Abstract

fetched live from OpenAlex

BACKGROUND: Vitamin D has antioxidant, anti-inflammatory, and neuroprotective properties, and may mitigate amyotrophic lateral sclerosis (ALS) pathology. AIMS: To determine the effects of dietary vitamin D(3) (D(3)) at 10-fold the adequate intake (AI) on functional and disease outcomes and lifespan in the transgenic G93A mouse model of ALS. METHODS: Starting at age 40 days, 32 G93A mice (21 M, 11 F) were provided ad libitum with either an adequate (AI; 1 IU/g feed) or high (HiD; 10 IU/g feed) D(3) diet. Differences were considered significant at P≤ 0.10, as this was a pilot study. RESULTS: For paw grip endurance, HiD mice had a 7% greater score between 60-133 d versus AI mice (P= 0.074). For motor performance, HiD mice had a 22% greater score between 60-133 days (P= 0.074) versus AI mice due to changes observed in male mice, where HiD males had a 33% greater score (P= 0.064) versus AI males. There were no significant diet differences in disease onset, disease progression, or lifespan. CONCLUSION: Although disease outcomes were not affected, D(3) supplementation at 10-fold the AI improved paw grip endurance and motor performance in the transgenic G93A mouse model of ALS, specifically in males.

Full frame distilled prediction

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.
