  1. 1. Cell motility : the dynamics of the cortical weave of microfilaments and its relation to microtubules and coated vesicles in fibroblasts and glial cells

    University dissertation from Stockholm : Stockholm University

    Author : Anna-Stina Höglund; Stockholms universitet.; [1985]

    Abstract : Actin and myosin, the major components of the microfilament system are found in most - if not all - eukaryotic cells. In muscle they form the basis of the contractile apparatus which generates the rapid, strong and unidirectional movements that characterizes muscle activity. READ MORE

  2. 2. Biological significance of ECL-cell histamine

    University dissertation from Department of Pharmacology, Lund University

    Author : Kjell Andersson; [1996]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; Physiology; ultrastructure; gastric acid secretion; a-fluoromethylhistidine a-FMH ; stomach; oxyntic mucosa; histidine decarboxylase HDC ; Enterochromaffin-like ECL cell; histamine; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Abstract : In the oxyntic mucosa of the mammalian stomach, histamine is stored in enterochromaffin-like (ECL) cells and in mucosal mast cells. The activity of the histamine-forming enzyme, histidine decarboxylase (HDC), is high in ECL cells but lower in the mucosal mast cells. READ MORE

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

    University dissertation from Göteborg : University of Gothenburg

    Author : Maria Lennerås; Göteborgs universitet.; Gothenburg University.; [2016]
    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

  4. 4. The cell wall ultrastructure of wood fibres effects of the chemical pulp fibre line

    University dissertation from Stockholm : KTH

    Author : Jesper Fahlén; KTH.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; atomic force microscopy; cellulose; cell wall; drying; fiber; Kemiteknik; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Abstract : Knowledge of the ultrastructural arrangement within wood fibres is important for understanding the mechanical properties of the fibres themselves, as well as for understanding and controlling theultrastructural changes that occur during pulp processing.The object of this work was to explore the use of atomic force microscopy (AFM) in studies of the cell wall ultrastructure and to see how this structure is affected in the kraft pulp fibre line.

  5. 5. Cubic Cell Membrane Architectures. Taking another look at membrane bound cell spaces

    University dissertation from Department of Food Technology, Lund University

    Author : Tomas Landh; Lund University.; Lunds universitet.; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; projections; image analysis; periodic cubic surfaces; membrane morphology; cubic membranes; cell ultrastructure;

    Abstract : A systematic study of cell membrane morphologies whose structure is governed by cubic symmetries has been performed. It is suggested that they are described by periodic cubic surfaces for which space filling surface foliations given by truncated Fourier series defined by the space groups is used as structural representations.
