Lon, also known as protease La, belongs to a class of ATP-dependent serine protease. It plays an essential role in degradation of abnormal proteins and of certain short-lived regulatory proteins, and is thought to possess a Ser-Lys catalytic dyad. To examine the structural organization of Lon, we performed an electron microscope analysis. The averaged(More)
BACKGROUND Ethnic and geographic differences exist in the prevalence of diabetes mellitus which has increased dramatically in South Korea. A few community-based epidemiologic studies with oral glucose tolerance test were performed in South Korea. The purpose of this study was to determine the prevalence of diabetes mellitus by the World Health Organization(More)
Most colonic multiple mucosa-associated lymphoid tissue (MALT) lymphomas are confirmed with a histologic and immunohistochemical staining of the mucosal biopsy specimen obtained during colonoscopic examinations. Endoscopically, colonic MALT lymphomas frequently appear as protruding and/or ulcerative lesions, and there are not so many reports of colonic MALT(More)
Biologically functional protein arrays are important for chip-based protein detection assays and proteomic profiling experiments. [1–3] Nanoscale arrays allow for smaller chips with more reaction sites, smaller test sample volumes, potentially higher sensitivity and speed, and direct feature analysis with a scanning probe instrument. [4–11] Several(More)
BACKGROUND AND OBJECTIVES Transradial coronary angiography and intervention are increasing in frequency due to lower major vascular access site complications and the potential for early mobilization. However, the small size of the radial artery (RA) is a major limitation of this technique. A sheathless guiding catheter (GC) has recently been introduced that(More)
Service composition provides feasible ways to flexibly build m edia applications employing widely dispersed media contents and tools. There have been several attempts to enable media-oriented service composition based on service over-lay networks (SONs). To enhance the flexibility of media-oriented service composition for Future Internet, we introduce an(More)
PURPOSE Early pubertal timing in girls is associated with psychological and behavioral problems. This study aimed to evaluate the psychological features of girls who perceived breast development beginning by analyzing their depression levels and self-concept. METHODS From March 2007 to December 2012, 93 girls were enrolled and assigned to a pre-8 (younger(More)
In the human mechanosensation system, rapidly adapting afferents project sensory signals of flutter (5-50Hz) to the contralateral primary somatosensory cortex (S1) and bilateral secondary somatosensory cortex (S2) whereas Pacinian afferents project sensory signals of vibration (50-400Hz) to bilateral S2. However, it remains largely unknown how somatosensory(More)
Slow-adapting type I (SA-I) afferents deliver sensory signals to the somatosensory cortex during low-frequency (or static) mechanical stimulation. It has been reported that the somatosensory projection from SA-I afferents is effective and reliable for object grasping and manipulation. Despite a large number of neuroimaging studies on cortical activation(More)
Esophageal duplication (ED) is rarely diagnosed in adults and is usually asymptomatic. Especially, ED that is connected to the esophagus through a tubular communication and combined with bronchoesophageal fistula (BEF) is extremely rare and has never been reported in the English literature. This condition is very difficult to diagnose. Although some(More)
