UNLABELLED Hepatic encephalopathy (HE) represents a dysfunctional gut-liver-brain axis in cirrhosis which can negatively impact outcomes. This altered gut-brain relationship has been treated using gut-selective antibiotics such as rifaximin, that improve cognitive function in HE, especially its subclinical form, minimal HE (MHE). However, the precise(More)
Minimal hepatic encephalopathy (MHE) impairs daily functioning in cirrhosis, but its functional brain impact is not completely understood. To evaluate the effect of rifaximin, a gut-specific antibiotic, on the gut-liver-brain axis in MHE. Hypothesis: Rifaximin will reduce endotoxemia, enhance cognition, increase activation during working memory(N-back) and(More)
Learning to lever-press for food in rats may be experimentally analyzed according to (a) association of lever-pressing with food reinforcement; (b) development of the behavior of lever-pressing. The latter was studied in two strains of rats with a high or low level of 2,3-diphosphoglycerate (DPG) in erythrocytes. Twelve males from each strain, previously(More)
