1. Endogenous sex hormones and cardiometabolic risk factors – population-based studies within the Skaraborg Project
Sammanfattning : Cardiovascular diseases are the major contributors to mortality in Sweden and globally. Men have a higher incidence of cardiovascular diseases compared to women, until women reach the menopause. Levels of sex hormones might explain these sex differences beyond known differences in risk factors. LÄS MER
2. Bone Metabolism in Men
Sammanfattning : 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.

3. Endogenous hormones in the etiology of ovarian and endometrial cancers
Sammanfattning : The main purpose of this thesis was to examine the relationship of pre-diagnostic circulating levels of sex-steroids (androgens and estrogens), sex hormone binding globuline (SHBG), insulin-like growth factor-I (IGF-I), IGF binding proteins (BP) and C-peptide (as a marker of pancreatic insulin secretion) with risk of ovarian and endometrial cancer. Additionally, the interrelationships of body mass index (BMI), sex-steroids, IGF-I and IGFBP-3 were examined. LÄS MER
4. The EGF-like Modules of Anticoagulant Protein S. Studies of Ca2+ binding and module interactions
Sammanfattning : Protein S functions as a cofactor to activated protein C (APC) in the degradation of factors Va and VIIIa. In plasma protein S circulates in two forms; 30-40 % circulates as free protein S molecules while the remaining 60-70 % exists in a 1:1 complex with C4b-binding protein (C4BP). Only the free form of protein S functions as a cofactor to APC. LÄS MER
5. Hormone concentrations during pregnancy and maternal risk of epithelial ovarian cancer
Sammanfattning : Background: The aim of this thesis was to study the relationship of pre-diagnostic circulating concentrations of sex steroid hormones (androgens, estradiol, 17-hydroxyprogesterone, and progesterone), growth factors (insulin-like growth factor-I (IGF-I), placental growth hormone (GH)), sex hormone binding globulin (SHBG), and anti-Müllerian hormone (AMH) with risk of epithelial ovarian cancer (EOC) overall, and by tumor invasiveness and histology. A longitudinal study was used to assess patterns of hormonal changes during a single pregnancy, and in two consecutive pregnancies. LÄS MER
