ABSTRACT Iron is an essential element for biological systems. There is increasing evidence that excess iron supplementation results in the deposition of iron in the duodenum and enhances mucosal injury and cell proliferation in the colon and cecum. In the present study we examined whether chronic exposure to high levels of iron fortification affects the functional integrity of the small intestine, especially the activities of various brush border enzymes. Wistar rats were fed iron 29 mg/kg body weight (or 6.58 mg/kg Fe) daily in the form of FeSO(4).7H(2)O for 39 days. The activities of brush border alkaline phosphatase (AP) (p < 0.001), sucrase (p < 0.01), maltase (p < 0.05), lactase (p < 0.05), and trehalase (p < 0.001) were reduced in purified membranes in iron-fed animals compared to controls. However, the activities of leucine amino peptidase (LAP) and gamma-glutamyl transpeptidase (gamma-GTP) were unaffected under these conditions. Analysis of alkaline phosphatase activity across the crypt-villus unit revealed a significant decrease (p < 0.05) all across the crypt-villus length, while sucrase activity was reduced (p < 0.01) only in the midvillus axis in iron-exposed animals. Kinetic studies showed a decrease in V(max) of AP from 1.11 to 0.83 units/mg protein and for sucrase from 0.77 to 0.43 units/mg protein in iron-fed rats, with no change in the apparent K(m) of the enzymes (AP, 8 mM; sucrase, 10 mM). Western blot analysis corroborated these findings. These results indicate that chronic iron exposure alters the activities of brush border enzymes, resulting in intestinal dysfunctions.

Background: Chemotherapy-induced mucositis (CIM) significantly impacts quality of life and reduces survival in patients treated with specific chemotherapeutic agents. However, effective clinical treatments for CIM remain limited. Intravenous immunoglobulin (IVIg), a therapeutic derived from pooled human plasma, is widely used to treat inflammatory diseases.

The intestinal mucosal barrier is a dynamic system that allows nutrient uptake, stimulates healthy microbe-host interactions, and prevents invasion by pathogens. The mucosa consists of epithelial cells connected by cellular junctions that regulate the passage of nutrients covered by a mucus layer that plays an important role in host-microbiome interactions. Mimicking the intestinal mucosa for assays, particularly the generation of a mucus layer, has proven to be challenging.

Objective: To explore the protective effect and mechanism of acetate on sepsis-induced acute kidney injury (AKI) in rats.
Methods: Male Sprague-Dawley (SD) rats were divided into sham operation group (Sham group), sepsis group caused by cecal ligation and puncture (CLP group), and acetate pretreatment group [NaA group, gavage sodium acetate (NaA) 300 mg/kg twice a day for 7 consecutive days before CLP] using a random number table method, with 7 rats in each group. The blood was taken from the main abdominal artery 24 hours after modeling, and renal tissue was collected from the rats.

Enteropathogenic Escherichia coli (EPEC) causes diarrheal disease. Once ingested, these extracellular pathogens attach to the intestinal epithelial cells of their host, collapse the localized microvilli, and generate actin-rich structures within the host cells that are located beneath the attached bacteria, called "pedestals." Palladin is an actin-associated protein that cross-links and stabilizes actin filaments.

Background And Aims: Studies have shown that improving the intestinal flora can alleviate the progression of liver fibrosis. Cordycepin has shown potential anti-inflammatory and anti-fibrosis effects. In this study, we aimed to investigate the effects of cordycepin on liver fibrosis and how it affects the intestinal flora composition to determine a potentially effective therapeutic approach for liver fibrosis.
