  1. 11. Effects of Inflammatory Mediators on Pulmonary Airways

    Författare :Ofir Bachar; Klinisk och experimentell allergiforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electric ?eld stimulation; bradykinin; airway; tumor necrosis factor a; Respiratory system; nitric oxide; Andningsorganen; Toll-like receptor; prostaglandin E2; neurotrophin; allergy;

    Sammanfattning : Chronic inflammation is together with excessive contraction of the airways key features of asthma. The aims of the thesis were to analyze the effect of inflammatory mediators on airway smooth muscle, using an in vitro model of cultured murine airways. LÄS MER

  3. 12. SBRT of large tumors and tumors located near organs at risk in the thoracic cavity

    Författare :Vitali Grozman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Stereotactic Body Radiotherapy (SBRT) is a non-invasive ablative radiation therapy developed at Karolinska University Hospital in the early 90-s. Its basic principles are highly focused inhomogeneous dose load with rapid fall of in the periphery of the target, delivered in few fractions with high-doses per fraction. LÄS MER

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

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

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

  5. 14. Prostaglandin E2 as mediator and modulator of airway smooth muscle responses

    Författare :Jesper Säfholm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Prostaglandin E2 (PGE2) is a lipid mediator produced by virtually every cell of the human body. Because common non-steroidal anti-inflammatory drugs (NSAIDs) inhibit its biosynthesis, PGE2 is usually considered to be a ‘pro-inflammatory’ mediator. The role of PGE2 in the lung and airways has however always been unclear. LÄS MER

  7. 15. Defining the role of mast cells in guinea pig models of asthma

    Författare :Jielu Liu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Asthma is a common respiratory disease characterized by several pathophysiological features, such as allergen induced bronchoconstriction (in allergic asthma), airway hyperresponsiveness (AHR), airway inflammation, airway remodeling and mast cell hyperplasia. An increase of mast cells has been found in asthma patients. LÄS MER
