  1. 6. Transport of sodium and protons in the human placenta. Mechanisms in normal pregnancy and alterations in intrauterine growth restriction

    Författare :Martin Johansson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; placenta; Na K ATPase; Na H exchanger; H K ATPase; intrauterine growth restriction; BeWo cells; epithelial transport;

    Sammanfattning : The syncytiotrophoblast cell of the human placenta represents the interface between maternal and fetal blood supplies. This polarized epithelium consists of a maternal facing microvillous membrane (MVM) opposing a fetal facing basal membrane (BM). This unique syncytial cell is responsible for transfer of all nutrients to the developing fetus. LÄS MER

  2. 7. Odontoblast phosphate and calcium transport in dentinogenesis

    Författare :Patrik Lundquist; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : It has been suggested that odontoblasts are instrumental in translocating Ca2+ and inorganic phosphate (Pi) ions during the mineralization of dentin. The aim of this thesis was, therefore, to study the expression of components of the transcellular ion transport system, Na+/Ca2+ exchangers and Na+-Pi cotransporters, in odontoblastic and osteoblastic cells.

  3. 8. Ion Transport in Glial and Neuroblastoma Cells

    Författare :Sonya K. A. Juthberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The aim of this thesis has been to increase our understanding of the ion channel function and the ion transport mechanisms in glial cells. The analysis has also covered Na channel function in human neuroblastoma cells in order to get a basis for similar studies of glial cells In paper I isotopes 42K and 201 Tl were used to compare the K+ transport properties in cell lines from human malignant gliomas (U-251MG and Tp-378MG), carcinomas, and brain metastasis.

  4. 9. Regulation of glucose transport and insulin-stimulated GLUT4 translocation in skeletal muscle

    Författare :Jorge E Rincón Viatela; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :skeletal muscle; glucose transport; insulin resistance; hyperglycaemia; steroid hormones; smoking; nicotine;

    Sammanfattning : Skeletal muscle represents about 40% of body mass and accounts for at least 80% of glucose disposal under insulin-stimulated conditions. Furthermore, GLUT4 transport protein is the primary component of the glucose transport system in skeletal muscle. LÄS MER

  5. 10. Advances in Pharmacological Treatment of Cystic Fibrosis

    Författare :Igor Oliynyk; Godfried M. Roomans; Marie Johannesson; Hugo R. de Jonge; Örebro universitet; []
    Nyckelord :Cystic fibrosis; CFTR; chloride transport; N-acetylcysteine; NO-donors; duramycin; intracellular calcium; azithromycin; MEDICINE; MEDICIN; Medicin; Medicine;

    Sammanfattning : Cystic fibrosis (CF) is an inborn, hereditary disease, due to mutations in the gene for a cAMP-activated chloride (Cl-) channel, the cystic fibrosis transmembrane conductance regulator (CFTR). As a result of impaired ion and water transport,the airway mucus is abnormally viscous, which leads to bacterial colonization. LÄS MER
