The most deleterious radiation-induced damages are double strand breaks (DSBs) and among early signals of cellular response to DSB there is phosphorylation of protein histone H2AX [ 32].
Finally, there are probable deleterious effects of radiation in producing congenital malformations, certain leukemias, and possibly some genetic disorders (see radiation: Biologic effects of ionizing radiation).
A deleterious effect of radiation is the production of reactive oxygen species, which result in damage to biomolecules (e.g., lipid, protein, amino acids, and DNA).
Distraction osteogenesis (DO) can avoid many of the pathologies of current reconstructive strategies; however, due to the deleterious effects of radiation on bone vascularity, DO is generally ineffective.
The present study explores the potent of gamma-aminobutyric acid (GABA) treatment for the deleterious effects of radiation where GABA is considered to be the major inhibitory neurotransmitter in the central nervous system (Hori et al., 2013).
Taking advantage of this, an "exposure filtering" method was recently proposed (Grant and Grigorieff 2015), which optimizes the SNR of every frame collected, thereby minimizing the deleterious effects of radiation damage.
While significant advances in treatment have been made, with the 5-year survival rate for medulloblastoma at 70 80%, treating patients under 3 years of age still poses a problem due to the deleterious effects of radiation on the developing brain, and the median survival for patients with glioblastoma is only 15 months.
