Copper, iron, manganese and zinc were measured in breast milk samples collected from 82 healthy lactating mothers. Samples were collected from day of delivery to 7 days postpartum. Zn was analysed by flame atomic absorption spectrometry and the other elements by electrothermal atomic absorption spectrometry. Copper concentrations remained constant. Iron(More)
Plasma selenium (Se), zinc (Zn) and copper (Cu) levels and antioxidant metalloenzymes, glutathione peroxidase (GPX) and superoxide dismutase (SOD), were studied in 17 patients on maintenance hemodialysis (HD) (group I), 14 uremic patients (group II) and 14 healthy subjects (group III). Plasma Se levels and erythrocyte GPX were significantly lower in the HD(More)
OBJECTIVE To assess relationships between energy, nutrient and food intakes, alcohol consumption, smoking status and body mass index (BMI), and serum concentrations of beta-carotene, alpha-tocopherol, vitamin C, selenium and zinc. METHODS Data on health status, alcohol consumption, smoking habits, anthropometric data and biochemical measurements were(More)
A simultaneous determination of retinol, alpha-tocopherol and beta-carotene in serum by high-performance liquid chromatography is described. Total analysis time is 13 min. A reversed-phase (Ultrasphere ODS, 5 microns) column is used with a mobile phase of acetonitrile-methanol-dichloromethane (70:10:20, v/v/v) and a flow-rate of 1.2 ml/min. Retinol is(More)
OBJECTIVE The general objective of the Etude du Viellissement Arterial (EVA) program is to follow vascular aging and the decline in cognitive functions at the cerebrovascular level longitudinally over a 4-year period. One of the specific objectives of this EVA study is to examine epidemiologically the relationship between the markers of oxidative stress(More)
BACKGROUND Limited observational evidence suggests lower antioxidant concentrations in individuals with the metabolic syndrome (MetS); few randomized controlled trials have addressed the effect of multiple antioxidants on the risk of MetS. OBJECTIVE The objective was to examine the effect of antioxidant supplementation for 7.5 y on the incidence of MetS(More)
BACKGROUND An enhancing effect of short-chain fructooligosaccharides (scFOSs) on intestinal calcium absorption has been shown in animals and in some short-term human studies. However, the long-term effect of scFOSs on calcium absorption in humans is still unknown. OBJECTIVE We investigated the long-term effect of a moderate daily dose (10 g) of scFOSs on(More)
Selenium status decreases in elderly populations. Cardiovascular diseases are the primary cause of death in the French elderly, and selenium may protect against cardiovascular diseases. The present work aims to evaluate the relationships between cardiovascular-related risk factors and plasma selenium variability in an elderly population during a 9-year(More)
A prospective epidemiological study was carried out over 1 year to evaluate vitamin B complex dietary intake and status in Cuba, 2 years after the Cuban neuropathy epidemic of 1993. Of the 199 healthy middle-aged men selected, 141 completed the study. Volunteers were followed up every 3 months for 1 year. Dietary intake and status of thiamin, riboflavin,(More)
OBJECTIVE To investigate the relationship between selenium status, thyroid Volume and gland echostructure. DESIGN Cross-sectional. METHODS In 792 men (45-60 Years) and 1108 women (35-60 Years) from the SU.VI.MAX study, thyroid Volume and gland echostructure were determined ultrasonographically. At baseline, thyrotropin, free thyroxine, selenium, zinc,(More)
