Abstract

fetched live from OpenAlex

Growth hormone (GH) secretion is controlled by growth hormone releasing factor (GRF) but changes in the circulating level of this hormone are difficult to measure. Insulin-like growth factor (IGF-I) is a GH-dependent growth factor which significantly but slightly inhibits stimulated GH release in vitro. We have tested the effects of GRF and IGF-I on GH release in pregnancy, a state in which serum concentrations of GH are elevated and levels of IGF-I are lowered. We have found, in a system of acutely dispersed adenohypophysial cells prepared from pregnant (day 21-23) or control cycling female rats, that adenohypophysial cells from pregnant rats have an increased GH release with GRF. In contrast, IGF-I inhibition is similar but slightly smaller. These altered responses may result in elevated serum GH levels during pregnancy.

Full frame distilled prediction

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.
