Hypergraph-Transformer (HGT) for Interactive Event Prediction in Laparoscopic and Robotic Surgery [PDF]

arXiv
Understanding and anticipating intraoperative events and actions is critical for intraoperative assistance and decision-making during minimally invasive surgery. Automated prediction of events, actions, and the following consequences is addressed through various computational approaches with the objective of augmenting surgeons' perception and decision-

Reversal of Stress‐Induced PIEZO1 Elevation with Mechanically Adapted Epicardial Patch for Myocardial Infarction Treatment

Advanced Science, EarlyView.
This work identifies fine‐tuning the expression of PIEZO1 as a critical molecular mechanism underlying the treatment of myocardial infarction by mechanically adapted cardiac patches, which can support the clinical translation of cardiac patch devices.

A Hybrid Model and Learning-Based Force Estimation Framework for Surgical Robots [PDF]

arXiv
Haptic feedback to the surgeon during robotic surgery would enable safer and more immersive surgeries but estimating tissue interaction forces at the tips of robotically controlled surgical instruments has proven challenging. Few existing surgical robots can measure interaction forces directly and the additional sensor may limit the life of instruments.

CCDC80 Protects against Aortic Dissection and Rupture by Maintaining the Contractile Smooth Muscle Cell Phenotype

Advanced Science, EarlyView.
Aortic dissection (AD) is accompanied by a decrease in CCDC80 in vascular smooth muscle cells (VSMCs). CCDC80 can interact with JAK2, and VSMC‐specific CCDC80 deficiency accelerates the progression of AD by activating the JAK2/STAT3 pathway involved in regulating the phenotype switching and function of VSMCs.

Novel Quaternary Ammonium Salt‐Linked STING Agonist Antibody‐Drug Conjugate: Synergistic Activation of Tumor Immunity with Mitigated Off‐Target Toxicity

Advanced Science, EarlyView.
Novel quaternary ammonium salt‐linked STING agonist ADC demonstrates high potency, stability, enhanced solubility, and reduced off‐target toxicity, potently activating the STING pathway in the tumor microenvironment through the synergistic action of the Fab and Fc regions of antibodies (activity switch‐on) while exhibiting ≈20 fold lower activity in ...

Mechanical Stress Induced NOX2 Promotes Endothelial Dysfunction in Ventilator‐Induced Lung Injury: Potential Treatment with Quercetin

Advanced Science, EarlyView.
Abnormal mechanical stretch induced by mechanical ventilation (MV) disrupts endothelial junctions via the NOX2/ROS/CaMKII/ERK1/2 axis both in human aortic endothelial cells (HAECs) in vitro and in ventilator‐induced lung injury (VILI) in mice. Quercetin, an antioxidant predicted to bind to NOX2, can effectively prevent mechanical stretch‐induced ...

Dense 3D Reconstruction Through Lidar: A Comparative Study on Ex-vivo Porcine Tissue [PDF]

arXiv
New sensing technologies and more advanced processing algorithms are transforming computer-integrated surgery. While researchers are actively investigating depth sensing and 3D reconstruction for vision-based surgical assistance, it remains difficult to achieve real-time, accurate, and robust 3D representations of the abdominal cavity for minimally ...
