Glutamate, an important central excitatory neurotransmitter, is also secreted by osteoblasts and may be involved in the regulation of bone metabolism. Glutamate receptors for N-methyl-D-aspartate (NMDA) and alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA) are demonstrated in bone cells. Here we investigated the in vivo effects of glutamate by(More)
Heme-oxygenase-1 (HO-1), an important enzyme involved in vascular disease, transplantation, and inflammation, catalyzes the degradation of heme into carbon monoxide and biliverdin. It has been reported that overexpression of HO-1 inhibits osteoclastogenesis. However, the effect of HO-1 on osteoblast differentiation is still not clear. We here used(More)
As human beings live longer, age-related diseases such as osteoporosis will become more prevalent. Intolerant side effects and poor responses to current treatments are observed. Therefore, novel effective therapeutic agents are greatly needed. Here, pyrazole derivatives were designed and synthesized, and their osteoclastogenesis inhibitory effects both in(More)
OBJECTIVE(S) Pregnancy is rare in patients on chronic dialysis, with only a 30-50% rate of successful delivery reported in a previous review article. The pregnancy outcome has improved in recent decades, but data on pregnancy outcome are limited due to the small sample size of previous case series. This study investigated the pregnancy outcome in patients(More)
Oncostatin M (OSM) belongs to IL-6 subfamily and is mostly produced by T lymphocytes. High levels of OSM are detected in the pannus of rheumatoid arthritis (RA) patients and it may arouse the inflammation responses in joints and eventually leads to bone erosion. Placenta growth factor (PLGF) is an angiogenic factor and highly homologous with vascular(More)
Peroxisome proliferator-activated receptor gamma (PPARgamma), a ligand-activated transcription factor, is considered as an anti-osteoblastic factor associated with adiposity and the elderly osteoporosis due to a defect in osteoblastogenesis. We have found that oral administration of PPARgamma activator rosiglitazone decreased tibia BMD and serum ALP but(More)
BACKGROUND This study evaluated the incidence, nature, and seriousness of adverse drug reactions (ADRs) occurring after AdimFlu-S(®) influenza A (H1N1) vaccination in pregnant women was administered. METHODS This is a retrospective cohort study. Between October 2009 and February 2010, 198 pregnant women who had received the AdimFlu-S(®) influenza A (H1N1)(More)
Collagenase-3 (matrix metalloproteinase, MMP-13) plays an important role in the degradation of cartilage in pathologic conditions. MMP-13 is elevated in joint tissues in both rheumatoid arthritis (RA) and osteoarthritis (OA). In addition, inflammation-stimulated synovial fibroblasts are able to release MMP-13 and other cytokines in these diseases. The(More)
The lipoxygenase isoform of 5-lipoxygenase (5-LOX) is reported to be overexpressed in human rheumatoid arthritis synovial tissue and involved in the progress of inflammatory arthritis. However, the detailed mechanism of how 5-lipoxygenase regulates the inflammatory response in arthritis synovial tissue is still unclear. The aim of this study was to(More)
UNLABELLED Dextromethorphan (DXM), a commonly used antitussive, is a dextrorotatory morphinan. Here, we report that DXM inhibits the receptor activator of nuclear factor kappa B ligand (RANKL)-induced osteoclastogenesis and bone resorption by abrogating the activation of NF-κB signalling in vitro. Oral administration of DXM ameliorates ovariectomy(More)
