Abstract

fetched live from OpenAlex

The effect of oral administration of coumarin on the induction of breast tumors brought about by DMBA has been studied in female Wistar rats. Coumarin given before DMBA caused a significant dose-related suppression of the incidence of adenocarcinomas, although no histologic difference was found in the tumor between untreated and coumarin-treated rats. The growth rate, size and multiplicity were also reduced and tumor occurrence was delayed. Parallel with the suppression, hepatic drug metabolizing activity was decreased and serum prolactin level increased. Coumarin given after DMBA elicited no effect on the carcinogenic potency of DMBA. In contrast to the action on mammary tumorigenesis, coumarin provided no protection against hemopoietic and adrenocortical necrosis brought about by DMBA.

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.
