Estrogenic and anti-androgenic activity of nitrophenols in diesel exhaust particles (DEP).
TLDR
Anti-androgenicity is found in all four nitrophenols isolated from diesel exhaust particles (DEP) because these compounds are alkylphenolic derivatives that might mimic hormones. Expand
Usefulness of 11C-Methionine for Differentiating Tumors from Granulomas in Experimental Rat Models: A Comparison with 18F-FDG and 18F-FLT
TLDR
It is suggested that 14C-methionine has the potential to accurately differentiate malignant tumors from benign lesions, particularly granulomatous lesions, providing a biologic basis for clinical PET studies. Expand
Estrogenic activities of chemicals in diesel exhaust particles.
TLDR
It was found that the neutral fraction of the hexane extract of DEP contains dibenzothiophene derivatives, one of which, 4,6-dimethyldibenz Rothiophene, possesses estrogenic activity. Expand
An experimental approach to study the biosynthesis of brominated metabolites by the red algal genus Laurencia.
TLDR
The present study strongly indicates that the use of radiobromine [(82)Br] in combination with the TLC-ARLG method is an effective approach for investigating the biosynthesis of brominated metabolites in Laurencia. Expand
Isolation of nitrophenols from diesel exhaust particles (DEP) as vasodilatation compounds.
TLDR
The compounds in diesel exhaust particles (DEP) that are responsible for vasodilatation were isolated and characterized for the first time and caused dilatation of rat thoracic artery and the other two nitrophenols also showed vasodILatation activities. Expand
Estrogenic and anti-estrogenic activities of two types of diesel exhaust particles.
TLDR
Both type-1 and type-2 DEP possess estrogenic and anti-estrogenic activities, and extracts of both types decreased the activity of estrogen. Expand
Identification of stable cytotoxic factors in the gas phase extract of cigarette smoke and pharmacological characterization of their cytotoxicity.
TLDR
Results show that acrolein and MVK areresponsible for the acute cytotoxicity of the CSE through PKC/NOX-dependent and -independent mechanisms, whereas CPO is responsible for the delayed cytot toxicity of theCSE through a PKC or NOX-independent mechanism. Expand
Separation and Identification of Taxifolin 3- O -Glucoside Isomers from Chamaecyparis Obtusa (Cupressaceae)
TLDR
It was found that the compounds could be distinguished by the use of 1 H- and 13 C-NMR spectral data, including 2D shift correlation. Expand
Improvement of an efficient separation method for chemicals in diesel exhaust particles: analysis for nitrophenols
TLDR
The present method involving an acid-base extraction, in situ derivatization, and GC–MS analysis has shown to be a simple, efficient, and reliable method for the isolation and identification of the chemical substances in DEP. Expand
Increased [18F]2-fluoro-2-deoxy-D-glucose ([18F]FDG) yield with recycled target [18O]water: factors affecting the [18F]FDG yield.
TLDR
Levels of several ionic impurities including Cl- and Ca2+ were significantly higher in the virgin [18O]water than in the recycled water, while significantly larger amounts of organic impurities were detected in the former, Hence, trace amounts of organics were not responsible for the lower [18F]FDG yield.
