  1. 1. The role of insulin signaling during development, reproductive diapause and aging in Drosophila Melanogaster

    Författare :Sifang Liao; Dick Nässel; Heinrich Dircksen; Mark Brown; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; insulin-like peptides; reproductive diapause; behavioral senescence; neuromodulator; lifespan; funktionell zoomorfologi; Functional Zoomorphology;

    Sammanfattning : The insulin/insulin-like growth factor signaling pathway exists from invertebrates to vertebrates and it can regulate various biological processes, including development, metabolism, stress resistance and lifespan. In Drosophila, eight insulin-like peptides (DILP1-8) have been found. LÄS MER

  3. 2. On the cerebrospinal fluid disposition and neurobiological role of cholecystokinin in man

    Författare :Tove Gunnarsson; Conny Nordin; Erik Widerlöv; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Cholecystokinin (CCK) is the most abundant neuropeptide in the brain, where it acts as a neurotransmitter and neuromodulator. The tetrapeptide CCK-4 and the octapeptide CCK-8 have been implicated in various behavioural and physiological functions, such as anxiety, pain and satiety. LÄS MER

  4. 3. Synaptic transmission and synaptic plasticity in the mouse striatum

    Författare :Sietske Schotanus; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The striatum is the major input nucleus of the basal ganglia and can be subdivided into a dorsal part and a ventral part that is also named nucleus accumbens (NAc). The dorsal part is involved in motor control and habit learning whereas the ventral part is mostly associated with rewardmotivated behaviors. LÄS MER

  5. 4. Oxygen sensing in Caenorhabditis elegans

    Författare :Lina Zhao; Changchun Chen; Simon Tuck; Helena Edlund; Marc Pilon; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; C. elegans; acute hypoxia; G-protein; mitochondrial ROS; neuropeptide; GPCR;

    Sammanfattning : Sufficient supply of oxygen (O2) to tissue is essential for survival of aerobicanimals. In mammals, there are constant homeostatic regulation mechanisms that act on different time scales to maintain optimal O2 delivery to tissues. The ability to detect and respond to acute oxygen shortages is indispensable to aerobic life. LÄS MER

  7. 5. Analgetic and algetic effects of adenosine in healthy volunteers and patients with coronary disease

    Författare :Bita Sadigh; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Angina pectoris; silent myocardial ischemia; opioid; gender; preconditioning;

    Sammanfattning : Background: Adenosine is a bimodal neuromodulator with algesic and analgesic effects. The different effects of adenosine are partly due to the route of administration. Low-dose adenosine infusion induces analgesia at the same magnitude as morphine, while adenosine as bolus injection induces chest pain, similar in character as angina pectoris. LÄS MER
