BACKGROUND AND AIMS To test the hypothesis that a peptide-based enteral product was equivalent to a low-fat, free amino acid-based formula in the nutritional and functional recovery of the starved rat. METHODS Sixteen male Wistar rats were starved for 3 days. Then, rats were randomised to a whey protein hydrolysate-based diet or a free amino acid-based(More)
Age-associated low-grade systemic inflammation may contribute to sarcopenia. We hypothesized that skeletal muscle mass and protein synthesis rate would be reduced in old rats exhibiting persistent low-grade inflammation compared to age-matched controls. Male 24-month-old Wistar rats exhibiting a low-grade systemic inflammation for at least one month (LGI(More)
The objective of this work was to determine the effects of starvation and refeeding on growth, nutritional recovery and intestinal repair in starved rats. Male Wistar rats, weighing 200 g, were starved for 3 d, then refed a soy-based diet for another 3 d. Normally fed rats were given the same diet and used as controls. The variables assessed were as(More)
Bovine milk protein fractions that enable modification of the protein composition and amino acid profile of infant formulas to mimic those of human milk have recently become available. To determine the effects on protein quality and mineral bioavailability of replacing casein by beta-casein and of whey protein isolate by alpha-lactalbumin, 4 groups of(More)
The objectives of the present study were to determine the splanchnic extraction of glutamine after ingestion of glutamine-rich protein ((15)N-labeled oat proteins) and to compare it with that of free glutamine and to determine de novo glutamine synthesis before and after glutamine consumption. Eight healthy adults were infused intravenously in the(More)
The aim of the work was to resolve whether glutamine and arginine supplemented diets affect plasma and tissue (muscle, liver and intestinal mucosa) glutamine concentrations, as well as glutaminase and glutamine synthetase specific activities. The trial was performed in growing rats fed 10% protein diets for 3 weeks. Protein sources were: whey proteins (W);(More)
