  2. 1. A Surface Phase Model of the Alveolar Lining: Ultrastructural Analysis and in vivo Applications

    Author : Marcus Larsson; Lund Pediatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; X-ray diffraction; cryo-TEM; dynamic swelling; ARDS; surface phase; surfactant replacement therapy; cholesterol; minimal surface; pulmonary surfactant; alveolar surface; Physiology; Fysiologi;

    Abstract : In this thesis the relation between lung surfactant structure and functional properties have been studied. Experimental results show that the alveolar surface is formed by a coherent surface phase with a structure equal to tubular myelin. The properties of this phase may explain certain unresolved issues in lung physiology, e.g. READ MORE

  4. 2. Microfabrication for Biological Applications. Preparation, Characterization and Biological Evaluation

    Author : Julie Gold; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asbestos; surface spectroscopy; lithography; microfabrication; fibers; surface modification; biomaterials;

    Abstract : Foreign materials are intentionally placed into patients in the form of medical devices for replacing or repairing damaged portions of the body. Materials also enter the body unintentionally in the form of particulates and fibers, and can then have damaging effects, such as the formation of disease or even cancer. READ MORE

  5. 3. Phagolysosomal pH measurements in alveolar macrophages

    Author : Kristina Nyberg Lindborg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : alveolar clearance; alveolar macrophages; phagocytosis; phagolysosomal pH; respiratory burst; silica particles; S. cerevisiae; C. albicans;

    Abstract : Background: Mechanical clearance of insoluble particles from the alveolar part of the lung is known to be a slow process in humans, i. e., one or several years. Particles deposited in the alveolar region are phagocytized by alveolar macrophages (AM). READ MORE

  6. 4. Bone tissue regeneration indento-alveolar surgery : clinical and experimental studies on biomaterials and bone graft substitutes

    Author : Annika Sahlin-Platt; Maria Ransjö; Christer Dahlin; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomaterials; bone graft substitutes; compomer; root end filling; Bio-Oss; Bioactive glass 45S5; Algipore; SEM EDAX; ICP-OES; Cryo-XPS;

    Abstract : Pathological processes in the alveolar and facial bones can lead to bone loss that may not heal with complete regeneration. Biomaterials can be used to facilitate the healing process and/or as a bone substitute, but the mechanisms are not fully understood. READ MORE

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

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

    Abstract : 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.
