Paclitaxel/Luteolin Coloaded Dual‐Functional Liposomes for Esophageal Cancer Therapy

Advanced Science, EarlyView.
The authors develop a pH‐sensitive aptamer‐modified liposome (EA2‐PSL‐PTX/LUT) to illustrate a strategy for the precise delivery of combinational chemotherapeutic drugs for esophageal squamous cell carcinoma (ESCC) targeted therapy. EA2‐PSL‐PTX/LUT provides efficient co‐loading, tumor targeting, and controlled release of luteolin and paclitaxel ...

Impact of the COVID‐19 pandemic on colorectal cancer surgery in Japan: Clinical Study Group of Osaka University―A multicenter retrospective study

Annals of Gastroenterological Surgery, Volume 7, Issue 1, Page 121-130, January 2023., 2023
This study aimed to investigate the impact of the COVID‐19 pandemic on colorectal cancer treatment in Japan, that was not fully understood. The COVID‐19 pandemic has reduced the number of colonoscopies and surgeries for colorectal cancer and hindered the detection of asymptomatic early‐stage cancers.

Orally Administered Functional Polyphenol‐Nanozyme‐Armored Probiotics for Enhanced Amelioration of Intestinal Inflammation and Microbiota Dysbiosis

Advanced Science, EarlyView.
This study presents a novel polyphenol‐nanozyme‐armored probiotic system (ECA@EcN) for enhanced treatment of inflammatory bowel disease (IBD). By integrating chitosan‐modified epigallocatechin gallate (EGCG‐CS) with gold nanozymes, the system effectively scavenges ROS, improves probiotic viability, and restores gut microbiota balance.

Defining conversion therapy for esophageal squamous cell carcinoma

Annals of Gastroenterological Surgery, Volume 7, Issue 1, Page 7-9, January 2023., 2023
A multimodality treatment conference with experts from across East Asia was held to establish a consensus for conversion therapy. An agreement was reached that conversion therapy was defined as surgery or chemoradiotherapy (CRT) aiming at cure after initial treatment for tumors that were initially unresectable due to adjacent organ invasion or distant ...

3D Reconstruction of the Human Colon from Capsule Endoscope Video [PDF]

arXiv
As the number of people affected by diseases in the gastrointestinal system is ever-increasing, a higher demand on preventive screening is inevitable. This will significantly increase the workload on gastroenterologists. To help reduce the workload, tools from computer vision may be helpful. In this paper, we investigate the possibility of constructing
