The cellular entry of Hantaan virus (HTN) occurs through interactions with beta(3) integrins as cellular receptors. However, the process of HTN infection following attachment to the cell surface is not well understood. Our data indicate that overexpression of a dominant-negative mutant dynamin inhibits HTN internalization and that compounds that block(More)
BACKGROUND AND PURPOSE Elevated blood pressure (BP) is commonly observed in acute ischemic stroke and is known to be associated with hemorrhagic transformation (HT). However, the effect of BP variability on the development of HT is not known well. METHODS A consecutive series of patients with acute ischemic stroke, who were hospitalized within 24 hours of(More)
INTRODUCTION Since the introduction of laparoscopic surgery, surgeons have not only been concerned about clinical outcomes, but also surgical scars. Although natural orifice transluminal endoscopic surgery (NOTES) is promising, it is not applicable to clinical practice thus far due to safety concerns. As a transitional procedure between standard(More)
When we look at a clock with a hand showing seconds, the hand sometimes appears to stay longer at its first-seen position than at the following positions, evoking an illusion of chronostasis. This illusory extension of perceived duration has been shown to be coupled to saccadic eye movement and it has been suggested to serve as a mechanism of maintaining(More)
PURPOSE Liver resection (LR) and liver transplantation (LT) are considered the only two potentially curative treatments for hepatocellular carcinoma (HCC). Recently, there has been an intense debate as to whether LR or LT is the optimal initial treatment for patients with Child A or B cirrhosis. The aim of this study was to compare the results of LR and LT(More)
Understanding preference decision making is a challenging problem because the underlying process is often implicit and dependent on context, including past experience. There is evidence for both familiarity and novelty as critical factors for preference in adults and infants. To resolve this puzzling contradiction, we examined the cumulative effects of(More)
Dysfunction and loss of retinal pigment epithelium (RPE) are major pathologic changes observed in various retinal degenerative diseases such as aged-related macular degeneration. RPE generated from human pluripotent stem cells can be a good candidate for RPE replacement therapy. Here, we show the differentiation of human embryonic stem cells (hESCs) toward(More)
BACKGROUND Conventional ultrasonography or magnetic resonance (MR) imaging is commonly performed to obtain information about the severity of the disease, location of the injury, and differential diagnosis. The aim of this research was to investigate the diagnostic confidence of sonoelastography as an adjunct to greyscale ultrasonography in lateral elbow(More)
Piriformis muscle syndrome (PMS) is a controversial neuromuscular disorder that is presumed to involve compression neuropathy of the sciatic nerve at the level of the piriformis muscle. Botulinum toxin A (BTX-A) injection into the piriformis muscle is widely used as a treatment aimed at relieving sciatic nerve compression. In 2 patients with PMS, magnetic(More)
PURPOSE The purpose of this study is to investigate how respiratory muscle strength correlates to cough capacity in patients with respiratory muscle weakness. MATERIALS AND METHODS Forty-five patients with amyotrophic lateral sclerosis (ALS), 43 with cervical spinal cord injury (SCI), and 42 with Duchenne muscular dystrophy (DMD) were recruited.
