Abstract The complexes of selected radionuclides relevant for nuclear medicine (In III , Bi Lu Ac and in addition La comparative purposes) with the octadentate (6,6?-((9-hydroxy-1,5-bis(methoxycarbonyl)-2,4-di(pyridin-2-yl)-3,7-diazabicyclo[3.3.1]nonane-3,7-diyl)bis(methylene))dipicolinic acid) ligand, H 2 bispa have been studied by density functional theory calculations modelling both isolated...

Lundgren, D. G. (Syracuse University, Syracuse, N.Y.) and J. J. Cooney. Chemical analyses of asporogenic mutants of Bacillus cereus. J. Bacteriol. 83:1287-1293. 1962.-Bacillus cereus ATCC 4342 and three temperature-sensitive asporogenic mutants were compared regarding some basic cellular components and response to metals in a synthetic medium. The mutants sporulate when cultured at 28 C but are...

The reaction of Co(NO(3))(2)·3H(2)O with pyridine-2,6-dicarboxylic acid and 3,5-dimethyl-1H-pyrazole in a 1:1:3 molar ratio affords the title complex, [Co(C(7)H(3)NO(4))(C(5)H(8)N(2))(3)]·H(2)O. The Co(II) atom is coordinated by one pyridine-2,6-dicarboxyl-ate chelating ligand and three 3,5-dimethyl-1H-pyrazole ligands in a distorted octa-hedral geometry. Hydrogen-bonding interactions involving...

The title compound, (C(3)H(7)N(6))(2)[Zr(C(7)H(3)NO(4))(3)]·4H(2)O or (tataH)(2)[Zr(pydc)(3)]·4H(2)O (tata is 2,4,6-triamino-1,3,5-triazine and pydcH(2) is pyridine-2,6-dicarboxylic acid), was obtained by reaction between pydcH(2), tata and zirconyl chloride octa-hydrate in aqueous solution. In the structure, the Zr(IV )atom is nine-coordinated by three (pydc)(2-) groups, resulting in an anioni...

The reactions of N1,N2-Di-boc-1,2,4-triaminobutane with bridged dicarboxylic acids afford the corresponding bis-amides from which – after removal of the Boc groups – bis(N,N′-bidendate) ligands H2NCH2CH(NH2)(CH2)2NHCO-X-CONH(CH2)2CH(NH2)CH2NH2 can be obtained. New examples are the reactions of the triaminobutane with pyridine-2,6-dicarboxylic acid, with phenylene-1,4-diacetic acid, with terepht...

We evaluated the ability of the combination disk test (CDT) and the Modified Hodge Test (MHT) to discriminate between various carbapenemase-producing Pseudomonas aeruginosa isolates (KPC, n = 36; metallo-β-lactamase (MBL), n = 38) and carbapenemase non-producers (n = 75). For the CDT, the optimal inhibitor concentrations and cut-off values were: 600 μg of 3-aminophenylboronic acid (APB) per dis...
