RESUMO
PURPOSE: The study aimed to examine if the polymorphism of the endothelial nitric oxide synthase (eNOS) gene variable number of tandem repeats (VNTR) and the serum NO levels are associated with CAD. MATERIALS/METHODS: Case-control study, 70 CAD and 30 control subjects were enrolled. The eNOS gene polymorphism was measured by polymerase chain reaction-agarose gel electrophoresis and the serum NO was assessed by using an ELISA plate and reader covering 540 nm. RESULTS: Uncovering the area under curve (AUC) for serum NO, which was (0.6821), indicating that NO seemed to be a critical prognostic biomarker of CAD; also, glucose, serum creatinine and total bilirubin proved to be significant predictors of CAD with AUC (0.6793, 0.6717 and 0.6662) respectively. Furthermore, higher serum NO levels were associated with the eNOS (ab) genotype. Revealing the intron (a) allele was protective against CAD. Moreover, diminished levels of serum NO in CAD groups compared to controls (P < 0.05). Additionally, Multiple logistic regression analysis shows a significantly high Odds ratio associated with CAD in the Duhok population. CONCLUSIONS: The eNOS (ab) variant seems to be a protective CAD factor for patients. Low serum NO levels are another risk factor for the advancement of CAD, suggesting their involvement in atherosclerosis. The (a) allele's protective effect is mediated through changes in eNOS promoter activity and higher NO levels.

OBJECTIVE: Coronary artery disease (CAD) is a complex disorder influenced by genetic and environmental factors. This case-control study investigated the association between Sirtuin SIRT3 gene polymorphisms, serum malondialdehyde (MDA) levels, and CAD susceptibility. METHODS: Blood samples were collected from 70 CAD cases and 30 controls at the Cardiac Center, Azadi Teaching Hospital, Duhok, Iraq. Genomic DNA was extracted, and PCR-based allele genotyping determined SIRT3 rs11246029 T/C polymorphisms. Serum MDA levels were measured using ELISA. Statistical analysis included t-tests, Mann-Whitney tests, and Spearman correlations. Odds ratios (OR) with 95% confidence intervals (CI) assessed genotypes/alleles and CAD associations. The accuracy of serum MDA in predicting the severity of CAD was evaluated using receiver operating characteristic (ROC) curve analysis. RESULTS: There were no significant variations in serum MDA levels between controls and CAD patients in the study. The diagnostic accuracy of serum MDA for CAD severity prediction was modest (Area Under Curve (AUC) = 0.56). Correlations revealed associations between MDA and total bilirubin (negative) and Troponin (positive). CRP correlated positively with LDH, glucose, cholesterol, LDL, CKmB, and Troponin. CKmB and Troponin are positively associated with clinical characteristics. Genotype analysis identified a significantly higher CAD risk with the CC genotype compared to controls. CONCLUSION: These findings shed light on the potential role of SIRT3 gene polymorphisms and serum MDA levels in CAD susceptibility. Further research is needed to understand underlying mechanisms and therapeutic implications based on these markers. TRIAL REGISTRATION: 15092021-9-12. Registered 15 September 2021.

BACKGROUND: The effects of pomegranate juice (PJ) and its components on uterine smooth muscle are unknown. Hence, this study unequivocally demonstrates that pomegranate juice (PJ) significantly impacts myometrial function, providing crucial insights into its relaxant properties and their potential therapeutic applications for uterine-related disorders. RESEARCH DESIGN AND METHODS: Rat uterine smooth muscle horn strips were suspended in Krebs solution organ baths. Contractions were measured isometrically using a transducer (AD instrument Australia). The effects of PJ were evaluated on contractile activity elicited by potassium chloride (KCl 60 Mm) depolarization. Inhibitors of nitric oxide (L-NAME 3 X 10-4), guanylate cyclase (methylene blue 1 X 10-5), and Prostaglandin I2 (indomethacin 3 X 10-5), as well as Potassium Channels blockers, were determined. RESULTS: The juice at concentrations from 1.5-5 mg/ml significantly decreased the rat uterine horn contraction induced by KCl. The NO, cGMP, and PGI2 inhibitors did not block the relaxation response. Furthermore, the PGI2 inhibitor significantly enhanced the relaxation effects; K+ channel blockers had no inhibitory effects on the relaxation responses. Contrarily, GLIB improved considerably relaxation. CONCLUSION: Research suggests pomegranate juice's active ingredient may reduce uterine contractions and treat uterotonic disorders, potentially preventing preterm birth and dysmenorrhea. Further research is needed to determine its mechanism of action. TRIAL REGISTRATION: Code: AEC-013.

BACKGROUND: This study aimed to identify the prevalence and factors associated with abnormal liver enzyme profiles in individuals with type 2 diabetes (T2D) in Zakho, to assess the association between demographic characteristics, clinical parameters, kidney function tests, lipid profiles, glucose levels, and T2D, and to identify resident risk factors. RESEARCH DESIGN AND METHODS: A cross-sectional analysis of T2D patients admitted to Zakho General Hospital was conducted utilizing hospital records. The primary endpoint of interest was attaining HbA1C levels ≥ 6.5%. Analytical methodologies encompassed linear and multivariate logistic regression analyses, with due consideration of the association between diverse parameters and glycemic alterations. Further, the predictive value of biomarkers was evaluated through Receiver Operating Characteristic (ROC) curves and Area Under the Curve (AUC) analyses, complemented by Spearman correlation analysis to explore relationships among laboratory parameters. RESULTS: The study found that 89.4% of participants had HbA1C levels above 6.5%, with a preference for T2D among older individuals (mean age: 52.93-49.89 respectively) and females. Age, glucose levels, and liver enzymes positively correlated with HbA1C. CONCLUSIONS: The study emphasizes the diagnostic importance of liver enzymes in individuals with type 2 diabetes, suggesting that these biomarkers could be valuable indicators of disease severity and progression.

BACKGROUND: Unraveling myeloperoxidase's (MPO) correlation with coronary artery disease (CAD) and genetic variations, this study seeks to enhance diagnostic precision and therapeutic strategies. RESULTS: CAD patients were found to be older and more male than controls. Several clinical parameters, including glucose, total bilirubin, alkaline phosphatase, creatinine, and troponin levels, showed significant variations. Moreover, CAD patients had lower red cell distribution width (RDW%) and mean platelet volume (MPV) than controls. Serum MPO levels did not differ significantly between CAD patients and controls, and no correlation was found with other clinical parameters except for glucose, creatinine, and total bilirubin. CONCLUSIONS: The data suggest that serum MPO levels are not substantially related to CAD patients, as indicated by lower MPO levels in CAD patients compared to controls. While highlighting the potential of MPV and RDW% as predictors of severe atherosclerosis in CAD. Further research is needed to validate the diagnostic and prognostic value of RDW%, MPV, and MPO levels in CAD. TRIAL REGISTRATION: 15092021-9-12. Registered 15 September 2021.
