PURPOSE To assess the accuracy of emergency abdominal ultrasonography (US) in the detection of both hemoperitoneum and parenchymal organ injury in children. MATERIALS AND METHODS Imaging findings were recorded prospectively in 744 consecutive children who underwent emergency US from January 1995 to October 1998; free fluid and parenchymal abnormalities of(More)
OBJECTIVE We report the results of surgical treatment of Ebstein anomaly during a 10-year period, especially with an anatomic repair technique that restores to near normal anatomic and physiologic function of the tricuspid valve and the right ventricle. METHODS Between December 1997 and December 2006, 83 consecutive patients aged 9 months to 52 years(More)
We developed a simple strategy for designing a highly sensitive electrochemical biosensor for organophosphate pesticides (OPs) based on acetylcholinesterase (AChE) immobilized onto Au nanoparticles-polypyrrole nanowires composite film modifid glassy carbon electrode (labeled as AChE-Au-PPy/GCE). Where, the generated Au nanoparticles (AuNPs) were(More)
Echocardiography plays an important part in diagnostic aid in cardiology. During an echocardiogram exam images or image sequences are usually taken from different locations with various directions in order to comprehend a comprehensive view of the anatomical structure of the 3D moving heart. The automatic classification of echocardiograms based on the(More)
BACKGROUND Echocardiograms routinely sample pulmonary regurgitation signals from which it is possible to measure end diastolic gradients; these correlate with pulmonary artery diastolic pressures. METHODS We performed echocardiograms in 741 ambulatory adults with coronary artery disease who were recruited for the Heart and Soul Study. We compared(More)
A sensitive electrochemical stripping voltammetric biosensor is designed for organophosphate pesticides (OPs) based on solid-phase extraction (SPE) using Ni/Al layered double hydroxides (LDHs) modified glassy carbon electrode (labeled as Ni/Al-LDHs/GCE). The Ni/Al-LDHs as the host are highly efficient to capture OPs, which dramatically facilitates the(More)
This study extends the state of the art of deep learning convolutional neural network (CNN) to the classification of video images of echocardiography, aiming at assisting clinicians in diagnosis of heart diseases. Specifically, the architecture of neural networks is established by embracing hand-crafted features within a data-driven learning framework,(More)
UNLABELLED We introduce our surgical experience in treating recurrent aortic coarctation or coarctation associated with intracardiac abnormalities, which is difficult to manage. Four patients underwent the operation with hypothermic cardiopulmonary bypass. During the surgery, the posterior pericardium was opened and the thoracic aorta was dissected and(More)
