    Abstract Volatile organic compounds (VOCs) are typical air pollutants as well as gaseous wastes that contain energy. Utilization and disposition of VOCs is currently an important research hotspot in the field of atmospheric environment. In this paper, the thermal cracking and oxidation reaction processes of typical VOCs components were modelled and analyzed by combining molecular dynamics and detailed reaction mechanisms, focusing on the effects of temperature, oxygen and other conditions on the conversion of VOCs. The results of molecular dynamics studies show that improving temperature and reaction time benefit the decomposition of VOCs. High temperatures under an inert atmosphere can sufficiently crack the VOCs themselves, but other by-products are generated, which in turn cause secondary pollution. The activation energies derived by ReaxFF-MD calculation are 328 kJ mol

    Abstract The RNA-binding proteins (RBPs) are critical trans factors that associate with specific cis elements present in mRNAs whose stability and translation are subject to regulation. The RBP Hu antigen R (HuR) is overexpressed in a wide variety of human cancers and serves as a prognostic factor of poor clinical outcome. HuR promotes tumorigenesis by interacting with a subset of oncogenic mRNAs implicated in different cancer hallmarks, and resistance to therapy. Reduction of HuR levels in cancer cells leads to tumor regression in mouse xenograft models. These findings prompt a working model whereby cancer cells use HuR, a master switch of multiple oncogenic mRNAs, to drive drug resistance and promote cell survival and metastasis, thus rendering the tumor cells with high cytoplasmic HuR more progressive and resistant to therapy. This review summarizes the roles of HuR in cancer and other diseases, therapeutic potential of HuR inhibition, and the current status of drug discovery on HuR.

    Abstract Advanced glycation end-products (AGEs) can boost their receptor of AGE (RAGE) expression through the downstream signaling pathway to facilitate AGE-RAGE interaction. In this regulation process, the primary signaling pathways are NF-κB and STAT3. However, the inhibition of these transcription factors cannot completely block the upregulation of RAGE, which indicates AGEs may also impact RAGE expression

    Abstract Background: The impact of hypertensive disorders of pregnancy (HDP) on outcomes of twin gestations is not clear. We aimed to collate data via this meta-analysis to examine how HDP alters maternal and neonatal outcomes of twin gestations.
    Methods: Studies comparing pregnancy outcomes of twin gestations based on HDP and published on the databases of PubMed, CENTRAL, Scopus, Web of Science, and Embase between 1 January 2000 to 20 March 2023 were eligible for inclusion.
    Results: Twelve studies were included. A cumulative of 355,129 twin gestations were analyzed in the current meta-analysis. The pooled analysis found that the presence of HDP increases the risk of preterm birth (OR: 1.86 95% CI: 1.36, 2.55
    Conclusion: HDP increases the risk of preterm birth, cesarean sections, low birth weight, SGA, and NICU admission in twin gestations. Contrastingly, the risk of neonatal death is reduced with HDP. Further studies are needed to corroborate the current results.

    Abstract Background: Nucleolar prominence is a biomarker of prostate cancer (CaP), and the nucleolar protein block of proliferation 1 (BOP1) participates in the development of CaP, which has great significance for CaP therapy. Thus, this study explored the mechanism of BOP1 in CaP development.
    Methods: BOP1 expression levels in the tumor tissues of CaP patients and in PC3 tumor cells were determined. The viability, apoptosis rate of PC3 cells, and apoptosis-related proteins levels were determined to explore the effect of BOP1 on tumor-cell growth
    Results: BOP1 expression was upregulated in the tumor tissues and PC3 cells of CaP patients. BOP1 knockout reduced the activity of PC3 cells and induced apoptosis, significantly inhibiting the metastasis of PC3 cells. DUSP6 was overexpressed in tumor tissues and PC3 cells. BOP1 knockout inhibited DUSP6 expression and the MAPK pathway. DUSP6 overexpression reversed the inhibition of BOP1 siRNA (si-BOP1) on PC3 cells and the activated MAPK signaling pathway.
    Conclusions: This finding demonstrated that BOP1 promoted CaP progression by regulating the DUSP6/MAPK pathway.

