Quantification of right ventricular (RV) volume and function remains a challenge because of RV complex geometry by conventional echocardiography. The purpose of this study was to assess RV global longitudinal function in patients with tetralogy of Fallot (TOF) by 2-dimensional ultrasound speckle tracking imaging (STI). Thirty-eight patients with TOF were(More)
Ultrasound-mediated microbubble destruction (sonoporation) is an efficient and safe nonviral technique for gene delivery. In the present work, we hypothesized that short hairpin RNA (shRNA) interference therapy targeting human Survivin gene could be transfected by the novel combination of ultrasound exposure (USE) and liposome microbubbles (LM). ShRNA(More)
This study evaluated the change in regional left ventricular myocardial function in rats following acute occlusion of the left anterior descending coronary artery (LAD) by using two-dimensional speckle tracking imaging (2D-STI). Sixty Wistar rats were randomly divided into two groups, a myocardial infarction (MI) group, in which 50 rats were subjected to(More)

It is important to analyze the influence factors of customer values in order to provide a guideline of successful B2C. The purpose of this paper is to build up the evaluation factors of customer value and answer the following questions. First, what are key components of customer value in B2C companies? Second, what is the most important evaluation factor in(More)
Cardiac lipoma, which are primary cardiac tumors, are rare entities often detected incidentally during imaging. There have been very few reports on the right ventricle (RV) lipoma. Here, we present a case of RV infiltrating lipoma involving the interventricular septum (IVS) and the tricuspid valve. Clinical symptoms, diagnostic procedures, multimodality(More)
Hypoxia-inducible factor 1α (HIF-1α) plays a critical protective role in ischemic heart disease. Under normoxic conditions, HIF-1α was degraded by oxygen-dependent prolyl hydroxylase-2 (PHD2). Gene therapy has become a promising strategy to inhibit the degradation of HIF-1α and to improve cardiac function after ischemic injury. However, conventional gene(More)
To evaluate the morphology of atrial septum by the live three-dimensional echocardiography (L3DE) and its value of clinical application, L3DE was performed in 62 subjects to observe the morphological characteristics and dynamic change of the overall anatomic structure of atrial septum. The study examined 49 patients with atrial septal defect (ASD),(More)
