This is a short review paper presenting hypothesis to explain the mechanism that may be involved in the genesis of sleep bruxism (SB). In humans, SB is a repetitive sleep movement disorder mainly characterized by rhythmic masticatory muscle activity (RMMA) at a frequency of 1Hz and by occasional tooth grinding. Until recently, the mechanism by which RMMA(More)
We found that Icaritin, an intestinal metabolite of Epimedium-derived flavonoids (EF) enhanced osteoblastic differentiation of mesenchymal stem cells (MSCs) only under osteogenic induction conditions. We also demonstrated its effect on inhibition of adipogenic differentiation of MSCs. Unlike the findings of others on EF compounds, we showed that Icaritin(More)
Tumor suppressor gene p53 functions as the guardian of the human genome and mutations in p53 contribute to cancer development. However, studies that investigated the potential of p53 as a prognostic marker in osteosarcoma patients have yielded inconclusive results. Based on recommendation of the Cochrane Collaboration, this meta-analysis was conducted using(More)
This study was designed to develop a bioactive scaffold to enhance bone defect repair in steroid-associated osteonecrosis (SAON). Icaritin, a metabolite of the herb Epimedium, has been identified as an angiogenic and osteogenic phytomolecule. Icaritin was homogenized into poly lactic-co-glycolic acid/tricalcium phosphate (PLGA/TCP) to form an(More)
Steroid-associated osteonecrosis (SAON) may lead to joint collapse and subsequent joint replacement. Poly lactic-co-glycolic acid/tricalcium phosphate (P/T) scaffold providing sustained release of icaritin (a metabolite of Epimedium-derived flavonoids) was investigated as a bone defect filler after surgical core-decompression (CD) to prevent femoral head(More)
Epimedium flavonoids inhibit extravascular lipid deposition during prevention of steroid-associated osteonecrosis. Desmethylicaritin is a bioactive metabolite of Epimedium flavonoids in serum. As it is well known that estrogen inhibits aidpogenesis, so we hypothesized that desmethylicaritin as a phytoestrogen might have the potential to inhibit lipid(More)
This study aimed to evaluate the validation of the leptin receptor-deficient mice model for secondary osteoporosis associated with type 2 diabetes mellitus (T2DM) at bone micro-architectural level. Thirty three 36-week old male mice were divided into four groups: normal control (db/m) (n = 7), leptin receptor-deficient T2DM (db/db) (n = 8), human C-reactive(More)
Purpose: The clinical role of TOP2A as a prognostic indicator for breast cancer has not been well examined. The aims of this study were to detect expression of the topoisomerase 2A (TOP2A) protein, to investigate the relationship between TOP2A andhuman epidermal growth factor receptor-2 (HER2) status or hormone receptor (HR) expression, and to further(More)
