Data from transgenic mouse models show that neuronal progenitor cells (NPCs) migrate toward experimental brain tumors and modulate the course of pathology. However, the pathways whereby NPCs are attracted to CNS neoplasms are not fully understood and it is unexplored if NPCs migrate toward brain tumors (high-grade astrocytomas) in humans. We analyzed the(More)
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)
The pluripotent mesenchymal stem cells (MSC) are common precursors to adipocytes and osteoblasts. Large numbers of extracellular and intracellular signals and transcription factors moderate adipogenesis and osteoblastogenesis. Importantly, between adipogenic and osteogenic lineage commitment and differentiation, differentiation of MSCs into one lineage will(More)
OBJECTIVE To establish a rat model of bisphosphonate-related osteonecrosis of the jaw (BRONJ) that realistically mimics major clinical manifestations of the disease. METHODS Female Sprague Dawley rats received intravenous zoledronate 80 μg/kg once a week via the tail vein. Three weeks after intravenous injection, maxillary first molars were extracted(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)
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)
Carbon nanotubes (CNTs) find their extensive application as a promising material in medicine due to unique characteristics. However, such materials have been accompanied with potentially hazardous effects on human health. The toxicity of CNTs may vary depending on their structural characteristics, surface properties and chemical composition. To gain insight(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)
Tissue engineering has yielded several successes in early clinical trials of regenerative medicine with grafting therapeutic cells seeded into biodegradable scaffolds. However this conventional cell delivery method has limited the field's progress. In recent decades, we have developed a novel cell transferring method, cell sheet technology that allows for(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)
