OBJECTIVE To determine the efficacy and safety of unilateral deep brain stimulation on the posterior subthalamic white matter, including the zona incerta (ZI) and the prelemniscal radiation (PRL), for tremor-dominant parkinsonian patients and to determine the exact location of electrodes that were most effective. METHODS Eight parkinsonian patients with(More)
Proximal tremors are often refractory to nucleus ventrointermedius thalami thalamotomy. Subthalamotomy has been suggested to be effective for treatment of tremor, although this procedure is associated with considerable adverse effects, and has rarely been considered a suitable treatment modality. The authors demonstrate the efficacy and safety of(More)
BACKGROUND We previously discovered spinocerebellar ataxia type 14 (SCA14) in a single Japanese family with an autosomal dominant neurodegenerative disorder characterized by cerebellar ataxia and intermittent axial myoclonus. The latter manifestation is selectively observed in patients with early onset. We mapped the locus to chromosome 19q13.4-qter, but(More)
INTRODUCTION The involvement of glycation in neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis (ALS) was recently indicated. We previously reported the existence of an Amadori product, 1-hexitol-lysine (1-HL), which is formed in the early glycation reaction, in axonal spheroids of the anterior horn(More)
Midkine (MK) is the product of a retinoic acid responsive gene and is a member of a new family of heparin-binding growth factors. Neurotrophic effects of MK were examined using cultured spinal cord and dorsal root ganglion (DRG) neurons derived from fetal mouse. MK, which was added to the culture medium at concentrations of 1-100 ng/ml, promoted survival of(More)
In Japan, there is a low prevalence rate (PR) of multiple sclerosis (MS; 0.8-4.0/100,000) but a relatively high frequency of "optic-spinal form" MS (OS-MS). There have been no intensive epidemiologic frequency studies, however, in over 30 years. We performed a province-wide prevalence study of MS in the Tokachi province of Hokkaido, the northernmost island(More)
OBJECT Tremors, including its proximal component, are often refractory to standard thalamic surgery. In the 1960s the posterior part of the subthalamic white matter was reported to be a promising target in treating various forms of tremor, but was also found to be associated with adverse effects. Advances involving a less invasive method, that is, deep(More)
The Maillard reaction that leads to the formation of advanced glycation end products (AGE) is considered to play an important role in the pathogenesis of Alzheimer's disease (AD). Until now AGE derived from glucose (glucose-AGE) have been mainly investigated, so we established new AGE species derived from alpha-hydroxyaldehydes and dicarbonyl compounds. We(More)
Vitamin D-binding protein (DBP) is known to function as an immunomodulatory factor, as well as the main carrier of vitamin D. We analyzed the frequencies of two polymorphisms (codon 416 and codon 420) in the DBP gene through a case-control study involving 107 Japanese patients with multiple sclerosis (MS) and 109 healthy controls. None of these(More)
We investigated PvuII and XbaI polymorphism in the estrogen receptor gene (ERG) and HLA-DRB1*1501 positivity in 116 conventional multiple sclerosis (MS) patients and 101 healthy controls in a Japanese population. Logistic analysis revealed independent associations of [P] allele in the profiles for PvuII (p=0.0005, adjusted odds ratio (aOR)=3.17) and(More)
