  1. 1. Nuclear medicine methods in idiopathic Parkinsonism : pre- and postsynaptic dopamine SPECT

    Author : Susanna Jakobson Mo; Katrine Åhlström Riklund; Anne Larsson Strömvall; Lars Forsgren; Rimma Axelsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear medicine; SPECT; 123I-FP-Cit; 123I-IBZM; dopamine; parkinsonism; Parkinson’s disease; multiple system atrophy; progressive supranuclear palsy; Radiology; radiologi;

    Abstract : Background: Single photon emission computed tomography (SPECT) with dopamine transporter (DAT) and dopamine D2 receptor (D2R) ligands can visualise the integrity of the nigrostriatal dopamine system. Parkinson’s disease (PD) and the atypical parkinsonian diseases (APD), progressive supranuclear palsy (PSP) and multiple system atrophy (MSA), have similar symptoms and dopamine depletion, but differ in pharmacological response and prognosis.

  2. 2. On the influence of dopamine-related genetic variation on dopamine-related disorders

    Author : Olle Bergman; Göteborgs universitet; []
    Keywords : dopamine; neurodevelopment; amygdala; schizophrenia; Parkinson s disease; social anxiety disorder; ADHD; PITX3; LMX1A; LMX1B; BDNF; DAT; SNP; genes; genetics; BDNF;

    Abstract : Rationale: Dopamine synthesizing neurons are involved in a wide variety of functions. The most prominent dopamine pathways originate in the midbrain. The development, function and survival of these dopaminergic neurons are under the influence of numerous transcription and neurotrophic factors. READ MORE

  3. 3. Anabolic androgenic steroids and central monoaminergic systems : Supratherapeutic doses of nandrolone decanoate affect dopamine and serotonin

    Author : Carolina Birgner; Lena Bergström; Anna Kindlundh-Högberg; Fred Nyberg; Stefan Brené; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; anabolic androgenic steroids; nandrolone decanoate; dopamine; serotonin; rat; central nervous system; Pharmacology; Farmakologi;

    Abstract : Supratherapeutic doses of anabolic androgenic steroids (AASs) are administered, not only as performance-enhancing drugs in the world of sports, but also in order to modify behaviour. AAS abusers are at risk of developing serious physical and psychological side effects such as dependence and aggressive behaviour. READ MORE

  4. 4. Imaging serotonin and dopamine transporters in social anxiety disorder : Characterization, treatment and expectancy effects

    Author : Olof Hjorth; Tomas Furmark; Andreas Frick; Eduard Maron; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; PET; serotonin; dopamine; placebo; SSRI; CBT; MRI; Psychology; Psykologi; Psychiatry; Psykiatri; Radiology; Radiologi;

    Abstract : The monoamines serotonin and dopamine are likely to be involved in the pathophysiology of social anxiety and other affective disorders, but their respective contributions and putative interactions in the causes and cures of these disorders are still not well understood. It is also largely unknown if and how expectations of treatment success affect brain neurochemistry and neural activations, and if expectations interact with antidepressants like selective serotonin reuptake inhibitors (SSRIs).

  5. 5. Cytochrome P450 2E1 - relevance for central dopamine neurotransmission and Parkinson's disease

    Author : Haydeh Niazi Shahabi; Göteborgs universitet; []
    Keywords : cytochrome P450 2E1; dopamine; substantia nigra; polymorphism; alternative splicing;

    Abstract : Introduction: The enzyme cytochrome P450 2E1 (CYP2E1) has been found in dopamine (DA) containing brain regions that are of relevance for Parkinson?s disease (PD), and is known to generate reactive oxygen species (ROS), toxic molecules that have been implicated in the degeneration of DA neurones. In addition, previous investigations have indicated that inhibition of CYP2E1 increases extracellular DA in the substantia nigra, a nucleus which degenerates in PD. READ MORE
