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...

background: induction of cellular response after exposure to electromagnetic fields is limited to coherent fields. an incoherent noise field is supposed to suppress the bioeffects of regular rf electromagnetic fields. the purpose of this study was to investigate the effect of gsm mobile phone-induced radiofrequency (rf) on the induction of oxidative stress in sp2/0 cell line. materials and meth...

Introduction: Today ionizing radiation (IR) plays an important role in medicine, both in diagnostic and therapeutic field. Doctors, medical staff and patients are all in danger of side effects of IR so there is a need to protect them against deleterious effects of ionizing radiation.  Thymus vulgaris has biological activities like antioxidant and antibacterial activity. Aim of...

the aim of this study was to investigate the radioprotective effect of thymol as a natural product against salivary glands dysfunction induced by ionizing radiation in rats. the rats were treated with thymol at dose of 50 mg/kg before exposure to radiation at dose 15gy. salivary gland function was evaluated with radioisotope scintigraphy and then salivary gland to background counts ratio was ca...

objective: on a global scale, stratospheric ozone depletion has caused an increase in uv-b radiation reaching the earth's surface. ultraviolet radiation has long been suspected to be harmful to aquatic organisms. materials and methods: in order to study ionocyte localization (by na+/k+-atpase immunolocalization) and the effects of uv radiation on the ionocytes of skin and gills, the alevins of ...

Background: Drug resistance is widely believed to be an increasingly serious threat to global public health. We have previously reported that short term exposure of microorganisms to diagnostic ultrasound waves could significantly alter their sensitivity to antibiotics. In our previous studies, Klebsiella pneumoniae showed major differences in the sensitivity to antibiotics in exposed and non-e...

Background/Purpose Recent advances in devices involving cardiac catheterization, especially interventional procedures, has lead to increase in examination time and consequent increase in fluoroscopy time and number of filming exposures. Increase in radiation exposure to the patients and the medical personnel has been closed up as a serious agenda. In this study, we focused on the factors that l...

Background: This study aimed to investigate dose area product (DAP), effective dose, and radiation risk in newborn infants hospitalized in neonatal intensive care units in Isfahan and Kashan. Materials and Methods: During a period of six months, DAP for chest X-ray examinations for newborn infants hospitalized in NICUs of five special hospitals including Beheshti (in Kashan), Al-Zahra, Imam Hos...
