OBJECTIVES Metallothionein (MT) and two forms of superoxide dismutase (SOD), which are dependent on zinc and copper ions, are involved in defense against the same superoxide anion radicals and are present in extra- and intracellular compartments. The aim of our study was to investigate MT concentration and Cu/Zn SOD activity in the plasma and erythrocyte lysate of the non-smoking and smoking sm...

Toxic elements emitted from the Pechenganickel complex on the Kola Peninsula have caused concern about potential effects on local wild food in the border regions between Norway, Finland and Russia. The aim of this study was to assess Ni, Cu, Co, As, Pb, Cd, and Hg concentrations in local wild foods from these border regions. During 2013-2014, we collected samples of different berry, mushroom, f...

transfusion of blood products from an infected person with aids, is meant to infect recipient. blood products such as whole blood, red blood cells, platelets, plasma, frozen blood precipitate, factor viii, factor ix, can be infected with hiv. transmissions from blood factors can be seen in plasma from thousands of donors that were collected in a container and were used to treat hemophilia. bloo...

The objective of this study was to determine the concentrations As, Cu, Fe, and Zn in the livers, gills, and muscles of vobla or Caspian roach, Rutilus caspicus (Yakovlev), and bighead goby, Neogobius gorlap (Iljin), from the Miankaleh wetland. The results showed that metal accumulation in the liver tissues was higher than in the gills and muscles for all metals, and Fe concentration was higher...

Levels of contaminants in fish are of particular interest because of the potential risk to humans consuming them. This paper examines the levels of cadmium, lead, zinc and copper in liver and muscle tissue of Esox lucius and in sediments from the Anzali international wetland in Iran. The wetland is a nursery and feeding habitat for fish species both from the lagoon and the Caspian Sea, which ar...

a simple, highly sensitive, accurate and selective method for determination of trace amounts of cu2+ in water samples was reported. in this paper, isopropyl 2-[(isopropoxy carbothioyl)disulfanyl]ethanethioate (iide) in order to prepare an effective sorbent for the preconcentration and determination of cu. the sorption capacity of isopropyl 2-[(isopropoxy carbothioyl)disulfanyl]ethanethioate (ii...

In the present study, we investigated effects of Cu or Ni additions on precipitation intermetallic phases in heat-resistant aluminum alloy with a ternary composition Al-5Mg-3.5Zn (mol%). The quaternary alloys 1 mol%Cu mol%Ni content were solution-treated at 480 °C and subsequently aged 300 for different periods. Both have slight effect age-hardening these °C. added element partitioned into not ...

A tetranuclear mixed ligand copper(II) complex of a pyrazole containing Schiff base and a hydroxyhexahydropyrimidylpyrazole and copper(II) and nickel(II) complexes of the Schiff base having N-donor atoms have been investigated. A 2 equiv amount of 5-methyl-3-formylpyrazole (MPA) and 2 equiv of 1,3-diamino-2-propanol (1,3-DAP) on reaction with 1 equiv of copper(II) nitrate produce an unusual tet...
