  1. 11. The influence of sex hormones on neuromuscular function and premenstrual symptoms

    Författare :Linda Ekenros; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :postural control;

    Sammanfattning : The menstrual cycle with fluctuation in female sex hormones has been suggested to influence neuromuscular function. However, variation in ligament laxity, soft tissue stiffness, and skeletal muscle strength across the menstrual cycle has led to conflicting results. LÄS MER

    Sammanfattning : This thesis concerns the effects of low-dose oral contraceptives (OCs) on endogenous hormones, insulin-like growth-factor-1 (IGF-1), sexual hormone binding globulin (SHBG), and body constitution in two groups of healthy women aged 19­25 who had never been pregnant. Prolactin concentrations were elevated in a subgroup of present and former users. LÄS MER

  4. 13. Chemical Transformation of Inorganic Species in Thermochemical Conversion of Waste-Derived Fuels - The Role of Oxygen Carriers

    Författare :Ivana Stanicic; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxygen carriers; Waste-derived fuels; thermodynamic equilibrium calculations; heavy metals; chemical looping;

    Sammanfattning : Waste-derived fuels are used increasingly in heat and power production systems in Sweden. Thermal conversion of waste-derived and biomass fuels offers the possibility of achieving carbon dioxide-neutral or even negative emissions. To limit global warming, it is essential to integrate these systems with carbon capture and storage. LÄS MER

  5. 14. Growth Hormone and Gender. Studies in Healthy Adults and in Patients with Growth Hormone Disorders

    Författare :Britt Edén Engström; Uppsala universitet; []
    Nyckelord :Medical sciences; Growth hormone; gender; ambulation; oral contraceptives; epinephrine; GH treatment; age; E2-implant; IGF-I; octreotide; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : The use of a new, more sensitive immunoassay for growth hormone (GH) revealed that the serum levels in men were lower than expected in sera drawn ambulatory in the morning after an overnight fast and that the gender difference was more than 10 times greater than reported. These observations led to a more thorough study on the impact of gender and sex steroids on the levels of GH and other hormones in ambulatory morning samples and over a 24-hour period. LÄS MER

  7. 15. Studies on organochlorine environmental contaminants with emphasis on analytical methods and occurrence in humans

    Författare :Cecilia Weistrand; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Methods for multicomponent analysis of lipophilic organochlorine contaminants(OCs) in blood plasma and lipid-rich tissues are presented. By using the described methods, polychlorinated biphenyls (PCB), polychlorinated naphthalenes (PCN), hexachlorobenzene(HCB), 1,1-dichloro-2,2-bis(4 chlorophenyl)ethene (p,p'-DDE) and methylsulphonyl metabolites of PCB (MeSO2-PCB) and p,p'-DDE (Meso2-DDE) were determined in human blood plasma, adipose tissue and liver.
