Helicobacter pylori is a microaerophilic bacterium associated with gastric inflammation and peptic ulcers. Knowledge of how pathogenic organisms produce energy is important from a therapeutic point of view. We found d-amino acid dehydrogenase-mediated electron transport from d-proline or d-alanine
The combination of immunodeficiency, inflammatory process and nutritional status that is characteristic of infective and food-borne illness is more evident in chronic diet- and environment-influenced chronic diseases such as diabetes, obesity, cardiovascular disease, cancer, arthritis and
Disaminoacidemia was shown to be of much higher degree in involvement of the intestinal hepatobiliary system in patients with ulcer disease, in addition, in elderly and old people the content of free amino acids (AA) in the blood serum is significantly reduced. Present in the least amounts are
Helicobacter pylori antigen was prepared from an isolate from a patient with a duodenal ulcer. Serum samples were obtained from culture-positive H. pylori infected patients with duodenal ulcers, gastric ulcers and gastritis (n=30). As controls, three kinds of sera without detectable H. pylori IgG
Helicobacter pylori can utilise amino acids as the sole carbon energy source. The present study demonstrated that H. pylori grown in continuous culture in a defined medium containing glucose and amino acids utilised alanine, arginine, asparagine, aspartate, glutamine, glutamate, proline and serine.
Helicobacter pylori is a microaerophilic bacterium, associated with gastric inflammation and peptic ulcers. D-Amino acid dehydrogenase is a flavoenzyme that digests free neutral D-amino acids yielding corresponding 2-oxo acids and hydrogen. We sequenced the H. pylori NCTC 11637 D-amino acid
The concentrations of free D- and L-amino acids were determined in the gastric juice from four groups: patients suffering from early gastric carcinoma with or without Helicobacter pylori infection, and patients without carcinoma but with peptic ulcers, duodenal ulcers or chronic gastritis with or
The zinc-dependent matrix metalloproteinases (MMPs) are key enzymes associated with extracellular matrix (ECM) remodeling; they play critical roles under both physiological and pathological conditions. MMP-9 activity is linked to many pathological processes, including rheumatoid arthritis,
H. pylori is a gram-negative bacterium associated with gastric inflammation and peptic ulcer and considered a risk factor for gastric cancer in its natural habitat. However, the energy metabolism of H. pylori in the stomach remains to be clarified. H. pylori shows rather high respiratory activity
Ulcer-associated dyspepsia is caused by infection with Helicobacter pylori. H. pylori is linked to a majority of peptic ulcers. Antibiotic treatment does not always inhibit or kill H. pylori with potential for antibiotic resistance. The objective of this study was to determine the potential for
Tea polyphenolics such as catechins are known to have the potential to inhibit many bacterial pathogens. Helicobacter pylori has been identified as an etiologic agent in the development of gastric ulcer, peptic ulcer, gastritis, and many other stomach-related diseases. In this study, we investigated
The DNA sequence of the two human mucin genes MUC2 and MUC6 have not been completely resolved due to the repetitive nature of their central exon coding for Proline, Threonine and Serine rich sequences. The exact nucleotide sequence of these exons has remained unknown for a long time due to
