AIMS The objectives of this study were to determine the role of oxidative stress in intrauterine growth restriction (IUGR) and to investigate the possible molecular mechanism(s) leading to oxidant stress in IUGR. METHODS Parameters of the oxidative and antioxidant system were evaluated in maternal plasma, umbilical cord blood, and placental tissue of(More)
Tumor growth, which employs a number of regulators, requires the formation of new blood vessels. The most important regulators are vascular endothelial growth factor (VEGF) and angiopoietin-2 (ANGPT-2). DNA sequence variations in VEGF and ANGPT-2 genes may lead to altered productions and/or activities of these genes. In this study, we aimed to determine the(More)
BACKGROUND DNA sequence variations in HIF-1 alpha gene might yield changes both in the production outcomes and in the activities of the gene. Overexpression of the HIF-1 alpha subunit, resulting from intratumoral hypoxia and genetic alterations, has been demonstrated in common human cancers and is correlated with tumor angiogenesis and patient mortality. In(More)
The aim of this study was to measure oxidant/antioxidant status in maternal and cord plasma and in placental tissue in gestational diabetes and to correlate the results with the quality of glycemic control of the mother. To achieve this, blood and placental tissue samples have been obtained from pregnant women with gestational diabetes mellitus (GDM) and(More)
In order to compare the performance of leukocyte esterase and nitrite urine dipstick tests with enhanced urinalysis (uncentrifuged urine white blood cell count/mm(3) plus Gram stain) in detecting asymptomatic bacteriuria in obstetric patients, clean-catch midstream urine specimens were collected from 250 consecutive asymptomatic pregnant women. Ten of the(More)
AIM To investigate the characteristics of menopausal population who gets free first step health-care services from government facilities in the Central Anatolia Region of Turkey. METHODS One thousand and forty-nine pre- (N = 403) and post (N = 646)-menopausal females were interviewed with a questionnaire in five different facilities during 2 weeks. (More)
AIM This study was designed to examine the relationship between homocysteine (Hcy), lipoprotein levels and insulin resistance in obese and non-obese patients with polycystic ovary syndrome (PCOS). MATERIALS AND METHODS Eighty-five patients (38 obese, 47 non-obese) with PCOS and 50 healthy subjects (25 obese, 25 non-obese) were included in the study. PCOS(More)
Secreted aspartyl proteinase (Sap) distribution among differentC. albicans isolates was determined usingSAP-specific primers in polymerase chain reaction (PCR) assay.SAP1, SAP2, andSAP3 were detected in 13 of 40 (32.5 %),SAP4 in 38/40 (95 %),SAP5 were detected in 30/40 (75 %),SAP6 in 23/40 (57.5 %) ofC. albicans strains isolated from blood(More)
Objective: To compare the platelet count and mean platelet volume (MPV) values of pregnancies diagnosed with gestational diabetes with those of healthy pregnancies. Material—method: Between June 2003 and September 2004, 100 healthy pregnancies and 100 pregnancies with gestational diabetes were studied at Gazi University, Department of Obstetrics and(More)
We described a fetus who is delivered at 32.weeks of gestation by elective cesarian because of the fetal anhydria and unilateral hydronephrosis.A breech coming,1950 gr, 44 cm a newborn was delivered with multiple malformations and postpartum he didn't cry and siyanosis was appeared. After first interventions the newborns respiration didn't start and(More)
