The aim of this study was to investigate the effect of low-intensity exercise training using belt electrode skeletal muscle electrical stimulation on muscle strength and cardiorespiratory fitness in healthy subjects. Nineteen healthy subjects were allocated into control or intervention groups; in both groups the participants kept regular physical activity(More)
Beta2-glycoprotein I (beta2GPI) is a five-domain protein associated with the antiphospholipid syndrome (APS), however, its normal biological function is yet to be defined. beta2GPI is N-glycosylated at several asparagine residues and the glycan moiety conjugated to residue 143 has been proposed to interact with the Gly40-Arg43 motif of beta2GPI. The(More)
STUDY OBJECTIVE To study the association between computer use and visual field abnormalities (VFA) and to assess whether heavy computer users have an increased risk of glaucoma. DESIGN Cross sectional multicentre study. Subjects and observation procedures: A total of 10 202 randomly selected Japanese workers (mean (SD) age 43.2 (9.8) years) were screened(More)
AIMS The aim of this study was to examine whether percutaneous electrical muscle stimulation (EMS) attenuates postprandial hyperglycemia in type 2 diabetes. METHODS Eleven patients with type 2 diabetes participated in two experimental sessions; one was a 30-min EMS 30 min after a breakfast (EMS trial) and the other was a complete rest after a breakfast(More)
OBJECTIVE Risk models and scores have been developed to predict incidence of type 2 diabetes in Western populations, but their performance may differ when applied to non-Western populations. We developed and validated a risk score for predicting 3-year incidence of type 2 diabetes in a Japanese population. METHODS Participants were 37,416 men and women,(More)
OBJECTIVE The aim of this study was to examine whether or not there is a gender difference in metabolic responses to surface electrical muscle stimulation (sEMS) in type 2 diabetes (T2DM). METHODS Ten men and eight women with T2DM participated in two sessions; in both sessions the subjects were investigated after a breakfast and that in one occasion they(More)
In situ x-ray diffraction measurements were carried out for investigating the liquid structure in the ultrasonic fountain jet to consider the mechanism of the "ultrasonic ethanol separation" reported by Sato et al. [J. Chem. Phys. 114, 2382 (2001)]. For pure liquids (water and ethanol), it was found that the high frequency ultrasound does not affect the(More)
Urinary 8-hydroxydeoxyguanosine (8-OH-dG) and 7-methylguanine (m7Gua) were measured by a column-switching high performance liquid chromatography method as markers of oxidative and methylating DNA damage, respectively. We investigated the associations between urinary 8-OH-dG or m7Gua and various lifestyle and demographic factors, such as age and sex. The(More)
AIM The purpose of the present study is to investigate spatial surface electromyography (SEMG) potential distribution pattern in type 2 diabetes mellitus (T2DM) patients. METHODS Nine T2DM patients and nine age-matched healthy men (CON) performed a sustained isometric knee extension at 10% of maximal voluntary contraction for 120s. Multi-channel SEMG was(More)
PURPOSE To report the performance of glaucoma mass screening with only a visual field test utilizing frequency- doubling technology (FDT) perimetry in general populations. DESIGN Hospital and population-based cross-sectional study. METHODS This study took place in a multicenter setting. One hundred three consecutive glaucomatous patients and 14,814(More)
