AIM This study used the OLGA system to characterize the histology pattern of gastritis in dyspeptic outpatients with a mean age of 45 years from regions with different gastric cancer risks. BACKGROUND Several classification systems have been purposed for understanding the status of the gastric mucosa. Currently, the Sydney system is the most widely employed. Nevertheless, the applicability of...

Résumé La gastrite chronique à Helicobacter pylori (H pylori) présente un risque de cancérisation en rapport avec l'atrophie et la métaplasie intestinale. Deux nouvelles classifications, OLGA (Operative Link on Gastritis Assessment) et OLGIM (Operative Link on Gastritic Intestinal Metaplasia assessment) ont été proposées pour individualiser les formes à haut risque évolutif (stades III et IV). ...

The protein composition of Alteromonas sp. strain KE10 cultured at two different organic-nutrient concentrations was determined by using two-dimensional polyacrylamide gel electrophoresis. The cellular levels of three proteins, OlgA, -B, and -C, were considerably higher in cells grown in a low concentration of organic nutrient medium (LON medium; 0.2 mg of carbon per liter) than cells grown in ...

Gastric intraepithelial neoplasia (IEN; formerly dysplasia) is an advanced precancerous lesion. Lesions indefinite for IEN mimic the IEN phenotype but lack some morphologic attributes of IEN. Indefinite for IEN lesions may arise in native foveolae (atypical foveolar hyperproliferation [aFH]) or intestinalized glands (hyperproliferative intestinal metaplasia [HIM]). The clinicopathologic outcome...
