BACKGROUND Cerebrovascular diseases are very common in hemodialysis (HD) patients. Silent cerebral infarction (SCI) has not been investigated in HD patients although it may be a significant risk factor for cerebrovascular diseases. HYPOTHESIS Chronic renal failure may be an independent risk factor for SCI and cerebrovascular diseases. METHODS Cranial(More)
BACKGROUND Although plasma concentrations of brain natriuretic peptides (BNP) increase in hemodialysis (HD) patients as well as patients with cardiovascular diseases (CD), the clinical significance of BNP in HD patients has yet to be elucidated. In this study, we investigated the pathophysiological significance of BNP in HD patients. METHODS Plasma BNP(More)
It is well known that plasma brain natriuretic peptide (BNP) concentration is elevated in cardiovascular diseases such as congestive heart failure. However, although it has been reported to increase in hemodialysis (HD) patients, little is known about plasma BNP in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). Plasma BNP(More)
The variation in electromyographic output of twelve trigeminal muscles of the rabbit was studied to test the hypothesis that they are under the control of a small number of independent neural factors. Jaw muscle electromyograms (EMGs) of eight animals were recorded in 95 chewing sequences, each consisting of 40-75 chewing cycles. The within-sequence(More)
BACKGROUND It is well known that plasma atrial natriuretic peptide (ANP) is an indicator of extracellular fluid volume expansion and that plasma ANP is considered to be a marker for setting the proper dry weight of HD patients. Although the plasma ANP is a prognostic predictor of cardiac death, the prognostic role of ANP in HD patients has yet to be(More)
31 Chapter 1 Earth Science Multi-Scale Simulator for the Geoenvironment (MSSG), which is a coupled non-hydrostatic atmosphere-ocean-land model, has been developed in the Earth simulator Center. Outline of MSSG is introduced and characteristics are presented. In MSSG development procedure, impact of CIP-CSLR schemes is explored and of turbulence on cloud(More)
Since 1991, we have used 32 extensively porous-coated femoral stems with cylindrical distal cross-section for revision of failed cemented stems. At an average follow-up of 4 years, one stem had been re-revised due to a periprosthetic femoral fracture, but no aseptic loosening has been observed. The average postoperative Harris Hip Score was 84 points.(More)
While the mortality rate of subarachnoid haemorrhage is very high in haemodialysis (HD) patients, the prevalence of unruptured intracranial aneurysms in HD patients has not yet been elucidated. We performed cerebral magnetic resonance angiography (MRA) on 123 HD patients who did not have symptomatic cerebrovascular disease, and on 52 control subjects. On(More)
A coupled atmosphere-ocean-land model MSSG has been developed in the Earth Simulator Center, which is designed to model multi-scale interactions among the atmosphere, the ocean and the coupled system. In this project of this fiscal year, we focused on introducing computational optimization architecture to the MSSG to be run with maximizing the computational(More)
We investigated the magnitude of various maxillary occlusal forces and the direction in which such forces were propagated. Adult monkeys were anesthetized and forced to occlude on sticks of 3, 5 and 7 mm thickness at the canines, second premolars and second molars. Electrical stimulation was applied to the masseter and temporalis muscles, and measurements(More)
