1. Chemical signals in interactions between Hylobius abietis and associated bacteria
Sammanfattning : The pine weevil (Hylobius abietis L.) is one of the two topmost economically important insect pests in Swedish conifer forests. The damage increase in areas were the silvicultural practice is to use clear cuttings were the insects gather and breed. LÄS MER
2. Molecular Imaging of Diabetic Kidney Tissue and Binding Studies of Proinsulin C-peptide
Sammanfattning : Diabetic kidney disease is a serious complication of diabetes with a complex and incompletely understood pathology. In this work, the molecular changes in diabetic rat kidneys at a very early disease stage were studied using nanospray desorption electrospray ionisation mass spectrometry imaging. LÄS MER
3. Metabolic Studies with Liquid Separation Coupled to Mass Spectrometry
Sammanfattning : Metabolism is the sum of all chemical processes with the purpose to maintain life, as well as enable reproduction, in a living organism. Through the study of metabolism, increased understanding of pharmacological mechanisms and diseases can be achieved. LÄS MER
4. Synthesis and spectroscopic characterization of emerging synthetic cannabinoids and cathinones
Sammanfattning : The application of different analytical techniques is fundamental in forensic drug analysis. In the wake of the occurrence of large numbers of new psychoactive substances possessing similar chemical structures as already known ones, focus has been placed on applied criteria for their univocal identification.

5. Metal Particles – Hazard or Risk? Elaboration and Implementation of a Research Strategy from a Surface and Corrosion Perspective
Sammanfattning : Do metal particles (including particles of pure metals, alloys, metal oxides and compounds) pose a hazard or risk to human health? In the light of this question, this thesis summarizes results from research conducted on metal particles, and describes the elaboration and implementation of an in vitro test methodology to study metal release from particles through corrosion and dissolution processes in synthetic biological media relevant for human exposure through inhalation/ingestion and dermal contact. Bioaccessible metals are defined as the pool of released metals from particles that potentially could be made available for absorption by humans or other organisms. LÄS MER
