Abstract
Prostaglandins produced by the intrauterine tissues of both mother and fetus (myometrium, decidua, placenta, chorion, and amnion) are involved with all of the physiologies of parturition (membrane rupture, cervical dilatation, myometrial contractility, placental separation, and uterine involution). For parturition to occur, however, the intrauterine tissues need to first be activated to prepare for the work of labor, then stimulated to initiate labor. Prostaglandins normally are considered to be stimulators of the physiologies of labor. This review presents evidence that one prostaglandin, PGF2alpha, and its receptor, FP, are also activators, especially of the decidua. Stimulated by cytokines, the decidual synthesis of PGF2alpha and the expression of FP lead to increased matrix metalloproteinase activity, further enhancement of cytokine activity, increased decidual oxytocin and oxytocin receptor expression, decreased progesterone responsiveness, and possibly, enhanced expression of vascular endothelial growth factor. These collective actions prepare the decidua for its role in parturition.

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 it
