  1. 21. Nitric oxide and the lung : effects of spaceflight and hypergravity

    Författare :Lars Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Nitric oxide (NO) is an important signal molecule in the body, in particular in the cardiovascular system. This highly reactive molecule is difficult to detect in tissues, but in gas-filled cavities such as the airways it can be detected in part per billion amounts. LÄS MER

  3. 22. 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.

  4. 23. MEMS-based electrochemical gas sensors and wafer-level methods

    Författare :Hithesh K Gatty; Göran Stemme; Roxhed Niclas; Anita Lloyd Spetz; KTH; []
    Nyckelord :MEMS; gas sensors; electrochemical; nitric oxide; hydrogen sulphide; nafion; nano;

    Sammanfattning : This thesis describes novel microel ectromechanical system (MEMS) based electrochemical gas sensors and methods of fabrication.This thesis presents the research in two parts. In the first part, a method to handle a thin silicon wafer using an electrochemically active adhesive is described. LÄS MER

  5. 24. Optimizing and evaluation of a methacholine provocation test : with application in occupational research

    Författare :Britt-Marie Sundblad; Bengt-Eric Skoogh; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Airway responsiveness; methacholine provocation; nitric oxide; eucapnic hyperventilation; organic dust; Fysiologi; Physiology; Fysiologi; Physiology; fysiologi;

    Sammanfattning : We have developed a methacholine provocation method, which detects bronchial responsiveness in more than 80% of healthy subjects. The method enables us to detect differences in bronchial responsiveness within the normal range. With this method FEV1 and Gaw had similar sensitivity in detecting small differences in bronchial responsiveness. LÄS MER

  7. 25. 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
