We have previously demonstrated the hepatoprotective effect of Schisandra chinensis polysaccharides (SCP) against the liver injury induced by alcohol, high-fat diet, and carbon tetrachloride in mice. In this study, we investigated the effect of SCP against the immunological liver injury induced by concanavalin A (Con A) in mice. The results showed that SCP could significantly reduce the level of alanine aminotransferase (ALT), aspartate aminotransferase (AST), tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in the serum of mice with immunological liver injury. SCP could significantly decrease the content of malondialdehyde (MDA) and nitric oxide (NO) and increase the activity of superoxide dismutase (SOD) and glutathione (GSH) in the liver tissue. SCP could significantly increase the number of CD4+ and decrease the number of CD8+ in the peripheral blood, and elevate the ratio of CD4+/CD8+. SCP could significantly downregulate the expression of Kelch-like ECH-associated protein 1 (Keap1) and upregulate the expression of nuclear factor-erythroid 2-related factor2 (Nrf2) and downstream gene heme oxygenase-1 (HO-1), and downregulate the expression of toll-like receptor 4 (TLR4), myeloid differentiation primary response gene 88 (MyD88), and nuclear factor-kappa B (NF-κB) proteins. This study indicates that SCP can reduce the release of a large number of inflammatory factors to inhibit the oxidative stress in mice with the immunological liver injury induced by Con A, and its mechanism is closely related to the regulation of Nrf2/antioxidant response element and TLR4/NF-κB signaling pathways.

Background High-throughput sequencing of blood cell-free DNA (cfDNA) techniques offer an opportunity to characterize and monitor cancer rapidly in a non-invasive and real-time manner. Nonetheless, there lacks a tool within therapeutic arsenal to identify multi-omics alterations simultaneously from a single biopsy. In current times, bisulfite-based sequencing detects 5mC and 5hmC at single-base resolution is the golden standard of DNA methylation, while the degradation of DNA and biased sequencing data are the problems of this method. Objective To identify the consistency analysis of methylation and genetic variation with single library, we presented a platform detecting multi-omics data simultaneously from a single blood biopsy using bisulfite-free method of genomic methylation sequencing (GM-seq) mediated by TET enzyme. Methods We detected methylomic and genetic changes simultaneously from a single blood biopsy in NA12878 and randomly chose ten blood biopsies from colorectal cancer or lung cancer patients to validate the ability of GM-seq. Results Similar cytosine methylation level between whole genome bisulfite sequencing (WGBS) and GM-seq were identified in NA12878. Moreover, longer insert size, CpGs coverage and GC distribution were outperformed than WGBS. In addition, the comparison of the single nucleotide polymorphism (SNP), insertion-deletion (Indel) and copy number variation (CNV) in NA12878 or ctDNA from liver cancer between GM-seq and whole genome sequencing (WGS) show a good consistency, indicating that this method is feasible for detecting genetic variation in blood. Conclusion In conclusion, our work demonstrated a method for identification of the methylated modification and genetic variations simultaneously from a single blood biopsy.

DFT study of the oxidation of Hg0 by O2 on an Mn-doped buckled g-C3N4 catalyst
Liu Shuai,Xu Mengxia,Chen Yipei,Mu Xueliang,Yu Jiahui,Yang Gang,Luo Xiang,Jiang Peng,Wu Tao 한국물리학회 2022 Current Applied Physics Vol.40 No.-
Due to the water-insoluble nature of Hg0, its oxidization to Hg2+, which is water-soluble, is a viable approach for its effective removal at coal-fired plants using existing flue gas desulfurization (FGD) unit. In this study, the adsorption and oxidation of elemental mercury on an Mn-doped g-C3N4 material were investigated. The spinpolarized density functional theory method was adapted to optimize the geometry structures and then to determine the corresponding electronic structures, while the CI-NEB method was adopted to search for the stable intermediates during the reaction(s). The analysis of energy and project density of states shows that the Mn-g- C3N4 exhibits an excellent affinity to Hg atoms. It is found that it is feasible for Hg atoms to oxidize on the Mn-g- C3N4 surface via two possible E-R paths, but with relatively high energy barriers. This research provides insights into a viable way for mercury removal using O2 as the oxidizing agent.
