Abnormal folding and accumulation of alpha-synuclein is implicated in several neurological disorders including Parkinson's disease. Although alpha-synuclein is a typical cytoplasmic protein, a small amount of both monomeric and aggregated forms is secreted from cells and is present in human body fluids, such as cerebrospinal fluid. Extracellular(More)
Location-based systems for indoor positioning have been studied widely owing to their application in various fields. The fingerprinting approach is often used in Wi-Fi positioning systems. The K-nearest-neighbor fingerprinting algorithm uses a fixed number of neighbors, which reduces positioning accuracy. Here, we propose a novel fingerprinting algorithm,(More)
Among the putative mechanisms, by which extremely low frequency (ELF) magnetic field (MF) may affect biological systems is that of increasing free radical life span in organisms. To test this hypothesis, we investigated whether ELF (60 Hz) MF can modulate antioxidant system in mouse brain by detecting chemiluminescence and measuring superoxide dismutase(More)
Amyloidosis producing insoluble fibrillar protein aggregates is the common pathological feature of various neurodegenerative disorders such as Parkinson's and Alzheimer's diseases in which alpha-synuclein and amyloid beta/A4 protein (Abeta) participate to form Lewy bodies and senile plaques, respectively. To develop a novel analytical tool for amyloidosis,(More)
SCOPE Natural flavanones exhibit cancer preventive and/or therapeutic effects. The objective of this study was to investigate the molecular mechanism underlying the action of the antitumor activity of hydroxyflavanone using the HCT116 colon cancer cell line. METHODS AND RESULTS We investigated the effect of hydroxyflavanones on antitumor activity. We(More)
Recently, injectable dermal fillers have become important alternatives to surgical procedures for the correction of facial wrinkles. Bovine collagen is the first approved material for filler injection, and several studies have shown its efficacy. However, the risk of developing an allergic reaction and xenogenic transmission of bovine spongiform(More)
alpha-Synuclein participates in the Lewy body formation of Parkinson's disease. Elucidation of the underlying molecular mechanism of the amyloid fibril formation is crucial not only to develop a controlling strategy toward the disease, but also to apply the protein fibrils for future biotechnology. Discernable homogeneous granules of alpha-synuclein(More)
The ultimate goal in treating zygomatic complex fracture is to obtain an accurate, stable reduction while minimizing external scars and functional deformity. The present authors present our experiences with a single transconjunctival incision and two-point (inferior orbital rim and frontozygomatic suture) fixation in 53 patients with zygomatic complex(More)
alpha-Synuclein is a pathological component of PD (Parkinson's disease) by participating in Lewy body formation. JC-1 (5,5',6,6'-tetrachloro-1,1,3,3'-tetraethylbenzimidazolyl carbocyanine iodide) has been shown to interact with alpha-synuclein at the acidic C-terminal region with a K(d) of 2.6 microM. JC-1 can discriminated between the fibrillation states(More)
Parkinson disease (PD) is the second most common neurodegenerative disease characterized by a progressive dopaminergic neuronal loss in association with Lewy body inclusions. Gathering evidence indicates that α-synuclein (α-syn), a major component of the Lewy body, plays an important role in the pathogenesis of PD. Although α-syn is considered to be a(More)
