Forty stutterers and 40 nonstutterers were tested for susceptibility to delayed auditory feedback (DAF) while reading passages under amplified delay conditions. Susceptibility to DAF of stutterers was significantly higher than that of nonstutterers. In the nonstuttering group, men were more susceptible to DAF than women, but in the stuttering group, there(More)
PURPOSE The purpose of this study was to identify prognostic markers for chemoradiotherapy (CRT) in T(2-4)M(0) esophageal cancer. EXPERIMENTAL DESIGN We investigated clinicopathological and biological markers in biopsy specimens from 73 T(2-4)M(0) esophageal cancer patients treated with CRT (5-fluorouracil plus cisplatin and 60 Gy of radiation).(More)
BACKGROUND Previously we reported that immunohistochemical examination of p53, bcl-2, glutathione S-transferase-pi (GST-pi), thymidylate synthase (TS) and vascular endothelial growth factor (VEGF) in biopsy samples was a useful method for predicting clinical outcome of gastric cancer patients treated with 5-fluorouracil and cisplatin. Here, we investigated(More)
BACKGROUND The efficacy of systemic chemotherapy against peritoneal dissemination from advanced gastric cancer (AGC) remains unclear, because the peritoneal dissemination was not defined as a measurable lesion in conventional phase II studies. In this study, we evaluated the efficacy and toxicity of sequential MTX and 5FU therapy (MF) in chemotherapy-naive(More)
BACKGROUND Our previous phase II study of 5-fluorouracil (5-FU) and cisplatin (FP) for treatment of advanced gastric cancer showed that strong immunoreactivity for vascular endothelial growth factor (VEGF) is associated with chemoresponse. Patients with four or five of the favorable phenotypes, p53 (-), bcl-2 (-), gluthathione S-transferase pi (-),(More)
The effect of delayed auditory feedback (DAF) was investigated by reciting melodies of three levels of complexity (simple, medium and complex), consisting of five tones and five beats per second. Four normal adult subjects recited these melodies with/pa/under 10 conditions of 0 to 900 ms delay (100 ms step). DAF effect was measured by DAF index(More)
PURPOSE A computer-assisted microvessel analysis system was developed to evaluate correlations between the architecture of biopsy specimen microvessels and the outcome for patients with esophageal cancer treated with chemoradiotherapy. EXPERIMENTAL DESIGN Biopsy specimens from 51 patients with esophageal cancer (T(2-3), any N, M0) treated with(More)

A model of consisting of excitatory and inhibitory processes was proposed for visual evoked potentials (VEPs) from the midline occiput (Oz). On and off stimulation of circular lights subtending 2 degrees and 5 degrees in visual angle were presented with luminance contrast of 1.0, 2.2, and 3.4. The typical triphasic data from a well trained male subject were(More)
Sex difference in susceptibility to DAF (delayed auditory feedback) in oral reading of texts was investigated. Forty adults, 20 males and 20 females with normal speech and hearing abilities, read aloud two kinds of texts, one easy to read and the other difficult, under two conditions, NAF (normal auditory feedback) and DAF. Delays were 150, 200, 300, 400(More)
