Epstein-Barr virus-associated gastric carcinomas: relation to H. pylori infection and genetic alterations.
BACKGROUND & AIMS The association of Epstein-Barr virus (EBV) and gastric carcinomas (GCs) has been shown to vary among different populations and certain histological subtypes. Few studies haveExpand
Genetic alterations in gastric cancer: relation to histological subtypes, tumor stage, and Helicobacter pylori infection.
BACKGROUND & AIMS A different spectrum of genetic changes including p53, c-erbB-2, c-met, adenomatous polyposis coli (APC), and deleted in colorectal cancer (DCC) is involved in gastric cancer (GC).Expand
Distinct clinicopathologic and genetic profiles in sporadic gastric cancer with different mutator phenotypes
A subset of sporadic gastric cancers (GC) exhibits microsatellite instability (MSI). To define the precise role of MSI in GC, a total of 100 patients with sporadic GC were classified into threeExpand
Loss of imprinting and overexpression of IGF2 gene in gastric adenocarcinoma.
Both insulin-like growth factor II (IGF2) and H19 gene are located on chromosome 11p15.5 in close vicinity to each other, and are imprinted on different parental alleles. Although the exact mechanismExpand
Gastric cancer risk in relation to Helicobacter pylori infection and subtypes of intestinal metaplasia.
Helicobacter pylori (H. pylori) infection and intestinal metaplasia (IM) are each associated with an increased risk of gastric cancer (GC). To explore further the influences of H. pylori and IM onExpand
Low frequency of bacteremia after endoscopic mucosal resection.
BACKGROUND Endoscopic mucosal resection has become a popular alternative for the treatment of early-stage neoplasia of the gastrointestinal tract. However, there are still no data on the frequency ofExpand
Clinicopathological significance of altered loci of replication error and microsatellite instability-associated mutations in gastric cancer.
Replication errors (RERs) judged by microsatellite instability and its associated mutations have been recognized as an important mechanism in tumorigenesis of gastric cancers (GCs). To gain a deeperExpand
Pancreaticobiliary diseases associated with anomalous pancreaticobiliary ductal union.
BACKGROUND Anomalous pancreaticobiliary ductal union (APBDU) is associated with different pancreaticobiliary diseases. The aim of this study is to clarify the frequency with which it occurs and itsExpand
A simple, sensitive, non-stimulated photon counting system for detection of superoxide anion in whole blood
A simple, sensitive, non-stimulated assay was developed to measure the superoxide anion concentration in whole blood, using an ultra-sensitive chemiluminescence (CL) analyzer, and lucigninExpand
Anomalous pancreaticobiliary ductal union--an etiologic association of gallbladder cancer and adenomyomatosis.
BACKGROUND/AIMS Anomalous pancreaticobiliary ductal union (APBDU) has been proposed as a risk factor of gallbladder cancer. To clarify the frequency and the subtype distribution of APBDU in patientsExpand
