Electromagnetic radiation (EMR) or radiofrequency fields of cellular mobile phones may affect biological systems by increasing free radicals, which appear mainly to enhance lipid peroxidation, and by changing the antioxidant defense systems of human tissues, thus leading to oxidative stress. Mobile phones are used in…

Zinc oxide and gold nanoparticles (ZnONPs and AuNPs) are biomimetically synthesized using Echinacea angustifolia flower extract and their structure and biological activities are reported. In this process, the dried flowers extracts reduced the zinc metal from the precursor Zinc nitrate hexahydrate [Zn(NO 3 ) 2 .4H 2 O…

While initially the oral cavity was considered to be mainly a source of various bacteria, their toxins and antigens, recent studies showed that it may also be a location of oxidative stress and periodontal inflammation. Accordingly, this paper focuses on the involvement of melatonin in oxidative stress diseases of ora…

Modern age exposes humans to an increasing level of electromagnetic activity in their environment due to overhead power lines and transformers around residential areas. Studies have shown that treatment with antioxidants can suppress the oxidative damage induced by electromagnetic fields in various frequencies of the…

BACKGROUND: Melatonin has been suggested to have antiproliferative effects on cancer cells. These effects can be attributed to immunomodulation, growth factor inhibition, induction of apoptosis and prooxidant properties. Melatonin is considered as a safe drug with minimal adverse effects. OBJECTIVES: We planned to inv…
