  1. 11. Cardiovascular effects of growth hormone, IGF-I and growth hormone secretagogues

    Författare :Åsa Tivesten; Göteborgs universitet; []
    Nyckelord :cardiovascular system; growth hormone; insulin-like growth factor-I; growth hormone secretagogues; echocardiography.;

    Sammanfattning : Growth hormone (GH) may exert direct growth-promoting and metabolic actions on target tissues, but most of its effects are mediated by circulating (endocrine) or local (auto-/paracrine) insulin-like growth factor-I (IGF-I). The GH/IGF-I system has an important role during cardiac development and for maintaining the structure and function of the heart. LÄS MER

  3. 12. Head and Neck Cancer : Factors Affecting Tumour Growth

    Författare :Kaarina Sundelin; Elisabeth Paulette-Hultcrantz; Karin Öllinger; Karin Roberg; Hans Gustafsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Head and neck cancer; Chemoradiotherapy; Tumour; Malignant salivary; Metallothionein; Neo-angiogenesis; Metastases; Cytokine tumour necrosis factor-alpha; hepatocyte growth factor; Oncology; Onkologi;

    Sammanfattning : Head and neck cancer is the fifth most common cancer worldwide with an estimated annual global incidence of over 500 000 cases. These malignant tumours develop in the mucosal linings of the upper respiratory tract or in the salivary glands. The most common sites are in the oral cavity and larynx. LÄS MER

  4. 13. Vascular Endothelial Growth Factor (VEGF) and Peripheral Nerve Regeneration

    Författare :Mariann Sondell; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Schwann cell; SCG; rat; peripheral nerve regeneration; neuropilin-1; nerve repair; mouse; growth factor; flk-1; axonal outgrowth; DRG; VEGF; Animal physiology; Djurfysiologi;

    Sammanfattning : This thesis concerns vascular endothelial growth factor (VEGF) and its possible role as a neurotrophic factor. I have investigated the effect of VEGF on neurons in culture but also in vivo, following a crush lesion of the sciatic nerve, and following nerve repair. LÄS MER

  5. 14. Murine B lymphocyte growth regulation : a study of host defence factors and their mimicry by Mycoplasma arginini

    Författare :Erik Ruuth; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; B lymphocyte; growth; lymphokine; lymphokine-like; host-parasite; M. arginini; membrane acyl protein;

    Sammanfattning : Immune responses are the result of extended clonal growth and maturation of specific precursors preexisting in low frequencies. Clonal expansion is partly controlled by soluble factors, thus, their identification is essential for the understanding of the immune response regulation. LÄS MER

  7. 15. Hormonal regulation of liver and tumor growth

    Författare :Ville Wallenius; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Liver; cytokine; interleukin-6; tumor necrosis factor; primary liver growth promoter; cyproterone acetate; nafenopin; hepatocyte growth factor; HGF receptor; tumor; sarcoma; N-terminal; truncated;

    Sammanfattning : The aims of this thesis were to investigate the regulatory functions of interleukin-6 (IL-6) and tumor necrosis factor-a (TNF-a) on liver growth, and the importance of hepatocyte growth factor (HGF) and the HGF receptor (Met) for growth of mesenchyme-derived tumors. The studies on different types of liver growth, measured as weight, DNA and protein content, and DNA synthesis, were performed on mice lacking the IL-6 or the TNF receptor-1 gene back-crossed to the C57bl/6 strain.
