STUDY DESIGN Human stromal stem cells derived from menstrual blood (MenSCs) and nucleus pulposus (NP) cells were cocultured under normal or low oxygen (O2) condition. OBJECTIVE To assess the differentiation capability of MenSCs toward nucleus pulposus cells under normal or low oxygen condition. SUMMARY OF BACKGROUND DATA Given the proliferative capacity(More)
Most plant disease-resistance genes (R-genes) isolated so far encode proteins with a nucleotide binding site (NBS) domain and belong to a superfamily. NBS domains related to R-genes show a highly conserved backbone of an amino acid motif, which makes it possible to isolate resistance gene analogues (RGAs) by degenerate primers. Degenerate primers based on(More)
Previous studies have shown that inhibition of prolyl hydroxylase(PHD) stabilizes Hypoxia-inducible factor 1, alpha subunit(HIF-1α), increases tolerance to hypoxia, and improves the prognosis of many diseases. However, the role of PHD inhibitor (PHDI) in the recovery of spinal cord injury remains controversial. In this study, we investigated the protective(More)
OBJECTIVES Tissue engineering is a promising approach for repair of tendon injuries. Adipose-derived mesenchymal stem cells (ADMSCs) have gained increasing research interest for their potential in improving healing and regeneration of injured tendons. The present study aimed to investigate effects of O2 tension and potential signalling pathways on AMDSC(More)
A routing scheme of wireless sensor networks which is suitable for mine monitoring system is designed in this paper. Consideration of the topographic features of coal mine, two-level network is adopted. We design a semi-proactive routing protocol based on tree topology. Isolated nodes in the network send routing requests to neighbor nodes with least path(More)
BACKGROUND Hypoxic conditions play roles in functioning of human tendon-derived stem cells (hTSCs). The goal of this study was to investigate the effect of various hypoxic conditions in self-renewal capacity and differentiation of TSCs. MATERIAL AND METHODS hTSCs was obtain from supraspinatus tendon donors. Colony formation and cell proliferation assay were(More)
OBJECTIVE To review the research progress of different ways of stem cells generation and cells dedifferentiation induced by reversine. METHODS The papers related to reversine inducing cells dedifferentiation and stem cells generation were reviewed. RESULTS To obtain stem cells, there are always some disadvantages via somatic cell nuclear transfer or(More)
BACKGROUND To analyze the relationship between imaging findings and postoperative curative effect by measuring the morphology of the ankle mortise in patients with the Ruedi-Allgouer type III Pilon fractures. MATERIAL AND METHODS Forty-seven patients with Ruedi-Allgouer type III Pilon fractures who underwent surgical treatment from January 2011 to January(More)
PURPOSE We evaluated the feasibility, accuracy and effectiveness of applying three-dimensional (3D) printing technology for preoperative planning for die-punch fractures. METHODS A total of 107 patients who underwent die-punch fracture surgery were enrolled in the study. They were randomly divided into two groups: 52 cases in the 3D model group and 55(More)
