The paper \"MPEXS-DNA, a new GPU based Monte Carlo simulator for track structures and radiation chemistry at the subcellular scale\" has received the 2018-2019 Top Download Award. The paper was written by Shogo Okada, assistant professor at the Computing Research Center, and others, and was published in the journal. The award is given to the papers with the 10% most downloads in the 12 months since its online publication in AAPM (The American Association of Physicists in Medicine) Medical Physics. This indicates that the research has received a great deal of attention. Professor Takashi Sasaki, associate professor Koichi Murakami, and researcher Amako Katsuya are also co-authors on this paper from the Computing Research Center.<\/p>\n\n\n\n
Dr. Okada explains the paper
The Computing Research Center is conducting research related to the elucidation of the mechanism of radiation damage in DNA by Monte Carlo simulations as part of an interdisciplinary research project. When cells are exposed to radiation, free radicals are produced. This reacts with DNA molecules and causes damage (see figure below). If DNA damage can be estimated by simulation, it will be possible to quantitatively evaluate the effects of low-dose radiation exposure on the human body, such as astronauts. It is also expected to lead to research for the advancement of radiotherapy for cancer.<\/p>\n\n\n
