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...

OBJECTIVES Scientific interest in potential mobile phone impact on human brain and performance has significantly increased in recent years. The present study was designed to evaluate the effects of mobile phone radiation on seizure threshold in mice. MATERIALS AND METHODS BALB/c male mice were randomly divided into three groups: control, acute, and chronic mobile phone radiation for 30, 60, a...

Some concern has arisen about adverse health effects of cell phones, especially the possibility that the low power microwave-frequency signal transmitted by the antennas on handsets might cause brain tumors or accelerate the growth of subclinical tumors. We analyzed data from the Statistical Report: Primary Brain Tumors in the United States, 2000–2004 and 2007 cell phone subscription data from ...

Recent studies have shown that exposing human semen samples to cell phone radiation leads to a significant decline in sperm parameters. In daily living, a cell phone is usually kept in proximity to the groin, such as in a trouser pocket, separated from the testes by multiple layers of tissue. The aim of this study was to calculate the distance between cell phone and semen sample to set up an in...

Despite the widespread use of mobail phones in Iranian students, psychological and behavioral effects of addiction to it and its consequences have not been investigated yet. The aim of this study was to determine the relationship between cell phone dependency with psychological disorders and academic burnout among nursing and midwifery students. In this study, 169 students were chosen through s...

Several studies have demonstrated detrimental effects of cellular phone radiation on in-vitro biological systems. This article introduces a novel in-vitro method for demonstrating conformational changes in human DNA induced by a 5 minute exposure to cellular phone radiation emitted by an actual contemporary cellular phone. Dynamic changes in DNA conformation was determined in real-time by measu...
