TL;DR: Wang et al. as mentioned in this paper built a data model processing system based on the event analysis method, and analyzed the shock effect from three aspects of supply chain finance, financial securities, and corporate financial systems.
Abstract: The Corona Virus Disease 2019(COVID-19) has a dramatic effect on my country's market and financial system. Although China has controlled the deterioration of the epidemic, this global epidemic will inevitably have an impact on the global economy including China. In order to study the shock effect of the COVID-19 on the market financial system, this paper builds a data model processing system based on the event analysis method, and analyzes the shock effect from three aspects of supply chain finance, financial securities, and corporate financial systems. Moreover, this paper uses crawler technology to obtain valid data from major websites, analyzes model data with mathematical statistics combined with event models, and outputs the results and compares them with the actual situation. Through data analysis, it can be seen that the model constructed in this paper can effectively reflect the shock effect of the COVID-19 on the market financial system. Finally, the comparison method is used to compare the research results with the actual situation. The results show that the two are basically the same. Therefore, it can be seen that the proposed research method has significant effects and has certain reference value for studying the shock effect of the epidemic on the financial system.
TL;DR: In this paper, the inhibitory potency of heptanal, a natural volatile chemical, against Aspergillus flavus growth was evaluated, and its mechanism of action was explored.
Abstract: Fungal contamination poses a threat to agriculture, food production and human health, and a safe and effective method to limit fungal contamination is still needed. In this study, the inhibitory potency of heptanal, a natural volatile chemical, against Aspergillus flavus growth was evaluated, and its mechanism of action was explored. The minimum inhibitory concentrations (MICs) of heptanal vapor fumigation and liquid contact culture were 0.085 and 0.8 μL/mL, respectively. A total of 79 significant differentially abundant metabolites, including 37 upregulated and 42 downregulated ones, were identified in A. flavus mycelia after exposure to 0.8 μL/mL heptanal for 6 h. Metabolomics analysis revealed that heptanal had destructive effects on plasma integrity and mitochondrial function in mycelia. Biochemical analysis confirmed that heptanal caused intracellular substance leakage and resulted in reduced intracellular ATP content, reactive oxygen species (ROS) accumulation, and lower mitochondrial dehydrogenase and ATPase activities. Evaluation of the control efficacy of heptanal fumigation on wheat grain under simulated storage conditions revealed that 225.0 μL/L heptanal vapor could inhibit A. flavus growth under 19% moisture. These results provide insights into the antifungal mechanism of heptanal against A. flavus growth as a promising bio-preservative.

TL;DR: In this article, the effects of the surface tension, conductivity, and viscosity of the PPI/PLLA solution on nanofiber morphology were investigated, and the results indicated that PPI and PLLA molecules interact by forces such as hydrogen bonding and PPI disrupts the ordered molecular arrangement of the poly- l -lactic acid (PPI) molecules, thereby reducing the crystallinity of the nanofibers while improving their thermal stability.
Abstract: Peanut protein isolate (PPI) is bio-friendly, degradable, and may be obtained from a wide range of sources. In this study, hexafluoroisopropanol solutions of PPI and poly- l -lactic acid (PLLA) were electrospun to prepare nanofibers. The effects of the surface tension, conductivity, and viscosity of the PPI/PLLA solution on nanofiber morphology were investigated. Furthermore, the PPI/PLLA nanofibers were thoroughly characterized using a range of techniques. The results revealed that as the PPI content of the solution increases, its apparent viscosity decreases, its conductivity increases, and the diameter of the nanofibers is reduced from 339 nm to 164 nm. At a PPI/PLLA mass ratio of 50:50, the fiber morphology is good, no beading is observed, and the fiber diameter is uniform. In mechanistic terms, our results indicated that PPI and PLLA molecules interact by forces such as hydrogen bonding, and that PPI disrupts the ordered molecular arrangement of the PLLA, thereby reducing the crystallinity of the nanofibers while improving their thermal stability. Furthermore, as the mass fraction of PPI increases, the tensile strength of the nanofibers decreases while their hydrophobicity increases. Overall, this study has successfully realized the preparation of PPI nanofibers, providing a basis for their application in biomedicine, catalysis, and other fields.
