  1. 1. Mammalian sperm flagella and cilia

    University dissertation from Stockholm : Karolinska Institutet, Department of Cell and Molecular Biology

    Author : Jikui Guan; Karolinska Institutet.; Karolinska Institutet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : In mammals, both sperm flagella and cilia are axoneme-containing organelles. The sperm flagella are major parts of the spermatozoa that are male gametes produced in the testis from progenitor spermatogonia through a process called spermatogenesis. READ MORE

  2. 2. Ultrastructural Studies of the Airway Epithelium in Airway Diseases

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

  3. 3. Studies of Mucociliary Activity and Blood Flow in the Upper Airways, with Special Reference to Endothelins and Nitric Oxide

    University dissertation from Dept. of Otorhinolaryngology, Head and Neck Surgery, University Hospital of Lund, S-221 85 Lund, Sweden

    Author : Thomas Runer; Lunds universitet.; Lund University.; [1996]
    Keywords : substance P; Otorhinolaryngology; rabbit; nitric oxide; nasal mucosa; mucociliary clearance; methacholine; maxillary sinus; endothelins; human; cilia; blood flow; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen; MEDICIN; MEDICINE;

    Abstract : The aim with this thesis was to investigate effects of vasoactive mediators on mucociliary activity and blood flow in rabbit and human experimental models. Mucociliary activity in vivo and ciliary beat frequency (CBF) in vitro were measured with photoelectric techniques. Blood flow was measured with laser Doppler flowmetry. READ MORE

  4. 4. The study of sensory cilia development in Caenorhabditis elegans

    University dissertation from Stockholm : Karolinska Institutet, Biosciences and Nutrition

    Author : Evgeni Efimenko; Karolinska Institutet.; Karolinska Institutet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : p>Cilia and flagella are widespread eukaryotic subcellular components that are conserved from green algae to mammals. In different organisms they function in cell motility, movement of extracellular fluids and sensory reception. READ MORE

  5. 5. Differential expression pattern of CEACAM1 isoforms in polarized epithelial cells, it´s regulation and some functional consequences

    University dissertation from Stockholm : Karolinska Institutet, Department of Cell and Molecular Biology

    Author : Ulla Sundberg; Karolinska Institutet.; Karolinska Institutet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CEACAM1; adhesion; lateral localization; adherens junctions; desmosomes; primary cilia;

    Abstract : The cell adhesion molecule CEACAM1 is expressed in epithelia, small vessel endothelia and leukocytes as two major, co-expressed isoforms, CEACAM1-L and CEACAM1-S, which differ in their cytoplasmic domains. CEACAM1 has been found both in cell-cell contact areas and on apical surfaces of polarized epithelial cells. READ MORE
