Plasma concentrations of copper and zinc and leucocyte concentrations of zinc were measured in mothers during later pregnancy, at delivery, and 8-10 weeks after birth, and plasma concentrations of copper and zinc were measured in their infants at delivery and 8-10 weeks after birth. The 145 infants were either breast fed or fed one of two milk formulas supplying copper at different concentratio...

current study was done to determine the concentration of heavy metals including lead and cadmium and nutrients element copper and zinc in a simple and whole wheat macaroni in the valid different supermarkets in the city of tehran. 254 samples from seven iranian simple macaroni , four foreign simple macaroni and two iranian whole wheat macaroni were purchased consecutively in 3 seasons of 2015. ...

Treatment with oral chelation therapy withD-penicillamine for copper accumulation inWilson disease was first developed in the 1950s, and preemptive treatment became the standard of care for patients.1 An alternative chelating agent, trientine, was developed more than a decade later and has gained more acceptance as first-line treatment due to its safety profile and demonstration of efficacy.2,3...

BACKGROUND Older subjects have a high risk of developing zinc and copper deficiencies. AIM To determine the prevalence of copper and zinc deficiencies in adults aged over 60 years, living in Metropolitan Santiago. SUBJECTS AND METHODS Analyses were performed using anonymous serum samples from older subjects living in Santiago, Chile, who participated in the multicenter project SABE. Of the ...

Metallothionein was purified under anaerobic conditions from livers of human fetuses ranging from 19 weeks gestational age to term. Homogeneous metallothionein obtained in the absence of reducing agents from the soluble fraction of the tissue which contained 24% and 85% of the total liver copper and zinc, respectively, had less than 1 g atom of copper and about 3.1 g atoms of zinc/mol. Extracti...

background: contamination of the environment due to heavy metals is a major concern to human life and the environment. this study was conducted to investigate and quantify the copper and zinc concentrations in industrial estates soil in arak, iran. methods: four industrial estates were considered for the experimental design, including arak 1, arak 2, arak 3, and ghotbe sanaati. for preliminary ...

Background: Pre-eclampsia along with its complications seems to be one of the major causes of maternal morbidity and mortality. Despite numerous studies, the etiology of pre-eclampsia has not yet been fully elucidated. According to recent studies changes in the level of blood trace elements can be an adverse event in human and animal pregnancy. The present study determines whether maternal seru...

A series of studies were conducted to determine the effect of supplemental trace mineral source on growth performance, morbidity, and trace mineral status in growing beef cattle. The first experiment evaluated supplemental trace minerals from sulfate, organic, or hydroxy sources on growth performance and morbidity. Crossbreed beef calves were assigned to 1 of 3 treatments consisting of suppleme...

Cyanidation is the main process for gold and silver recovery from its ores. In this study, a process is proposed to recover copper and cyanide from barren solutions from the Merrill-Crowe cementation process with zinc dust. This technology is based on inducing nucleated precipitation of copper and silver in a serpentine reactor, using sodium sulfide as the precipitator, and sulfuric acid for pH...