    Abstract Epigallocatechin-3-O-gallate is natural phytochemical of green tea. RAGE upregulation promotes osteoarthritis (OA) progression. Herein, we revealed that EGCG can repress RAGE expression epigenetically to ameliorate OA. Firstly we found that RAGE expression was dose-dependently reduced by EGCG on chondrocyte cell C28/I2. EGCG also suppressed RAGE in human primary OA chondrocytes, and accordingly attenuated ROS production and NF-κb activity. Osteoarthritic microenvironment was also improved by EGCG, which was reflected by the enhanced chondrogenic markers and reduced inflammatory markers. EGCG-induced ameliorations were counteracted by artificial overexpression of RAGE. Additionally, EGCG modulates RAGE expression not only by its antioxidant activity, but also by facilitating RAGE promoter hypermethylation. To confirm this epigenetic modification, we employed dCAS9-Tet1 against EGCG’s epigenetic regulation. RAGE level was correspondingly rescued after EGCG-induced hypermethylation status were blocked. These findings support therapeutic roles of EGCG on OA and uncover the novel molecular mechanism of EGCG-mediated RAGE modulation.

    Abstract Fouling of landfill leachate, a biofilm formation process on the surface of the collection system, migration pipeline and treatment system causes low efficiency of leachate transportation and treatment and increases cost for maintenance of those facilities. In addition, landfill leachate fouling might accumulate pathogens and antibiotic resistance genes (ARGs), posing threats to the environment. Characterization of the landfill leachate fouling and its associated environmental behavior is essential for the management of fouling. In this study, physicochemical and biological properties of landfill leachate fouling and the possible accumulation capacity of pathogens and ARGs were investigated in nitrification (aerobic condition) and denitrification (anaerobic condition) process during landfill leachate biological treatment, respectively. Results show that microbial (bacterial, archaeal, eukaryotic, and viral) community structure and function (carbon fixation, methanogenesis, nitrification and denitrification) differed in fouling under aerobic and anaerobic conditions, driven by the supplemental leachate water quality. Aerobic fouling had a higher abundance of nitrification and denitrification functional genes, while anaerobic fouling harbored a higher abundance of carbon fixation and methanogenesis genes. Both forms of leachate fouling had a higher abundance of pathogens and ARGs than the associated leachate, suggesting the accumulation capacity of fouling on biotic pollutants. Specifically, aerobic fouling harbored three orders of magnitude higher multidrug resistance genes mexD than its associated leachate. This finding provides fundamental knowledge on the biological properties of leachate fouling and suggests that leachate fouling might harbor significant pathogens and ARGs.

    Abstract Anthriscus sylvestris (L.) Hoffm. Gen. is a biennial or perennial herb commonly found in China. It has a long history of use in traditional Chinese medicine to treat various ailments such as cough, gastric disorders, spleen deficiency, and limb weakness. Recently, its potential as an anticancer agent has gained considerable attention and has been the subject of extensive research focusing on extract efficacy, identification of active compounds, and proposed molecular mechanisms. Nevertheless, further high-quality research is still required to fully evaluate its potential as an anticancer drug. This review aims to comprehensively summarize the anticancer properties exhibited by the active components found in Anthriscus sylvestris. We conducted a comprehensive search, collation, and analysis of published articles on anticancer activity and active compounds of A. sylvestris using various databases that include, but are not limited to, PubMed, Web of Science, Science Direct and Google Scholar. The primary chemical composition of A. sylvestris consists of phenylpropanoids, flavonoids, steroids, fatty acids, and organic acids, showcasing an array of pharmacological activities like anticancer, antioxidant, anti-aging, and immunoregulatory properties. Thus, this review highlights the active compounds isolated from A. sylvestris extracts, which provide potential leads for the development of novel anticancer drugs and a better understanding of the plant's pharmacological effects, particularly its anticancer mechanism of action.
