  1. 16. Salivary gland neoplasms : studies on the cytoskeleton, the secretory apparatus and the nuclear DNA content

    Författare :Hans Gustafsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salivary gland neoplasms; intermediate filaments; immuno- histochemistry; ultrastructure; DNA; development; histogenesis; progno¬sis;

    Sammanfattning : The heterogeneity of salivary gland neoplasms have made classification and prognostication of these tumours sometimes difficult, and the in­troduction of techniques, such as enzyme and carbohydrate histochemis­try and electron microscopy have only to a certain extent increased our knowledge in these respects. In the present study immunohistochemical methods have been used to identify intermediate filament proteins (IFP) in normal fetal and adult parotid glands, as well as in salivary neo­plasms. LÄS MER

  3. 17. Mapping ultrastructural effects of proteotoxic stress on S. cerevisiae

    Författare :Katharina Keuenhof; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; yeast; heat shock; stress; electron microscopy; ultrastructure; nuclear envelope budding;

    Sammanfattning : Cells are the basic building blocks of any living being, whether the organism consists of only one, or many cells. The different cellular components interact with one another to maintain the viability of the cell. An essential element of cells are proteins – peptide chains folded into a specific conformation unique to every protein. LÄS MER

  4. 18. A methodological platform to study molecular biocompatibility of biomaterials. Experimental and clinical studies

    Författare :Maria Lennerås; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osseointegration; titanium; inflammation; cell recruitment; cell adhesion; bone regeneration; bone remodelling; gene expression; immunohistochemistry; histomorphometry; removal torque; ultrastructure; FACS; protein profiling; transfemoral amputation; abutment; percutaneous; bacteria; clinical signs;

    Sammanfattning : The aim of this project was to develop a methodological platform in order to advance our scientific understanding of the mechanisms of osseointegration. Screw-shaped, titanium implants, with different surface properties, were inserted in the rat tibia, or incubated in mono- or co-culture of human monocytes and MSCs. LÄS MER

  7. 20. Buellia species with pluriseptate spores and the Physciaceae (Lecanorales, Ascomycotina) : Taxonomic, phylogenetic and ultrastructural studies

    Författare :Anders Nordin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Buellia; Diplotomma; phylogenetic analysis; pluriseptate spores; Physciaceae; taxonomy; ultrastructure; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; systematisk botanik; Systematic Botany;

    Sammanfattning : This dissertation is primarily focused on the Buellia species with pluriseptate spores, often referred to the section or genus Diplotomma, and secondarily on the Physciaceae. An ultrastructural study at family level gives new information on spore characters. LÄS MER
