In the antrum the pits are called pyloric glands and contain G cells that regulate the production of hydrochloric acid from parietal cells (Fig. 6.15). Sign in to download full-size image Figure 6.13. The functional regions of the stomach. The parietal cell is the dominant cell type in 80...
Exclusion of the pylorus had very little effect on the pressures developed in body and antrum. The clinical implications of these findings are discussed.doi:10.1136/gut.4.2.174A K ArmitageA. C. B. DeanGutArmitage AK , Dean AC ( 1963 ) Function of the pylorus and pyloric antrum in gastric...
arrays were positioned on the antrum and used to detect significant increases in the velocity (3.3 ± 0.1 mm s-1 vs 7.5 ± 0.6 mm s-1; p<0.01) and amplitude (1.5 ± 0.1 vs 2.5 ± 0.1 mV; p<0.01) of slow wave activity as it passes from the proximal to the prepyloric antrum. ...
Gastric cancer is the fifth most common cancer type. Most patients are diagnosed at advanced stages with poor prognosis. A non-invasive assay for the detection of early-stage gastric cancer is highly desirable for reducing associated mortality. We collec
1e and f). The immunoreaction of the APOBEC2-positive cells in the body of the stomach and antrum was comparatively stronger and lighter (Fig. 2). Representative immunohistochemistry images of APOBEC2 staining in gastric cancer tissues as Fig. 2. Fig. 2 Representative immunohistochemistry images ...
This type was localized mainly in the antrum (75%) and in more than 60% of the cases it corresponded to Laurén’s intestinal subtype. MSI subtype was associated with the presence of hypermutation, with mutations in the genes KRAS (23.3%), ALK (16.3%) and ARID1A (44.2%), involved in...
In PrPD, the stomach was divided proximally just near the pyloric ring to preserve the antrum and almost the whole stomach. The gallbladder, pancreatic head with the bile duct, duodenum, and the first jejunal loop were removed, except for the first portion of the duodenum, in PpPD. In all...
HPs are most common in the antrum (60%), but may arise throughout the stomach, including the cardia and gastroesophageal area. 30, 33 Microscopic Features HPs have a polypoid form and show elongated, branching, and cystically dilated foveolar glands (Fig. 5). The foveolar cells have a ...

(which are more frequent in areas with a lower incidence) have a much poorer prognosis than those with tumors arising in the pyloric antrum (more frequent in areas with a higher incidence), with lower 5-year survival rates and higher operative mortality. In addition, accurate screening for ...
