2. 1. Molecular and structural patterns of guided bone regeneration (GBR). Experimental studies on the role of GBR membrane and bone substitute materials

   Author : Ibrahim Elgali; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Regenerative medicine; biomaterials; bone substitute; calcium phosphate; guided bone regeneration; membrane; strontium; bone defect; bone remodeling; inflammation; cytokines; chemokines; growth factors; gene expression; histomorphometry; in vivo;

   Abstract : The mechanisms of guided bone regeneration (GBR) and bone healing with calcium phosphate (CaP) bone substitutes are not fully understood. The major aim of this thesis was to determine the relationship between the bone formation in bone defects and the cellular distribution and activities in association with CaP materials and/or with GBR membrane.

4. 2. Bone Metabolism in Men

   Author : Peter Gillberg; Olof Johnell; Uppsala universitet; []
   Keywords : Medical sciences; Male osteoporosis; Bone mineral density; Growth hormone; Insulin-like growth factors; Sex hormones; Growth hormone replacement; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

   Abstract : In this thesis, the importance of the growth hormone (GH)/insulin-like growth factor (IGF) system and sex steroids for male bone metabolism has been investigated, and the effects of continuous low dose GH replacement in GH deficient (GHD) adults. In a population-based sample of men, positive correlations were found between bone mineral density (BMD) and IGF-I, IGF-II, IGF binding protein (IGFBP)-3 and the testosterone/sex hormone binding globulin (SHBG) ratio.

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

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

   Abstract : 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. READ MORE

6. 4. Long-term effects of growth hormone replacement in hypopituitary adults on body composition, bone mass and cardiovascular risk factors

   Author : Mariam Elbornsson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; growth hormone; growth hormone deficiency; growth hormone replacement; bone mineral density; body composition; muscle strength; elderly; cardiovascular risk factors; pituitary irradiation;

   Abstract : Growth hormone (GH) deficient (GHD) adults have decreased bone mass and muscle strength, impaired body composition, disturbed serum lipid pattern and increased morbidity and mortality in cardiovascular and cerebrovascular diseases. GH replacement normalizes most of these aberrations within the first year of treatment. READ MORE

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

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

   Abstract : 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. READ MORE
