Amyotrophic lateral sclerosis is a fatal neurodegenerative disease characterized by progressive motoneuron loss. Redistribution of transactive response deoxyribonucleic acid-binding protein 43 from the nucleus to the cytoplasm and the presence of cystatin C-positive Bunina bodies are considered pathological hallmarks of amyotrophic lateral sclerosis, but(More)
STUDY DESIGN A retrospective analysis of prospectively collected data from consecutive patients undergoing transcranial electrical motor-evoked potential (TCE-MEP: compound muscle action potentials) monitoring during cervical spine surgery. OBJECTIVE.: To divide the warning threshold of TCE-MEP amplitude changes on the basis of origin into the spinal tract(More)
STUDY DESIGN A retrospective cohort study. OBJECTIVE The aim of this study is to investigate the preoperative factors for postlaminoplasty kyphotic deformity in cervical spondylotic myelopathy (CSM) patients without preoperative kyphotic alignment focused on the cervical sagittal balance. SUMMARY OF BACKGROUND DATA After laminoplasty (LAMP), appropriate(More)
OBJECTIVE To measure neuromagnetic evoked fields in the lumbar spinal canal. METHODS Using a newly developed superconducting quantum interference device (SQUID) fluxmeter, neuromagnetic fields of 5 healthy male volunteers were measured at the surface of the lower back after stimulation of the tibial nerves at the ankles. For validation, we inserted a(More)
This paper investigates dynamic source imaging of the spinal cord electrophysiological activity from its evoked magnetic field by applying the spatial filter version of standardized low-resolution brain electromagnetic tomography (sLORETA). Our computer simulation shows that the sLORETA-based spatial filter can reconstruct the four current sources typically(More)
BACKGROUND We previously reported the usefulness of neuromagnetic recordings for the diagnosis of disorders in peripheral nerves or the spinal cord. However, there have been no reports on incomplete conduction block of the spinal cord, which is clinically common in conditions such as cervical myelopathy. Here, we estimated the usefulness of measuring spinal(More)
The objective of the present study was to investigate the differences between coronary hyperresponsiveness without ischemia and vasospastic angina in an ergonovine provocation test using multivariate analysis. We have sometimes experienced a more than 50% narrowing response of vascular diameter without ischemia in a coronary response to ergonovine. We(More)

Physiological role of the adrenal medulla was evaluated in the rat with special reference to the age. The adrenal medulla of Wistar-Imamichi male and female rats was enucleated (AdMx) or sham-operated at 3 or 12 weeks of age. Blood pressure was determined by the tail-cuff method. Systolic blood pressure in immature- and adult-AdMx rats increased(More)
The cause of sex differences in the pressor response to l-adrenaline in adult rats (Tomori, 1986) was further examined using normal and castrated adult rats. Blood pressure was determined by the tail-cuff method. A prolonged elevation of blood pressure in male rats shown after an injection of l-adrenaline (50 micrograms/kg, s.c.) was almost completely(More)
STUDY DESIGN This is a retrospective observational single-center study. OBJECTIVES To compare anterior decompression and fusion (ADF) and laminoplasty (LAMP) for the treatment of cervical spondylotic myelopathy (CSM) patients with large anterior compression in terms of clinical and radiologic outcomes. SUMMARY OF BACKGROUND DATA We have reported that(More)
