Abstract
Anesthesia and surgery have been reported to produce long-term cognitive problems, and to accelerate neurodegenerative disorders in the elderly. In previous work, we found that inhaled anesthetics enhance fibril formation and cytotoxicity of amyloid beta peptide. In this work we show that the inhaled anesthetics halothane (2-bromo-2-chloro-1,1,1-trifluoroethane) and isoflurane (1-chloro-2,2,2-trifluoroethyl difluoromethyl ether) also favor intermediate oligomers of amyloid beta(1-40), and reduce solubility of amyloid beta(1-40) monomer. Size-exclusion chromatography, analytical ultracentrifugation and photo-induced cross-linking experiments indicate halothane enhancement of oligomeric species having molecular weight approximately 44-100 kDa. Bis-ANS fluorescence experiments revealed that halothane stabilizes a population of diffusible oligomers relative to the monomer or the mature fibril. These data show that inhaled anesthetics lower the amyloid beta(1-40) concentration necessary to initiate oligomer formation, probably by preferential binding to intermediate oligomers en route to fibril formation.

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
