Colonic Perineurioma Presenting as a Small Subepithelial Lesion With Distinctive Endoscopic Findings

open access: yesDEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT A 59‐year‐old man with a history of colorectal polypectomy underwent a screening colonoscopy. A 5‐mm reddish lesion was identified in the sigmoid colon. The lesion had a smooth surface without erosion or ulceration and appeared slightly elevated with well‐demarcated margins.

Metal–Metal Cooperative C─F and S─F Bond Cleavage by Low‐Valent Tetracobalt Clusters and Water‐Assisted Fluoroarene Hydrodefluorination

open access: yesAngewandte Chemie, Volume 138, Issue 44, 26 October 2026.
Self‐assembled tetrahedral CoI4 clusters supported by simple bipyridine‐based ligands undergo core rearrangement to cleave S─F and C(sp2)─F bond, forming fluoride‐bridged tetracobalt(II)‐oxo clusters, while exposure of cobalt(I) clusters to molecular oxygen yields cubane‐type cobalt(III) oxo clusters.

Virtual NBI image synthesis using stable diffusion for enhanced recognition of early gastric cancer: a technical validation study

open access: yesAnnals of Medicine
Background Narrow band imaging (NBI) can assist endoscopists in detecting early gastric cancer (EGC) more easily, but its widespread use is hindered by economic cost and technical property rights. We aim to realize the conversion of white light endoscopy

White Globe Appearance Is an Endoscopic Predictor of Metachronous Multiple Gastric Cancers

open access: yesDEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives White globe appearance (WGA) is a small white lesion with a globular shape identified during magnifying endoscopy with narrow‐band imaging. However, the association between WGA and metachronous gastric cancer remains unclear. Methods This study involved patients who underwent endoscopic submucosal dissection (ESD) for first‐episode ...

Somatic Mosaic AXIN2‐associated Colonic Polyposis Predominantly Involving the Proximal Colon: A Case Report

open access: yesDEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Colonic adenomatous polyposis is most commonly caused by germline pathogenic variants in the APC gene; however, recent genetic studies have identified patients without APC mutations. AXIN2‐associated colonic polyposis is a rare condition related to dysregulation of the Wnt/β‐catenin signaling pathway. Most reported cases have involved germline

A novel integrated platform for the identification of surgical margins in oral squamous cell carcinoma: results from a prospective single-institution series

open access: yesBMC Cancer, 2019
Background The optimal surgical margins assessment is capital in oral squamous cell carcinoma (OSCC) management. We evaluated the clinical benefits of integrating intraoperative macroscopic margin (MM) assessment and narrow band imaging (NBI).

Feature‐Based Patterns Associated With Japan NBI Expert Team Type 1 Classification of Serrated Colorectal Lesions: A Post Hoc Decision Tree Analysis

open access: yesDEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives Japan NBI Expert Team (JNET) Type 1 classification is used for optical characterization of colorectal lesions with magnifying NBI, but reported Type 1‐related findings may differ between readers when assessing serrated lesions. This small‐scale post hoc reader‐based study explored reported feature‐classification patterns associated ...
