Abstract

fetched live from OpenAlex

Background/Objectives NX210c is a 12-amino acid peptide derived from conserved thrombospondin type 1 repeat sequences in the subcommissural organ-spondin, which has a unique multifunctional mechanism of action to ameliorate outcomes following neurological injuries. The aim of this study was to evaluate the efficacy of NX210c to promote functional recovery and tissue repair in a cervical traumatic spinal cord injury (SCI) model. Methods/Overview Adult female Wistar rats were subjected to a C6/C7 clip compression-contusion injury and treated once daily with intraperitoneal injections of NX210c (8 mg/kg) or its vehicle for 8 weeks, beginning 4 hours (h) or 8h post-injury (n=16-17/group), with concurrent neurobehavioural tests. Results Earlier NX210c administration at 4h increased forelimb grip strength (p<0.05) and improved several static and dynamic aspects of locomotion including regularity index and base of support of the forelimbs (CatWalk) (p<0.05). Delaying initial administration of NX210c to 8h, promoted weight gain, accelerated bladder control recovery from 14 to 9 days post-injury, and improved trunk balance (inclined plane) as early as one-week post-injury (p<0.05). 94% of NX210c-treated rats compared to 75% of vehicle controls observed weight support at the delayed initial injection timepoint. Histology (n=6/group) demonstrated greater white matter preservation and reduced cavity size at the injury epicenter, and higher neuronal soma counts caudally, with NX210c starting 8h post-injury compared to the vehicle (p<0.05). Conclusions NX210c targets various aspects of SCI, improving motor function, bladder control, white matter preservation, and neuronal counts, with more benefits observed at the later initial injection timepoint.

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.
