All participants completed short-term HRV measurements, and were collected blood specimens to measure PON1 activities and the genotype of the PON1 Q192R polymorphism.\nRESULTS: In a multivariate regression model, this study observed a positive relationship between nano-Ag exposure and HRV time-domain (RMSSD) and frequency-domain (HF). After adjusting for confounders, the results showed positive associations between RR homozygosity, PON1 paraoxonase/arylesterase activities with HRV, and was particularly noteworthy in RMSSD and HF.\nCONCLUSIONS: This study shows a significant increment of RMSSD and HF among workers who handled Nano-Ag materials. These results imply that Nano-Ag and PON1 Q192R genotype can trigger ANS reflexes and alter cardiac frequency and function.","tracks":[]}
