The interaction of copper oxide nanoparticles and copper ions and proteinase K from Tritirachium album Limber has been investigated employing UV spectroscopy and kinetics measurements. The aim of this study was to evaluate the effect of nanoparticles of CuO for proteinase K. In this paper we compare the effect of copper oxide nanoparticles with the effect of copper ions on proteinase K sta...

introduction: there have been many reports and papers on deficient, normal and high levels of copper in patients with thalassemia major. the aim of this study is to evaluate copper status in a series of more than 300 patients with thalassemia major and determine the degree of copper deficiency or excess. methods: three hundred and seventy patients with thalassemia major over 5 years of age were...

the Sol–gel nanocomposite coatings have been investigated for copper metal as a potential replacement for the hazardous and banned hexavalent chromate conversion coatings. TiO2–CdO nanocomposite thin films were deposited on copper using the sol–gel method. The sol-gel coatings were prepared using a sol obtained by the hydrolysis and condensation of tetra-o-butyl titanate. They were doped with c...

conclusions co-occurrence of pbc with wd is rare, which can cause diffusely intrahepatic copper deposition. early liver biopsy and genetic testing are necessary for the diagnosis. the combination of ursodeoxycholic acid with zinc and sodium dimercaptopropane sulfonate is effective. introduction both primary biliary cirrhosis (pbc) and wilson’s disease (wd) can cause copper retention in the live...

Background & Aims of the Study:  Soil and water pollution to heavy metals is a serious threat for environment and human health. Finding an effective way for refining water from these metals is very important. The aim of this study was modifying electrospun polymeric nano fibers and studying its efficiency for copper ion omission in water solutions. Materials & Method...

BACKGROUND It is well known that some trace elements such as zinc and copper play a significant role in many forms of hair loss. However, the effect of zinc and copper in the pathogenesis of hair loss is still unknown. OBJECTIVE The purpose of this study is to evaluate the zinc and copper status in each of four types of hair loss. METHODS A study was carried out with 30 health controls and ...

Sedimentary Copper mineralization has been observed in Monj and Jolany locations in Bavanat (Sanandaj – Sirjan metamorphic belt). According to current study, the host rocks for copper mineralization in this area are green sandstones, generally in subarkose and arkose groups. Age of these sandstones is middle Jurassic. Copper mineralization is observed in two forms, sulfides form including chalc...
