BACKGROUND Repair of partial anomalous pulmonary venous connection (PAPVC) to the high portion of the superior vena cava (SVC) may be complicated by atrial arrhythmia and obstruction of the pulmonary veins or SVC. We reviewed our experience with the modified Warden technique, in which the SVC was transected and anastomosed to the right atrial appendage with(More)
This study determined the effects of alpha- and gamma-tocopherol supplementation on metabolic control and oxidative stress in type 2 diabetic Otsuka Long-Evans Tokushima Fatty (OLETF) rats. Blood glucose, haemoglobin A1c (HbA1c), urinary protein, plasma free fatty acid, triacylglycerol and plasminogen activator inhibitor-1 (PAI-1) levels in OLETF rats were(More)
PURPOSE Poststernotomy mediastinitis (PSM) following cardiovascular surgery remains an intractable complication associated with considerable mortality. It is therefore necessary to assess the risk factors associated with hospital mortality and evaluate the surgical treatment options for PSM. METHODS We identified 59 (2.2%) patients who developed PSM after(More)
A 69-year–old man was referred to our department for surgical treatment of bilateral giant coronary artery aneurysms. He had no apparent clinical factors associated with atherosclerosis, such as diabetes mellitus, hyperlipidemia, or hypertension. Physical examination revealed no abnormalities. His medical history included malignant lymphoma that had been(More)
Loading and releasing protein in a controllable way is extremely important for the protein vehicles used in bone tissue engineering. To obtain a suitable carrier material for basic proteins, such as BMP or bFGF, hydroxyapatite particles containing mercaptosuccinic acid (mercaptosuccinic acid (Mer), (Mer-HAp)) were synthesized. Physicochemical evaluation of(More)
BACKGROUND AND AIM OF THE STUDY The timing of the surgical intervention for active infective endocarditis (IE) is particularly difficult when there is a cerebrovascular complication. The study aim was to investigate the results of surgical treatment for active IE in patients with recent cerebrovascular events, and to evaluate the relationship between the(More)
The goal of this prospective study was to examine the effects of landiolol hydrochloride on prevention of atrial fibrillation and on hemodynamics in the acute postoperative phase after heart valve surgery. The subjects were 60 patients who underwent valve surgery at our hospital from April 2008 to July 2010. The patients were randomly divided into two(More)
Malignant pulmonary artery tumors represented by sarcomas are rare, but fatal. Early diagnosis and radical surgical resection offer the only chance for survival. However, surgical intervention has some challenging aspects, and prognosis is poor even after tumor resection. We report a case of a pulmonary artery sarcoma between the right ventricular outflow(More)
In this study, the effect of post acid treatments with HCl aqueous solutions after the hydrothermal process on the microstructure of TiO2-derived titanate nanotube was investigated. Especially, the relationship between local structural changes with the HCl treatment and their thermal stability were investigated by X-ray absorption fine structure (XAFS).(More)
Platypnea-orthodeoxia is a rare syndrome presenting with dyspnea and cyanosis induced by an upright position and relieved by recumbency. We report a patient with an excessively enlarged aortic root who had critical hypoxia due to a paradoxical shunt through the patent foramen ovale only when seated. The postural changes of the shunt, caused by changes in(More)
