1. 1. The hyperosmolar airway : Mechanisms of reduced response to nitric oxide

   Författare :Josephine Hjoberg; Uppsala universitet; []
   Nyckelord :Medical sciences; 8-Br-cyclic GMP; airway epithelium; airway reactivity; airway smooth muscle; amiloride; epithelium derived relaxing factor; furosemide; hyperosmolarity; hypertonic saline; nitric oxide; SNAP; sodium chloride; sodium nitroprusside; superoxide; tracheal perfusion; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

   Sammanfattning : Inhaled nitric oxide (NO) relaxes smooth muscle of the airways and of pulmonary blood vessels and is used to treat lung diseases where the pulmonary vessels are constricted. NO has also been tested as a bronchodilator in asthmatic patients. LÄS MER

3. 2. Allergic airway disease : studies on diesel exhaust exposures, oxylipins and antioxidants

   Författare :Nirina Larsson; Annelie Behndig; Leif Bjermer; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Asthma; allergic rhinits; diesel exhaust; airway inflammation; oxylipins; metabolomics; antioxidants; SVCT2; bronchoscopy; lungmedicin; Lung Medicine;

   Sammanfattning : Allergic airway disease, i.e. allergic rhinitis (AR) and asthma, is a common health problem. The prevalence is increasing in most countries of the world. LÄS MER

4. 3. Nitric oxide within the concept of united airway disease : Exhaled and nasal nitric oxide in cystic fibrosis, asthma and upper airway inflammatory diseases

   Författare :Christina Krantz; Andrei Malinovschi; Kjell Alving; Celeste Porsbjerg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nitric oxide; nasal NO; exhaled NO; asthma; cystic fibrosis; airway inflammation; upper airway inflammatory disorders; united airway disease; IgE sensitisation; Lungmedicin; Lung Medicine; Pediatrik; Pediatrics;

   Sammanfattning : Background: Within the concept of united airway disease, it is postulated that inflammatory disorders in the upper and lower airways are interrelated and influence each other. Fractional exhaled nitric oxide (FeNO) is an established biomarker of type-2 inflammation in the lower airways and is elevated in patients with asthma. LÄS MER

5. 4. Airway responsiveness and exhaled nitric oxide : Studies in asthma and Sjögren's syndrome

   Författare :Dóra Lúðvíksdóttir; Uppsala universitet; []
   Nyckelord :Medical sciences; Airway hyperresponsiveness; nitric oxide; airway inflammation; Sjögren s syndrome; asthma; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

   Sammanfattning : In this thesis, four different types of provocation agents: methacholine, adenosine, cold air and mannitol were used to study different aspects of the airway responsiveness profile in asthma and Sjögren's syndrome. Exhaled nitric oxide (NO) and markers of eosinophil activation, serum eosinophil peroxidase (S-EPO) and eosinophil cationic protein (S-ECP) were measured. LÄS MER

7. 5. Platelets and airway remodeling : Mechanisms involved in platelet-induced fibroblast and airway smooth muscle cell proliferation in vitro

   Författare :Ann-Charlotte B. Svensson Holm; Torbjörn Bengtsson; Eva Lindström; Mikael Adner; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Airway remodeling is a contributing cause to the pathological structural changes, such as increased cell proliferation, observed in asthma. Platelets have been found in autopsy lungmaterial obtained from asthmatic patients and are well known to induce proliferation in vitro of a variety of cells. LÄS MER
