AIM The present study was designed to examine the relationship between Pro12Ala polymorphism of the peroxisome proliferator-activated receptor-gamma gene (PPAR-gamma) and clinical and hormonal characteristics in women with polycystic ovary syndrome (PCOS). MATERIALS AND METHODS One hundred patients with PCOS and 100 healthy subjects were included in the(More)
Adequate copper (Cu2+) concentrations are required for plants; however, at higher concentrations it can also cause multiple toxic effects. In the present study, lipid peroxidation, hydrogen peroxide levels as well as ascorbate peroxidase (APX: EC 1/11/1/11) and catalase (CAT: EC activities were determined in Lycopersicum esculentum Mill. and(More)
BACKGROUND Cytogenetic, molecular and epigenetic changes are all known to take place in the pathogenesis of meningiomas. In this study, we aimed at investing methylation of MGMT (DNA repair), CDKN2A (cell cycle control), GSTP1 (detoxification), and THBS1 (angiogenesis inhibitor) genes, which are known to be unmethylated in normal tissue, in meningioma(More)
OBJECTIVE To investigate the association between nasal polyposis (NP) and single nucleotide polymorphisms of the proinflammatory cytokines IL (interleukin) 1alpha (the IL1A gene), IL-1beta (the IL1B gene), and tumor necrosis factor alpha (the TNFA gene). DESIGN Prospective case-control trial. SETTING Tertiary referral center. PATIENTS Eighty-two(More)
AIM Although the association between adiponectin gene polymorphisms and insulin resistance has been investigated in many studies, there are only a few studies, which have investigated adiponectin gene polymorphisms in patients with polycystic ovary syndrome (PCOS). The objectives of this study were to determine the frequency of T45G polymorphisms localised(More)
Familial Mediterranean fever (FMF) is characterized by recurrent fever, serositis, and arthritis. Due to the abundance of mutations and clinical heterogeneity of the disease, different screening methods have been developed. In this study, we aimed to compare our findings of mutations determined by polymerase chain reaction-restriction fragment length(More)
Diabetes mellitus is a multifactorial metabolic disease, caused by the complete or relative absence of insulin hormone, which results in the deterioration of carbohydrate, protein, and lipid metabolism. The PON1 55 and 192 polymorphisms have been reported to be associated with type 2 diabetes and its complications. In this study, the involvement of the PON1(More)
Inflammatory bowel disease (IBD) with ulcerative colitis (UC) and Crohn's disease (CD) as the most common forms is an inflammation of the gastrointestinal tract. Familial Mediterranean fever (FMF) is another inflammatory disease as well. In the current study we studied FMF gene mutations in 47 patients with IBD and 25 healthy individuals to investigate the(More)
CONTEXT Propranolol, atenolol, and ICI118,551 are non-selective β-adrenergic receptor (AR), β1-AR, and β2-AR antagonists, respectively. OBJECTIVE We investigated the efficacy of propranolol, atenolol, and ICI118,551 on proliferation, migration, and invasion of non-stimulated breast (MCF7), colon (HT-29), and hepatocellular (HepG2) cancer cells.

Clopidogrel is widely used in cardiovascular medicine, and is believed to play an important role in the pathogenesis of many cardiovascular disease processes. In particular, patients undergoing coronary stenting, who are commonly treated with clopidogrel, are candidates for in-stent restenosis. This is mainly caused by neointimal hyperplasia, so it is(More)
