Effect of<i>Lactobacillus plantarum</i>299v treatment in an animal model of irritable bowel syndrome
Bibliographic record
Abstract
Lactobacillus plantarum 299v is a probiotic bacterium effective in treating symptoms of irritable bowel syndrome. A mouse model of irritable bowel syndrome (IBS) can be produced by rectal administration of 1% allyl isothiocyanate (oil of mustard) in 30% ethanol. This study examined the effect of L. plantarum 299v on colonic inflammation and motility in the oil of mustard model. L. plantarum 299v (1×109 cfu) was gavaged for up to 28 days, beginning either 7 days before (pretreatment) or 8 days after oil of mustard administration (post-treatment). Colonic interferon gamma (IFNγ) release as an assessment of the inflammatory response was measured at day 4 and day 20 following oil of mustard administration. Small intestinal transit was assessed via the dye-transit score technique at day 20. L. plantarum 299v reduced inflammation at both day 4 and day 20 and normalized intestinal transit rates in the oil of mustard murine IBS model.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
