  2. 1. Neuroendocrine tumors of the digestive system : Modulation of apoptosis and factors associated with growth regulation during biotherapies

    Author : S. A. Hassan Imam; Uppsala universitet; []
    Keywords : Medical sciences; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Abstract : Neuroendocrine tumors of the gut have the potential to create life-threatening syndromes which become difficult to treat. Tumor mass reduction, by medical therapy, is one of the choices of treatments. READ MORE

  5. 3. Impact of the gut microflora on the digestive system in the suckling rat

    Author : Frida Fåk; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; probiotics; prebiotics; antibiotics; lactobacilli; bacteria; intestinal permeability; Small intestine; maturation; weaning; suckling;

    Abstract : The postnatal development of the gastrointestinal (GI) system in mammals is genetically programmed, but is, to an unknown extent, regulated by external factors such as the diet and the gut microflora. These factors can influence the growth of the GI tract, the age-related pattern of appearance of digestive enzymes and the decreased intestinal macromolecular permeability at gut closure, normally timed with weaning in young rodents.

  6. 4. Involvement of the immune system in phytohaemagglutinin-induced structural and functional precocious maturation of the gut in young rats

    Author : Olena Prykhodko; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytokines; mucosa; development; Gastrointestinal tract; mammals; immune system; T-cells;

    Abstract : Mammals are born with an immature gastrointestinal (GI) tract that allows the uptake of the specific nutrients and bioactive macromolecules in the milk, especially the protecting maternal antibodies. Eventually during weaning, the intake of milk decreases while that of solid food increases, and the GI system undergoes prominent structural and functional changes adapting the young this dietary change.

  7. 5. Interferon-alpha signaling and cell cycle regulation in neuroendocrine tumors of the digestive system

    Author : Yinghua Zhou; Uppsala universitet; []
    Keywords : Medical sciences; interferon-α; carcinoid tumors; interferon regulatory factor; p68; PKR; p21; p27; cell cycle; cyclin-dependent kinase; protein phosphorylation; protein trafficking; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Abstract : The prognosis for untreated carcinoid patients is poor and their quality of life is low. IFN-α treatment has shown a response rate of 50-80%, however, the antitumor mechanism has not been elucidated. READ MORE
