Summary: This study investigates the role and mechanism of auxin in controlling rice's cadmium (Cd) accumulation. It is found that auxin reduces the hemicellulose content of rice root cell walls, leading to a decrease in Cd fixation and expression of genes related to Cd uptake. Moreover, auxin increases the expression of genes involved in Cd efflux and sequestration in vacuoles, resulting in less Cd accumulation in the shoots. Additionally, auxin reduces endogenous nitric oxide levels and antioxidant enzyme activity. Overall, this study reveals that auxin enhances rice's tolerance to Cd toxicity through the regulation of nitric oxide accumulation.

Summary: This study investigated the effects of nitric oxide (NO) on rice plants under lead (Pb) toxicity. The results showed that NO improved chlorophyll and proline metabolism, leading to enhanced growth and photosynthetic performance of rice plants under Pb stress. Additionally, NO reduced the accumulation of oxidative stress markers and promoted the immobilization of Pb in the roots. These findings suggest that NO could be a promising tool for enhancing the tolerance of rice plants to Pb toxicity.

Summary: Hormones like auxins and cytokinins play crucial roles in plant organ formation, with nitric oxide (NO) also being identified as a regulator in root architecture and shoot development. The interaction between NO and auxins has been found to impact various aspects of shoot architecture in Arabidopsis thaliana. Specifically, NO-associated 1 (NOA1) has been highlighted as a key player in NO production, while NO has been shown to regulate PIN1 accumulation, affecting auxin-mediated leaf development mechanisms.

Summary: This study proposed a new design strategy based on pi-conjugation modulation for fluorescent probes, which can generate different emission bands in the presence and absence of the target. The newly designed fluorescence probe, Rhod-DCM-B, exhibited outstanding sensitivity and excellent selectivity towards ONOO-. It was successfully employed to determine endogenous and exogenous ONOO- in living cells, and effectively monitored the ONOO- in vivo.

Summary: The results of the study indicate that 10 weeks of social isolation led to a significant decrease in PPI, accompanied by a decrease in NOS activity in the cerebral cortex and the cerebellum, an increase in iNOS in the hippocampus, and an increase in CD concentration in cortex homogenate. On the other hand, 29 weeks of social isolation had an opposite effect on NOS activity, with an increase in the cerebral cortex and the cerebellum in animals reared in a social environment, accompanied by a decrease in CD concentration.

Summary: A meta-analysis of 86 studies has shown that nitric oxide (NO) can significantly improve plant biomass, alleviate oxidative damage, and increase the content of Ca, Fe, and Mg in heavy metal-stressed plants. The optimal concentration of SNP (an NO donor) for hydroponic culture is in the range of 75-150 μM. These findings provide valuable insights for the future application of NO as a plant growth regulator for enhancing heavy metal stress tolerance in agriculture and breeding.

Summary: Nitric oxide (NO) is a crucial signaling molecule in plants, playing roles in regulating plant growth and development, and responding to stress. Cadmium (Cd) pollution is a widespread environmental hazard that inhibits plant growth and threatens human health. Plants have evolved mechanisms to cope with Cd stress, and NO is known to be involved in these responses. However, the mechanisms by which Cd stress affects the accumulation of endogenous NO in plants and the role of exogenous NO in plant responses to Cd stress remain unclear.

Summary: Chronic exposure to arsenic in drinking water can lead to myocardial injury and cardiomyocyte apoptosis through oxidative stress and a reduction in NO content. Rats exposed to different doses of sodium arsenite showed localized inflammatory foci and necrotic myocardial tissues with increasing concentrations of sodium arsenite. The activities and gene expression of antioxidant enzymes decreased, as well as NO content, NOS activity, and NOS mRNA expression in the myocardial tissue of exposed rats.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

Summary: This study investigates the impact of biochar on methylmercury (MeHg) accumulation in rice. The results show that biochar reduces MeHg levels in paddy soils by decreasing bioavailable Hg and microbial Hg methylation. Additionally, biochar decreases the uptake and translocation of MeHg in rice plants, resulting in a reduction of MeHg accumulation in rice grains.

The presence of magnetite resulted in increased concentrations of DBPs due to the higher microbial activity and enhanced microbial extracellular electron transport pathway. The study highlights the importance of considering trace antibiotics pollution and corrosion scales in water sources for DBP control.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
