The title compound, cis,fac-dichloridotetra-kis(dimethyl sulfoxide)-κ(3)S,κO-ruthenium(II), [RuCl(2)(C(2)H(6)OS)(4)], was obtained from newly synthesized ruthenium complexes of 3-amino-2-chloro-pyridine. The Ru atom has a distorted octa-hedral coordination with two cis-oriented chloride ligands and four dimethyl sulfoxide ligands. Three of the sulfoxide ligands are S-bonded in a fac configurati...

We have developed a liquid material for embolization of arteriovenous malformations that is a mixture of ethylene vinyl alcohol copolymer and metrizamide dissolved in dimethyl sulfoxide. Upon contact with blood, dimethyl sulfoxide rapidly diffuses into the blood and forms an ethylene vinyl alcohol copolymer elastic soft sponge that obstructs both the feeder and the nidus. The material, which is...

Cells of a cloned line of murine virus-induced erythroleukemia were stimulated to differentiate along the erythroid pathway by dimethyl sulfoxide at concentrations that did not inhibit growth. A rise in the number of benzidine-positive normoblasts was accompanied by increased synthesis of heme and hemoglobin and a decrease in the malignancy of the cells. This action of dimethyl sulfoxide, which...

The asymmetric unit of the title compound, [Nd(C(9)H(3)O(6))(C(2)H(6)OS)(2)](n), contains one Nd(3+) ion, one benzene-1,3,5-tricarb-oxy-lic ligand and two coordinating dimethyl sulfoxide mol-ecules. The Nd(3+) ion is coordinated by six O atoms from four carboxyl-ate groups of the benzene-1,3,5-tricarboxyl-ate ligands and two O atoms from two dimethyl sulfoxide mol-ecules. The metal-organic clus...

In the mononuclear title complex, [Zn(C(10)H(8)N(2))(2)(C(2)H(6)OS)(2)](C(24)H(20)B)(2)·C(2)H(6)OS, the Zn(II) ion is coordinated by four N atoms of two bidentate 2,2'-bipyridine mol-ecules and by the O atoms of two cis-disposed dimethyl sulfoxide mol-ecules in a distorted octa-hedral geometry. The S atom and the methyl groups of one of the coordinated dimethyl sulfoxide mol-ecules are disorder...

The presence and accumulation in murine erythroleukemic cells transformed by Friend virus of the erythrocyte membrane-associated protein spectrin has been investigated. Spectrin was present in the uninduced cells and was induced 10- to 20-fold in dimethyl sulfoxide-treated differentiating cells. The intracellular concentration of spectrin reached a peak on the third day of dimethyl sulfoxide tr...
