The authors studied morphologic changes in gastric lining of patients facing chronic mercuric intoxication. The examinees are former burners at metallurgic plant of Khaidarkansk mercuric enterprise. The patients demonstrated significant destruction of the superficial epithelial cells and the accumulation of Campylobacter piloridis. The parietal and zymogen cells appeared to have depressed functional activities. The cells in gastric antrum had ultrastructure characterized by vacuoles with dense filaments which could be a morphologic marker of mercuric intoxication.

Objective: The gut-brain axis (GBA) is involved in the modulation of multiple physiological activities, and the vagus nerve plays an important role in this process. However, the association between vagus nerve function and nutritional regulation remains unclear. Here, we explored changes in the nutritional status of mice after vagotomy and investigated the underlying mechanisms responsible for these changes.

Objective: This study aimed to explore the predictive value of baseline CT body composition and its early changes on recurrence-free survival (RFS) following radical gastrectomy, while also assessing potential sex-related differences.
Methods: We conducted a retrospective analysis of gastric cancer (GC) patients with confirmed pathology from October 2019 to May 2023. All patients underwent preoperative and postoperative CT scans to assess visceral fat area (VFA), subcutaneous fat area (SFA), skeletal muscle area (SMA), and skeletal muscle density (SMD), along with calculating their respective rates of change.
Evidence for successful gastric perfusion computed tomography with low-radiation dose.

Cooperative Division of Veterinary Sciences, Tokyo University of Agriculture and Technology, Fuchu, Tokyo, Japan.
Objective: To investigate how the blood flow analysis changes by varying the radiation dose of gastric perfusion CT (PCT) and to prove that a low-radiation dose of PCT is feasible.
Methods: 5 Beagle dogs were used in a crossover study with 6 groups of varying radiation doses. Iodixanol was IV administered at 3.
Changes in basic composition and digestive characteristics of pork induced by frozen storage.

College of Food Science, Northeast Agricultural University, Harbin, Heilongjiang, China.
Introduction: Frozen pork can reduce the quality of the meat and alter the digestibility and bioavailability of meat proteins in the human body. In this study, we investigated the changes in the basic composition during frozen storage and their effects on the structural properties of digestion products after protein digestion.
Methods: The impacts of frozen storage at different temperatures (-8, -18, -25, and -40°C) and for different times (1, 3, 6, 9, and 12 months) on the basic components and digestive characteristics of pork were evaluated.
Macranthoside B Suppresses the Growth of Adenocarcinoma of Esophagogastric Junction by Regulating Iron Homeostasis and Ferroptosis through NRF2 Inhibition.

Background: Macranthoside B (MB) is a saponin compound extracted from hon-eysuckle that has been reported to exhibit significant medicinal values, particularly anti-tumor activities. This study aimed to evaluate the anticancer efficacy of MB in treating adenocarci-noma of the esophagogastric junction (AEG) and elucidate its underlying mechanisms.
Methods: Three AEG cell lines and normal gastric epithelial cells were used to assess the an-ticancer activity of MB in vitro.
