  1. 1. Understanding and manipulating primary cell walls in plant cell suspension cultures

    Författare :Felicia Leijon; Vincent Bulone; Katja Salomon Johansen; KTH; []
    Nyckelord :Callose synthase; carbohydrate-binding module; cell wall engineering; cellulose microfibril; cellulose nanocrystal; glycosyltransferase; mass spectrometry; plasmodesmata; Populus; primary cell wall; radiometric assay; spectrophotometric assay; Biotechnology; Bioteknologi;

    Sammanfattning : The cell wall is required for many aspects of plant function and development. It is also an accessible and renewable resource utilized both in unrefined forms and as raw material for further development. Increased knowledge regarding cell wall structure and components will contribute to better utilization of plants and the resources they provide. LÄS MER

  3. 2. Development and Applications of some Radioanalytical Procedures: Analysis of β- and α-Emitting Radionuclides Using Radiometric and ICP-MS Detection Methods

    Författare :Henrik Ramebäck; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion; plutonium; 90Sr; curium; uranium; 99Tc; bentonite clay; analysis; UO2 fuel; leaching; americium; neptunium;

    Sammanfattning : Analyses of radionuclides are important in environmental monitoring and in research. However, as in the analysis of many other species, interferences may be a problem. In a-spectrometric detection, 238Pu interferes with 241Am, owing to their similar decay energies. LÄS MER

  4. 3. Hyaluronan in malignant pleural mesothelioma with special reference to diagnosis, tumourbiology and prognosis

    Författare :Anders Thylén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Malignant pleural mesothelioma; hyaluronan; prognosis; methods; immunohistochemistry; tumourvolume; chemotherapy; tirapazamine; cisplatin;

    Sammanfattning : Malignant pleural mesothelioma (MPM), the primary malignant tumour of the pleural cavity, is an uncommon and treatment resistant tumour. The prognosis is poor. In many, but not all cases the concentration of hyaluronan (Hya) is increased in pleural effusion. The clinical relevance of Hya in MPM is not clear. LÄS MER

  5. 4. Microsomal epoxide hydrolase : characterization, induction, and in vitro modulation, of the catalytic activity

    Författare :Janeric Seidegård; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Microsomal epoxide hydrolase has been characterized, mainly in the fiver and lung of the rat.A reported radiometric assay using 3H-styrene 7,8-oxide as substrate has been modified by purifying the substrate before use, decreasing the incubation volume, and prolonging the incubation time.

  7. 5. Cell wall biosynthesis in the pathogenic oomycete Saprolegnia parasitica

    Författare :Elzbieta Rzeszutek; Vincent Bulone; Carol Munro; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cellulose biosynthesis; chitin biosynthesis; cellulose synthase genes; chitin synthase genes; oomycetes; Saprolegnia parasitica; Biotechnology; Bioteknologi;

    Sammanfattning : The oomycete Saprolegnia parasitica is a fungus-like microorganism responsible for the fish disease saprolegniosis, which leads to important economic losses in aquaculture. Currently, there is no efficient method to control the infection and therefore methods for disease management are urgently needed. LÄS MER
