Summary: Cu2+ and Co2+ metals can increase DNA damage in the presence of hydrogen peroxide. Cu2+ is more efficient than Co2+ at inducing both DNA single-strand and double-strand breaks. The effect of radiation and chemical treatments on Cu2+ and Co2+ varies, with positive correlation for single-strand break formation and negative correlation for double-strand break formation.

Summary: High-energy heavy ions can cause DNA damage, leading to cellular responses such as cell cycle arrest, cell death, and cellular senescence. Prolonged exposure to high-energy ions in space radiation increases the risk of gastrointestinal (GI) carcinogenesis. Alterations in DNA damage response (DDR) can result in gene mutations and pro-inflammatory, pro-oncogenic signaling, accelerating adenoma-to-carcinoma progression during radiation-induced GI cancer development.

Summary: DNA damage and repair studies are essential in radiation biology and play a crucial role in informing radiation therapy. The level and type of DNA damage are influenced by radiation dose and quality (LET), ultimately determining cell fate. Different modalities of radiation therapy have varying effects on DNA damage and repair mechanisms, impacting biological responses.

Summary: DNA double-strand breaks (DSBs) are the main cause of cell death in carbon-ion radiation therapy (CIRT). Nuclear interactions between primary carbon ions and targets lead to nuclear fragmentation and the production of secondary particles. These particles travel to the tail region, causing unwanted biological effects. The density of DSBs within high-LET track structures plays a crucial role in inducing cell death.

Summary: Double strand breaks (DSBs) are severe DNA lesions that can lead to cancer if not repaired. This study focuses on the use of gamma H2AX and 53BP1 foci as markers to study DSBs and their repair kinetics. By detecting the co-localization of these markers near DSBs, a dual immunofluorescence protocol is established to quantify DSBs induced by the radiomimetic agent bleomycin in human lymphocytes. The variation in the number of gamma H2AX and 53BP1 foci over time is also examined to understand the repair kinetics of bleomycin-induced DSBs.

Summary: In cellular experiments, a practical modelling has been developed to simulate the occurrences of double-strand breaks (DSBs) and the formations of gamma-H2AX foci in response to individual DSB formations, in cell nucleus due to exposure to alpha particles. This computational modelling can better implement the conventional gamma-H2AX assay.

Summary: In this study, the induction and repair of radiation-induced 53BP1 foci were examined in human umbilical vein endothelial cells irradiated with protons and alpha-particles of varying energies. The analysis of data revealed that the disappearance of foci follows first order kinetics. Interestingly, the absolute number of persistent foci increased with energy loss but their fraction remained constant. Protons were found to produce more persistent foci compared to even higher energy loss alpha-particles, suggesting that protons may be more effective in causing severe DNA damage.

Summary: This study proposes a possible approach to evaluate tumor-targeting Auger-labeled conjugates by assessing the impact of a radioprotector. The results of radioprotection experiments with 25 kVp X-rays show that the extent of radioprotection was comparable for all radiation conditions, although the relative biological effectiveness (RBE) was higher for soft X-rays.

Summary: Coal mining activities release compounds that can cause oxidative damage to DNA. We compared blood samples from 150 individuals exposed to coal mining residues and 120 non-exposed individuals, finding higher concentrations of certain elements and hypokalemia in the exposed group. The enzyme-modified comet assay suggests that coal mining residues cause oxidative DNA damage, especially to purines. Understanding the effects of these inorganic elements on DNA damage and oxidative stress pathways is crucial for understanding the impact of coal mining residues on human health.

Summary: The nEXO neutrinoless double beta decay experiment aims to detect the decay in Xe-136 using a time projection chamber and 5000 kg of isotopically enriched liquid xenon. The experiment has made significant improvements in detector design, simulation accuracy, and data analysis methods, leading to a sensitivity prediction that exceeds the half-life of 10^28 years. It is expected that in 10 years of data taking, the nEXO experiment will reach a sensitivity of 1.35 x 10^28 years, covering a wide range of parameter space associated with neutrino mass ordering.

Summary: Monte Carlo simulations are commonly used in nuclear physics to model experimental systems. This study presents a Bayesian approach to fitting experimental data from a Be-12(d,p) reaction measurement, using simulations made with GEANT4. The Q-values from the C-12(d,p) reaction to well-known states in C-13 are compared with simulations using BayesOpt. The results show successful extraction of excitation energies of the lowest three excited states in C-13, providing a way to obtain information on Be-13.

Summary: In this study, the beta-delayed neutron-emission probabilities of 28 exotic neutron-rich isotopes were measured for the first time using advanced detectors. The results significantly expanded the existing database and improved the accuracy of previously measured values. The new data not only contribute to the understanding of theoretical predictions, but also provide insights into the formation mechanisms of rare-earth peaks and reduce abundance uncertainty.

Summary: Liquid xenon time projection chambers are promising detectors for neutrinoless double beta decay, and the nEXO collaboration has designed a tonne-scale chamber with a projected half-life sensitivity of 1.35 x 10^28 yr. This paper reports on the characterization of vacuum ultra-violet sensitive SiPMs designed for nEXO, as well as measurements on new test samples of previously characterized MPPCs. The results are used to provide updated estimates of the achievable energy resolution for the nEXO design.

Summary: Reactions on proton-rich nuclides play a crucial role in nucleosynthesis in core collapse supernovae and x-ray bursts. However, the Ni-Cu cycle may pose a challenge for the production of heavier elements during the Cu-59(p, alpha) Ni-56 reaction. New research suggests that the vp process could operate at higher temperatures, making it a viable pathway for synthesizing heavier elements.
