  1. 1. Selectivity in NMR and LC-MS Metabolomics : The Importance of Sample Preparation and Separation, and how to Measure Selectivity in LC-MS Metabolomics

    Author : Albert Elmsjö; Curt Pettersson; Torbjörn Arvidsson; Thomas Moritz; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Metabolomics; NMR; LC-MS; HILIC; UHPLC; Q-ToF; selectivity; co-feature ratio; method evaluation; data evaluation; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

    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

  3. 3. Multidetection and chemometrics in flow injection analysis

    Author : Robert Tryzell; Elo H. Hansen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Analytical Chemistry; analytisk kemi;

    Abstract : An ideal method for the determination of ions in aqueous solutions should be fast, inexpensive, simple, reliable and require small sample volumes. Flow Injection Analysis (FIA) is in many respects such an ideal method but it is too often limited to the determination of one analyte at a time. READ MORE

  4. 4. Electrospray Ionization Mass Spectrometry for Determination of Noncovalent Interactions in Drug Discovery

    Author : Kurt Benkestock; Johan Roeraade; Renato Zenobi; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; electrospray ionization; drug discovery; noncovalent interaction; complexes; human serum albumin HSA ; fatty acid binding protein FABP ; ribonuclease; ligand screening; Analytical chemistry; Analytisk kemi;

    Abstract : Noncovalent interactions are involved in many biological processes in which biomolecules bind specifically and reversibly to a partner. Often, proteins do not have a biological activity without the presence of a partner, a ligand. READ MORE

  5. 5. A Framework for Evaluation of Flood Management Strategies

    Author : Karin Hansson; Love Ekenberg; Mats Danielson; Anna Vári; Stockholms universitet; []
    Keywords : flood; decision; multi criteria; simulation; evaluation; data- och systemvetenskap; Computer and Systems Sciences;

    Abstract : During the last decades, a great deal of attention has been focused on the financial risk management of natural disasters. The reason is that the economic losses from floods, windstorms, earthquakes and other disasters in both the developing and developed countries are escalating dramatically. READ MORE
