The effect of the sulfonate analogues of ursodeoxycholic acid, namely sodium 3 alpha,7 beta-dihydroxy-24-nor-5 beta-cholane-23-sulfonate (norUDC-SO3Na) and sodium 3 alpha, 7 beta-dihydroxy-5 beta-cholane-24-sulfonate (UDC-SO3Na), on biliary lipid secretion was studied in bile fistula rats. During intravenous infusion of the two sulfonate analogues, bile flow and biliary lipid secretion were sti...
chemical flooding, especially alkaline/surfactant/polymer flooding, is of increasing interest due to the world increasing oil demand. this work shows the aspects of using alkaline/surfactant/polymer as an enhanced oil recovery method in the porous media having a high dead-end pore frequency with various dead-end pore parameters (such as opening, depth, aspect ratio, and orientation). using glas...
A novel and simple spectrophotometric method for the determination of tiopronin with sodium 1,2-naphthoquinone-4-sulfonate (NQS) is established in this paper. The detailed mechanism is proposed and discussed. It is based on the fact that tiopronin can catalyze the reaction between sodium 1,2-naphthoquinone-4-sulfonate and hydroxyl ion to form 2-hydroxy-1,4-naphthoquinone in a buffer solution of...
