The differentiation of adipose tissue-derived stromal cells (ADSCs) into adipocytes involves a highly orchestrated series of events that includes cell lineage commitment, mitotic clonal expansion, growth arrest, and terminal differentiation. However, the molecular mechanisms controlling adipogenesis are not yet completely understood. In this study, we(More)
Mechanical stress is a well-acknowledged positive regulatory factor for osteogenic differentiation of adipose- derived mesenchymal stem cells (ADSCs). However, the molecular mechanisms associated with micro-RNAs (miRNAs) whereby ADSCs respond to mechanical stimuli remain elusive. We investigated the mechanism of mechanotransduction from the miRNA(More)
PDLSC-mediated periodontal tissue regeneration is considered a promising method for periodontitis treatment, but the supply of PDLSCs is limited. As a potential alternative, WJCMSCs are readily available; however, there is a lack of evidence proving that WJCMSCs are suitable for periodontal tissue regeneration. In this study, we investigated the(More)
The high absorption rate of transplanted fat has limited the application of autogenous fat grafts in the clinical setting. Therefore, this study aimed to evaluate the effects of platelet-rich plasma (PRP) and adipose-derived stem cells (ASCs) on fat regeneration by investigating the impact of PRP and conditioned medium on the biological characteristics of(More)
OBJECTIVE Distraction osteogenesis typically requires a long treatment period, which can lead to bone and soft-tissue infection and considerable patient discomfort. Use of a rapid distraction rate in craniofacial distraction osteogenesis to shorten the distraction period is possible owing to the unique characteristics of craniofacial bones, including an(More)
OBJECTIVE The purpose of this retrospective study was to investigate the diagnostic methods, therapeutic principles, surgical approach, and materials used for orbital floor reconstruction. STUDY DESIGN This study consisted of 21 cases with orbital fractures treated at the Hospital of Stomatology, Sichuan University, China, between July 2002 and June 2006.(More)
INTRODUCTION Superolateral dislocation of the mandibular condyle (SDMC) is rarely described. The best treatment for superolateral dislocation of the fractured mandibular condyle (SDMC) is debated. This study investigated selection of the timing and techniques used in treating these fractures. PATIENTS AND METHODS A retrospective clinical study was(More)
PURPOSE To introduce a new surgical approach for open reduction and internal fixation of condylar fracture. PATIENTS AND METHODS In this study, 36 patients with condylar fractures (51 sides) and those of the mandibular ramus and coronoid process were treated using a modified retromandibular approach indirectly from the anterior edge of the parotid gland.(More)
A completely integrated 2.4GHz low-power low-phase-noise voltage-controlled oscillator (VCO) was implemented in a standard 0.18/spl mu/m CMOS single-poly, 6-metal mixed-signal CMOS process. The VCO-core draws 1.5mA of current from a 1.2V supply. Comparison shows that this design has better performance than previously published similar results.
The differentially expressed in adenocarcinoma of the lung-1 (DAL-1) protein is a member of the membrane-associated cytoskeleton protein 4.1 family. This protein was previously found to be downregulated or lost in more than half of primary non-small cell lung cancers (NSCLC). In this study, the relationship between DAL-1 expression and NSCLC metastasis was(More)
