plant growth is often limited by low levels of soil micronutrients such as copper (cu), ‎especially in calcareous salt-affected soils of arid and semiarid regions. the aim of this ‎work was to investigate individual and combined effects of salinity and cu on growth, leaf ‎relative water content (lrwc), cell membrane permeability, lipid peroxidation, and total ‎phenolic content (tpc) of rosemary...

The objective of this study was to develop a numerical model for the prediction of temperature distribution, effective plastic strain distribution, and especially material flow in friction stir welding of copper plates. The DEFORM-3D software was used by incorporating a lagrangian incremental formulation. Threedimensional results of the material flow pattern which were extracted using the po...

BACKGROUND/AIMS The differential diagnosis of Wilson Disease (WD) is challenging, especially in children, because liver copper levels may also increase in other chronic liver diseases with bile stasis. The aim of this study is to determine urine and liver copper cut-off values to differentiate WD from other chronic liver diseases (non-WD, NWD) in children. MATERIALS AND METHODS Seventy-six pa...

This study was performed in order to determine the relative and combined effects of ethanol, a low protein diet and steroid treatment on bone, muscle, liver, and urinary and faecal excretion of zinc, copper and iron in 64 rats divided into eight groups treated following the Lieber-DeCarli liquid diet technique, with and without dexamethasone, 1 mg/l. Steroids showed a lack of effect on liver zi...

Acinetobacter baumannii is an important emerging pathogen that is capable of causing many types of severe infection, especially in immunocompromised hosts. Since A. baumannii can rapidly acquire antibiotic resistance genes, many infections are on the verge of being untreatable, and novel therapies are desperately needed. To investigate the potential utility of copper-based antibacterial strateg...

Menkes disease (MD) is a rare genetic neurodegenerative disorder. It is caused by a mutation in the ATP7A gene, which codes for the copper-transporting ATPase in the cell organelles. Dysfunction of many copper-dependent enzymes results in low concentrations of copper in some tissues and accumulation of copper in others. We report on a boy that at the age of 2 months presented with encephalopath...

We used stable water suspensions of copper oxide particles with mean diameter 20 nm and of particles containing copper oxide and element copper with mean diameter 340 nm to assess the pulmonary phagocytosis response of rats to a single intratracheal instillation of these suspensions using optical, transmission electron, and semi-contact atomic force microscopy and biochemical indices measured i...
