UNLABELLED Our research aimed to look into the clinical traits and genetic mutations in sporadic non-syndromic anodontia and to gain insight into the role of mutations of PAX9, MSX1, AXIN2 and EDA in anodontia phenotypes, especially for the PAX9. MATERIAL AND METHODS The female proband and her family members from the ethnic Han families underwent complete(More)
This study aimed to assess generic health-related quality of life (HRQoL), pain intensity, and anxiety levels and the relationship between the three aspects in healthy young Chinese orthodontic patients in the early stage of orthodontic treatment. We enrolled 252 eligible participants (10-29 years old) to complete validated Chinese versions of(More)
Guided bone regeneration (GBR) is a principle adopted from guided tissue regeneration (GTR). Wherein, GBR is used for the healing of peri-implant bony dehiscences, for the immediate placement of implants into extraction sockets and for the augmentation of atrophic alveolar ridges. This procedure is done by the placement of a resorbable or non-resorbable(More)
Hypodontia is caused by interactions among genetic, epigenetic, and environmental factors during tooth development, but the actual mechanism is unknown. DNA methylation now appears to play a significant role in abnormal developments, flawed phenotypes, and acquired diseases. Methylated DNA immunoprecipitation (MeDIP) has been developed as a new method of(More)
Previous studies evaluating the association between the XPG Asp1104His polymorphism and melanoma susceptibility remained controversial. To draw a more precise estimation of the relationship, a total of eight published case–control studies containing 5,212 cases and 7,045 controls were included for meta-analysis. Overall, a significant association was found(More)
In this paper, a new bond graph method (BGM) model to describe the thin-walled elastic tube with the inviscid compressible fluid is presented. This model represents an improvement over the classical BGM model because the fluid-structure interaction, which acts an important pole in the modal analysis of the pipe with fluid, is considered in this model. The(More)
Glioma is the most common and malignant brain tumor with extremely poor prognosis. It is crucial to understand the molecular characteristics of glioma and find out more effective therapeutic targets for the treatment of glioma. USP17 is a novel deubiquitinating enzyme that is differentially expressed in certain types of solid tumor. Our present study(More)
The present work studies the pulsation attenuation characteristics of expansion chamber. First, the work principle of expansion chamber is studied. Then, the flow fields of expansion chambers with different sizes are simulated with CFD simulation software. In addition, analyze in detail the relationship between the pulsation attenuation characteristics of(More)
