Detection of Oxidative Damages on Viral Capsid Protein for Evaluating Structural Integrity and Infectivity of Human Norovirus
Bibliographic record
Abstract
The infectivity evaluation of noncultivatable viruses, such as human norovirus, is crucial to address needs for ensuring the safety in usage of water and marine products. In this work, we tested a new approach to evaluate viral particle integrity, in which oxidatively produced carbonyl groups on viral capsid protein were quantitatively detected. As a result, the decrease in the infectivity of human astrovirus, a representative enteric virus, positively correlated with the amount of oxidative damage on viral particles. Furthermore, when human norovirus was treated by 1 ppm free chlorine for 15 min, 49.93% of virions were recovered as oxidatively damaged particles, which represents a 5-fold increase over those treated by 0.5 ppm free chlorine for 15 min. The detection of the carbonylated viral particles could be a powerful tool for the evaluation of the decrease in the infectivity of noncultivatable viruses.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
