Abstract

fetched live from OpenAlex

; P = 0.005) in LAD + PAB vs LAD hearts. Mechanistically, we observed reduced LV fibrosis (9.8% [Q1-Q3: 7.7%-13.4%] vs 17.4% [Q1-Q3: 14.8%-20.2%]; P = 0.003) and fibroblast cellular senescence (5.7% [Q1-Q3: 4%-10.7%] vs 16.1% [7.6%-18.4%], P = 0.029), and preserved phospholamban (PLN) phosphorylation in the LV of LAD + PAB vs LAD rats (increased PLN/PLN: 0.6 ± 0.1 vs 1.0 ± 0.1; P = 0.008). In our model, PAB induced positive LV remodeling and improved LV systolic-diastolic function. PAB stimulated biventricular compensated hypertrophy that may constitute a potential adaptive mechanism which can rescue residual LV function and limit LV fibrosis/injury.

Teacher imitation

Not 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.
