  1. 16. Neurobiological basis of the nicotine withdrawal reaction : an experimental analysis

    Författare :Bengt E Hildebrand; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :rat; nicotine; nicotine withdrawal; behavior; locomotor activity; microdialysis; intracerebral injections; mesolimbocortical; dopamine; ventral tegmental area; nucleus accumbens; amygdala; immediate-early genes; c-fos;

    Sammanfattning : The mesolimbocortical dopamine (DA) system is pivotal for the mediation of the reinforcing effects of many dependence-producing drugs. It consists of cell bodies in the ventral tegmental area (VTA) that project to e.g. the nucleus accumbens (NAC), the central nucleus of amygdala (CNA) and the medial prefrontal cortex. LÄS MER

  3. 17. Striatal adenosine A2A receptors

    Författare :Per Svenningsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :caffeine; adenosine; A2A receptors; dopamine receptors; striatum; basal ganglia; immediate early genes; c-fos; NGFI-A; DARPP-32; in situ hybridization;

    Sammanfattning : The nucleoside adenosine exerts a modulatory action in the central nervous system by activating G-protein coupled receptors. Four such receptors are cloned and pharmacologically characterized: A1, A2A, A2B and A3. Caffeine, the most widely consumed psychostimulant, acts as an adenosine receptor antagonist predominantly on the first two. LÄS MER

  4. 18. Behavioural and biochemical pharmacology of adenosine/dopamine receptor/receptor interaction

    Författare :Roberto Rimondini-Giorgini; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Adenosine; A; receptors; A2A receptors; dopamine; D1 receptors; D2 receptors; mGluR receptors; striatum; immediately early genes; c-fos; junB; NGFI-A; microdialysis; receptor binding; in situ hybridisation;

    Sammanfattning : The neurotransmitter dopamine seems to be involved in neuropsychiatric diseases such as schizophrenia and Parkinson's disease. Direct blockade of dopamine receptors of the D2 subtype has been the hallmark of pharmacotherapy for schizophrenia since early 1950s. LÄS MER

  5. 19. Perinatal asphyxia in the rat : a morphological and functional analysis of the dopamine systems and dopamine-mediated behaviours in a novel experimental model

    Författare :Yong Chen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Rat; Perinatal asphyxia; Dopamine; Noradrenaline; Dopamine receptors; Substantia nigra; Ventral tegmental area; Striatum; Accumbens nucleus; Locomotor activity; Attention disorders; bFGF; Fos; pH; pyruvate; lactate; glutamate; aspartate.;

    Sammanfattning : Asphyxia during labour in the human being is one of the important paediatric complications which can lead to various degree of injuries in the central nervous system. No efficient therapy is available at present. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Activity-based working; ABW; New ways of working NWW ; hot-desking; clean desk; office policies; workspace; office layout; office design; office planning process; organizational change; conceptual framework for office design; office planning; Aktivitetsbaserade kontor; ABW; Nya sätt att arbeta NWW ; flexibelt arbete; förhållningsregler; kontorsutformning; organisationsförändring; konceptuellt ramverk för kontorsplanering; planeringsprocessen; Technology and Health; Teknik och hälsa;

    Sammanfattning : Background: In recent years, there has been a reported increase in organizations relocating to Activity-based Flexible Offices (A-FOs) worldwide. The idea of A-FOs is to offer work conditions suitable for the workforce’s tasks and individual preferences. LÄS MER
