The effects of nitric oxide (NO) in protecting maize (Zea mays) leaves against iron deficiency-induced oxidative stress were investigated. The increased contents of hydrogen peroxide (H(2)O(2)) and superoxide (O(2)(-)*) due to iron deficiency suggested oxidative stress. The increased contents of thiobarbituric acid-reacting substances (TBARS) and the(More)
AIM The process of orthodontic tooth movement (OTM) involves multiple mechanisms of action including bone and extracellular matrix remodelling, although the role of periodontal ligament (PDL) in this process is largely unknown. Periostin, which is highly expressed in the PDL, is known to be responsible for mechanical stimulation in maintaining the integrity(More)
Nucleophosmin (NPM) is a multifunctional protein involved in both proliferation and apoptosis. Importantly, NPM negatively regulates p53 and is frequently overexpressed in a wide variety of cancers. To identify inhibitory molecules of NPM, we used an in vitro selection method termed systematic evolution of ligands by exponential enrichment (SELEX) to select(More)
PURPOSE Overexpression of DJ-1 was associated with metastatic uveal melanoma (UM). The purpose of this study was to evaluate the potential of serum DJ-1 as a biomarker for metastasis of uveal melanoma. METHODS Serum DJ-1 levels were determined by ELISA assays in 27 patients with metastatic UM metastatic uveal melanoma and in 76 patients who were disease(More)
PURPOSE The proteasome inhibitor bortezomib (PS-341) has displayed significant efficiency against pancreatic cancer cells. However, the underlying mechanisms are not fully understood. Here, we tested if ceramide production was involved in the bortezomib's effect. METHODS Two transformed pancreatic cancer cell lines (PANC-1 and Mia) and the primary(More)
OBJECTIVE To test the null hypothesis that there is no effect of maxillary incisor labiolingual inclination and anteroposterior (AP) position on smiling profile esthetics in young adult females. MATERIALS AND METHODS A facial smiling profile photograph of a Chinese woman with a normal profile, a Class I occlusion, and a Class I skeletal pattern was(More)
OBJECTIVE To detect myofibroblast formation on the tension side during orthodontic tooth movement in vivo and myofibroblast expression of alpha-smooth muscle actin (alpha-SMA) induced by tension both in vivo and in vitro. MATERIALS AND METHODS Fifty 6-week male rats were used in this in vivo study, and the right maxillary first molar was moved mesially,(More)
This article reports the successful use of miniscrews in the mandible to treat a 20-year-old Mongolian woman with a chief complaint of anterior crossbite. The patient had a skeletal Class III malocclusion with a mildly protrusive mandible, an anterior crossbite, and a deviated midline. In light of the advantages for reconstruction of the occlusal plane and(More)
α-smooth muscle actin (α-SMA) and tenascin-C are stress-induced phenotypic features of myofibroblasts. The expression levels of these two proteins closely correlate with the extracellular mechanical microenvironment. We investigated how the expression of α-SMA and tenascin-C was altered in the periodontal ligament (PDL) under orthodontic loading to(More)
