Annotated bibliography #3

  1. 1. Seyed M, Gholam R, Mahmood K, Hadi A, Naghmeh S, Ahmad S, ShahrokhS, Faizan A and Ali M. 2009. Effects of mobile phone radiofrequency on thestructure and function of the normal human hemoglobin. International Journal ofBiological Macromolecules 44(3):278-285. Hemoglobin is a protein whose physiological function is to transportoxygen from the lungs to the tissues. Seyed at el. investigated theeffects of mobile phone radiofrequency (910 MHz and 940 MHz) on thestructure and function of hemoglobin (HbA). Oxygen affinity was measuredby using sodium dithionite with Ultraviolet–visible spectrophotometer.Structural changes were studied by circular dichroism (characterizesprotein structure) and fluorescence spectroscopy. It was found that mobilephone electromagnetic fields (EMFs) altered oxygen affinity and thetertiary structure of HbA. It was found that HbA binded less oxygen in thelungs and released more oxygen than normal to the tissues. This findingsuggests that exposure to electromagnetic fields could affect human’snormal respiration. The decrease of oxygen affinity of HbA correspondedto the EMFs intensity and time of exposure.
