Development of γ-Glutamyltranspeptidase Activity in Mouse Small Intestine: Influence of Cortisone and Thyroxine
Bibliographic record
Abstract
The fetal and postnatal development of gamma-glutamyltranspeptidase (gamma-GT) activity has been examined in the different parts of the mouse small intestine. At 17 days of gestation, gamma-GT is present in all intestinal thirds and a decreasing gradient of activity from the proximal to the distal segments is already established. From 17 days of gestation up to 5 days after birth, a dramatic fall of activity is observed in all segments. gamma-GT activity reaches adult level before weaning in the proximal segment while it increases only during the 3rd postnatal week in the middle and distal intestinal segments. Daily administration of cortisone acetate (25 microgram/g b.w./day) for 3 days to 8-day-old mice elicits a premature increase of gamma-GT activity in all intestinal thirds, the maximal increase being observed in the proximal segment. On the other hand, thyroxine (1 microgram/g b.w./day) has no or little effect on the normal development of gamma-GT activity.

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.
