Due to a lack of financial resources, we unfortunately have to suspend the import of any new radio frequency and mobile phone-related articles as of now (November 27, 2017). We apologize for this inconvenience and will keep you informed.

Because we received a large number of inquiries, we set up a bank account to accept donations. With their aid, we hope to resume, at least partly, the import of newly published articles to the RF archive of the EMF-Portal. Any contribution is greatly appreciated. Thank you for your kind support!

Endocrinology. Hormone produced by the pineal gland and released mainly at night in the absence of light on the retina. Changes of melatonin concentration regulate the circadian rhythm in humans and animals. Levels of melatonin decline with age. Melatonin is a potent endogenous free radical scavenger. It also stimulates the gene expression and activity of several important endogenous antioxidant enzymes, including superoxide dismutase, glutathione peroxidase and catalase.
