Advanced Science, EarlyView.Occlusion of tumor blood vessels represents a promising yet challenging approach in cancer treatment. Herein, supramolecularly engineered platelets conjugated with morphology‐transformable nanoparticles is developed for precise tumor embolization. The engineered platelets actively accumulate at tumor sites following induced blood vessel injury.

Attention based CNN-LSTM Network for Pulmonary Embolism Prediction on Chest Computed Tomography Pulmonary Angiograms [PDF]
arXiv, 2021 With more than 60,000 deaths annually in the United States, Pulmonary Embolism (PE) is among the most fatal cardiovascular diseases. It is caused by an artery blockage in the lung; confirming its presence is time-consuming and is prone to over-diagnosis.

Fitting rectangles under vulnerability curves: optimal water flow through plants [PDF]
Mathematical Methods in the Applied Sciences, 41 (2018)
pp.7949-7957, 2019 We study an optimization problem for a model of steady state water transport through plants that maximizes water flow subject to the constraints on hydraulic conductance due to vulnerability to embolism (air blockage of conduits). The model has an elementary geometric interpretation, and exhibits bottleneck behavior where one of the plant segments ...

Complications of Embolization [PDF]
Seminars in Interventional Radiology, 2006 Embolization is a remarkably versatile procedure used in nearly all vascular and nonvascular systems to treat a wide range of pathology. The published literature is rich with studies demonstrating the enormous therapeutic potential offered by embolization procedures, and the possibilities continue to expand with the advent of new embolization agents ...

Rapid Blood Clot Removal via Remote Delamination and Magnetization of Clot Debris
Advanced Science, EarlyView.A programmable colloidal microswarm is developed to quickly detach blood clots and enable rapid recanalization, with the detached debris functioning as a magnetic “debris‐robot” that can be efficiently propelled and retrieved via catheter suction, which could significantly save time compared to the critical “Golden 6 hours” window for ischemic stroke ...

Paraclinoid unruptured giant aneurysm with therapeutic success
Exploration of Neuroprotective Therapy, 2022 The global prevalence of intracranial aneurysms (IA) ranges from 5–10%, with a demographic variation. Large and giant aneurysms typically involve cavernous and paraclinoid segments of the internal carotid artery (ICA), and represent 5% of IA.

PECon: Contrastive Pretraining to Enhance Feature Alignment between CT and EHR Data for Improved Pulmonary Embolism Diagnosis [PDF]
arXiv, 2023 Previous deep learning efforts have focused on improving the performance of Pulmonary Embolism(PE) diagnosis from Computed Tomography (CT) scans using Convolutional Neural Networks (CNN). However, the features from CT scans alone are not always sufficient for the diagnosis of PE.
