16. Gut microbiota, its modifications and the gut-brain axis
Sammanfattning : The human intestinal microbiota has a major impact on host physiology and might play an important role in several diseases. Therapeutic interventions aimed at modifying the gut microbiota might exert their effects locally as well as systemically, for example via the gut-brain axis, a bidirectional communication system.

17. Microscopic colitis : epidemiology, death and associated disorders
Sammanfattning : Microscopic colitis (MC) is the most recently recognized inflammatory condition of the large intestine. MC is an umbrella term for two disease entities, namely lymphocytic colitis (LC) and collagenous colitis (CC). LÄS MER
18. Nitric oxide : a surrogate marker of bowel inflammation
Sammanfattning : The gas nitric oxide (NO) is a pluripotent biological messenger involved in numerous physiological and pathological processes in the gastrointestinal (GI) tract. In the intestinal mucosa NO is synthesized from the amino acid L-arginine via a reaction catalyzed by NO synthase (NOS). LÄS MER
19. Gastrointestinal Disorders in Women
Sammanfattning : Abstract: This doctoral thesis has sought to clarify the influence of gender in gastrointestinal (GI) disorders. Women with different hormone profiles were investigated, their colonic microbiota was characterized, and the impact of lifestyle and risk factors for GI disease were examined. LÄS MER
20. Genetic variation of tight junction structures in intestinal inflammation
Sammanfattning : The epithelial barrier facing the external environment in the gastrointestinal (GI) tract is comprised of several components, including the tight junction (TJ) structures observed for the first time in 1963. TJ structures, which are multiprotein complexes composed of transmembrane proteins and a diverse spectrum of intracellular components, create a primary barrier to diffusion of ions, solutes, and water and they concomitantly prevent permeation of pro-inflammatory factors, such as pathogens, toxins, and antigens.
