Abstract
Although the structures of Thioflavin T and another benzothiazole, BTA-1, are similar, they bind to A beta non-competitively, probably to different sites on the A beta(1-40) fibrils. The amyloid fibril-induced fluorescence of ThT that corresponds to a fraction of total ThT binding is not displaced by high concentrations of (S)-naproxen or (R)-ibuprofen, which are reported to potently block high affinity binding of the radiolabeled malononitrile FDDNP and derivatives. The binding of the benzothiazole ligands is significantly substoichiometric with respect to A beta(1-40) monomer peptide, unlike Congo Red, which binds to A beta(1-40) fibrils on a 1:1 basis with monomer peptide. These results indicate that there are multiple domains for ligand binding to amyloid fibrils and suggest that it may be possible to design ligands that bind selectively to particular forms of fibrils that are connected with the pathogenesis of Alzheimer's disease and potentially other protein misfolding diseases.

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.
