OBJECTIVE To assess the impact on children's health of translating an evidence-based national intervention trial (Child and Adolescent Trial for Cardiovascular Health [CATCH]) to low-income elementary schools with primarily Hispanic students. DESIGN An untreated, matched control group design with repeated dependent pretest and posttest samples was used.(More)
The objectives were to determine the effects of packaging atmosphere and injection-enhancement on tenderness, sensory traits, desmin degradation, and display color of different beef muscles. Longissimus lumborum (LL; n = 12 pairs), semitendinosus (ST; n = 12 pairs), and triceps brachii (TB; n = 24 pairs; 12 from the same carcasses as the LL and ST and 12(More)
Hens of two moderately inbred White Leghorn stocks, known to differ significantly in escape and avoidance behavior, were compared for productivity traits, nervousness, and feather loss when housed four or eight per cage at densities of 348 (high), 464 (medium), and 580 (low) cm2/bird. Differences were found between stocks in sexual maturity, egg production(More)
OBJECTIVE To determine efficacy of treatment with a combination febantel-praziquantel-pyrantel product, with or without vaccination with a commercial Giardia vaccine, in dogs with naturally occurring giardiasis. DESIGN Prospective trial. ANIMALS 16 Beagles naturally infected with Giardia duodenalis. PROCEDURES During phase 1, 6 dogs were treated with(More)
The Healthy Youth Places (HYP) intervention targeted increased fruit and vegetable consumption (FV) and physical activity (PA) through building the environmental change skills and efficacy of adults and youth. HYP included group training for adult school site leaders, environmental change skill curriculum, and youth-led FV and PA environment change teams.(More)
BACKGROUND This paper reports the primary outcomes of the Healthy Opportunities for Physical Activity and Nutrition (HOP'N) after-school project, which was an effectiveness trial designed to evaluate the prevention of childhood obesity through building the capacity of after-school staff to increase physical activity (PA) and fruit and vegetable (FV)(More)
R ecent technological advances in molecular biology have provided biologists with an unprecedented glimpse of the genomes of living organisms by allowing global assessment of variation in gene sequences and gene expression. A number of recent reviews have outlined the potential for understanding organisms across scales from genes to ecosystems by applying(More)
Little information is available in the literature on the interrelationships and interactions among pH, aging time, marbling, and maturity on the flavor profile of some beef muscles commonly used for steaks. To investigate these effects on beef flavor, the infraspinatus (top-blade steak) from the chuck clod, the gluteus medius (top-sirloin steak) from the(More)
The thin agar layer (TAL) method was experimentally tested to determine its ability to recover Escherichia coli O157:H7 injured by sodium chloride (NaCl). Cells grown in Brain Heart Infusion broth with 0%, 5%, or 7.5% (w/v) NaCl were spread and spiral plated onto Tryptic Soy agar (TSA), MacConkey Sorbitol agar (MSA), and TSA/MSA TAL combinations. Generally,(More)
