BACKGROUND Frequent idiopathic premature ventricular complexes (PVCs) can result in a reversible form of left ventricular dysfunction. The factors resulting in impaired left ventricular function are unclear. Whether a critical burden of PVCs can result in cardiomyopathy has not been determined. OBJECTIVE The objective of this study was to determine a(More)
Cervical cancer is the second leading cause of cancer in women worldwide. Human papillomavirus (HPV) is responsible for all cases of cervical cancer. Commercial prophylactic HPV vaccines are now available, but unfortunately these vaccines have no therapeutic effect against established HPV infections. In order to accelerate the control of cervical cancer and(More)
We synthesized a library of polymer-coated gold nanoparticles (AuNPs) with well-defined sizes (5, 10, and 20 nm) and surface properties, and investigated their efficiency to cross the Caco-2 epithelial barrier and disrupt tight junctions connecting the cellular barrier. The positively charged and hydrophobic polymer-coated AuNPs showed little or no(More)
BACKGROUND The value of the 12-lead electrocardiogram (ECG) to identify the exit site of postinfarction ventricular tachycardia (VT) has been questioned. The purpose of this study was to assess the accuracy of a computerized algorithm for identifying a VT exit site on the basis of the 12-lead ECG. METHODS AND RESULTS In 34 postinfarction patients, pace(More)
INTRODUCTION Toll-like receptors (TLRs) are a crucial part of the innate immunity and present the first line of defense against pathogens. In humans, there are ten TLRs, with TLR3, 7, 8 and 9 located in intracellular vesicles and the remaining expressed on the cell surface. These transmembrane protein receptors recognize a wide range of pathogen components.(More)
UNLABELLED The different transport pathways of 5-nm polymer-coated gold nanoparticles (Au NPs) crossing epithelial Caco-2 cell monolayers were explored. We found that the majority of cationic and neutral Au NPs depended heavily on endocytosis for cellular uptake and transport, and the anionic charged nanoparticles trafficked preferentially through the tight(More)
We introduce an approach to sparsity penalized multi-class classifier design that accounts for multi-block structure of the data. The unified multi-class classifier is parameterized by a set of weights defined over the classes and over the blocks. The proposed sparse multi-block multi-class classifier imposes structured sparsity on the weights so that the(More)
OBJECTIVES The purpose of this study was to assess the value of implantable cardioverter-defibrillator (ICD) electrograms (EGMs) in identifying clinically documented ventricular tachycardias (VTs). BACKGROUND Twelve-lead electrocardiograms (ECG) of spontaneous VT often are not available in patients referred for catheter ablation of post-infarction VT.(More)
