Abstract
The actions of efaroxan, a highly selective and potent alpha 2-adrenoceptor antagonist, on insulin secretion, cAMP levels, 86Rb+ efflux and ATP-regulated potassium (K+ATP) channels have been studied using isolated pancreatic islets of Langerhans and RINm5F cells. In the absence of an adrenoceptor agonist, efaroxan (1-100 microM) potentiated glucose-induced secretion over the range 4-10 mM glucose, but was without effect upon the maximal rate of secretion induced by 20 mM glucose. Efaroxan did not affect cAMP levels. Suppression of insulin release by the potassium channel opener diazoxide, was partially alleviated by efaroxan and was associated with an inhibition of the diazoxide-induced increase in the rate of 86Rb+ efflux. Using isolated patches of membrane we found efaroxan to be an effective blocker of K+ATP channels, with a KI value of 12 microM and a Hill coefficient of approximately 1. These data indicate that efaroxan promotes insulin secretion, in the absence of exogenous agonists, by a mechanism that involves inhibition of ATP-regulated K+ channels.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
