The Toxicity Assessment of ethyl p-hydroxybenzoate in Nematode C. elegans
Bibliographic record
Abstract
Ethyl paraben (EP) is an antiseptic commonly used in food, medicine, cosmetics, and children's products. Parabens are popular due to their broad antibacterial spectrum, low cost, and stable pH characteristics, and though once considered safe as well as effective, recent studies have shown that EP has considerable oestrogenic activity which has adverse effect on the human reproduction system. In our study, we used a Caenorhabditis elegans assay system to investigate EP toxicity and its underlying mechanism. We found that prolonged exposure to EP decreased body length and locomotion behavior in the nematodes. Furthermore, most of the toxicities were transferable. Locomotion behavior defects were only partially recovered in progeny, and higher concentrations caused more significant defects; locomotion behavior improved after subsequent exposure to mutants PMK-1 and PMK-3. Taken together, the results showed that EP exerts adverse effect on C. elegans and may induce toxicity through various underlying mechanisms.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
