Summary: This study explored the potential of Spinacia oleracea L. leaf aqueous extract green-mediated gold nanoparticles (AuNPs) in the treatment of endometrial cancer. Through a series of experiments and tests, it was found that the AuNPs had good physicochemical properties and antioxidant properties, and showed significant inhibitory effects on endometrial cancer cell lines. The importance of S. oleracea leaf extract-mediated AuNPs as an anti-endometrial cancer material was validated.

Summary: Research on spinach dioecy identified a male-specific region on chromosome 4, potentially linked to the male-determination gene. A KASP marker, SponR, developed from a SNP closely linked to the MSR, co-segregated with the sex determination gene in a population of approximately 958 individuals.

Summary: The aim of this study was to investigate the effect of thiol species on the high cadmium tolerance of spinach and provide information for improving soil utilization. The results showed that as cadmium stress increased, the cadmium concentrations in spinach tissues also increased. Glutathione (GSH) and phytochelatins (PCs) played important roles in response to cadmium stress. Negative correlations were observed between GSH and cadmium concentrations in roots, as well as between changes in PC3 and concentrations of cadmium in leaves. Thiol production can occur in different tissues of spinach, while the shoots mainly serve as a transport tissue for GSH.

Summary: The study aims to partially replace intensive mineral fertilizers with bio-fertilizers by supplementing 50% of the mineral fertilizers with Chlorella vulgaris microalgae, beneficial bacteria, and mycorrhiza. The research findings demonstrate that the use of bio-fertilizers significantly improves the quality of hydroponically grown baby spinach and reduces reliance on mineral fertilizers.

Summary: This study conducted QTL mapping of leaf-related traits in spinach and identified five repeatedly detected QTLs for leaf-related traits. The major QTLs of leaf length, petiole length, and the ratio of leaf length to width were mapped on the same loci. Three genes were identified as important candidate genes for leaf width.

Summary: This research focuses on the manufacture of copper oxide nanoparticles using Spinacia oleracea leaf extract in an aqueous medium. Various analytical methods were used to identify the structure of the CuO nanoparticles, and it was found that they exhibited significant bactericidal and antifungal activities, as well as larvicidal activity towards Culex Quinquefasciatus. The study concludes that CuO can be synthesized in a simple and environmentally friendly manner, and has a wide range of uses.

Summary: This study explores the possibility of an automatic detection system to prevent co-harvesting of poisonous weeds with crops, which poses a threat to human health. The results show that Phaseolus vulgaris and Spinacia oleracea can be distinguished from Solanum nigrum, Solanum tuberosum, and Datura stramonium using spectrometer measurements. The influence of different populations, varieties, and conditions on classification is relatively small. However, the selected wavelength regions showed inconsistency when using data from consecutive years, suggesting the need for careful sample selection. The use of commercial off-the-shelf filters and high resolution RGB cameras is recommended for further research.

Summary: This study investigated how metal toxicity affects the oxygen-evolving complex in spinach, specifically the coordination structure of the Mn4CaO5 cluster in photosystem II. The presence of Cu2+ and Pb2+ disrupted the essential chloride ions, leading to impaired oxygen release. Additionally, the accumulation of these metals altered the leaf structure, reducing stomatal opening and pigment concentration, ultimately impacting photosynthesis and plant growth.

Summary: The study evaluates the distributions of total PM2.5 of different sizes in New Delhi, India over 12 months and finds that ultrafine particles significantly contribute to total PM2.5 and are most cytotoxic to human lung epithelial cells. In March, higher amounts of reactive oxygen species are generated per unit mass for all sizes of PM, without correlation to metal content values.
