In this study we investigated the effects of competing trace metals and Ca2+ on Cd(II), Pb(II), and Cu(II) complexation by humic acid extracted from groundwater in Orange County, California. Two types of titration experiments were conducted, those using a single metal and those in which the humic acid had been preequilibrated with a competing metal (either a trace metal or Ca2+). The labile met...

A new trinuclear Cd (II) complex [Cd3(L)6(2,2-bipyridine)3] [L = N-phenylsulfonyl-L-leucinato] has been synthesized and characterized by elemental analysis, IR and X-ray single crystal diffraction analysis. The results show that the complex belongs to the orthorhombic, space group P212121 with a = 16.877(3) Å, b = 22.875(5) Å, c = 29.495(6) Å, α = β = γ = 90°, V = 11387(4) Å, Z = 4, Dc= 1.416 μ...

background: coeliac disease (cd) is characterized by malabsorption resulting from inflammatory injury to the mucosa of the small intestine by an inappropriate immune response to dietary gluten proteins. the aim of this study was to assess the prevalence of cd in our endoscopy unit by taking routine duodenal biopsies during upper gi endoscopy. materials andmethods: nine hundred and thirteen pati...

a new tris-chelate cd(ii) complex, [cd(dadmbtz)3](clo3)2 has been successfully synthesized and characterized by ir, 1h, 13c nmr spectroscopy, elemental analysis and single crystal x-ray determination. the thermal behavior, uv-vis and fluorescence spectra of compound were studied. in reaction with dadmbtz, cadmium (ii) forms a tris-chelate complex with nearly c3 symmetry for coordination polyhed...

BACKGROUND Invasive techniques are still required to distinguish between uncomplicated and complicated forms of CD. METHODS We set out to investigate the potential use of novel serum parameters, including IL-6, IL-8, IL-17, IL-22, sCD25, sCD27, granzyme-B, sMICA and sCTLA-4 in patients diagnosed with active CD, CD on a GFD, Refractory coeliac disease (RCD) type I and II, and enteropathy assoc...

In the title compound, [CdCu(2)(C(12)H(11)N(2)O(5))(2)(H(2)O)(3)]·2H(2)O, the Cu(II) atoms are in a square plane of N(2)O(2) atoms contributed by the tetra-dentate Schiff base trianion. The Cu(II) atoms are coordinated by one phenolate O atom, one imine N atom, one amido N atom and one carboxyl-ate O atom. The Cd(II) atom is connected via the carboxyl-ate groups, forming a heterotrinuclear Cu(I...

In the binuclear title compound, [Cd(2)(C(2)H(3)O(2))(4)(C(12)H(7)N(3)O(2))(2)], the Cd(II) cations are linked by carboxyl-ate O atoms into a four-membered Cd(2)O(2) rhombic ring with a Cd⋯ Cd separation of 3.7515 (5) Å. Each Cd(II) atom is seven-coordinated by a bidentate 5-nitro-1,10-phenanthroline (5-NO(2)-phen) ligand and two bidentate acetate anions, one of which also acts as a bridge link...
