The purpose of this study was to clarify the characteristics of the physiological response that occurs while walking in water and on land at an exercise intensity based on the rating of perceived exertion (RPE) in elderly men. Nine elderly men ranging from 66-70 years of age participated in this study as subjects. The actual trials consisted of walking for(More)
The use of deep seawater (DSW) in thalassotherapy has begun in Japan. To clarify the health effects of DSW on the human body, we investigated the changes in plasma lactate and pyruvate concentrations, or subjective judgment scores, after bathing at rest in 9 healthy young men. Subjects were immersed for 10 minutes in DSW, surface seawater (SSW), and tap(More)
OBJECTIVES Deep seawater (DSW) utilization technology has been developed for the fields of medicine and health, among others. To clarify the health effects of DSW as compared with surface seawater (SSW) or tap water (TW), we investigated the changes of immune cell distribution of the peripheral blood, or subjective judgment scores, after hot water bathing.(More)
A low flicker-noise CMOS mixer for multi-standard receiver in 130-nm CMOS is presented. The mixer which consists of an AC coupled passive mixer and a low noise buffer amplifier with CMFB achieves a low flicker noise corner frequency of 50 kHz. Dual-mode DC offset cancellation circuits are used to compensate the mixer DC offset for multi-standard(More)

In order to ascertain the possibility that platelet serotonin uptake may occur during storage of platelet concentrates (PC) at 22 degrees C with agitation, the high-performance liquid chromatographic procedure was applied to determine serotonin uptake by platelets. Studies at 22 degrees C showed that platelets stored for 4 days exhibited a significant(More)
Experiments were carried out to investigate the effects of anti-asthma drugs on cGMP levels. In vitro, theophylline (5 X 10(-4) M) increased basal and 5-hydroxytryptamine stimulated cGMP formation by platelets (p less than 0.05) while salbutamol and prednisolone produced no change. No significant differences were found in urine cGMP levels in healthy(More)
A discrete-time filter for GSM/WCDMA/WLAN with area reduction technique is presented. The discrete-time filtering is suitable for pass band selection and anti-alias filtering. Reduction of large switched-capacitor area is a key issue for the filter. In this paper, we propose the retiming technique and the optimization of unit capacitor to reduce the number(More)
There is a close relationship between the rate of the uterine cervix opening during parturition and the presence or absence of a completely ripened cervix. In order to learn the basic pattern of the ripening of cervix, histological and histochemical studies were performed on the human uterine cervix during pregnancy. It was noted that the collagen bundles(More)
