PURPOSE To relate lung dose-volume histogram-based factors to symptomatic radiation pneumonitis (RP) in patients with lung cancer undergoing 3-dimensional (3D) radiotherapy planning. METHODS AND MATERIALS Between 1991 and 1999, 318 patients with lung cancer received external beam radiotherapy (RT) with 3D planning tools at Duke University Medical Center.(More)
The current study aimed to prove that human dental pulp stem cells (hDPSCs) isolated from the pulp of third molars can show multilineage differentiation after cryopreservation. First, hDPSC were isolated via enzymatic procedures, and frozen in liquid nitrogen until use. After defrosting, cells were analyzed for proliferative potential and the expression of(More)
BACKGROUND The Wenchuan earthquake was a catastrophic earthquake in China. The aim of this study is to explore longitudinally the rates of post-traumatic stress disorder (PTSD) and depression in adolescents after the Wenchuan earthquake, and to identify independent predictors of PTSD. METHOD PTSD and depression symptoms among adolescents at 6, 12 and 18(More)
BACKGROUND Oral lichen planus (OLP) is a chronic inflammatory disease with different clinical presentations that can be classified as reticular, atrophic or erosive. Although OLP is a relatively common disorder, the reports comprising large numbers of OLP patients with specific character are lacking in the literature. The purpose of this paper was to(More)
The purpose of this study was to evaluate the effects of sodium hypochlorite (5.25%), chlorhexidine (2%), and Glyde File Prep on the bond strengths of MTA-dentin in vitro. Standardized dentin disks were prepared and the central hole in each disk was filled with mineral trioxide aggregate (MTA). The specimens were randomly divided into four groups to be(More)
BACKGROUND Dentin phosphoprotein (DPP) is the most abundant non-collagenous protein in dentin, which is highly phosphorylated and plays key roles in dentin biomineralization. The aetiology of isolated hereditary dentin disorders in most affected families is largely unknown and the association between DPP and dentin disorders has not been well established.(More)
The purpose of this study was to investigate the morphology of the radicular grooves and root canal cross-sections in mandibular first premolars that exhibit a C-shaped root. Eighty-six mandibular first premolars with C-shaped roots were scanned from the coronal to anatomical apex using microCT80. The location, length, and depth of the radicular grooves(More)
BACKGROUND AND PURPOSE Decreased oxygen supply may cause neuronal damage in the brains of patients with COPD, which is manifested by clinical symptoms such as neuropsychological deficits and mood disorders. The aim of the present study was to investigate brain gray matter change in COPD. MATERIALS AND METHODS Using voxel-based morphometry based on the(More)
OBJECTIVE To describe oral health status of urban Chinese children aged 12 years, to evaluate the pattern of oral health behaviour, and to assess the relative effect of socio-behavioural risk factors on dental caries experience. DESIGN A cross-sectional survey of 12-year-old children was conducted in the Hubei Province of China, including urban and(More)
OBJECTIVES To assess oral health outcomes of a school-based oral health education (OHE) programme on children, mothers and schoolteachers in China, and to evaluate the methods applied and materials used. DESIGN The WHO Health Promoting Schools Project applied to primary schoolchildren in 3 experimental and 3 control schools in Hongshan District, Wuhan(More)
