The degree to which radiation from a loudspeaker is diffuse may be quantified by a spatial correlation function normalised to the on-axis response. This is true for any loudspeaker type, including the distributed-mode loudspeaker (DML). However, because of the variation in material damping and design-related constraints, correlation commonly varies both with frequency and direction. A modified ...

Alternative splicing is a critical event in the posttranscriptional regulation of gene expression. To investigate whether this process influences radiation-induced gene expression we defined the effects of ionizing radiation on the generation of alternative transcripts in total cellular mRNA (the transcriptome) and polysome-bound mRNA (the translatome) of the human glioblastoma stem-like cell l...

introduction this study was conducted to evaluate the radiographers’ awareness of radiation protection principles in the radiology centers of the hospitals of bandar abbas, iran. materials and methods this analytical cross-sectional study was conducted on 50 radiographers of three hospitals affiliated with hormozgan university of medical sciences in 2015. the data were collected using a two-par...

background: although ionizing radiation is very important in diagnostic and treatment of many diseases, the hazards of this radiation are considerable and irrefutable. one of the main stages in radiation protection is knowledge about radiation dose in radiological investigation. the aim of this study was to determine the physicians' knowledge in radiological examinations. materials and methods:...

background: the number of interventional cardiology procedures performed has increased rapidly over the past years. while these procedures help physicians avoid using highly complicated invasive methods, it usually leads to high levels of exposure to ionizing radiation of both patients and cardiologist. the dose received by the cardiologist during interventional cardiology procedures is determi...

conclusions the state of observed radiation protection principles was relatively in the weak level in the studied radiology departments especially in facilities such as ventilation system, radiography entrance, and darkroom situation. more important reason was usage changing of sections as radiology billet from related organizations. results the mean of radiation protection in the studied radio...

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...

Radiation-induced second non-mammary malignancies are infrequent long term complications of the therapy. Angiosarcoma is particularly challenging to diagnose given its rare presentation (less than 1% of all malignancies of the breast) and clinical resemblance to radiation-induced skin changes [1]. Therefore, it is crucial to have a high index of suspicion in these patients. It is commonly seen ...

This article provides a summary of presentations focused on critical education and training issues in radiation oncology, radiobiology and medical physics from a workshop conducted as part of the 60th Annual Meeting of the Radiation Research Society held in Las Vegas, NV (September 21-24, 2014). Also included in this synopsis are pertinent comments and concerns raised by audience members, as we...
