The pathogenesis of nasal polyps is not completely understood. Oxidative damage contributes to polyp formation in the nasal mucosa. The paraoxonase 1 (PON1) enzyme is an important liver enzyme with high antioxidant activity. In this study, we investigated the correlation between Q192R genotypic polymorphism of the PON1 enzyme and nasal-polyp disease. The study examined 62 nasal-polyp patients and 88 controls. PON1 Q192R polymorphism was determined using polymerase chain reaction-restriction fragment length polymorphism. The genotype distribution of the PON1 gene was significantly different between nasal-polyp patients (QQ = 69.35%, QR = 25.81%, RR = 4.83%) and healthy controls (QQ = 52.27%, QR = 44.31%, RR = 3.40%). Our results suggest that the PON1 QQ genotype (odds ratio [OR] = 2.066, P = .036) is associated with a higher risk of developing the nasal-polyp disease while QR genotype (OR = 0.437, P = .021) showed a lower risk.

Introduction: The present study concerns a connection of the Q192RPON1 polymorphism with atherosclerosis requiring percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in the Polish population.

Methods: A total of 282 individuals who underwent coronary angiography took part in this study. The polymorphism was determined with the PCR-RFLP method.

Numerous studies have tried to evaluate the potential role of thrombophilia-related genes in retinal vein occlusion (RVO); however, there is limited research on genes related to different pathophysiological mechanisms involved in RVO. In view of the strong contribution of oxidative stress and inflammation to the pathogenesis of RVO, the purpose of the present study was to investigate the association of inflammation- and oxidative-stress-related polymorphisms from three different genes [] and the risk of RVO in a Greek population. Participants in this case-control study were 50 RVO patients (RVO group) and 50 healthy volunteers (control group).

Scope: The present study aims to assess the interaction of dietary patterns (DPs) and paraoxonase1 (PON1) rs662 polymorphism on coronary artery disease (CAD) severity and its risk factors.

Methods And Results: This cross-sectional study is conducted on 425 patients undergoing angiography. The PON1 genotypes are detected by the polymerase chain reaction-restriction fragment length polymorphism (RFLP-PCR) technique.
