Abstract

fetched live from OpenAlex

Objectives: Antenatal infection and anoxia are the main pathogenic processes triggering grey and white matter injuries in the brain of human neonates. We used our original rat model of neonatal brain lesions to study the role of pro-inflammatory cytokines in perinatal infectious and hypoxic-ischemic (H/I) aggressions of the brain. Methods: Infectious effect was produced by administrating lipopolysaccharide (LPS) intraperitoneally (ip) to pregnant rats from embryonic day 17 (E17) to E20. H/I was induced at postnatal day 1 (P1) by ligature of the right common carotid artery followed by exposure to hypoxia (7% O2) for 3.5 hours. IL-1, IL-2 and TNF mRNA and protein expressions were studied by RT-PCR and western blot. Brain injuries were examined at P3 and P8. Results: The extent of neuronal cell injury in the brain of rats exposed to postnatal H/I was significantly increased by antenatal exposure to LPS. Experimental aggressions resulted in IL-1beta, IL-2 and TNF-alpha mRNA and protein increases in the neonatal brain. Conclusion: Our animal model provides an experimental tool to study the role of pro-inflammatory cytokines in the pathophysiology of perinatal human brain lesions and subsequent cerebral palsy.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
