6. Analytical developments and applications of ambient mass spectrometry imaging : Visualizing challenging analytes and understanding chemical mechanisms of ischemic stroke
Sammanfattning : Bioanalytical methods that provide spatial information on molecular distributions are important for deep understanding of chemical mechanisms in health and disease. For instance, the localized action of drugs and metabolites can provide valuable information on metabolism in specific cellular regions, which would not be possible with bulk analysis. LÄS MER
7. 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
8. New Materials and Improved Ambient Techniques in Mass Spectrometry
Sammanfattning : Mass spectrometry (MS) is used in several fields, e.g. biology, environmental monitoring, medicine and forensics due to excellent qualitative and quantitative capabilities. The development of new instrumental setups and ionization sources is crucial to analyze a variety of compounds at trace levels. LÄS MER
9. Applications of nanospray desorption electrospray ionization mass spectrometry : In situ lipid and metabolite analysis from cells to tissue
Sammanfattning : Ambient mass spectrometry (MS) has proved to be an important addition to the bioanalytical toolbox. These methods perform analyte sampling and ionization under atmospheric pressure, and require very little sample preparation other than the sampling process in front of the machine. LÄS MER
10. Organic Phosphorus Compounds in Aquatic Sediments : Towards Molecular Identification with Mass Spectrometry
Sammanfattning : Phosphorus (P) regulates trophic status in most aquatic systems. However, only bioavailable P contributes to primary production. In most lakes and shallow seas, mineralisation of sediment P into its bioavailable form and its release to the water column is important for maintaining primary production. LÄS MER
