1. 6. Spleno-pancreatic development assessed by 3D molecular imaging

   Författare :Amir Asayesh; Ulf Ahlgren; Beatriz Sosa-Pineda; Umeå universitet; []
   Nyckelord :Cell biology; Spleen; Pancreas; Imaging; Development; Cellbiologi; miljömedicinsk utvecklingsbiologi; Developmental Biology;

   Sammanfattning : The development of different organs and tissues along the gastrointestinal tract, including the pancreas, depends on signalling between the endoderm and the adjacent mesenchyme. The Nkx gene Bapx1 is involved in spatial control of organ-positioning in the spleno-pancreatic region, and deficiency in this gene results in unacceptable proximity of the splenic mesenchyme to the pancreas.

   Sammanfattning : The studies presented here evaluate the biliary, parenchymal and vascular enhancement effects of two T1-shortening liver-specific contrast agents, Gd-BOPTA and Gd-EOB-DTPA, in Magnetic Resonance Imaging (MRI) of healthy subjects and of patients.Ten healthy volunteers were examined with both contrast agents in a 1.

5. 9. Clinical and experimental studies in Philadelphia chromosome negative chronic myeloproliferative disorders

   Författare :Peter Johansson; Göteborgs universitet; []
   Nyckelord :myeloproliferative disorders; polycythaemia vera; essential thrombocythaemia; epidemiology; erythropoietin; red-cell mass; spleen size; thrombo-embolic; PRV-1.;

   Sammanfattning : The present thesis deals with various aspects on the (a) epidemiology, (b) diagnosis, and (c) molecular biology in Philadelphia chromosome negative (Ph-) chronic myeloproliferative disorders (MPD). First, the incidence of the three Ph- MPD, polycythaemia vera (PV), essential thrombocythaemia (ET) and idiopathic myelofibrosis (IMF) was investigated in the city of Göteborg, Sweden during the years 1983-1999 (Paper I).

   Sammanfattning : The mouse pancreas is a mixed exocrine and endocrine glandconsisting of three lobular compartments: the splenic, duodenal and gastric lobes. During embryogenesis, the pancreas forms from two progenitor populations located on the dorsal and ventral side of the primitive gut tube. LÄS MER
