  1. 21. Induced Growth and Precocious Maturation of the Digestive System in Suckling Rats and Pigs after Exposure to Red Kidney Bean Lectin

    Författare :Ann Linderoth; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neuropsykologi; neurofysiologi; Neurologi; neurophysiology; neuropsychology; Neurology; Fysiologi; Physiology; Djurfysiologi; Animal physiology; sucrase; lactase; amylase; trypsin; weaning; small intestine; glucocorticoids; endocytosis; dissacchridases; intestinal permeability; PHA; pancreas; Development; phytohaemagglutinin;

    Sammanfattning : The timing of the postnatal development of the gastrointestinal (GI) tract in mammals is influenced by dietary and hormonal factors. It was hypothesized that accelerated GI cell turnover during maturation would result in a precoucios conversion to more mature digestive functions. LÄS MER

  3. 22. Naturally derived cell-penetrating peptides and applications in gene regulation : A study on internalization mechanisms and endosomal escape

    Författare :Pontus Lundberg; Ülo Langel; Bernard Lebleu; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peptide; oligonucleotide; endocytosis; gene regulation; Neurochemistry; Neurokemi;

    Sammanfattning : Cell-penetrating peptides are a class of peptides which have achieved a lot of recognition due to their vector abilities. Since their discovery over a decade ago, there has been an uncertainty concerning the mechanism by which they are internalized into the cells. LÄS MER

  5. 24. Developmental and methodological aspects of intestinal and pancreatic function in pigs and rats

    Författare :Klas Rådberg; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; macromolecule; endocytosis; FITC-dextran; secretion; mucosa; CCK; pancreas; disaccharidase; intestinal permeability; lectin; morphometry; Animal physiology; Djurfysiologi;

    Sammanfattning : The gastrointestinal tract has two opposing functions; to effectively absorb nutrients and to act as a safety barrier against hazardous substances in the environment. After birth these functions develops gradually. LÄS MER

  7. 25. Cellular interactions of HAMLET and their role in cell death

    Författare :Maria Trulsson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HAMLET; alpha-lactalbumin; cancer; cell death; ion channels; p38; cell detachment; alpha-actinin; endocytosis; macropinocytosis; c-Myc; glycolysis;

    Sammanfattning : HAMLET is a protein-lipid complex that selectively kills tumor cells. In this thesis, we identified new mechanisms, whereby HAMLET initiates and executes tumor cell death. HAMLET targets several cellular compartments ranging from the plasma membrane to the nucleus. LÄS MER
