Promoting Peripheral Axon Regeneration across Nerve Gaps Post Trauma
Following peripheral nerve trauma, no technique induces axons to regenerate across a long nerve gaps and restore neurological function. The standard clinical “gold standard” technique for bridging nerve gaps is a graft of pure sensory nerve. However, sensory nerve grafts have many limitations because they only induce good axon regeneration across gaps <2 cm in length, for the nerves repaired <2...
متن کاملGiant Sequoia (Sequoiadendron giganteum) Regeneration in Experimental Canopy Gaps
Restoration of giant sequoia populations is a high priority for managers, but few experimental studies have examined the efficacy of restoration treatments. To inform giant sequoia restoration treatment options, we assessed the response of giant sequoia regeneration (germination, mortality, and growth) to experimental gaps within a native giant sequoia grove. We created experimental gaps, rangi...
متن کاملLianas suppress tree regeneration and diversity in treefall gaps.
Treefall gaps are hypothesized to maintain diversity by creating resource-rich, heterogeneous habitats necessary for species coexistence. This hypothesis, however, is not supported empirically for shade-tolerant trees, the dominant plant group in tropical forests. The failure of gaps to maintain shade-tolerant trees remains puzzling, and the hypothesis implicated to date is dispersal limitation...
متن کاملFerulic Acid Enhances Peripheral Nerve Regeneration across Long Gaps
This study investigated the effect of ferulic acid (FA) on peripheral nerve injury. In the in vitro test, the effect of FA on viability of Schwann cells was studied. In the in vivo test, right sciatic nerves of the rats were transected, and a 15 mm nerve defect was created. A nerve conduit made of silicone rubber tube filled with FA (5 and 25 μg/mL), or saline (control), was implanted into the ...
متن کاملrelationship between soil characteristics and beech regeneration density in canopy gaps with different sizes
in temperate forests canopy gaps play an important role in driving stand dynamics. the purpose of this research was to compare soil characteristics in forest gaps with several size and its relation to beech regeneration density in lalis forest, chalous. in order to investigate factors, three gap sizes as small gap (200 m2), medium gap (400 m2), and large gap (600 m2) with three replicate were s...
