Time-dependent effect of<i>in utero</i>inflammation: a longitudinal study in rats
Bibliographic record
Abstract
OBJECTIVE: To determine the impact of the duration of fetal exposure to inflammation on the neurological outcome of pups. METHOD: Time-pregnant Sprague-Dawley rats (n = 32) received intraperitoneal injection of lipopolysaccharides (LPS; 500 µg/kg), or an equivalent volume of vehicle 3, 6, 12 and 24 h before C-section. Maternal serum and amniotic fluid were tested for cytokines. Motor activity of resuscitated pups (n = 58) was analyzed using the open-field test (20 d). Brains were collected for histopathological examination. RESULTS: Perinatal mortality increased with the duration of fetal exposure to LPS. All parameters tested with the open-field test were lower in the LPS 12 h exposure group compared to the control group (p < 0.05). Tissue inhibitor of metalloproteinase 1 (TIMP-1) was statistically increased in maternal blood after 3, 6 and 12 h of LPS injection (p < 0.05 versus control). CONCLUSION: A threshold of duration of exposure to inflammation is demonstrated, before which delivery should be performed in order to prevent brain damage.

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.
