The results showed that hospital size and the status of being a training and research or a university hospital affected the technical efficiency ( < 0.

Is there any relationship between human foamy virus infections and familial Mediterranean fever?

Background: Familial Mediterranean fever (FMF) is generally defined as an autosomal recessive disease, characterized by the automatic activation of the innate immune system in the absence of a detectable pathogenic stimulant. We hypothesize that the pathogenic factors, besides the genetic causes, may affect the development of FMF symptoms. To test this hypothesis, we examined the effects of human foamy virus (HFV) positivity on the occurrence of the clinical symptoms of FMF.

Mutations in >60 genes have been identified to date as causative for RP, and additional candidate genes are assumed.

The relationship between familial Mediterranean fever gene (MEFV) mutations and clinical and radiologic parameters in multiple sclerosis patients.

Objective: Central nervous system (CNS) involvement in patients with familial Mediterranean fever (FMF) is considerably rare. Patients with FMF may exhibit clinical and radiologic symptoms similar to multiple sclerosis (MS). However, the impact of the Familial Mediterranean Fever Gene (MEFV) mutations on the clinical course of MS is not fully understood as yet.

The relationship between the presence of ADHD and certain candidate gene polymorphisms in a Turkish sample.

Due to the high heritability of attention-deficit hyperactivity disorder (ADHD), parents of children with ADHD appear to represent a good sample group for investigating the genetics of the disorder.

Interaction between periodontal disease and systemic secondary amyloidosis: from inflammation to amyloidosis.

Background: It has become increasingly clear in recent years that periodontal disease can cause a dramatic increase in the levels of markers of systemic inflammation, and that periodontal treatment can result in reduction in the levels of these markers. We have previously shown that the prevalence of moderate to severe periodontitis was significantly higher in patients with familial Mediterranean fever (FMF) with amyloidosis than in patients with FMF without amyloidosis. Thus, the aim of this study is to investigate if chronic periodontitis is associated with secondary amyloidosis in the Black Sea region of Turkey.

The polymorphisms in codon 72 of the tumor suppressor protein p53 (P53) gene and codon 655 of the human epidermal growth factor receptor 2 (HER2) gene have been suggested to play roles in most cancers. The purpose of this study was to investigate the association between common variants of HER-2 and P53 genes with breast cancer risk. Blood samples collected from 204 women with primary breast carcinoma and 192 healthy female controls were analyzed through polymerase chain reaction-restriction fragment length polymorphism methods.

Evaluation of pathergy test positivity in familial Mediterranean fever patients and comparison of clinical manifestations of FMF with Behçet's disease.

Familial Mediterranean fever (FMF) shares a number of features with Behçet's disease (BD), such as their common ethnic origin, etiopathogenetic mechanisms, symptoms, and treatment. Pathergy reaction is accepted as a major criterion in BD. We aimed to determine the frequency of pathergy positivity in FMF patients and compared clinical features between FMF and BD.

The aim of this study was to investigate the relationship between the TGFbeta1 T869C polymorphism and RA in a Turkish population.

Diffuse multicystic encephalomalacia in a preterm baby due to homozygous methylenetetrahydrofolate reductase 677 C-->T mutation.

Methylenetetrahydrofolate reductase catalyzes the formation of 5-methyltetrahydrofolate from 5,10-methylentetrahydrofolate and produces folate for the methylation of homocysteine to methionine. Due to insufficient conversion of homocysteine to methionine, plasma homocysteine levels increase in methylenetetrahydrofolate reductase deficiency. Homocysteine is an amino acid that contains a neurotoxic sulfur molecule and can induce neuronal apoptosis.

Background & Objective: Genetic polymorphisms in the vitamin D receptor (VDR) gene are related to bone mineral density, bone turnover, and diseases with bone loss. Alveolar bone loss is a key feature in periodontitis. The aim of this study was to determine whether severe generalized chronic periodontitis (CP) in a Turkish population was associated with polymorphisms in the VDR gene.

Background: Psoriasis is a multifactorial disease in which genetic and inflammatory factors play important roles. Leptin is classified as a cytokine and plays an important role in the regulation of the T-helper response. A common polymorphism in the promoter of the human leptin gene (G-2548A) may have a role in the pathogenesis of psoriasis.

MEFV mutations in patients with familial Mediterranean fever in the Black Sea region of Turkey: Samsun experience [corrected].

Prostate-specific antigen and 17-hydroxylase polymorphic genotypes in patients with prostate cancer and benign prostatic hyperplasia.

We investigated the association of prostate cancer (PCa) and benign prostatic hyperplasia (BPH) with genetic polymorphisms in prostate-specific antigen (PSA) (-158 G/A) and 17-hydroxylase (CYP17) (-34 T/C) genes in a Turkish population. In this study, we investigated the distribution of these polymorphisms in 148 PCa patients, 136 BPH patients, and 102 healthy individuals as controls. The polymorphisms were analyzed using polymerase chain reaction-restriction fragment length polymorphism assay.

Association of the polymorphisms in promoter and intron regions of the interleukin-4 gene with chronic periodontitis in a Turkish population.

Objectives: The etiology of periodontitis is related to the interaction between micro-organisms and host responses. Host modifying factors, such as genetic predisposition, may increase the severity of periodontitis. Recent works have shown that the levels of cytokine expression are regulated by genetic polymorphisms, and that these variations can interfere with progression of the disease.

Association of serotonin 2A receptor and lack of association of CYP1A2 gene polymorphism with tardive dyskinesia in a Turkish population.

The aim of this study was to investigate the possible association of serotonin 2A receptor gene (HTR2A) -1438 G/A polymorphism and CYP1A2 gene 163C/A polymorphism with tardive dyskinesia (TD) in a Turkish population. A total of 47 patients with persistent TD, 80 patients who were consistently without TD, and 100 healthy controls were included in this study.

Association of interleukin-10 gene polymorphisms with severe generalized chronic periodontitis.

Background: Interleukin-10 (IL-10), an anti-inflammatory cytokine, plays a role in periodontal disease by inhibiting synthesis of proinflammatory cytokines and stimulating protective antibody production. Genetic polymorphisms in the IL-10 gene might be useful as a marker to diagnose susceptibility to periodontitis. Therefore, the aim of this study was to investigate the association between IL-10 gene polymorphisms and severe generalized chronic periodontitis (CP) in a Turkish population.

Association of matrix metalloproteinase-9 promoter gene polymorphism with chronic periodontitis.

Background: Matrix metalloproteinases (MMPs) are related to tissue destruction and remodeling events in periodontal diseases. A single nucleotide polymorphism in the promoter region of human MMP-9 gene is associated with the risk of some inflammatory diseases. Therefore, the aim of this study was to investigate the association between MMP-9 promoter polymorphism and severe generalized chronic periodontitis in a Turkish population.
