Nuclear medicine bone imaging has been the optimum diagnosis for the detection of bone disorders because the lesion could be detectable before the appearance of symptomatic and radiographic changes. Over the past three decades, (99m)Tc-MDP and (99m)Tc-HMDP have been used as bone scintigraphic agents because of their superior biodistribution characteristics, although they are far from optimal fr...

In the title mononuclear complex, [Zn(C(7)H(4)NO(4))(2)(C(8)H(8)N(2)S)(2)], the Zn(II) atom is coordinated by two N atoms from two 2-amino-6-methyl-1,3-benzothia-zole and by two carboxylate O atoms from two 4-nitro-benzoate ligands, adopting a slightly distorted tetra-hedral coordination geometry. In the crystal, inter-molecular N-H⋯O hydrogen bonds between the amino group of 2-amino-6-methyl-1...

The mononuclear title complex, [Fe(CF3O3S)(C5H7O2)2(C4H8O)] or [Fe(acac)2(OTf)(THF)] (acac = acetyl-acetonate; OTf = tri-fluoro-methane-sulfon-ate; THF = tetrahydrofuran), (I), consists of one six-coordinate Fe(3+) atom in a slightly distorted octa-hedral environment [Fe-O bond-length range = 1.9517 (11)-2.0781 (11) Å]. The triflate ligand was found to be disordered over two sets of sites, with...

background: the rh antigens are expressed as parts of a protein complex in the rbc membrane. this complex is a tetramer, consisting of two molecules of rhag and two molecules of rh proteins. to express rhd in rbc membrane, expression of rhag is essential. this co-expression only occurs in the erythroid lineage. k562 cell line has an erythroid lineage. materials and methods: cord blood was used ...

the formation constants of the species formed in the systems h+ + mo(vi) + histidine and h+ +histidine have been determined at different aqueous solutions of methanol (0 - 45 % v/v) at 25 °c andconstant ionic strength (0.1 mol dm-3 sodium perchlorate), using a combination of spectrophotometricand potentiometric techniques. the composition of the complex species was determined by thecontinuous v...

objective: schizophrenia is a complex widespread neuropsychiatric disorder. this illness encompasses a complex debilitating mental disorder causing illusion, delusion, disturbed relationship, low motivation and decline of emotion. viral infection of the brain including borna disease virus (bdv) may play a role in transient or permanent neurological and behavioral abnormalities. this role of bor...

The synthesis and characterisation of two terpyridine based ruthenium/palladium heteronuclear compounds are presented. The photocatalytic behaviour of the Ru/Pd complex containing the linear 2,2':5',2''-terpyridine bridge (1a) and its analogue the non-linear 2,2':6',2''-terpyridine bridge (2a) are compared together with the respective mononuclear complexes 1 and 2. Irradiation of 1a with visibl...

Water-bound metal (M) complexes play a central role in the catalytic centers of natural systems such as Photosystem II (PSII), superoxide dismutase, cytochrome c oxidase and others. In these systems, electron transfer reactions involving the metal center are coupled to proton transfers. Besides its fundamental interest, comprehension of these reactions and of possible bio-inspired catalytic dev...
