Intestinal mucosal injury that develops as a complication of tocilizumab (TCZ) is usually associated with diverticulosis. We herein report a rare case of TCZ-induced intestinal mucosal injury in the absence of diverticulosis. A 74-year-old woman suffering from rheumatoid arthritis started taking TCZ. Six months later, she complained of hematochezia and abdominal pain. Colonoscopy revealed multiple ulcers spreading from the cecum to the transverse colon but no diverticulosis. These lesions were cured at three months after the discontinuation of TCZ. We should consider TCZ as a risk factor for intestinal mucosal injury, even if patients have no history of intestinal disease associated with diverticulosis.

Vasculature of the small bowel mucosa, with a significant role in nutrient absorption and gut homeostasis, has been suggested to undergo remodeling in various gastrointestinal disorders, including celiac disease. However, due to its spatial organization within the mucosa, conventional 2D histological methods are of limited value in studying the intestinal vasculature reliably. X-ray microtomography (micro-CT) is a promising tool for soft tissue imaging, as it enables digital 3D reconstruction of various tissue samples, including endoscopically obtained small-bowel mucosal biopsies.

Toxoplasmosis is a parasitic disease affecting a significant portion of the global population, whose etiology can be attributed to the protozoan organism Toxoplasma gondii. Despite its public health importance, an efficacious vaccine to prevent human toxoplasmosis remains unavailable. To this end, we designed an experimental toxoplasmosis vaccine using recombinant vaccinia virus vectors (rVacv) expressing the T.

Gastric ulcers often cause postprandial epigastric pain, especially in acute cases. Abnormal motility, with about 50 % of patients having delayed gastric emptying, contributes to ulcer development. Costunolide (COS) and dehydrocostuslactone (DEH), derived from "Mu xiang" herbs, show potential in treating ulcers and regulating gastrointestinal motility.

Necrotizing enterocolitis (NEC) is an intestinal inflammatory and necrotic disease seen in premature infants, and remains the leading cause of death resulted from gastrointestinal diseases in premature infants. The specific pathogenesis of NEC is still unclear. In recent years, a lot of studies have reported that Toll-like receptor 4 (TLR4) plays a key role in the pathogenesis of NEC.
