  2. 1. Glutamate Turnover and Energy Metabolism in Brain Injury : Clinical and Experimental Studies

    Author : Carolina Samuelsson; Elisabeth Ronne-Engström; Lars Hillered; Eva Kumlien; Carl-Henrik Nordström; Uppsala universitet; []
    Keywords : Neurosciences; glutamate; glutamine; lactate; pyruvate; microdialysis; GLT-1; energy metabolism; intracranial pressure; cerebral perfusion pressure; subarachnoid hemorrhage; ischemia; epilepsy; Neurovetenskap;

    Abstract : During brain activity neurons release the major excitatory transmitter glutamate, which is taken up by astrocytes and converted to glutamine. Glutamine returns to neurons for re-conversion to glutamate. This glutamate-glutamine cycle is energy demanding. READ MORE

  4. 2. Uptake of and Preference for Nitrate, Ammonium and Amino Acids by Understory Species in Deciduous Forests

    Author : Magnus Zätterström; Infektionsmedicin; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Soil Science; agricultural hydrology; Lantbrukshydrologi; marklära; Fixation of nitrogen; Kvävefixering; Växtekologi; Plant ecology; wild plants.; understory; rhizosphere; preference; oak forests; NRA; nitrification; nitrate; delta15N; 15N; glutamate; glycine; drying-rewetting; amino acids; ammonium;

    Abstract : AbstractThe uptake of different nitrogen forms by understory species was studied in field and laboratory. Species of the understory in deciduous forests have previously been thought to take up and assimilate only inorganic nitrogen sources. READ MORE

  5. 3. Microglial Glutamate Transporters - Regulation of Expression and Possible Physiological Functions

    Author : Mikael Persson; Göteborgs universitet; []
    Keywords : anaphylatoxin; central nervous system; herpes simplex virus; glutamate transport; glutathione; GLT-1; lipopolysaccharide; microglia; neuroinflammation; oxidative stress; protection; tumour necrosis factor-alpha;

    Abstract : Microglia are considered as the immunocompetent cells of the central nervous system (CNS). Being the first line of defence, they have prominent roles in monitoring the homeostasis and the extracellular milieu and can rapidly and specifically react to any disturbances such as brain trauma, ischemia, neurodegenerative diseases, or infections.

  6. 4. GLIAL HEMICHANNELS: A NEW ROUTE FOR CHEMICAL COMMUNICATION IN BRAIN

    Author : Malin Stridh; Göteborgs universitet; []
    Keywords : astrocyte; antioxidant; connexin; hemichannel; glutathione; efflux; glutamate;

    Abstract : The extracellular neurochemistry determines normal brain function and the faith of neurons after insults such as stroke. This thesis concerns the effect of extracellular events related to intense neuronal stimulation and stroke, i.e. READ MORE

  7. 5. Nitric Oxide Reductase from Paracoccus denitrificans : A Proton Transfer Pathway from the “Wrong” Side

    Author : Ulrika Flock; Pia Ädelroth; Simon de Vries; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; denitrification; nitric oxide reductase; heme copper oxidase superfamily; divergent member; proton transfer; electron transfer; single turnover; spectroscopy; periplasm; glutamate; proton pathway; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Denitrification is an anaerobic process performed by several soil bacteria as an alternative to aerobic respiration. A key-step in denitrification (the N-N-bond is made) is catalyzed by nitric oxide reductase (NOR); 2NO + 2e- + 2H+ → N2O + H2O. READ MORE
