The Effects of N-acetylcysteine on ifosfamide efficacy in a mouse xenograft model.
Bibliographic record
Abstract
BACKGROUND/AIM: Nephrotoxicity is observed in 30% of children treated with ifosfamide. We have shown that n-acetylcysteine (NAC) successfully mitigates nephrotoxicity of ifosfamide in cell and rodent models. However, before this treatment is evaluated clinically, it must be established that NAC does not interfere with the efficacy of ifosfamide. MATERIALS AND METHODS: Mice implanted with Ewing's sarcoma tumours received the following treatments: saline, ifosfamide, ifosfamide + NAC concurrently, pre-treatment with NAC + ifosfamide, or NAC alone. RESULTS: Median volumes of EW-7 tumour xenografts in mice treated with ifosfamide (n=8), ifosfamide with concurrent NAC therapy (n=7), and NAC pre-treatment (n=6) (p<0.05) were significantly reduced compared to median tumour volumes of control mice (n=6). None of the NAC treatments affected ifosfamide-mediated reduction in tumour volumes. CONCLUSION: NAC does not interfere with the efficacy of ifosfamide in a EW-7 xenograft model. These results support the clinical evaluation of NAC as a strategy against ifosfamide-induced nephrotoxicity in children.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
