Potential involvement of Helicobacter pylori from oral specimens in overweight body-mass index

Ribotyping of Helicobacter pylori from clinical specimens.

Ribotyping is a method used to type strains of bacteria by analyzing the restriction enzyme digestion patterns of the rRNA genes. This method was applied to 126 strains of Helicobacter pylori from 100 unrelated symptomatic patients who had endoscopies done and to 15 strains from 15 infected subjects from seven families. Analysis of the rRNA gene patterns revealed 77 distinct ribotypes from the ...

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

comparing the body mass index and fat mass index to identify overweight in children

background: the sensitivity and specificity of body mass index (bmi) percentiles of centers for disease control 2000 (cdc2000) standard was compared with child actual overweight which was identified by fat mass index (fmi) and overweight status in these children based on bmi and fmi. methods: in this case-control study, elementary school girls (aged 8-10 years) were recruited from schools of is...

Ghrelin, Helicobacter pylori and body mass: is there an association?

Eradication of Helicobacter pylori is accompanied by an array of metabolic and hormonal changes in the host. Weight gain following H. pylori eradication is a poorly understood phenomenon and probably results from an interaction between multiple factors. Ghrelin, a peptide hormone secreted by the stomach, is involved in the regulation of food intake and appetite and may account for some of these...

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...
