Effects of Corticotropin-Releasing Hormone and Adrenocorticotropin on Prostaglandin Output by Human Placenta and Fetal Membranes
Bibliographic record
Abstract
We have examined the possibility that corticotropin-releasing hormone (CRH) and adrenocorticotropin (ACTH) might affect prostaglandin (PG) E2 and PGF2 alpha output by term placenta, amnion and decidua during short-term (48-hour) culture, and that effects of CRH might be mediated by ACTH. In all three tissues PG output was stimulated by both CRH and ACTH. These effects were inhibited in the presence of antisera to CRH and to ACTH. Moreover, in placenta, but not in amnion or decidua, the stimulatory effects of CRH on PGE2 and PGF2 alpha output were attenuated in the presence of an antibody to ACTH. Our results support the possibility of paracrine stimulation by CRH and ACTH of PG production in intrauterine tissues, and suggest that in part the effects of CRH on placental PG output might be mediated through ACTH.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
