0163-6804/99/$10.00 © 1999 IEEE ith the increasing demands for mobile multimedia 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,(More)
Down syndrome candidate region 1 (DSCR1; also known as RCAN1 or Adapt78) has been shown to be induced by calcium overload and oxidative stress which are included in the pathogenic hallmarks of the ischemic diseases. After ischemic stroke, inflammatory responses play an important role in the exacerbation of neuronal loss. In this study, we investigated the(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)
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)
BACKGROUND In contrast to Western countries, the prevalence of Barrett's esophagus (BE) is still believed to be very low in the Far East. The aim of the present paper was to assess the prevalence of BE in Korea. METHODS Nine hundred and ninety-two consecutive patients undergoing their first diagnostic upper gastrointestinal endoscopies due to various(More)
Down syndrome candidate region 1 (DSCR1), an endogenous inhibitor of calcineurin, inhibits the expression of genes involved in the inflammatory response. To elucidate the molecular basis of these anti-inflammatory effects, we analyzed the role of DSCR1 in the regulation of NF-kappaB transactivation using glioblastoma cells stably transfected with DSCR1.4 or(More)
BACKGROUND Helicobacter pylori-associated gastrointestinal diseases have been widely recognized. The aims of this study were to investigate the interval change of seropositivity of H. pylori between 1998 and 2005 in Korean adult population and to find the factors related to H. pylori infection. METHODS Between January and December of 2005, a total of(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)
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 Angiopoietins play a critical role in the angiogenesis related to tumor growth in concert with vascular endothelial growth factor (VEGF), and enhanced expression of angiopoietin-2 has been reported in lung cancer tissue. METHODS Patients with lung cancer (n = 136) and healthy volunteers (n = 40) were enrolled. Serum angiopoietin-2 and VEGF(More)
