High doses of vitamin A exerted no significant effect of the ability of the rat digestive system to adapt to food. The A hypervitaminosis increased the activity of sucrase and eliminated the ability to regulate the activity of this enzyme by the duodenum in the chicken small intestine.

Gut mucosal immunity of teleost is mainly governed by mucosa-associated lymphoid tissues (MALT) and indigenous microbiota on mucosal surfaces of gut tract, which can confer protection against pathogenic invasion. However, the probiotic features of bacterial isolates from gut tract of triploid cyprinid fish (TCF) were largely unclear. In this study, Lysinibacillus and Enterobacter strains were isolated for probiotic identification.

We report the case of a 68-year-old female patient who had a gastrointestinal stromal tumor involving muscularis propria of the gastric body that was removed through submucosal tunneling endoscopic resection, with favorable follow-up after 5 years, with no signs of recurrence.

We report the case of an elderly patient with progressive dysphagia to solids and later to liquids, and weight loss. The patient underwent an upper endoscopy, which showed multiple stenoses and trachealization. Biopsies were taken and a diagnosis of lymphocytic esophagitis was made.

Objectives: Pancreatic duct leaks can cause ascites, and fluid amylase can be used as a marker to suggest pancreatic duct leak; however, there is no reference parameter or cutoff value for diagnosis. We assessed whether a novel ratio of ascitic fluid to serum amylase can reliably predict pancreatic leaks and need for endoscopic retrograde cholangiopancreatography (ERCP).
Materials And Methods: Patients who had fluid amylase from ascitic fluid and serum amylase within one week of confirmed pancreatic leaks via ERCP were included along with appropriate medical and surgical controls.

Quiescent pancreatic stellate cells (PSCs) represent only a very low proportion of the pancreatic tissue, but their activation leads to stroma remodeling and fibrosis associated with pathologies such as chronic pancreatitis and pancreatic ductal adenocarcinoma (PDAC). PSC activation can be induced by various stresses, including acidosis, growth factors (PDGF, TGFβ), hypoxia, high pressure, or intercellular communication with pancreatic cancer cells. Activated PSC targeting represents a promising therapeutic strategy, but little is known regarding the molecular mechanisms underlying the activation of PSCs.
