Copper (Cu) is considered one of the major heavy metal pollutants in agriculture, leading to reductions in crop yield. To reveal the molecular mechanisms of resistance to copper stress in maize ( L.) seedlings, transcriptome analysis was conducted on the hybrid variety Zhengdan 958 exposed to 0 (control), 5, and 10 mM Cu stress using RNA-seq. In total, 619, 2,685, and 1,790 differentially expressed genes (DEGs) were identified compared to 5 mM versus 0 mM Cu, 10 mM versus 0 mM Cu, and 10 mM versus 5 mM Cu, respectively. Functional categorization of DEGs according to Gene Ontology revealed that heme binding, defense response, and multiorganism processes were significantly enriched under copper stress. Additionally, Kyoto Encyclopedia of Genes and Genomes enrichment analysis suggested that the copper stress response is mediated by pathways involving phenylpropanoid biosynthesis, flavonoid biosynthesis, and glutathione metabolism, among others. The transcriptome data demonstrated that metabolite biosynthesis and glutathione metabolism play key roles in the response of maize seedlings to copper stress, and these findings provide valuable information for enhancing copper resistance in maize.

Due to the rapid increase in industrial and urban areas, environmental pollution is increasing worldwide, which is causing unwanted changes in air, water, and soil at biological, physical, as well as chemical levels that ultimately causing the negative effects in living things because of toxic level of chromium (Cr). However, nanotechnology is capturing great interest worldwide due to their stirring applications in various fields. For this purpose, a pot experiment was conducted to examine plant growth and exo-physiology in rice (Oryza sativa L.

Background: Insufficient evidence is available to confirm the effect of exposure to airborne metals on mental disorders, particularly among asthmatics. We aimed to investigate the effect of airborne metal exposure on mental health responses in asthmatics and the general population.
Methods: Using nationally representative cross-sectional data, a total of 47,796 adults were analyzed.

Trace elements (TEs) are essential for human health and for maintaining immune responses against potentially aggressive pathogens, such as the human immunodeficiency virus (HIV). During the infectious process, the body needs greater amounts of TEs in order to coordinate an efficient immune response to combat the invading agent, a condition that reflects in lymphocyte proliferation and activation of the antioxidant defense system of neutrophils and macrophages. Thus, during the progression phase of a viral infection, immunomodulation of TEs such as iron, zinc, chromium, magnesium, selenium, copper, calcium, and manganese occurs, can lead to immunosuppression and increased oxidative stress.
