Helicobacter pylori cag-Pathogenicity island-dependent early immunological response triggers later precancerous gastric changes in Mongolian gerbils [PDF]

, 2009
Infection with Helicobacter pylori, carrying a functional cag type IV secretion system (cag-T4SS) to inject the Cytotoxin associated antigen (CagA) into gastric cells, is associated with an increased risk for severe gastric diseases in humans.

Treatment of gastric precancerous lesions with Weiansan

World Journal of Gastroenterology, 2006
To observe the curative effect of Weiansan (WAS) on gastric precancerous lesions (GPL) and H pylori elimination.Seventy-six patients with GPL were randomly divided into two groups: WAS group (n = 42) and Weifuchun (WFC) group (n = 34). The patients in the WAS group were administered 5 g WAS 3 times a day, and the patients in the WFC group took WFC (4 ...

17Beta-estradiol modulates gastroduodenal preneoplastic alterations in rats exposed to the carcinogen N-methyl-N'-nitro-nitrosoguanidine [PDF]

, 1999
Gastric cancers are a significant cause of morbidity worldwide. Epidemiological studies and animal models show that males have higher incidences of gastric cancers compared with females, suggesting that sex hormones may modulate gastric cancer risk.

Discrimination between Precancerous Gastric Lesions and Gastritis Using a Gastric Cancer Risk Stratification Model [PDF]

, 2023
Background: Seropositivity to certain Helicobacter pylori proteins may affect development of gastric lesions that could become cancerous. Previously, we developed a model of gastric cancer risk including gender, age, HP0305 seropositivity, HP1564 sero ...

Enhanced Classification of Gastric Lesions and Early Gastric Cancer Diagnosis in Gastroscopy Using Multi-Filter AutoAugment

IEEE Access, 2023
Gastric cancer is high-risk cancer in terms of both incidence and mortality. However, if it is diagnosed early, there is a high chance of survival. Therefore, an early diagnosis of gastric cancer and precancerous lesions is very important. Gastroscopy is
