  1. 1. Signal transduction in the brain : modulation of receptor-mediated inositol phospholipid breakdown by potassium and fluoride ions

    Author : Gunnar Tiger; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inositol phospholipid breakdown; muscarinic receptors; potassium; fluoride; rat brain; pig brain;

    Abstract : Neurotransmitter receptor types mediating the generation of intracellular signals are of two types; ligand-gated ion channels and G protein coupled receptors. The effector enzyme phosphoinositide-specific phospholipase C (PLC) is modulated by stimulation of G protein coupled receptors, leading to an increased breakdown of inositol phospholipids ("Ptdlns breakdown").

    Abstract : A method based on ingrowth mesh bags was developed to study the production of EMM. These bags were made of nylon mesh with a mesh size of 50 mu-m, which allows colonisation by fungal mycelia but excludes the tree roots. READ MORE

  5. 5. Inorganic ions in wood chips- Leaching prior to Kraft pulping and effect of calcium on Kraft delignification

    Author : Anna Saltberg; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; calcium; Scandinavian softwood; Keywords: Kraft pulping; potassium; birch; eucalyptus; aspen; acidic leaching; oxalate.;

    Abstract : Wood is the main source of Non-Process Elements (NPEs), such as, calcium, potassium, manganese and chloride in Kraft pulp mills. Due to the recirculation of cooking chemicals and water, process disturbances related to the accumulation of NPEs in the process streams are inevitable. READ MORE
