This study investigated the therapeutic effects of a water-soluble biphenyl compound, WLP-S-14, in acute-on-chronic liver failure (ACLF). Wistar rats were injected intraperitoneally with porcine serum twice a week for 8 weeks prior to administration of 600 mg/kg D-galactosamine and 50 μg/kg lipopolysaccharide to induce ACLF. Study groups were treated intravenously with saline or with 100 or 200 mg/kg WLP-S-14. WLP-S-14 ameliorated ACLF with significant reductions in the mortality rate and transaminase levels, indicating improved liver function. The mechanism underlying these effects may involve decreased levels of tumor necrosis factor-α and interleukin-6, with associated inhibition of apoptotic pathways. [ABSTRACT FROM AUTHOR]

The visualization of self‐assembled structure and dynamics at the molecular level has become a powerful method to understand structure–function relationships of self‐assembly. Herein, we in situ real‐time imaged the dynamic process of benzyl‐naphthalimide dyes at the nanoscale and inspected their internal structure with minimum 2.8 nm localization accuracy through single‐molecule localization microscopy (SMLM) imaging. We monitored the growth process of three different assemblies in situ, which possessed highly heterogeneous dynamics with different shapes and growth rates. Furthermore, diverse growth rates were also found at different sites in the same assembly. These results highlight the application of super‐resolution microscopy techniques for real‐time visualization of internal assembled structure and dynamics in situ. [ABSTRACT FROM AUTHOR]
