  1. 21. Insights into the Molecular Mechanisms of Litter Decomposition and Assimilation of Nitrogen by Ectomycorrhizal Fungi

    Författare :Firoz Shah; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ectomycorrhizal fungi; Paxillus involutus; organic matter degradation; Fenton chemistry; carbon availability; N assimilation; C and N cycling; protein degradation pathway; secondary metabolites;

    Sammanfattning : Ectomycorrhizae is the dominant type of mycorrhiza found in association with tree roots in boreal and northern temperate forests. In this symbiosis, the fungal partner derives energy from photosynthates provided by the host trees and in return delivers soil-derived nutrients such as nitrogen (N). LÄS MER

  3. 22. On the mind's time : production, perception, and pianists performance of rhythms : neural correlates and neuroanatomical changes

    Författare :Sara L Bengtsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Human movements are impressively flexible and precise. They are also coloured by the characteristics with which each person performs an act. This is evident in everyday activities, in sports, in art, and in music performance. LÄS MER

  4. 23. Lithium and brain plasticity - studies on glial cell changes and electroconvulsive treatment-induced amnesia in rats

    Författare :Babak Hooshmand; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Alzheimer’s disease;

    Sammanfattning : The overall aim of this thesis was to investigate the relation of homocysteine (tHcy), vitamin B12, and folate with Alzheimer’s disease (AD), cognitive performance, and structural brain changes in population-based studies of Finnish and Swedish elderly individuals. Study I. LÄS MER

  7. 25. Radiological and Clinical Changes in Idiopathic Normal Pressure Hydrocephalus: MRI, Vascular factors and Clinical Symptoms as Markers of Pathophysiology and Prognosis
