Background Cadmium(Cd) pollution in agricultural soils has become a priority environmental concern globally. A reasonable application of passivators is critical to address the problem. In this study, we examined the remediation effects of rice husk biochar(r BC) and sepiolite(Sep) as single and combined(r BC + Sep) treatments on Cd pollution in a weakly alkaline soil using three maize cultivars(Liyu 16, Zhengdan 958, and Sanbei 218) as test crops. We also explained the mechanisms involved in the remediation *** The pseudo-second-order kinetic equation and Langmuir model could well describe the adsorption process of r BC + Sep for Cd2+. Compared with the control treatment(CK), soil available Cd concentration decreased by 29.51–36.34% under r BC + Sep treatment(p 0.05).Conclusions The application of 0.2% r BC + 0.5% Sep composite passivation material to weakly alkaline Cd-contaminated soil can effectively reduce the Cd concentration of soil and maize.

Porcine enteric alphacoronavirus infection increases lipid droplet accumulation to facilitate the virus replication

Journal of Integrative agriculture 2024年第3期23卷 988-1005页

作者： Qi Gao Yongzhi Feng Ting Gong Dongdong Wu Xiaoyu Zheng Yizhuo Luo Yunlong Yang Zebu Song Lang Gong Guihong Zhang Guangdong Provincial Key Laboratory of Zoonosis Prevention and Control College of Veterinary MedicineSouth China Agricultural UniversityGuangzhou 510642China Maoming Branch Guangdong Laboratory for Lingnan Modern AgricultureMaoming 525000China Key Laboratory of Animal Vaccine development Ministry of Agriculture and Rural AffairsGuangzhou 510000China Guangdong Laboratory for Lingnan Modern agriculture Guangzhou 510642China

Coronaviruses are widely transmissible between humans and animals, causing diseases of varying severity. Porcine enteric alphacoronavirus(PEAV) is a newly-discovered pathogenic porcine enteric coronavirus in recent years, which causes watery diarrhea in newborn piglets. The host inflammatory responses to PEAV and its metabolic regulation mechanisms remain unclear, and no antiviral studies have been reported. Therefore, we investigated the pathogenic mechanism and antiviral drugs of PEAV. The transcriptomic analysis of PEAV-infected host cells revealed that PEAV could upregulate lipid metabolism pathways. In lipid metabolism, steady-state energy processes, which can be mediated by lipid droplets(LDs), are the main functions of organelles. LDs are also important in viral infection and inflammation. In infected cells, PEAV increased LD accumulation, upregulated NF-κB signaling, promoted the production of the inflammatory cytokines IL-1β and IL-8, and induced cell death. Inhibiting LD accumulation with a DGAT-1 inhibitor significantly inhibited PEAV replication, downregulated the NF-κB signaling pathway, reduced the production of IL-1β and IL-8, and inhibited cell death. The NF-κB signaling pathway inhibitor BAY11-7082 significantly inhibited LD accumulation and PEAV replication. Metformin hydrochloride also exerted anti-PEAV effects and significantly inhibited LD accumulation, downregulated the NF-κB signaling pathway, reduced the production of IL-1β and IL-8, and inhibited cell death. LD accumulation in the lipid metabolism pathway therefore plays an important role in the replication and pathogenesis of PEAV, and metformin hydrochloride inhibits LD accumulation and the inflammatory response to exert anti-PEAV activity and reducing pathological injury. These findings contribute new targets for developing treatments for PEAV infections.
