Summary: Exposure to isoprocarb induces developmental toxicity, hindbrain defects, and impaired motor ability in zebrafish embryos. The expressions of genes involved in neurodevelopment signaling pathways are inhibited, and oxidative stress is induced, which may be the molecular basis of isoprocarb-induced neurotoxicity in zebrafish embryos.

Summary: Nano-ZnO exhibits excellent antibacterial properties but can cause hepatotoxicity leading to the development of fatty liver disease in zebrafish. Our study reveals that Nano-ZnO triggers oxidative and endoplasmic reticulum stress, promoting fatty acid synthesis and steatosis. Treatment with carbon dots alleviates the hepatotoxicity of Nano-ZnO.

Summary: The herbicide flumioxazin has been found to induce cardiac defects in vertebrates, possibly due to oxidative stress. This study investigated the underlying mechanisms and found that flumioxazin caused cardiac malformations and abnormal gene expression associated with cardiac development. It also led to increased oxidative stress and apoptosis in the zebrafish heart. The antioxidant astaxanthin reversed these effects and protected against flumioxazin-induced cardiotoxicity.

Summary: The study showed that bifenazate exposure has significant toxicity to aquatic organisms, especially zebrafish. Exposure to bifenazate causes severe cardiac toxicity in zebrafish, which can be partially alleviated by the antioxidant astaxanthin, indicating oxidative stress as a key mechanism in bifenazate-induced cardiotoxicity.

Summary: Carboxin exhibits developmental and cardiotoxicity in zebrafish embryos, causing structural changes in the heart and disruption of heart developmental gene expression. Additionally, Carboxin induces oxidative stress and accumulation of reactive oxygen species (ROS) in zebrafish embryos, leading to mitochondrial damage and decreased ATPase activities. Carboxin also inhibits myocardial cell proliferation and decreases the number of blood cells in the heart, resulting in embryo death.

Summary: The study revealed that ethoprophos exposure can cause cardiac defects in zebrafish embryos, such as low heart rate, pericardium edema, and long SV-BA distance, while not affecting vascular development. This indicates that oxidative stress and inhibition of the wnt signaling pathway are the molecular mechanisms underlying ethoprophos-induced injury in zebrafish.

Summary: This study investigated the effects of areca nut alkaloids on zebrafish embryonic development and motor behavior. It was found that exposure to these alkaloids resulted in dose-dependent changes in zebrafish larvae, including increased malformation rate and decreased swimming activity. Additionally, oxidative stress and transcriptome analysis revealed potential mechanisms underlying these effects. These findings contribute to the risk assessment and early warning of areca nut alkaloid exposure.

Summary: This study evaluated the ecological impact of O-phenylphenol (OPP) using a zebrafish model, and found that OPP exposure leads to early disorder in craniofacial development and behavioral abnormalities in zebrafish. Furthermore, OPP exposure induces reactive oxygen species production, oxidative stress, and reduces the proliferation of cranial neural crest stem cells (NCCs). Astaxanthin (AST), an antioxidant, partially rescues OPP-induced craniofacial cartilage development abnormalities.

Summary: The principle of radiotherapy is to kill cancer cells while minimizing harm to non-cancer cells. Ferroptosis has been proposed as a new mechanism of radiation-induced cell death. This study demonstrated that Hemin, an iron overload agent, enhances reactive oxygen species (ROS) generation induced by ionizing radiation in lung cancer cells, leading to ferroptosis. Hemin also protected normal lung cells against radiation-induced cell death.

Summary: This paper reviews the role of radiation-induced rescue effect (RIRE) in radiation field size effect. It discusses the relationship between the biological effects of ionizing radiation and the size of the irradiated area. RIRE refers to the mitigation of detrimental effects in irradiated cells after receiving signals from non-irradiated bystander cells or from previously conditioned bystander cells. The paper provides a brief overview of RIRE, including its definition, classification, signalling pathways, and chemical messengers, and also reviews selected literature on radiation field size effects. It concludes with a discussion on the future research priorities and directions of RIRE in radiation field size effect.

Summary: Understanding the utilization of healthcare resources and its associated costs is crucial for improving resource allocation, but little research has been conducted on this issue in the setting of Brugada syndrome (BrS). In this retrospective study of BrS patients in Hong Kong, the healthcare resource utilization for accident and emergency, inpatient, and specialist outpatient visits was analyzed over 19 years. The median annual costs were $110 for accident and emergency visits, $6812 for inpatient stays, and $557 for specialist outpatient visits.

Summary: This paper introduces an open-source graphical user interface (GUI) computer program called DynamicMC, which can generate an ORNL phantom input script for the Monte Carlo N-Particle (MCNP) package. The program can simulate the relative dynamic movement of the radiation source with respect to the ORNL phantom, similar to the movement of source-to-target (i.e., human phantom) distance in a 3-dimensional radiation field. It simplifies the organ-based dosimetry of the human body and can be used as a teaching tool for nuclear radiation physics and its interaction with the human body.

Summary: The detrimental effects of 137Cs soil contamination on human health were investigated. A general decrease in 137Cs concentration in soil samples was observed in 2018, although variations were found at different locations. The study also showed no significant difference in estimated equivalent dose rate per unit activity of 137Cs between ICRP and ORNL phantom models. Two open-source computer programs were developed to provide users with an easy-to-use interface and portable tools to determine dosimetric quantities.

Summary: Estrogenic endocrine disrupting chemicals (EEDC) can impact offspring in a transgenerational manner through modifications of the germline epigenome. Exposure to EE2 during parental gametogenesis and embryogenesis can induce transgenerational reproductive effects and phenotype persistence in unexposed offspring. EE2 exposure also leads to feminization and subsequent masculinization of directly exposed generations. While reproductive output is more sensitive in females, immune competence is not significantly affected. These findings highlight the potential transgenerational toxicity of EEDCs and the negative impact on fish population sustainability.

Summary: Radiation-induced intestinal injury (RIII) is a common complication of radiotherapy, seriously affecting patients' quality of life. This study found that ferroptosis plays a critical role in RIII, with increased levels of lipid peroxidation markers. In vivo experiments demonstrated that the ferroptosis inhibitor improved the survival rate and alleviated intestinal fibrosis in mice. It was also found that arachidonic acid enhanced ferroptosis in cultured intestinal epithelial cells and aggravated RIII. Mechanistic studies revealed that the level of ACSL4 protein increased after irradiation, regulated by the STAT1/IRF1 axis, while AMPK activation triggered by AA negatively regulated radiation-induced ferroptosis.

Summary: Existing methods for monitoring radionuclides in aquatic environments are often impractical due to the need for frequent sampling and tedious analytical procedures. This study explored the feasibility of using 'Artificial Mussels' (AMs) as a new tool for radionuclide monitoring in marine environments. Results showed that AMs could effectively accumulate U-238, Sr-88, and Cs-133 from water, reaching equilibrium within 7 to 8 weeks with high concentration factors. These findings suggest that AMs can overcome the limitations of existing methods and offer a practical solution for radionuclide monitoring.
