indium is a heavy metal belonging to group iiia. it is used as a radioimaging and chemotherapeutic agent in diagnosis and also in the treatment of cancers. it is believed that indium may interfere with iron metabolism and reduce cell growth in cancer tissue. the present report was established to study the binding of iron and indium to apo-transferrin (apo-tf) and to identify amino acids involve...

Cobalt(II) has been utilized as an external paramagnetic (1)H NMR probe for the study of the structure of dendrimers that possess specifically located metal recognition sites. The hyperfine-shifted (1)H NMR signals of the Co(II) complexes of several 2,6-diamidopyridine-containing dendrimers have been fully assigned by means of 1D and 2D NMR techniques, including NOE difference, EXSY, COSY, and ...

aim : evaluation of biological characteristics of 13 identified proteins of patients with cirrhotic liver disease is the main aim of this research.   background : in clinical usage, liver biopsy remains the gold standard for diagnosis of hepatic fibrosis. evaluation and confirmation of liver fibrosis stages and severity of chronic diseases require a precise and noninvasive biomarkers. since the...

Metal binding proteins play many important roles in a broad range of biological processes. Characterization of metal binding proteins is important for understanding their structure and biological functions, thus leading to a clear understanding of metal associated diseases. The present study is the first to investigate the effectiveness of magnetic microspheres functionalized with metal cations...

neutral bidentate n-o type complexe of vo(ii) has been synthesized through condensation of dpenicillamine,(d-h2pen), with bis(acetylacetonate)- oxovanadium(iv),[vo(acac)2], at neutralmedium . the established schiff base(no type) complex was characterized on the basis of ir andmass spectroscopy techniques.besides,d-h2pen binding behavior to[vo(acac)2] has been studiedin thermodynamic viewpoint u...

In this study the binding abilities of 1,3-calix[4]biscrown-6 (L) toward Ba2+ and Ca2+ have beenestablished in methanol by spectrophotometric measurements at 25±0.1 °C and 0.01 M ionicstrength, and with using Specfit computer program; stability constants for 2 : 1, metal : ligandcomplexes has been estimated

Porophyrins and their metal derivatives are strong DNA binders with association constant of  to  . Some of these compounds have been used for the radiations sensitization therapy of cancer and are targeted to interact with cellular DNA. Binding of porphyrins to DNA changes the expectral and other physic chemical characteristic of porphyrins, The mode of binding can be extracted from inspection ...
