The diaqua complex [Pt(2-methylthiomethylpyridine)(OH(2))(2)](2+), Pt(mtp), was synthesized and investigated thermodynamically as well as kinetically. Spectrophotometric acid-base titrations were performed to determine the pK(a) values of the two coordinated water ligands. A low pK(a1) value of 3.15 was observed for the water molecule trans to the pyridine donor, whereas a pK(a2) value of 6.84 ...

the response to methimazole [1-methyl-2-mercapto-imidazole (mmi)] therapy, 10 mg twice daily in 15 patients and propylthiouracil (p tu) therapy, 100mg twice daily in 10 patients with diffuse toxic goiter was evaluated in an area of iodine deficiency (tehran). the mean free t4 index (ft4i) decreased from 22.7± 6.8 (± sd) to 10.8± 2.8 in mmi-treated, and from 25.1± 6.8 to 13.2± 2.1 in ptu-treated...

We introduce a family of proportional surplus division values for TU-games. Each value first assigns to each player compromise between her stand-alone worth and the average worths over all players, then allocates remaining among players in proportion their worths. This contains new egalitarian as two special cases. provide characterizations this values, well single family.

The complete amino acid sequence of elongation factor Tu of Escherichia coli has been established by sequencing overlapping cyanogen bromide and tryptic peptides. Sequence analysis of peptides was done primarily by solid-phase Edman degradation. Elongation factor Tu is a single chain polypeptide composed of 393 amino acids (Mr = 43,225). Its NH2 terminus is blocked with an acetyl group, as dete...

For any given matrix A ∈ Cn×n, a preconditioner tU (A) called the superoptimal preconditioner was proposed in 1992 by Tyrtyshnikov [20]. It has been shown that tU (A) is an efficient preconditioner for solving various structured systems, for instance, Toeplitzlike systems. In this paper, we construct the superoptimal preconditioners for different functions of matrices. Let f be a function of ma...

Altered expressions of mitochondria elongation factor Tu (EF-Tu) have been observed in certain types of cancers, including gastric cancer cell lines, but the impact of the alterations in gastric adenocarcinoma remains unclear. The purpose of this study was to investigate the expression of EF-Tu in gastric adenocarcinoma and to assess its clinical significance. A total of 104 paired resected gas...

This paper makes two claims about non-finite constituents headed by the affixes -tu/-i/-n/-Ø in Basque. First the semantics of these elements in modal contexts indicates that the standard analysis of these constituents as aspectual phrases is incorrect. We argue that -tu/i/-n/-Ø are merged as infinitival markers, which we take to be of category n. In perfective contexts the verb+-tu/-i/-n/-Ø ra...
