Abstract
BACKGROUND: Microdose lithium is protective against Alzheimer's disease (AD), although the precise mechanisms through which its protective effects are conferred remain unclear. OBJECTIVE: To further examine the effects during the earliest stages of Aβ pathology, we evaluated whether NP03, a microdose lithium formulation, modulates Aβ-mediated oxidative damage and neuroinflammation when applied to a rat transgenic model of AD-like amyloidosis overexpressing amyloid precursor protein (APP). METHOD: McGill-R-Thy1-APP transgenic rats and wild-type littermates were treated with NP03 or vehicle formulation for 8 weeks beginning at 3 months of age - a phase preceding Aβ plaque deposition in the transgenic rats. RESULTS: Oxidative and nitrosative stress markers, protein-bound 4-hydroxynonenal (HNE) and proteinresident 3-nitrotyrosine (3-NT), inflammatory cytokines production, as well as microglial recruitment towards Aβ-burdened neurons were assayed. NP03 significantly decreased cerebral HNE and 3-NT, and reduced production of pro-inflammatory cytokines in McGill-R-Thy1-APP transgenic rats. NP03 further reduced expression of microglia surface receptor Trem2 and led to a corresponding reduction in microglia recruitment towards Aβ-burdened neurons in the CA1 region of the hippocampus. CONCLUSION: These results suggest that NP03 may function to slow the AD-like pathology in part by modifying oxidative/nitrosative damage and neuroinflammation, raising the possibility that low doses of microencapsulated lithium might be of therapeutic-preventive value during very early or preclinical AD.

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
