BACKGROUND Nutrients such as folic acid and selenium are decreased in dams exposed to ethanol during gestation and lactation, affecting their metabolism, antioxidant balance, and the future health of their progeny. We will study whether the supplementation of the maternal diet with folate and selenium can prevent ethanol-induced oxidative liver disorders in(More)
Ethanol consumption affects maternal nutrition and antioxidant status together with the future health of their progeny. Selenium (Se) is a trace element with antioxidant activity; we will study the effect of ethanol in dams on Se bioavailability, antioxidant balance and gestational parameters. We also will study if a Se-supplemented diet (0.5 ppm)(More)
AIMS Antioxidant system abnormalities have been associated with ethanol consumption. This study examines the effects of chronic ethanol consumption on oxidative balance, including selenium (Se) levels in alcoholic patients with or without liver disease, and if these measurements could be indicative of liver disease. MAIN METHODS Serum Se levels,(More)
Ethanol exposure during gestation and lactation decreases selenium (Se) intake, disrupting body Se balance and inducing oxidative stress in rat offspring. Selenium-supplemented diet (0.5 ppm) was administered to ethanol-exposed (20% v/v) dams during gestation and lactation. When the dams' pups were 21 days old, the pups' levels of the main hepatic(More)
Ethanol consumption affects maternal nutrition, the mothers' antioxidant balance and the future health of their progeny. Selenium (Se) is a trace element cofactor of the enzyme glutathione peroxidase (GPx). We will study the effect of ethanol on Se bioavailability in dams and in their progeny. We have used three experimental groups of dams: control, chronic(More)
Selenium (Se), an essential trace metal, is important in both growth and reproduction and is the constituent of different selenoproteins. The glutathione peroxidase (GPx) family is the most studied as it prevents oxidative stress. Liver oxidation is considered as another mechanism involved in low birth weight. Therefore, in order to ascertain whether GPx is(More)
AIMS The principal aim of this study was to investigate the oxidative effects of chronic ethanol consumption on the functions of the heart and the kidney and the possible modification of this effect by folic acid supplementation. Moreover, in order to find whether this oxidative profile affects cardiovascular function, parameters such as heart rate and(More)
The Ehrlich reaction was optimized to determine pyrrolized phospholipids produced as a consequence of oxidative stress. The procedure consisted of the treatment of the modified phospholipids with p-(dimethylamino)benzaldehyde at a controlled acidity temperature and the spectrophotometric determination of adducts produced. The extinction coefficient of(More)
AIM The aim of this paper is to study the relationship between alcohol, selenium and oxidative stress in breastfeeding rat pups exposed to ethanol during gestation and lactation. We have also studied how a Se-supplemented diet among mothers could prevent different oxidative liver disorders in the pups. METHOD Pups of 21 days were randomized into four(More)
