  1. 1. Intestinal Bypass and Total Parenteral Nutrition: Changes in Gut Function and Morphology

    Författare :Mikael Ekelund; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Kirurgi; ortopedi; traumatologi; orthopaedics; Surgery; Gastroenterologi; Gastro-enterology; Fysiologi; Physiology; total parenteral nutrition; supersensitivity; plasticity; intestinal bypass; interstitial cells of Cajal; goblet cells; eosinophils; adaptation; enteric nervous system;

    Sammanfattning : Abolition of enteral nutrition is sometimes required in severe illness. The primary aim of the present work has been to elucidate possible changes in intestinal morphology and motor function in absence of enteral nutrition. Total absence of enteral nutrition in an isolated intestinal segment was created by bypassing the distal ileum in a rat model. LÄS MER

  3. 2. Pathophysiology and treatment of defective insulin secretion in diabetes

    Författare :Anders Rosengren; Diabetes - öpatofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pancreatic beta-cells; stem cells; genetics; exocytosis; Adra2a; PACAP; GLP-1; Physiology; Fysiologi; secreting systems; Endocrinology; diabetology; Endokrinologi; insulin secretion; Diabetes mellitus; sekretion; diabetologi;

    Sammanfattning : Defective insulin secretion is a central feature in diabetes mellitus and results from reduced pancreatic beta-cell mass as well as aberrant beta-cell function. The pathophysiology of diabetes is incompletely known, but a strong hereditary component is suggested. LÄS MER

  4. 3. Radiotherapy Gel Dosimetry: Development and Application of Normoxic Polymer Gels

    Författare :Helen Gustafsson; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; tomografi; medicinsk instrumentering; Radiofarmaceutisk teknik; Radiopharmaceutical technology; proton; LET; FT Raman spectroscopy; MRI; normoxic gel; IMRT; 3D verification; polymer gel dosimetry; radiologi;

    Sammanfattning : In many radiotherapy applications, true three-dimensional dosimetry with good spatial resolution that can be achieved in a single measurement would be of great value. Polymer gel dosimetry fulfils many of the demands on such a system. In this study, methods to facilitate the implementation of gel dosimetry have been investigated. LÄS MER

  5. 4. On urbanisation and birds : Insights from a molecular and physiological perspective

    Författare :Pablo Salmon; Evolutionär ekologi; []
    Nyckelord :Air Pollution; Antioxidants; Birds; great tit Parus major; Local adaptation; Nitrogen oxides; Oxidative stress; Parallel evolution; Survival; Telomere dynamics; Telomeres; Urbanisation;

    Sammanfattning : Urbanisation of natural habitats is rapidly intensifying and poses a potential global threat for wildlife. Thus, it is important to explore its impact on wildlife in order to understand the present and future threats and how resilient organisms are to them. LÄS MER
