The widespread use of cellular telephones has generated concern about possible adverse health effects, particularly brain tumors. In this population-based case-control study carried out in three regions of Germany, all incident cases of glioma and meningioma among patients aged 30-69 years were ascertained during 2000-2003. Controls matched on age, gender, and region were randomly drawn from po...

Supporting interactive, multiplayer games on mobile phones over cellular networks is a difficult problem. It is particularly relevant now with the explosion of mostly single-player or turn-based games on mobile phones. The challenges stem from the highly variable performance of cellular networks and the need for scalability (not burdening the cellular infrastructure, nor any server resources th...

Cellular Communication has become an important part of our daily life. Besides using cell phones for voice communication, we are now able to access the Internet, conduct monetary transactions, send text messages etc. using our cell phones, and new services continue to be added. Therefore, it is important to provide users with a secure channel for communication. This survey paper will give a bri...

RE: " CELLULAR TELEPHONE USE AND RISK OF ACOUSTIC NEUROMA " Christensen et al. (1) recently presented results on the use of cellular telephones and the risk for acoustic neuroma. However, in our opinion, several issues need to be clarified in the paper. Our main concern is that the study did not take into account exposures from cordless phones, and associations specific for ever use of analog o...

BACKGROUND This study evaluates cellular phones for potential risk of nosocomial infection amongst dental operators and auxiliary staff in a dental school. MATERIALS AND METHODS Each participant's mobile phone was first cleaned with 70% isopropyl alcohol swab. Following the cleansing protocol, the partakers were asked to make a short phone call. The mobile phones were then washed aseptically ...

Mash-ups of web content are a quickly growing in popularity due to an increasing amount of public APIs for web services. Similarly, web-enabled cellular phones are becoming increasingly pervasive. We present Lash-Ups, a toolkit that enables programmers to create mash-up-like locationaware web services for phones. This toolkit solves two fundamental problems. First, it provides a simple, standar...

Background In addition to their widespread applications in various fields, cellular phones have some inappropriate social consequences, including psychosocial addiction, degradation of values, reduced social interactions, early maturity and endangering the psychological...

The environment is exposed to electromagnetic radiations as a result of widespread use of wireless communication. This yields a massive increase in electromagnetic pollution. There is a concern of possible adverse effects of cellular phone radiation as a result of the enormous increase in the use of these phones throughout the world. Some studies have been conducted on genetic and biological ef...

Disturbances in hospital devices caused by cellular telephone signals were investigated. The interference sources were GSM900, GSM1800, and TETRA380 phones. The number of medical appliances tested was 23. Most measurements were taken in a semi-anechoic laboratory. To simulate the worst situation, the phones were adjusted to emit at their maximum power levels. No interference was observed if the...

In this number of Clinics we highlight an intriguing study by Narayanan et al., triggered by the tremendous expansion of the use of cellular phones. They exposed Wistar rats to frequent bursts of the vibratory stimulation (no ring tone) produced by cellular phones and found that such stimulus induces a deficit of spatial memory performance using the Morris water maze test. Both groups did exhib...
