The orientation of mono(1,10-phenanthroline)copper(II), [Cu(phen)]2+, and the ternary complexes with amino acids, [Cu(phen)X(aa)]n+, where X(aa) stands for an alpha-amino acid, has been investigated by electron paramagnetic resonance (EPR) spectra of the complexes on DNA fibers. It has been revealed that these complexes bind to DNA with several different(More)
AIM Prediabetes is an independent risk factor for future stroke. However, no effective treatment has yet been established for the recurrence of stroke in patients with prediabetes. Here we investigated the effects of pioglitazone, a potent peroxisome proliferator-activated receptor-gamma agonist, for the reduction of recurrent stroke in patients with(More)
Multiple sclerosis (MS) is a chronic immune-mediated inflammatory demyelinating disease of the central nervous system. Interferon-β (IFN-β) has been used as the first line therapy for MS treatment in Japan, but patients treated with IFN-β may develop antibodies, known as neutralizing antibodies (NAbs), which abrogate its therapeutic effects. Intramuscular(More)
Anti-aquaporin-4 antibody (NMO-IgG) is used as a diagnostic marker for neuromyelitis optica (NMO). Although the mechanism of spinal cord lesions in NMO has been investigated, that of extensive hemispheric lesions with brain edema remains unclear. Here we report a 36-year-old woman with NMO positive for NMO-IgG, who developed an acute disseminating(More)
The structural maintenance of chromosomes (SMC) family proteins (Smc1-Smc6) typically consist of two coiled-coil domains, an amino-terminal head domain, and a carboxyl-terminal tail domain. Rad50, a component of the Mre11/Rad50/Xrs2 (MRX) complex, has a similar domain structure to the SMC proteins. In Saccharomyces cerevisiae, the MRX complex appears to be(More)
Several works have demonstrated the existence of a link between Mycobacterium avium subsp. paratuberculosis (MAP) and MS in Italy. In this study, we analyzed the serology of MAP in a Japanese population while looking at several markers of MAP. Fifty MS patients, 12 clinically isolated syndrome (CIS) patients, 30 other neurological disorders (OND) patients,(More)
We herein report the case of a 49-year-old man with clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) associated with Legionnaires' disease due to Legionella pneumophila serogroup 2. Past reports suggest that Legionella infection is frequent in cases of MERS-associated pneumonia. Obtaining an early diagnosis of legionella(More)
INTRODUCTION Painless legs and moving toes syndrome (PoLMT) is a rare movement disorder characterized by flexion, extension, abduction, adduction, and torsion of toes in the absence of pain. It is considered a variant of painful legs and moving toes syndrome, which is characterized by similar movements but is accompanied by pain. Although neuropathy, spinal(More)
