BACKGROUND/AIMS The purpose of upper gastrointestinal endoscopy in gastroesophageal reflux disease is to detect the complications; both Barrett esophagus and erosive esophagitis are common in developed countries. We aimed to investigate the ratio of esophageal complications in gastroesophageal reflux disease and the relationship between reflux symptoms and(More)
BACKGROUND/AIMS Globus hystericus is a feeling of tension in the throat, irrelevant of swallowing, persisting for at least 12 weeks. Since the cause of globus hystericus is not fully described, the treatment is controversial. We aimed in this study to determine the symptoms of gastroesophageal reflux disease, upper gastrointestinal endoscopic findings,(More)
BACKGROUND AND AIMS Gastroesophageal reflux disease (GERD) is caused by the reflux of gastric contents into the esophagus. Narrow band imaging (NBI) facilitates mucosal surface evaluation and may improve the endoscopic diagnosis of GERD. The diagnosis of GERD is based on the combination of clinical symptoms, endoscopic findings, and histological changes. In(More)
Colorectal adenomatous polyp (CRAP) is a major risk factor for the development of sporadic colorectal cancer (CRC). Histone modifications are one of the epigenetic mechanisms that may have key roles in the carcinogenesis of CRC. The objective of the present study is to investigate the alternations in the defined histone modification gene expression profiles(More)
BACKGROUND/AIMS Gastric cancer (GC) is the second most common malignancy worldwide, with a high mortality rate. The incidence of GC has declined in the western countries during the last decades. The glutathione S-transferases comprise a group of enzymes that are critical in the detoxification of carcinogens. In this study we aimed at the relationship GSTP-1(More)
Ulcerative colitis (UC) is an important risk factor for colorectal cancer (CRC). Histone modifications are one of the epigenetic mechanisms that may have key roles in the carcinogenesis of CRC. At present, there are no studies comparing histone modification patterns of UC and CRC in the literature. Therefore the aim of the present study was to investigate(More)
BACKGROUND Helicobacter pylori, intestinal metaplasia (IM), and gene methylation play important roles in gastric carcinogenesis. However, the association among H. pylori infection, IM, gastric cancer (GC), and gene methylation is not fully understood. Cell cycle control involving retinoblastoma 1 (RB1) gene is one of the main regulatory pathways reported to(More)
Studies about leukocytapheresis have emerged with the need of search for alternatives to conventional treatment in inflammatory bowel diseases (IBD). Leukocytapheresis is a novel non-pharmacologic approach for active ulcerative colitis (UC) and Crohn's disease (CD), in which leukocytes are mechanically removed from the circulatory system. Patients with(More)
Direct-acting antiviral agents (DAA) such as NS3 protease inhibitors is the first class of drugs used for chronic hepatitis C (CHC) treatment. NS3 inhibitors (PI) with low genetic barrier have been approved to be used in the CHC genotype 1 infections, and in the treatment of compensated liver disease including cirrhosis together with pegile interferon and(More)
BACKGROUND Psychological factors and psychiatric disorders play a role in a variety of gastrointestinal illnesses, including esophageal diseases. AIM The aim of the present study was to evaluate the frequency of gastroesophageal reflux disease symptoms in patients with schizophrenia in Turkey. PATIENTS AND METHODS Ninety-eight patients with(More)
