Rice is an important agricultural product consumed globally. Rice polluted by cadmium (Cd) poses serious health risks. Numerous studies have shown that arbuscular mycorrhizal fungi (AMF) decrease Cd concentrations in the grain, shoots, and roots of rice. However, one study showed that AMF increased the root Cd concentration in rice. Therefore, a meta-analysis of the contribution of AMF to rice Cd tolerance became necessary. This meta-analysis was conducted to analyze the role of AMF in Cd tolerance in rice by searching the following databases: ProQuest, PubMed, Scopus, and ScienceDirect. A total of 571 studies were found, of which nine studies and 25 datasets were used in the meta-analysis. The period of inclusion of research reports was from January 1992 to April 2022. The results showed that with the addition of Rhizophagus irregularis, Cd concentration in the roots was higher than in the control group, although the overall Cd concentration in the plant was reduced. Four species of AMF reduced Cd concentration in rice shoots and grain tissues. These AMF species increased the biomass of rice root and shoot tissues; however, they did not affect grain biomass. AMF decreased the transfer factor (TF), and the TF of Glomus versiforme (12.99%) was significantly lower than the other three AMF types. We proposed that Cd could be enriched in rice roots, and the transfer of Cd to the grain could be inhibited. At the time of grain harvesting, rice roots are removed from the soil, thus removing Cd from the soil. This operation can efficiently improve both land-bearing capacity and soil without affecting rice yield. Thus, Cd was enriched in rice roots, and the poten-tial for Cd transfer to the grain was inhibited due to the decreased TF. The future research must focus on how R. irregularis could improve the HMA3 gene expression in rice root, and prevents the transportation of Cd from the roots to shoots.

Pseudorabies virus (PRV) is an economically important viral agent affecting the swine industry in China. Accurate, rapid and simple detection is critical to PRV control and eradication. In the present study, a visible and low equipment-dependent recombinase-aid amplification assay integrated with lateral flow assay (RAA-LFA) was successfully developed to detect the PRV against the gE gene. The RAA-LFA did not react with the other swine pathogens, indicating the method has a good specificity. The limit of detection (LOD) for this RAA-LFA method was 21 copies per reaction against standard plasmids containing gE gene. Notably, the RAA-LFA can detect as low as 6.0 × 10

Studies and treatments of schizophrenia with cannabidiol (CBD) alone have been reported. However, there have been a variety of different results of the effects of CBD in schizophrenic patients based on the positive and negative syndrome scale (PANSS). Thus, the present meta-analysis aimed to determine the effects of CBD on schizophrenia. We searched internet databases and identified 774 potentially relevant studies, among which nine studies were ultimately included in our present meta-analysis. Our results showed that CBD treatments significantly decreased PANSS positive scores (95% CI, −2.51, −0.89, P = 0.27, I2 = 18%) but had no effect on other PANSS scores. Interestingly, while the safety of CBD has continued to be further demonstrated over time despite the dosage of CBD being gradually increased, the dosage of delta-9-tetrahydrocannabinol (THC) has remained essentially unchanged. Following our present meta-analysis, we suggest possible mechanisms of CBD-based amelioration of schizophrenic symptoms, such as CBD-induced increases in fronto-striato-thalamic coupling.

In this article, we study the large-time behavior of combination of the rarefaction waves with viscous contact wave for a one-dimensional compressible Navier-Stokes system whose transport coefficients depend on the temperature. It is shown that if the adiabatic exponent γ is suitably close to 1, the unique solution global in time to ideal polytropic gas exists and asymptotically tends toward the combination of a viscous contact wave with rarefaction waves under large initial perturbation. New and subtle analysis is developed to overcome difficulties due to the smallness of γ – 1 to derive heat kernel estimates. Moreover, our results extend the studies in a previous work [F. M. Huang, J. Li, and A. Matsumura, Arch. Ration. Mech. Anal. 197 (2010), no. 1, 89–116].

Avicennia marina is a pioneer salt-tolerant plant in coastal intertidal mangroves, an efficient blue carbon ecosystem. It is of great importance to explore how salinity affects the phyllosphere and rhizosphere microbial communities of A. marina. This study showed that the microbial communities in the phyllosphere and rhizosphere of A. marina had different constitutive properties, adaptive network interactions, and potential stress-promoting functions.

PRV belongs to the alphaherpesvirus and has recently re-emerged in China, causing severe economic losses. Recent studies also indicate that PRV may pose a potential public health challenge.
