Let G be a finite graph on [n] = {1, 2,…, n}, X a 2 × n matrix of indeterminates over a field K,
and S = K[X] a polynomial ring over K. In this article, we study about ideals I G of S generated …

We investigated the relationship between the diversity of Helicobacter pylori CagA protein
and clinical outcome. The cagA gene was sequenced in 115 clinical isolates. The binding …

Colonization of the stomach mucosa by Helicobacter pylori is a major cause of acute and
chronic gastric pathologies in humans. Several H. pylori virulence genes that may play a role in …

Genetic diversity within the cag pathogenicity island (PAI) of Helicobacter pylori may have a
modifying effect on the pathogenic potential of the infecting strain. The genetic structure of …

Recent experiments have indicated that CagA of Helicobacter pylori is injected into epithelial
cells via the type IV secretion system and undergoes tyrosine phosphorylation in cells and …

The severity of Helicobacter pylori-related disease is correlated with the presence of a cag
pathogenicity island (PAI). Genetic diversity within the cag PAI may have a modifying effect on …

AIM To investigate the efficacy and safety of emergency endoscopic retrograde
cholangiopancreatography (ERCP) in elderly patients with acute cholangitis. METHODS From June …

A novel cardio-excitatory peptide was purified from the hearts ofAplysia kurodai.The peptide
was a tripeptide containing ad-amino acid residue in the second position, Asn-d-Trp-Phe-…

The incidence of gastric cancer is higher in men than women. Epidemiological studies
suggest that female hormones reduce gastric cancer risk. We examined the effect of ovarian-…

Arachidonic acid 5-lipoxygenase (5-LOX), an enzyme that synthesizes leukotrienes (LTs), is
involved in cancer development including proliferation, invasion, metastasis and drug …
