Background:
Although a number of studies on the polymorphisms in COX1 and COX2 genes in association with risks for a number of cancers have been conducted, their relation to gastric cancer has not been well studied.
Patients And Methods:
Genotypes of several variants in both COX1 (Ex7+31 C>A and Ex10-4 G>A) and COX2 (-765 G>C, Ex10+837 T>C, Ex10-90 C>T, IVS5-275 T>G, and IVS7+111 T>C) were identified by TaqMan assays in 305 gastric cancer cases and 427 age- and gender-matched controls in a high-risk Polish population. Odds ratios for gastric cancer and 95% confidence intervals from unconditional logistic regression models were used to evaluate relative risks.
Results:
We found no statistically significant evidence that the polymorphisms tested in COX1 and COX2 are associated with gastric cancer risk.
Conclusion:
These results suggest that the polymorphisms examined in COX1 and COX2 do not affect the risk of gastric cancer.

Gastritis II: Pathophysiology
Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...
