Abstract

fetched live from OpenAlex

Platelet-activating factor (PAF) has been shown to alter the trans-retinal potential recorded from light-stimulated isolated retina. In the present study, we investigated the effect of cholera and pertussis toxins on PAF-induced impairment of the electroretinogram (ERG). Administered alone, 2 x 10(-7) M PAF induced a very marked and rapid drop in the b-wave amplitude. When 75 micrograms/l of cholera toxin was coadministered with PAF in the perfusion solution, no b-wave drop was observed, suggesting that the effect of PAF on retinal function was mediated by GTP-binding protein (G protein). Similarly, a low dose of pertussis toxin (5 micrograms/l) was sufficient to antagonize the action of PAF on the ERG. Our results suggest that the irreversible and deleterious effect of PAF on ERG is mediated by a G protein mechanism, located in the neural retina.

Teacher imitation

Not 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.
