Bone marrow-derived mesenchymal stem cells (BMSCs, also known as bone marrow-derived mesenchymal stromal cells) are known to be a component of the tumor microenvironment. BMSCs are multipotent stromal cells that can differentiate into a variety of cell types, including osteocytes, chondrocytes, adipocytes, epithelial cells and endothelial cells. Stem cells(More)
Brainstem dose limitations influence radiation dose reaching to tumor in the patients with locally-advanced nasopharyngeal cancer (NPC). A retrospective analysis of the prognostic value of the distance between the primary tumor and brainstem (Dbs) in 358 patients with locally-advanced NPC after intensity-modulated radiation therapy (IMRT). Receiver(More)
Cancer dormancy is a stage in tumor progression in which residual disease remains occult and asymptomatic for a prolonged period. Cancer cell dormancy is the main cause of cancer recurrence and failure of therapy. However, cancer dormancy is poorly characterized and the mechanisms of how cancer cells develop dormancy and relapse remain elusive. In this(More)
OBJECTIVE To detect of chromosomal abnormalities in multiple myeloma (MM) patients with fluorescence in situ hybridization (FISH). METHODS FISH was performed in 20 MM patients using 5 specific DNA probes. The difference in chromosomal abnormalities was compared by FISH and other routine cytogenetic tests. RESULTS Eighteen of the 20 patients showed(More)
The endoplasmic reticulum (ER) is an essential organelle that spreads throughout the cytoplasm as one interconnected network of narrow tubules and dilated cisternae that enclose a single lumen. The ER network undergoes extensive remodeling, which critically depends on membrane-cytoskeleton interactions [1]. In plants, the ER is also highly mobile, and its(More)
BACKGROUND Epstein Barr virus (EBV) plays a causal role in some diseases, including infectious mononucleosis, lymphoproliferative diseases and nasopharyngeal carcinoma. Detection of EBV infection has been shown to be a useful tool for diagnosing EBV-related diseases. In the present study, we compared the performance of molecular tests, including(More)
Tensegrity traced back to the early 20's, the characteristics of the structure are potentially extensive applications in geometry and mechanics. In 2015 NASA researched out a tensegrity robot called SUPPERBall. This robot has been greatly improved compared to the previous tensigrity robot. However, they just focused on the design of the space structure of(More)
OBJECTIVE To detect chromosomal abnormalities in myelodysplastic syndrome (MDS) patients by fluorescence in situ hybridization (FISH) and conventional cytogenetic analysis (CCA). METHODS FISH and CCA were performed in 100 patients who were diagnosed with MDS by conventional detection of bone marrow smear and bone marrow biopsy, and were followed up. (More)
OBJECTIVE To investigate several abnormal genes by the fluorescence in situ hybridization (FISH) in multiple myeloma (MM), monoclonal gammopathy of undetermined significance (MGUS) and reactive plasmacytosis (RP), and to increase the diagnosis and differential diagnosis levels for these common plasma diseases. 
 METHODS The clinical manifestations, image(More)
In this paper, the problem of time-optimal path tracking is investigated for coordinated dual-robot system. In the case of dual-robot system carrying on coordinated manipulation process with simplified physical constraints, a sequential convex programming (SCP) framework is implemented to realize time optimality. Moreover, versatile optimization objective(More)
