hsa_circ_0015388 Reduces Macrophage Derived Reactive Oxygen Species in Crohn's Disease.

Background: Crohn's disease (CD) is a refractory inflammatory bowel disease with an unclear etiology. CircularRNA (circRNA) has been highlighted as a novel class of functional noncoding RNAs associated with the pathogenesis of various diseases. However, the functions of circRNA in CD remain unclear.

Anti-integrin αvβ6 antibody as a biomarker for diagnosing ulcerative colitis: a nationwide multicenter validation study.

Background: A serum biomarker for diagnosing ulcerative colitis (UC) remains to be established. Although we recently reported an anti-integrin αvβ6 antibody (V6 Ab) for diagnosing UC with high sensitivity and specificity, no large-scale validation study exists. This study aimed to validate the diagnostic value of V6 Ab for UC using a nationwide multicenter cohort study.

Unresectable Ulcerative Colitis Associated Colon Cancer in a Young Japanese Patient: A Case Report.

We herein present the case of a 30-year-old Japanese male patient with ulcerative colitis (UC) who was admitted to our hospital because of significant ascites. Upon evaluation, the patient was diagnosed with unresectable UC-associated cancer (UCAC), localized in the transverse colon. Using gene profiling of the tumor tissue, anti-epidermal growth factor receptor (EGFR) antibody combination chemotherapy was selected.

The white ring sign is useful for differentiating between fundic gland polyps and gastric adenocarcinoma of the fundic gland type.

Gastric adenocarcinoma of the fundic gland type (GA-FG) is characterized by an elevated lesion with vessel dilation exhibiting branching architecture (DVBA). However, this feature is also found in fundic gland polyps (FGPs), posing a challenge in their differentiation. In this study, we aimed to investigate the clinicopathological features of gastric elevated lesions with DVBA and assess the efficacy of the white ring sign (WRS) as a novel marker for distinguishing between FGPs and GA-FGs.
