Hemosuccus Pancreaticus as a Rare Complication of Bariatric Surgery. [PDF]

open access: yes, 2007
Hemosuccus pancreaticus is a rare cause of gastrointestinal bleeding from the duct of Wirsung into the duodenum via the ampulla of Vater. Hemosuccus pancreaticus is difficult to diagnose because the bleeding is usually intermittent, and the clinical ...

Statistical physics of cerebral embolization leading to stroke [PDF]

open access: yesPhys. Rev. E vol. 80, 051912 (2009), 2008
We discuss the physics of embolic stroke using a minimal model of emboli moving through the cerebral arteries. Our model of the blood flow network consists of a bifurcating tree, into which we introduce particles (emboli) that halt flow on reaching a node of similar size.

Hemobilia from biliary angiodysplasia diagnosed with cholangioscopy [PDF]

open access: yes, 2016
Biliary angiodysplasia is extremely rare. Our background search revealed only a few case reports in the English literature. We present a case of angiodysplasia of the proximal common bile duct in a patient with subacute upper gastrointestinal bleeding ...

An In Situ Curing, Shear‐Responsive Biomaterial Designed for Durable Embolization of Microvasculature

open access: yesAdvanced Healthcare Materials, EarlyView.
NeoCast is a next‐generation, solvent‐free, non‐adhesive liquid embolic designed for indications where deep occlusion is desired (e.g., tumors and chronic subdural hematoma). This novel agent offers ideal embolic properties: injectability, controllability, excellent visibility, and biocompatibility.

Automatic Diagnosis of Pulmonary Embolism Using an Attention-guided Framework: A Large-scale Study [PDF]

open access: yesarXiv, 2020
Pulmonary Embolism (PE) is a life-threatening disorder associated with high mortality and morbidity. Prompt diagnosis and immediate initiation of therapeutic action is important. We explored a deep learning model to detect PE on volumetric contrast-enhanced chest CT scans using a 2-stage training strategy. First, a residual convolutional neural network

Computerized Tomography Pulmonary Angiography Image Simulation using Cycle Generative Adversarial Network from Chest CT imaging in Pulmonary Embolism Patients [PDF]

open access: yesarXiv, 2022
The purpose of this research is to develop a system that generates simulated computed tomography pulmonary angiography (CTPA) images clinically for pulmonary embolism diagnoses. Nowadays, CTPA images are the gold standard computerized detection method to determine and identify the symptoms of pulmonary embolism (PE), although performing CTPA is harmful

The watering of tall trees - Embolization and recovery [PDF]

open access: yesJournal of Theoretical Biology, Elsevier, 2015, 369, pp.42 - 50, 2014
We can propound a thermo-mechanical understanding of the ascent of sap to the top of tall trees thanks to a comparison between experiments associated with the cohesion-tension theory and the disjoining pressure concept for liquid thin-films. When a segment of xylem is tight-filled with crude sap, the liquid pressure can be negative although the ...

Biomimetic Glycosaminoglycan‐Analog Hydrogel for Improved Embolization of Aneurysms: Environment‐Selective Swelling

open access: yesAdvanced Healthcare Materials, EarlyView.
Biomimetic glycosaminoglycan analog hydrogels exhibit suitable and robust mechanical properties, as well as hemocompatibility and biocompatibility, making them ideal for the embolization of intracranial aneurysms. Notably, the hydrogel's environment‐selective swelling properties enable complete blockage of the aneurysm cavity while preventing ...

Hemobilia due to cystic artery pseudoaneurysm: A rare late complication of laparoscopic cholecystectomy [PDF]

open access: yes, 2017
We discuss a patient with late presentation of hemobilia following cholecystectomy, which is unusual because pseudoaneurysm caused by vascular injury during surgery typically presents soon after surgery.

Geometric Adjustment of T Cell‐Sensitive Nanorobots for Enhanced Stability

open access: yesAdvanced Healthcare Materials, EarlyView.
For the long‐term use of live dendritic cell (DC)‐based vaccines, nano bone marrow dendritic cell (BMDC) originated T cell activators (nano‐BOTs) are synthesized. The geometric properties of nanoparticles are precisely modulated, enhancing their stability and T cell activation capacity.
