6. Analytical Aspects of Atmospheric Pressure Ionisation in Mass Spectrometry
Sammanfattning : The actual signal recorded with an analytical instrument is not always a true reflection of the analysed sample. In this thesis a further insight of the atmospheric pressure ionisation processes electrospray (ESI) and atmospheric pressure chemical ionisation (APCI) has been endeavoured, to provide a deeper understanding of and ways to minimize this bias.

7. Anti-cancer effects of bioactive compounds from rose hip fruit in human breast cancer cell lines : carotenoids, triterpenes, and ascorbate evaluated singly or in combination
Sammanfattning : Rose hips have long been used in human diets as a food ingredient and supplement. Their multiple medical properties, which have been attributed to their abundant carotenoid composition, have attracted widespread scientific attention. This thesis examined the carotenoid composition in rose hips from five rose species. LÄS MER
8. Development of Methods for Measuring Protein C Inhibitor and Antithrombin: Use of Monoclonal Antibodies against the Reactive Center Loop-Inserted Forms of the Serpins
Sammanfattning : Protein C inhibitor (PCI) and antithrombin (AT) are serine protease inhibitors (serpins) that are involved in the regulation of coagulation. Like other inhibitory serpins, PCI and AT adopt different structural conformations that are related to their functions. LÄS MER
9. Development and Evaluation of a Denuder-Filter System Designed for Sampling Diisocyanate Aerosols
Sammanfattning : There are many occupational environments in which isocyanates or PUR-products are used, produced or processed. During these operations there is always a risk of isocyanate exposure, which may lead to severe health problems. Isocyanates principally affect the respiratory system and they are the main cause of occupational asthma. LÄS MER
