  1. 1. SNAP-25 and Cdk5 as exocytotic regulators : consequences for synaptic function and insulin release

    Författare :Jenny Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The process by which cells release substances through fusion of vesicles with the plasma membrane is called exocytosis. Regulated exocytosis needs to be tightly controlled in order to respond to the large variation in stimuli and demands for release of neurotransmitters, peptides and hormones. LÄS MER

  3. 2. The role of N-cadherin and S1P/S1P1 in pancreas development

    Författare :Jenny Johansson; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Organogenesis of epithelial organs requires interaction between epithelial and mesenchymal tissues. During pancreas development, mesenchyme-derived structures induce specification, growth and differentiation of pancreatic epithelial cells. LÄS MER

  4. 3. Drivers of polymorphism dynamics in pygmy grasshoppers

    Författare :Jenny Johansson; Anders Forsman; Jacob Höglund; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolutionary Biology; Evolutionsbiologi;

    Sammanfattning : In this thesis, I used colour polymorphism in pygmy grasshoppers as a model system to study the influence of selection, developmental plasticity, mating behaviour and gene flow on patterns of phenotypic and genetic diversity within and among populations in changing environments.Data for more than 5,000 individuals collected from natural populations showed that the incidence of black (melanic) pygmy grasshoppers was higher in burnt than in non-burnt areas, and rapidly declined over time within populations in post-fire environments.

  5. 4. The Impact of Growth Hormone and Gamma-Hydroxybutyrate (GHB) on Systems Related to Cognition

    Författare :Jenny Johansson; Mathias Hallberg; Fred Nyberg; Linda Fryklund; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth Hormone; Gamma-Hydroxybutyrate; GABAB; Opioids; Insulin-like growth factor 1; Rats; Central Nervous System; Autoradiography; Radioimmunoassay; ELISA; Water Maze; Open Field; Biological Research on Drug Dependence; Biologisk beroendeforskning;

    Sammanfattning : Drug dependence is a serious and increasing problem in our society, especially among adolescents. The use of the large variety of substances available can result in a range of physiological and psychological adverse effects on individuals and negative consequences on the society overall. LÄS MER

  7. 5. Genusgörande och läkarblivande : attityder, föreställningar och förväntningar bland läkarstudenter i Sverige

    Författare :Jenny Andersson; Katarina Hamberg; Pär Salander; Eva Johansson; Birgitta Hovelius; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gender bias; gender perspective; medical education; medical students; gender awareness; gender beliefs; gender norms; mixed methods; feminization of medicine; medical curricula; gender sensitivity; genus bias; genusperspektiv; läkarutbildning; läkarstudenter; genusmedvetenhet; föreställningar om kön; mixed method; feminisering; dold läroplan;

    Sammanfattning : The inclusion of a gender perspective in medicine has shown that gender is an essential factor in health and disease, in medical encounters and also in medical students’ educational environment. The aim of this study was to explore attitudes, preconceptions and norms regarding gender within medical education and processes of gender bias. LÄS MER
