11.   The duodenal mucosa is normally challenged by intermittent exposure to acid, because of the periodic emptying of the gastric content into the duodenal lumen.

12.   This study aimed to investigate whether the resistance to acid of the duodenal mucosa can be modulated by the dietary content of fatty acids.

13.   Exposure of the duodenal mucosa to a mild dose of acid significantly enhanced mucosal resistance to a subsequent acid challenge.

14.   This study aimed to investigate whether changes in the type ofdietary fat would influence the susceptibility of the duodenal mucosa to acid induced lesions.

15.   Diet supplementation with fatty acid precursors of eicosanoid synthesis may influence the adaptive response of the duodenal mucosa to acid.

16.   Diets rich in polyunsaturated fatty acids enhance the phenomenon of adaptive cytoprotection and render the duodenal mucosa more resistant to acid.

17.   We aimed at studying the histology of the duodenal mucosa in the presence or absence of chronic NSAID intake, H pylori, and duodenal ulcers.
