  1. 1. Analysis of Endogenous Particles in Exhaled Air

    Författare :Ann-Charlotte Almstrand; Göteborgs universitet; []
    Nyckelord :exhaled particles; time-of-flight secondary ion mass spectrometry; OPLS; airway closure; exhaled breath condensate; glutathione;

    Sammanfattning : Exhaled air contains non-volatile particulate material from the respiratory tract. The precise location in which exhaled particles are formed is unknown, and details on their chemical content are scarce. The aim of this work was to chemically characterize and to study the mechanisms of formation of endogenous particles in exhaled air. LÄS MER

  3. 2. Exhaled Breath Condensate in Obstructive Lung Diseases : A Methodological study

    Författare :Anette Davidsson; Birgitta Schmekel; Rolf Andersson; Sven‐Erik Dahlén; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Asthma and chronic obstructive pulmonary disease (COPD) are two common inflammatory airway diseases characterized by airway inflammation and mucus hypersecretion. Prediction of the outcome of these diseases may not be performed and the need for non-invasive diagnostic tools capable of identifying inflammation in asthma and COPD becomes therefore obvious.

  4. 3. Exhaled markers of oxidative stress in the airways

    Författare :Mona Lärstad; Göteborgs universitet; []
    Nyckelord :exhaled air; exhaled breath condensate; malondialdehyde; 3-nitrotyrosine; ethane; pentane; isoprene; oxidative stress; airways; inflammation;

    Sammanfattning : Breath contains a number of different molecules, some of which may have potential use as markers for oxidative stress in the airways during chronic airway inflammation. The major objectives were to develop and validate methods for quantifying five potential exhaled markers of oxidative stress: malondialdehyde (MDA) and free 3-nitrotyrosine (3-NT) in exhaled breath condensate (EBC) and ethane, pentane and isoprene in exhaled air, and to test the applicability of the methods.

  5. 4. Oropharyngeal origin of markers in exhaled breath

    Författare :Helena Marteus; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Exhaled nitric oxide; exhaled breath condensate; saliva; nitrite; nitrate; ammonia; pH; bacteria;

    Sammanfattning : Normal NO formation in the human airways occurs primarily in the nasal airways, where it is catalyzed by inducible NO synthase (iNOS), and in the oropharyngeal tract, via as yet not fully defined pathways. This NO can be detected in exhaled breath and when inflammation is present in the airways, for example in asthma, the concentration of NO is increased. LÄS MER

  7. 5. Exhaled nitrogen oxides and carbon monoxide in asthma and cystic fibrosis : markers of inflammation?

    Författare :Wilhelm Zetterquist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Exhaled markers of airway inflammation have attracted much interest as potential tools for monitoring the bronchial inflammation of respiratory disease. Exhaled nitric oxide (NO), its metabolites nitrite and nitrate in breath condensate (EBC), and exhaled carbon monoxide (CO), have been suggested for this purpose. LÄS MER
