  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. Lokala organ i Norden 1968-1986 : från idé till verklighet

    Författare :Kerstin Kolam; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Central-local government relations; decentralization; geographical distribution of services and welfare; local democracy; multi-functioned committees; municipalities; neighbourhood councils; Nordic countries; sub-municipal committees;

    Sammanfattning : Neighbourhood councils are sub-municipal committees which operate within a geographically delimited area of a municipality or a municipal department. Their activities cover a single established policy area such as social services (single functioned committee) or several areas such as education, leisure, and social issues (multi-functioned committee).

  4. 3. Organ-specific mechanisms of vascular development in the mesentery

    Författare :Yang Zhang; Taija Mäkinen; Wiebke Herzog; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lymphatic vasculature; mesentery; hemogenic endothelium; lymphvasculogenesis; endothelial integrity; platelet; blood-filled lymphatic vessel; morphogenesis and maturation; compensation;

    Sammanfattning : Understanding how the vascular systems are formed has significant clinical importance. General mechanisms underlying vascular development have been extensively studied during the past decades. However, the mechanisms regulating the development and function of the blood and lymphatic vessels in specific organs are poorly understood. LÄS MER

  5. 4. Embryonic ecdysone-induced gene expression and progression of organ morphogenesis

    Författare :Tina Mitra Chavoshi Alizadeh; Göteborgs universitet; []
    Nyckelord :Drosophila; trachea; hindgut; tubulogenesis; luminal matrix; ecdysteroid; EcR:Usp; dorsal closure;

    Sammanfattning : The formation of an epithelial organ requires a set of organ-specific gene programs that instruct parallel and successive developmental events. Still, it is unclear what are the core regulatory programs and how such programs are timely coordinated within the organ. LÄS MER

  7. 5. Mucins in normal and diseased airways

    Författare :Hans Hovenberg; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Respiratory system; Submucosal glands; Goblet cells; Organ culture; Respiratory tract; Mucins; Mucus glycoproteins; Andningsorganen;

    Sammanfattning : Mucus glycoproteins (mucins) are the principal constituents of respiratory secretions in health and disease. The increased 'acidity' of mucin producing cells in the bronchitic airways is not reflected in a change of negative charge of bronchitic mucins. LÄS MER
