Abstract

fetched live from OpenAlex

Compelling evidence points to oxidative stress as an important trigger in the complex chain of events leading to atherosclerosis. Randomized clinical trials have not provided definitive evidence of the beneficial effect of antioxidant vitamins. Problems associated with the use of vitamins include their potential pro-oxidant effects and the decreased absorption of natural gamma-tocopherol caused by alpha-tocopherol supplements. Probucol and amlodipine are more powerful lipophilic antioxidants than vitamin E. They also do not appear to have significant pro-oxidant properties. Probucol has been shown to prevent coronary restenosis after balloon angioplasty in clinical trials. Its high density lipoprotein-lowering effect, however, prevents it from being protective against progression of coronary atherosclerosis. Slowing or reversing the atherosclerotic process with an antioxidant likely requires the use of a powerful lipophilic antioxidant that has neutral or positive effects on serum lipids when given alone or in combination with a lipid-lowering agent.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
