21. Animal movement on short and long time scales and the effect on genetic diversity in cold-adapted species
Abstract : The genetic diversity in modern species is strongly affected by contemporary gene flow between populations, which in turn is governed by individual dispersal capacities and barriers in the landscape. However, current patterns of variation have also been shaped by movement over longer time-scales, such as the successive shifts in species distributions that have occurred during past climate changes.

22. 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

23. Visualizing and profiling tissue lipids by ToF-SIMS imaging mass spectrometry
Abstract : Time-of-flight secondary ion mass spectrometry (ToF-SIMS) is an emerging surface analytical method for chemical microanalysis of biological samples. While much work has been done with artificial materials and some with cultured cells and animal tissue, very little ToF-SIMS work has been done so far with clinically relevant tissue samples.

24. Molecular, micro- and ultrastructural investigations of labile tissues in deep time
Abstract : This thesis comprises investigations of microstructures and molecular remains, preserved in a variety of fossil specimens. The results are presented in six papers, collectively aiming to thoroughly examine fossil traces of such remains by employing a combination of both established and relatively new analytical methods.

25. Combining mass spectrometric tissue imaging with conventional histology : focus on Alzheimer’s disease
Abstract : Historically, most scientific discoveries have been accompanied by previous technological innovation. Representative examples are the introduction of gene sequencing technologies, which allowed for the mapping of the human genome, or the constant improvement in the microscopy field that lead to the introduction of modern multiphoton imaging techniques, allowing for live imaging of body organs in animal specimens.
