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

    Author : Ann Linderoth; Biologiska institutionen; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Development of the gastrointestinal tract in young mammals : Effects of enteral provocation with protease or phytohaemagglutinin in neonatal rats

    Author : Ester Arevalo Sureda; Funktionell zoologi; []
    Keywords : gut; Intestine; Pancreas; development; precocious; protease; PHA; enterocytes; permeability; endocytosis; IgG; FcRn; Blimp1; T-lymphocyte; passive immunity; altricial; neonatal; suckling; athymic; rat; immunohistochemistry IHC ;

    Abstract : The rat, as an altritial species, is born with an immature gastrointestinal tract and intestinal barrier function, which is highly absorptive to milk-borne bioactive molecules that can pass undigested and reach the general circulation of the suckling newborn. This passage occurs by the neonatal-Fc-receptor (FcRn) binding and trancytosis of immunoglobulin G in the proximal small intestine (SI) and by the highly endocytic vacuolated enterocytes non-selectively in the distal SI.

  5. 3. 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.

  6. 4. Immunological factors in breast milk in relation to allergy in mother and child

    Author : Malin Fagerås-Böttcher; Erkki Savilahti; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Background: The allergy preventive effect of breast-feeding against the development of allergy is controversial and some of this controversy may be due to differences in the composition of breast milk between different mothers.Aim: To analyse IgA, cytokine and chemokines levels in human milk and relate the findings to matemal allergy and to development of atopic disease and IgA production in the infants, and furthermore, to assess the effects of breast milk on CBMC cytokine production.

  7. 5. T cell Function in Patients with Dilated Cardiomyopathy

    Author : Erika Lindberg; Göteborgs universitet; []
    Keywords : cardiomyopathy; lymphocytes; cytokines; autoimmunity; infection;

    Abstract : Dilated cardiomyopathy (DCM) is a heart muscle disease characterized by dilatation of one or both ventricles together with decreased systolic function. Its etiology is still largely unknown. READ MORE
