The aims of this study were to (1) determine the activity profiles of a large sample of English FA Premier League soccer players and (2) examine high-intensity running during elite-standard soccer matches for players in various playing positions. Twenty-eight English FA Premier League games were analysed during the 2005-2006 competitive season (n=370),(More)
The tumorigenicity of two coal tar mixtures was compared to that of benzo[a]pyrene after 2 years of feeding. Mixture 1, a composite of coal tar from seven coal gasification plant waste sites, was fed to female B6C3F1 mice (48 mice per group) for 2 years at doses of 0.0, 0.01, 0.03, 0.1, 0.3, 0.6 and 1.0%. Mixture 2, which was composed of coal tar from two(More)
Male and female (840 each) BALB/cStCrlfC3Hf/Nctr mice were given 0, 7, 14, 28, 55, 110 and 220, and 0, 7, 19, 38, 75, 150 and 300 ppm, respectively, of 4-aminobiphenyl in their drinking water. Necropsies on killed animals were performed at 13, 26, 39, 52 and 96 weeks on dose. Dose-related neoplasms were angiosarcomas, bladder urothelial carcinomas and(More)
Fischer 344 rats were given 10, 40, 600, 1200 or 2400 ppm sulphamethazine (SMZ) in the diet to determine the toxicity and potential carcinogenicity of SMZ. There were 225 rats of each sex in the control groups and 135 of each sex in each dose group. Animals were killed after 3, 12, 18 or 24 months of continuous dosing. Body weights, feed consumption,(More)
We allocated 110 DBA/2NNia mice of either sex to one of two feeding regimens: ad libitum (AL) or food restriction (FR) to 60% of the amount consumed by the AL group. The mice were examined at 3, 6, 9, 12, 18, and 24 months (at 3 months, only AL mice were examined). During the remaining periods approximately equal numbers (n = 10) of mice of both sexes and(More)
Large numbers of female BALB/c StCrlfC3Hf/Nctr mice were exposed for up to 33 months to low doses of 2-acetylaminofluorene (2-AAF) under controlled conditions. The study design consisted of sacrifice intervals, life span, and discontinued dosing groups. Two separate and distinct endpoints, that is urinary bladder neoplasms and liver neoplasms, resulted in 2(More)
Fumonisin B1 is a mycotoxin produced by Fusarium moniliforme, a fungus that infects corn and other grains in the U.S. Fumonisin ingestion causes a variety of effects including equine leukoencephalomalacia and porcine pulmonary edema, and has been associated epidemiologically with human esophageal cancer. Fumonisin B1 produces growth inhibition and increased(More)
Longevity, body weight, and age-specific neoplasia were determined in 1,064 B6C3F1 mice as part of a coordinated study of food restriction (FR). Restricted animals were offered 60% of the diet consumed by the ad libitum (AL) group. Longevity data were derived from a set of 56 animals of each sex from each diet group, which were examined whenever dead or(More)
