1. Liquid Chromatography – Mass Spectrometry Analysis of Short-lived Tracers in Biological Matrices : Exploration of Radiotracer Chemistry as an Analytical Tool
Sammanfattning : Liquid chromatography – mass spectrometry (LC-MS) methods were developed for the analysis of positron emission tomography (PET) radiotracers in biological matrices. Additionally, radiotracer chemistry was explored as an analytical tool for supporting LC-MS method development and imaging molecular interactions in miniaturised chemical analysis systems. LÄS MER
2. Synthesis of Organofluorine Compounds and Allenylboronic Acids - Applications Including Fluorine-18 Labelling
Sammanfattning : This work is focused on two areas: the chemistry of organofluorine and organoboron compounds. In the first chapter, a copper-catalysed synthesis of tri- and tetrasubstituted allenylboronic acids is presented. Extension of the same method leads to allenylboronic esters. LÄS MER
3. Design and Evaluation of Radiolabeled Affibody Tracers for Imaging of HER2-expressing Tumors
Sammanfattning : The growing understanding of tumor biology and the identification of tumor specificgenetic and molecular alterations, such as the overexpression of human epidermal growthfactor receptor 2 (HER2), opens up for personalization of patient management using targeted therapies. However, this puts stringent demands on the diagnostic tools usedto identify patients that are likely to respond to a particular treatment. LÄS MER
4. Pre-Clinical Evaluation of a Novel Radiotracer for the Diagnosis of DVT and Pulmonary Embolism
Sammanfattning : Deep vein thrombosis (DVT) and pulmonary embolism (PE) are different aspects of a single condition, venous thrombo-embolic disease (VTE), a major cause of morbidity and mortality in the western world. Rapid diagnosis is critical, as timely medical intervention can have a substantial beneficial effect on the mortality rate. LÄS MER
5. Migration of molecules in the brain : focus on the extracellular space and the cerebrospinal fluid
Sammanfattning : Three different molecules and three different experimental models were used to study the migration of molecules in the rat brain: a neurotransmitter- dopamine, an extracellular market- mannitol, and a neuropeptide beta-endorphin. Two models in vivo were used to study the diffusion and migration of molecules: dual-probe rnicrodialysis in the striatum, and direct intrastriatal microinjections followed by cerebrospinal fluid sampling from the cisterna magna.
