  2. 1. Voltage-dependent anion channels (VDAC) in the plasma membrane induce apoptosis

    Author : Nesar Akanda; Fredrik Elinder; Tuula Jalonen; Linköpings universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Physiology; Apoptosis; Cell membrane; Hippocampus; Membrane potentials; Neurons; Voltage-dependent anion channels; Medicine; Medicin;

    Abstract : Apoptosis, or programmed cell death, is essential for proper development and functioning of the body systems. During development, apoptosis plays a central role to sculpt the embryo, and in adults, to maintain tissue homeostasis by eliminating redundant, damaged or effete cells. Therefore, a tight regulation of this process is essential. READ MORE

  4. 2. Environmentally relevant chemical disruptors of oxidative phosphorylation in Baltic Sea biota : Exposure and toxic potentials

    Author : Anna-Karin Dahlberg; Lillemor Asplund; Åke Bergman; Göran Marsh; Patrik Andersson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oxidative phosphorylation; OH-PBDEs; MeO-PBDEs; PBDEs; long-tailed duck Clangula hyemalis ; Baltic herring Clupea harengus ; Baltic blue mussel Mytilus trossulus x Mytilus edulis ; Baltic Sea; miljökemi; Environmental Chemistry;

    Abstract : This thesis focuses on toxicity and occurrence of hydroxylated polybrominated diphenyl ethers (OH-PBDEs) in Baltic Sea biota. The aims were to assess OH-PBDEs potency for disruption of oxidative phosphorylation (OXPHOS) and determine their and related compounds exposure in Baltic blue mussel, herring and long-tailed duck.

  5. 3. Aspects on luminal nitric oxide in relation to oesophageal acid exposure and mucosal integrity

    Author : Mogens Bove; Göteborgs universitet; []
    Keywords : nitric oxide; nitric oxide synthase; acid; gastro-esophageal reflux disease; membrane potentials; saliva; nitrate; blood flow; ferret; histopathology;

    Abstract : Nitric oxide (NO) exerts important neuromuscular control of the oesophagus, but little is known about the sources and effects of the NO present in the distal oesophageal lumen. These questions were presently addressed in both human and animal experiments. READ MORE

  6. 4. NMR Investigations of Peptide-Membrane Interactions, Modulation of Peptide-Lipid Interaction as a Switch in Signaling across the Lipid Bilayer

    Author : Sofia Unnerståle; Lena Mäler; Göran Widmalm; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; peptide-lipid interaction; membrane mimetic; NMR; biophysics; Molecular biophysics; Molekylär biofysik; biofysik; Biophysics;

    Abstract : The complexity of multi cellular organisms demands systems that facilitate communicationbetween cells. The neurons in our brains for instance are specialized in this cell-cellcommunication. READ MORE
