  1. 1. Cyanide and central nervous system : a study with focus on brain dopamine

    Author : Gudrun Cassel; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CNS; cyanide; dopaminergic system; convulsions; receptor binding; tyrosine hydroxylase; monoamine oxidase; extracellular release; inositol phosphate; GABA; GAD;

    Abstract : The brain is a major target site in acute cyanide intoxication, as indicated by several symptoms and signs. Cyanide inhibits the enzyme cytochrome oxidase. This inhibition causes impaired oxygen utilization in all cells affected, severe metabolic acidosis and inhibited production of energy. READ MORE

  2. 2. Pea-Protein Products for Food Applications Methods for Improving Iron and Zinc Availability

    Author : Mattias Fredrikson; Chalmers University of Technology; []
    Keywords : pea-protein; phytate; phytase-enzyme; oligosaccharides; phytate-degradation; ion chromatography; inositol-phosphate; iron and zinc availability; pea-protein purification;

    Abstract : The thesis deals with some aspects of and possibilities for the production of pea protein with improved nutritional and physiological qualities. The improved pea protein can be used as a beneficial alternative to soya protein in food applications, such as infant formula. READ MORE

  3. 3. Synthesis of inositol phosphoglycans and analogues thereof

    Author : Katinka Ruda; JS Brimacombe; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Abstract : This thesis describes the synthesis of inositol phosphoglycans (IPG) corresponding to glycosyl-phosphatidylinositol (GPI) anchors found on the cell surface of the parasite Leishmania. Synthesis of an IPG which is a putative second messenger for insulin, and of analogues thereof is also discussed. READ MORE

  4. 4. Regulation of organelle Ca²+ in individual pancreatic β-cells

    Author : Anders Tengholm; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; pancreatic b-cell; inracellular Ca2 stores; furaptra; endoplasmic reticulum; digitonin; a toxin; glucose; ATP; thapsigargin; inositol 1; 4; 5-trisphosphate; ryanodine receptors; cyclic ADP ribose; nicotinic acid adenine dinucleotide phosphate; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : The Ca2+ion plays a fundamental role in the control of a variety of cellular functions, including insulinsecretion from pancreatic β-cells. Whereas the concentration of free Ca2+ in the cytoplasm ([Ca2+]i) ismaintained at low levels (5O-100 nM), some organelles contain high concentrations of the ion. READ MORE

  5. 5. Galanin receptor ligands

    Author : Johan Runesson; Ülo Langel; Lena Mäler; Stockholms universitet; []
    Keywords : Galanin; GALP; GPCR; Agonist; GalR; Chimeric peptide; Inositol phosphate production; Receptor specificity; neurokemi med molekylär neurobiologi; Neurochemistry and Molecular Neurobiology;

    Abstract : In the nervous system galanin primarily displays a modulatory role. The galaninergic system consists of a number of bioactive peptides with a highly plastic expression pattern and three different receptors. The lack of receptor subtype selective ligands and antibodies have severely hampered the charac-terization of this system. READ MORE
