; ammonium ylide; Lewis acid; microwave irradiation; Organic synthesis; Organisk syntes;

    Sammanfattning : This thesis deals with the development of new methodologies in organicsynthesis. The main focus is on the development of Lewis acid-mediated [1,2]-rearrangements of ammonium ylides and the novel addition of 1,3-bis(silyl)propenes to carbonyl compounds. LÄS MER

    Sammanfattning : The gastrointestinal tract (GIT) regulates nutrient uptake, secretes hormones and has a crucial gut flora and enteric nervous system. Of relevance for these functions are the G protein-coupled receptors (GPCRs) and the solute carriers (SLCs). LÄS MER

  4. 8. Amino acid-induced thermogenesis during anaesthesia

    Författare :Eva Brzezinska Selldén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : General anaesthesia causes hypothermia due to decreased metabolic rate and impaired thermoregulation. Adverse effects of hypothermia are coagulation disorders, wound infection, ischemic cardiac events and postoperative shivering. LÄS MER

  5. 9. In vivo analysis of amino acid permease folding in yeast

    Författare :Andreas Ring; Per O. Ljungdahl; George Diallinas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nutrient sensing; signal transduction; endoprotease; subcellular fractionation; membrane-localized chaperone; amino acid permease; endoplasmic reticulum; membrane protein folding; Saccharomyces cerevisiae; Cell Biology; cellbiologi;

    Sammanfattning : Plasma membrane (PM) proteins are critical for cells to respond to environmental cues, such as the availability of nutrients. The yeast Saccharomyces cerevisiae is able to sense extracellular amino acids using the SPS sensing system. LÄS MER
