A unique distribution of laxative-induced spike potentials from the small intestine of the dog
The effects of castor oil and ricinoleic acid on small bowel electrical activity were studied in the fasted conscious dog and were compared to the effects elicited by two nonlaxative oils (triolein and oleic a...

Human surface electrogastrograms: AC and DC measurements
Both ac and dc abdominal electrical recordings were made on fasted and fed human subjects using a spatial array of 18 cutaneous, biopotential electrodes. Controlled skin puncture minimized cutaneous potentials...

Differences in the reducing power along the rat GI tract: Lower antioxidant capacity of the colon
The ability of the gastrointestinal (GI) tract, as well as other tissues, to cope with reactive oxygen species (ROS) efflux in pathological events is determined partly by epithelial antioxidant levels. These l...

Relation Between Colonic Inflammation Severity and Total Low-Molecular-Weight Antioxidant Profiles in Experimental Colitis
Tissue antioxidant status is altered as a response to oxidative stress. This oxidative stress, caused by reactive oxygen species, is associated with inflammatory bowel disease (IBD). Our aim was to examine the...

Intestinal Regrowth Is Amplified After Jejunal but Not Ileal Resection During Tapeworm Infection in the Rat
The ileum possesses functions required by a healthy individual that are not fully supplanted by the duodenum or jejunum. Evidence suggests that the ileum may also be necessary to maintain an enteric parasite–h...

Stem cell marker TRA-1-60 is expressed in foetal and adult kidney and upregulated in tubulo-interstitial disease
The kidney has an intrinsic ability to repair itself when injured. Epithelial cells of distal tubules may participate in regeneration. Stem cell marker, TRA-1-60 is linked to pluripotency in human embryonic st...
