Background: The emerging incidence of pathogenic liver conditions is turning into a major concern for global health. Induction of pyroptosis in hepatocytes instigates cellular disintegration, which in turn liberates substantial quantities of pro-inflammatory intracellular substances, thereby accelerating the advancement of liver fibrosis. Consequently, directing therapeutic efforts towards inhibiting pyroptosis could potentially serve as an innovative approach in managing inflammation related chronic hepatic disorders.

National Engineering Research Center for Biomaterials, Sichuan University, Chengdu 610064, China; Research Unit. of Minimally Invasive Treatment of Structural Heart-Disease, Chinese Academy of Medical Sciences (2021RU013), Chengdu 610064, China.

Ensuring excellent anticoagulant, anti-inflammatory, and endothelialization properties in vascular stents through coating construction is crucial for their satisfactory performance post-implantation. In this study, we propose a cell-membrane mimetic multifunctional hyaluronic acid (HA)-based coating by combining the aminolyzed methacryloyloxyethyl phosphorylcholine (MPC) copolymer with oxidized hyaluronic acid (Ox-HA) through Schiff base reaction. Compared with traditional anti-fouling design, the composite coating present a stage-specific ability, which can resist the adhesion of blood components, while mediating vascular cell fate with the incorporation of HA.

Article Synopsis
  • The invention of lasers and inorganic second-order nonlinear optical (NLO) crystals has revolutionized technology by enabling unique frequency conversions, essential for various applications including information transmission and industrial uses.
  • As the demand for shorter wavelengths and higher precision lasers increases, there is a pressing need for high-performance ultraviolet NLO materials, especially those with wavelengths less than 300 nm.
  • Current methods of discovering these materials are often inefficient and based on trial-and-error; therefore, a three-step strategy is proposed for a more rational design, focusing on screening new functional groups, regulating crystal structures, and optimizing synthesis to meet stringent performance criteria.

Lactate exhibits various biological functions, including the mediation of histone and non-histone lactylation to regulate gene transcription, influencing the activity of T lymphocytes, NK cells, and macrophages in immune suppression, activating G protein-coupled receptor 81 for signal transduction, and serving as an energy substrate. The mA modification represents the most prevalent post-transcriptional epigenetic alteration. It is regulated by mA-related regulatory enzymes (including methyltransferases, demethylases, and recognition proteins) that control the transcription, splicing, stability, and translation of downstream target RNAs.
