  1. 1. Plant pathogen defense: Signalling, resistance and cell death

    Author : Oskar N. Johansson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Pseudomonas; cell death; pathogens; plant defense; hypersensitive response; glycolipid; reactive oxygen species; blumeria graminis; erysiphe pisi;

    Abstract : Pathogenic microorganisms are present everywhere in nature and infect both animals and plants. Phytopathogenic microorganisms cause diseases on plants, and are responsible for crop loss amounting in the order billions of dollars annually. READ MORE

  2. 2. Electrochemical and Enzymatic In Vitro Studies on Reactive Drug Metabolites. Synthesis, Characterization and Avoidance

    Author : Tove Johansson Mali´n; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Cytochrome P450; Drug; Electrochemical oxidation; Electrochemistry; Intermediate; Metabolism; Metabolic activation; Mimicry; Reactive Metabolite; Trapping.;

    Abstract : During development of pharmaceuticals, it is essential to as early as possible identify and preferably avoid formation of reactive metabolites and intermediates. Reactive metabolites may represent obstacles in the development and use of drugs, due to their potential toxicity. READ MORE

  3. 3. Essays on Measurement Error and Nonresponse

    Author : Fredrik Johansson; Anders Klevmarken; Per Johansson; Markus Jäntti; Uppsala universitet; []
    Keywords : Economics; Nationalekonomi;

    Abstract : Essay 1 deals with measurement errors. Matching survey data with administrative records provides unique opportunities to evaluate the statistical properties of respondents' answers. This paper focuses primarily on home ownership and wealth variables. READ MORE

  4. 4. Cellular and molecular responses of periodontal connective tissue cells to Actinobacillus actinomycetemcomitans cytolethal distending toxin

    Author : Georgios N. Belibasakis; Sotirios Kalfas; Ulf H. Lerner; Anders Johansson; Veli-Jukka Uitto; Umeå universitet; []
    Keywords : Medical sciences; Actinobacillus actinomycetemcomitans; cytolethal distending toxin; periodontal connective tissue cells; localized aggressive periodontitis; growth arrest; bone resorption; receptor activator of NF-κB ligand; osteoprotegerin; pro-inflammatory cytokines; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; odontologi; Odontology;

    Abstract : Actinobacillus actinomycetemcomitans is present in elevated proportions and numbers in dental bacterial biofilms of patients with localized aggressive periodontitis. This variant of periodontal disease, occurring in adolescents and young adults, is characterized by rapid and severe destruction of the connective tissues and bone supporting the teeth, eventually culminating in tooth loss.
