Glia-derived axonal growth inhibitory proteins limit functional repair following damage to the adult cen- tral nervous system （CNS）. Nogo proteins, myelin-as- sociated glycoprotein （MAG）, oligodendrocyte myelin glycoprotein （OMgp） and B lymphocyte stimulator （BLyS）, are 4 inhibitors that commonly interact with the neuronal receptor, Nogo receptor-1 （NgR1）, lead- ing to inhibition of axonal growth. Here, we demon- strate that lateral olfactory tract usher substance （LOTUS） binds to NgR1 and blocks the binding of all four ligands to NgR1, resulting in the suppression of axonal growth inhibition induced by these NgR1 li- gands. LOTUS allows neurons to overcome NgRl-me- diated axonal growth inhibition, raising the possibility that LOTUS may be useful in future therapeutic ap- proaches as an endogenous potent inhibitor of NgR1 for promoting neuronal regeneration.

The present study focuses on the prediction of acoustic absorption performance of a perforated plate with air jets by theoretical calculations. In addition, we experimentally measured the flow rate, internal pressure, acoustic pressure, and transfer function using an acoustic impedance tube. The normal incidence absorption coefficient was calculated from the measured transfer function using transfer function methods. We investigated the influences of background air space, flow velocity, thickness, aperture rate, and aperture diameter of a perforated plate on the acoustic absorption characteristics. The frequency characteristics of the acoustic absorption coefficient showed a maximum value at a local frequency. As the background air space increased, the peak frequency of acoustic absorption characteristics decreased. As the flow velocity passing through the apertures increased, the peak level of the acoustic absorption coefficient also increased. The theoretical results agreed well with the experimental ones qualitatively.
