  1. 16. Nasal and bronchial airway reactivity in allergic and non allergic airway inflammation

    Författare :Karl-Gustav Kölbeck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Nasal hyperreactivity; airway hyperresponsiveness; Rhinostereometry; organic dust; adhesion molecules; endothelial cells;

    Sammanfattning : In allergic or asthmatic airways disease, upper and lower airways show a uniform eosinophilic inflammation of the mucosa, and bronchial hyperreactivity is a common finding. To study the co- variation of mucosal reactivity in upper and lower airways, histamine challenges of both sites were performed in a group of patients with allergic rhinitis during non-season.

  3. 17. Role of glycosylation in regulation of E-selectin expression on endothelial cells

    Författare :Jan Strindhall; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Endothelial cells located on the vessel walls play an important role in inflammation. In response to cytokines or other inflammatory mediators endothelial cells will express different cell adhesion molecules that are involved in binding of circulating leukocytes to the endothelium.

  4. 18. From the pancreatic beta cell to the endothelium:Pathophysiological aspects of Type 2 Diabetes

    Författare :Marloes Dekker Nitert; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sekretion; diabetologi; diabetology; insulin secretion; beta cells; glucose tolerance; insulin receptors; IGF-I receptors; endothelial cells; Endokrinologi; Type 2 Diabetes; secreting systems; Endocrinology;

    Sammanfattning : The incidence of Diabetes Mellitus increases globally in epidemic proportions. Type 2 Diabetes is the most prevalent form of Diabetes, comprising 90% of the patients. In Type 2 Diabetes, two processes contribute to the development of the disease: insufficient insulin secretion from the pancreatic ?-cell and insulin resistance of the target organs. LÄS MER

  5. 19. Vascular development and safeguard mechanisms against tumorigenesis : oncogene-induced apoptosis and cellular senescence

    Författare :Eduar Hejll; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Angiogenesis;

    Sammanfattning : Angiogenesis, apoptosis and senescence are all cellular processes that have an impact on tumor development. Angiogenesis or the new vessel formation from pre-existing ones is known to be required for invasive tumor growth and metastasis. LÄS MER

  7. 20. Rational design of nanoparticles for biomedical imaging and photovoltaic applications

    Författare :Haiyan Qin; Hans Ågren; Alexander Dmitriev; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; Teoretisk kemi;

    Sammanfattning : This thesis aims to rationally design nanoparticles and promote their applications in biomedical imaging and photovoltaic cells. Quantum dots (QDs) are promising fluorescent probes for biomedical imaging. LÄS MER
