BACKGROUND Sarcopenia is an important factor of functional impairment related to aging. This study is conducted to investigate the prevalence of sarcopenia and sarcopenic obesity in Korean population. METHODS Representative Korean men (4,486) and women (5,999) aged 20 years or older were analyzed from the Fourth Korean National Health and Nutritional(More)
OBJECTIVE this study examined the association of physical activity with sarcopenia and sarcopenic obesity among the community-dwelling Korean elderly. METHODS subjects consisted of 2,264 aged 65 years or older in the 2008-09 Korea National Health and Nutrition Examination Survey. Sarcopenia was defined as 2 SD below the mean of the appendicular skeletal(More)
It is well established that insulin-like growth factor (IGF)-I is critical for the regulation of peak bone mineral density (BMD) and bone width. However, the role of systemic vs. local IGF-I is not well understood. To determine the role local IGF-I plays in regulating BMD and bone width, we crossed IGF-I flox/flox mice with procollagen, typeIIalphaI-Cre(More)
It is debatable whether Hajdu-Cheney syndrome (HCS) and serpentine fibula-polycystic kidney syndrome (SFPKS) represent a single clinical entity with a variable degree of expression or two different entities, because both disorders share common clinical and radiological manifestations, including similar craniofacial characteristics, and defective bone(More)
The aims of this study were to compare the prevalence of the metabolic syndrome according to the WHO and NCEP ATP III criteria in Korean adults, and to compare the prevalence of the metabolic syndrome with the results in previous Korean studies. The study comprised 1,230 subjects (627 men, 603 women) aged 30-79 years (mean 52.4 +/- 10.3 years) who underwent(More)
In this study, the authors compared bone mineral density (BMD) determined using GE Lunar iDXA and Prodigy and derived cross-calibration equations for the 2 devices in Korean adults. One hundred subjects (66 women and 34 men) participated in this study. Bone mineral density of spine and femur was measured by iDXA and Prodigy dual-energy X-ray absorptiometry(More)
For the prevention of osteoporotic fracture, adequate screening and treatment are important. However, there are few published data on diagnosis and treatment rates of osteoporosis in Asia. We used data from the fourth Korea National Health and Nutrition Examination Survey 2008-2009 to estimate the nationwide prevalence, physician diagnosis rate, and(More)
UNLABELLED Using a mouse mutant that fractures spontaneously and dies at a very young age, we identified that a deletion of the GULO gene, which is involved in the synthesis of vitamin C, is the cause of impaired osteoblast differentiation, reduced bone formation, and development of spontaneous fractures. INTRODUCTION A major public health problem(More)
We report an unusual case of osteoblastic metastasis from gastric carcinoma. In this case, bone metastasis was the initial manifestation of the cancer. The laboratory findings revealed mild hypocalcemia and markedly elevated alkaline phosphatase levels. Plain X-ray showed mottled osteoblastic changes in the pelvis. Bone marrow and bone biopsy of the pelvis(More)
Silicon is important for the proper growth and development of bone and connective tissues. This study was designed to investigate if water-soluble silicon could be used for the treatment of postmenopausal osteoporosis. Silicon (Si 20 mg/kg body weight/day) was administrated orally to 17-week-old ovariectomized (OVX) rats for 4 weeks. Silicon did not alter(More)
