Abstract
Many different types of tumour have previously been shown to over-express cell-surface receptors involved in the uptake of Vitamin B12 (VB12). We have examined the potential of using VB12 as a targeting agent for the delivery of pHPMA-conjugated daunomycin in four murine tumour models. VB12-targeted-duanomycin-HPMA conjugates were found to increase both the number of survivors and the survival time of tumour-bearing mice. The data indicate that VB12 may be highly effective in enhancing the efficacy of polymer-bound cytotoxins, particularly in those tumours that over-express receptors involved in vitamin B12 uptake.

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 it
