In this study, Chinese cabbage ( L. ssp. ) roots were solvent fractioned, and their antioxidant and anti-inflammatory effects were investigated. The antioxidant capacity (DPPH and ABTS radicals, oxygen radical absorbance capacity, and cupric reducing antioxidant capacity) was the highest in the ethyl acetate fraction (CREE) at 26.74, 69.81, 253.23, and 54.77 mg TEAC/g, respectively. The inflammatory responses were evaluated in RAW 264.7 cells stimulated with lipopolysaccharide (1 µg/mL). CREE decreased nitric oxide and prostaglandin E2 by 53.37% and 16.30%, respectively. Pro-inflammatory cytokines such as tumor necrosis factor-α, interleukin-1β, and interleukin-6 were inhibited by 36.85%, 62.99%, and 54.78%, respectively. Furthermore, inducible nitric oxide synthase, cyclooxygenase-2, and interleukin-6 genes were inhibited by 43.38%, 24.23%, and 80.85%, respectively. The results suggest that CREE is responsible for its antioxidant and anti-inflammatory effects.

Lateral flow immunoassay (LFIA) has the advantages of simplicity and rapidness, and is widely used for the rapid detection of pesticides and other analytes. However, small molecule compounds such as pesticides are often analyzed using competitive LFIA (CLFIA), whose sensitivity often does not meet the actual needs. In this study, a noncompetitive LFIA (NLFIA) for deltamethrin (DM) with high sensitivity was developed by using anti-immunocomplex peptides (AIcPs).

To investigate the remediation effects of various modified biochar materials derived from different impregnation agents on Cd- and Pb-contaminated calcareous soil, nitrogen (N-), phosphorus (P-), sulfur (S-), and iron (Fe-) modified biochar materials (NBC, PBC, SBC, FBC) were fabricated through the impregnation-pyrolysis method and employed to immobilize Pb and Cd in the calcareous soil. The characterization results showed that NBC exhibited an uneven pore size distribution and increased aromaticity, while PBC and SBC had increased pH and ash content. Pot experiments demonstrated significantly different effects of various modified biochar materials on soil immobilization and plant uptake of Cd and Pb.

Atmospheric fine particulate matter (PM) is the main contributor to Pb accumulation in edible Chinese cabbage leaves in North China. PM-Pb primarily enters leaves via stomatal foliar uptake. However, how PM-Pb is transported and stored within the leaf cells of Chinese cabbage remains unclear.
