ith the increasing demands for mobile multime-dia services, future wireless networks will adopt micro/picocellular architectures in order to provide the higher capacity needed to support broadband services under the limited radio spectrum [1]. Due to its flexible bandwidth allocation , efficient multiplexing of bursty traffic, and provision of a wide range(More)
OBJECTIVE Postpolypectomy surveillance guidelines for colorectal cancer introduced the concept of 'risk stratification'; however, few studies have been conducted for validation of its usefulness. The aim of this study was to assess the 5-year incidence of advanced neoplasia recurrence based on the risk stratification scheme of the guidelines and to identify(More)
This study was done based on screening test data accumulated from 1994 to 2001 for studying of risk factor related with liver disease and prediction model of liver disease. In the existing study related with liver, the main current is studying on liver cancer, not on liver disease, previous step into liver cancer. As a result of estimating prediction model(More)
BACKGROUND Colonoscopy is the criterion standard for screening of colorectal neoplasms. Nonetheless, a substantial miss rate with conventional, white-light colonoscopy (WL) remains a challenge. OBJECTIVE To assess whether Fuji Intelligent Color Enhancement (FICE) can detect more adenomas than WL in screening colonoscopy. DESIGN Prospective, randomized(More)
BACKGROUND Peroxiredoxins (Prxs) have been implicated in regulating many cellular processes including cell proliferation, differentiation and apoptosis. However, the pathophysiological significance of Prx proteins, especially in lung disease, has not been defined. Therefore, the authors investigated the distribution and expression of various Prx isoforms in(More)
OBJECTIVES Colorectal adenoma is known to be associated with obesity, but the association between colorectal adenoma and visceral adipose tissue (VAT) area measured by abdominal computed tomography (CT) has not been documented clearly. In addition, the relationship between insulin resistance and colorectal adenomas, which underlies the mechanism that links(More)
BACKGROUND Apoptosis is thought to play an important role in the development of acute respiratory distress syndrome (ARDS). We evaluated the bronchoalveolar lavage (BAL) fluid from ARDS patients focusing on apoptosis. METHODS The study enrolled 31 ARDS patients and 20 healthy controls. BAL fluid levels of caspase-cleaved cytokeratin-18 (CK-18) and soluble(More)
OBJECTIVE To examine the independent effect of metabolic syndrome (MS) on nephrolithiasis (NL) even with changes in MS status over time. METHODS From 2002-2003, 3872 men who were reexamined annually or biannually until 2009 were enrolled in the analysis and observed for development of NL. The examination included anthropometric measurements, biochemical(More)
PURPOSE To analyze the independent effect of metabolic syndrome (MS) on nephrolithiasis (NL) despite differences in gender compared with the known lithogenic factors. MATERIALS AND METHODS From 1995 to 2009, 40,687 Koreans were enrolled in the study and observed for the development of NL at a health promotion center. The examination included(More)
BACKGROUND/AIMS The role of Helicobacter pylori in gastroesophageal reflux disease remains still controversial and the effect of the organism on severity of reflux esophagitis have been rarely issued. The aim of this study was to investigate the relationship between H. pylori infection and reflux esophagitis, and especially the severity of reflux(More)
