Stent-based and catheter-based endobiliary radiofrequency ablation for malignant biliary obstruction: an ex-vivo comparative study

Dong‐Sung Won, Yubeen Park, Sohee Lee, Yebin Seo et autres

Endobiliary radiofrequency ablation (RFA) is used as an adjunct therapy to improve local tumor control and stent patency; however, catheter-based RFA may result in non-uniform ablation in curved or tortuous ducts because of incomplete electrode-wall contact. This study compared stent-based electrodes with …

Minimally overlapping technique of bioresorbable scaffolds in a porcine coronary artery model: proof-of-concept study

Ji Won Kim, Dong‐Sung Won, Seung Jin Eo, Song Hee Kim et autres

Overlapping stent placement is a common approach for treating long coronary artery disease, but is associated with increased risks of restenosis and thrombosis. This preliminary study evaluated the efficacy and safety of a minimally overlapping technique using bioresorbable scaffolds (BRSs) compared with …

D2E: Scaling Vision-Action Pretraining on Desktop Data for Transfer to Embodied AI

Jung Jae-Yoon, Minchan Kim, Minyeong Kim, Yongjun Cho et autres

Large language models leverage internet-scale text data, yet embodied AI remains constrained by the prohibitive costs of physical trajectory collection. Desktop environments -- particularly gaming -- offer a compelling alternative: they provide rich sensorimotor interactions at scale while maintaining the structured observation-action …

Detachable Microneedle Patch for Local Delivery of TGF‑β Inhibitor to Suppress Scar Formation

Yubeen Park, Suhyang Lee, Seung Jin Eo, Song Hee Kim et autres

Abstract Severe wounds often lead to delayed healing and fibrotic scar formation, primarily driven by dysregulated transforming growth factor beta (TGF-β) signaling, which causes excessive collagen accumulation. Current treatments face limitations, including poor drug delivery, systemic side effects, and patient compliance issues. …

Everolimus‐Coated Laser‐Cut Self‐Expandable Metallic Stent Suppresses Stent‐Induced Tissue Hyperplasia in a Rat Gastric Outlet

Yubeen Park, Chae Eun Yun, Dong‐Sung Won, Song Hee Kim et autres

Malignant gastric outlet obstruction is a severe complication of gastrointestinal malignancies, often treated with self‐expandable metallic stents (SEMSs). However, conventional SEMSs are associated with in‐stent restenosis due to granulation tissue formation. This work aims to evaluate the efficacy and safety of everolimus‐coated …
