  2. 1. Studies on nitric oxide in the respiratory system

    Author : Ulla Schedin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : nitric oxide; endogenous; respiratory system; neonate; prematureinfant; animal; primate; elephant; chemiluminescence; electrochemical; nitrogen dioxide; trachea; nose; ;

    Abstract : Nitric oxide (NO) is formed in biological tissues and has regulatory functions in many organ systems. Endogenous NO has been found in exhaled air and NO is considered to have effects on the pulmonary circulation and bronchial tone, and to be one of the mediators for the circulatory adaptation at birth.

  4. 2. Tools for protective lung ventilation. The elastic pressure-volume curve and aspiration of dead space

    Author : Edoardo De Robertis; Lund Klinisk fysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; radiology; tomografi; medicinsk instrumentering; radiologi; Klinisk fysiologi; tomography; medical instrumentation; Respiratory system; Andningsorganen;

    Abstract : Ventilator-induced lung injury (VILI) may contribute to morbidity and mortality of acute lung injury (ALI). Lung protective ventilation (LPV), that reduces VILI, may involve low tidal volume (Vt). Particularly low Vt is possible if dead space ventilation is reduced e.g. READ MORE

  5. 3. Endothelin receptor changes during inflammation in the lung

    Author : Bengt Granström; Lund Pediatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Andningsorganen; Respiratory system; Upregulation; Smooth muscle cells; Smoking; Sephadex; Remodeling; Rat; mRNA; Human; ETB receptor; ETA receptor; Lung; Endothelin; Asthma bronchiale; Contraction;

    Abstract : Endothelin-1 (ET-1) is an extremely potent smooth muscle spasmogen well known from the vascular system but also active within the airways. The importance of its proinflammatory and co-mitogenic properties has become increasingly evident, the endothelin system also having been shown to mimic the signal features of asthma, COPD and other pulmonary diseases.

  6. 4. Genome-wide identification of Grainy head target genes and their functions in Drosophila embryos

    Author : Liqun Yao; Christos Samakovlis; Ruth Palmer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Grainy head; Stitcher; Vvl; wound healing; Tracheal development; Drosophila; utvecklingsbiologi; Developmental Biology;

    Abstract : The transcription factor Grainy head (Grh) is conserved from Drosophila to humans. Drosophila Grh plays important roles in epithelial differentiation and regeneration. READ MORE

  7. 5. Mucins in normal and diseased airways

    Author : Hans Hovenberg; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Respiratory system; Submucosal glands; Goblet cells; Organ culture; Respiratory tract; Mucins; Mucus glycoproteins; Andningsorganen;

    Abstract : Mucus glycoproteins (mucins) are the principal constituents of respiratory secretions in health and disease. The increased 'acidity' of mucin producing cells in the bronchitic airways is not reflected in a change of negative charge of bronchitic mucins. READ MORE
