Mobile phones are two-way radios that emit electromagnetic radiation in microwave range. As the number of mobile phone users has reached 6 billion, the bioeffects of exposure to mobile phone radiation and mobile phone electromagnetic interference with electronic equipment have received more attention, globally. As self-monitoring of blood glucose can be a beneficial part of diabetes control, ho...

This project is developed with aims to improve home security systems available in current market. This project claims to produce a prototype camera and global system for mobile communication (GSM) interfacing system for home security surveillance. This system uses two sensors, namely ultrasonic and passive infrared receiver (PIR). The ultrasonic sensor is used to detect movement of objects and ...

Background: Self-mutilation is one of the most extreme types of self-harm, which is done deliberately to hurt the body, regardless of suicidal intent. In self-mutilation, the most important targets are the eyes, genital tract, and hands. So far, genital self-mutilation (GSM) has been less frequently reported around the world. According to our study, this is the first case of GSM reported in Ira...

γ-Secretase modulation has been proposed as a potential disease modifying anti-Alzheimer's approach. γ-Secretase modulators (GSMs) cause a product shift from the longer amyloid-beta (Aβ) peptide isoforms to shorter, more soluble, and less amyloidogenic isoforms, without inhibiting APP or Notch proteolytic processing. As such, modulating γ-secretase may avoid some of the adverse effects observed...

The widespread use of wireless cellular networks has made security an ever increasing concern. GSM is the most popular wireless cellular standard, but security is an issue. The most critical weakness in the GSM protocol is the use of one-way entity authentication, i.e., only the mobile station is authenticated by the network. This creates many security problems including vulnerability against m...

Effects of nonthermal radiofrequency radiation (RFR) of the global system of mobile communication (GSM) cellular phones have been as yet mostly studied at the molecular level in the context of cellular stress and proliferation, as well as neurotransmitter production and localization. In this study, a simulation model was designed for the exposure of pregnant rats to pulsed GSM-like RFR (9.4 GHz...
