Summary: In this study, ducks were used to mimic arsenic trioxide (ATO) exposure and investigate its mechanism of cardiac toxicity. The results showed that ATO inhibited body and organ growth, increased LDH levels, and caused deformity and ischemia infarction in ducks. Transmission electron microscopy revealed that ATO exacerbated mitochondrial swelling and cell nuclei contraction in the duck heart. ATO also induced oxidative stress and apoptosis, via the Nrf 2/Caspase 3 signaling pathway, by altering the expression levels of various genes and proteins related to apoptosis and oxidative stress.

Summary: Exploiting non-covalent interactions to catalyze ionic polymerizations is still in its early stages. A recent study demonstrated non-covalent anion-binding catalysis for living cationic polymerization of vinyl ethers. This study further investigates the structure-reactivity relationships and roles of anion-binding interactions in the catalytic process. The findings provide insights into the mechanism of anion-binding catalytic polymerization and offer guidance for future catalyst design.

Summary: A series of modified N-doped Nb2O5 catalysts were prepared by using a modular calcination strategy combining hydrogen, vacuum, air, and ammonia modules. Among these modified catalysts, HN-Nb2O5 showed the best photocatalytic performance for the photo-oxidation of cyclohexane. The outstanding performance can be attributed to the abundant chemical defects of oxygen vacancies and Nb4+, as well as the presence of NOx species, which enhanced light absorption and effective electron-hole separation.

Summary: A flexible self-consistent field method called target state optimization (TSO) is introduced, which can explore electronic excited configurations and localized diabatic states. The TSO method partitions molecular orbitals into different subspaces based on the excitation or localization pattern of a target state, allowing for variationally optimized excited or diabatic configurations without collapsing back to the ground state. TSO-DFT has been shown to outperform conventional TD-DFT calculations for core excitation, doubly excited states, and charge-transfer states.

Summary: This study investigated the effects of Curcumae Longae Rhizoma (CLR) extract on angiogenesis and found that it significantly suppressed angiogenic responses such as proliferation, migration, invasion, and tube formation of endothelial cells. It also reduced subintestinal vessel formation in a zebrafish embryo model. Mechanistically, CLR extract inhibited the VEGF-triggered signaling pathway, decreased phosphorylated VEGFR2 levels, and inhibited downstream regulators. It also reduced the production of NO and ROS. Additionally, CLR extract suppressed cell migration and NF-Kappa B translocation in cancer cells.

Summary: This paper introduces a kind of X100 pipeline steel with a multiphase structure of bainite and fine M/A constituent, which has high strength, toughness, and excellent plasticity. The Heating on-line partitioning (HOP) process is used to achieve the multiphase structure by diffusing carbon atoms from bainite to austenite, improving austenite stability and increasing the volume fraction of retained austenite. The widening of bainite laths and the decrease in dislocation density increase the plasticity, while carbides precipitation and martensite formation provide the steel with high strength.

Summary: A multistate energy decomposition analysis (MS-EDA) method is introduced to analyze the energy components in molecular complexes in excited states. It partitions the total binding energy of an excimer or an exciplex into a ground-state term and excited-state contributions, providing quantitative insights into physical concepts such as exciton delocalization and superexchange charge-transfer effects. Based on the analysis, molecular complexes in excited states can be categorized into encounter excited-state complex, charge-transfer exciplex, and intimate excimer or exciplex. MS-EDA can serve as a useful tool for understanding photochemical and photobiological processes.

Summary: Developing high-efficiency and low-toxicity natural antifungal agents for green mold caused by Penicillium digitatum is urgent. MNQ-derived carbon dots (MNQ-CDs) were synthesized and used as antifungal agents against P. digitatum. MNQ-CDs showed enhanced antifungal activity compared to MNQ, with a minimum inhibitory concentration of 2.8 μg/mL. Omics data revealed that MNQ-CDs primarily modified the metabolism of aromatic amino acids and the synthesis of the cell membrane in P. digitatum, thereby inhibiting its propagation.
