11. Mass Spectrometric Analysis of Oxylipins : Application to Cytochrome P450-Dependent Metabolism
Abstract : Cytochrome P450 (CYP) family 4 constitutes monoxygenases responsible for hydroxylation of fatty acids and other lipids. For example, CYP4F3 metabolizes leukotrienes and CYP4F8 prostaglandin H. Importantly, six of the twelve CYP4 enzymes are orphans, i.e. READ MORE

12. Development of analytical methods for the determination of the small molecule component of complex biological systems
Abstract : The research field of untargeted metabolomics aims to determine the relative abundance of all small metabolites in a biological system in order to find biomarkers or make biological inference with regards to the internal or external stimuli. This is no trivial aim, as the small metabolites are both vast in numbers and extremely diverse in their chemical properties. READ MORE

13. Drug Metabolites Formed by Cunninghamella Fungi : Mass Spectrometric Characterization and Production for use in Doping Control
Abstract : This thesis describes the in vitro production of drug metabolites using fungi of the Cunninghamella species. The metabolites were characterized with mainly liquid chromatography-mass spectrometry using ion-trap and quadrupole-time-of-flight instruments. A fungal in vitro model has several advantages e.g. READ MORE

14. Investigation of degradation of toxic substances in fungal cultures by mass spectrometric techniques
Abstract : Micropollutants in water are biological or chemical contaminants that are present in ground and surface waters in trace quantities. They are a result of human activity and include pharmaceutically active compounds (PhACs) and endocrine disrupting compounds (EDCs). READ MORE

15. Detection and Structure Elucidation of Drug Metabolites in Biological Samples using HPLC-MS/MS Techniques
Abstract : This thesis describes the structure elucidation of drug metabolites in biological samples by the use of high performance liquid chromatography (HPLC) atmospheric pressure ionization (API) tandem mass spectrometry (MS/MS). Due to their different advantages, various mass analyzers have been used in the different experiments. READ MORE
