Simulation of strand breaks induced in DNA molecule by radiation of proton and Secondary particles using Geant4 code
Radiotherapy using various beams is one of the methods for treating cancer, Hadrons used to treat cancers that are near critical organs. The most important part of the cell that is damage by ionizing radiation is DNA. In this study, damages induced in the genetic material of living cells (DNA) defined by the atomic model from the protein data bank (PDB) have been studied by radiati...
متن کاملInvestigation of the direct DNA damages irradiated by protons of different energies using geant4-DNA toolkit
Background: The total yields of direct Single-Strand Breaks (SSBs) and Double-Strand Breaks (DSBs) in proton energies varying from 0.1 to 40 MeV were calculated. While other studies in this field have not used protons with energy less than 0.5 MeV, our results show interesting and complicated behavior of these protons. Materials and Methods: The simulation has been done using the Geant4-DNA too...
متن کامل‘A mover and a shaker’: 53BP1 allows DNA doublestrand breaks a chance to dance and unite
The DNA damage response mediator protein, p53-binding protein 1 (53BP1), is dispensable for the repair of most DNA doublestrand breaks (DSBs) induced by ionising radiation. However, two recent studies have shown that 53BP1 is required for rejoining of distant DSB ends and that it promotes the movement of uncapped telomeres. These results are discussed in the light of recent findings, and a mode...
متن کاملMicrodosimetry study of a multicellular model with mono-energetic electrons using Geant4-DNA simulation toolkit
Introduction: The goal of any type of radiation therapy in the treatment of tumors, in addition to destroying cancer cells, is to minimizing radiation to nearby healthy cells and thus reducing side damages. For this purpose, targeted radiation therapy (TRT) is more effective in treating of single cells or small cluster of cells. The main factor in the success of this method is...
متن کاملQuantification and Optimization of Candida albicans DNA in Blood Samples Using Real- Time PCR
Background: Candida albicans (C. albicans) is a major cause of candidaemia in people with impaired immunity. Blood culture is a “gold standard” for candidaemia detection but is time-consuming and relatively insensitive. We established a real-time PCR assay for C. albicans detection in blood by LightCycler PCR and melting curve analysis. Methods: Five milliliter blood samples from...
