Öğe Determination of risk factors in obese and non-obese patients with coronary artery disease(Acta Cardiologica, 2005) Yologlu, S; Sezgin, AT; Sezgin, N; Ozdemir, R; Yesilada, E; Topal, EObjective - Obesity is a complex multifactorial chronic disorder recently classified by the American Heart Association (AHA) as a modifiable risk factor for coronary artery disease (CAD). This study was designed to assess conventional and novel risk factors in obese and non-obese patients with CAD. Methods and results - This study evaluates the association between conventional and novel coronary risk factors and CAD in obese and non-obese patients by using multivariate stepwise logistic regression analysis. The obese CAD group was identified by the following predictors of CAD: age, sex, hypertension, diabetes mellitus, smoking, family history of CAD, low level of HDL cholesterol, high LDL cholesterol, high C-reactive protein, high homocysteine. In a non-obese CAD group, the identified predictors of CAD were age, sex, hypertension, smoking, family history of CAD, levels of high C-reactive protein, and high homocysteine. Hypertension was found to be the strongest predictor for both obese (OR: 39.91, 95% confidence intervals (Cl): 5.51-280.3, p < 0.001) and non-obese (OR: 14.39, 95% CI: 4.4-25.8, p < 0.001) patients with CAD. Conclusions - From our data, we conclude that hypertension appears to be the strongest independent predictor of CAD regardless of body mass index (BMI).Öğe Genotoxic activity of vinasse and its effect on fecundity and longevity of Drosophila melanogaster(Springer Verlag, 1999) Yesilada, E[Abstract Not Available]Öğe Genotoxicity testing of four textile dyes in two crosses of Drosophila using wing somatic mutation and recombination test(Taylor & Francis Ltd, 2005) Dogan, EE; Yesilada, E; Ozata, L; Yologlu, SIn this study, four textile dyes, namely Astrazon Yellow, Red, Blue, and Black, were tested for their genotoxic effects in the wing cells of Drosophila melanogaster. Two crosses were used, the standard cross (ST) and the improved high-bioactivation cross (HB), the latter being characterized by increased sensitivity to the genotoxic effects of promutagens and procarcinogens. Three-day-old larvae were exposed to different concentrations of dyes. Commonly known mutagens were applied as positive controls. All concentrations of textile dyes, ethyl methanesulfonate ( EMS), and urethane caused a decrease in survival proportional to concentration used. EMS and urethane caused an increase in the number of all types of spots in both standard and high-bioactivation crosses. Compared to ST crosses, the number of induced spots in the HB cross treated with urethane was considerably high. Treatment of the standard and the high-bioactivation crosses with textile dyes gave positive results, apparent from increase in the frequency of the small single spots. Yellow and red dyes also increased the number of large single spots in both crosses, whereas the twin spots were positive only at the highest dose of yellow dye. All these results indicate that D. melanogaster wing spot test can be recommended as a suitable in vivo test for the determination of genotoxicity of textile dyes.Öğe Genotoxicity testing of some metals in the Drosophila wing somatic mutation and recombination test(Springer-Verlag, 2001) Yesilada, E[Abstract Not Available]Öğe Increased micronucleus frequencies in peripheral blood lymphocytes in women with polycystic ovary syndrome(Bio Scientifica Ltd, 2006) Yesilada, E; Sahin, I; Ozcan, H; Yildirim, IH; Yologlu, S; Taskapan, CObjective: We aimed to assess possible genomic instability in women with polycystic ovary syndrome (PCOS). Design: The frequency of micronuclei in cultured peripheral lymphocytes was used as a biomarker of genomic instability in somatic cells. Methods: Nineteen women, diagnosed with PCOS and 19 healthy female volunteers of corresponding ages and body-mass index (BMI) were included in the study. Micronuclei frequencies were assessed in cytokinesis-blocked lymphocytes. Results: The frequency of micronucleated cells (per thousand) was 9.00 (5.00) (interquartile range in parentheses) for patient group and 3.0 (3.0) for the control group (P < 0.0001, Mann-Whitney U-test). The serum levels of follicle-stimulating hormone (FSH), estradiol, prolactin, glucose and dehydroepiandrosterone sulfate (DHEAS) and the homeostasis model of assessment of insulin resistance (HOMA-IR) were not different between the two groups (P > 0.05). Serum total testosterone, luteinizing hormone (LH) and insulin levels and hirsutism score in the PCOS group were significantly (P = 0.007, P < 0.0001, P = 0.009 and P < 0.0001 respectively) higher than those of the control group (2.3 (2.1) nmol/l vs 1.7 (0.4) nmol/l; 8.5 (5.88) mU/ml vs 4.8 (4.4) mU/ml; 6.8 (5.1.) mu U/ml vs 9.7 (4.2) mu U/ml; 19.5 (6.5) vs 4.0 (2.5) respectively). However, the mean level of sex hormone-binding globulin (SHBG) in PCOS group was significantly (P = 0.004) lower than in control group (36.4(22.6) nmol/l vs 48.6(25.2) nmol/l respectively). Conclusion: These findings suggest that women with PCOS have a high incidence of genomic instability, and this condition is positively correlated with the hirsutism score, BMI. LH and serum total testosterone and insulin levels, and is negatively correlated with SHBG.Öğe Studies on the toxic and genotoxic effect of olive oil mill wastewater(Inst Lebensmitteltechnologie Analytische Chemie, 1999) Yesilada, E; Özmen, M; Yesilada, ÖAcute lethality and genotoxic effects of olive oil mill wastewater (OOMW) were studied. OOMW showed lethality on amphibian tadpoles of Rana ridibunda and Bufo viridis. The LC50 values were found to be 2.59% and 2.12% for R. ridibunda and B. viridis, respectively. OOMW had also genotoxic effect on Drosophila melanogaster. Treatment of OOMW (1:9 v/v OOMW:dH(2)O) with Funalia trogii, reduced the phenol, COD and color contents of this waste and decreased the toxicity in tadpoles.
