Abstract

fetched live from OpenAlex

The antioxidative effects of seven triterpenoids separated from labiatae Isodon were examined by testing their protection against DNA damage in human peripheral blood mononuclear cells induced by H2O2,inhibition of lipid peroxidation and DNA strand breakage.These triterpenoids exerted variably protective effects in these systems.Ursolic acid has the strongest protective effects in all three systems.2α,3β,dihydroxy-urs-12-en-28-oid acid are effective in inhibiting lipid peroxidatian but weak in protection DNA strand breakage.It's isomer 2α,3α,23-trihydroxy-urs-12-en-28-oic-acid showed opposite actions.Oleanolic acid is only effective in DNA damage induced by H2O2 in single cell.The relationship between antioxidations and structures are also discussed.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
