2. 1. 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.

4. 2. Lactic acid bacteria fermentations in oat-based suspensions

   Author : Olof Mårtensson; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beta-glucans; probiotics; prebiotics; bacterial survival; Food and drink technology; Livsmedelsteknik; oats; ropiness; lactic acid bacteria; ropy;

   Abstract : This thesis deals with the fermentation characteristics of lactic acid bacteria (LAB) in oat-based suspensions, with formulation work of fermented products based on oat and with nutritional studies of these products. Changes in structure in terms of viscosity and ropiness were studied when exopolysaccharide (EPS)-producing LAB strains, namely, Lactobacillus delbrueckii subsp. READ MORE

5. 3. Influence of the microflora on gastrointestinal nitric oxide generation : studies in newborn infants and germ-free animals

   Author : Tanja Sobko; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Nitrite; nitrate; IBD; lactobacilli; probiotics; germ-free; SCFA; H 2; newborn infants;

   Abstract : Interactions between intestinal bacteria and the host play an important role in physiological regulation of gut function and in development of various diseases. Nitric oxide (NO) exhibits a variety of biological actions in the gut including regulation of regional blood flow, gut motility, water and electrolyte transport and immunity. READ MORE

6. 4. Influence of probiotics and other external factors on intestinal biochemical microflora-associated characteristics : studies in vitro and in vivo in gnotobiotic mice and in pigs

   Author : Maria E Cardona G; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Gastrointestinal microflora germ-free mice; lactic acid bacteria; microflora- associated characteristics; piglets; probiotics.;

   Abstract : The benefit of harboring a balanced intestinal microflora is well recognized. Therefore, in order to 'maintain or improve the intestinal flora, the use of microbial species as feed supplements, i.e. probiotics, has rapidly increased. READ MORE

7. 5. Intestinal cell kinetics : modulation caused by age, gender and microbial status in rats and mice : an experimental study in germfree, conventional, Lactobacillus rhamnosus GG and Clostridium difficile monoassociated animals

   Author : Mahnaz Banasaz; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Mammals living in symbiosis with microbes create conventional organisms. The interactions or cross-talks that continuously occur demonstrate how microbes may influence on series of parameters, including intestinal cell kinetics and mucosal morphology. READ MORE
