As an essential trace element, copper can be toxic in mammalian cells when present in excess. Metallothioneins (MTs) are small, cysteine-rich proteins that avidly bind copper and thus play an important role in detoxification. Yeast CUP1 is a member of the MT gene family. The aim of this study was to determine whether yeast CUP1 could bind copper effectively and protect cells against copper stre...

The reuse of mineral wastes is one of the most suitable solid wastes solutions. Throughout the world, the large of the granular aggregates used in constructions exploit natural mountain resources and rivers. Using mineral waste as a part of concrete, it can be helped to create a green environment and also contribute to sustainable development. Since the copper production process in the Sarchesh...

The Moldavian dragonhead (Dracocephalum moldavica L., Lamiaceae) is an annual medicinal plant with beneficial nutritional sources that plays important roles in human and animal feed. Nanoparticles and cold atmospheric plasma increase biochemical compounds in plants. In this study, the effects of copper nanoparticles and cold atmospheric plasma on biochemical indices of the medicinal plant Draco...

background: industrial copper ingest is a common form of poisoning in animals. zinc has an important role in the physiology of spermatozoa, in sperm production and viability. objective: this study was set to investigate whether the adverse effects of long term copper consumption on quality of rat spermatozoa could be prevented by zinc therapy. materials and methods: forty eight mature (6-8 week...

The present work is concerned to remove Cu using the biosorption potential of fungal biomass Aspergillus oryzae. The dry fungal biomass was used to optimize various parameters such as contact time, initial metal ion concentration, pH, biomass loading etc. A maximum of 91% Copper removal was observed in 5 mg/L initial Copper metal ion concentration using dry Aspergillus oryzae biomass. The perce...
