Neuroprotective and antioxidant effects of pitaya fruit on Cu-induced stress in adult zebrafish.

The harmful effects of heavy metals on organisms have not been fully described. At present, there is a close relationship between neurodegenerative diseases and copper toxicity. In addition, the copper effect on the central nervous system is followed by high levels of free radicals in different body tissues.

Pitaya fruit extract ameliorates the healthspan on copper-induced toxicity of Caenorhabditis elegans.

Copper (Cu) is an essential metal and it is important for metabolism. However, in high concentrations, it becomes toxic. Metal-induced toxicity is the cause of many neurodegenerative diseases.
