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 differen...

Background: Due to abscopal effect, cell damage may occur outside of the radiation field and the quantification of this effect is one of the most challenging debates in radiation therapy. The aim of this study was to estimate the abscopal effect induced in non-irradiated tumors quantitatively by means of biological effective dose (BED). Materials and Methods: Breast tumors using 4T1 and MC4-L2 ...

In this paper, we use the observations of Sunyaev-Zel’dovich effect and Xray surface brightness to reconstruct the radial profiles of gas temperature and density under the assumption of spherically symmetric distribution of gas. The reconstruction method, firstly raised by Silk & White (1978), is directly dependent on the experimental measurements of Sunyaev-Zel’dovich effect and X-ray surface ...

The radiation-induced bystander effect is the phenomenon which non-irradiated cells exhibit effects along with their different levels as a result of signals received from nearby irradiated cells. Responses of non-irradiated cells may include changes in process of translation, gene expression, cell proliferation, apoptosis and cells death. These changes are confirmed by results of some In-Vivo s...
