Dinuclear iron peroxido complexes are important intermediates for selective oxidation reactions. A detailed kinetic study of the reaction benzoyl chloride (BzCl) with a dinuclear non-heme cis end-on complex ligand EtHPTB (N,N,N′,N′-tetrakis[(N-ethyl-2-benzimidazolyl)methyl]-2-hydroxy-1,3-diamino-propane) had been performed. The starting complex, can be obtained either by iron(II) O2 or instead,...

Dinitrogen (N2) complexes of technetium (99Tc) are rare, and only two examples have been reported. To complement this important class also for 99Tc, different pincer-type 99Tc were studied to assess their abilities coordinating dinitrogen. The reactions the 99TcIII complex [99TcCl3(PPh3)2(NCCH3)] with pincer ligands PNPtBu PyrPNPtBu respectively gave [99Tc(PNPtBu)Cl2] [99Tc(PyrPNPtBu)Cl3], firs...

UNLABELLED Naturally acquired immune regulation amongst family members can result in mutual regulation between living related renal transplant donor and recipients. Pretransplant bidirectional regulation predisposed to superior renal allograft outcome in a CAMPATH-1H protocol. We tested whether Rhesus macaques, a large animal model of choice for preclinical transplant studies, share these immun...

A series of six novel mononuclear, binuclear and linear one-dimensional (1D) compounds of copper(II) with chloranilic acid (3,6-dichloro-2,5-dihydroxybenzoquinone, H2CA) is prepared and a design strategy for the preparation of such complexes is discussed. Four described compounds are linear 1D coordination polymers [Cu(CA)]n, whereas another two involve a binuclear and a mononuclear, Cu2(CA)3 a...

background: umbilical cord blood (ucb) is an alternative source of hematopoietic stem cell transplantation (hsct), used in leukemia treatment. cd26+ cells, a fraction of cd34 positive cells, are a major population of ucb cells which negatively regulate the in vivo homing and engraftment of hscs. cd26 is highly expressed in various cells such as hscs, immune cells, fibroblasts, and epithelial ce...

In ferritin, iron is stored by oxidative deposition of the ferrous ion to form a hydrous ferric oxide mineral core. Two intermediates, formed during the initial stages of iron accumulation in apoferritin, have been observed previously in our laboratory and have been identified as a mononuclear Fe3(+)-protein complex and a mixed-valence Fe2(+)-Fe3(+)-protein complex. The physical characteristics...

The immune system is very complex, it involves the integrated regulation and expression of hundreds of proteins. To understand in greater detail how the human host defence immunomodulatory peptide LL-37 interacts with innate immunity, a systems approach was pursued. Polychromatic flow cytometry was employed to demonstrate that within human peripheral blood mononuclear cells, CD14+ monocytes, my...

Split-thickness pig skin was transplanted on severe combined immunodeficient mice so that pig dermal microvessels spontaneously inosculated with mouse microvessels and functioned to perfuse the grafts. Pig endothelial cells in the healed grafts constitutively expressed class I and class II major histocompatibility complex molecules. Major histocompatibility complex molecule expression could be ...

Two new cobalt(II) complexes with an unsymmetrical bidentate ligand, 2-(1,4,5,6-tetrahydropyrimidin-2-yl)-6-methoxyphenol (H2mthp), were synthesized and crystallographically characterized. Tetra- hexa-coordinate mononuclear selectively obtained by adjusting the stoichiometry of base. The coordination geometry hexa-coordinated complex was severely distorted from ideal octahedron, due to NO5 envi...

SIMPRE is a fortran77 code which uses an effective electrostatic model of point charges to predict the magnetic behavior of rare-earth-based mononuclear complexes. In this article, we present SIMPRE1.2, which now takes into account two further phenomena. First, SIMPRE now considers the hyperfine and quadrupolar interactions within the rare-earth ion, resulting in a more complete and realistic s...
