Coelonin protects against PM -induced macrophage damage via suppressing TLR4/NF-κB/COX-2 signaling pathway and NLRP3 inflammasome activation in vitro.

One of the important monitoring indicators of the air pollution is atmospheric fine particulate matter (PM ), which can induce lung inflammation after inhalation. Coelonin can alleviate PM -induced macrophage damage through anti-inflammation. However, its molecular mechanism remains unclear.

Polysaccharides from Diels et Gilg: optimum extraction, monosaccharide compositions, and antioxidant activity.

The optimization of extraction of Diels et Gilg polysaccharides (THP) using ultrasonic with enzyme method and its monosaccharide compositions and antioxidant activity were investigated in this work. Single-factor experiments and response surface methodology (RSM) were performed to optimize conditions for extraction, and the independent variables were () dosage of cellulase, () extraction time, () ultrasonic power, and () ratio of water to the material. The extraction rate of THP was increased effectively under the optimum conditions, and the maximum (4.
