The oxyntic mucosa of the mouse stomach is lined with a heterogeneous population of cells that form numerous short pits continuous with long tubular glands. Tritiated thymidine radioautography has made it possible to pinpoint the origin of all cell types and to follow the differentiation/migration of different cell lineages along the pit-gland unit. The proliferating multipotent stem cells func...

gastric endoscopy was performed in the 24 persian arab horses from several race training in tehran and tabriz for detection of gastric ulcer. gastric ulcer was evident in 14 persian arab horses (58.3%). ten out of 14 ulcers were in nonglandular region of the stomach. the horses with the history of long term treatment with non-steroidal anti-inflammatory drugs (nsaids) had high prevalence of the...

A randomized controlled trial has started in both Japan and Korea to evaluate the role of gastrectomy in the management of incurable advanced gastric cancer (AGC). Patients with AGC diagnosed as having a single non-curable factor are randomized to gastrectomy plus chemotherapy or chemotherapy alone. Surgeons at 33 specialized centers in Japan and at 15 high-volume hospitals in Korea will recrui...

Each year, ~988,000 new cases of stomach cancer are reported worldwide. Uniformity for the definition of advanced gastric cancer (AGC) is required to ensure the improved management of patients. Various classifications do actually exist for gastric cancer, but the classification determined by lesion depth is extremely important, as it has been shown to correlate with patient prognosis; for examp...

Gastric motility in the Great Horned Owl (Bubo virginianus) has been the subject of few previous studies. A gastroduodenal contraction sequence beginning with the glandular stomach (proventriculus), then the muscular stomach (gizzard), and lastly the duodenum was observed radiographically by Reed and Reed (1928) and Kostuch and Duke (1975). Contractions arise near the isthmus in the muscular st...

introduction: to write a computational program to calculate the average glandular dose in mammography with rh-rh target-filter and also use it as an accurate and fast method of dose calculation founder different situations. materials and methods: in this research, the sobol-wu parameters are used to write a fortran code for glandular dose calculation in rh-rh target-filter mammograms. the code ...

BACKGROUND/AIMS Improvements in the endoscopic evaluation and management of gastric cancer have made it possible to determine the depth of invasion during endoscopic examination. The aim of this study was to elucidate the differences between early gastric cancer (EGC) that resembles advanced gastric cancer (AGC) and AGC that resembles EGC. METHODS We retrieved cases of EGC-like AGC and AGC-li...

INTRODUCTION Measurement of residual gastric volume is a frequent practice in chronic patients, but there is lack of consensus on the convenience of reintroducing or discarding aspirated gastric content (AGC). OBJECTIVE Determine the grade of scientific evidence on the efficacy of two interventions -reintroduction/rejection- of AGC in chronic patients. MATERIAL AND METHODS Systematic review...

Studies have shown that a majority of known human carcinogens also cause cancer in laboratory animals. The converse, however, is not as well established-known animal carcinogens are not equally predictive of human carcinogenicity. A particularly controversial aspect of interspecies extrapolation is application of rodent forestomach tumor data for predicting cancer risk in humans, given that a h...
