  2. 1. Improved Neuropeptide Identification : Bioinformatics and Mass Spectrometry

    Author : Maria Fälth Savitski; Per Andrén; David Fenyö; Per Svenningsson; Ronald Beavis; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; neuropepides; database; peptide identification; peptide fragmentation; mass spectrometry; tandem mass spectromerty; Bioinformatics; Bioinformatik;

    Abstract : Bioinformatic methods were developed for improved identification of endogenous peptides using mass spectrometry. As a framework for these methods, a database for endogenous peptides, SwePep, was created. It was designed for storing information about endogenous peptides including tandem mass spectra. READ MORE

  5. 3. Laser-based absorption spectrometry : development of NICE-OHMS towards ultra-sensitive trace species detection

    Author : Florian Schmidt; Ove Axner; Livio Gianfrani; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; absorption spectrometry; trace species detection; fiber laser; modulation; cavity-enhanced spectroscopy; optical saturation; laser frequency stabilization; free-spectral-range; Physics; Fysik;

    Abstract : Laser-based absorption spectroscopy (AS) is a powerful technique for qualitative and quantitative studies of atoms and molecules. An important field of use of AS is the detection of species in trace concentrations, which has applications not only in physics and chemistry but also in biology and medicine, encompassing environmental monitoring, regulation of industrial processes and breath analysis.
