TL;DR: It is concluded that, early in rotavirus enteritis, Arg has no impact on diarrhea but augments intestinal protein synthesis in part by p70(S6k) stimulation, while improving intestinal permeability via a mammalian target of rapamycin/p70( S6k)-independent mechanism. (via Semantic Scholar)

TL;DR: It is shown that intestinal MGAT and DGAT activities decrease after ischemic damage, yet recover rapidly in bowel exposed to Gln and/or TGF-α, which could improve the efficacy of enteral feeding in infants recovering from bowel damage. (via Semantic Scholar)

1997 journal article

Is reperfusion injury an important cause of mucosal damage after porcine intestinal ischemia?

SURGERY, 121(5), 526–534.

By: A. Blikslager n , M. Roberts n, J. Rhoads n & R. Argenzio n

MeSH headings : Animals; Female; Intestinal Mucosa / enzymology; Intestinal Mucosa / pathology; Intestines / blood supply; Intestines / enzymology; Ischemia / complications; Ischemia / metabolism; Male; Peroxidases / metabolism; Reperfusion Injury / complications; Reperfusion Injury / metabolism; Swine; Xanthine Dehydrogenase / metabolism; Xanthine Oxidase / metabolism
TL;DR: Reperfusion injury may not play an important role in intestinal injury under conditions of complete mesenteric ischemia and low-flow states in the pig, which may result from low xanthine oxidase-xanthine dehydrogenase levels, which are similar to those found in the human being.
