Clinical management of endoscopically resected pT1 colorectal cancer [PDF]

, 2018
Background Implementation of colorectal cancer (CRC) screening programs increases endoscopic resection of polyps with early invasive CRC (pT1). Risk of lymph node metastasis often leads to additional surgery, but despite guidelines, correct management ...

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

A Peripheral Mechanism of Depression: Disturbed Intestinal Epithelial Per2 Gene Expression Causes Depressive Behaviors in Mice with Circadian Rhythm Disruption via Gut Barrier Damage and Microbiota Dysbiosis

Advanced Science, EarlyView.
Circardian rhythm disorder (CRD) causes abnormal expression of intestinal Period 2 (Per2) gene, which compromising intestinal barrier integrity and altering the gut microenvironment. Microbiota dysbiosis and aberrant metabolites production drive central inflammation, impair neurogenesis, and promote functional deficits, ultimately facilitating the ...
