AIM Mesenchymal stromal cells from human bone marrow (hMSCs) were observed to produce therapeutic benefits in some models for cardiac and vascular injuries but their mode of action was not defined. We tested the effects of hMSCs in models for restricted vascular flow. METHODS We made model for restricted vascular flow produced by permanent ligation of a(More)
AIM To investigate whether there is a link between bovine arch and thoracic aortic aneurysm. MATERIALS AND METHODS Computed tomography (CT) and magnetic resonance imaging (MRI) images of the thorax of 191 patients with dilated thoracic aortas and 391 consecutive, unselected patients as controls were retrospectively reviewed. Bovine arch was considered(More)
We present a new class of ultrasound molecular imaging agents that extend upon the design of micromotors that are designed to move through fluids by catalyzing hydrogen peroxide (H₂O₂) and propelling forward by escaping oxygen microbubbles. Micromotor converters require 62 mm of H₂O₂ to move - 1000-fold higher than is expected in vivo. Here, we aim to prove(More)
OBJECTIVES This study evaluated a simple relaxation breathing exercise for acute improvement of postprandial glycemic and insulinemic status. DESIGN Healthy human subjects were randomized to control breathing (CB; n=13) or a relaxation breathing exercise (RB; n=13) that was repeated every 10 minutes for the 30 minutes before and 90 minutes after consuming(More)
OBJECTIVE We report here an initial experience using 4D flow MRI in pelvic imaging-specifically, in imaging uterine fibroids. We hypothesized that blood flow might correlate with fibroid volume and that quantifying blood flow might help to predict the amount of embolic required to achieve stasis at subsequent uterine fibroid embolization (UFE).

By virtue of its information technology-oriented infrastructure, the specialty of radiology is uniquely positioned to be at the forefront of efforts to promote data sharing across the healthcare enterprise, including particularly image sharing. The potential benefits of image sharing for clinical, research, and educational applications in radiology are(More)
PURPOSE The ability to detect small malignant lesions with magnetic resonance imaging (MRI) is limited by inadequate accumulations of Gd with standard chelate agents. To date, no T1-targeted agents have proven superiority to Gd chelates in their ability to detect small tumors at clinically relevant field strengths. Activatable cell-penetrating peptides and(More)
Oxidative stress is a powerful tool that is critical to immune mediated responses in healthy individuals, yet additionally plays a crucial role in development of cancer, inflammatory pathologies, and tissue ischemia. Despite this, there remain relatively few molecular tools to study oxidative stress, particularly in living mammals. To develop an(More)
Bronchial artery embolization is an effective nonsurgical therapy for massive hemoptysis. Routine selection of the bronchial arteries from the aorta usually enables the interventionalist full interrogation and embolization of the culprit vascular abnormality. In problematic cases where bronchial artery access is difficult, a systemic-to-pulmonary arterial(More)
