Abstract
A number of Na+ and K+ transport pathways have been identified in the alveolar epithelium and multiple inhibitors have been used to uncover these mechanisms. However, the effect of phloretin, a small dipolar nonelectrolyte compound which exerts many effects on membrane transport on Na+ and K+ uptake in alveolar epithelial cells, is not known. The purpose of this study was then to determine the impact of phloretin in Na+ and K+ uptake in cultured rat alveolar type II cells. Phloretin at a dose of 250 microM decreased Na+ uptake by 80% and K+ uptake by 90%. This decrease in Na+ and K+ uptake was not associated with a cytotoxic effect of phloretin, but this treatment did decrease ATP levels in the cells to 80% of the control cells value by 5 minutes and to 95% by 10 minutes. Our study demonstrates that phloretin is a nonspecific inhibitor of ions transport in alveolar type II cells. This inhibition is probably mediated by a reduction of intracellular ATP content.

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 it
