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.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
