Helicobacter pylorii

BACKGROUND: Gastric cancer is one of the leading causes of cancer death, particularly in Asia and South America. Screening and eradication of Helicobacter pylori is recognised as an advantageous solution to reduce the disparities in the incidence of this cancer. However, the deployment of such policies is not yet sufficiently advanced in high-incidence areas. Our study aimed to show the acceptability and feasibility of an index-case method to implement a screening and eradication policy in high-risk populations living in Taiwanese indigenous communities...

PURPOSE: Worldwide, gastric cancer (GC) is the 5th cancer with the highest incidence and the 4th in mortality. To reduce it, one strategy is to diagnose preneoplastic lesions (PNL): atrophic gastritis (AG), intestinal metaplasia (IM), and dysplasia (DYS); to form risk groups on which to focus surveillance efforts as are first-degree relatives (FDR). The aim of this study was to determine prevalence of gastric PNL in FDR of patients with GC, and to study association with sex, age, and Helicobacter pylorii (Hp) infection...

Infection with Helicobacter pyloriis the most common cause of stomach and duodenal ulcers. About more than 80 % of people are infected with H. pylori in developing countries. H. pylori uses urease enzyme product "ammonia" in order to neutralize and protect itself from the stomach acidic condition and urease enzyme activity has been shown to be essential to the colonization of H. pylori. Inhibitory activity of 20 traditional medicinal plants were examined and evaluated against Jack bean urease activity by Berthelot reaction to obtains natural sources of urease inhibitors...

Helicobacter pylori (H. pylori) has been associated with humans for millions of years and its association wih gastroduodenal diseases has well been established. Research explosion has added vastly to the current dimensions. The new and unusual pattern of involvement in the form of diffuse duodenal nodular lymphoid hyperplasia (DDNLH) due to specific strain of H. pylorii has been reported from Kashmir recently, which heckles early recognition and treatment and on the other hand, we continue to face challenges so far as the prevention of carcinoma of stomach, a worst sequlae of H...

Helicobacter pylori (H. pylorii) changes from a spiral form to coccoid by the aggravation of its surrounding environment. It was believed that the coccoid H. pylori indicated to be dying or becoming dormant. However, the implication of coccoid formation, itself, has not yet been elucidated. In this study, both the ultrastructural changes and the localization of the intracellular DNA were observed during coccoid formation in H. pylori. Some coccoid forms were observed to adhere to each other during transformation from the spiral form...

BACKGROUND: Since 2002, we have performed 350 laparoscopic Roux-en-Y gastric bypasses (LRYGB). We decided to evaluate the laparoscopic mini-gastric bypass (LMGB), an operation reported as effective, yet simpler than LRYGB. It consisted of a long lesser curvature tube with a terminolateral gastroenterostomy, 200 cm distal to the Treitz ligament. METHODS: From October 2006 to November 2007, 100 patients (23 men and 77 women) underwent LMGB. The mean age was 40.9 +/- 11...

AIM: To construct a live attenuated Salmonella typhimurium (S. typhimurium) strain harboring the H pylori neutrophil activating protein (HP-NAP) gene as an oral recombinant DNA vaccine, and to evaluate its immunogenicity. METHODS: By genetic engineering methods, the genomic DNA of H pylori was extracted as a template. The total length of the HP-NAP gene was amplified by polymerase chain reaction (PCR) and cloned into pBT vector for sequencing and BLAST analysis, then subcloned into a eukaryotic expression vector pIRES followed by PCR identification and restriction enzyme digestion...

BACKGROUND: The mucosa distal to the endoscopic mucosal change zone can have easily diagnosed early alterations, in patients with chronic gastroesophageal reflux. AIM: To determine the type of mucosa existent in the zone distal to the squamous-columnar junction in patients with chronic gastroesophageal reflux without intestinal metaplasia. PATIENTS AND METHODS: One hundred thirty four controls and 208 patients with chronic gastroesophageal reflux lasting two years were studied...

The established risk factors for ischemic stroke do not sufficiently explain all clinical and epidemiological features of the disease, such as the winter peak of stroke incidence, the decline of stroke during this century and the time point of cerebral ischemia. A role of infectious disease as stroke risk factor may partly explain above features. Several case-control studies with both hospital and population control groups showed that acute infection within the preceding week and mainly respiratory infection of both viral and bacterial origin increase the risk of cerebral ischemia independent from other risk factors (odds ratio 2...

The aim of the paper comprised: 1) estimating the incidence of Helicobacter pylori (H. pylori) infection in subjects directed to undergo endoscopic examination due to ailments involving the upper segments of the alimentary tract, 2) determination of the degree of H. pylorii infection detectability on the basis of invasive methods (bacterial culture, urease test and histological examination of specimens stained by Giemsa method) and non-invasive (serological investigation, skin test) with endoscopic image and histopathologic changes in gastric mucosa being talken into consideration, 3) assessing the titer of class IgG anti-H...

Are the emergent pathogenic microbes, persistent bacteria that have changed their virulence or new diagnostic techniques now allow their recognition? Or, have they found a new possibility of transmission due to ecological, social or cultural changes? The present Editorial analyses the geographical distribution, features and host factors that favor infections by Helicobacter pylorii, Enterohemorrhagic E. Coli, invasive Streptococcus pyogenes and Borrelia Burgdorferi. The surveillance and care of infections caused by emergent germs requires laboratory learning programs as those established in the United States...

Atoms that are chemically identical but that differed slightly in weight due to the number of nuclear neutrons are called isotopes stables, meaning that do not degrade spontaneously. Mass spectrometry is the analytical technique to evaluate the enrichment on these isotopes with a variety of applications in the clinical diagnosis of pathological processes and the quantitation of metabolic events such as bacterial growth (Helicobacter pylorii), Phenylketonuria, lactose intolerance, liver and pancreatic function, body composition and energy expenditure, cholesterogenesis, glucose utilization, etc...
