  1. 1. Contact activation on bacterial surfaces - a virulence mechanism

    Författare :Kristin Persson; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General biomedical sciences; Biomedicinska vetenskaper allmänt ; sepsis; infection; S. aureus; S. typhimurium; E. coli; curli; fibrinopeptides; fibrinogen; Coagulation; contact system;

    Sammanfattning : Life-threatening conditions from bacterial infections are a major clinical problem. During a severe infection, the host responds by a massive release of pro-inflammatory mediators together with a systemic activation of systems such as the coagulation, fibrinolytic, and complement systems.

  2. 2. Electronic Control of Cell Cultures Using Conjugated Polymer Surfaces

    Författare :Kristin Persson; Magnus Berggren; Edwin Jager; Peter Konradsson; Mihai Irimia-Vladu; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : In the field of bioelectronics various electronic materials and devices are used in combination with biological systems in order to create novel applications within cell biology and medicine. A famous example of a successful bioelectronics application is the pacemaker. LÄS MER

  3. 3. Radome Diagnostics: utilizing Source Reconstruction based on Surface Integral Representations

    Författare :Kristin Persson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nondestructive testing; source reconstruction; diagnostics; radome; phase reconstruction; insertion phase delay IPD ; equivalent surface currents;

    Sammanfattning : In this thesis, an inverse source reconstruction method with great potential in radome diagnostics is presented. A radome is a cover that encloses an antenna in order to protect it from environmental influences. LÄS MER

  4. 4. Retrieval of equivalent currents by the use of an integral representation and the extinction theorem --- radome applications

    Författare :Kristin Persson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extinction theorem; inverse source problem; integral representation; radome diagnosis; near-field transformation;

    Sammanfattning : The aim of this thesis is to solve an inverse source problem. The approach is based on an integral representation together with the extinction theorem. Both a scalar and a full-wave integral representation are implemented and solved by a Method of Moment procedure. LÄS MER

  5. 5. The neuropeptides GRP and PACAP and the function of the endocrine pancreas - A study on receptor deficient mice

    Författare :Kristin Persson; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; hypoglycemia; glucagon; insulin; islet of Langerhans; diabetes; PACAP; neuropeptides; GRP; diabetologi;

    Sammanfattning : The parasympathetic nerves are important for the regulation of insulin secretion, in particular after meal intake. Apart from acetylcholine, several neuropeptides can be found in the parasympathetic nerves innervating the islets of Langerhans, including gastrin-releasing peptide (GRP) and pituitary adenylate cyclase activating polypeptide (PACAP).
