Gastric ulcers are erupted when there is an disproportion between the digestive juices generated by the stomach and the diverse factors that defend the mucosal lining of the stomach. Acute gastric problem reduces quickly but Chronic gastric problems lead to ulcers. Nine out of ten Peptic ulcer disease(PUD) or peptic ulcer or stomach ulcer (Gastric and duodenal ulcers) are sore on the inner lining of stomach or deodenum and caused by an infection from the bacterium H. pylori and they are liable to reappear if left untreated. An ulcer in the stomach is called as a gastric ulcer, an ulcer in the duodenum is known as a duodenal ulcer, and a peptic ulcer of the esophagus is an esophageal ulcer. Peptic ulcer disease is suspect in patients with epigastic distress and pain. Peptic ulcers are usually caused by either Helicobacter pylori (H. pylori) bacteria or non-steroidal anti-inflammatory drugs such as Aspirin, Ibuprofen or other NSAIDs.
Recently the diabetes mellitus has been known as one of the main cause of upper gastrointestinal symptoms. Since high prevalence of Helicobacter Pylori in diabetic patients has been reported. The aim of this study was to evaluate the relationship between the level of gastric juice Nitric Oxide, Oxidative Stress and Hyperglycemic Control in diabetic H. Pylori infected patients. In patients with metabolically uncontrolled diabetes mellitus the prevalence of H. Pylori infection is high and the bacteria colonization occurs at the antrum of stomach. After eradication therapy of H. Pylori the control of the glyceamia will be useful. Increased levels of HbA1C in the case group in comparison with those in the uninfected subjects confirm the finding. On the other hand the treatment of the H. Pylori infection improves the level of NO° in the gastric juice and reduces cellular damage resulting from acute oxidative stress produced by reaction between superoxide radicals of H. Pylori and NO° of the gastric juice.
High Quality Content by WIKIPEDIA articles! A flagellum (pronounced /fl d l m/, plural: flagella) is a tail-like projection that protrudes from the cell body of certain prokaryotic and eukaryotic cells, and functions in locomotion. There are some notable differences between prokaryotic and eukaryotic flagella, such as protein composition, structure, and mechanism of propulsion. An example of a flagellated bacterium is the ulcer-causing Helicobacter pylori, which uses multiple flagella to propel itself through the mucus lining to reach the stomach epithelium. An example of a eukaryotic flagellated cell is the sperm cell, which uses its flagellum to propel itself through the female reproductive tract. Eukaryotic flagella are structurally identical to eukaryotic cilia, although distinctions are sometimes made according to function and/or length.
Peptic ulcer disease (encompassing gastric ulcer and duodenal ulcer) disease affects a large portion of the world population. This occurs due to an imbalance between offensive and defensive factors. Helicobacter pylori infection is recognized as the leading cause of ulcer in the world, particularly in non developed countries, it comes under offensive factors and other agents such as alcohol and non steroidal anti-inflammatory drugs gain importance in developed countries comes under defensive factors. Nowadays the main line of approach in the treatment of peptic ulceration is the eradication of H. pylori infection. A large number of anti-ulcer drugs, including antibiotics, proton pump inhibitors and H2 receptor antagonists are available for the treatment of peptic ulcer disease, but clinical evaluations of these drugs have shown incidence of relapse, side effects, drug interactions and rebound hyper secretion following drug withdrawal which leads to high ulcer relapse rate. This has been the rationale for the development of new anti-ulcer drugs and thus search for novel molecules has been extended from plant sources that can offer better protection and have better safety profile.
As someone who has spent nearly half his life wondering about the relationship between Helicobacter and gastric cancer, I find this textbook on the subject exciting and timely. In fact, I am not aware of any other volume that has been able to distil so much new knowledge into such a comprehensive account of a poorly understood field. Taking my own view, as a scientist placed in the middle of the spectrum between basic science and clinical medicine, I can see that the editors, Jim Fox, Andy Giraud, and Timothy Wang, provide a broad mix of expertise, which ensures that the subject is treated with the right balance. From clinicopathologic observations in humans, to epidemiology, through animal models, to molecular and cell biology, this team has hit the mark for most readers. Fox is a well-known leader in animal models with broad expertise. He pioneered the field with observations on Helicobacter species in animals, from the time when only one spiral gastric bac- rium was known, "Campylobacter pyloridis. " Fox partners with Wang, whose team recently announced a dramatic advance in the field of carcinogenesis-the obser- tion that bone marrow-derived stem cells participate in the changes that become cancer. To this nice mix has been added Andy Giraud from my own country, who brings to the table some remarkable genetic models of gastric cancer based on alterations in the gp130/stat3-signaling pathway.
The central role of RNA in many cellular processes has created a high interest in the specific tasks RNA molecules and protein: RNA complexes perform in a cell. In this publication up-to-date experimental methods and protein:RNA interaction protocols were used to identify the native RNA binding motive and to characterize the key role of the protein ribosomal binding factor A(RbfA). To gain insights into the binding mode of RbfA toits target RNA, two RbfA constructs from Thermotoga maritima and Helicobacter pylori were employed. Comparison of the RbfA proteins with the published homologous structure from Escherichia coli, led to studies concerning the structural attributes between proteins from thermophilic and mesophilic systems. The different chapters detail the biophysical and biochemical methods used to investigatethe protein and protein: RNA structures and their function and the advances in understanding the biological processes in which the RbfA protein is involved in.
This book is about the study of association between Helicobacter Pylori (H. pylori) and Chronic Obstructive Pulmonary Disease (COPD). In past years, many studies have been carried out to understand the complex relationship between H. pylori infection and COPD. Few researches have been successful in showing the epidemiologic and serologic evidence for relationship between these two phenomenon. In our study, we aimed to investigate the seroprevalence of Helicobacter pylori in patients with COPD and to determine whether there is an association between H. pylori infection and COPD. The results from our study suggest that there is higher prevalence of H. pylori seropositivity in COPD patients than in non-COPD patients and that HP infection has a positive correlation with the severity of COPD showing the prevalence of HP infection increases with the severeness of COPD. But we were not able to find out the reason for H. pylori infection being related to COPD since our study was carried out in a very small scale and short period of time. To understand the complex relationship between H. pylori infection and COPD, we look forward for a better technical support and a bigger study group.
