PURPOSE The present study was aimed to assess the feasibility of using decellularized aortic allograft in a rat small animal surgical model for conducting small diameter vascular tissue engineering research. MATERIALS AND METHODS Decellularized aortic allografts were infra-renally implanted in 12 Sprague-Dawley (SD) adult rats. The conduits were harvested(More)
Implementing the effective and efficient planning methods is a critical means to gain competitiveness for the decision-maker of manufacturing enterprise in today’s global market. We proposed adaptive response mechanism based on the hybrid simulation and optimization (ARESOP) that provides a formal bridge between long-term plans and short-term(More)
OBJECTIVE The presence of a giant left atrium (LA) is strongly associated with the recurrence of atrial fibrillation (AF) after the maze procedure. Therefore, we investigated the factors affecting the rhythm outcomes after the maze procedure in patients with a giant LA and AF-associated mitral valve disease to determine the best candidates for the maze(More)
BACKGROUND The standard approach in treating cardiac myxoma is the median full sternotomy. With the evolution of surgical techniques, the right minithoracotomy approach has emerged as an alternative method. Since few studies have been published assessing the right minithoracotomy approach, we performed a retrospective study to compare the clinical outcomes(More)
Essential thrombocytosis (ET) is a myeloproliferative disorder characterized by an anomalous increase in platelet production. Many patients with ET are asymptomatic. Few studies have reported ET-associated thromboembolism in large vessels such as the aorta. We report a patient with ET who presented with peripheral embolism from an abdominal aortic thrombus(More)
Nanostructured silicon (Si) is useful in many applications and has typically been synthesized by bottom-up colloid-based solution processes or top-down gas phase reactions at high temperatures. These methods, however, suffer from toxic precursors, low yields, and impractical processing conditions (i.e., high pressure). The magnesiothermic reduction of(More)
A 43-year-old man experienced chest trauma due to a car accident. Compound sternal fractures with severe dislocation were seen on computed tomography of the chest. Using a SternaLock plating system with manual reduction, fixation of the sternal fracture was successfully performed. There were no complications related to the operation.
OBJECTIVES Pericardial effusion can cause haemodynamic compromise after heart transplantation. We identified the effects of soft drains on the development of pericardial effusion. METHODS We enrolled 250 patients ≥17 years of age who underwent heart transplantation between July 1999 and April 2012 and received two conventional tubes (n = 96; 32 French),(More)
