Effect of Secretin on Myoelectrical and Mechanical Activity of the Isolated Canine Stomach Perfused ex vivo
Bibliographic record
Abstract
Totally isolated whole canine stomachs, perfused ex vivo with homologous blood, were used for recording of myoelectrical and mechanical activity prior to and following the injection of secretin. Secretin was given as flash injections (0.5 - 32 U) or constant infusions (60 U/h). Background stimulation of stomachs was obtained by intragastric instillation of fluid, by the infusion of pentagastrin or bethanechol chloride, and by electrical stimulation of the Latarjet branch of the vagus nerve. Hormones were injected into the gastric arterial circulation. Secretin had no effect on the frequency of electrical control activity. Secretin inhibited electrical response activity when injected against the background of electrical vagus stimulation. Secretin also inhibited or decreased mechanical activity of the gastric antrum, recorded at the site of the antral strain gauge.

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.
