The developing murine tooth has been used as an excellent model system to study the molecular mechanism of organ development and regeneration. While the expression patterns of numerous regulatory genes have been examined and their roles have begun to be revealed in the developing murine tooth, little is known about gene expression and function in human(More)
The WNT/β-CATENIN signaling has been demonstrated to play critical roles in mouse tooth development, but little is known about the status of these molecules in human embryonic tooth. In this study, expression patterns of WNT/β-CATENIN signaling components, including WNT ligands (WNT3, WNT5A), receptors (FZD4, FZD6, LRP5), transducers (β-CATENIN),(More)
The demand for orthopedic and dental implants will continue to grow, and for these applications, titanium and its alloys have been used extensively. While these implants have achieved high success rates, two major complications may be encountered: the lack of bone tissue integration and implant-centered infection. The surface of the implant, through its(More)
OBJECTIVE To investigate the effect of Alismatis rhizome (AR) extract on lipid profile in mice fed high-fat diet. METHODS The study was performed in Key Laboratory of Chinese Medicine Resource and Compound Prescription (Hubei University of Chinese Medicine), Ministry of Education, Wuhan, China, between December 2009 and June 2010. Forty male Kunming mice(More)
Direct current (DC) stimulation has been used to promote bone repair and osteogenesis, but problems associated with the implanted metal electrodes may limit its application and compromise the therapeutic results. The replacement of the metal electrodes with a biodegradable conductive polymer film can potentially overcome these problems. In our work,(More)
This paper presents a robust and efficient method for license plate detection with the purpose of accurately localizing vehicle license plates from complex scenes in real time. A simple yet effective image downscaling method is first proposed to substantially accelerate license plate localization without sacrificing detection performance compared with that(More)
Toxicity of engineered nanoparticles on organisms is of concern worldwide due to their extensive use and unique properties. The impacts of ZnO nanoparticles (ZnO NPs) on seed germination and root elongation of corn (Zea mays L.) and cucumber (Cucumis sativus L.) were investigated in this study. The role of seed coats of corn in the mitigation toxicity of(More)
The homeodomain transcription factor Shox2 plays a crucial regulatory role in the development of sinoatrial node (SAN) by repressing the expression of Nkx2.5, as demonstrated by failed differentiation of SAN in Shox2 null mice. The SHOX (short stature homeobox) gene family consists of two closely related members, SHOX and SHOX2 in humans, but a SHOX(More)
Embryonic development is a tightly regulated process, and many families of genes functions to provide a regulatory genetic network to achieve such a program. The homeobox genes are an extensive family that encodes transcription factors with a characteristic 60-amino acid homeodomain. Mutations in these genes or in the encoded proteins might result in(More)
Mammalian tooth development is regulated by paracrine signal molecules of several conserved family interactions between epithelium and mesenchyme. The expression patterns and regulative roles of FGF signaling have been extensively studied in the mouse odontogenesis; however, that is not well known in human tooth development. In order to unveil the molecular(More)
