  1. 6. Levodopa- and Neuroleptic-Induced Dyskinesias : Studies on Pharmacological Modification and Processing of Opioid Neuropeptides

    Författare :Rebecka Klintenberg; Alan Crossman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological research on drug dependence; Opioid peptides; dyskinesia; Parkinson s disease; mass spectrometry; metabolism; Biologisk beroendeforskning; Biological research on drug dependence; Biologisk beroendeforskning; biologisk beroendeforskning; Biological Research on Drug Dependence;

    Sammanfattning : Dyskinesias or abnormal involuntary movements are a debilitating complication of long-term levodopa treatment of Parkinson’s disease (PD) that is widely experienced and may compromise the efficacy of the drug therapy. Tardive dyskinesia is another important adverse effect seen with antipsychotic drug treatment. LÄS MER

  3. 7. Molecular Adaptations in the Endogenous Opioid System in Human and Rodent Brain

    Författare :Muhammad Zubair Hussain; Georgy Bakalkin; Anita Hansson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endogenous Opioid System; Dynorphins; Lateralization; Alcohol Dependence; Emotions; Traumatic Brain Injury; Anterior Cingulate Cortex; Dorsal Striatum; Neuroscience; Neurovetenskap;

    Sammanfattning : The aims of the thesis were to examine i) whether the endogenous opioid system (EOS) is lateralized in human brain areas involved in processing of emotions and pain; ii) whether EOS responses to unilateral brain injury depend on side of lesion, and iii) whether in human alcoholics, this system is involved in molecular adaptations in brain areas relevant for cognitive control of addictive behavior and habit formation.The main findings were that (1) opioid peptides but not opioid receptors and classic neurotransmitters are markedly lateralized in the anterior cingulate cortex involved in processing of  positive and negative emotions and affective component of pain.

  4. 8. Imaging of the brain opioid system in amphetamine dependence

    Författare :Joar Guterstam; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Amphetamine dependence is a global health problem, often giving rise to severe medical and social complications in affected individuals. Unfortunately, there is still limited evidence for any specific treatment that would help amphetamine dependent patients to avoid relapse. LÄS MER

  5. 9. Opioidberoende : en studie om beroendevården och det sociala sammanhangets betydelse

    Författare :Marcus Nilsson Blom; Björn Blom; Mojgan Padyab; Daniel Törnqvist; Lena Lundgren; Björn Johnson; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Opioid dependence; medication assisted treatment; compulsory care; social cohesion; register-based research; social work;

    Sammanfattning : Opioid dependence is highly associated with health problems relating to physical health (infectious diseases) as well as mental health (depression, anxiety, antisocial behavior). In addition, research has found an association between use of opioids and increased risk of premature death as a consequence of overdose or other circumstances, such as suicide. LÄS MER

  7. 10. In vitro and postmortem studies of the brain opioid system : association to opiate dependence

    Författare :Parisa Zarnegar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Opioid system; brain; gene expression; amygdala; hippocampus; opiate dependence;

    Sammanfattning : Opioids such as heroin are highly addictive illicit drugs. The μ opioid receptor (MOR) plays a central role in mediating the effects of opiates and related opioid. LÄS MER
