OBJECTIVE Polycystic ovary syndrome (PCOS) is a common female endocrine disorder associated with several risk factors of type 2 diabetes and cardiovascular diseases. The objectives of this study were to investigate the effects of omega-3 fatty acids on serum adiponectin levels and some metabolic risk factors in PCOS patients. METHODS This double-blind(More)
This cross-sectional study examined the burden of cardiovascular diseases (CVDs) using serum 25-hydroxyvitamin D (25[OH]D) and prevalence of hypovitaminosis D in adults with CVDs using data from NHANES 2001 to 2004. Serum 25(OH)D levels were divided into 3 categories (> or =30, 20 to 29, and <20 ng/ml), and hypovitaminosis D was defined as vitamin D <30(More)
The aim of this study was to evaluate the accuracy of measuring bone thickness surrounding dental implants and the reliability of assessing existence and completion of osseous integration of augmentation material using a cone beam computed tomography (CBCT) system. In jaws of foxhounds, artificial defects were regenerated by guided bone regeneration and(More)
To assess inter-scan reproducibility of coronary calcium measurements obtained from Multi Detector-Row CT (MDCT) images and to evaluate whether this reproducibility is affected by different measurement protocols, slice thickness, cardiovascular risk factors and/or technical variables. Cross-sectional study with repeated measurements. The study population(More)
BACKGROUND/OBJECTIVES Folate, pyridoxine and cobalamin are coenzymatically essential in one-carbon methyl metabolism, and their deficiencies could explain some alterations during breast carcinogenesis. We aimed to evaluate the validity of folate, pyridoxine and cobalamin estimates from a food frequency questionnaire (FFQ) on the basis of their corresponding(More)
BACKGROUND Apart from the crucial role of micronutrients like copper, iron, and zinc in the functions of body enzymes, it seems that changes in the serum levels of these biomarkers may play a role in the pathogenesis of oral cancer. The aim of this study was to measure the serum levels of ferritin, copper, and zinc in patients with oral malignancies. (More)
