Summary: The study investigated the integrated influence of pollutant concentrations on phytoremediation efficiency by aquatic macrophytes. Results showed that COD removal efficiency increased with pollutant concentration, while TN, NH4+-N and TP purification efficiencies were inhibited at high concentration levels. Physiological responses in submerged macrophytes were explored to estimate the correlation between them and pollutant concentrations, with oxidative stress proved by higher MDA content. Antioxidant enzyme responses were induced to maintain plant health, but were inhibited in high pollutant concentration levels, leading to unhealthy symptoms in plants. The study concludes that excessive concentrations of organics and nutrients may inhibit adaptive physiological regulations and reduce phytoremediation efficiency.

Summary: This study analyzed the accumulation of 4-hydroxynonenal (4-HNE) in hepatocellular carcinoma (HCC) and its clinicopathological significance. The results showed that relatively low levels of 4-HNE accumulation were an independent prognostic predictor in HCC tissues. Additionally, the study found that the SMARCA4 gene regulates 4-HNE metabolism in HCC, suggesting that targeting SMARCA4 could be a new therapeutic strategy for HCC.

Summary: Marine pollution from anthropogenic sources poses a growing problem for natural species. Sharks, being top predators and consuming polluted animals, are at risk of water contamination and subsequent bioaccumulation and biomagnification. The present study investigated the accumulation of trace elements and their potential impact on oxidative processes in the muscle of the lesser spotted dogfish. The results indicated that trace element accumulation in sharks may disrupt oxidant and antioxidant processes, with significant implications for their physiology and health.

Summary: The study evaluated the stress response in Vigna radiata caused by metribuzin and explored the ameliorative role of exogenous application of plant growth regulators (PGRs) by assessing important biochemical and yield parameters. The results showed that metribuzin treatment resulted in increased lipid peroxidation and decreased chlorophyll and carotenoid contents as well as yield parameters in V. radiata plants. However, proline accumulation and activity of antioxidant enzymes were induced in metribuzin-treated plants. Exogenous application of GA, IAA, and SA significantly reduced lipid peroxidation and increased contents of photosynthetic pigments, proline, and antioxidant enzymes, thereby improving yield parameters. Among the three exogenously applied PGRs, SA exhibited the best ameliorative response during metribuzin stress, while the combined use of all PGRs greatly improved the biochemical and yield parameters of plants.

Summary: This study aimed to investigate the protective role of vitamin E in improving cardiotoxicity induced by cyclophosphamide in rats. The results showed that vitamin E could attenuate the elevation of cardiac markers, increase in lipid profiles, reduction in antioxidant enzyme activities, and increase in lipid peroxidation. In addition, vitamin E was found to improve the histopathological alterations caused by cyclophosphamide.

Summary: Cyanobacterial harmful algal blooms are a global issue that negatively impacts the aquatic environment and human health. This study discovered that the bacterium Stenotrophomonas sp. KT48 exhibited strong algicidal activity against Microcystis aeruginosa, a type of cyanobacteria. The algicidal activity was mainly attributed to direct attack on M. aeruginosa cells, rather than the excretion of algicides. Additionally, the study found that the bacterium increased the production of reactive oxygen species and lipid peroxidation in the algal cells, leading to inhibition of the antioxidant system. These findings provide insights into the potential use of strain KT48 as a bacterial agent for the control of cyanobacterial blooms.

Summary: As a rising generation of nanozymes, single atom enzymes show promise for cancer therapy due to their maximum atom utilization efficiency and well-defined electronic structures. This study develops an anion exchange strategy to produce a heteroatom-doped single atom enzyme with precise control, specifically sulfur (S)-and nitrogen (N)-decorated nickel single atom enzyme (S-N/Ni PSAE). The sulfurized S-N/Ni PSAE exhibits enhanced peroxidase-like and glutathione oxidase-like activities, triggering ferroptosis of tumor cells more effectively in vitro and in vivo compared to nitrogen-monodoped N/Ni PSAE.

Summary: The potato is a widely cultivated and consumed crop worldwide, with its economically valuable swollen stolonic region containing abundant carbohydrates and modest quantities of minerals and vitamins. Tuber formation is regulated by various factors, including light, oxygen concentration, photosynthate availability, phytochromes, transcription factors, and metabolite availability. This review provides an update on our understanding of the involvement of these variables in the process of tuberization. Tuber formation starts at the beginning of the supportive season under optimal light conditions, where phytochromes in leaves perceive the signal and trigger a series of reactions leading to starch accumulation in the tuber.

Summary: This study investigated the use of copper oxide nanoparticles (CuO NPs) as seed primers to enhance the growth of Brassica juncea. The results showed that seed priming with 4 mg/L CuO NPs for 30 minutes significantly increased the growth indices and biochemical parameters of B. juncea. Antioxidant enzyme activity and biochemical parameters were also enhanced. This suggests that CuO NPs can effectively improve the performance of B. juncea and may have potential in other crop species.
