A dehydroabietyl derivative 2 bearing a 2-(2'-hydroxyphenyl)benzimidazole unit was synthesized and its sensing behaviors toward metal ions were investigated by UV-Vis and fluorescence spectroscopy methods. In THF solution, compound 2 exhibited excellent selectivity for CuII over miscellaneous other metal ions including CrII, MnII, CoII, NiII, ZnII, CdII, AlIII, MgII, PbII, HgII, NaI, LiI and KI...

A method was developed for the separation of CdII, PbII, PtII, CoII, NiII, BiIII, CrII, CuII and HgII bis(2-hydroxyethyl)dithiocarbamate (HEDTC) complexes by micellar electrokinetic capillary chromatography. The complexes were formed by pre-capillary reaction of the metal ions with an excess of the ligand and then separated using a 100 mm borate buffer (pH 9.2) containing 4% methanol (v/v), 10 ...

In the polymeric title compound, [CdCl2(C6H6N4)] n , the central CdII atom is coordinated by four chloride ligands and two N atoms from a chelating 2,2'-bi-1H-imidazole mol-ecule, leading to a distorted octa-hedral Cl4N2 coordination set. As a result of the μ2-bridging character of the Cl ligands, chains parallel to the c axis are formed, with the chelating 2,2'-bi-1H-imidazole ligands decorate...

Contact-dependent growth inhibition (CDI) systems are widespread amongst Gram-negative bacteria where they play important roles in inter-cellular competition and biofilm formation. CDI+ bacteria use cell-surface CdiA proteins to bind neighboring bacteria and deliver C-terminal toxin domains. CDI+ cells also express CdiI immunity proteins that specifically neutralize toxins delivered from adjace...

Novel triarylazoimidazoles containing strong electron donors (p-NEt2) or acceptors (p-NO2) by the azoaryl group, and their group 12 metal complexes were synthesized fully characterized, including X-ray analysis for several complexes. exhibit red photo-luminescence emission (Φ up to 0.21) in a solution. Moreover, antibacterial activity of was tested against Gram-positive microorganism S. aureus ...

The responses of liver and serum gluta­mate dehydrogenase (CDII; EC 1.4.1.2.), isocitrate (ICDH; 1.1. 1.42) the urea cycle enzyme, ornithine carbamoyltransferase (OCT; 2. 1.3.3) to dietary lima bean haemagglutinin (lectin) were assessed using a total S4 growing rats. GDH ICDH activities in highly significantly (P < 0.001) eleva­ted by haemagglutinin. activi­ties correlated 0.01) with levels ...

Contact-dependent growth inhibition (CDI) is a widespread mechanism of bacterial competition. CDI(+) bacteria deliver the toxic C-terminal region of contact-dependent inhibition A proteins (CdiA-CT) into neighboring target bacteria and produce CDI immunity proteins (CdiI) to protect against self-inhibition. The CdiA-CT(EC536) deployed by uropathogenic Escherichia coli 536 (EC536) is a bacterial...

We present a procedure for recovering the conformal factor of an anisotropic conductivity matrix in a known conformal class, in a domain in Rn with n ≥ 2. The method requires one internal measurement, together with a priori knowledge of the conformal class of the conductivity matrix. This problem arises in the medical imaging modality of Current Density Impedance Imaging (CDII) and the interior...
