Purification-analysis of urban rivers by combining graphene photocatalysis with sewage treatment improvement based on the MIKE11 model.

This study takes the Nanfei River as an example, using a hydrodynamic and water quality model based on MIKE11 to predict the effect of graphene photocatalysis on urban rivers. The effect of water quality improvement in the Nanfei River was simulated under three different scenarios (treatment plant upgrade, use of graphene photocatalytic oxidation technology, and a combination of both), and the results showed that implementing a graphene photocatalytic network could significantly improve water quality. The improvement of sewage treatment plants can also improve the water quality to a certain extent, improving the sewage treatment plants alone is insufficient.

Isobavachalcone inhibits Pseudorabies virus by impairing virus-induced cell-to-cell fusion.

Pseudorabies virus (PRV) is an important pathogen that threatens the global swine industry. Currently, there is no effective drug that can clinically prevent or treat PRV infections. Isobavachalcone (IBC), a natural chalcone compound derived from Psoralea corylifolia, displays multiple biological activities, such as antibacterial, antifungal, and anticancer activities.

Isobavachalcone inhibits post-entry stages of the porcine reproductive and respiratory syndrome virus life cycle.

Porcine reproductive and respiratory syndrome virus (PRRSV) is a pathogen of great economic significance that impacts the swine industry globally. Since the first report of a porcine reproductive and respiratory syndrome (PRRS) outbreak, tremendous efforts to control this disease, including various national policies and plans incorporating the use of multiple modified live-virus vaccines, have been made. However, PRRSV is still a significant threat to the swine industry, and new variants continually emerge as a result of PRRSV evolution.
