It is common practice for patients to lie on their right side during small bowel barium follow-through examinations. The rationale is that this speeds up transit time and improves diagnostic usefulness. The results of a randomized, prospective study of 105 patients are presented. There was no significant difference in either transit time or diagnostic usefulness when the examination was carried out with the patient erect (sitting or ambulant) or when adopting the decubitus position. Abandoning the use of the right side down decubitus position allows a longstanding fiction to be discarded. Furthermore, lack of reclining space has been one factor which may limit the number of patients booked for this examination during a single session. Space for couches and trolleys need no longer be a barrier to the efficient organization of a small bowel screening session.

This study aimed to investigate the protective effects of Lycium barbarum polysaccharide (LBP) on digestive function and intestinal barrier integrity in septic mice, and to explore its underlying mechanisms. A total of 70 healthy male BALB/C mice were randomly assigned into five groups: blank control group (BG, n = 12), control group (CG, n = 12), low-dose group (LDG, n = 12, 200 mg/kg), medium-dose group (MDG, n = 12, 400 mg/kg), and high-dose group (HDG, n = 12, 800 mg/kg). A sepsis model was established by cecal ligation and puncture, followed by treatment with different doses of LBP.

The early microbial colonization of the porcine gut is an important priming factor for gut and immune development. Nevertheless, little is known about the composition of microbes that translocate into the ileo-cecal lymph nodes (ICLN) in the neonatal phase. This study aimed to characterize age- and nutrition-related changes in the metabolically active bacterial and fungal composition of the ICLN in suckling and newly weaned piglets.

Background: Video capsule retention is a complication that can have serious consequences in patients with Crohn's disease (CD). The patency capsule was developed to detect small bowel strictures. The usefulness of patency capsules in patients who do not have evidence of small bowel disease on imaging is uncertain.

Introduction: Hypoalgesic inflammatory bowel disease (IBD) may provide critical insights into human abdominal pain. This condition was previously associated with homozygosity for a polymorphism (rs6795970, A1073V; 1073 val/val ) related to Na v 1.8, a voltage-gated sodium channel preferentially expressed on nociceptors.

(CM), a well-known parasitic fungus that grows on the larvae of , has a variety of pharmacological activities. However, little is known about its safe dosage for animals, including pigs. To explore its effect on intestinal health and evaluate its safe dosage, 30 weaned pigs were randomly allotted to five groups and fed with a basal diet supplemented with different doses of CM for 42 days.
