The increased use of mobile phones worldwide has focused interest on the biological effects and possible health outcomes of exposure to radiofrequency fields from mobile phones, and their base stations. Various reports suggest that mobile phone use can cause health problems like fatigue, headache, dizziness, tension, and sleep disturbances; however, only limited research data is available in me...

Mobile phones are becoming increasingly important for forensic investigations. Users generate a lot of data by playing mobile games. We tried to replicate the 2016 research that forensically extracted usage and location from Pokémon GO app's storage. In an experiment, actions taken with app were manually logged compared obtained logical physical imaging two cell phones. found while there is les...

Background and purpose: Incidence of breast cancer is increasing day by day. Scientists are interested in the effects of inhibition of breast cancer cell on treatment of this cancer. The aim of this study was to determine IC50 of doxorubicin in 24 hours on cell lines MCF-7 and MDA-MB-231 and the expression of heat shock protein HSP90α as a factor in the cell before and after 24 hours expo...

Use of optical imaging for medical and scientific applications requires accurate quantification of features such as object size, color, and brightness. High pixel density cameras available on modern mobile phones have made photography simple and convenient for consumer applications; however, the camera hardware and software that enables this simplicity can present a barrier to accurate quantifi...

BACKGROUND As the use of mobile phones is increasing, public concern about the harmful effects of radiation emitted by these devices is also growing. In addition, protection questions and biological effects are among growing concerns which have remained largely unanswered. Stem cells are useful models to assess the effects of radiofrequency electromagnetic fields (RF-EMF) on other cell lines. S...

Introduction: Electrochemotherapy (ECT) is a cancer treatment modality to permeabilize cell membrane facilitating the non-permeant molecules to gain access to the cytosol of cells. Nevertheless, environmental electromagnetic fields (EMFs) may disturb the efficiency of ECT. The present study aimed to investigate the effect of EMFs 900 MHz pulse-modulated by 217 Hz extremely low-frequency fields ...

Background: Pre-exposure to radiofrequency radiations of mobile phones would significantly increase the survival rate of exposed animals compared to those exposed to a lethal dose of gamma radiation alone. Stimulation of the immune system is believed to be a key mechanism for the induction of this phenomenon, the so-called “adaptive response.” The immune system protects organisms against in...

As public concern mounts over exposures to ionizing radiation stemming from environmental releases of radionuclides following nuclear accidents, there is a growing need to develop reliable techniques that reconstruct exposures and doses to individuals. Especially in situations where conventional dosimeters were not in place at the time of facing to radiation exposure. In order to provide guidan...
