BACKGROUND Osteoporosis associated with thyroid dysfunction has been traditionally viewed as a secondary consequence of altered thyroid function, but there was recently a report about the direct effects of thyroid-stimulating hormone (TSH) on bone remodeling, which was mediated via the TSH receptor found on osteoblast and osteoclast precursor cells.(More)
OBJECTIVE Body weight is a significant predictor of bone mass. Hormonal factors such as sex hormones, insulin, leptin and adiponectin are thought to play a role in the mechanisms controlling the association of body weight and fat mass with bone mass. However, contradictory results have been reported for the association between serum adipocytokines and bone(More)
Some papers have suggested that alkaline phosphatase (ALP) level is a predictor of the metabolic syndrome (MetS) in the general population. However, the association is still controversial, and the mechanisms underlying an association between ALP level and the MetS have not been elucidated. We analyzed the association between serum ALP level and the(More)
Recent studies suggest an association of vitamin D with obesity, diabetes and cardiovascular diseases. We analyzed the association of serum vitamin D level assessed by 25-hydroxyvitamin D3 {25(OH)D3 } with nonalcoholic fatty liver disease (NAFLD) in apparently healthy men. We performed a cross-sectional study of 6,567 Korean men who participated in a health(More)
BACKGROUND Periostin is preferentially expressed by the periosteum, which mainly covers the long bones. Therefore, the role of periostin in osteoporotic fracture (OF) may differ depending on bone type. We performed a case-control study to investigate whether periostin can serve as a predictor of OF risk, particularly after dividing OFs into non-vertebral(More)
It has been suggested that oxidative stress is associated with the pathogenesis of osteoporosis. The objective of this study was to explore the association between a marker of oxidative stress and either bone turnover markers or bone mineral density (BMD) in postmenopausal women. In addition, the effects of oxidative stress on the formation of osteoclasts(More)
OBJECTIVE Osteoporosis is a growing health problem in males as well as in females. Sex hormones and insulin-like growth factor-I (IGF-I) have been shown to be the major determinants in male bone metabolism. Osteoprotegerin (OPG) is a recently identified cytokine that acts as a decoy receptor for the receptor activator of NF-kappaB ligand (RANKL). OPG and(More)
OBJECTIVE We analyzed the sonographic characteristics of thyroid nodules and assessed the diagnostic value of ultrasonography in order to distinguish between benign and malignant lesions in terms of the management of thyroid nodules. DESIGN We retrospectively analyzed the sonographic features of thyroid nodules in 580 patients who had been examined with(More)
Statins have been postulated to affect the bone metabolism. Recent experimental and epidemiologic studies have suggested that statins may also have bone protective effects. This study assessed the effects of simvastatin on the proliferation and differentiation of human bone marrow stromal cells (BMSCs) in an ex vivo culture. The bone marrow was obtained(More)
OBJECTIVE To clarify the association of serum calcium level with metabolic syndrome (MetS) and diabetes in middle-aged and elderly Korean subjects. DESIGN AND PATIENTS We conducted a population-based, cross-sectional survey of 1329 participants aged over 40 years (median age 65.8) in a rural area of Chungju, Korea, in 2007. MEASUREMENTS Serum level of(More)
