Abstract
Release of platelet antiheparin activity (platelet factor 4, PF4) induced by collagen and l-epinephrine, is normal in newborn infants without antenatal drug exposure. In contrast, PF4 release in platelets of infants of mothers with membrane-stabilizing drug ingestion is decreased to a greater extent than in their respective mothers. Platelet aggregation gives a qualitative indication of response. Platelets of mothers with antenatal drug exposure and those of their infants showed only a one-wave response to adenosine diphosphate, while platelets of these same mothers still showed a two-wave aggregation response to l-epinephrine. In contrast, platelets of all neonates lacked epinephrine-induced aggregation response, even when washed and resuspended in adult plasma. Our studies show that prenatal drugs have an effect on the platelet release mechanism in both mothers and their exposed infants; but the effect on the epinephrine-induced platelet response is less in mothers. Newborn infants have different aggregation and platelet release response to epinephrine which suggests that platelet aggregation and the release reaction can occur independently of each other.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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
