Effect of nanosilver particles on metabolism and cortisol release in rainbow trout (Oncorhynchus mykiss)
Bibliographic record
Abstract
Nanosilver (nAg) is a nanoparticle incorporated into products for its antimicrobial properties that causes diverse toxic effects. This study investigated the effects of nAg on metabolic rate and stress response in rainbow trout (Oncorhynchus mykiss Walbaum 1792). Fish were exposed to environmentally-relevant concentrations of nAg (average 0.28 μg l-1) and higher (average 47.60 μg l-1) for 28 days (d). Measurements of cortisol, growth, condition (K), and hepatosomatic index (HSI) were analyzed, as well as metabolic measurements. Cortisol concentrations were higher in all nAg exposures, and were significantly elevated in high exposures. No significant effects of nAg exposure were observed on metabolic variables, growth or condition. There was a significant effect of time and treatment on HSI, but no discernible trend. There was also a significant increase in cortisol in fish measured for metabolic variables. Overall nAg was seen to engage the stress response, but not affect metabolism or morphometric measures.

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.
