Inhibition effect of glycyrrhizin in lipopolysaccharide-induced high-mobility group box 1 releasing and expression from RAW264.7 cells.

Introduction: High-mobility group box 1 (HMGB1) is a therapeutic target for sepsis. Glycyrrhizin (GL) is the aglycone of glycyrrhizin derived from licorice. We clarified the anti-inflammatory effects of GL.

Direct current conductivity of carbon nanofiber-based conductive polymer composites: effects of temperature and electric field.

Polymer composites based on high density polyethylene (HDPE) and carbon nanofiber (CNF) were fabricated by melt compounding. The dependences of electrical conductivity of HDPE-CNF composites on filler concentration, temperature, and applied electric field were investigated. The results showed that the conductivity of the HDPE-CNF composites follows the scaling law of percolation theory.
