    Sammanfattning : Breath gas analysis is a promising approach for non-invasive medical diagnostics and physiological monitoring. Real-time, breath-cycle resolved biomarker detection facilitates data interpretation and has the potential to improve the diagnostic value of breath tests as exhalation profiles carry spatiotemporal information about biomarker origin and gas exchange in the respiratory tract.

    Sammanfattning : Mucosal inflammation and airway hyperreactivity are regulated by hundreds of different mediators. The recent discovery of gaseous mediators, produced and active within the airways, opens new possibilities for identification of therapeutic targets and ways to monitor airway inflammation. LÄS MER

  3. 3. Continuously tunable narrow-linewidth fiber lasers

    Författare :Xiong Yang; Valdas Pasiskevicius; Fredrik Laurell; Magnus Engholm; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Fiber laser; Optik och fotonik; Optics and Photonics;

    Sammanfattning : Narrow linewidth tunable fiber lasers have become an important tool in research and in-field applications thanks to their high beam quality, great spectral performance, compact structure and environmental robustness. Many methods have been introduced and developed throughout decades to fulfill the need for rapid wavelength adjustment of these fiber lasers. LÄS MER

  4. 4. Macrophages, Nitric oxide synthases and Heme oxygenases: possible roles during peripheral nerve regeneration

    Författare :Sofia Magnusson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; satellite cells; peripheral ganglia; cell signalling; nerve regeneration; heme oxygenase; Macrophages; nitric oxide synthase; Animal physiology; Djurfysiologi;

    Sammanfattning : The purpose of this study was to investigate the suggestions that macrophages, and the systems generating nitric oxide (NO) and carbon monoxide (CO), i.e. nitric oxide synthases (NOS) and heme oxygenases (HO), could be important for peripheral nerve regeneration. LÄS MER
