Bovine ′Neurophysin II’ Stimulates Growth Hormone Release in the Estradiol-Primed Male Rat
Bibliographic record
Abstract
Basal plasma concentrations of growth hormone (GH) were monitored in both normal and estradiol-primed male rats by the collection of sequential blood samples from freely moving rats, via chronic intraatrial cannulae. Blood was sampled every 2 min for a period of 80 min and plasma GH levels determined by radioimmunoassay. The normal male rats displayed a pulsatile release of GH, while the estradiol-primed male rats exhibited a relatively steady level of plasma GH concentration. The rats exposed to high levels of estradiol (1.59 +/- 0.42 nmol/l plasma) also had a higher mean value of basal GH concentration. An injection of 100 micrograms/kg of bovine neurophysin II did not alter GH release in the normal male rats. However, it did significantly elevate GH levels in the estradiol-primed animals to a mean peak level approximately six times the mean basal level. The administration of 100 micrograms/kg of bovine neurophysin I to estradiol-primed male rats did not produce any change in plasma GH levels and thus eliminates the possibility of the nonspecific stimulation of neurophysin II on GH release.

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.
