No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

Background: Phosphorylated alpha-synuclein (P-aSyn) is a biomarker for Parkinson's disease (PD), with potential relevance in intestinal inflammatory disorders. Objectives: This study examines the distribution of P-aSyn in colonic tissues of patients with diverticular disease (DD) compared to age-matched controls. Methods: P-aSyn distribution was analyzed in colon samples of 45 patients with diverticulitis (D-itis), 12 with diverticulosis (D-osis), and 30 controls via immunohistochemistry. Results: P-aSyn immunoreactivity was found along enteric neurons of the myenteric and submucosal plexus in 93.1 % of participants, with similar distribution across D-itis, D-osis, and controls. Elevated reactivity appeared in 16.7 % of D-osis, 19.6 % of D-itis, and 30.0 % of controls. Conclusion: P-aSyn presence in colonic tissue did not significantly differ between DD patients and controls, suggesting that DD-related inflammation does not notably affect P-aSyn expression. Further research is warranted to explore aSyn roles within the enteric nervous system in intestinal inflammatory disorders and their relation with neurodegenerative diseases.

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.
