Two incubation trials were carried out with the rumen-simulation technique (RUSITEC). In each trial, four vessels received a diet of grass hay and concentrate (600 and 400 g/kg DM, respectively; diet F), and the other four were fed a diet composed of concentrate and barley straw (900 and 100 g/kg DM, respectively; Diet C). Vessels were given 20 g of the(More)
Adapted, follow-up, probiotic follow-up, toddler, and probiotic toddler infant formulas were subjected to an in vitro enzymatic procedure simulating physiological digestion. The formation and identification of casein phosphopeptides (CPPs) in the milk-based infant formulas were studied using reversed phase high-performance liquid chromatography coupled on(More)
Differentiation therapy provides an alternative treatment of cancer that overcomes the undesirable effects of classical chemotherapy, i.e. cytotoxicity and resistance to drugs. This new approach to cancer therapy focuses on the development of specific agents designed to selectively engage the process of terminal differentiation, leading to the elimination(More)
The ferric binding protein (FbpA) is one of the major proteins regulated by the level of environmental iron in the genus Neisseria. Its conservation in all species of pathogenic Neisseria has been demonstrated, and the possible role that it plays in the iron uptake mechanisms in these bacteria has been postulated. Similar proteins in Haemophilus influenzae(More)
Chick embryos after 48 h of development (day 2) maintained in ovo provide an adequate model to study hormonal influences in early organogenesis in vertebrates. In previous studies at this (prepancreatic) stage of chick embryogenesis we demonstrated not only the presence of an insulin-related material but also insulin receptors and insulin-like growth factor(More)
In this study we have evaluated the supplementation of olive oil with vitamin E on coenzyme Q concentration and lipid peroxidation in rat liver mitochondrial membranes. Four groups of rats were fed on virgin olive, olive plus 200 mg/kg of vitamin E or sunflower oils as lipid dietary source. To provoke an oxidative stress rats were administered(More)
The physiologic function of insulin in early embryonic life is unknown. We have shown that insulin is present in unfertilized eggs and in chick embryos at 2-3 days of development, even before the emergence of the endocrine pancreas. To define insulin's role, we exposed 2-day-old chick embryos to anti-insulin antibodies and followed their development up to(More)
Nutrition may affect the balance between immunity and traits such as reproduction or growth. This study examines the effect of low nutrient availability on immunity indices and lactation in captive Iberian red deer. Twelve hinds and their calves were allotted to a food-restricted (50-60% daily energy requirements) or a control group just after calving. Low(More)
Neisseria meningitidis, when cultured in iron-restricted environments, synthesises new outer-membrane proteins, many of which are necessary for their survival and growth. Some of these proteins e.g. transferrin-binding proteins 1 and 2 (Tbp1 and Tbp2), are required for the acquisition of iron from transferrin and are examples of important iron-regulated(More)
