    Sammanfattning : Present-day Mars is a cold and dry planet with a thin CO2-dominated atmosphere comprising only a few ­­­mbar pressure at low altitudes. However, the Martian surface is marked with valley networks, hydrated mineral clays, carbonates and the remains of deltas and meandering rivers, i.e. LÄS MER

    Sammanfattning : oday about half of the world's population owns the microwave producing mobile phones. The blood-brain barrier (BBB) protects the mammalian brain from potentially harmful substances circulating in the blood. LÄS MER

  5. 19. Immune-to-Brain Signaling in Fever : The Brain Endothelium as Interface

    Författare :Elahe Mirrasekhian; David Engblom; Anders Blomqvist; Simin Mohseni; Tomas Deierborg; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Fever is a brain-regulated elevation of body temperature that occurs in response to infectious and non-infectious stimuli. During inflammatory episodes, circulating cytokines that are released by activated immune cells, trigger the induction of cyclooxygenase (COX)-2 in the ventromedial preoptic area of the hypothalamus (the thermoregulation center).

  7. 20. Imaging brain aromatase by using PET : A way to study anabolic steroid abuse

    Författare :Kayo Takahashi; Mats Bergström; Bengt Långström; Yasuyoshi Watanabe; Torbjörn Bäckström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aromatase; brain; molecular imaging; PET; [11C]Vorozole; amygdala; hypothalamus; anabolic-androgenic steroids; abuse; [18F]Vorozole analogs; Neuroscience; Neurovetenskap;

    Sammanfattning : Aromatase is an enzyme that facilitates the conversion of androgens to estrogens and may play a role in mood and mental status. The main theme of this thesis is the imaging of brain aromatase by use of the PET technique. The PET tracer for aromatase, 11C-labeled vorozole (VOZ) was developed and evaluated by with in vitro and in vivo methods. LÄS MER
