Abstract
BACKGROUND: Pre-eclampsia, a hypertensive disorder of pregnancy is the main cause of fetal and maternal morbidity and mortality. Growing evidences suggest that placental oxidative stress involves in the pathogenesis of pre-eclampsia. The HSP70 is a novel marker of oxidative stress which binds with high avidity to LOX-1. The aim of this study was to evaluate the co-expression of HSP70 and LOX-1 in the placental tissues of normotensive and pre-eclamptic pregnancies. MATERIALS AND METHODS: The placental tissues were collected from 35 healthy women with normal pregnancies and 33 women with pre-eclampsia disorder. Expression of HSP70 and LOX-1 on the placental tissues was examined by using immunohistochemistry technique. The intensity of the molecules' expression was determined by semi-quantitative scoring. RESULTS: The 34.3% and 37.1% of the healthy women did not express the HSP70 and LOX-1 on their placenta, respectively. All pre-eclamptic patients expressed HSP70 and LOX-1 with various scores. Indeed, the majority of the pre-eclamptic subjects had ≥3+ scores of the expression of HSP70 and LOX-1 on their placenta (60.6% and 66.7%, respectively). The percentage of the ≥3+ scores of the expression of HSP70 and LOX-1 was significantly higher in patients than those in healthy women (p<0.0001 for both). Similarly, the majority of the pre-eclamptic subjects had ≥3+ scores of the co-expression of HSP70 and LOX-1 molecules (57.6%) which was significantly higher in patients than those in control group (p=0.0001). CONCLUSIONS: These results showed higher expression of HSP70 and LOX-1 in the placental tissues of pre-eclampsia patients which represent the possible contribution of these molecules in the disease pathogenesis. Further studies need to clarify their role in the pathogenesis of preeclampsia disorder.

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
