BACKGROUND Iron accumulation and inflammation may affect atherosclerosis. This study intended to define a cytokine signature in atherosclerotic claudicants and to determine whether reduction in serum ferritin by phlebotomy influenced this pattern. METHODS Ninety-one subjects with peripheral vascular disease (PVD; mean age, 67 years) were recruited from(More)
1. The abilities of BHA and ascorbic acid to prevent the toxic manifestations of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) were examined in female Sprague-Dawley rats. 2. Rats treated with BHA were partially protected from TCDD-induced lipid peroxidation, inhibition of glutathione peroxidase activity, and losses in liver, thymus and body weights. 3.(More)
This exploratory substudy of The Iron (Fe) and Atherosclerosis Study (FeAST) compared baseline inflammatory markers, including cytokines, C-reactive protein (CRP), and ferritin, in subjects with peripheral arterial disease (PAD) taking statins with subjects with PAD who were not taking statins. Inflammatory markers in the serum of 47 subjects with PAD not(More)
Previous studies have shown that high doses of TCDD induce hepatic lipid peroxidation and inhibit selenium dependent glutathione peroxidase (GSH-Px) activity. The dose dependent effects of TCDD on hepatic lipid peroxidation (malondialdehyde content) and GSH-Px activity were determined. A dose as low as 1 microgram/kg induced hepatic lipid peroxidation and(More)
The present study investigated the influence of dietary omega-3 fatty acid supplementation on the growth of human colon carcinoma xenograft in athymic nude mice. Four diets were fed to evaluate the effect of levels and types of fat on colon tumor growth. Animals were maintained on a standard diet modified by addition of fats containing omega-3 and omega-6(More)
The effects of various levels of dietary iron on hepatic lipid peroxidation (malondialdehyde [MDA] content), reduced glutathione (GSH) and GSH peroxidase (GSH-PX) activity as well as liver and body weights of female rats following TCDD administration were examined. Rats were fed diets containing deficient (6 ppm), normal (35 ppm) and supplemented (120 ppm)(More)
Most research of upper respiratory tract disease (mycoplasmal URTD) in the threatened Mojave Desert tortoise (Gopherus agassizii) has worked under the hypothesis that the pathogen, Mycoplasma agassizii, has a relatively consistent and predictable effect on tortoise populations across their natural range. In contrast, we hypothesized that multiple factors(More)
AIMS Mycoplasma agassizii can cause upper respiratory tract disease in the threatened desert tortoise of the Southwestern United States. Two technical challenges have impeded critical microbiological studies of this microorganism: (i) its small size limits the use of light microscopy for cell counting and (ii) its extremely slow growth in broth and agar(More)
