Abstract
Oxidative modification of low-density lipoprotein (LDL) is thought to play a key role in atherosclerotic plaque formation. Currently, there is a renewed interest in ginger because of its antioxidants and cardioprotective properties. The effects of ethanol, methanol, ethyl acetate, and hexane solvent extracts of ginger and pure major ginger constituents on Cu(2+)-induced oxidation of human LDL in vitro were examined. The LDL oxidation inhibition by ethanol, methanol, ethyl acetate, and hexane extracts of ginger was 71%, 76%, 67%, and 67%, respectively, at their optimum extraction conditions. Inhibition of LDL oxidation by water extracts of ginger, which was prepared by ultrasonic-assisted extraction conditions of 52°C for 15 min, was about 43%. Phenolic bioactives of ginger-6-gingerols, 8-gingerols, 10-gingerols, and 6-shogaol-seem to be strong inhibitors of Cu(+2)-induced LDL oxidation. Overall, ginger extracts, including the water extract possess the antioxidant activities to inhibit human LDL oxidation in vitro.

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
