Abstract
In this study, we demonstrate the use of proteomics to detect regional differences in protein levels between the reperfused ischemic zone (IZ) and the nonischemic zone (NIZ) of dog hearts which were subjected to in vivo ischemia-reperfusion injury. Using the two-dimensional gel electrophoresis (2-DE) technique, we identified five proteins that were differentially expressed in the IZ versus NIZ: (1) the alpha subunit of ATP synthase isoform precursor was decreased 1.71-fold; (2) creatine kinase M chain was decreased 1.72-fold; (3) NAD+-isocitrate dehydrogenase, alpha subunit was increased 8.34-fold; (4) ATP synthase D chain, mitochondrial was increased 3.02-fold; (5) ventricular myosin light chain-1 was decreased 2.02-fold. Additionally, we found that the level of actin was decreased 2.6-times in the IZ compared to the NIZ on Western blot analysis but was unchanged on 2-DE.

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
