Summary: In this study, exclusive measurements for eta photoproduction on a proton target are reported, including the differential cross sections and photon beam asymmetries. The results reveal a bump structure at specific energy and angular ranges, which is likely associated with high-spin resonances.

Summary: The study aimed to develop and histologically characterize a swine model of lung cancer for preclinical studies evaluating locoregional therapies. Tumors induced in the lungs of Oncopigs are fast growing poorly differentiated neoplasms associated with a marked inflammatory reaction. This large animal model might be suitable for interventional and surgical therapies of lung cancer.

Summary: This study aims to establish the dose-response relationship of DLPFC stimulation through concurrent TMS/fMRI. The study found qualitative inter-subject variability in the dose-response relationship to TMS over left DLPFC, suggesting that the motor threshold may not be directly transferable to the excitability of the DLPFC. Therefore, concurrent TMS/fMRI may have the potential to improve response rates to TMS applications.

Summary: This study investigates the effects of low-dose exposures of accelerated protons on DNA damage induction, survival, and transformation in human fibroblasts. The results show that DNA double-strand breaks and clustered DNA damages induced by proton irradiation are dependent on dose-rate and linear energy transfer. The cell survival and transformation exhibit a dose-rate effect, which is more significant at SPE-like LDR doses.

Summary: The conventional termination technique for life threatening cardiac arrhythmia has severe side-effects. Using lower energy pulse sequences instead of single high-energy pulses is a promising approach to improve the current treatment. Numerical simulations show that the dose-response function of pulse sequences applied to spiral wave chaos exhibits non-monotonous increasing behavior and frequency dependence, providing a deeper understanding of termination mechanisms.

Summary: This paper identifies six major conceptual scientific errors made by Hermann Muller and explains how these errors led to the development of the linear no-threshold (LNT) dose response, which has been widely used worldwide for cancer risk assessments. The paper highlights the significant influence Muller had in the environmental movement, impacting risk assessment policies that are still in use even decades after his death. It also supports current research showing the limitations of the LNT model for cancer risk assessment.

Summary: The protein expression and subcellular localization of T-type voltage-dependent Ca2+ channels (Cav3) were evaluated in human breast tissue samples. It was found that the nuclear expressions of CaV3.1, CaV3.2, and CaV3.3 decreased in advanced stages of neoplastic transformation, while the cytoplasmic expression of CaV3.1 and CaV3.2 increased. The change in protein expression and subcellular localization of CaV3 corresponded with the neoplastic transformation stages, suggesting a possible involvement of CaV3 in the carcinogenic processes and its potential as a pharmacological target in breast cancer treatment.

Summary: This study reports that a large elastic-like strain of over 4% can be achieved in a tweed textured Fe-Pd single crystal under a compressive stress of 300 MPa. This giant elastic response gives rise to a significant and homogenous elastocaloric effect, which can sustain stable performance during a large number of mechanical cycles.

Summary: The study demonstrates that in healthy humans, ERFE responds to slight increases in Epo levels without Hb mass expansion, and downregulates hepcidin in an apparently iron-independent manner. Notably, ERFE levels are positively correlated with micro-dose Epo administration, suggesting its potential as a new biomarker for doping detection.

Summary: Shielding from space radiation, especially galactic cosmic rays (GCRs), is a significant safety challenge for future human activities in deep space. In this study, the shielding performances of potential materials [aluminum (Al), polyethylene (PE), and carbon fiber reinforced plastic (CFRP)] were investigated using Geant4 Monte Carlo simulation considering two types of biological scale parameters, the International Commission on Radiological Protection (ICRP) quality factor (QF(ICRP)) and the plausible biological effectiveness (RBE gamma acute), for GCRs. It was found that spacecraft made from CFRP had better radiation shielding performance than conventional Al-based spacecraft. The contribution of heavy ions for QFICRP based effective dose equivalent was larger compared to that for RBE gamma acute based effective dose equivalent. It is necessary to establish a standard parameter specified for a mixed radiation environment occupied by protons and heavy ions for practical dose assessment in deep space.

Summary: This study investigates the transport and attenuation of PFOA induced by iron (hydr)oxide dynamic transformation and reveals that groundwater type does not affect the pathway of PFOA attenuation, but it controls the differences in iron (hydr)oxide dynamic transformation. The dynamic transformation of iron (hydr)oxide significantly affects the transport behavior of PFOA.

Summary: The introduction of chloride ions in the iron-based PAA system can enhance the reaction rate and improve the removal capacity for contaminants. The presence of chloride ions induces the generation and conversion of ROSs, leading to effective decontamination. The treatment with iron-based PAA can also alleviate the biological toxicity of pollutants.

Summary: Electrical signals in plants can induce physiological responses, and the role of calcium ions in the respiratory response induced by electrical signals has been investigated. The activation of respiration is likely associated with calcium-mediated activation of alternative NADPH dehydrogenases in mitochondria.
