Cyclic 3’5’-Adenosine Monophosphate in the Hypothalamo-Neurohypophysial System of Normal, NaCl-Treated and Lactating Rats
Bibliographic record
Abstract
The presence and production of cyclic 3', 5'-adenosine monophosphate (cAMP) were investigated in the hypothalamus and neural lobe of the rat. Theophylline (concentrations from 10(-3) to 8 X 10(-3) M) increased the in vitro content of cAMP in the isolated neural lobe and in hypothalamic tissue samples containing supraoptic (SO) or paraventricular (PV) nuclei. Acetylcholine (ACH; 10(-2) and 10(-4) M) or carbachol (10(-4) M) did not increase cAMP content in the isolated neural lobe. Small increases were apparent (p less than 0.05, t-test for paired samples) in the hypothalamus. The amounts of cAMP were significantly higher in isolated neural lobes but not in hypothalami of NaCl-treated or lactating as compared to control rats. Presence of cAMP in the neural lobe and activation of adenylate cyclase under stimulated hormone release conditions indicate a possible involvement of cAMP in the process of neurohypophysial hormone secretion.

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.
