Deuterium‐reinforced polyunsaturated fatty acids improve cognition in a mouse model of sporadic Alzheimer's disease
Bibliographic record
Abstract
Oxidative damage resulting from increased lipid peroxidation ( LPO ) is considered an important factor in the development of late onset/age‐related Alzheimer's disease ( AD ). Deuterium‐reinforced polyunsaturated fatty acids (D‐ PUFA s) are more resistant to the reactive oxygen species‐initiated chain reaction of LPO than regular hydrogenated (H‐) PUFA s. We investigated the effect of D‐ PUFA treatment on LPO and cognitive performance in aldehyde dehydrogenase 2 ( Aldh2 ) null mice, an established model of oxidative stress‐related cognitive impairment that exhibits AD ‐like pathologies. Mice were fed a Western‐type diet containing either D‐ or H‐ PUFA s for 18 weeks. D‐ PUFA treatment markedly decreased cortex and hippocampus F 2 ‐isoprostanes by approximately 55% and prostaglandin F 2α by 20–25% as compared to H‐ PUFA treatment. D‐ PUFA s consistently improved performance in cognitive/memory tests, essentially resetting performance of the D‐ PUFA ‐fed Aldh2 − / − mice to that of wild‐type mice fed a typical laboratory diet. D‐ PUFA s therefore represent a promising new strategy to broadly reduce rates of LPO , and combat cognitive decline in AD .

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.
