Abstract
Since no chelating agent has been clinically approved for the treatment of Cd(2+) intoxicated humans, we have previously investigated diethylenetriaminepentaacetic acid (Na5DTPA) to abstract this toxic metal from plasma proteins in vitro. In addition to the complete mobilization of Cd(2+), an inadvertent abstraction of Zn(2+) from metalloproteins was also observed. Therefore, we have evaluated the effect of ZnNa3DTPA on the plasma distribution of Ca, Cd, Cu, Fe and Zn after its addition to Cd(2+)-spiked rabbit plasma. ZnNa3DTPA was as efficient as Na5DTPA in abstracting Cd(2+) (100% removal), but it did not abstract Zn(2+). Thus, complexes between essential metals (e.g. Zn(2+)) and known chelating agents emerge as feasible candidates to decrease potential adverse side effects in patients.

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
