  1. 1. Sex and violence in lobsters - a smelly business

    Författare :Malin Skog; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dominance; urine signals; recognition; Aggressive behaviours; intermoult mating; sexual dimorphism; European lobster; chemical communication; Homarus gammarus; aesthetasc morphology;

    Sammanfattning : The aim of this thesis was to study the chemical communication involved in aggressive and reproductive behaviours in the European lobster (Homarus gammarus). Both male and female H. gammarus established and maintained dominance, but the sexes used different strategies for dominance maintenance. LÄS MER

  3. 2. Chemical communication in mating shore crabs Carcinus maenas

    Författare :Mattias Ekerholm; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zoology; Urine communication; Behavior; Spatial scale; Male pheromone; Primer pheromone; Zoologi; Olfaction;

    Sammanfattning : Locating and evaluating a suitable partner for mating is one of the most important events in any sexually reproducing organism. To achieve this, an animal must be able to locate its partner over both long and short distances, and finally evoke the proper mating behaviour. LÄS MER

  4. 3. Structural studies of aquporins in human kidney and plant

    Författare :Anna Frick; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; structural biochemistry; membrane protein; aquaporin;

    Sammanfattning : Membrane proteins are key players in our biology and are links between the inside and the outside of the cell, allowing for signal transduction and transport of molecules. Aquaporins are membrane protein channels that allow water to pass in and out of the cell. Since all life depend on water, their function is vital for any type of organism. LÄS MER

  5. 4. Capillary electroseparations with mass spectrometric detection Nanoparticle-based continuous full filling and applications for complex sample matrices

    Författare :Peter Viberg; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; phthalates; continuous full filling; heterocyclic aromatic amines; pseudostationary phase; capillary electrophoresis; electrokinetic chromatography; capillary electrochromatography; nanoelectrospray; mass spectrometry;

    Sammanfattning : One of the major challenges in analytical chemistry is to find techniques and methods for determinations of low abundance compounds in complex sample matrices. This thesis describes the development of new miniaturised analytical techniques comprising capillary electroseparation combined with mass spectrometric detection. LÄS MER

  7. 5. Surviving cystectomy due to urinary bladder cancer with maintained quality of life

    Författare :Helena Thulin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In 2008 1694 men and 626 women in Sweden were diagnosed as having bladder cancer. The character of bladder cancer is highly variable ranging from moderately serious development of superficial tumors to much more serious and life threatening tumors that can infiltrate the muscle layers in the bladder (advanced bladder cancer).
