  1. 16. Functional analysis of Ipf1/Pdx1, MFng and Id during pancreatic growth and differentiation

    Författare :Per Svensson; Helena Edlund; Henrik Semb; Umeå universitet; []
    Nyckelord :pancreas; proliferation; differentiation; signalling; expression; FgfR2IIIb; ErbB3; spondin1; MFng; Id; molekylär medicin genetik och patologi ; molecular medicine  genetics and pathology ;

    Sammanfattning : The pancreas is an endodermally derived organ consisting of three major cell lineages. The endocrine cells, organised into the Islets of Langerhans, regulate blood glucose homeostasis by producing and secreting hormones such as glucagon and insulin into the bloodstream. LÄS MER

  3. 17. Optical projection tomography based 3D-spatial and quantitative assessments of the diabetic pancreas

    Författare :Tomas Alanentalo; Ulf Ahlgren; Raphael Scharfmann; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nkx; development; optical projection tomography; 3D visualisation; pancreas; beta-cell mass; insulitis; diabetes; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : The gastrointestinal tract comprises a number of digestive organs including the stomach and pancreas. The stomach is involved in the digestion and short term storage of food while the pancreas is a mixed endocrine and exocrine gland which provides the body with hormones and enzymes essential for nutritional utilisation.

  4. 18. Regulation of the exocrine pancreas in growing pigs, with special emphasis on entero-pancreatic reflexes

    Författare :Lena Evilevitch; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kidney bean lectin; Animal physiology; Djurfysiologi; duodenum; entero-pancreatic reflex; insulin; lipas; amylas; trypsin; weaning; development; maturation; inhibition; CCK-receptors; Exocrine pancreas; CCK; pig;

    Sammanfattning : The regulation of the exocrine pancreas has been under thorough investigation for many decades. In rats, cholecystokinin (CCK) is considered to be the major gut hormone stimulating the pancreas to releasing the digestive enzymes. LÄS MER

  5. 19. Isoprenylation and NET formation in acute pancreatitis

    Författare :Mohammed Merza; Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute pancreatitis; neutrophil recruitment; trypsinogen activation; NET;

    Sammanfattning : Acute Pancreatitis (AP) is an inflammation disease that characterized by activation of protease and the innate immune system, leading to infiltration of neutrophils and tissue damage in the pancreas. The aim of this thesis was to determine the role of isoprenylation (farnesyltransferase and geranylgeranyltransferase) as well as NET formation in regulating recruitment of neutrophils and tissue damage in severe AP.

  7. 20. Modulation of serous salivary gland function by the sympathetic nervous system : a biochemical and ultrastructural study with special reference to β-adrenoceptor subtypes

    Författare :Roger Henriksson; Umeå universitet; []
    Nyckelord :Rat parotid gland; guinea-pig submandibular gland; ß-adrenoceptor subtypes; sympathetic denervation; sympathetic superstimulation; amylase secretion; cyclic AMP; ultrastructural stereology;

    Sammanfattning : The aim of the present investigation was to study the influence of the sympathetic nervous system and of various adrenoceptor agents on enzyme secretion and morphology in rat parotid and guinea-pig submandibular glands. Biochemical methods were combined with electron microscopical techniques. LÄS MER
