A prospective multi-centric study was conducted to determine if iron-chelating agent deferiprone also chelates zinc. Twenty four-hour urinary zinc levels were compared in multiply transfused children with thalassemia major not receiving any chelation therapy (Group A, n = 28), those receiving deferiprone (Group B, n = 30) and age and sex-matched controls of subjects in Group B (Group C, n = 29)...

Nephrogenic systemic fibrosis (NSF) has been associated with the administration of gadolinium-based contrast agents in patients with severely impaired renal function (SIRF), endstage renal disease (ESRD), or acute renal failure (ARF). Since the vast majority of these patients do not get NSF, it is highly likely that patient factors play a role in its development. Although "free" or dechelated g...

This communication presents the pH-dependent chelation of Zn(2+) ions with the imidazole groups of poly(1-vinylimidazole) (PVIm) and DNA polyion complex formation with the zinc-chelated PVIm (PVIm-Zn) via chelated Zn(2+) ions. The resulting PVIm-Zn/DNA complexes exhibit no significant cytotoxicity and show outstanding gene expression.

In a systematic effort to identify a potent anticancer agent, we synthesized 15 oxovanadium(IV) complexes and examined their cytotoxic activity against 14 different human cancer cell lines. The oxovanadium compounds included mono and bis ancillary ligands of 1,10-phenanthroline (phen) [VO(phen), VO(phen)2, VO(Me2-phen), VO (Me2-phen)2, VO(Cl-phen), VO(Cl-phen)2, VO(NO2-phen), VO(NO2-phen)2], 2,...

a series of new heteroleptic chelated copper(ii) complexes that encompass n,n-dibezyl substituted derivative of ethylenediamine (x-diamine) and acetylacetonate (acac) were prepared.  the ir and electronic absorption spectra and the molar conductivity of the complexes are presented and discussed.  the molar conductivity values of the complexes in different solvents reveals a predominance of elec...

The presented study aimed at investigating the effect of foliar application of amino acids and nano particles and chelated iron on photosynthetic pigments and yield of potato. To this end a factorial experiment was carried out in the form of randomized complete block design with three replications in 2013, in the Research Field of Natural Resources Institute in Damavand, Iran. The first factor ...

In the crystal structure of the title compound, [Ir(C(17)H(10)NO)(2)(C(5)H(7)O(2))], the Ir(III) atom is O,O'-chelated by the acetyl-acetonate group and C,N-chelated by the 2-aryl-naphth[1,2-d]oxazole groups. The six-coordinate metal atom displays a distorted octa-hedral geometry.
