Abstract

fetched live from OpenAlex

We examined two commercially available St. John's wort extracts and some of their constituents for their potential in inducing rat cytochrome P450 (CYP450) enzyme activities after oral administration. None of the extracts or pure constituents tested enhanced the hepatic cytochrome content or the activity of cytochrome P450 isozymes in rat liver microsomes. Our results demonstrated that the reported interactions between St. John's Wort and various other drugs are not mediated by CYP 450 isoforms present in rat liver.

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.
