    Sammanfattning : Approximately 7000 women are diagnosed and 1500 women die from breast cancer in Sweden every year. The aim of this thesis was to study the interplay of polymorphisms, hormone levels, lifestyle, and the use of concomitant medication in relation to risk and prognosis in two cohorts: one composed of young healthy women from high-risk breast cancer families and the other of breast cancer patients from the general population.

    Sammanfattning : The gastrointestinal tract has two opposing functions; to effectively absorb nutrients and to act as a safety barrier against hazardous substances in the environment. After birth these functions develops gradually. LÄS MER

  4. 8. Selenoproteins in the Bovine Mammary Gland. Regulation of mRNA and Protein Expression

    Författare :Katharina Bruzelius; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Livsmedelsteknik; Food and drink technology; metabolism; Biokemi; Metabolism; Biochemistry; Naturvetenskap; milk; Natural science; cancer; prolactin; insulin; hydrocortisone; retinoic acid; MAC-T; northern blot; two-dimensional electrophoresis; bovine mammary gland; selenium; selenoprotein;

    Sammanfattning : Selenium is a micronutrient that is essential for many important life processes due to the action of the specific selenoproteins containing one or more of the 21st amino acid, selenocysteine. Twenty-five selenoprotein genes have been found in the human genome but the function of many of them is not yet known. LÄS MER

  5. 9. Effects of palatable diets on appetite regulation, appetite peptides and neurogenesis

    Författare :Andreas Lindqvist; Aptitkontroll; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sekretion; Endokrinologi; diabetologi; Appetite regulation; Ghrelin; Obesity; Leptin; Endocrinology; diabetology; secreting systems;

    Sammanfattning : Obesity is increasing throughout the world at an epidemic rate, partly due to increased consumption of diets rich in fat and/or sugar. Ghrelin and leptin are hormones, originating from the periphery, involved in the regulation of food intake and of maintaining energy homeostasis. LÄS MER

  7. 10. GABA in the islets of Langerhans

    Författare :Anna Wendt; Diabetes - öcellsexocytos; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; secreting systems; diabetologi; sekretion; Endokrinologi; Endocrinology; SLMV; paracrine regulation; LDCV; islets of Langerhans; autocrine regulation; GABA; diabetology;

    Sammanfattning : GABA (γ-aminobutyric acid) is a well-known inhibitory neurotransmitter in the CNS. GABA is also present at high concentrations in the insulin-producing β-cells in the islets of Langerhans, but its function there is less clear. GABA is believed to accumulate in SLMVs (synaptic-like microvesicles). LÄS MER
