1. 1. Visualization of Peripheral Pain Generating Processes and Inflammation in Musculoskeletal Tissue using [11C]-D-deprenyl PET

   Författare :Mikko Aarnio; Torsten Gordh; Jens Sörensen; Magnus Peterson; Lars Ståhle; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ankle injuries; arthritis; binding site; binding target; carbon-11; deprenyl; high-throughput screening; inflammation; monoamine oxi-dase; pain; PET; whiplash; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

   Sammanfattning : An objective visualization and quantification of pain-generating processes in the periphery would alter pain diagnosis and represent an important paradigm shift in pain research. Positron emission tomography (PET) radioligand [11C]-D-deprenyl has shown an elevated uptake in painful inflammatory arthritis and whiplash-associated disorder. LÄS MER

3. 2. Molecular Pharmacology and Structure Function Modelling of the Leukotriene B4 Receptor BLT1

   Författare :Alan Sabirsh; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Pharmacological sciences; fluidity; redox; chemotaxis; luciferase; calcium; ligand binding; point mutation; modelling; antibody; BLT1; leukotriene; pharmacology; GPCR; G-protein; receptor;

   Sammanfattning : Leukotrienes are membrane derived bioactive lipids that play an important role in immune responses by initiating and maintaining the inflammatory responses. Leukotriene B4 (LTB4) released at the site of an inflammatory response attracts, activates and prolongs the life of leukocytes and lymphocytes. LÄS MER

4. 3. Amino acid transport and receptor binding properties in neuropsychiatric disorders using the fibroblast cell model

   Författare :Jessica Johansson; Nikolaos Venizelos; Lars Oreland; Örebro universitet; []
   Nyckelord :Fibroblasts; Bipolar disorder; ADHD; Tyrosine; Tryptophan; Alanine; Transport; mAChRs; Biomedicin; Biomedicine;

   Sammanfattning : Altered transport of the catecholamines and serotonin precursor amino acids tyrosine and tryptophan, might be one explanation for the dysfunctional neurotransmission implicated in the pathophysiology of bipolar disorder and Attention Deficit/Hyperactivity Disorder (ADHD). In previous studies, an altered amino acid transport has been found in schizophrenia and autism, when using the fibroblast cell model. LÄS MER

5. 4. A PET study on dopamine and serotonin receptor binding in the primate brain : challenges with antipsychotic drugs and amphetamine

   Författare :Yuan-Hwa Chou; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The brain imaging technique positron emission tomography (PET) has been applied to study dopamine and serotonin neurotransmission. In schizophrenia research, an important observation is that patients with schizophrenia, when compared with controls, have higher amphetamine induced dopamine release in the striatum. LÄS MER

7. 5. Synthesis and evaluation of new PET radioloigands for imaging central norepinephrine transporters

   Författare :Magnus Schou; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :PET; Radioligand; NET; Brain;

   Sammanfattning : The noradrenergic (NE), serotonergic (5-HT) and dopaminergic (DA) neurotransmission systems all have specific proteins responsible for the regulation of synaptic concentrations of neurotransmitter in the central nervous system (CNS) and in the periphery. Several reports have shown that the expression of these proteins, the monoamine transporters, within the CNS, may be altered in patients with certain neurodegenerative or neuropsychiatric disorders.
