21. 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
22. Development of MALDI Mass Spectrometry Imaging Methods for Probing Spatial Lipid Biochemistry of Amyloid Plaques in Alzheimer's Disease
Sammanfattning : Alzheimer’s disease (AD) is the most prevalent cause of neurodegenerative dementia. Aggregation of amyloid β (Aβ) peptides into extracellular Aβ plaques is one of the major neuropathological features of AD. LÄS MER
23. Mass spectrometry based analysis of drugs, neurotransmitters and lipids in invertebrate model systems
Sammanfattning : Mass spectrometry (MS) is one of the most universal analytical techniques due to its label-free detection principle and high chemical specificity, high selectivity, and sensitivity. MS is diverse with many different types of systems to meet different analytical demands from various research areas. LÄS MER
24. Mass spectrometry of biopolymers based on ion-induced desorption
Sammanfattning : Various aspects of biopolymer molecular characterization by their molecular masses havebeen studied, with emphasis on ion-induced desorption and time-of-flight mass Spectrometry(TOF MS). Limitations of the average-isotopic mass concept, as well as the utility ofaccurate monoisotopic mass measurements for deriving amino-acid and elementalcompositions, are discussed. LÄS MER
