The title salt, C(16)H(18)N(6)O(2) (2+)·2ClO(4) (-)·2H(2)O, was obtained unintentionally as a major product in the reaction of Zn(ClO(4))(2)·6H(2)O with the N',N'(2)-bis-[(1E)-1-(2-pyrid-yl)ethyl-idene]ethanedihydrazide (H(2)L) ligand. The (H(4)L)(2+) cation lies across a centre of inversion. The pyridiniumimine fragments of (H(4)L)(2+) adopt syn orientations. Intra-molecular N-H⋯N and N-H⋯O hy...
Alzheimer's disease (AD) is increasingly becoming one of the greatest medical challenges. Due to the social and financial burden of AD, detection of AD in its early stages is a topic of major research interest. Thus, emergence of well-validated screening methods for fast detection of AD in the early stages would be of great importance. It is now recognized that the homeostasis and serum bioavai...
T-cell-mediated hypersensitivity to metal cations is common in humans. How the T cell antigen receptor (TCR) recognizes these cations bound to a major histocompatibility complex (MHC) protein and self-peptide is unknown. Individuals carrying the MHCII allele, HLA-DP2, are at risk for chronic beryllium disease (CBD), a debilitating inflammatory lung condition caused by the reaction of CD4 T cell...
evaluation of the geochemistry and hydrochemical quality of bam salt dome located in southern iran, was conducted in this study. two composite samples from salt units were collected and analysed by xrd and xrf to determine their mineral and elemental compositions. water samples were also collected from the only spring in the area and analysed for major anions, cations and some toxic elements. t...
HE WATER quality characteristics and some heavy metals cations (Fe, Mn, Zn, Cu and Pb) of Damietta estuary and in front of Mediterranean coastal shoreline were evaluated through four successive cruises (February 2008 to November 2008). Twelve sites were selected from the two sectors. The results obtained showed that serious deterioration of quality of water at Damietta estuary compared with Med...
In this paper we analyze the consequences of considering risk-augmented speci cations of the relationship between spot and forward rates. Previous parametric speci cations such as the GARCH-M provided disappointing results possibly due to the high degree of persistence of the estimated process for conditional volatility. We propose a more exible semiparametric approach where a nonparametric est...
