Extremely low frequency electromagnetic fields affect proliferation and mitochondrial activity of human cancer cell lines.

Purpose: To date, the effects of electromagnetic fields on cell metabolism have been overlooked. The objective of the present study was to investigate the influence of extremely low frequency electromagnetic fields (ELF-EMF) over mitochondrial metabolism and the consequent impact on cancer cell growth.

Materials And Methods: The effects of ELF-EMF on cancer growth were investigated in several human cancer cell lines by crystal violet assay.

Constructal thermodynamics combined with infrared experiments to evaluate temperature differences in cells.

The aim of this work was to evaluate differences in energy flows between normal and immortalized cells when these distinct biological systems are exposed to environmental stimulation. These differences were considered using a constructal thermodynamic approach, and were subsequently verified experimentally. The application of constructal law to cell analysis led to the conclusion that temperature differences between cells with distinct behaviour can be amplified by interaction between cells and external fields.
