No Effect of Cyclooxygenase Inhibition on Plaque Size in Atherosclerosis-prone Mice
Bibliographic record
Abstract
OBJECTIVE: To study the role of cyclooxygenase (COX) inhibition on the development of advanced atherosclerosis in apolipoprotein E-deficient (apoE(-/-)) mice. DESIGN: Sixty apoE(-/-) mice were divided into three groups: a control group, a group fed standard mouse chow supplemented with 0.0067% (wt/wt) MF Tricyclic (selective COX-2 inhibitor), and a group fed the diet supplemented with 0.0134% (wt/wt) sulindac (non-selective COX inhibitor). Four months later, the mice were killed and the atherosclerotic plaque area in the aortic root was measured. RESULTS: Mean body weights did not differ at any time. The MF Tricyclic and sulindac groups had drug plasma levels of 1.31 +/- 0.11 and 0.84 +/- 0.23 micro g/ml, respectively. Plasma total cholesterol and triglyceride values were similar in all three groups. A small difference in plasma levels of high-density lipoprotein cholesterol was found between the groups (p = 0.03). Advanced atherosclerotic plaques were present in mice from all three groups, but there was no difference in mean plaque size between the groups (p = 0.9). CONCLUSION: Neither selective COX-2 nor non-selective COX inhibition influenced the development of advanced atherosclerosis in apoE(-/-) mice.

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.
