The trace element content of clinkers (and possibly of cements) can be used for the qualitative identification (i.e. manufacturing factory). Several hundred clinker sorts have been analysed (by replicated quarterly samples, collected from all Hungarian cement factories as well as from factories of 8 foreign countries) to determine their Mg, Sr, Ba, Mn, Ti, Zr, Zn and V content. The first 6 elem...
Background and Aim: Diabetes is a metabolic disorder, in which either there is no sufficient insulin in the body or the available insulin is not capable of acting properly. Defining the effects of trace elements can help to make use of these elements in control or preventing diabetes. Materials and Methods: Forty-eight Wistar male rats were equally divided into eight groups. Three different ...
background: there are studies that indicated dyshomeostasis of oxidant/antioxidant and trace elements in breast cancer patients, but the data regarding the status of these parameters in various stages of breast cancer are limited. the aim of this study was to highlight the status of these biochemical factors in various stages of breast cancer. methods: fifty-eight breast cancers patients partic...
the present study was conducted to evaluate the effect of parenteral supplementation of cobalt, copper and iron in late pregnancy on ewe hematology parameters and lamb vigour. twenty ewes were allocated to one of two groups (n=10). in the test group, on day 120 ofpregnancy, cobalt, copper and iron were injected at a dose of 0.1 ml/kg bw (fercobsang, france, cobalt gluconate 5 mg/100 ml, copper ...
heavy metals in high concentrations in soils are potential health risk for humans, animals, and plants. soil samples were collected in five replicates from 20 points with four land use including: roads, refineries, residential area (sadra town), and farmland. heavy metals were determined using flame atomic absorption (analyticjena), while dtpa was chosen as trace elements extractor. in this stu...
ABSTRACT BACKGROUND: PIXE (Particle Induced X-Ray Emission) is a suitable method for the analysis of biological samples in which heavy trace elements are contained in light matrix elements. It is very important to know which factors or probably elements act as initial seed and lead to growing the sands. The goal of this study was to compare the relative values of Fe/K, Cu/K and Zn/K for gallst...
concentrations of elements (as, co, cu, ni, mo, pb, v, cd, cr and zn) are studied in the surface sediments of bakhtegan lake, northwest of nyriz city, iran, to assess metal contamination. the average abundance order of trace elements content in bakhtegan lake sediments is cr>ni> v> zn> cu> co> as> pb> mo>cd. the comparison of trace elements concentration in bakhtegan lake sediments with toxicol...
