Synthesis, characterization and reactivity studies of a hetero-dicopper complex, particularly towards oxygen reduction are presented. A bischlorido copper(II) trishistidine-type coordination unit is positioned directly above copper porphyrin unit. The close distance between the two fragments secured by rigid xanthene backbone. Surprisingly, dinuclear complex not active unlike earlier published ...

We describe a method to isolate small mononucleated Hodgkin (H) cells from multinucleated Reed Sternberg (RS) cells of Hodgkin lymphoma using the ScreenCell filter device. This filtration-based approach lends itself to future clinical applications in that it enables the separation of H and RS cells from lymph node biopsies, bone marrow aspirates, pleural effusions, and blood, including the isol...

Metal ions are indispensable for ribonucleic acids (RNAs) folding and activity. First they act as charge neutralization agents, allowing the RNA molecule to attain the complex active three dimensional structure. Second, metal ions are eventually directly involved in function. Nuclear magnetic resonance (NMR) spectroscopy offers several ways to study the RNA-metal ion interactions at an atomic l...

An integrated computational method which couples classical molecular dynamics simulations with density functional theory calculations is used to simulate the solid-state NMR spectra of amorphous CaSiO(3). Two CaSiO(3) glass models are obtained by shell-model molecular dynamics simulations, successively relaxed at the GGA-PBE level of theory. The calculation of the NMR parameters (chemical shiel...

Growth of the A549 cell line in a perfusion system suitable for use in a magnetic resonance study has been characterized and shown to be stable physiologically and hence appropriate for serial observations. Several methods of monitoring cell growth were compared to assess the behavior of the cells in this system. Comparison between NMR metabolite data and cell growth via cell counting showed th...

Water-soluble multinuclear complexes based on ruthenium 2,2′-bipyridine-6,6′-dicarboxylate (bda) and ditopic bipyridine linker units are investigated in three-component visible light-driven water oxidation catalysis. Systematic studies revealed a strong enhancement of the catalytic efficiency absence organic co-solvents with increasing oligomer length. In-depth kinetic morphological investigati...
