Fruits and leaves from wild blueberry plants contain diverse polyphenols and decrease neuroinflammatory responses in microglia
Bibliographic record
Abstract
For the treatment of neurological disorders, polyphenols in Vaccinium berry species may be an effective addition to standard medicinal products. Polyphenols may reduce oxidative stress and inflammation, processes believed to contribute to disorders such as Parkinson’s disease. We performed an analysis of polyphenol content, biochemical attributes and neurobiological activity of extracts from wild blueberries native to Newfoundland and Labrador. Fruits and leaves of samples contained several polyphenolic compounds, such as anthocyanins, and demonstrated high antioxidant capacity. Cell cultures of microglia, the innate immune cells of the brain, were exposed to glutamate or α-synuclein in order to induce inflammatory responses, which decreased the amount of cells after 24 h. Overall, treatment of cells with fruit or leaf extracts inhibited cell death and decreased morphological criteria associated with inflammation. These results suggest that dietary intake of blueberry fruits and leaves or supplements may be protective against neurodegenerative disorders that include a neuroinflammatory component.

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.
