In the hydro-thermally prepared title coordination polymer, [Ni(C(2)H(6)NO(3)S)(2)(C(12)H(10)N(4))](n), the Ni(II) ion and the 1,4-bis-(1H-imidazol-1-yl)benzene ligand occupy special positions on inversion centers. The metal ion shows a slightly distorted octa-hedral coordination geometry, being linked to two N atoms of two 1,4-bis-(imidazol-1-yl)benzene ligands and to two O and two N atoms of ...

The metabolism of sodium 3 alpha,7 beta-dihydroxy-5 beta-cholane-24-sulfonate and sodium 3 alpha,7 beta-dihydroxy-24-nor-5 beta-cholane-23-sulfonate was studied in hamsters. In bile fistula animals these sulfonate analogs of ursodeoxycholic acid were absorbed mainly from the terminal ileum and secreted rapidly into the bile without biotransformation or conjugation. After oral administration, th...

objective(s): this study investigated the protective effect of tanshinone iia sodium sulfonate (tss) on ischemia-reperfusion (i/r) induced cardiac injury, and the underlying mechanism of action. materials and methods:male sprague-dawley rats were subjected to a 30-min coronary arterial occlusion followed by 24 hours' reperfusion. half an hour before the left coronary artery ligation, rats ...

A statistical-mechanical treatment of the solubilization in micelle is presented in combination with molecular simulation. The micellar solution is viewed as an inhomogeneous and partially finite, mixed solvent system, and the method of energy representation is employed to evaluate the free-energy change for insertion of a solute into the micelle inside with a realistic set of potential functio...

In natural gas exploitation, foam drainage, corrosion inhibition and hydrate of wellbore fluid are conventional operations. However, there is often a problem where multiple chemical agents cannot be effectively used together can only separately, resulting in complex production processes. this study, the final integrated formulation was determined: 0.1% sodium alpha-olefin sulfonate (AOST) + 0.3...

Background. The use of sodium polystyrene sulfonate in decreasing serum potassium has recently been questioned due to the lack of documented effectiveness. Methods. A retrospective cohort analysis of all hospitalized patients who received sodium polystyrene sulfonate over four months was performed. The change in serum potassium was noted over a period of 24 hours. Patients who received any othe...
