Zinc electrowinning is performed with the application of a current through insoluble electrodes (Pb-Ag), causing the electrolysis of zinc sulfate, with or without impurities, and zinc deposition on the cathode of aluminum. The impurities can reduce the current efficiency and increase the energy consumption in zinc electrolysis. In this work, the effect of nickel and magnesium on zinc electrodep...

Zinc and magnesium are potent inhibitors of the NMDA receptor complex. Previous reports demonstrated that both zinc and magnesium, like other NMDA receptor antagonists, exhibit antidepressant-like effects in rodent screening tests. Moreover, chronic treatment with antidepressants and electroconvulsive shock increase zinc concentration in the rat hippocampus. The present study examined the effec...

Through the microwave assisted fast synthesis method, Zinc Magnesium Oxide nanocomposite was prepared. Zinc Magnesium Oxide nanocomposite heated at 500oC was used for further structural, optical and antibacterial studies. The Debye Scherrer equation was used to calculate the average particle size of the nanocomposite. The optical characterization of the oxide nanocomposite was carried out by UV...

Many studies suggest the fluctuation of the serum level of zinc and magnesium in diabetic patients compared with healthy individuals and etiological role of these elements in the pathogenesis of diabetes. This study aimed to measure the serum level of zinc and magnesium in three groups of healthy individuals, patients with diabetes, and patients with metabolic syndrome and relationship of these...

background: cadmium (cd) is a heavy metal that has widespread use. it enters the food chain in different ways, including soil and water. cadmium can cause dysfunction of different body organs. zinc (zn) and magnesium (mg) supplementation can have protective effects against cadmium toxicity due to their antagonistic and antioxidants properties. this study examines the influence of supplemental z...

background: preeclampsia is a disorder of pregnancy without any specific reasons that characterized by high blood pressure and large amounts of protein in the urine. this disorder is caused by multiple factors and finding any factor related to this disorder can help on time prevention of this disease. objective: in this study, serum levels of calcium (ca), magnesium (mg) and zinc (zn) were eval...

background: in the present study, blood serum level of metals were determined in malarial pa­tients and compared with those in the normal subjects without complication using atomic absorp­tion spectrometer. methods: for the determination of these metals twelve intravenous blood samples each from re­ferred malarial patients and a group of normal subjects were collected and immediately centri­fug...

To investigate the impact of calcium, magnesium, zinc, and copper in blood and seminal plasma on semen parameters, 107 fertile and 103 subfertile males provided a standardized blood and semen specimen. Total calcium and magnesium concentrations were determined with colorimetric end point assay procedures. Zinc and copper were determined by flame atomic absorption spectrophotometer (AAS). Semen ...

The clinical efficacy of current antidepressant therapies is unsatisfactory; antidepressants induce a variety of unwanted effects, and, moreover, their therapeutic mechanism is not clearly understood. Thus, a search for better and safer agents is continuously in progress. Recently, studies have demonstrated that zinc and magnesium possess antidepressant properties. Zinc and magnesium exhibit an...
