In this study, mung bean-based nanoporous activated carbons with different pore properties were prepared by varying the mass ratio of activating agent (KOH) and activation temperature. The low-temperature nitrogen adsorption analysis was used to characterize the effect of the KOH ratios and the activation temperatures on the textural properties and surface heterogeneity. The prepared ACs were further used to measure the adsorption capacity of CO2, CH4, and N2. We found that the adsorption amounts were highly dependent on the ultra-micropore volume (VD<0.8nm) rather than the surface area. Their adsorption characteristics were well explained by the polarizability and the adsorption energy distribution. The experimental adsorption isotherm data were well fitted to the Sips equation. The ideal adsorbed solution theory (IAST) was further applied to predict the adsorption selectivity of binary mixtures CO2/N2, CO2/CH4, and CH4/N2 at 25 °C. [ABSTRACT FROM AUTHOR]

In the present study, we aimed to examine the inhibition of genomic DNA from Lactiplantibacillus plantarum (LpDNA) on Porphyromonas gingivalis lipopolysaccharide (PgLPS)-induced inflammatory responses in RAW264.7 cells. Pretreatment with LpDNA for 15 h significantly inhibited PgLPS-induced mRNA expression and protein secretion of interleukin (IL)-1β, IL-6, and monocyte chemoattractant protein-1. LpDNA pretreatment also reduced the mRNA expression of Toll-like receptor (TLR)2 and TLR4. Furthermore, LpDNA inhibited the phosphorylation of mitogen-activated protein kinases (MAPKs) and the activation of nuclear factor-κB (NF-κB) induced by PgLPS. Taken together, these findings demonstrate that LpDNA attenuates PgLPS-induced inflammatory responses by regulating MAPKs and NF-κB signaling pathways through the suppression of TLR2 and TLR4 expression., Competing Interests: The authors declare no potential conflicts of interest., (© Korean Society for Food Science of Animal Resources.)
