OBJECTIVES To estimate rates of cadmium (Cd) uptake from the digestive tract and changes in Cd in biological specimens after intake of Cd mainly in rice. METHODS Twenty-five young non-smoking Japanese female volunteers (20-23 in age) were recruited and a 20-d experimental study was conducted. With polished rice containing 0.004 ppm and 0.340 ppm of Cd,(More)
The relationship between oxidative stress and carcinogenic metals including nickel and cadmium is a matter of interest. To assess the oxidative stress status of workers exposed to nickel and cadmium simultaneously, we determined urinary excretion of 8-hydroxyguanine (8-OH-Gua), a urinary oxidative stress marker. Our subjects were 66 (64 males and 2 females)(More)
From the perspective of human nutrition, the prevention of age-related macular degeneration (AMD) through diet control is feasible and desirable. We investigated the relationship between serum antioxidants and AMD in the community-dwelling older Japanese eating a typical Japanese diet. In this study, 722 subjects aged 65 years or older (297 males and 425(More)
BACKGROUND The objective of this study was to assess the relation between serum levels of retinol and other antioxidants and hearing impairment in Japanese older adults. METHODS This is a community-based cross-sectional study comprising 762 residents aged 65 years or older in Kurabuchi, Gumma, Japan. We measured serum retinol and other antioxidants(More)
The effects of the substitution of brown rice (Oryza sativa L.; BR) for corn (Zea mays L.) in ensiled total mixed ration (TMR) that had a high proportion of grain on feed intake, lactation performance, ruminal fermentation, digestion, and N utilization were evaluated. Nine multiparous Holstein cows (51 ± 9 d in milk) were used in a replicated 3 × 3 Latin(More)
Seven Holstein cows (BW = 639.4 +/- 28.8 kg, age = 62.6 +/- 6.9 mo, parity = 3.1 +/- 0.4 yr) (mean +/- SE) were used to measure uterine blood flow using a transit time ultrasonic flow meter. Ultrasonic flow probes were implanted (d 218 +/- 4 of gestation) around both uterine arteries (n = 3) or the gravid uterine artery (n = 4) to measure variations in(More)
