The effects of increased ruminal supply of butyrate on milk yield, milk composition, and blood metabolites were studied in four lactating cows in a 4 x 4 Latin square design. The basal diet comprised grass silage, hay, and concentrate (34:22:42, DM basis) and was supplemented with isoenergetic VFA infusions (3.58 Mcal/d). A 3:1 molar mixture of acetate and(More)
Tissue distribution, metabolism, and excretion of perfluorodecanoic acid (PFDA) after a single intraperitoneal dose (20 mg/kg) were studied in female and male Wistar rats. PFDA accumulated in the serum and tissues of the rats. In the serum, more than 99% of PFDA was bound by the serum proteins. In the liver, anionic and esterified PFDA were detected.(More)
OBJECTIVE Promoter polymorphisms of the tumor necrosis factor alpha (TNF-alpha) gene are associated with insulin sensitivity and BMI. We investigated whether the effect of the G-308A polymorphism of the TNF-alpha gene on insulin action depends on BMI. RESEARCH METHODS AND PROCEDURES The effects of the G-308A polymorphism on the rates of glucose and lipid(More)
The urinary excretion of perfluorooctanoic acid (PFOA) was studied in male Wistar rats after castration and oestradiol administration as well as in intact females and males. During the first 24 hr females excreted 72 +/- 5% (N = 6) of a single intraperitoneal dose of PFOA (50 mg/kg) in urine whereas the intact males excreted only 9 +/- 4% (N = 6). After(More)
Lipid peroxidation has been shown to be enhanced following exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), but its role in TCDD toxicity is unclear. The present study was undertaken to further elucidate the relations between lipid peroxidation and TCDD lethality. A time course and dose-response experiment in Long-Evans (L-E; LD50 ca. 10(More)
OBJECTIVE The aim of the study was to evaluate the association between previous use of ICS and bone mineral density (BMD) at school age in a cohort followed after early childhood wheezing. METHODS As part of a prospective follow-up study after hospitalization for wheezing at <24 months of age, BMD was measured in 89 children at 12.3 (median) years of age.(More)
Rats were deprived of REM sleep (REMS) for 72 h with the platform method and decapitated in the morning immediately after the deprivation or in the afternoon after having been allowed 5 hours of rebound sleep. The histamine concentrations of the anterior and posterior hypothalamus, the cortex, the hippocampus and the pineal gland were measured, as well as(More)
Perfluoro-octanoic acid [PFO; CF3 (CF2)6 COOH] is a single chain fatty acid with surfactant properties. Thus far the kinetics and toxicity of PFO has not been studied thoroughly. PFO was administered orally 3 mg/kg, 10 mg/kg, and 30 mg/kg to 36 Wistar rats daily for 28 consecutive days. Another 12 animals received 0.5 ml/100 g saline each day. Animal(More)
