SODIUM NITROPRUSSIDE TOXICITY IN<i><scp>D</scp></i><i>rosophila melanogaster</i>: DELAYED PUPATION, REDUCED ADULT EMERGENCE, AND INDUCED OXIDATIVE/NITROSATIVE STRESS IN ECLOSED FLIES
Bibliographic record
Abstract
The toxicity of sodium nitroprusside (SNP) was tested on the Drosophila melanogaster model system. Fly larvae were raised on food supplemented with SNP at concentrations of 0.01-1.5 mM. Food supplementation with SNP caused a developmental delay in flies and reduced adult eclosion. Biochemical analyses such as levels of oxidative stress markers and activities of antioxidant and associated enzymes were carried out on 2-day-old flies emerged from control and SNP-fed larvae. Larval exposure to SNP resulted in lower activities of aconitase and catalase in adult flies relative to the control cohort. However, larval treatment with SNP led to higher carbonyl protein content and higher activities of superoxide dismutase, glucose-6-phosphate dehydrogenase, thioredoxin reductase, and glutathione-S-transferase in flies. Among the parameters tested, aconitase activity and developmental end points may be useful early indicators of toxicity caused by SNP. The study also suggests that the toxicity of SNP may arise not just from its direct effects, but also from its decomposition products such as nitric oxide and iron ions.

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.
