When hematochezia becomes a red herring

Acta Gastro Enterologica Belgica, 2021
An 81-year-old male patient presented on the emergency ward for hematochezia, without any other complaints. Rectosigmoidoscopy showed a predominant patchy inflammation of the mucosa with several bluish blebs (submucosal hemorrhage) and small ulcerations. (Figure 1A). Subsequent elective colonoscopy (1) revealed multiple submucosal hematomas and mucosal

Resolvin D5 Inhibits CXCL8 Expression in Colonic Epithelial Cells Through Activating GPR101 to Impede Neutrophil Recruitment and Consequently Alleviate Ulcerative Colitis

Advanced Science, EarlyView.
RvD5 effectively alleviates UC by inhibiting STAT1 signaling to reduce CXCL8 expression in colonic epithelial cells via activation of GPR101, which subsequently decreases the infiltration of neutrophils in the colonic mucosal epithelium. Epimedin A1, a natural allosteric inhibitor of 5‐LOX, demonstrates potential as a therapeutic agent for UC by ...

Targeting Peptostreptococcus anaerobius with an Iron‐Based Nanozyme Reverses Ferroptosis Resistance and Enhances Antitumor Immunity in Colorectal Cancer

Advanced Science, EarlyView.
An iron‐based nanozyme selectively eliminates intratumoral P. anaerobius while catalytically generating ROS to induce ferroptosis, synergistically suppressing colorectal cancer growth and activating anti‐tumor immunity through immunogenic cell death. ABSTRACT The intratumoral microbiota is a critical determinant of therapeutic outcomes in colorectal ...

Constraint of Lignin–Carbohydrate Complex Orchestrated on Polyphenol in Oil–Water Interface Targeting Ulcerative Colitis Therapy

Advanced Science, EarlyView.
This study constructed the W1/O/W2 emulsion–based targeted therapy delivery system for ulcerative colitis (UC) utilizing LCC as surfactant for the first time. This multifunctional emulsion offered certain therapeutic advantages for UC, including targeted colonic delivery of active compounds, synergistic modulation of gut microbiota through combined ...
