Abstract

fetched live from OpenAlex

OBJECTIVE: To investigate the combination therapy, consisting of hyperimmune bovine colostrum, N-acetyl cysteine, zinc and amoxicillin on the eradication of Helicobacter pylori in a mouse model. MATERIAL AND METHODS: C57BL/6 female mice (6 weeks of age) were inoculated with 0.1 ml of 1×10(9) H. pylori via a single oro-gastric gavage and were left infected for 4 weeks. Mice (n=9/group) were randomly allocated to receive by oral gavage (0.1 ml) HNZ (hyperimmune bovine colostrum+N-acetyl cysteine+zinc), HNZA (HNZ+amoxicillin; A), HNZA2 (2× amoxicillin; A2), HNZA5 (5× amoxicillin; A5), triple therapy (TT) or saline twice daily for 10 days. Bacterial load was assessed by culture. Gastric emptying was assessed by 13C-octanoic acid breath test. RESULTS: Mice receiving HNZ, HNZA, and HNZA2 have a 22%, 44% and 67% eradication rate, respectively. Eradication rate was 100% with HNZA5, TT and those animals receiving A5 alone. In H. pylori infected mice there was an increased gastric emptying time by 7.9, 3.7, 10.1 and 7.7 min for the TT, HNZ, HNZA2, and HNZA5, respectively, compared to saline. CONCLUSIONS: HNZ with the addition of a high dose of amoxicillin is effective at eradicating H. pylori in vivo as HNZA1 and HNZA2 did not give raise to eradication. The potency of the novel anti-H. pylori combination therapy may be due to the delayed gastric emptying.

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.
