background : the association of the mobile phone use and risk of brain tumor remains controversial among radiationepidemiologists. methods : we hypothesized if an association between brain tumor and mobile phone use exists, this association will be manifested as a cohort effect (as a proxy of association between mobile phone use and brain tumor) in the incidence rates of brain tumor during the ...

Background: There has been a growing claim that cell phone usage may have a detrimental effect on sperm chromatin. Infertile men possess anomalies in the composition of their sperm nuclei, displaying higher levels of loosely packaged chromatin and damaged DNA. In this study we examined the relationship of cell phone radiation and the protection effect of alpha_tocopherol on human sperm DNA. Mat...

objectives: most studies have performed to identify the affective variables in using mobile phone by drivers based on interview and questionnaire. in this study call answering rate while driving was investigated in a sample of male postgraduate students of a university in tehran by a driving simulator. methods: six driving scenario designed differing in risk of driving. answer rate to mobile ph...

background: whether exposure to common electromagnetic fields affects human health adversely has been a controversial issue. the main goal of this study was to assess the role of 900 mhz microwave radiations with different specific absorption rates (sars), emitted from some widely used cell phones, on the induction of adaptive response in male balb/c mice after receiving a lethal dose of gamma ...

Background: The risk of cell phone addiction is a social and psychological problem which has been proposed by ‎psychologists, psychiatrists, and educational supervisors. The present study aimed to investigate the ‎behavior of mobile phone addicts and mental health of university students of Shahrekord, Iran‎. Methods: This study was an applied research survey for the purposes of this study. The ...

Background:  Widespread and growing sources of electromagnetic radiation raised concerns attributed to the potential adverse health risk of radiofrequency fields. Given the functional importance of the hippocampus, this study aimed to investigate the effects of electromagnetic waves radiated by mobile jammer on hippocampal expression of p21 and p53 genes as regulators of cellular apoptosis...

background: the use of mobile phone by children is increasing drastically. children are likely to accumulate many years of exposure during their lives. furthermore, as nervous systems in children are developing, children may be at a greater risk compared to adults. in this light, some scientists have suggested that the use of mobile phones should be restricted in high-risk groups such as childr...
