  2. 11. Studies of the ABO and FORS Histo-Blood Group Systems: Focus on Flow Cytometric and Genetic Analysis

    Author : Annika Hult; Avdelningen för hematologi och transfusionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood Group; ABO; Weak expression; FORS; Flow cytometry;

    Abstract : ABO is the clinically most important blood group system and its antigens are carbohydrate moieties present on the surface of the red blood cell (RBC) but also on other tissues throughout the body. The ABO gene encodes an enzyme, a glycosyltransferase (GT),that adds a terminal monosaccharide to the precursor structure, H antigen, to define the A or B antigens. READ MORE

  4. 12. Tissue Blood Flow Responses to External Pressure Using LDF and PPG : Testing a System Developed for Pressure Ulcer Research

    Author : Sara Bergstrand; Anna-Christina Ek; Margareta Lindgren; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Background: Pressure ulcers are a problem for immobile individuals, and having pressure ulcers impact and restrict the daily and are often associated with pain. Pressure ulcers occur frequently and cause high costs for the health care system. READ MORE

  5. 13. On macrophage contributions to tissue homeostasis : New insights on pancreas development and healing of ischemic injury

    Author : Carmen Herrera Hidalgo; Mia Phillipson; Andrés Hidalgo; Uppsala universitet; []
    Keywords : macrophages; islets of Langerhans; β cell function; postnatal β cell maturation; hindlimb ischemia; blood flow regulation; mural cells; vessel pruning; diabetes mellitus; ischemic diseases;

    Abstract : Besides providing host defence against innumerable threats, macrophages display additional key functions for preservation of tissue homeostasis. This thesis includes four studies that explore novel macrophage functions in both the development of islets of Langerhans and healing of ischemic injury in mice. READ MORE

  6. 14. Preventing pressure ulcers by assessment of the microcirculation in tissue exposed to pressure

    Author : Sara Bergstrand; Margareta Lindgren; Anna-Christina Ek; Maria Engström; Lars-Göran Lindberg; Fredrik Huss; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pressure ulcer; photoplethysmography; laser Doppler flowmetry; non-invasive; tissue blood flow; reactive hyperemia; pressure-induced vasodilation; interface pressure; risk assessment;

    Abstract : The overall aim of this thesis was to combine optical methods into a system with the ability to simultaneously measure blood flow changes at different tissue depths. The goal of such a system was to reveal vascular mechanisms relevant to pressure ulcer etiology under clinically relevant conditions and in relation to the evaluation of pressure-redistribution support surfaces.

  7. 15. On the Autonomic Control of Blood Flow and Secretion in Salivary Glands. Functional and morphological aspects on muscarinic receptor subtypes in different species

    Author : Anders Ryberg; Göteborgs universitet; []
    Keywords : Muscarinic receptor subtype; neuronal; non-neuronal; expression; secretion; blood flow; salivary gland; human; rat; sheep;

    Abstract : Parasympathetic nervous activity is the principal stimulus for evoking fluid responses within salivary glands. Concomitantly to the onset of this response, the blood flow increases. READ MORE
