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

Objective To investigate the characteristics of hydrogen proton magnetic resonance spectroscopy (1H-MRS) in bilateral hippocampus in patients with general paresis of insane (GPI) and Alzheimer' s disease (AD). Methods The metabolic ratios of N-acetylaspartate/creatine (NAA/Cr), choline (Cho) /Cr, NAA/Cho, Cho/NAA and myo-inositol (mI) /Cr in bilateral hippocampus were determined by 1H-MRS in 35 patients with GPI, 27 patients with AD and 38 normal controls (NC), and the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment scale (MoCA) scores were evaluated on the same day. Results The NAA/Cr in bilateral hippocampus of patients with GPI and AD was significantly lower than that of the NC (left: 1.48±0.25, 1.52±0.28 and 1.71±0.36, F=5.928, P=0.004; right: 1.47±0.38, 1.62±0.36 and 1.82±0.42, F=7.309, P=0.001). The Cho/NAA in right hippocampus of patients with GPI (0.68±0.48) was significantly higher than that of the AD patients (0.49±0.15) and NC (0.53±0.14, P=0.024, P=0.045). There was no significant correlation between the metabolic ratios in bilateral hippocampus of patients with GPI and AD and the scores of MMSE and MoCA. Conclusion Patients with GPI and AD have neuronal dysfunction in bilateral hippocampus. Key words: Neurosyphilis; Alzheimer disease; Hippocampus; Magnetic resonance spectroscopy

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.
