Comparisons of efficacy and safety of 400 or 800 ml bacterial count fecal microbiota transplantation in the treatment of recurrent hepatic encephalopathy: a multicenter prospective randomized controlled trial in China.

Background: Hepatic encephalopathy (HE) represents a critical complications of end-stage liver disease, serving as an independent predictor of mortality among patients with cirrhosis. Despite effective treatment with rifaximin, some patients with HE still progress to recurrent episodes, posing a significant therapeutic challenge. Recurrent HE is defined as experiencing two or more episodes within a 6-month period.

The Masculinizing gene is a candidate male pathway developmental factor in the mud crab Scylla paramamosain.

The Masculinizer (Masc) gene plays a crucial role in masculinization during insect embryonic gonadal development. Nevertheless, the Masc expression pattern and function in crabs remain largely unknown. In the present study, we screened and validated the Masc gene from transcriptome data of mud crab S.

Phase-Separated Nano-Antibiotics Enhanced Survival in Multidrug-Resistant Escherichia coli Sepsis by Precise Periplasmic EcDsbA Targeting.

Disulfide bond (Dsb) proteins, especially DsbA, represent a promising but as-yet-unrealized target in combating multidrug-resistant (MDR) bacteria because their precise subcellular targeting through multibarrier remains a significant challenge. Here, a novel heterogenization-phase-separated nano-antibiotics (NCefoTs) is proposed, through the co-assembly of enzyme-inhibiting lipopeptides (ELp component), membrane-recognizing and disrupting lipopeptides (MLp component), and cefoperazone. The self-sorting components of MLp "concentrated island-liked clusters" on the surface of NCefoTs promote the efficient penetration of NCefoTs through the outer membrane.

The immune function of TLR4-1 gene in Octopus sinensis revealed by RNAi and RNA-seq.

Toll-like receptors (TLRs) are a class of conserved pattern recognition receptors (PRRs) that are crucial for initiating the innate immune response and aiding in the clearance of pathogenic organisms. Many studies have identified TLR4 as a distinctive member of the TLR family, capable of activating both the Myeloid differentiation factor 88-dependent signaling pathway (MyD88-dependent) and the TIR-domain-containing adaptor inducing IFN-β dependent signaling pathway (TRIF-dependent). Nevertheless, the role of TLR4 in Cephalopoda is still largely unexplored.

Induction of Pluripotent Stem Cells from Muscle Cells of Large Yellow Croaker (Larimichthys Crocea) Via Electrotransfection.

Induced pluripotent stem cells (iPSCs) are a new type of pluripotent cells reprogrammed from somatic cells back into an embryonic-like pluripotent state of stem cells to study development, disease and potential gene therapies. The induction and regulation mechanisms of iPSCs in fish are still unclear. By using the transfection technique, we investigated the crucial function of the OSKMNL factor co-expression for somatic reprogramming in the muscle cell line of large yellow croaker (Larimichthys crocea) (LYCMs) and successfully established a stable iPSCs line (Lc-OSNL-iPSCs).

miR-34 negatively regulates the expression of Dmrt and related genes in the testis of mud crab Scylla paramamosain.

A member of the immunoglobulin superfamily lrig-1 might be involved in the immune priming of Scylla paramamosain in response to the infection and re-infection by Vibrio parahaemolyticus.

A member of the immunoglobulin superfamily designated leucine-rich repeats and immunoglobulin-like domains protein-1 (lrig-1) encoding a protein with 1109 amino acids with a characteristic IGc2 domain was identified from the transcriptome data of mud crab Scylla paramamosain.

Landscapes of gut microbiome and bile acid signatures and their interaction in HBV-associated acute-on-chronic liver failure.

Introduction: Submassive hepatic necrosis (SMHN, defined as necrosis of 15-90% of the entire liver on explant) is a likely characteristic pathological feature of ACLF in patients with hepatitis B cirrhosis. We aimed to comprehensively explore microbiome and bile acids patterns across enterhepatic circulation and build well-performing machine learning models to predict SMHN status.

Methods: Based on the presence or absence of SMHN, 17 patients with HBV-related end-stage liver disease who received liver transplantation were eligible for inclusion.

Lymphocyte Membrane- and 12p1-Dual-Functionalized Nanoparticles for Free HIV-1 Trapping and Precise siRNA Delivery into HIV-1-Infected Cells.

Despite the success of small interfering RNA (siRNA) in clinical settings and its potential value in human immunodeficiency virus (HIV) therapy, the rapid clearance and absence of precise delivery to target cells still hinder the therapeutic effect of siRNA. Herein, a new system, which can escape immune recognition, has HIV-1 neutralizing capacity, and the ability to deliver siRNA specifically into HIV-1-infected cells, is constructed by functionalizing siRNA delivery lipid nanoparticles with the lymphocyte membrane and 12p1. The constructed system is shown to escape uptake by the mononuclear phagocyte system.

A Membrane Curvature Modulated Lipopeptide to Broadly Combat Multidrug-Resistant Bacterial Pneumonia with Low Resistance Risk.

The extensive spread of multidrug resistance to Gram-negative bacteria has become a huge threat to human health, where peptide-based antibacterial agents have emerged as a powerful star weapon. Here we report a lipopeptide () constructed nanomicelle with a different antibacterial mechanism of membrane curvature modulation, which induced dynamic membrane fission resulting in acceleration and enhancement of antibacterial activity to clinically isolated ESKAPE strains, including multidrug-resistant (MDR) pathogens. The minimum inhibitory concentration was reduced to 2-10 μM, and the minimum duration for killing was shortened to less than an hour by .

The Japanese eel (Anguilla japonica) experiences dramatic internal and external environmental changes during its transoceanic reproductive migrations. Here, we assess immune function changes in the primary and secondary immune organs (head kidney and spleen) of A. japonica during artificial ovarian maturation at the previtellogenic (PV), midvitellogenic (MV), and ovulating (OV) stages by transcriptome analyses.

Integration of RNAi and RNA-seq uncovers the regulation mechanism of DDX20 on vitellogenin expression in Scylla paramamosain.

Vitellogenesis in crustaceans is controlled by several steroid hormones. In humans, the expression of SF-1, a gene that regulates gonadal development and the synthesis of steroid hormones, is affected by DDX20. However, how the homologous gene FTZ-F1 is regulated by DDX20 and its association with vitellogenesis remains unknown in the mud crab Scylla paramamosain.
