Objective:To assess the impact of a physical activity program on obesity in primary school children.Design:Cluster-randomized controlled trial with 10 intervention and 10 control schools.Participants:A total of 1044 children, mean age 9.4 years (s.d.=0.7) at baseline, of the Province of Cuenca, Spain.Intervention:Recreational, non-competitive physical(More)
The effects of the sporulation temperature in the range 20-45 degrees C on the D and z values of three isolates of Bacillus cereus (ATCC 4342, 7004 and 9818) were investigated. The strains were found to differ in their response. Higher D100 values (around 10-fold) were obtained with isolates 4342 and 9818 when the sporulation temperature increased from 20(More)
Three hundred and six Limousin young bulls (7±1months of age, initial body weight 273±43kg) were used to evaluate the effect of crude glycerine supplementation on animal performance, carcass characteristics and meat quality. Animals were assigned to three different diets: Control (0% of crude glycerine), G2 and G4 (2 and 4% of crude glycerine,(More)
An experiment was conducted to investigate the effect of dietary levels of crude protein (CP), close to the range used commercially and to the European Commission recommended values, on the nitrogen (N) balance, ammonia (NH(3)) emission and pollutant characteristics of the slurry from growing and finishing pigs. Three feeding programmes with different CP(More)
AIMS To provide data on the effects on culture temperature and physiological state of cells on heat resistance of Enterococcus faecium, which may be useful in establishing pasteurization procedures. METHODS AND RESULTS The heat resistance of this Ent. faecium (ATCC 49624 strain) grown at different temperatures was monitored at various stages of growth. In(More)
We describe 10 cases born to nondiabetic mothers who presented with severe spondylocostal dysostosis (SCD) associated with other anomalies, identified among 20,526 malformed liveborn infants from the Spanish Collaborative Study of Congenital Malformations (ECEMC). We analyze the associated malformations in the 10 cases with severe SCD, as well as in all(More)
Patients with amyotrophic lateral sclerosis (ALS) experience progressive and irreversible paralysis as a result of the continued loss of motor neurons, which leads to death in less than five years. To date, there is no treatment that can change the progression of this disease. Bone marrow stem cells have shown neural regenerative and neural repairing(More)
New alternatives are necessary if the environmental impact linked to intensive poultry production is to be reduced, and different litter handling methods should be explored. Among these, acidifying amendments added to poultry litters has been suggested as a management practice to help reduce the potential environmental effect involved in multiple flock(More)
A procedure was developed for cloning and characterizing genes that encode proteins with nuclease activity in the Streptococcus pneumoniae [pLS1] host/vector system. Clones are screened for nuclease activity by a DNase colony assay and the nucleases that they produce are characterized by detection of enzyme activity after sodium dodecyl(More)
