1. New Approaches to Studies of Paracellular Drug Transport in Intestinal Epithelial Cell Monolayers
Abstract : Studies of intestinal drug permeability have traditionally been performed in the colon-derived Caco-2 cell model. However, the permeability of these cell monolayers resembles that of the colon rather than that of the small intestine, which is the major site of drug absorption following oral administration.

2. Intestinal absorption of drugs : The impact of regional permeability, nanoparticles, and absorption-modifying excipients
Abstract : For successful delivery of orally given drug products, the drug compounds must have adequate solubility and permeability in the human gastrointestinal tract. The permeability of a compound is determined by its size and lipophilicity, and is usually evaluated in various pre-clinical models, including rat models. READ MORE

3. Epithelial barrier dysfunction in ileal Crohn's disease
Abstract : The study aimed at investigating the intestinal barrier in Crohn's disease, with special reference to epithelial responses to luminal stimuli, and to permeation of proteins.Ileal mucosa from patients undergoing intestinal resection was studied in vitro in Ussing chambers. READ MORE

4. Neural control of colonic epithelial transport, motility and permeability in vivo. An experimental study in anaesthetized rats
Abstract : Colonic dysfunction may result in diarrhoea, abdominal pain or constipation, andinflammatory bowel disease, bile acid malabsorption and particularly irritable bowelsyndrome are very common disorders. The role of the enteric nervous system (ENS) inthese diseases is largely unknown. READ MORE

5. Biopharmaceutical aspects of intestinal drug absorption : Regional permeability and absorption-modifying excipients
Abstract : Before an orally administered drug reaches the systemic circulation, it has to dissolve in the intestinal fluids, permeate across the intestinal epithelial cell barrier, and pass through the liver. The permeation rate of drug compounds can be low and show regional differences.The thesis had two general aims. READ MORE
