BACKGROUND Epidemiological and clinical evidence suggests that an increased intake of long-chain n-3 fatty acids protects against mortality from coronary artery disease. We aimed to test the hypothesis that long-term use of eicosapentaenoic acid (EPA) is effective for prevention of major coronary events in hypercholesterolaemic patients in Japan who consume(More)
Microbial sensory rhodopsins are a family of membrane-embedded photoreceptors in prokaryotic and eukaryotic organisms. Structures of archaeal rhodopsins, which function as light-driven ion pumps or photosensors, have been reported. We present the structure of a eubacterial rhodopsin, which differs from those of previously characterized archaeal rhodopsins(More)
OBJECTIVE AND IMPORTANCE Intracranial giant aneurysms have been considered to grow by recurrence of intramural hemorrhage of the aneurysmal wall. However, it remains uncertain whether rupture of giant aneurysms is brought about by the same mechanism that causes the rupture of smaller saccular aneurysms. It is also unclear whether intramural hemorrhage is(More)
Neurofibromatosis (NF), or von Recklinghausen's disease, is an autosomal dominant disorder of both mesoderm and ectoderm dysplasia commonly characterized by numerous neurofibromas and cafe-au-lait spots. However, cerebrovascular diseases associated with NF are rare, and among them occlusive vascular lesions have already been reported in the literature. It(More)
The haloarchaeal phototaxis receptor sensory rhodopsin I (SRI) in complex with its transducer HtrI delivers an attractant signal from excitation with an orange photon and a repellent signal from a second near-UV photon excitation. Using a proteoliposome system with purified SRI in complex with its transducer HtrI, we identified by site-directed fluorescence(More)
IUGR was induced by maternal administration of synthetic thromboxane A2 (STA2) from the 13th day of gestation. Fetuses and neonates showed a markedly significant weight reduction. In E16 IUGR brain, no pathological abnormalities were found, but morphological changes appeared in the cortical plate of E18 IUGR brain. In E20 IUGR brain, ectopic clusters of(More)
In the light-driven proton pump bacteriorhodopsin, proton transfer from the retinal Schiff base to aspartate-85 is the crucial reaction of the transport cycle. In halorhodopsin, a light-driven chloride ion pump, the equivalent of residue 85 is threonine. When aspartate-85 was replaced with threonine, the mutated bacteriorhodopsin became a chloride ion pump(More)
A 39-year-old woman had suddenly onset of headache, aphasia and right hemiparesis. CT scan revealed a mass lesion in the left parieto-temporal lobe. The brain tumor was resected twice. But, heart tumor could not be resected because congestive heart failure progressed rapidly. At last, she succumbed to systemic metastasis at 4 months after the onset of(More)
In this paper we propose a method that multiple mobile robots use tools to accomplish tasks. To give an actual example, the robots can push and manipulate objects by means of a stick and can pull objects by means of string. We classify tools in view of their characteristic and the robots make use of characteristics of tools to accomplish tasks easily and(More)
