The compounds in diesel exhaust particles (DEP) that are responsible for vasodilatation were isolated and characterized for the first time. From benzene extract of DEP, 2-methyl-4-nitrophenol, 3-methyl-4-nitrophenl and 4-nitrophenol were isolated, and their vasodilatation activities were confirmed. 3-methyl-4-nitrophenol caused dilatation of rat thoracic artery, and the other two nitrophenols, ...
The present paper describes the functional characterization of two human aryl sulphotransferase (HAST) cDNAs, HAST1 and HAST3, previously isolated by us from liver and brain, respectively [Zhu, Veronese, Sansom, and McManus (1993) Biochem. Biophys. Res. Commun. 192, 671-676; Zhu, Veronese, Bernard, Sansom and McManus (1993) Biochem. Biophys. Res. Commun. 195, 120-127]. These appear to encode th...
the present work is focused on the degradation of 4-chloro-2-nitrophenol in aqueous solution containing nano titanium dioxide, hydrogen peroxide and the combination of nano-tio2/h2o2. the effect of experimental parameters, such as the amount of nano- tio2 concentration of h2o2, initial concentration of 4-chloro-2-nitrophenol and ph on the reaction was investigated. experimental data obtained un...
adsorption of p-nitrophenol by three different activated carbons (f100, s.e.i. and b.d.h.) was carried out at 301 k and at controlled ph conditions. two different adsorption models (langmuir model and freundlich model) were studied and compared. the adsorption capacity of the carbons depends on the point of zero charge (pzc) and surface area of the carbons. adsorption of the solute at higher ph...
