Abstract Hepatitis has imposed a substantial burden on human health. Tumor necrosis factor-α (TNF-α) drives the inflammatory response by triggering downstream signaling, particularly the nuclear factor kappa B (NF-κB) pathway. Suppressing NF-κB activation represents a promising therapeutic strategy. PEGNB, a polymeric hydrogel, exhibits significant potential due to its superior cytocompatibility. We developed a controlled-delivery microgel platform by encapsulating Schisandra lignans (SLs) and mesenchymal stromal cells (MSCs) in polyethylene glycol-norbornene (PEGNB) microgels. To mimic an inflammatory hepatic microenvironment in vitro, Lipopolysaccharide (LPS)-induced HepG2 cells were encapsulated in bulk PEGNB hydrogel. The microgel–cell system enabled localized co-delivery of SLs… More >

Abstract Health remains a persistent focus of research. Currently, many commonly used synthetic dyes are toxic to some extent. Tartrazine is a common synthetic dye used in the food, pharmaceutical, printing, and dyeing industries. Long-term exposure to this substance or its ingestion may pose significant health risks. In addition, oxidizing agents used in water treatment may threaten environmental and human health if they are not properly controlled. Hydrogen peroxide (H₂O₂) is one of the most widely used oxidants and therefore requires effective monitoring. Against this background, this study contributes to the efficient detection of environmentally harmful substances… More >

Abstract Dental caries (or tooth decays) is a common oral disease in early childhood and adults of all ages, which is caused by long-term synergies of acid-producing bacteria and fermentable carbohydrates in the oral environment. The use of existing dental restorative materials (including silver amalgams, light-cured resins, and dental restorative composites) and dental restorative composites (including glass ionomers cement, despite being sealants, releasing fluoride and promoting remineralization) is commercially restricted due to their weak mechanical properties, poor abrasion resistance, low elastic modulus, improper shrinkage, less polishability, brittleness, poor wear resistance tensile strength, aesthetic etc. Therefore, the… More >

Abstract The increasing prevalence of plastic pollution demands strategies for sustainable biodegradable plastic production. Marine bacteria can be found on all continents able to survive in a variety of salinity levels and may be used to biosynthesis polyhydroxyalkanoates (PHAs), which can serve as a bioplastic substitute for conventional petroleum-based plastics. This paper presents a literature review and case study examining marine PHAs-producing microorganisms in the context of a circular bioeconomy and waste management. More specifically, it examines the marine PHA-producing bacteria's ability to utilise varying and renewable carbon substrates for PHA biosynthesis. From prior research studies, More >

Abstract Underwater adhesives serve as essential functional materials with extensive applications in underwater robotic operations, submarine pipeline installation and maintenance, maritime defense projects, and marine engineering infrastructure. However, the construction of robust and reliable underwater bonding interfaces is severely constrained by substrate surface hydration layers and limited interfacial interaction strength, which has become a core bottleneck restricting the development of high-performance underwater adhesives. Herein, we use in situ polymerization and particle reinforcement to enhance adhesion strength: An underwater adhesive is prepared by reacting bis(3-aminopropyl)-terminated polydimethylsiloxane with hexamethylene diisocyanate in the presence of Ca(OH)₂, which acts as a precursor… More >
