Granulomas are rarely seen in gastric biopsies mostly as an involvement of granulomatous diseases like sarcoidosis, Crohn's disease, infections, neoplasms, and vasculitis. Here, we claim cyanoacrylate as a foreign body type granuloma-causing agent in the stomach after vascular embolisation. We present cyanoacrylate associated gastric changes of three cases: two endoscopic biopsies and one gastr...

helicobacter pylori (h. pylori) infection has been reported in more than half of the world human population. it is associated with gastric inflammation and noticeable infiltration of the immune cells to the stomach mucosa by several cytokines secretion. il-1β, il-18 have been shown to contribute to h. pylori induced gastritis, but the details of inflammation and association of virulence factors...

Helicobacter pylori infection induces gastric inflammation, ulcer, and cancer. H. pylori infection is coordinated in a cascade manner that helps it to colonize in the host. Colonization of bacterium starts by adapting itself to the harsh acidic environment in the stomach. H. pylori has the necessary machinery to neutralise the pH of its surroundings. It also has the ability to sense the pH of i...

Gastric cancer is the 2 leading cause of cancer death worldwide and the 4 most commonly diagnosed cancer worldwide. Helicobacter pylori infection is the major risk factor of gastric cancer, and as such, this bacterium has been classified as a type 1, or definite, carcinogen by the International Agency for Research on Cancer. H. pylori infects the gastric mucosa of more than half of the world's ...

Helicobacter pylori (H. pylori) infection has been reported in more than half of the world human population. It is associated with gastric inflammation and noticeable infiltration of the immune cells to the stomach mucosa by several cytokines secretion. IL-1&beta, IL-18 have been shown to contribute to H. pylori induced gastritis, but the details of inflammation and association of virulence fac...

the features of helicobacter pylori adhesins, their interactions with their host counterparts, regulated and selective gene expressions are amongst the many clever strategies this microorganism undertakes to survive the otherwise sterile gastric milieu. the ingenious crafting of these interactions and the respective host reactions govern, in part, an array of consequences ranging from asymptoma...

Aceylation of cyclooxygenase (COX)-2 by aspirin can trigger the formation of 15(R)-epilipoxin A4, or aspirin-triggered lipoxin (ATL). ATL exerts protective effects in the stomach. Selective COX-2 inhibitors block ATL synthesis and exacerbate aspirin-induced gastric damage. Nitric oxide-releasing aspirins, including NCX-4016, have antiplatelet effects similar to aspirin but do not cause gastric ...

Helicobacter pylori is a Gram-negative bacterium that infects the human gastric mucosa and causes various gastric diseases. H. pylori infection induces the production of inflammatory chemokine CCL20 in gastric mucosa and leads to gastric inflammation. Given that the IL-22/IL-22R axis plays a critical role in the regulation of homeostasis and inflammation of epithelial cells at barrier surfaces,...

Helicobacter pylori (H. pylori) is the strongest known risk factor for gastric carcinogenesis. One cancer-linked locus is the cag pathogenicity island, which translocates components of peptidoglycan into host cells. NOD1 is an intracellular immune receptor that senses peptidoglycan from Gram-negative bacteria and responds by inducing autophagy and activating NF-kB, leading to inflammation-media...

a common belief is that alkali ingestion causes severe esophageal damage and limited gastric injury due to the buffering action of acid. gastric injury has been observed in patients who ingested alkali. gastric outlet obstruction (goo) secondary to caustic ingestion occurs due to fibrosis after resolution of the acute injury and inflammation, most commonly 6 to 12 weeks after initial ingestion....
