PURPOSE To demonstrate 1-year outcomes after low-energy endovenous laser ablation (EVLA) of incompetent saphenous veins with linear endovenous energy density (LEED) of 80 J/cm or lower with the use of a 1,470-nm diode laser. MATERIALS AND METHODS Incompetent saphenous veins in 236 patients (355 limbs; Clinical/Etiology/Anatomy/Pathophysiology(More)
This paper proposes a method for saving resources of the video distribution server by using peer-to-peer communications. In order to adapt to a time-varying channel, scalable video coding and a fountain code, a Raptor code is used. The Raptor code protects video quality asymmetrically according to the significance of scalable video layers; varying in(More)
In this paper, we propose an effective relay communication for layered video transmission as an alternative to make the most of limited resources in a wireless communication network where loss often occurs. Relaying brings stable multimedia services to end clients, compared to multiple description coding (MDC). Also, retransmission of only parity data about(More)
OBJECTIVE The aim of this study was to identify the morphological and functional characteristics of quadricuspid aortic valves (QAV) on cardiac computed tomography (CCT). MATERIALS AND METHODS We retrospectively enrolled 11 patients with QAV. All patients underwent CCT and transthoracic echocardiography (TTE), and 7 patients underwent cardiovascular(More)
Benign fibrous histiocytoma (BFH) is a rare primary skeletal tumor, with reported incidence of 1% of all surgically managed benign bone tumors (1). BFH is composed of fibroblasts and histiocytes that are arranged in a storiform pattern, which has almost identical histological features to non-ossifying fibroma (NOF) (2). Therefore, BFH is distinguishable(More)
This paper proposes a method for retrieving the original information X out of multiple sets of side information (SI) such as Y1, Y2, Y3, etc. These sets are generated using key frames that are encoded by a conventional video codec. By using the method of majority rule, the most reliable bits from the decoded Yi’s are selected for the composition of Y∞, the(More)
DNA methylation at the 5th position of cytosine has been found to be correlated with tumorigenesis. An inhibitor of DNA methylase could, therefore, be used as an anticancer drug. However, only a few inhibitory compounds have been discovered due to the limitations for assaying the DNA methylation. In this study, we describe a modification of DNA(More)
A furocoumarin derivative, oxypeucedanin, was purified from Angelica dahurica, and its effects on the human Kv1.5 (hKv1.5) channel and on the cardiac action potential duration (APD), were examined using the patch-clamp technique and the conventional microelectrode technique. Oxypeucedanin inhibited the hKv1.5 current in a concentration-dependent manner,(More)
