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)
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)
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)
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)
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)
Diagnosis of nervous system disease is greatly aided by functional assessments and imaging techniques that localize neural activity abnormalities. Electrophysiological methods are helpful but often insufficient to locate neural lesions precisely. One proposed noninvasive alternative is magnetoneurography (MNG); we have developed MNG of the spinal cord(More)
We performed exercise thallium-201 myocardial scintigraphy in 32 patients with angina pectoris to study the incidence of perfusion defects, who had no significant organic stenosis on coronary angiography. None of them had myocardial infarction or cardiomyopathy. Thallium-201 myocardial scintigraphy and 12-lead ECG recording were performed during supine(More)
