Interleukin-8 (IL-8), a monocyte-derived neutrophil chemotactic agent, has a potential role in the regulation of inflammatory responses. The specific receptor for IL-8 has been identified and characterized on the surface of human neutrophils (Samanta, A. K., Oppenheim, J. J., and Matsushima, K. (1989) J. Exp. Med. 169, 1185-1189). The present study demonstrates that at least two sulfhydryl grou...
The reactive cysteines in H-ras are subject to oxidative modifications that potentially alter the cellular function of this protein. In this study, purified H-ras was modified by thiol oxidants such as hydrogen peroxide (H(2)O(2)), S-nitrosoglutathione, diamide, glutathione disulphide (GSSG) and cystamine, producing as many as four charge-isomeric forms of the protein. These results suggest tha...
The crystal structure of the title compound, [Ni(C8H20N4)(C12H8N2)](ClO4)2, has been determined by X-ray diffraction. The Ni(II) ion is six coordinated with four nitrogen atoms of the tetradentate macrocyclic ligand and two nitrogen atoms of the bidentate ligand in a distorted octahedron geometry. The folded tetradentate macrocyclic ligand adopts a configuration having four five-membered chelat...
CuCl has been successfully immobilized on a novel diamide modified SBA-15, and proven to be an efficient heterogenized catalyst for the oxidative carbonylation of methanol to dimethylcarbonate.
Chronic hyperglycemia in type-1 diabetes mellitus is associated with oxidative stress (OS) and sudden death. Mechanistic links remain unclear. We investigated changes in electrophysiological (EP) properties in a model of chronic hyperglycemia before and after challenge with OS by GSH oxidation and tested reversibility of EP remodeling by insulin. Guinea pigs survived for 1 mo following streptoz...
Cobyrinic acid a,c-diamide synthetase from Salmonella typhimurium (CbiA) is the first glutamine amidotransferase in the anaerobic biosynthetic pathway of vitamin B(12) and catalyzes the ATP-dependent synthesis of cobyrinic acid a,c-diamide from cobyrinic acid using either glutamine or ammonia as the nitrogen source. The cbiA gene was cloned, the overexpressed protein was purified to homogeneity...
