Diffusing alpha-emitters radiation therapy (Alpha-DaRT) is a unique radiotherapy that uses seeds emitting alpha particles placed in solid tumors to kill cancer cells surrounding the seeds. Although the DNA damage response is an important cellular response that determines cell death after radiation; however, how DNA damage response occurs during Alpha-DaRT treatment has not yet been explored. In this study, we measured the spatiotemporal characteristics of the DNA damage response, including the number of DNA double-strand breaks and G2 arrest, during Alpha-DaRT treatment by cell experiments using HeLa cells expressing the Fucci cell cycle visualization system. As a result, we found a strong correlation between the number of alpha particles detected by solid-state track detector CR-39 and -H2AX staining, a marker for detecting DNA damage, and that the area of G2-arrested cells spread over a wider area up to 24 hours. In addition, time-lapse observations revealed that cell cycle dynamics change depending on the distance from the seed. The experimental model in this study revealed for the first time the spatiotemporal information of the DNA damage response around the seed during Alpha-DaRT treatment.

The Partner Agencies of the International Space Station (ISS) present an intracomparison of the ionizing radiation absorbed dose and risk quantities used to characterize example mission lunar space. The results and the work itself provide insights to the level of agreement with which space agencies can perform organ dosimetry and calculate effective dose. This work was performed in collaboration with the advisory and guidance efforts of the International Commission on Radiological Protection (ICRP) Task Group 115 and will be presented in an ICRP Report

Dryland ecosystems experience seasonal cycles of severe drought and moderate precipitation. Desert plants typically have patchy distributions, and many may develop symbiotic relationships with root endophytic microbes to survive under the repeated wet and extremely dry conditions. Although community coalescence has been found in many systems, the colonization by functional microbes and its relationship to seasonal transitions in arid regions are not well understood. Here we examined root endophytic microbial taxa, and their traits in relation to their root colonization, during the dry and wet seasons in a hot desert of the southwestern United States. We used high-throughput DNA sequencing of 16S rRNA and ITS gene profiling of five desert shrubs, and analyzed the seasonal change in endophytic microbial lineages. In summer, Actinobacteria increased, although this was not genus-specific. For fungi, Glomeraceae selectively increased in summer. In winter, Gram-negative bacterial genera, including those capable of nitrogen fixation and plant growth promotion, increased. Neutral model analysis revealed a strong stochastic influence on endophytic bacteria but a weak effect for fungi, especially in summer. The taxa with higher frequency than that predicted by the neutral model shared environmental adaptability and symbiotic traits, whereas the frequency of pathogenic fungi was at or under the predicted value. These results suggest that community assembly of bacteria and fungi is regulated differently. The bacterial community was affected by stochastic and deterministic processes via the bacterial response to drought (response trait) and beneficial effect on plants (effect trait). For fungi, mycorrhizal fungi were selected by plants in summer. The regulation of beneficial microbes by plants in both dry and wet seasons suggests the presence of plant-soil positive feedback in this natural desert ecosystem.
