This investigation was undertaken in view of the interest lately aroused in the association of plasma lipids with atherosclerosis. Observations on the antilipemic and anticoagulant activities in man of sodium polyethylene sulfonate, a new drug with heparin-like properties, are presented. Alteration of the serum lipoprotein patterns of these patients observed during the course of the drug admini...

Occurrence of perfluorooctane sulfonate (PFOS) in the tissues of humans and wildlife is well documented. In this study, concentrations and distribution of PFOS, perfluorohexane sulfonate (PFHS), and perfluorobutane sulfonate (PFBS) were determined in samples of surface water, fish and bird blood and livers, and human blood collected in Japan. Notable concentrations of PFOS were found in surface...

In the title complex, [Cd(C(6)H(4)N(3)O(3)S)(2)(C(12)H(8)N(2))(2)]·2H(2)O, the Cd(2+) cation is located on an inversion center and is coordinated by four N atoms from two symmetry-related 1,10-phenanthroline ligands and two sulfonate O atoms from two benzotriazole-7-sulfonate anions, displaying a distorted CdN(4)O(2) octa-hedral geometry. In the crystal, O-H⋯N, O-H⋯O, N-H⋯O, C-H⋯N and C-H⋯O hyd...

The title compound, [Fe(CF(3)O(3)S)(C(36)H(44)N(4))], is an iron(III) porphyrin complex with the trifluoro-methane-sulfonate anion as an axial ligand. The Fe atom is displaced by 0.219 (2) Å toward the trifluoro-methane-sulfonate anion from the 24-atom mean plane of the porphyrin, resulting in a distorted FeN(4)O square-based pyramidal geometry. One ethyl-ene group is disordered over two orient...

Crystal structure of zwitterionic trimethylammoniopropane sulfonate (Z1-Methyl) was determined by single-crystal X-ray diffractometry. Z1-Methyl crystallized in the monoclinic system, space group P2(1), with a = 6.3639(2), b = 10.9237(4), c = 8.1505(4) A, beta = 111.078(2) degrees, V = 528.69(4) A3, Z = 2. An inter-molecular ionic association was observed in the crystal. The shortest distance b...

The inhibitory effect of sodium polyanethol sulfonate (0.05%) upon growth of Neisseria meningitidis was found to be neutralized by adding gelatin (l.1%) to the growth medium. The neutralizing effect was demonstrated in solid medium, as well as in nutrient broth for blood cultures. The findings parallel those of Wilkins and West (6) regarding gelatin neutralization of the inhibitory effect of so...

The title compound, [Fe(CF(3)O(3)S)(C(48)H(36)N(4)O(4))], is a five-coordinate iron(III) porphyrin complex with a trifluoro-methane-sulfonate anion as an axial ligand. The Fe(III) atom is displaced by 0.40 (1) Å towards the trifluoro-methane-sulfonate anion from the 24-atom mean plane of the porphyrin. The average Fe-N(p) distance is 2.044 (2) Å and the Fe-O distance is 2.001 (2) Å.

The imino-diacetic acid component of the title salt, C(4)H(8)NO(4) (+)·C(7)H(7)SO(3) (-), is protonated at the N atom. The cation uses the ammonium group to form hydrogen bonds to the O atoms of two adjacent sulfonate groups. In addition, the carboxylic acid portions of the cation form hydrogen bonds to the sulfonate groups. The hydrogen-bonding inter-actions give rise to a layer structure.

A wide-ranging overview of room temperature phosphorescence in the liquid state (RTPL1) is presented, with a focus on recent developments. RTPL techniques like micelle-stabilized (MS)-RTP, cyclodextrin-induced (CD)-RTP, and heavy atom-induced (HAI)-RTP are discussed. These techniques are mainly applied in the stand-alone format, but coupling with some separation techniques appears to be feasibl...
