Oxydation radiolytique du tamoxifène par les radicaux libres <sup><b>·</b></sup>OH et (ou) HO<sup><b>·</b></sup><sub>2</sub>
Bibliographic record
Abstract
Tamoxifen is the most widely used antiestrogen in the treatment of breast cancer. In this work, we have studied its antioxidant properties. We have investigated the ability of tamoxifen to scavenge, in vitro, *OH and (or) HO2* free radicals that are produced by water radiolysis. Aqueous solutions of tamoxifen of concentrations ranging between 10(-5) and 2.5 x 10(-5) M have been irradiated (gamma 137Cs) in aerated acidic medium (H3PO4 10(-3) M or HCOOH 10(-1) M). The results show that tamoxifen reacts quantitatively with *OH free radicals but does not react with HO2* free radicals under our experimental conditions.

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.
