  1. 1. Impact of root and mycorrhizal exudation on soil carbon fluxes : influence of elevated CO2 and metals

    Författare :Emma M. Johansson; Patrick van Hees; Bert Allard; Phil Ineson; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amino acids; 13C; carbon cycle; ectomycorrhiza; elevated CO2; exudation; DOC; LMWOA; metal stress; monosaccharides; oxalate; Pinus sylvestris; saprotrophic fungi; soil respiration; NATURAL SCIENCES; NATURVETENSKAP; Environmental chemistry; Miljökemi; Enviromental Science; Miljövetenskap;

    Sammanfattning : The thesis concerns the behavior of root and ectomycorrhizal (ECM) exudates. In particular, the dynamics of soluble low molecular weight (LMW) organic compounds such as organic acids (LMWOAs), amino acids, monosaccharides, and dissolved organic carbon (DOC) have been studied.

  4. 3. Organic acids in root exudates and soil solutions. Importance to calcicole and calcifuge behaviour of plants

    Författare :Lena Ström; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nutrient-solubilisation; iron; phosphate; nutrient-limitations; citrate; oxalate; organic acids; root exudation; acidifuge; Calcicole; calcifuge; adaptations.; Plant ecology; Växtekologi;

    Sammanfattning : Many vascular plant species are unable to colonise calcareous sites, the floristic composition of adjacent limestone and acid silicate soils differing markedly. The inability of these 'calcifuge' species to establish themselves and grow on limestone soil appears to mainly be related to their low capacity for solubilising and absorbing phosphate and/or iron from such soils.

  5. 4. Airway epithelial shedding: Morphological and functional aspects in vivo

    Författare :Jonas Erjefält; Luftvägsinflammation; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; eosinophils; neutrophils; plasma exudation; barrier restitution; basal cells; ciliated cells; secretory cells; Epithelial repair; epithelial shedding; fibrinogen; fibronectin; Respiratory system; Andningsorganen;

    Sammanfattning : Epithelial damage may contribute to the pathology in airway diseases such as asthma and rhinitis. However, the distribution of epithelial shedding in inflammatory airway diseases and, particularly, the ensuing repair processes are largely unknown. LÄS MER

  7. 5. Microvascular inflammatory response in the skin

    Författare :Vladimir Evilevitch; Lunds universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; medicinsk instrumentering; Physiology; Fysiologi; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; sodium nitroprusside; terbutaline; anandamide; TRPV1; skin prick test; vanilloid receptor; skin microcirculation; laser Doppler imaging; Plasma exudation; vasodilatation;

    Sammanfattning : This thesis examines the microvascular inflammatory response in the skin. The microvascular response includes vasodilatation and plasma exudation. In the first three studies, the combined response was measured in guinea pig skin with a technique based on detection of radiolabelled protein. LÄS MER
