In an attempt to evaluate the background levels of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), non-ortho, mono-ortho and indicator polychlorinated biphenyls (PCBs) in people living in an urban (Athens) and a rural (Kozani) area of Greece, blood serum and mother milk samples were analyzed. Analytical results are reported(More)
Copper(II) complexes with the non-steroidal antiinflammatory drug mefenamic acid in the presence of aqua or nitrogen donor heterocyclic ligands (2,2'-bipyridine, 1,10-phenanthroline, 2,2'-bipyridylamine or pyridine) have been synthesized and characterized. The crystal structures of [(2,2'-bipyridine)bis(mefenamato)copper(II)], 2,(More)
Food intake is the main source of exposure to dioxin-like compounds for humans. The results of a surveillance programme on polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) and co-planar polychlorinated biphenyls (co-PCBs) in 77 food samples from the Greek market and producers are presented. The study included the analyses of milk and dairy(More)
INTRODUCTION It has been shown recently that platelet indices like mean platelet volume (MPV), platelet size deviation width (PDW) and platelet-to-large-cell ratio (P-LCR) are helpful in the discrimination between hyperdestructive thrombocytopenia like idiopathic thrombocytopenic purpura (ITP) and hypoproductive thrombocytopenia (HT). The aim of the study(More)
Cobalt(II) complexes with the non-steroidal anti-inflammatory drug mefenamic acid in the presence or absence of nitrogen donor heterocyclic ligands (2,2'-bipyridine, 1,10-phenanthroline or pyridine) have been synthesized and characterized with physicochemical and spectroscopic techniques. The experimental data suggest that mefenamic acid acts as(More)
Cobalt(II) complexes with the non-steroidal anti-inflammatory drug naproxen in the presence or absence of nitrogen-donor heterocyclic ligands (pyridine, 2,2'-bipyridine or 1,10-phenanthroline) have been synthesized and characterized with physicochemical and spectroscopic techniques. The deprotonated naproxen acts as monodentate ligand coordinated to Co(II)(More)
INTRODUCTION Hemorrhagic tendency in patients with myelodysplastic syndrome (MDS) is mainly attributed to thrombocytopenia. However, platelet function in these patients has not been thoroughly investigated. AIM The aim of our study is to evaluate platelet function in patients with primary MDS. METHODS Platelet function was studied with aggregometry in(More)
We investigate the problem of information theoretically secure communication in a line network with erasure channels and state feedback. We consider a spectrum of cases for the private randomness that intermediate nodes can generate, ranging from having intermediate nodes generate unlimited private randomness, to having intermediate nodes generate no(More)
We design polynomial time schemes for secure message transmission over arbitrary networks, in the presence of an eavesdropper, and where each edge corresponds to an erasure channel with public feedback. Our schemes are described through linear programming (LP) formulations, that explicitly select (possibly different) sets of paths for key-generation and(More)
