  2. 16. Mapping ultrastructural effects of proteotoxic stress on S. cerevisiae

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

    Abstract : 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. READ MORE

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

    Author : Maria Lennerås; Göteborgs universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 20. Mechanisms of Osseointegration: Experimental Studies on Early Cellular and Molecular Events in vivo

    Author : Omar Omar; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osseointegration; titanium; bone; gene expression; bone-implant interface; qPCR; inflammation; cytokine; chemotaxis; chemokine; integrin; bone formation; remodeling; in vivo; rat; immunohistochemistry; ultrastructure; biomechanical torque test;

    Abstract : The early cellular and molecular activities determining the early tissue response and bone formation at bone/implant interface are not fully understood. The general aim of the current thesis was to develop a model for studying the early molecular and cellular activities in different bone types, and in response to different implant surface properties.
