Abstract

fetched live from OpenAlex

Beta-methyl-amino-L-alanine, (BMAA), is found in multiple components of the traditional Chamorro diet of Guam and this confounds epidemiological analysis based on a single dietary item. However, using hair as a non-invasive measure of BMAA exposure may help determine risks for developing motor neuron disease. BMAA found in brain tissues of patients with ALS/PDC and not generally in controls suggests that BMAA crosses the blood-brain barrier in patients with disease and is associated with neurodegenerative disease. An examination of frozen versus fixed autopsy tissue from ALS/PDC patients suggests that earlier studies of BMAA in ALS/PDC patients based on fixed tissues may have underestimated the concentration of BMAA in brain tissues. We suggest that the Chamorro people are exposed to chronically low levels of BMAA in the diet and that further research is needed to understand chronic BMAA toxicity.

Full frame distilled prediction

Teacher imitation

Not 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.
