Abstract

fetched live from OpenAlex

Rhamnogalacturonan (RGal) is a polysaccharide isolated from Acmella oleracea that ameliorates the intestinal barrier in an ulcerative colitis model induced by dextran sulfate sodium (DSS) and in Caco-2 cells. Here we investigate if RGal could reduce visceral pain, inflammation, oxidative stress and gastrointestinal dysmotility. Acetic acid, capsaicin or mustard oil were used to assess the visceral pain in normal mice. Ulcerative colitis was induced with DSS and RGal (10 mg/kg) was given orally for 7 days. RGal reduced abdominal contortions, cell migration, capsaicin, and mustard oil-induced visceral nociception. RGal reduced the visceral hypersensitivity, myeloperoxidase, lipid hydroperoxide and restored the glutathione, glutathione S-transferases, and superoxide dismutase levels and gastrointestinal motility, and protected the colonic epithelium and enteric neurons. RGal attenuates inflammation and consequently pain and intestinal motility; and could be a promising candidate for the treatment of ulcerative colitis. However, studies regarding the mechanism of action of RGal merited exploring further.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
