BACKGROUND Use of cellular phones emitting radiofrequency electromagnetic field (RF-EMF) has been increased exponentially and become a part of everyday life. This study aimed to investigate the effects of in vitro RF-EMF exposure emitted from cellular phones on sperm motility index, sperm DNA fragmentation and seminal clusterin (CLU) gene expression. MATERIALS AND METHODS In this prospective ...

OBJECTIVES A widespread use of mobile phones evokes a growing concern for their possible adverse effects on the human central nervous system. This study was aimed at evaluating the effects of EMF generated by mobile phones, at all standard wavelengths: 450, 935 and 1800 MHz used in Poland, on the auditory brainstem-evoked responses (ABR) during and after the exposure. MATERIALS AND METHODS Th...

To investigate the effect of microwave emitted by mobile phones on the rat central nervous system (CNS), in vitro cultured cortical neuronal cells and in vivo rat’s brain were exposed to the electromagnetic waves emitted by a microwave transmitter that mimics the working frequency of mobile phones. Trypan blue staining and terminal deoxynucleotidy transferase-mediated dUTP nick-end labeling (TU...

Background: Widespread of telecommunication systems in recent years, have raised the concerns on the possible danger of cell phone radiations on human body. Thus, the study of the electromagnetic fields on proteins, particularly the membrane nano channel forming proteins is of great importance. These proteins are responsible for keeping certain physic-chemical condition within cells and managin...

Wide concerns have been raised that the use of cell phones could increase brain tumors. This paper systematically reviews the scientific evidence regarding the associations between cell phone use and brain tumors. The authors’ review suggests two conclusions. First, it is still controversial in regard with the significant associations between cell phone use and increased risk of brain tumors. S...

Electromagnetic fields (EMFs) include everything from cosmic rays through visible light to the electric and magnetic fields associated with electricity. While the high frequency fields have sufficient energy to cause cancer, the question of whether there are human health hazards associated with communication radiofrequency (RF) EMFs and those associated with use of electricity remains controver...
