The influence of different copper and zinc contents in rations on blood serum concentrations in dependence on feeding (Groups A and B) and lactation (Lactation 1 and 2) was tested in a feeding trial with 60 German Holstein cows. All animals received a diet based on maize and grass silage ad libitum. 30 cows received a concentrate supplemented with copper and zinc as recommended (Group A), where...

OBJECTIVE To evaluate the serum levels of zinc and copper in epileptic children during the long-term treatment of anticonvulsant drugs and correlate this with healthy subjects. METHODS A hospital-based group matched case-control study was conducted in the Department of Pediatrics, Faculty of Medicine, Zagazig University, Zagazig, Egypt between November 2013 and October 2014. Ninety patients a...

The blood serum copper level and the phonation start were investigated in sixteen male subjects with developmental stuttering (mean age = 25.8 years). A statistically significant decrease in blood serum copper level was revealed in the stutterers under study. The differences between their mode and mean values and that of the control group were 4.6 mumol/l and 3.1 mumol/l, respectively. The nega...

Aim. To determine trace element status and aetiologic factors for development of trace elements deficiencies in children with iron-deficiency anaemia (IDA) aged 0 to 3 years. Contingent and Methods. 30 patients of the University Hospital, Pleven, Bulgaria-I group; 48 patients of the Sumy Regional Child's Clinical Hospital, Sumy, Ukraine-II group; 25 healthy controls were investigated. Serum con...

Iron-copper interactions were described decades ago; however, molecular mechanisms linking the two essential minerals remain largely undefined. Investigations in humans and other mammals noted that copper levels increase in the intestinal mucosa, liver and blood during iron deficiency, tissues all important for iron homeostasis. The current study was undertaken to test the hypothesis that dieta...

A dysfunction in copper homeostasis seems to occur in Alzheimer's disease (AD). We previously evidenced that an excess of non-ceruloplasmin-copper (NCC) correlated with the main functional, anatomical as well as cerebrospinal markers of the disease. Aim of our study was to investigate ceruloplasmin isoforms as potential actors in this AD copper dysfunction. Our data show that AD patients have c...

Oral squamous cell carcinoma (OSCC) is one of the most common malignant tumors. Its incidence is rated as one among the highest in the world and the use of tobacco in various forms is increasingly associated with the cause of OSCC. Levels of serum copper and iron was estimated and compared among subjects with tobacco habits and healthy controls. OSCC patients were categorized according the toba...

background: there have  been  several studies  done  on the role of metals in the occurrence  of multiple sclerosis (ms) disease, but their roles have not been confirmed yet. because of the lack of information on this issue, this study compared  the  serum  level  of  copper and zinc in ms patients with their levels in a control group. methods: this  was  an  analytical,  cross-sectional  study...

Introduction: Multiple sclerosis (MS) is one of the most common neurologic disorders. It appears that in addition to the common risk factors, there may be other factors, such as serum level of trace elements, which affect the development or course of the disease. The aim of this study was to evaluate the serum levels of iron, zinc and copper in patients with MS and compare them with the control...
