Cyclic azapeptide cluster of differentiation-36 receptor modulator attenuates left ventricular injury and temporarily reduces long-chain fatty acid accumulation after myocardial ischemia-reperfusion in mice
Bibliographic record
Abstract
Abstract Ischemic heart disease remains a leading global cause of death. We investigated the cardio-protective effects of the selective cluster of differentiation-36 receptor (CD36) modulator azapeptide MPE-298 in a mouse model of myocardial ischemia-reperfusion. Before reperfusion, a single intravenous dose of azapeptide MPE-298 reduced infarct size by 37% and transiently decreased left ventricular (LV) long-chain fatty acid (LCFA) accumulation, independently of saturation status. Metabolomic profiling revealed shifts in amino acids involved in energy production and antioxidant defense. Gene expression analysis showed transient modulation of oxidative stress and inflammation in both heart and adipose tissue. Modulation of CD36 by azapeptide MPE-298 exhibited therapeutic potential for treating acute myocardial ischemia and reperfusion by supporting metabolic recovery and limiting excess LCFA uptake.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
