Abstract:
Decabromodiphenyl ether (BDE-209) and Sodium nitrite (SN) coexist in the processing meat and fish foods, but there is no research considering them together. The present study aimed to investigate the binary mixture's toxicity of BDE-209 and SN and explore the protective effect of hesperidin (Hsp) on the combined toxicity. Results showed that compared with the impact of BDE-209 or SN alone, the binary mixture had a synergistic toxic effect on impairing the viability of HepG2 cells, accompanied by oxidative stress, Ca2+ accumulation, mitochondrial dysfunction. The increase of γ-H2AX fluorescent foci and micronuclei number also indicated its genotoxicity. Pretreatment of Hsp could significantly alleviate the above damage caused by the binary combination. These findings revealed the toxicological interaction of BDE-209 and SN and highlighted that food containing abundant natural flavonoids, as hesperidin, could reduce this toxicological risk.

Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....

The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by...
