Abstract

fetched live from OpenAlex

Administration of selected concentrations of ebselen and N-acetyl cysteine have been proven to display an antioxidant potential based on their effect on markers of T cell integrity and function in human peripheral blood mononuclear cells and CD4(+) T cell clones. Here we assessed the impact of various antioxidant concentrations on replicative aging of primary human fibroblast strains derived from embryonic lung (MRC-5) and foreskin (HFF). None of the antioxidant concentrations affected the cumulative population doublings, levels of oxidative DNA damage, intracellular GSH:GSSG ratio, potency of heat shock responses and the induction of senescence in both fibroblast strains. Our results showed no effect of both antioxidants on primary fibroblast strains and reveal their cell type specific antioxidant potential.

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.
