  2. 16. Ion transport in exocrine glands with reference to cystic fibrosis

    Author : Ailing Zhang; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; ion transport; cystic fibrosis; submandibular gland; airway submucosal gland; X-ray microanalysis; cytosolic Ca2 concentration; immunocytochemistry; Cellbiologi; Cell biology; Cellbiologi; Human Anatomy; anatomi;

    Abstract : Aspects of ion transport in rat submandibular gland acinar cells at the subcellular level, and the regulation of chloride secretion and calcium mobilization in cultured pig tracheal gland acinar cells were studied with reference to the disease cystic fibrosis.In adult rat submandibular gland acinar cells, both cholinergic and α-adrenergic stimulation induced efflux of K+ and of C1-, but the response was generally less with α-adrenergic stimulation.

  4. 17. Lung volumes and lung mechanics in anesthetized children

    Author : Adalbjörn Thorsteinsson; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sulfur hexafluoride; Anaesthesiology; lung volumes; lung compliance; Anesthesia: pediatric; functional residual capacity; intensive care; Anestesiologi; ventilation inhomogeneity; intensivvård; airway closure;

    Abstract : The thesis was intended to fill gaps in the knowledge regarding the normal development of lung volumes and lung mechanics in children, from young infancy to the mid-teens. In particular, data were previously lacking regarding pre-school children. The studies were done during anesthesia and muscle relaxation. READ MORE

  5. 18. Molecular regulation of epithelial tube size

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

    Abstract : 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. READ MORE

  6. 19. Regulation of epithelial morphogenesis in Drosophila by the Emp scavenger receptor

    Author : Ana Sofia Pinheiro; Christos Samakovlis; Sofia Araújo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Emp; scavenger receptor; CD36; cytoskeleton; Src kinase; Diap; DrICE; Hipo Yki; endocytosis; Drosophila; airways; molekylär biovetenskap; Molecular Bioscience;

    Abstract : The respiratory system of Drosophila melanogaster, the trachea, is widely used as a model system to study the development of branched tubular organs. Airway maturation in Drosophila entails a series of sequential events: first, a massive apical secretion of luminal proteins initiates diametric tube expansion, second an endocytic wave removes luminal proteins and finally liquid clearance and gas filling converts the nascent epithelial tubes to a functional respiratory organ.

  7. 20. The rhomboid family of intramembrane proteases, conserved regulators of cell communication

    Author : Marco Gallio; Per Kylsten; Pernille Rørth; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell communication; proteolysis; EGF receptor; development; genetics;

    Abstract : The development of multicellular organisms relies heavily on cell communication. Cells send and receive complex sets of signals, harmonising their growth and differentiation with that of other, often distant, cell populations. In animals, the Epidermal Growth Factor Receptor (EGFR) is an important mediator of cell communication. READ MORE
