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)
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)
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)
The survival of a recent series of 823 cirrhosis patients who were followed up for a mean of 48 months was analyzed. Cirrhosis was ascribed to alcohol (26%), hepatitis virus B (58%), hepatitis virus C (11%) or both (2%), or was cryptogenic (3%). Features of decompensation were observed in 51% of the patients at entry, and newly developed in 44% of(More)
Biochemical studies have revealed that some normal cells express the Le" trisaccharide Gal£l-»4(Fucal-»3)GlcNAc either on short-chain fu-colipids or as a single immunodeterminant on glycolipid oligosaccharide side chains. Cancer cells, including those from colonie adenocarcinomas, express this antigen on longer type 2 blood group side chains as(More)
BACKGROUND/AIMS Oxidative stress results in protein oxidation and is implicated in carcinogenesis. Sulfiredoxin (Srx) is responsible for the enzymatic reversal of inactivated peroxiredoxin (Prx). Nuclear factor E2-related factor 2 (Nrf2) binds to antioxidant responsive elements and upregulates the expression of Srx and Prx during oxidative stress. We aimed(More)
PURPOSE Following the introduction of medical therapy for benign prostatic hyperplasia (BPH), we determined the effect of the change in trends in medical therapy on the indication and outcome of surgical intervention for BPH. MATERIALS AND METHODS We compared the basic characteristics of, weight of resected tissue of, transfusions in, and postoperative(More)
BACKGROUND/AIMS Peroxiredoxin (Prx) belongs to a ubiquitous family of antioxidant enzymes that regulates many cellular processes through intracellular oxidative signal transduction pathways. Silica-induced lung damage involves reactive oxygen species (ROS) that trigger subsequent toxic effects and inflammatory responses in alveolar epithelial cells(More)
The LeY determinant, a difucosylated type 2 blood group-related antigen, is a positional isomer of the Leb blood group antigen and a fucosylated derivative of the Lex antigen. The Le" antigen behaves like an oncodevelopmental tumor-associated antigen in human colon cancer, and extended polyfucosyl Lex antigens are more specific for colon cancer tissues than(More)
BACKGROUND/AIMS The purpose of this study was to evaluate the clinicopathologic characteristics of colon cancers detected at the SOK Sokpeynhan Internal Medical Network, a nationwide system of primary health care institutions. METHODS We analyzed 579 colon cancer patients diagnosed using colonoscopy at the SOK network from January 2011 through December(More)
