Reactive oxygen species (ROS) have been indicated in the development of diseases such as cancer, cardiovascular diseases, degenerative diseases and ageing. An increasing body of evidence indicates an association between increased and persistent oxidative stress and the development of radiation damage in tissues such as skin, central nervous system and kidney. On the basis of the new hypothesis ...

background: the rationale was to develop an ablation approach to destroy regions of tumor resistant to radiation and thus reduce the time required for whole tumor ablation, while improving overall tumor control after radiotherapy. materials and methods: the system is composed of a micro positron emission tomography (mpet), 7t magnetic resonance imaging (mri), and a customized mri-compatible foc...

background: ultraviolet (uv) radiation is divided into three regions: uva, uvb, and uvc. both the quality and quantity of solar uv radiation vary with various factors including the elevation of the sun above the horizon, as well as absorption and scattering of uv photons by molecules in the atmosphere, notably ozone and clouds. it is clear that whereas a moderate amount of uv exposure is benefi...

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...

Background: Extensive research has been focused on radiation induced brain injury. Animal and human studies have shown that flavonoids have remarkable toxicological profiles. This study aims to investigate the neuroprotective effects of hesperidin in an experimental radiation induced brain injury. Materials and Methods: 32 adult male Wistar-Albino rats were randomly divided into 4 groups (contr...

Introduction: Radiation has a negative biologic effect, which depends on the duration of exposure and dose. This study aimed to assess knowledge of the principles of radiation protection among medical staff in educational hospitals in Bandar Abbas University of Medical Sciences. Materials and Methods: This descriptive cross-sectional study was carried out on 105 health workers who were exposed ...

Background: The publicchr('39')s understanding of radiation and protection of radiation harm is not high. Therefore, it is meaningful to know the radiation safety literacy level in terms of health care. This study developed a measurement tool that can help to identify the actual condition of radiation safety literacy and conducted the statistical assessment of the developed tool. Materials and ...
