  1. 11. Maternal Separation in Rats : An Experimental Model for Long-Term Effects of Early Life Experiences on Neurochemistry, Voluntary Ethanol Intake and Exploration and Risk Assessment Behavior

    Författare :Erika Roman; Ingrid Nylander; J. Dee Higley; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical pharmacology; Handling; Maternal Deprivation; Environment; Opioids; Dopamine; Alcohol; Stress; Concentric Square Field; Open Field; Elevated Plus-maze; Farmaceutisk farmakologi; Pharmaceutical pharmacology; Farmaceutisk farmakologi;

    Sammanfattning : The period of early life is important for the development of individual brain function and behavior. Human studies have shown altered vulnerability to develop psychopathology and/or excessive drug intake, possibly leading to dependence, as a consequence of early life experiences. LÄS MER

  3. 12. Free Movement of Persons and Social Security : Gender Implications of EC Regulation 1408/71

    Författare :Vicki Paskalia; Ulf Bernitz; Philippa Watson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Free Movement; Social Security; Co-ordination; European Community; Gender; European law; EU-rätt;

    Sammanfattning : The application of Regulation 1408/71 establishing a system of co-ordination of social security within the framework of the European Community is based on two criteria: economic activity and family/marriage. Work interruptions challenge the invocation of economic activity as an effective basis for social security rights. LÄS MER

  4. 13. Endogenous Opioids and Voluntary Ethanol Drinking : Consequences of Postnatal Environmental Influences in Rats

    Författare :Lisa Gustafsson; Ingrid Nylander; Erika Roman; Ryszard Przewlocki; Uppsala universitet; []
    Nyckelord :Pharmaceutical pharmacology; Maternal separation; Maternal deprivation; Handling; Isolation; Alcohol; Two-bottle model; Four-bottle model; MEAP; Dynorphin B; Nociceptin orphanin FQ; Radioimmunoassay; Farmaceutisk farmakologi;

    Sammanfattning : Genetic and environmental factors interact to determine the individual vulnerability to develop ethanol dependence. The neurobiological mechanisms underlying these processes are not fully understood. Endogenous opioid peptides have been suggested to contribute. LÄS MER

  5. 14. Genetic Aspects of Sexual Selection and Mate Choice in Salmonids

    Författare :Lars Forsberg; Mats Grahn; Jacob Höglund; Claus Wedekind; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; mate choice; Mhc; Major histocompatibility complex; class IIB; disassortative; assortative; microsatellite; outbreeding; supportive breeding; population; population genetics; Biologi; Biology; Biologi;

    Sammanfattning : The long-term genetic consequences of supportive breeding programs are not well understood. Nevertheless, stocking populations with hatchery-produced fish to compensate for losses of natural production are common practice, for example after constructions of hydroelectric power dams.

  7. 15. Effects of mixtures of endocrine disrupting chemicals – Thyroid disruption and behavioural effects in fish models

    Författare :Lina Birgersson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; endocrine disrupting chemicals; ecotoxicology; zebrafish; perch; locomotion; behaviour; thyroid disruption; EDC mixtures;

    Sammanfattning : Wildlife and humans are continuously exposed to thousands of man-made compounds, including chemicals that are able to act as endocrine disruptors (EDCs). These pollutants are able to affect vital processes including brain development, reproduction, metabolism and growth. LÄS MER
