Abstract
The effect of age on atrial natriuretic factor (ANF) metabolism in the rat was studied. Plasma ANF levels rose with age. A positive correlation was found between age and plasma ANF levels. Molecular forms of ANF were also examined. alpha-ANF and gamma-ANF were present in the circulation. The ratio of gamma-ANF/alpha-ANF increased with age. The atria were isolated and perfused to determine the ANF secretion rate. The spontaneous release of ANF decreased with age. The released ANF mainly consisted of alpha-ANF with a small amount of gamma-ANF. The ratio of gamma-ANF/alpha-ANF in the effluent increased with age. ANF concentrations in the atria varied with age, but the molecular forms did not. gamma-ANF was the main form found in the atria. These results suggest that ANF secretion as well as post-transcriptional processing is altered with age.

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
