N-acyl-homoserine-lactones as a critical factor for biofilm formation during the initial adhesion stage in drinking water distribution systems.

The N-acyl-homoserine-lactone (AHLs)-mediated quorum sensing (QS) system is crucial for the coordination of microbial behaviors within communities. However, the levels of AHLs in biofilms in drinking water distribution systems (DWDSs) and their impact on biofilm formation remain poorly understood. Herein, we simulated DWDSs via biofilm reactors to explore the presence and influence of AHLs during the initial stages of biofilm formation on pipe walls.

Triglyceride glucose index: a significant prognostic marker of heart failure in patients with chronic kidney disease.

Background: Triglycerides and glucose (TyG) index, a relatively convenient method for assessing insulin resistance, has been confirmed as an independent predictor both for chronic kidney disease (CKD) and cardiovascular disease (CVD) in previous studies. However, a few studies focus on the prognostic value of TyG index for CVD in patients diagnosed with CKD, especially in advanced CKD patients. In this study, we aim to investigate the prognostic value of TyG index for heart failure (HF) in patients with non-dialysis CKD stage 3-5.

Methods: This prospective, multicenter study was registered on the Chinese Clinical Trial Registry (ChiCTR2400085035). From October 2018 to February 2024, a total of 303 breast cancer patients with biopsy-proven positive LN were enrolled.

Enhancing tumor immunotherapy via photodynamic therapy with a cascade reaction of reactive oxygen species and sustaining nutrient supply.

Photo-immunotherapy is a promising strategy for the treatment of malignancies; however, its efficacy is often limited by the low tumor immunogenicity and immunosuppressive tumor microenvironment (TME). TME is typically deficient in L-arginine (L-Arg), which negatively impacts T cell survival and function. To address this issue, we developed a novel drug delivery system based on the multi-vesicular liposomes (MVLs) loaded with photosensitizer indocyanine green (ICG) and L-Arg (R), named R-ICG@MVLs.

Jiawei Taohe Chengqi Decoction attenuates CCl induced hepatic fibrosis by inhibiting HSCs activation via TGF-β1/CUGBP1 and IFN-γ/Smad7 pathway.

Background: Hepatic fibrosis (HF) is an essential stage in the progression of different chronic liver conditions to cirrhosis and even hepatocellular carcinoma. The activation of hepatic stellate cells (HSCs) plays a crucial role in the progression of HF. IFN- γ/Smad7 pathway can inhibit HSCs activation, while TGF-β1/CUGBP1 pathway can inhibit IFN-γ/Smad7 pathway transduction and promote HSCs activation.

Remodeling the hepatic immune microenvironment and demolishing T cell traps to enhance immunotherapy efficacy in liver metastasis.

Immune checkpoint inhibitors (ICIs) exhibit compromised therapeutic efficacy in many patients with advanced cancers, particularly those with liver metastases. Much of this incapability can be ascribed as an irresponsiveness resulting from the "cold" hepatic tumor microenvironment that acts as T cell "traps" for which there currently lack countermeasures. We report a novel nanomedicine that converts the hepatic immune microenvironment to a "hot" phenotype by targeting hepatic macrophage-centric T cell elimination.
