Regenerative arrest of inflamed peripheral nerves: role of nitric oxide
Bibliographic record
Abstract
Inflammation can both support and hinder regeneration. In this work, we asked whether regeneration of peripheral nerve axons is facilitated or interrupted when it proceeds through a zone of local but nondirected inflammation. Regeneration was examined in new nerve bridges forming through conduits connecting transected rat sciatic nerves. The conduits, infused with lipopolysaccharide to generate a sterile and nondirected inflammatory response, had substantial rises in inducible nitric oxide (iNOS) mRNA synthesis. iNOS was expressed within macrophages just beyond the zone of axon regrowth. Under these conditions, there was complete interruption of regenerative bridge formation in all instances without axon regrowth across the transection. In a separate cohort, infusion of a broad-spectrum NOS inhibitor (Nomega-nitro-L-arginine-methyl ester) into the conduit salvaged bridge formation in a proportion (3/8) of rats. Our findings indicate that local inflammatory conditions inhibit regenerative events and that nitric oxide may contribute to these events.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
