Paeoniflorin inhibits APEC-induced inflammation in HD11 cells through the NF-κB signaling pathway by activating CBR.

Avian pathogenic Escherichia coli (APEC) is a bacterial pathogen that threatens poultry reproduction by inciting systemic inflammation and leading to chicken colibacillosis. The endocannabinoid system (ECS) is an immunomodulator system that regulates inflammatory responses. In this study, we aimed to investigate the anti-inflammatory effect of paeoniflorin on APEC-infected HD11 cells and its underlying mechanism.

Regulatory role and molecular mechanism of METTL14 in vascular endothelial cell injury in preeclampsia.

Preeclampsia (PE) is a pregnancy-related disease characterized by vascular endothelial cell injury. This study aimed to investigate the role of methyltransferase-like protein 14 (METTL14) in vascular endothelial cell injury in PE. The PE cell model was established by treating human umbilical vein endothelial cells (HUVECs) with tumor necrosis factor-alpha (TNF-α) in vitro.

Environment DNA Reveals Fish Diversity in a Canyon River within the Upper Pearl River Drainage.

Investigating fish diversity in canyon rivers through conventional fish surveys is challenging due to precipitous conditions, including steep slopes, rapid water flow, and complex habitats. Additionally, intensive construction of dams has further complicated the understanding of contemporary fish diversity in these rivers. In this study, we used the environmental DNA (eDNA) technique to assess fish diversity and examine the effects of dams on fish diversity in the Mabiehe River, a canyon river in the upper reaches of the Pearl River drainage.

A novel copper oxide/titanium membrane integrated with peroxymonosulfate activation for efficient phenolic pollutants degradation.

Herein, a novel CuO catalyst functionalized Ti-based catalytic membrane (FCTM) was prepared via the regulated electro-deposition technique followed with low-temperature calcination. The morphology of CuO catalyst and oxygen vacancy (O) content can be controlled by adjusting the preparation conditions, under optimal condition (400 °C, electrolyte as sulfuric acid), the fern-shaped CuO catalyst was formed and the O content was up to its highest level. Under the optimal treatment condition, the 4-chlorophenol (4-CP) removal of the membrane filtration combined with peroxymonosulfate (PMS) activation (MFPA) process was up to 98.

A dual-functional hydrogel for efficient water purification: Integrating solar interfacial evaporation with fenton reaction.

Solar interfacial evaporation is a potential technology to produce clean water due to its simplicity and being driven by renewable clean energy, but it still requires further development to break through the bottleneck of removing volatile organic compounds (VOCs), especially in wastewater treatment. Herein, we proposed a dual-functional hydrogel evaporator that coupled solar interfacial evaporation with Fenton reaction to simultaneously remove VOCs and non-volatile pollutants from water with low energy consumption and high efficiency. The evaporator was composed with β-FeOOH and polydopamine (PDA) on an electrospun nanofibrous hydrogel.

Discoidin domain receptor 2 expression increases phagocytotic capacity in sertoli cells of sertoli cell-only syndrome testes.

Discoidin domain receptor 2 (DDR2) belongs to the receptor tyrosine kinase (RTK) family, other RTKs have been reported to regulate phagocytic function of Sertoli cells (SCs), yet little is known about the function of DDR2 in Sertoli cells. In the present study, we aim to explore the function and mechanism of ectopic discoidin domain receptor 2 (DDR2) expression in Sertoli cells of Sertoli cell-only syndrome (SCOS) testes. We found that discoidin domain receptor 2 (DDR2) was absent in Sertoli cells of normal testis but was expressed in Sertoli cells of SCOS testes.

A novel, flexible porous nanofibrous hydrogel interfacial solar evaporator for highly efficient seawater and wastewater purification.

Solar desalination is recognized as one of the eco-friendly and sustainable ways to alleviate the global freshwater crisis but still requires further research, especially in developing high-performance evaporators. Herein, we prepared an efficient carbon nanotubes (CNTs)@polyvinyl alcohol (PVA) nanofibrous hydrogel evaporator by electrospinning and subsequently chemical cross-linking treatment. Due to CNTs with good light absorption capacity, the evaporator exhibited an excellent light absorption capacity (>90%) throughout the full spectrum range (250-2500 nm).

Insights into the impact of polydopamine modification on permeability and anti-fouling performance of forward osmosis membrane.

Forward osmosis (FO) has drawn wide attention as a promising method to address world-wide water crisis due to the advantages of low-energy consumption and easy separation operation. Unfortunately, the trade-off between permeability and selectivity as well as membrane fouling hindered the application of forward osmosis. Surface modification is a feasible method to address these issues.

The Chinese mitten crab genome provides insights into adaptive plasticity and developmental regulation.

The infraorder Brachyura (true or short-tailed crabs) represents a successful group of marine invertebrates yet with limited genomic resources. Here we report a chromosome-anchored reference genome and transcriptomes of the Chinese mitten crab Eriocheir sinensis, a catadromous crab and invasive species with wide environmental tolerance, strong osmoregulatory capacity and high fertility. We show the expansion of specific gene families in the crab, including F-ATPase, which enhances our knowledge on the adaptive plasticity of this successful invasive species.

Large-scale lysine crotonylation analysis reveals its potential role in spermiogenesis in the Chinese mitten crab Eriocheir sinensis.

Lysine crotonylation (Kcr) is a recently-discovered type of post-translational modification. Although Kcr has been reported in many species, little is known about this process in crustaceans. In this study, pan anti-lysine crotonylation antibody enrichment and high-resolution liquid chromatogram-mass spectrometry analysis were employed to characterize Kcr in testis of the Chinese mitten crab Eriocheir sinensis testis.

Efficient Technique for Simultaneous Lead Recovery and PbO₂/Ti Electrode Preparation for Electrocatalytic Degradation of Basic Red.

In order to achieve the effective removal of Pb from low-concentration wastewater as well as the lead recovery for direct reuse simultaneously, a simple electrodeposition method was used in this study. In this process, synthetic lead wastewater with low concentration of 4, 8, 12 and 16 mg/L was treated, more than 67% lead was recovered from wastewater and a PbO₂/Ti electrode was fabricated in a simple reaction tank. The test results of characterizations confirmed that PbO₂ nanoeletrocatalyst was successfully deposited on a Ti substrate.

Identification, functional characterization and the potential role of variable lymphocyte receptor EsVLRA from Eriocheir sinensis in response to secondary challenge after Vibrio parahaemolyticus vaccine.

Variable lymphocyte receptors (VLRs) play an important role via their antigen-special reorganization in jawless vertebrates (agnathans) adaptive immune response. In the present study, the open reading frame (ORF) of Eriocheir sinensis VLRA (designated as EsVLRA) was identified. EsVLRA comprised a 799-amino-acid polypeptide with one LRR_NT domain, thirteen LRR domains and one LRR_CT domain, which showed a high domain consistency of the VLR genes in lamprey (Petromyzon marinus).

The Interannual Evolution of PAHs in Columnar Sediments in Offshore Area of Changxing Island Industrial Zone, China.

Changxing Island, located in the northwest of Dalian City in Liaoning, China, is a beautiful island on the West side of the Liaodong Peninsula. Since 1980, along with the development of the economic benefits and the environmental evolution of the Changxing Island marine belt, its ecological environment has changed to a certain extent. In this paper, the interannual evolution and organic pollution of polycyclic aromatic hydrocarbons (PAHs) in borehole core samples were studied, based on the survey data of coastal substrates and sedimentation chemistry of two columnar stations (C4 and C6) in Changxing Island, China, in 2017.
