  2. 1. Early growth, retinopathy of prematurity and insulin-like growth factors in preterm infants

    Author : Eva Engström; Göteborgs universitet; []
    Keywords : Preterm; ROP; nutrition; growth; growth restriction; IGF-I; IGF-II; IGFBP-3;

    Abstract : Aims:Paper I: To perform measurements of the lower leg length (LLL) in preterm infants, compare and evaluate handling error and precision of two instruments, and estimate the time required to show growth.Paper II-IV: To investigate whether low postnatal levels of serum IGF-I are associated with abnormal retinal vessel development.

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

    Author : Stefan Skullman; Linköpings universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Proteolysis of insulin-like growth factor-binding protein-1, -2 and -4 : function of fragments

    Author : Katrin Brandt; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Insulin-like growth factor;

    Abstract : The insulin-like growth factors (IGF-I and IGF-II) stimulate cell growth, survival and differentiation, and have insulin-like activity. A family of six IGF-binding proteins (IGFBP-1 through -6) bind to IGFs with high affinity and modulate their activity in the circulation and locally at cell-surface receptors. READ MORE

  6. 4. Growth factors in spermatogenesis

    Author : Aida Wahlgren; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Testis; seminiferous tubules; proliferation; growth factors; sex steroids;

    Abstract : The aim of this study was to increase the knowledge of die effects of locally produced growth factors and hormones on germ cell proliferation in rat testis in vitro. Since impaired sperm production and function accounts for half the cases of infertility, it is important to understand the physiological actions in germ cell development. READ MORE

  7. 5. Regulation of insulin-like growth factor-II in human liver

    Author : Henrik von Horn; Karolinska Institutet; Karolinska Institutet; []
    Keywords : IG17-II; IGF2; IGFBPs; liver; hepatoblastoma; GH; hypoxia;

    Abstract : Insulin-like growth factors-I and -II (IGF-I and -II) are mitogens in a number of cell types and also have insulin-like actions. IGF-II has an autocrine role in a variety of malignancies; and hypoglycemia is well documented in conditions associated with elevated IGF-II precursor forms in the circulation. READ MORE
