We investigated the time sequence of morphological changes of the spiral ganglion cell (SGC) and auditory nerve (AN) following chronic kanamycin-induced deafness. Guinea pigs were treated with kanamycin by subcutaneous injection at 500 mg/kg per day for 7 days. Histological changes in hair cells, SGCs, Schwann cells and the area of the cross-sectional of(More)
Although existing methods (chemical vapor deposition, mechanical exfoliation, etc.) are available to produce graphene, the lack of thickness control limits further graphene applications. In this study, we demonstrate an approach to precisely thin graphene films to a specific thickness using femtosecond (fs) laser raster scanning. By using appropriate laser(More)
Close homologue of L1 (CHL1) is a transmembrane cell adhesion molecule that is critical for brain development and for the maintenance of neural circuits in adults. Recent studies revealed that CHL1 has diverse roles and is involved in the regulation of recovery after spinal cord injury. CHL1 expression was downregulated in the cerebral cortex, hypothalamus,(More)
