Abstract
Cell biology, as monitored with the fluorescent indicator dyes Alamar Blue and 5-carboxyfluorescein diacetate acetoxymethyl ester (CFDA-AM), and lens optical quality, as measured with an in vitro scanning laser system, have been used to evaluate in vitro the condition of porcine lenses after being placed in a culture medium. The measurements, beginning from week one of culture, were compared statistically. Optical quality and cellular viability, as measured with either dye, were unchanged in lenses that had been maintained for 6 weeks in modified M199 medium. Some lenses were treated with 0.152J/cm(2) UVB radiation, and a decline was observed after 48 hours in both optical and metabolic capabilities, as indicated by a decreased capacity of the lenses to reduce Alamar Blue. The measurements with CFDA-AM did not show complete concordance with the other indicators of lens health after UV treatment, making this dye less reliable as applied currently to lens cultures. Overall, the findings suggest that porcine lenses can be maintained for weeks in culture, and that their condition can be evaluated quantitatively by assays that probe cellular functions and optical properties. Such a system should prove valuable for in vitro ocular pharmacotoxicological research.

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 it
