Targeting Nerve Fiber Outgrowth Inhibition After Experimental Spinal Cord Injury: A Systematic Review and Meta-analysis of Chondroitinase ABC.

Background: Spinal cord injury (SCI) can impair motor, sensory, and autonomic function. The formation of the glial scar comprises protective as well as inhibitory neurite outgrowth properties operated by the deposition of chondroitin sulfate proteoglycans (CSPG). Chondroitinase ABC (ChABC) can degrade CSPG and foster neuroaxonal plasticity as a therapeutic approach to restore locomotor function after SCI.

Assessing the locomotor demands of international men's and women's rugby sevens match-play according to passage of play.

This study aimed to evaluate the effect of discrete passages of play on locomotor demands of international men's and women's rugby sevens matches and their relationship with winning or losing. Thirteen men's and thirteen women's international rugby sevens players wore 10 Hz Global Positioning Systems during twelve Tokyo Olympic games matches (966 observations; 507 for men, 459 for women). Discrete ball-in-play periods were categorised as: 'Single-phase defence', 'single-phase attack', 'multi-phase defence', 'multi-phase attack', 'multi-phase defence to attack', or 'multi-phase attack to defence'.

Inhibition of the Nogo-pathway in experimental spinal cord injury: a meta-analysis of 76 experimental treatments.

Recovery after spinal cord injury (SCI) may be propagated by plasticity-enhancing treatments. The myelin-associated nerve outgrowth inhibitor Nogo-A (Reticulon 4, RTN4) pathway has been shown to restrict neuroaxonal plasticity in experimental SCI models. Early randomized controlled trials are underway to investigate the effect of Nogo-A/Nogo-Receptor (NgR1) pathway blockers.
