1. 16. Apoptosis in chronic inflammation, with specific reference to airway disease

   Författare :Malin Müller; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Apoptosis; asthma; chronic inflammation; lung; sarcoidosis; tributyltin TBT ;

   Sammanfattning : Mechanisms governing the normal resolution processes of inflammation in the lung are poorly understood, yet their elucidation may lead to a greater understanding of the pathogenesis of several pulmonary inflammatory disorders. The elimination of activated lymphocytes by apoptosis is one prerequisite for resolution, and knowledge concerning the role of apoptosis in chronic inflammation is still far from complete. LÄS MER

3. 17. Lung mechanics in the aging lung and in acute lung injury. Studies based on sinusoidal flow modulation

   Författare :Ulrika Bitzén; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diagnostics; Diagnostik; acute lung injury; lung mechanics; acute respiratory distress syndrome; intensivvård; Anestesiologi; intensive care; Anaesthesiology; Andningsorganen; Respiratory system; Fysiologi; Physiology; flow regulation; method; lung resistance; compliance; aging;

   Sammanfattning : Knowledge about lung mechanics is of interest in intensive care to adjust mechanical ventilation and in the lung laboratory for diagnostics and evaluation of patients with various kinds of respiratory diseases. In mechanical ventilation a single inspiratory elastic pressure-volume (Pel/V) curve is difficult to interpret due to continuing re-expansion of collapsed lung units over a large pressure interval.

4. 18. FRC in acute lung injury. Experimental and clinical studies

   Författare :Christian Rylander; Göteborgs universitet; []
   Nyckelord :Airway obstruction; Acute lung injury; Acute respiratory distress syndrome; Attenuation; Computed tomography; End-expiratory lung volume; Functional residual capacity; Gas dilution; Hounsfield unit; Lung volume; Oleic acid; Recruitment; Time constant;

   Sammanfattning : Respiratory failure due to acute lung injury (ALI) of diffuse inflammatory origin is a major cause of respiratory failure treated in intensive care units. In ALI, FRC is reduced by various mechanisms associated with hypoxemia and consolidation of the lung. LÄS MER

5. 19. Deposition and clearance of inhaled particles in patients with obstructive airway diseases

   Författare :Katharina Svartengren; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :bronchial asthma; chronic bronchitis; immotile-cilia syndrome; tracheobronchial clearance; mucus; cough; particle deposition; laryngoscopy; lung function;

   Sammanfattning : A large part of the population (at least 10%) suffers from asthma or chronic bronchitis. Knowledge of deposition and clearance of inhaled particles in the respiratory tract in this group of patients is essential for estimating environmental health hazards, as well as optimal effects of therapeutic aerosols.

7. 20. Distribution and Effects of NO and CO in the Human Upper Respiratory Tract

   Författare :Jens Andersson; Helsingborg Kliniska Vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; transplantation; Microbiology; bacteriology; virology; serologi; Immunologi; serology; Otorhinolaryngology; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen; Immunology; sinus; upper respiratory tract infection; nose; nitric oxide; neutrophil migration; middle ear; hemin; flow cytometry; allergy; carbon monoxide;

   Sammanfattning : Mucosal inflammation and airway hyperreactivity are regulated by hundreds of different mediators. The recent discovery of gaseous mediators, produced and active within the airways, opens new possibilities for identification of therapeutic targets and ways to monitor airway inflammation. LÄS MER
