1. Selectivity in NMR and LC-MS Metabolomics : The Importance of Sample Preparation and Separation, and how to Measure Selectivity in LC-MS Metabolomics
Abstract : Until now, most metabolomics protocols have been optimized towards high sample throughput and high metabolite coverage, parameters considered to be highly important for identifying influenced biological pathways and to generate as many potential biomarkers as possible. From an analytical point of view this can be troubling, as neither sample throughput nor the number of signals relates to actual quality of the detected signals/metabolites. READ MORE

2. Efficiency and Selectivity in the Chlorate Process
Abstract : This licentiate thesis presents experimental studies concerning two parts of the electrochemical cell in the chlorate process: a cathode and an anode.Newly synthesized MnOx electrodes were investigated for the cathodic reaction, hydrogen evolution reaction (HER) in the chlorate process.

5. Muscarinic receptors and urinary bladder selectivity : Properties that determine the organ selectivity of compounds
Abstract : Urinary bladder contraction is mainly mediated by activation of muscarinic acetylcholine receptors (mAChR). Muscarinic antagonists are often effective in treatment of unstable bladder. The effectiveness of this treatment has often been limited by side effects as dry mouth. READ MORE
