OBJECTIVES The aims of this study were to determine D-shaped mitral annulus (MA) dimensions in control subjects without significant cardiac disease and in patients with moderate to severe mitral regurgitation (MR) being considered for transcatheter mitral therapy and to determine predictors of annular size, using cardiac computed tomography. BACKGROUND The recently introduced D-shaped method ...
Blood oxygen level–dependent functional MR (BOLD fMR) imaging, long accepted as a powerful research technique in the cognitive sciences and neurosciences, recently has gained acceptance as a clinical tool. Clinical applications of BOLD imaging have focused primarily on the preoperative locali-zation of the motor, sensory, and language centers of the brain in anticipation of tumor or vascular ma...
BACKGROUND Lipodystrophies are characterized by adipose tissue redistribution, insulin resistance (IR) and metabolic complications. Adipokines and hormones related to body composition may play an important role linking these alterations. Our aim was to evaluate adipocyte-derived hormones (adiponectin, leptin, resistin, TNF-α, PAI-1) and ghrelin plasma levels and their relationship with IR in HI...
OBJECTIVES we sought to determine whether patients with functional mitral regurgitation (FMR) would benefit from ventricular reshaping by the Coapsys device (Myocor, Inc., Maple Grove, Minnesota). BACKGROUND FMR occurs when ventricular remodeling impairs valve function. Coapsys is a ventricular shape change device placed without cardiopulmonary bypass to reduce FMR. It compresses the mitral a...
Ferromagnetic nanowires showed solitary and tunable magnetization properties due to their inherent shape anisotropy. The fabrication of such nanowires in polycarbonate track-etched and anodic alumina membranes have been widely studied during the last 15 years [1-2]. Their potential applications might be explored in spintronic devices and more specifically in magnetic random access memory (MRAM)...
The objective of the paper is to develop a “lab-on-a-chip” device for early disease (pancreatic cancer) diagnosis by using ferromagnetic resonance (FMR). Magnetic microbeads, which are functionalized for target molecules (antigens), are immobilized by antigen-antibody reactions on the surface of a microwave circuit. These magnetic labels are detected inductively using FMR, which detects a singl...
The longitudinal magneto-optical Kerr effect is used to obtain a calibrated measure of the dynamic magnetization response over the ferromagnetic resonance (FMR) profile for in-plane magnetized Permalloy films excited with high power in-plane transverse microwave fields at 1.25 to 3.75 GHz and in-plane precession angles up to about 20 degrees. The data provide a profound demonstration of the Suh...
This paper considers the use of the EM-algorithm, combined with mean field theory, for parameter estimation in Markov random field models from unlabelled data. Special attention is given to the theoretical justification for this procedure, based on recent results from the machine learning literature. With these results established, an example is given of the application of this technique for an...
