Protease activation during surgical stress in the rat small intestine.
BACKGROUND Surgical stress affects intestinal permeability and our earlier study using a rat model indicated that oxidative stress plays an important role in this process. Proteases are important mediators of cellular damage and are known to be activated in oxidative stress. This study looked at protease activity in enterocytes after surgical stress. METHODS Surgical stress was induced by ope...
متن کاملSurgical stress and the small intestine: role of oxygen free radicals.
BACKGROUND Any surgical procedure can be associated with altered intestinal function. The mechanism involved in these changes at the cellular level during surgical stress has not been worked out. This study looked at the biochemical and functional alterations, along with ultrastructural changes, in the intestine during surgical stress in a simple rat model. METHODS Surgical stress was induced...
متن کاملSurgical stress-induced alterations in retinoid metabolism in the small intestine: role of oxygen free radicals.
Oxidative stress in the small intestine can result in altered cell proliferation, migration, and differentiation of villus-crypt cells. Retinoid metabolism is recognized as an important mediator of cellular differentiation in the intestine. This study examined the effect of oxidative stress in retinoid metabolism in a surgical stress model. Surgical stress was performed by handling the intestin...

متن کاملMicroRNA Transcriptome in Swine Small Intestine during Weaning Stress
MicroRNAs (miRNAs) play important roles in intestinal diseases; however, the role of miRNAs during weaning stress is unknown. In our study, six jejunal small RNA libraries constructed from weaning piglets at 1, 4 and 7 d after weaning (libraries W1, W4 and W7, respectively) and from suckling piglets on the same days as the weaning piglets (libraries S1, S4 and S7, respectively) were sequenced u...
