BACKGROUND The study aimed to investigate the influence of hyperglycemia on muscle quality in older men with type 2 diabetes. METHODS This was a subsidiary study of the Korean Longitudinal Study of Health and Aging. Among 326 older men consenting to tests of body composition and muscle strength, 269 men were ultimately analyzed after the exclusion because(More)
OBJECTIVE We investigated the prevalence of sarcopenic obesity (SO) and its relationship with metabolic syndrome in a community-based elderly cohort in Korea. RESEARCH DESIGN AND METHODS In this study, 287 men and 278 women aged 65 or older were recruited. Sarcopenia was defined as the appendicular skeletal muscle mass (ASM) divided by height squared(More)
The uniform growth of single-crystal graphene over wafer-scale areas remains a challenge in the commercial-level manufacturability of various electronic, photonic, mechanical, and other devices based on graphene. Here, we describe wafer-scale growth of wrinkle-free single-crystal monolayer graphene on silicon wafer using a hydrogen-terminated germanium(More)
Age-related body composition changes such as sarcopenia and obesity affect functional decline in the elderly. We investigated the relationship between body composition parameters and functional limitation in older Korean adults. We enrolled 242 men and 231 women aged ≥ 65 yr from the Korean elderly cohort. We used appendicular skeletal muscle mass (ASM)(More)
IMPORTANCE This study presents an innovative method for developing a neuromuscular model of obstructive sleep apnea (OSA). OBJECTIVE To establish a new OSA animal model simulating real upper airway conditions during sleep. DESIGN AND SETTING In vivo animal study at an academic tertiary referral center. SUBJECTS A total of 27 New Zealand white male(More)
Edge detection is a significant step in image processing. Morphological edge detectors developed until now used a fixed structuring element (SE) on all the image pixels; however, they cannot consider the local features of an image due to the fixed SE and we should choose an appropriate SE by lots of experiments. In this paper, new morphological edge(More)
We describe cardiovascular responses during the Valsalva maneuver and syncope in the youngest reported patient with stretch syncope, which was induced by neck stretching and back hyperextension. The pattern of cardiovascular responses during stretch syncope was similar to that during a pathologic Valsalva maneuver, indicating adrenergic dysfunction in this(More)
PURPOSE αB-crystallin is a small heat shock protein that acts as a molecular chaperone under various stress conditions. Microtubules, which consist of tubulin, are related to maintain the intracellular organelles and cellular morphology. These two proteins have been shown to be related to the properties of different types of myofibers based on their(More)
Although sodium nitroprusside (SNP) is often used in pediatric intensive care units, cyanide toxicity can occur after SNP treatment. To treat SNP-induced cyanide poisoning, antidotes such as amyl nitrite, sodium nitrite, sodium thiosulfate, and hydroxycobalamin should be administered immediately after diagnosis. Here, we report the first case of a very(More)
PURPOSE The management and clinical course in pediatric patients who had ingested foreign body were investigated retrospectively to evaluate the frequency and factor associated with successful removal of fishbone foreign body. METHODS Based on the medical records of patients younger than 15 years old who visited emergency room because of foreign body(More)
