Direct Detection of 8-Oxo-Deoxyguanosine Using UV Resonance Raman Spectroscopy
Bibliographic record
Abstract
8-oxo-deoxyguanosine (8-oxo-dG) is a major oxidative lesion in DNA and is responsible for mutation and cancer. Current techniques for detecting 8-oxo-dG are indirect methods. Thus, development of new methodologies is needed to directly detect such oxidative lesions. In this article, we have used ultraviolet resonance Raman (UVRR) spectroscopy as a novel analytical technique for the detection of 8-oxo-dG. Here, the UVRR spectrum of 8-oxo-dG was acquired and compared to that of deoxyguanosine (dG) and deoxyadenosine (dA). Data analysis shows a distinct UVRR spectrum of 8-oxo-dG with characteristic peaks. Detection of 8-oxo-dG was easily achieved from a mixture with dG. These results reveal that UVRR spectroscopy shows promise as a direct method for detecting 8-oxo-dG.

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.
