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)
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)
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)
The content of total and carcinogenic polycyclic aromatic hydrocarbons (PAHs) in Italian foods was measured. The highest levels of PAHs were found in pizza baked in wood-burning ovens and barbecued beef and pork. Relatively high levels were also found in beet greens and squash, apples and bread, fried beef, pork and rabbit, cured meats and chocolate.(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 effect of wild-blueberry consumption on the resistance of H(2)O(2)-induced DNA damage was evaluated in the Sprague-Dawley (SD) rat. Thirty-two, four week-old SD rats were randomly assigned to two groups of sixteen rats each and fed a control diet (C) or a wild-blueberry (WB) diet for four or eight weeks. Following the dietary treatment, plasma(More)
BACKGROUND AND AIMS We have previously reported that wild blueberry (Vaccinium angustifolium)-enriched diets (WB) attenuate aortic adrenergic response through endothelial-mediated pathways. The duration of dietary intervention necessary to induce the positive changes on vasomotor tone has not been studied to date. Thus, our objective was to investigate the(More)
