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)
Primarily this report outlines our investigation on utilizing magneto-acousto-electrical-tomography (MAET) to image the lead field current density in volume conductors. A lead field current density distribution is obtained when a current/voltage source is applied to a sample via a pair of electrodes. This is the first time a high-spatial-resolution image of(More)
Cartilage has poor ability of spontaneous repair. Traditional treatments such as microfracture, bone drilling and autologous osteochondral graft were not fully satisfactory to fulfill the clinical needs. The idea of mesenchymal stem cell (MSCs-based cartilage regeneration has been put forward for decades. Large number of studies have been conducted on the(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)
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)
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)
Diffusive gradients in thin films (DGT) technique was used to determine pore water profile and to assess remobilization character of metals at sediment/water interface. The remobilization of Mn was due to redox reaction in profile, which engendered two large peaks: one with DGT concentration of 1355 µg L(-1) at depth of -4.75 cm in sediment and the other(More)
BACKGROUND The viability of periodontal ligament fibroblasts (PDLF) can affect the long-term prognosis of replanted avulsed teeth. When immediate replantation of an avulsed tooth is not possible, the cells should be incubated in a physiological storage medium instantly to maintain their biological activity. The ability of different storage media to preserve(More)
