2. 1. Imaging and Quantification of Brain Serotonergic Activity using PET

   Author : Pinelopi Lundquist; Margareta Hammarlund-Udenaes; Per Hartvig; Gunnar Blomquist; Paul Cumming; Uppsala universitet; []
   Keywords : Pharmacokinetics Pharmacotherapy; Brain serotonin; Neurotransmitter release; Neurotransmitter synthesis; Positron emission tomography; Tracer validation; Tracer modelling; Farmakokinetik Farmakoterapi;

   Abstract : This thesis investigates the potential of using positron emission tomography (PET) to study the biosynthesis and release of serotonin (5HT) at the brain serotonergic neuron. As PET requires probe compounds with specific attributes to enable imaging and quantification of biological processes, emphasis was placed on the evaluation of these attributes. READ MORE

4. 2. Blood-Brain Barrier Transport : Investigation of Active Efflux using Positron Emission Tomography and Modelling Studies

   Author : Stina Syvänen; Margareta Hammarlund-Udenaes; Mats Bergström; Gunnar Blomquist; Jashvant Unadkat; Uppsala universitet; []
   Keywords : Pharmaceutical biosciences; pharmacokinetics; P-glycoprotein; blood-brain barrier; modelling; PET; active efflux; species differences; [11C]verapamil; drug development; Farmaceutisk biovetenskap;

   Abstract : This thesis examines the transport of exogenous molecules across the blood-brain barrier (BBB), focusing on active efflux, using positron emission tomography (PET), computer simulation and modelling. P-glycoprotein (P-gp) inhibition was studied using [11C]verapamil and [11C]hydroxyurea was investigated as a new marker for active efflux transport. READ MORE
