The Antigenicity of Rat Mammary Tumours, Induced by 7,12-Dimethylbenz(α)anthracene
Bibliographic record
Abstract
(1) Homogenates of rat mammarytumours induced by 7,12-Dimethylbenz(a)anthracene cause the formation of specific antisera in rabbits. (2) Absorption against relevant normal tissues and rat serum eliminates non-specific precipitations. (3) By the Ouchterlony double-diffusion method in agar, all the tumours tested formed well-defined precipitation lines against the antisera from immunized rabbits, within 24 h at room temperature. (4) Precipitation lines were observed regardless of the histological type of tumour from which the homogenate was obtained. The tumour histology ranged from examples of malignant adenocarcinomas to benign hyperplasia. (5) The process of growth, be it benign or malignant at the time when the tumour was removed seems to be closely associated with the presence of a specific protein, which by the method used could not be detected in simple mammary hyperplasia (due to pregnancy or lactation).

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.
