With respect to the dramatic increasing use of electronically communicators and wireless modems, concerns have been raised about the possible effects of emitted electromagnetic radiation on human brain. In this paper, the effects of high-frequency wireless modem waves on the brain signal are investigated. To this end, the Electroencephalograph (EEG) recording of 15 volunteers is examined in fou...

Introduction: Despite the extensive use of ionizing radiation in diagnosis and therapeutic procedures, development of radio-protector agents is important in modulating normal tissue damages. Hesperidin(HES) is a Flavanone glycoside, belonging to the Flavonoid family in human diet abundantly and noted for its many beneficial effects. The aim of present study was investigated to ...

Introduction The exposure of human beings to ionizing radiation from natural sources is a continuing and inescapable feature of life on earth. For most individuals, this exposure exceeds that from all man-made sources combined. Materials and Methods In this study, the annual effective dose in high level environmental background radiation areas (HLEBRAs) of northern city of Ramsar in Iran was de...

background: ionizing radiation induces the production of reactive oxygen species (ros), which play an important causative role in cell death. the aim of this study was to investigate the protective effects of sulfated derivatives of neutral polysaccharides extracted from auricularia auricular (snaap). materials and methods: whole blood samples from healthy donors treated with snaap at different...

Although there are substantial experimental, epidemiological and clinical evidences that high doses of ionizing radiation cause cancer and other detrimental biological effects, the health effects of human exposure to chronic low dose radiation exposures are still poorly known. People in some areas around the world live in dwellings with radiation and radon levels as much as more than 2...

Introduction: Radiation effects observed in cells that are not irradiated are known as non-targeted effects.  Radiation induced bystander effect (RIBE) as a kind of non-targeted effect has been introduced in recent  years.  RIBE  occurs  in  unexposed  cells  which  are  related  to  adjacent  or  distant  irradiated  cells.  RIBE  contradict with "target theory" which necessitates radiation tr...

many cellular damages either in normal or cancerous tissues are the outcome of molecular events affected by ionizing radiation. t‑cells are the most important among immune system agents and are used for biological radiation dose measurement in recommended standard methods. the herbs with immune modulating properties may be useful to reduce the risk of the damages and subsequently the diseases. ...

Introduction: The fast-growing telecommunication and wireless technologies has led to more dependence to these communication devices and higher levels of exposure to electromagnetic radiations propagated by cellular devices and their service towers. To disable signaling in places where silence is valued or where information quarantine measures are required, mobile phone jammers emit radiofreque...
