Background The mucosal layer of the colon contains metabolism-related fluorophores, such as reduced nicotinamide adenine dinucleotide (NADH), which might have the potential to serve as biomarkers for detecting neoplasia. Objective To examine NADH flu

Accurate diagnosis of metastatic lymph nodes (LNs) is essential in choosing appropriate treatment for gastrointestinal carcinoma. Our aim was to evaluate the diagnostic power of 5-aminolevulinic acid (5-ALA) for LN metastasis in mouse rectal cancer.
