  1. 6. Exhaled nitric oxide in extreme environments

    Författare :Tryggve Hemmingsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Exhaled nitric oxide; hand-held instrument; electrochemical detector; microgravity; International Space Station; high altitude; hypobaric hypoxia; normobaric hypoxia; backdiffusion;

    Sammanfattning : Exhaled nitric oxide (NO) is a useful marker for lower airway inflammation. Since NO was found to be a component of an exhaled breath in the early 1990´s, the Fractional Exhaled Nitric Oxide (FENO 50) measurement is now well accepted among clinicians as a complementary test in the management of asthma.

  3. 7. Nitric oxide in experimental pulmonary embolism

    Författare :Kristofer F Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Nitric oxide (NO) is an important modulator of the pulmonary circulation both at basal state and in pulmonary hypertension. Low levels of NO are detectable in exhaled gas which is believed to mirror pulmonary NO formation and elimination. LÄS MER

  4. 8. Extracellular Matrix Alterations in Patients with Different Phenotypes of Asthma

    Författare :Maria Weitoft; Lungbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Asthma; Extraceullar matrix; Proteoglycan; Collagen; Hyaluronan; Fibrocyte; Mast cell; Nitric oxide;

    Sammanfattning : AbstractAsthma is a chronic disease that affects approximately 300 million people worldwide, and the prevalence is increasing. It has become clear that asthma is a highly heterogeneous disease, with overlapping symptoms but with diverse immunopathology and clinical phenotypes. LÄS MER

  5. 9. Remote Ischemic Preconditioning and its Effects on the Respiratory System

    Författare :Astrid Bergmann; Anders Larsson; Göran Hedenstierna; Thomas Hachenberg; Ola Winsö; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; one-lung ventilation; ventilation-induced lung injury; alveolar immune response; remote ischemic preconditioning; exhaled nitric oxide; animal model; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : Mechanical ventilation in itself can lead to pulmonary damage, and one-lung ventilation (OLV), necessary for thoracic surgery, accentuates this injury. Remote ischemic preconditioning (RIP) is a potential tool to reduce lung injury after mechanical ventilation, including OLV.  However, current data on pulmonary RIP-effects are contradictory.

  7. 10. Exploring small airways using breath analyses

    Författare :Emilia Viklund; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; exhaled particles; small airways; alveolar nitric oxide; SARS-CoV-2; birch pollen; smoking; lining fluid;

    Sammanfattning : Background: Airway irritants such as allergens, tobacco smoke and viruses may cause damage in the small airways, usually undetected with routine diagnostic methods. Analyses of endogenously produced nitric oxide (NO) and endogenously produced small droplets (i.e. LÄS MER
