Vascular remodeling of the mouse yolk sac requires hemodynamic force [PDF]
, 2007 The embryonic heart and vessels are dynamic and form and remodel while functional. Much has been learned about the genetic mechanisms underlying the development of the cardiovascular system, but we are just beginning to understand how changes in heart ...

A Hierarchical Image Matting Model for Blood Vessel Segmentation in Fundus Images [PDF]
IEEE Transactions on Image Processing, 2017 In this paper, a hierarchical image matting model is proposed to extract blood vessels from fundus images. More specifically, a hierarchical strategy is integrated into the image matting model for blood vessel segmentation.

Elevating microRNA-122 in blood improves outcomes after temporary middle cerebral artery occlusion in rats. [PDF]
, 2016 Because our recent studies have demonstrated that miR-122 decreased in whole blood of patients and in whole blood of rats following ischemic stroke, we tested whether elevating blood miR-122 would improve stroke outcomes in rats.

Labyrinthine artery aneurysm as an internal auditory canal mass. [PDF]
, 2014 We present the first case report of a labyrinthine artery aneurysm masquerading as an internal auditory canal tumor. A 72-year-old woman presented with sudden onset right facial paralysis, facial pain, hearing loss, and vertigo.

A retinal image enhancement technique for blood vessel segmentation algorithm [PDF]
International Conference on Industrial and Information Systems, 2017 The morphology of blood vessels in retinal fundus images is an important indicator of diseases like glaucoma, hypertension and diabetic retinopathy. The accuracy of retinal blood vessels segmentation affects the quality of retinal image analysis which is

Microstructured Thin Film Nitinol for a Neurovascular Flow-Diverter [PDF]
, 2016 A cerebral aneurysm occurs as a result of a weakened blood vessel, which allows blood to flow into a sac or a ballooned section. Recent advancement shows that a new device, ‘flow-diverter’, can divert blood flow away from the aneurysm sac.

Modelling Dynamically Re-sizeable Electrodes (DRE) for Targeted Transcutaneous Measurements in Impedance Plethysmography [PDF]
, 2020 Impedance plethysmography of extremities typically uses band electrodes around limbs to monitor changes in blood volume. This often causes monitored blood variations to only generate minuscule impedance values relative to the measured baseline ...
