  2. 21. Oropharyngeal origin of markers in exhaled breath

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

    Abstract : 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. READ MORE

  4. 22. The effects of posture, airway pressure and anesthesia on regulation of the regional ventilation and perfusion distribution in healthy humans

    Author : Sven Nyrén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Anesthesia; ALI; ARDS; CPAP; Dual isotope; Mechanical ventilation; Nitric oxide; Nuclear medicine; Prone position; Regional ventilation; Regional perfusion; SPECT;

    Abstract : Gas exchange has been observed to vary with posture in adult respiratory distress syndrome (ARDS) patients. In this thesis, the effect of posture on theregional distribution of ventilation (V) and perfusion (Q) in the lungs under normal breathing with and without continuous positive airway pressure (CPAP) and during general anesthesia with mechanical ventilation was studied.

  5. 23. Diesel exhaust and wood smoke : mechanisms, inflammation and intervention

    Author : Ala Muala; Thomas Sandström; Mark W Frampton; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Air pollution; deposition; bronchoscopy; Immunohistochemstry; filter; NO bioavailability; lungmedicin; Lung Medicine;

    Abstract : Background Particulate matter (PM) air pollution is associated with increased respiratory and cardiovascular morbidity and mortality. Diesel engine exhaust (DE) and wood combustion are major contributors to ambient air pollution and adverse health effects. READ MORE

  6. 24. Every breath you take every move you make. Studies on Asthma and Sports in Adolescent Athletes

    Author : Kerstin Romberg; allergologi och palliativ medicin Lungmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adolescence; asthma; airway hyper-reactivity; mannitol provocation; exercise challenge; CC16; gender; life style; quality of life;

    Abstract : Asthma and allergies are common diseases in adolescents and have increased during the last few decades. All elite level sports activities result in increased risk of asthma and rhinitis regardless of sport practised. READ MORE

  7. 25. Clinical studies on the role of eicosanoids in the asthmatic airway inflammation

    Author : Kameran Daham; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The underlying mechanisms in the asthmatic airway inflammation involve the interaction between different cells and mediators that consequently result in different clinical phenotypes. The aim of this thesis was to investigate the impact of inflammatory mediators, with emphasis on eicosanoids, on the inflammatory and functional airway responses under basal and triggered conditions in subjects with asthma, in particular ASA/NSAID-intolerant and allergic phenotypes.
