  1. 1. Genetic dissection of tubulogenesis in the Drosophila trachea

    Författare :Johanna Hemphälä; Christos Samakovlis; Reinhard Schuh; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Drosophila; trachea; transposon mutagenesis screen; fusion; Dpp; Delta; tubular dimensions; Grainyhead; Krotzkopf verkehrt; intralumenal matrix; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : The formation of branched tubular organs, such as the mammalian lung kidney and vascular system, is an essential process in animal development. The Drosophila tracheal (respiratory) system provides a genetic model system to study the highly ordered process of branch outgrowth and fusion required to form continuous tubular networks. LÄS MER

  2. 2. Engineering the shape of bacterial cellulose and its use as blood vessel replacement

    Författare :Henrik Bäckdahl; Chalmers University of Technology; []
    Nyckelord :tissue engineering.; smooth muscle cells; bacterial cellulose; scaffold design; tubular fermentation; biocompatibility evaluation; Blood vessel; vascular graft;

    Sammanfattning : Tissue loss and organ failure are major health problems that impose great costs on society. Cardiovascular diseases are responsible for 36% of mortalities and the disease burden among adults over the age of 60. The single largest cardiovascular disease is atherosclerosis in the coronary artery. LÄS MER

  3. 3. Applications of Microwave Heating of Foods

    Författare :Birgitta Wäppling-Raaholt; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; modelling of microwave heating; microwave-assisted HTST processing; product quality.; heat transfer; microwave heating; microwave oven; heating uniformity; microwave cavity; tubular microwave in-flow processing;

    Sammanfattning : AbstractMicrowave heating of foods offers rapid and flexible heating both for consumer and industrial applications, with several advantages, such as reduced processing time (due to volumetric heating and reduced coming-up times (heating time required to reach the desired target temperature), selective heating, increased process flexibility and efficient heating (volumetric heating of the food does not require heating of a surrounding medium or package). However, successful installations requireknowledge in process design. LÄS MER

  4. 4. Genetic and molecular regulation of epithelial tube morphogenesis

    Författare :Anna Tonning; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    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

  5. 5. Long bone growth and evolution revealed by three-dimensional imaging

    Författare :Jordi Estefa; Sophie Sanchez; Per Ahlberg; Holly Woodward; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; 3D histology; hematopoiesis; humerus; tetrapods; Biologi; Biology;

    Sammanfattning : Propagation phase-contrast synchrotron radiation microtomography is a non-destructive method used for studying histology in three dimensions (3D). Using it, the 3D organization of the diaphyseal cortical vascularization in the humerus of two seymouriamorphs was analyzed in this thesis. LÄS MER
