The high complexity and the short lifetime of 3D graphics acceleration hardware increase the necessity of an environment for hardware development. For easy modification and fast testing of architecture, a high-level language based environment is desirable. Therefore, in this paper we propose a Graphics Architecture Testing Environment (GATE) that is based(More)
PURPOSE As doxorubicin cardiotoxicity is considered irreversible, early detection of cardiotoxicity and prevention of overt heart failure is essential. Although there are monitoring guidelines for cardiotoxicity, optimal timing for early detection of subclinical doxorubicin cardiotoxicity is still obscure. The purpose of this study is to determine optimal(More)
BACKGROUND AND OBJECTIVES Pentraxin 3 (PTX3) was shown to be elevated in the acute phase of acute myocardial infarction (AMI) and to have prognostic significance in AMI patients. The aim of this study was to estimate whether the value of PTX3 could be used as a prognostic biomarker, with the global registry of acute coronary events (GRACE) risk assessment(More)
Papular elastorrhexis is a rare cutaneous disorder that occurs predominantly during adolescence. The disorder is characterized by asymptomatic indurated white or flesh papules showing decreased and fragmented elastic fibers in the dermis. We herein report on a 12-year-old girl with multiple asymptomatic white, nonfollicular, firm papules scattered on the(More)
BACKGROUND There exists a treatment challenge with periungual warts. Topical immunotherapy with diphenylcyclopropenone (DPCP) has recently been reported to be an effective treatment for recalcitrant warts, including periungual types. OBJECTIVE We aimed to evaluate the effectiveness and preference of topical immunotherapy with DPCP in treating periungual(More)
BACKGROUND AND OBJECTIVES The purpose of this study was to assess the value of C-type natriuretic peptide (CNP) as a surrogate marker for detection of coronary artery spasm in variant angina pectoris (VAP). SUBJECTS AND METHODS Sixty-six patients (mean age: 51±11 years, M : F=40 : 26) who underwent coronary angiography on suspicion of angina and who were(More)
BACKGROUND Ankyloglossia or tongue-tie is a congenital anomaly characterized by an abnormally short lingual frenum. Its prevalence in the newborn population is approximately 4%. Its mode of inheritance has been studied in some articles, but no conclusion has been established. Also, no relevant report has been published in Korea. This study was conducted to(More)
A 41-year-old woman who was diagnosed with myocarditis presented eosinophilia. Since the antibody against Toxocara canis (T. canis) was positive, we diagnosed that she had visceral larva migrans due to T. canis associated with myocarditis. She was treated with oral albendazole and prednisolone for two weeks, eosinophil count and hepatic enzymes were(More)
BACKGROUND AND OBJECTIVES It is known that angiotensin converting enzyme inhibitors and angiotensin II type 1 receptor blockers (ACEIs and ARBs, respectively) are effective in preventing atrial fibrillation (AF) in high-risk patients. However, it is not known whether ACEIs and ARBs are effective in preventing the recurrence of AF after catheter ablation. (More)
BACKGROUND AND OBJECTIVES It is widely known that both bone loss and vascular calcification are age-related processes. The purpose of this study was to investigate the relationship between coronary artery calcium (CAC) score or bone mineral density (BMD) with age and whether there is a gender difference factoring in the two conditions among healthy(More)
