HIV infection is associated with a less aggressive phenotype of inflammatory bowel disease. A multicenter study of the ENEIDA registry.

Background: The coexistence of human immunodeficiency virus (HIV) infection and inflammatory bowel disease (IBD) is uncommon. Data on the impact of HIV on IBD course and its management is scarce.

Aim: To describe the IBD phenotype, therapeutic requirements and prevalence of opportunistic infections (OI) in IBD patients with a coexistent HIV infection.

Are the Main Methionine Sources Equivalent? A Focus on DL-Methionine and DL-Methionine Hydroxy Analog Reveals Differences on Rainbow Trout Hepatic Cell Lines Functions.

The replacement of fishmeal by plant proteins in aquafeeds imposes the use of synthetic methionine (MET) sources to balance the amino acid composition of alternative diets and so to meet the metabolic needs of fish of agronomic interest such as rainbow trout (RT-). Nonetheless, debates still exist to determine if one MET source is more efficiently used than another by fish. To address this question, the use of fish cell lines appeared a convenient strategy, since it allowed to perfectly control cell growing conditions notably by fully depleting MET from the media and studying which MET source is capable to restore cell growth/proliferation and metabolism when supplemented back.
