  2. 16. Enhancing spruce defence against an insect pest : effects of somatic embryogenesis and methyl jasmonate treatment

    Author : Kristina Berggren Nieto; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Enhancing plant resistance against pests has the potential to become a sustainable alternative within forestry. Exogenous application of the plant defence signalling hormone methyl jasmonate (MeJA) as well as propagation through somatic embryogenesis (SE) has been shown to increase Norway spruce (Picea abies) plant’s resistance to the major forest regeneration pest the pine weevil Hylobius abietis.

  4. 17. Laboratory Ventilation Systems: An Analysis of the Function and Flow Stability of Different Ductwork Design Alternatives

    Author : Madis Laaniste; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory ventilation; transient flow simulation; fume hood;

    Abstract : One of the prerequisites for high safety in laboratories for chemical and microbiological research is a well-functioning ventilation system. The most typical safety measure in these laboratories is to use a fume hood as a place for activities that can cause dangerous emissions to the room air. READ MORE

  5. 18. LXR and aromatase knock-out mice : animal models providing insight into human diseases

    Author : Hyun-Jin Kim; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : In our characterization of mouse strains carrying mutations in nuclear receptor and aromatase genes we have found phenotypes which resemble four human diseases: benign prostatic hyperplasia (BPH), Sjögren s syndrome (SS), amyotrophic lateral sclerosis (ALS), and exocrine pancreatic insufficiency. The work in this thesis was designed to understand the roles of LXRalpha, LXRbeta and aromatase in development of these diseases and to investigate whether these animal models help us (1) to understand the etiology of the corresponding human diseases and (2) to develop new therapeutic approaches for the treatment of these diseases.

  6. 19. Biliary strictures in primary sclerosing cholangitis : aspects on inflammation and malignancy

    Author : Erik von Seth; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Primary sclerosing cholangitis (PSC) is a rare liver disease that is characterized by chronic inflammation of bile ducts with development of fibrosis and strictures. The pathogenic mechanisms involved in this disease are insufficiently understood. READ MORE

  7. 20. SODIUM/IODIDE SYMPORTER-NIS Abundant and Important in Gastric Mucosa

    Author : Malin Josefsson; Neurogastroenterologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ussing chamber; MNNG; gastric iodide secretion; ouabain; gastric cancer; sodium perchlorate; gastric NIS; bile duct cancer; Sodium iodide symporter;

    Abstract : ABSTRACT Background: Iodine is essential for development and growth as a constituent in thyroid hormones. Biological mechanisms for iodide uptake and concentration are very important, espe-cially as iodine is a relatively scarce element. READ MORE
