This study assessed the screening rates for gastric cancer by two different screening methods, upper gastrointestinal (UGI) series and endoscopy; intentions to undergo future gastric cancer screening; and the preferred method of screening. The study population was derived from the 2006 Korean National Cancer Screening Survey. The Korean National Cancer Screening Survey is an annual cross-sectio...

In recent years there have been significant advances in the field of Unsupervised Grammar Inference (UGI) for Natural Languages such as English or Dutch. This paper presents a broad range of UGI implementations, where we can begin to see how the theory has been put in to practise. Several mature systems are emerging, built using complex models and capable of deriving natural language grammatica...

A series of new fluorene bisamide derivatives were synthesized through multi-component Ugi reaction and tested for their in vitro anti-mycobacterial activity. The structures of the products 5a-w were deduced from their IR, 1H NMR, and 13C NMR spectra. Elemental analyses (CHN) for novel compounds (5a, 5d, 5f, 5h, 5k, 5l, 5p, 5s, 5t, 5v, 5w) was done to. These compounds were evaluated as anti-bac...

BACKGROUND Nonsteroidal anti-inflammatory drug (NSAID) use has been associated with a reduced risk of colon cancer; further epidemiologic data appear consistent for stomach and esophageal adenocarcinomas. Yet, data on potential confounding effects by upper gastrointestinal tract (UGI) disorders on adenocarcinomas of the UGI are limited. METHODS This study recruited newly diagnosed patients wi...

OBJECTIVE Upper gastrointestinal (UGI) bleeding is one of the most life-threatening complications, in up to 25% of persons with hemophilia (PWH). Recurrent bleeding is common and can be caused by the Helicobacter pylori infection. Our aim was to evaluate the role of H. pylori infection in UGI bleeding in PWH. MATERIAL AND METHODS Ninety patients with hereditary bleeding disorders, 30 patients...

BACKGROUND AND AIMS Examination of the laryngopharyngeal area is not always performed during routine upper gastrointestinal (UGI) endoscopies although older studies reported pathological findings in 0.9-3.5% of cases. The aim of our study was to prospectively evaluate the positive and negative predictive value of screening the laryngopharyngeal area during routine UGI endoscopy. METHODS All p...

PURPOSE Cancer of the upper digestive tract (uGI) is a major contributor to cancer-related death worldwide. Due to a rise in occurrence, together with poor survival rates and a lack of diagnostic or prognostic clinical assays, there is a clear need to establish molecular biomarkers. EXPERIMENTAL DESIGN Initial assessment was performed on urine samples from 60 control and 60 uGI cancer patient...
