A Convoy of Magnetic Millirobots Transports Endoscopic Instruments for Minimally‐Invasive Surgery
Advanced Science, EarlyView.The first electrocautery procedure performed by a team of millirobots (TrainBots) is presented. Enhanced with optimized feet, millirobots form a convoy to facilitate the collaborative transportation of wires and catheters through biological lumens, e.g. bile ducts. It opens up the possibility of using a team of mini‐robots in future endoscopic surgery.

Advanced Science, EarlyView.The splicing factor PTBP3 promotes COX11 exon skipping, allowing gastric cancer organoids to evade cuproptosis. Antisense oligonucleotide drugs targeting PTBP3‐mediated COX11 alternative splicing, in combination with copper ionophores, promote cuproptosis in organoids, thereby providing a therapeutic approach for gastric cancer peritoneal metastasis ...

Neuroendocrine Carcinoma and Intracystic Papillary Neoplasm: A Rare Association in the Gallbladder [PDF]
GE - Portuguese Journal of Gastroenterology, 2019 Neuroendocrine carcinoma of the gallbladder is a very rare neoplasia comprising only 0.2% of all the gastrointestinal neuroendocrine tumors. We present the case of an 85-year-old male with nonspecific gastrointestinal symptoms, progressive weight loss, and deterioration in the preceding 15 days.
