Stress can induce preferential engagement of habit learning mediated by the basal ganglia, relative to learning that involves complex spatial associations contributed by the hippocampal formation. We explored in mice the influence that chronic episodes of social stress exert on the selection of cognitive/spatial vs. habit-based learning strategies. Male(More)
Thermal processing of milk is a common practice. As milk is the main source of dietary calcium, this study aimed to assess the effects of overheating milk on calcium availability. Thus, thermally damaged milk (overheated, OH, milk; 3 cycles of sterilization at 116 °C, 16 min) was compared with UHT milk (150 °C, 6s) in 2 types of assays: in vitro and in vivo(More)
Maillard reaction products (MRP) consumption has been related with the development of bone degenerative disorders, probably linked to changes in calcium metabolism. We aimed to investigate the effects of MRP intake from bread crust on calcium balance and its distribution, and bone metabolism. During 88 days, rats were fed control diet or diets containing(More)
Effects of apparent total tract digestible dietary protein [expressed as apparent ileal digestible (AID) Lys in parentheses] from excessive to marginally deficient [110 (7.9), 92 (6.6), 73 (5.3) and 54 (3.8) g/kg DM] and feeding level (FL; 0.80 and 0.95 × ad libitum) upon fractional absorption and retention of Ca and P was studied in 48 purebred Iberian(More)
Conjugated linoleic acid (CLA) is a group of positional and geometric isomers of linoleic acid. The major dietary sources of CLA are meat from rumiants and dairy products. There are also foods enriched in CLA (by modification animal feed or addition of commercial CLA from cartamo oil). However, the major isomer of CLA in natural food is cis-9,trans-11 and(More)
OBJECTIVES To determine women's satisfaction with pregnancy follow-up and to evaluate possible differences among healthcare levels. METHODS Cross-sectional study in women who had given birth in the University Hospital of Salamanca (Spain) between November 2002 and April 2003. Satisfaction was measured by a self-completed questionnaire after delivery. The(More)
Piglet body composition at weaning could be a determinant for pig's viability and may be influenced by factors such as the nutritional management followed during suckling. An experiment was conducted to study whether intermittent suckling (IS) affects body composition at weaning and nutrient and energy retention during a 34-day lactation period in Iberian(More)
Traditionally the effects of dietary Maillard reaction products (MRPs) on food intake and body weight have been described in different studies, but few investigations have been conducted to analyse the main contributors responsible. We studied the effects of long-term consumption of MRPs from bread crust (BC) on rat growth, investigating the efficiency of(More)
INTRODUCTION The school canteen plays today an essential role in child nutrition and for consolidating appropriate eating habits. In Spain, the guidelines for school meals have been established by the NAOS strategy and the Perseus program, and are especially aimed at school children of 6-10 years. However, there is a lack of information on menus offered in(More)
The main objective of this work was to investigate the effects of feeding Lys-deficient diets on muscle biochemical characteristics, particularly intramuscular fat concentration and fatty acid profile, in a fatty (Iberian) and a conventional pig genotype (Landrace × Large White [LDW]) maintained in identical experimental conditions. Performance and plasma(More)
