A missense mutation in human INSC causes peripheral neuropathy.

PAR3/INSC/LGN form an evolutionarily conserved complex required for asymmetric cell division in the developing brain, but its post-developmental function and disease relevance in the peripheral nervous system (PNS) remains unknown. We mapped a new locus for axonal Charcot-Marie-Tooth disease (CMT2) and identified a missense mutation c.209 T > G (p.

Warm acupuncture therapy alleviates neuronal apoptosis after spinal cord injury via inhibition of the ERK signaling pathway.

Purpose: Warm acupuncture (WA) therapy has been applied to treat spinal cord injury (SCI), but the underlying mechanism is unclear. The current study attempted to explore the WA therapy on neuronal apoptosis of SCI and the relationship with the extracellular signal-regulated kinase (ERK) signaling pathway.

Methods: The rat SCI models were established by the impact method.

[Effect of moxibustion on Nogo/neurotrophin receptor signaling pathway in rats with cerebral ischemia/reperfusion injury].

Objective: To observe the effect of moxibustion treatment on the expression of Nogo-A, Nogo receptor (NgR), neurotrophin receptor p75 (p75NTR) and leucine rich repeat and Ig domain containing 1 (Lingo-1) in brain tissue of rats with cerebral ischemia/reperfusion injury (CI/RI), so as to analyze its mechanism underlying improvement of CI/RI.

Methods: Male SD rats were randomly divided into sham operation group (16 rats), model group (17 rats), NEP1-40 (extracellular peptide residues 1-40, a blocker targeting NgR) group (model+blocker, 17 rats) and moxibustion group (model+moxibustion, 17 rats). The CI/RI model was established by occlusion of the left middle cerebral artery (MCAO).

Effect of electroacupuncture on the mRNA and protein expression of Rho-A and Rho-associated kinase II in spinal cord injury rats.

Electroacupuncture is beneficial for the recovery of spinal cord injury, but the underlying mechanism is unclear. The Rho/Rho-associated kinase (ROCK) signaling pathway regulates the actin cytoskeleton by controlling the adhesive and migratory behaviors of cells that could inhibit neurite regrowth after neural injury and consequently hinder the recovery from spinal cord injury. Therefore, we hypothesized electroacupuncture could affect the Rho/ROCK signaling pathway to promote the recovery of spinal cord injury.

Nonlinear interaction of intense laser pulses and an inhomogeneous electron-positron-ion plasma.

The nonlinear interaction of an ultraintense short laser beam and an inhomogeneous electron-positron-ion (EPI) plasma is investigated. It is found that the presence of positrons and inhomogeneity results in strong modulational and filamentational instabilities, which induce strong nonlinear interactions between the laser beam and the inhomogeneous EPI plasma. Light beam focusing, filamentation, trapping, and nonlinear interaction between the trapped light spots and the inhomogeneous plasma are observed.

[Effect of vertebral manipulation therapy on vertebro-basilar artery blood flow in cervical spondylosis of vertebral artery type].

Objective: To observe the effect of vertebral manipulation (VM) therapy on vertebro-basilar artery (VBA) blood flow in patients with cervical spondylosis of vertebral artery type (CS-VAT) by transcranial Doppler (TCD) ultrasonic examination.

Methods: One hundred and fifty patients with CS-VAT were randomized into the VM group (n = 100) and the acupuncture group (n = 50), and treated for ten times as one therapeutic course. Changes of the contraction peak, the end-diastolic and average blood flow velocity of VBA before and after treatment in the two groups were observed and compared by TCD.
