Background Low birth weight is one of the most important health indicators in evaluating pregnancy care worldwide. We aimed to evaluate the effect of cell phones used in pregnancy on fetal growth and preterm labor. Materials and Methods The search process included screening the rel...
Background: Regarding to the considerable application of microwave in everyday life, their effects on biological tissues are still controversial.This study determines the effect of microwave on morphometric changes in rabbit prostate. Materials and Methods: 18 New Zealand male rabbits were divided into three groups (control, 3 w and 6 w),the animals in the control group were not exposed to micr...
Purpose: According to the problems of visually impaired people in the library, this research aims to introduce a model with respect to existing methods, using RFID technology and cell phone to resolve the problem of searching books without the librarian guidance and investigates the possibility of using this technology in libraries that have open stack. According to the current design, a model ...
In this report, we describe the design, construction, and operation of a cell-phone-based Raman emission spectral detector, which when coupled to diffraction grating cell-phone camera system provides means for detection, recording, identification chemicals, drugs, biological molecules, in situ by their fluorescence spectra. The newly constructed spectrometer was used record spectra from various...

Abstract Background and Objectives: Incidents related to electromagnetic interference with medical devices have been reported over the past decades. It has also been indicated that the microwave radiation emitted from mobile phones interferes with the operation of medical devices therefore, this study aimed at testing the interference by GSM mobile phones with cell counters. Material and Method...
mobile phone use and wireless communication technology have grown explosively over the past decades. this rapid growth has caused widespread global concern about the potential detrimental effects of this technology on human health. stem cells generate specialized cell types of the tissue in which they reside through normal differentiation pathways. considering the undeniable importance of stem ...
Introduction: Radiation from cell phones has been associated with an increased risk of cancer. The literature has reported evidence of certain biological effects resulting from exposure to various wavelengths, doses, and intensities of radiofrequency radiation. The present study aimed to evaluate the possible adverse effects of radiation from a GSM mobile phone operating at 900 MHz on human mel...
