Abstract
A plasma membrane-enriched fraction of vesicles from rat mesenteric artery possessed ATP-dependent calcium properties similar to those which have been reported previously. The catalytic subunit from a soluble, cyclic AMP-dependent protein kinase was prepared from the same tissue, in partially purified form. Calcium uptake by membrane vesicles increased 30% in the presence of this kinase. This effect was proportional to the kinase concentration, and was blocked by either catalytic subunit inhibitor or by prior boiling of the subunit preparation. Stimulation of calcium uptake by the kinase occurred maximally between 1 and 10 microM free calcium. These findings suggest that cyclic AMP and its dependent protein kinase may participate in the regulation of smooth muscle tension at high free myoplasmic calcium concentrations.

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
