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)
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 rhizome of Davallia formosana is commonly used to treat bone disease including bone fracture, arthritis, and osteoporosis in Chinese herbal medicine. Here, we report the effects of WL1101, the ethanol extracts of fresh rhizomes of Davallia formosana on ovariectomy-induced osteoporosis. In addition, excess activated bone-resorbing osteoclasts play(More)
Metabolites from arachidonic acids play the pivotal roles in inflammatory arthritis. Arachidonic acid could be metabolized by cyclooxygenase (COX) and lipoxygenase (LOX) to produce the bioactive eicosanoids. Although the down-stream products of COX including prostaglandin E2 are well-known inflammatory stimulators, the role of LOX products in inflammatory(More)
OBJECTIVE We describe a prenatal molecular diagnosis of hypochondroplasia (HCH) in a pregnancy not at risk of HCH and review the literature on prenatal diagnosis of HCH. CASE REPORT A 28-year-old primigravid woman was referred for genetic counseling at 30 weeks of gestation because of short-limbed dwarfism in the fetus. The woman had a body height of 152(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)
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)
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)
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)
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)
