BACKGROUND Scrapie and bovine spongiform encephalopathy (BSE) belongs to the group of animal transmissible spongiform encephalopathy (TSE). BSE epidemic in the UK and elsewhere in Europe has been linked to the use of bovine meat and bone meals (MBM) in the feeding of cattle. There is concern that pigs, poultry and fish bred for human consumption and fed(More)
Our work on isolated rat intestine aimed at studying the hypothesis that the intestinal transport of manganese was carrier-mediated and, consequently, subjected to saturation. Our results confirm this hypothesis, assessing the concentration of carrier saturation for manganese at 0.5 mM. As this concentration, which may determine self-limitation in the(More)
Extracts of the bilberry fruit have protective effects against retinopathy and vascular complications; therefore, they are important ingredients in food supplements. Recently, there have been several reported cases of adulteration. Thus, to characterize the anthocyanin profile, and the relative percentages of these pigments, this study analyzed bilberry(More)
Cyanidin and its glycosides belong to the anthocyanins, a widespread class of water-soluble plant compounds that are responsible for the brilliant color (red, orange, blue) of fruits and flowers. They are widely ingested by humans as it has been estimated a daily intake around 180 mg, mainly deriving from fruits and red wines. This paper reviews the(More)
OBJECTIVE We investigated the influence of different ratios between casein phosphopeptides and calcium (CPP/Ca) in intestinal lumen on passive Ca transport across the distal small intestine of rats in vitro. METHODS We measured the amounts of passive Ca absorbed across the everted distal small intestine of rats with the use of radioactive 45Ca as tracer.(More)
The restricted diets of patients with chronic renal insufficiency (CRI) can lead to inadequate intake of some vitamins. We studied thiamin, riboflavin and pyridoxine nutritional status of CRI subjects on unrestricted or low-protein diet. Results show that riboflavin status is inadequate even before the beginning of the follow up and worsens with time for(More)
Lutein is a carotenoid present in dark green leafy vegetables and it may be involved in the prevention of several diseases related to oxidative stress. The aim of this study was to evaluate bioavailability of lutein from different food sources (150 g spinach and 200 g broccoli) and a supplement in oil (300 mg VEGEX), all providing about 9 mg lutein. Eight(More)
The purpose of this study was to evaluate the effect of supplementation with procyanidins from Vitis vinifera on markers of oxidative stress. Ten healthy volunteers received a daily dose of 110 mg of procyanidins for 30 days. Fasting venous blood samples were taken before and at the end of the supplementation period and after 7 days of wash-out. The total(More)
The effect of wild blueberry consumption on anthocyanin (ACNs) distribution and metabolism in Sprague-Dawley (SD) rats was investigated. Thirty-two rats were fed for 4 or 8 weeks with a control (C) or a wild blueberry-enriched diet (8%) (WB). Anthocyanin profile in plasma, urine, feces, brain, and liver was evaluated by LC-MS/MS, and significantly increased(More)
50 different food items, including "first courses", main and side dishes, cheese and pork products, have been analysed for proteins, carbohydrates, fats, fiber, thiamin, riboflavin and vitamin A. The results obtained have been compared with the values determined on food samples by means of food composition tables so as to have information about the(More)
