Ischemic stroke is a multifactorial disease leading to severe long-term disability and it is the third leading cause of death in developed countries. Although many studies have been reported to elucidate etiological and pathological mechanisms of stroke, the genetic and molecular basis of disease remains poorly understood. Recent studies have shown that reactive oxygen species causing oxidative stress play a pivotal role in the pathogenesis of atherosclerosis that is the main cause of a group of cardiovascular diseases including ischemic stroke. In this study, we aimed to investigate the relationship between FMO3 Glu158Lys and Glu308Gly variants, and the risk of incidence of ischemic stroke in Turkish population. Two single nucleotide polymorphisms (SNPs) within the PMO3 gene were genotyped by using PCR-RFLP technique in a sample set of 245 cases and 145 controls. In the case-control analysis, no significant difference was observed between stroke patients and controls with respect to FMO3 Glu158Lys and Glu308Gly polymorphisms' genotype and allele frequency distribution. However, heterozygote 158Glu/Lys (OR = 6.110, P < 0.001) and 308Glu/Gly (OR = 6.000, P = 0.006) genotypes increase the risk of stroke 6 times in hypertensive subjects. On the other hand, the wild type genotypes 158Glu/Glu and 308Glu/Glu had 6.2-fold and 4.8-fold higher risk of ischemic stroke in obese subgroup, respectively. Our results clearly showed that the risk of hypertension-related ischemic stroke was higher in the heterozygote genotype carriers. This is the first study conducted regarding the association of FMO3 Glu158Lys and Glu308Gly genetic polymorphisms and ischemic stroke risk in Turkish population.

Intelligent Ratio: A New Method for Carrier and Newborn Screening in Spinal Muscular Atrophy Cavdarli, Busranur; Ozturk, Fatma Nihal; Guntekin Ergun, Sezen; ERGÜN, MEHMET ALİ; Dogan, Ozlem; Percin, Emriye Ferda (Mary Ann Liebert Inc, 2020-09-01) Aim:Spinal muscular atrophy (SMA) is an inherited, autosomal recessive neuromuscular disease that causes high morbidity and mortality. The prevalence is 1-2/100,000, while the incidence is 1/6000-1/10,000 among live births. Due to the high carrier frequency (1/40-1/60) of SMA, screening can prevent new cases. The aim of the current study was to present the development of a new, quantitative, real-time, polymerase chain reaction (PCR)-based screening test that uses an intelligent ratio (IR) for analyses, as ...
Etiology of senile osteoporosis - A hypothesis Atik, O. Sahap; Uslu, M. Murad; Eksioglu, Fatih; Satana, Tolgay (Ovid Technologies (Wolters Kluwer Health), 2006-02-01) Osteoporosis is a major health problem characterized by compromised bone strength predisposing patients to an increased risk of fracture. It may cause morbidity and mortality in elderly men and women. The etiologic factors that lead to senile osteoporosis still are unclear.
AIDS knowledge and educational needs of technical university students in Turkey Ungan, M; Yaman, H (Elsevier BV, 2003-10-01) AIDS is a main health problem of the recent century and is now considered a very important cause for mortality and morbidity among young people. The aim of this research is to determine the Turkish university students knowledge, sexual risk behavior, attitude towards AIDS and educational needs concerning AIDS. A cross-sectional exploratory design is utilized in this study. One thousand four hundred and twenty-seven university new registrants from the Middle East Technical University participated and answere...
Investigation of the association between genetic and activity polymorphisms of paraoxonase 1 and ischemic stroke risk Demirdöğen Can, Birsen; Adalı, Orhan; Department of Biochemistry (2007) Stroke is the third leading cause of death. Atherosclerosis in the carotid arteries is a risk factor for ischemic stroke. Oxidized low density lipoprotein (LDL) plays a central role in the progression of atherosclerosis. Human paraoxonase 1 (PON1), a high-density lipoprotein (HDL) associated serum esterase/lactonase, protects HDL and LDL from oxidative modifications. Thus, PON1 is protective against the development of atherosclerosis. PON1 gene has two functional coding region (192Q/R and 55L/M) and one pro...
Identification of Three Novel FBN1 Mutations and Their Phenotypic Relationship of Marfan Syndrome KAYHAN, GÜLSÜM; ERGÜN, MEHMET ALİ; Ergun, Sezen Guntekin; KULA, SERDAR; PERÇİN, Ferda Emriye (Mary Ann Liebert Inc, 2018-07-26) Background: Marfan syndrome (MS), a connective tissue disorder that affects ocular, skeletal, and cardiovascular systems, is caused by heterozygous pathogenic variants in FBN1. To date, over 1800 different pathogenic variants have been reported.
