Redox‐Programmed Activation of a Dual‐Modal Probe for High‐Fidelity Tumor Delineation and Image‐Guided Surgery

Advanced Science, Volume 13, Issue 16, 18 March 2026.
This study presents a glutathione (GSH)‐activatable dual‐modality probe (GAP9) with a redox‐tuned activation window for precise tumor detection. It remains quenched (“OFF”) in normal tissue yet activates specifically in tumors for T1‐weighted magnetic resonance imaging (MRI) preoperative mapping and near‐infrared II (NIR‐II) fluorescence intraoperative

SAGE: Spatially Aware Gene Selection and Dual‐View Embedding Fusion for Domain Identification in Spatial Transcriptomics

Advanced Science, Volume 13, Issue 16, 18 March 2026.
SAGE is a unified framework for spatial domain identification in spatial transcriptomics that jointly models tissue architecture and gene programs. Topic‐driven gene selection (NMF plus classifier‐based scoring) highlights spatially informative genes, while dual‐view graph embedding fuses local expression and non‐local functional relations.

Systematic Review and Meta‐Analysis of Short‐ and Long‐Term Outcomes Following Natural Orifice Specimen Extraction for Colon Cancer

Annals of Gastroenterological Surgery, Volume 10, Issue 2, Page 336-347, March 2026.
ABSTRACT Background Natural orifice specimen extraction (NOSE) in colon cancer surgery raises concerns about intra‐abdominal infection, peritoneal seeding, and local recurrence due to possible tumor cell implantation. This systematic review and meta‐analysis compares complete intracorporeal resection with NOSE versus conventional laparoscopic colon ...

Characteristics and Prognosis of Early‐Onset vs. Late‐Onset Colon Cancer: A Propensity Score Matching Analysis Based on Histology

Cancer Medicine, Volume 15, Issue 3, March 2026.
ABSTRACT Objectives The prognostic value of age at diagnosis in colon cancer is poorly understood. This study evaluated the influence of age at diagnosis and histologic subtype on colon cancer prognosis using data from 180,804 patients in the SEER database.
