RHOJ derived peptide promotes chemosensitivity by inhibiting glutamine metabolism in gastric cancer

Journal of Translational Medicine
Background Chemoresistance is a cause of chemotherapy failure in gastric cancer (GC) treatment. Recent studies have shown that the dysregulation of glutamine metabolism plays a pivotal role in promoting chemoresistance.

Miniaturized Magnetic Tip Design for Endoluminal Vine Robot Navigation

Advanced Robotics Research, EarlyView.
A magnetic tip mount is designed for a miniaturized 7 mm soft‐growing vine robot to enable wireless magnetic steering and onboard imaging, while preserving a 3 mm working channel. The internal–external ring magnets design balances magnetic attachment with low eversion pressure. Experiments demonstrate ±90° steering, 34 mm bending radius, and successful
