Abstract
PROBLEM: L-selectin ligand has displayed mediating adhesion at the maternal-fetal interface. Therefore, we investigated the impact of L-selectin ligand on establishing pregnancy in women undergoing in vitro fertilization and embryo transfer (IVF-ET). METHOD OF STUDY: Endometrium between cycle days LH +6 to +9 was obtained from 56 Chinese women referred for IVF and tested for L-selectin ligand by immunohistochemistry and Western blot. The standard gonadotropin-releasing hormone agonist long protocol was used for ovarian stimulation. RESULTS: L-selectin ligand was localized in the endometrial gland and luminal epithelial cells. Western blot analysis of endometrium identified four bands and levels of component 1, 2 and 4 were significantly higher in the pregnancy group than in the non-pregnancy group (P < 0.05). Clinical pregnancy and implantation rates were higher in patients with high level L-selectin ligand compared with those with low level (53.6%versus 25.0%, and 27.1%versus 12.1%, respectively, P < 0.05). CONCLUSION: The presence of higher level L-selectin ligand was associated with a better pregnancy outcome.

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
