ReviewStereotactic radiosurgery and radiation therapy for spinal tumors.
Spinal tumors constitute 15% of all CNS neoplasms. Radiation therapy can be administered for palliation of pain and spinal cord compression. However, the amount of radiation that can be administered is often limited by the tolerance of the spinal cord, especially in cases where prior radiation therapy has been given. ⋯ These are technically demanding procedures and should be performed only when proper equipment and expertise are available. Data on spinal stereotactic radiosurgery and radiotherapy have emerged in recent years. This review summarizes the clinical applications of stereotactic radiosurgery and radiotherapy for spinal tumors.

Evaluation of: Hahn CJ, Hoau-Yan W, Dan-Sung C et al. Altered neuregulin 1-erbB4 signaling contributes to NMDA receptor hypofunction in schizophrenia. Nat. ⋯ Furthermore, NMDA receptors in tissue from schizophrenic patients appeared to be more sensitive to the inhibitory effects of a fixed dose of NRG1. In agreement, the ErbB4-PSD-95-NMDA complex was more tightly coupled in schizophrenic brains and NRG1-mediated stimulation of ErbB4 was markedly enhanced. These findings underscore the importance of NMDA receptors in schizophrenia and support therapeutic strategies aimed at boosting glutamate transmission.
