A 57-year-old man and a 45-year-old woman presented with cerebral abscesses. Diffusion-weighted magnetic resonance (MR) imaging and conventional MR imaging clearly showed the different stages of the course of the brain abscesses. As the abscess matured, the signal intensity of the center gradually increased to the typical high value with a low apparent(More)
OBJECTIVES The aortic augmentation index (AI) and aortic pulse wave velocity (PWV) are known to be indicators of arterial stiffness. However, it is not clear whether aortic AI and PWV reflect aortic stiffness in similar ways. We investigated the relationship between aortic AI and PWV by measuring them directly using a catheter technique. DESIGN AND(More)
The aim of this study was to analyze visual search strategies of baseball batters during the viewing period of the pitcher's motion. The 18 subjects were 9 experts and 9 novices. While subjects viewed a videotape which, from a right-handed batter's perspective, showed a pitcher throwing a series of 10 types of pitches, their eye movements were measured and(More)
Characterization of cardiac MYPT2 (an isoform of the smooth muscle phosphatase [MP] target subunit, MYPT1) is described. Several features of MYPT2 and MYPT1 were similar, including: a specific interaction with the catalytic subunit of type 1 phosphatase, delta isoform (PP1cdelta); interaction of MYPT2 with the small heart-specific MP subunit; interaction of(More)
This study analyzed the visual behaviors of soccer players while they kicked with the inside of the foot, which involved near and far aiming skills. Participants (N = 8) were required to step forward and kick a ball to hit a target. The top three scorers were defined as the High-score group, and the three low scorers were defined as the Low-score group.(More)
This study analyzed visual search strategies of soccer players in one-on-one defensive situations on the field. The 8 subjects were 4 experts and 4 novices. While subjects tackled an offensive player for possession of the ball, their eye movements were measured and analyzed. Statistically significant differences between the visual search strategies of(More)
This paper is concerned with realization of a new kind of three-legged walking machine. The proposed robot has neither coxa joint nor knee joint, so the three legs are just rigidly fixed to each other. Instead of pursuing elaborated joint mechanism for the coxa, we equipped it with two actuators and a pair of weights, so that it can generate torque about(More)
