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

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

    Sammanfattning : 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").

    Sammanfattning : The use of biomass as a renewable source of energy has been increasing over the past few decades, and biomass is regarded as a promising replacement for fossil fuels. Thermochemical conversion of biomass is a common approach for biomass utilization with a relatively short conversion time. LÄS MER

  7. 5. The Growth of External Ectomycorrhizal Mycelia in the Field in Relation to Host Nutrient Status and Local Addition of Mineral Sources

    Författare :David Hagerberg; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant ecology; Potassium; Phosphorus; Norway spruce; Picea abies; Whole-tree harvesting; Ectomycorrhizal fungi; Wood ash fertilization; Växtekologi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : 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. LÄS MER
