Exfoliation of Helicobacter pylori from Gastric Mucin by Glycopolypeptides from Buttermilk

Prevalence of Coinfection Helicobacter pylori with Non-Helicobacter pylori Helicobacters Species in Patients Suffering from Gastric Diseases in Iran

Introduction: In addition to Helicobacter pylori, non-Helicobacter pylori helicobacters (NHPHs) have been diagnosed in the humans stomach that caused gastrointestinal diseases. This study aimed to evaluate the coinfection of H. pylori with NHPHs species in patients with gastric disorders in Iran.   Materials & Methods: This cross-sectional study was performed on 421 gastric biopsies form dysp...

PCR and RFLP Analysis for Identification and Typing of Helicobacter pylori Strains from Gastric Biopsy Specimens

Detection of Helicobacter pylori from Gastric Biopsy Samples by Culture, Polymerase Chain Reaction and Histopathological Methods in Eastern Turkey

The aims of this study were to detect Helicobacter pylori (H. pylori) by culture, polymerase chain reaction (PCR) and histopathological methods, to determine the prevalence of active H. pylori infection in Elazig Province, East of Turkey and to evaluate the relationship between H. pylori infection and sex. Antrum and corpus samples of 184 Turkish patients (85 male and 99 female, age range 17 to...

Histological Changes In Gastric Biopsies From Helicobacter Pylori-Infected Patients With And Without Peptic Ulcer

  Background and Objective: Long period risk of gastric carcinoma in people affected with chronic Helicobacter pylori gastritis is 5 times more than normal people. Perhaps histological changes due to helicobacter pylori infection could be used for screening people at risk of gastric carcinoma and peptic ulcer. Materials and Methods: This study has been carried out as a cross...

Affinity purification of Helicobacter pylori urease. Relevance to gastric mucin adherence by urease protein.

A simple, reproducible and high yield method of Helicobacter pylori urease enzyme purification was developed using a heparinoid (Cellufine sulfate) affinity gel. The purification method involved two sequential steps using the same gel that takes advantage of the differential affinity of urease to the heparinoid at two levels of hydrogen ion concentration. SDS-polyacrylamide gel electrophoresis ...
