16. Metabolite Profiling of Drugs using Mass Spectrometry : Identification of analytical targets for doping control and improvements of the metabolite search process
Sammanfattning : Doping is defined as the use of prohibited substances or methods by the World Anti-Doping Agency and the aim with doping control analysis is to detect the use of these illicit substances or methods. Substances that are prohibited in human or equine sports have either a positive or negative impact on the performance. LÄS MER
17. Development of Methods for Protein and Peptide Analysis Applied in Neuroscience Utilizing Mass Spectrometry
Sammanfattning : This thesis describes the utilization of the matrix-assisted laser desorption ionization mass spectrometry (MALDI MS) and electrospray ionization (ESI) MS techniques for analysis of complex brain tissue samples. Direct molecular profiling of biological samples using MALDI MS is a powerful tool for identifying phenotypic markers. LÄS MER
18. Atomic laser resonance ionization mass spectrometry
Sammanfattning : .... LÄS MER
19. Advanced Mass Spectrometry Imaging in Neuropharmacology
Sammanfattning : Mass spectrometry imaging (MSI) has emerged as a valuable approach for mapping multiple molecular species in sections of diverse tissues. It enables simultaneous detection of numerous compounds (from neurotransmitters to small proteins) in the brain at relatively high lateral resolution (>5 μm) on a routine basis. LÄS MER
20. Electrophoretic focusing in microchannels combined with mass spectrometry : Applications on amyloid beta peptides
Sammanfattning : Analysis of low-abundance components in small samples remains a challenge within bioanalytical chemistry, and new techniques for sample pretreatments followed by sensitive and informative detection are required. In this thesis, procedures for preconcentration and separation of proteins and peptides in open microchannels fabricated on silicon microchips are presented. LÄS MER
