Gastric Foveolar‐Type Hyperplastic Polyp of the Duodenum With GNAS and KRAS Mutations: A Potential Precursor to Neoplasia

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT We report a gastric foveolar‐type hyperplastic polyp of the duodenum harboring mutations in the GNAS and KRAS genes. The lesion was incidentally detected during a routine upper gastrointestinal endoscopy in a man in his 50s. It appeared as a 10‐mm elevated lesion located at the superior duodenal angle.

Zinc‐Coordinated Trienzyme Nanogel Cascade Therapy for Accelerated Post‐Pancreatectomy Cutaneous Wound Healing

Advanced Materials, Volume 37, Issue 50, December 17, 2025.
A zinc‐coordinated nanogel assembly is reported that co‐delivers three enzymes to regulate glucose, oxidative stress, and oxygen levels. This system mimics natural enzyme cascades to reprogram the wound environment after pancreatectomy. In a post‐pancreatectomy mouse model, it accelerates healing by reducing infection, promoting blood vessel growth ...

Intraductal Papillary Neoplasms of the Bile Duct

International Journal of Hepatology, 2014
Intraductal papillary neoplasm of the bile duct (IPNB) is a rare variant of bile duct tumors characterized by papillary growth within the bile duct lumen and is regarded as a biliary counterpart of intraductal papillary mucinous neoplasm of the pancreas.

From Gene to Enzyme: Multidimensional Decoding of the GGT Molecular Family and Its Clinical Tumor Diagnosis

Cancer Medicine, Volume 14, Issue 23, December 2025.
ABSTRACT Background Gamma‐glutamyltransferase (GGT) is a membrane‐bound enzyme involved in glutathione metabolism and oxidative stress regulation. Although it is traditionally viewed as a liver function marker, emerging evidence suggests that its aberrant expression is closely associated with tumorigenesis, progression, and therapeutic resistance ...

Immunohistochemical Classification of High‐Grade Pancreatic Intraepithelial Neoplasia and Ductal Cancerization in Pancreatic Ductal Adenocarcinoma Using p53, SMAD4, and Mucin Expression

APMIS, Volume 133, Issue 12, December 2025.
ABSTRACT This study was conducted to determine the frequency of high‐grade pancreatic intraepithelial lesions (HG‐PanIN) and the cancerization of ducts (COD), a phenomenon in which invasive cancer spreads within the pancreatic duct, and the differences between mucous profiles in pancreatic ductal adenocarcinoma.
