A definitive diagnosis of vertical root fracture (VRFs) is often a challenging task for clinicians. Two-dimensional periapical radiographs (PRs) may be not helpful in such a diagnosis when the x-ray beam is not parallel to the plane of the fracture line. This report presents a set of 3 cases in which 1 endodontically treated and 2 nonendodontically treated(More)
BACKGROUND AND OBJECTIVE This study was designed to investigate the p38 mitogen-activated protein kinase (MAPK) signaling pathway involved in Aquaporin1 (AQP1) expression caused by staphylococcal peptidoglycan (PGN) in cultured rat pleural mesothelial cells (rPMCs) in vitro. METHODS RT-PCR and immunoblot analysis were used to determine the relative mRNA(More)
Based on the analysis of current web service applications and protocol, a group of quality of service (QoS) parameters of web traffic is proposed from users' perspective. These parameters focus on delay of web service. A active monitor system is designed and used to monitor web performance on real network of the biggest ISPs in China. These delay parameters(More)
OBJECTIVE To investigate the effect of Notch signaling pathway on human dental pulp cells. METHODS The γ-secretase inhibitor N-[N-(3, 5-difluorophenacetyl-L-alanyl)]-S-phenylglycine t-butyl ester(DAPT) was applied to inhibit the Notch signaling pathway of human dental pulp cells. The solvent dimethly sulfoxide (DMSO) served as the negative(More)
OBJECTIVE To evaluate the effects of Jidesheng anti-venom used externally for skin and soft-tissue necrosis from Chinese cobra bite. METHODS A retrospective review was performed according to the clinical data recorded from January 2002 to December 2012. A total of 126 patients (116 females and 10 males) with skin and soft-tissue necrosis due to Chinese(More)
OBJECTIVE To investigate the expression of stromal cell-derived factor-1 (SDF-1) in human stem cells from apical papilla (SCAP), and to evaluate the effect of lipopolysaccharide (LPS) on SDF-1 expression by SCAP. METHODS SCAP were isolated from dental papilla of human immature third molars. The expression of SDF-1 was evaluated by reverse(More)
