  1. 6. Mechanisms for and Effects of Airway Epithelial Damage in Asthma

    Författare :Anne-Jacqueline Relova; Eythor Björnsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; asthma; airways; cytokines; epithelium; tight junctions; mast cells; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : The airway epithelium plays a crucial role in protecting the underlying connective tissue (CT) from noxious agents. Damage and shedding of the epithelium are observed in the airways of asthma, cystic fibrosis and rhinitis patients. LÄS MER

  3. 7. Blue light induced retinal damage

    Författare :Jiangmei Wu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Visual perception results from a response to radiation between 400 and 760 mu reaching the retina. Photoreceptor cells are differentiated post-mitotic retinal neurons uniquely adapted for the efficient capture of photons and for the initiation of visual transduction. LÄS MER

  4. 8. Structure and dynamics of epithelial cells : Studied with confocal microscopy and flourescence recovery after photobleaching

    Författare :Kajsa Holmgren-Peterson; Annika Scheynius; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Epithelial cells of the human body form a physical barrier to harmful agents and potential invading microorganisms. In the small intestine they must also produce enzymes for digestion of food and be able to absorb nutrients. LÄS MER

  5. 9. Role of alveolar epithelial cells in macrophage responses against mycobacterial infections

    Författare :Olga Daniela Chuquimia Flores; Carmen Fernández; Diana Boraschi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lung; alveolar epithelial cells; macrophages; AEC-derived media; control of intracellular bacterial growth; mycobacterial infections; immunologi; Immunology;

    Sammanfattning : This thesis aimed to investigate the role of alveolar epithelial cells (AEC) on immune responses against mycobacterial infections, specifically, the role of AEC in modulating macrophage functions through the secretion of broad variety of factors.In paper I, we compared murine AEC with interstitial macrophages (PuM) in their ability to take up and control mycobacterial growth and their capacity as antigen-presenting cells.

  7. 10. Flexible fiberoptic bronchoscopy : studies on methods for the diagnosis of carcinoma of the lung, bronchial mucosal damage and haemodynamic effects

    Författare :Rune Lundgren; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Flexible fiberoptic bronchoscopy; bronchial carcinoma; brush biopsy; respiratory mucosal damage; regeneration; mucociliary clearance; haemodynamic effects; hypoxemia;

    Sammanfattning : The diagnostic accuracy attained with the use of transbronchial fine needle aspiration biopsy, aspiration of bronchial secretion, bronchial washing, brush biopsy and forceps biopsy via a flexible fiberoptic bronchoscope was compared in patients with carcinoma of the lung. In endoscopic visible tumours the sensitivity of forceps biopsy was higher than that of the other methods. LÄS MER
