  1. 1. Molecular regulation of epithelial tube size

    Författare :Erika Tång Hallbäck; Göteborgs universitet; []
    Nyckelord :Drosophila; tube shape; trachea; chitin; luminal matrix; epithelial tubes; morphogenesis; chloride channel; subapical actin;

    Sammanfattning : In nature, epithelial tubes are vital structures in organ design and are required for transport of gases and liquids in organs, such as the vascular system, the vertebrate lung and the kidneys. The tubular epithelium is single layered, but is often reinforced by layers of muscular support. LÄS MER

  3. 2. Genetic and molecular regulation of epithelial tube morphogenesis

    Författare :Anna Tonning; Göteborgs universitet; []
    Nyckelord :epithelial tube morphogenesis; trachea; Drosophila; chitin; chitin synthase; apical extracellular matrix; paracellular diffusion barrier; tube expansion; septate junctions;

    Sammanfattning : Networks of epithelial tubes, such as the vertebrate lung, kidney and vascular system, enable transport of gases and nutrients to all tissues in the body. These tubes are built up by a single layer of polarized epithelial cells, with the apical membrane facing the lumen. LÄS MER

  4. 3. Evaluation of Respiratory Mechanics by Flow Signal Analysis : With Emphasis on Detecting Partial Endotracheal Tube Obstruction During Mechanical Ventilation

    Författare :Rafael Kawati; Michael Lichtwarck-Aschoff; Ulf Sjöstrand; Anders Larsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; Complication: obstructed endotracheal tube; Equipment:endotracheal tube; Heart: cardiogenic oscillation; Respiratory mechanics: respiratory mechanics; Ventilation: controlled mechanical; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård;

    Sammanfattning : Evaluating respiratory mechanics during dynamic conditions without interrupting ongoing ventilation and flow, adds to the information obtained from the mechanics derived from static (= no flow) conditions, i.e., the flow signal has the potential to provide information on the properties of the respiratory system (including the tubing system).

  5. 4. Mucin-like proteins in Drosophila development

    Författare :Zulfeqhar Ali Syed; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mucins; PTS-domains; Drosophila development; Tube shape; Hindgut; Midgut; Malpighian tubules; Luminal matrix;

    Sammanfattning : Mucins are large and highly glycosylated proteins and major component of the mucus that coats the lining of epithelial organs. Mucins are characterized by the presence of extended regions rich in the amino acids Proline, Threonine and Serine (PTS domain), where the Serines and Threonines are O-glycosylated to form sugar-rich mucin domains.
