  2. 1. Developmental and methodological aspects of intestinal and pancreatic function in pigs and rats

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

    Abstract : 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. READ MORE

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

    Author : Lena Evilevitch; Biologiska institutionen; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. 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

  6. 4. Studies on Peripheral Nerve Regeneration: Microdispensing, Neurite Guidance and Galectins

    Author : Per Gustavsson; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; vävnadskultur; histokemi; cytokemi; Histologi; tissue culture; histochemistry; cytochemistry; Histology; Schwann cells; sciatic nerve; dorsal root ganglia; DRG; neurite guidance; galectins; inkjet; microdispensing; peripheral nervous system; nerve regeneration; Animal physiology; Djurfysiologi; Biotechnology; Bioteknik;

    Abstract : The present thesis describes development of a microdispenser-based technique to create of protein patterns for neurite guidance. The same technique was also developed to allow direct positioning of dissociated cells, including neurons, on cell culture substrates. Finally the role of galectin-3 and 8 during nerve regeneration was investigated. READ MORE

  7. 5. Carbohydrate Synthesis and Study of Carbohydrate-Lectin Interactions Using QCM Biosensors and Microarray Technologies

    Author : Zhichao Pei; Olof Ramström; Roland J. Pieters; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lectins; Carbohydrates; Molecular recognition; Biosensors; Quartz crystal microbalance; Carbohydrate microarrays.; Organic chemistry; Organisk kemi;

    Abstract : Interactions between carbohydrates and proteins are increasingly being recognized as crucial in many biological processes, such as cellular adhesion and communication. In order to investigate the interactions of carbohydrates and proteins, the development of efficient analytic technologies, as well as novel strategies for the synthesis of carbohydrates, have to be explored.
