Due to the poor regeneration ability of cartilage tissue, the design and fabrication of permanent hydrogel cartilage scaffolds with mechanical properties matching is still an urgent challenge. In this study, we propose an "inner swelling-outer restraint" strategy to construct Janus hydrogel for pressure-bearing cartilage replacement, which is inspired by the "Lamina-splendens" structure of cartilage. As a proof of concept, the poly(vinyl alcohol)/carboxymethyl cellulose sodium (PVA/CMCNa) layer is designed to capture more fluid by introducing negatively charged aggregates, while the macromolecular conformation of the PVA/MoS layer can be densified through wet annealing, thereby increasing the liquid permeation resistance of the PVA/CMCNa layer.

This paper aimed to explore the effects of Duzhong Decoction(DZD)-containing serum on the proliferation and osteoblast differentiation of MC3T3-E1 cells through L-type voltage-gated calcium channels(L-VGCCs). L-VGCCs inhibitors, nifedipine and verapamil, were used to block L-VGCCs in osteoblasts. MC3T3-E1 cells were divided into a control group, a low-dose DZD-containing serum(L-DZD) group, a medium-dose DZD-containing serum(M-DZD) group, a high-dose DZD-containing serum(H-DZD) group, a nifedipine group, a H-DZD + nifedipine group, verapamil group, and a H-DZD + verapamil group.

Background And Aims: Radiofrequency ablation (RFA) is the first-line treatment for early-stage hepatocellular carcinoma (HCC). However, recurrence after curative RFA remains a significant challenge for HCC patients. Although RFA induces an immune response, the anti-tumor effect is often limited by the immunosuppressive tumor microenvironment.

As part of sewage treatment, coagulation could remove phosphorus from the effluent of the Anaerobic-Anoxic-Oxic-Anoxic (AOA) biological process. The importance in investigating the influence of coagulation on Anaerobic-Anoxic-Oxic-Anoxic Membrane Bioreactor (AOA-MBR) should be emphasized. In this study, systematic optimization of coagulation parameters for greater pollutant removal was conducted in terms of coagulant dosage, coagulation residence time and stirring hydraulic conditions.

Introduction: The seeds of represent a unique category of herbaceous seeds that arise from triploid apomixis. They necessitate an exceptionally protracted maturation phase of 8 months, followed by a dormancy period of 4 months, before they can germinate and give rise to fully formed new plants. Currently, the connection between endophytic microbial communities in seeds and the host plant's development is largely unexplored.

To investigate the microscopic mechanism of aging-induced "dewetting" at the matrix/filler interface in Nitrate Ester Plasticized Polyether (NEPE) propellant, this study decoupled the aging process into two factors: crosslinking density evolution and nitrate ester decomposition. Molecular dynamics (MD) simulations were employed to construct all-component matrix models and matrix/filler interface models with varying aging extents. Key parameters including crosslinking density, mechanical properties, free volume fraction, diffusion coefficients of the matrix, as well as interfacial binding energy and radial distribution function (RDF) were calculated to analyze the effects of both aging factors on "debonding".

Members of the heat shock protein 90 family (HSP90s) are evolutionarily conserved and play crucial roles in protein transport, immune regulation and antigen presentation. In this study, five hsp90s were identified from the genome of large yellow croaker (Larimichthys crocea) and analyzed using bioinformatics. All five identified hsp90s encode proteins with HATPase_c and HSP90 domains, and are mainly localized in the cytoplasm, mitochondria and endoplasmic reticulum.

Pcc is one of the key pathogenic factors responsible for destructive soft rot in konjac. To date, the assembly and functional adaptation of the plant endophytic microbiome under Pcc stress remain poorly understood. Here, we found that Pcc stress leads to rapid reorganization of the endogenous microbiome in multiple organs of both susceptible and resistant konjac plants.

Antimicrobial peptides (AMPs) are small molecular peptides that widely exist in organisms to resist external microbial invasion and play a crucial role in the host's immune defense system. Owing to their functions of efficient broad-spectrum killing of pathogenic microorganisms, immune enhancement, and intestinal health improvement, they have emerged as a focal point in research on the immune defense of aquatic animals in recent years. In this study, a total of 105 putative AMP-derived genes from the genome were screened, and seven candidate AMPs were finally identified by analyzing the differential expression results of the hepatopancreas and the white body transcriptomes combined with machine learning algorithms.

3D cartilage tissue engineering scaffolds with stable structures are crucial for promoting cartilage tissue growth and repair. However, limited research attention is given to the effects of 3D cells-membrane-cells sandwich-like living complexes with enhanced structural stability for cartilage repair. In this study, silk fibroin/graphene oxide@kartogenin (SF/GO@KGN) fibrous membranes with improved structural stability are developed through the regulation of the crystallinity, and living complexes are constructed for cartilage repair using rat bone marrow stromal cells (rBMSCs) and the SF/GO@KGN fibrous membranes.

Bacterial resistance and biofilm formation around diabetic wounds are major challenges that make the wounds difficult to heal. It is crucial for diabetic wound healing to improve the microenvironment around the wounds. In this study, a novel strategy for diabetic wound healing is developed by combining the peroxidase (POD)-like enzyme activity and photothermal therapy (PTT) to protect against bacterial infections around the wounds.

  • Clonorchis sinensis infection significantly worsens overall survival rates in patients with intrahepatic cholangiocarcinoma (ICC) compared to those without the infection.
  • Researchers used RNA sequencing and animal models to investigate how C. sinensis infection facilitates the progression of ICC.
  • The study found that C. sinensis infection leads to increased expression of fatty acid synthase (FASN), which promotes fatty acid synthesis and tumor growth, suggesting a potential new target for treatment in ICC patients infected with C. sinensis.

Glioma is recognized as one of the most lethal and aggressive brain tumors. Although the standard-of-care treatment for glioblastoma (GBM) involves maximal surgical resection and temozolomide (TMZ) chemotherapy, the discovery of novel anti-tumor agents from nature sources is an effective strategy for glioma treatment. In this study, we conducted a screening process to identify the bisindole alkaloid melodinine J (MDJ) from Melodinus tenuicaudatus.

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.
