  4. 3. On enchytraeids and naidids: Life history traits and responses to environmental stress

    Författare :Anna-Karin Augustsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; oligochaeta; terrestrial naididae; toxicity testing; asexual reproduction; sexual reproduction; drought; environmental stress; metal pollution; Ekologi; Animal ecology; Djurekologi;

    Sammanfattning : My thesis shows that enchytraeids and naidids are sensitive to various forms of environmental stress, which in combination with the wide distribution of both families make them highly suitable for use in risk assessment and soil monitoring. Enchytraeids were subject to chemical stress under both laboratory and field conditions. LÄS MER

  5. 4. Fungal Lectins. Molecular structure and function of a member of a novel lectin family

    Författare :Stefan Rosén; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; possible functions; expression; localization; binding specificities; primary and secondary structure; Agaricus bisporus; Arthrobotrys oligospora; Fungi; novel lectin family; Biology; Biologi;

    Sammanfattning : Lectins defined as non-enzyme, non-immunoglobulin carbohydrate binding proteins, have been found in a wide variety of viruses, bacteria, fungi, plants and animals. Although lectins have been purified from more than 60 different species of fungi, the structure and biological functions of these proteins are not well known. LÄS MER

  7. 5. Cyclic nucleotide signalling systems in vascular smooth muscle cells and immune system cells with special reference to phosphodiesterases PDE3 and PDE4

    Författare :Dag Ekholm; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HTLV-I; multiple sclerosis; proliferation; phosphorylation; T-lymphocytes; vascular smooth muscle; cloning; protein kinase A; cGMP; cAMP; PDE4; Phosphodiesterase; PDE3; cilostamide; rolipram; Histology; cytochemistry; histochemistry; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur;

    Sammanfattning : The cyclic nucleotide signalling systems are important in vascular smooth muscle and in the immune system, and are of interest from a pharmacological point of view. Drugs which interfere with the cyclic nucleotide levels have profound effects on heart, blood vessels and airways and have actual or potential use in several important diseases, such as heart failure, hypertension, arteriosclerosis, asthma and autoimmune diseases.
