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 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)
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)
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)
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)
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)
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)
1. EXTRAWING EXTRAWING is a research and development project, started in February 2010, for novel and attractive representations of results of geophysical and environmental fluid simulations and effective transmission of those results to the general public. The name "EXTRAWING" is a coined acronym consisting of the initial letters of the following words:(More)
4 to 6 years old children were given a card-sorting task in order to measure S's dimensional preference. They were trained a discrimination task to one of the 3 training levels, and were shifted to an intradimensional (ID) or an extradimensional (ED) task. The sorting and discrimination tasks consisted of form and color dimensions "with 2 stimulus values,(More)
