Background : The rapid development of communication and mobile use has generated discussions about changing people's life and their dependence on cell phones. Dependence to mobile phone creates a sense of loneliness and unsuitable social support. This study aimed to determine the relationship between cell phone use and loneliness and social support scores in Tehran University of Medical Scien...
Wireless technologies are ubiquitous today and the mobile phones are one of the prodigious output of this technology. Although the familiarization and dependency of mobile phones is growing at an alarming pace, the biological effects due to the exposure of radiations have become a subject of intense debate. The present evidence on mobile phone radiation exposure is based on scientific research ...
background: astronauts will be exposed to both chronic space radiation and acute high doses of energetic radiation of solar particle events in long-term deep space missions. the application of radioprotectors in space missions has basic limitations such as their very short time window as well as their acute toxicity and considerable side effects. the aim of the present study was to investigate ...
Introduction & Objective: Regarding increasing the rate of cell phones use and its' subsequent dependency in such instrument among young people and also considering the important role of self-regulation and self-control traits on health related issues and the roles of such issues in problematic and addictive behaviors, this study has been designed to evaluate the predictive role of self-regulat...
Background and Aim: Considering the great advances and extensive use of cell phones and its effects on the human communications and interactions, investigation of potential negative effects of cell phones on the users' health is necessary. The aim of this study was to determine the effect of the distance between cell phones and brain tissue on the temperature of the central and gray matters of ...
INTRODUCTION It is impossible to imagine a modern socially-active man who does not use mobile devices and/or computers with Wi-Fi function. The effect of mobile phone radiation on male fertility is the subject of recent interest and investigations. The aim of this study was to investigate the direct in vitro influence of mobile phone radiation on sperm DNA fragmentation and motility parameters ...
A method is described for measuring absorbed electromagnetic energy radiated from cell phone antennae into ex vivo brain tissue. NMR images the 3D thermal dynamics inside ex vivo bovine brain tissue and equivalent gel under exposure to power and irradiation time-varying radio frequency (RF) fields. The absorbed RF energy in brain tissue converts into Joule heat and affects the nuclear magnetic ...
OBJECTIVE: To investigate the effect of cell phone use on various markers of semen quality. DESIGN: Observational study. SETTING: Infertility clinic. PATIENT(S): Three hundred sixty-one men undergoing infertility evaluation were divided into four groups according to their active cell phone use: group A: no use; group B: <2 h/day; group C: 2-4 h/day; and group D: >4 h/day. INTERVENTION(S): None....
Background and Objectives: The use of new technologies, particularly mobile phones, is drastically growing on a daily basis. The usability of mobile phones can be determined for different age groups in order to reach a balanced development plan with respect to this technology. The present study aimed to investigate and compare the usability of touch-screen and button cell phones among Iranian e...
