  1. 6. 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

  2. 7. Growth and Behaviour : Epigenetic and Genetic Factors Involved in Hybrid Dysgenesis

    Författare :Wei Shi; Reinald Fundele; Diethard Tautz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Interspecies hybridization; hybrid dysgenesis effect; speciation; genomic imprinting; epigenetics; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : In mammals, the most frequently observed hybrid dysgenesis effects are growth disturbances and male sterility. Profound defects in placental development have been described and our work on hybrids in genus Mus has demonstrated putative hybrid dysgenesis effects that lead to defects in lipid homeostasis and maternal behavior.

  3. 8. Identification of novel growth hormone-regulated factors

    Författare :Björn Andersson; Göteborgs universitet; []
    Nyckelord :Growth hormone; idiopathic short stature; growth hormone deficient; prepubertal; children; genomic; proteomic;

    Sammanfattning : The studies described in this thesis aimed to identify novel factors involved in the regulation of longitudinal growth and bone mineralization in response to growth hormone (GH) treatment. This was done by performing a single factor study (Paper I) where it was found that growth response was negatively correlated with adiponectin levels during the first year of GH treatment in short prepubertal children.

  4. 9. Liver regeneration : With reference to malnutrition and growth factors

    Författare :Stefan Skullman; Linköpings universitet; []
    Nyckelord :cholecystokinin; energy substrates; epidermal growth factor; insulin-like growth factor I; liver composition; liver regeneration; malnutrition; pancreaticobiliary diversion; protein synthesis; rat; transfonning growth factor alpha; MEDICINE; MEDICIN;

    Sammanfattning : The liver has a unique capacity to regenerate after damage, irrespective of cause. The regulatory mechanisms of this regeneration are not fully known. Liver regeneration· is associated with rapid growth and thereby increased demands for energy and synthesis of new compounds. LÄS MER

  5. 10. On growth factors and titanium implant integration in bone

    Författare :Victoria Franke Stenport; Göteborgs universitet; []
    Nyckelord :growth factors; signal peptides; titanium implants; osseointegration; in vivo studies;

    Sammanfattning : PurposeThe purpose of the present thesis was to investigate the bone tissue response around titanium implants with one growth factor stimulating hormone and a few different growth factor substances.Material and methodsIn four studies (study I to IV) a rabbit model were used and the growth factors i.e. LÄS MER
