To investigate the effects of sodium fluoride (NaF) on apoptosis, c-Fos mRNA and protein expression levels, and methylation status as well as Dnmt1, Dnmt3a, and Dnmt3b mRNA expression levels in human embryo hepatocyte (L-02) which were exposed to different concentrations of NaF (0, 20, 40, and 80 mg/l) for 24 h in vitro. Results showed that the percentage(More)
An essential aspect of tooth tissue engineering is the identification of suitable scaffolding materials to support cell growth and tissue regeneration. Treated dentin matrix (TDM) from a rat has recently been shown to be a suitable scaffold for rat dentin regeneration. However, due to species-specific differences, it remains unclear whether a similar(More)
BACKGROUND The risk of VTE before anticancer therapy in patients with lung cancer is not well defined. METHODS A total of 673 hospitalized patients with newly diagnosed lung cancer were examined for VTE within 1 week after admission at five hospitals between January 2009 and January 2011. Additionally, VTE diagnoses within the last 3 months were reviewed.(More)
The mechanisms underlying the neurotoxicology of endemic fluorosis still remain obscure. To explore lactate dehydrogenase (LDH) leakage, intracellular Ca²⁺ concentration ([Ca²⁺]i ) and reactive oxygen species (ROS) production induced by fluoride, human neuroblastoma (SH-SY5Y) cells were incubated with sodium fluoride (NaF, 20, 40, 80 mg/L) for 24 h, with 40(More)
Polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are widespread environmental contaminants. There are potential interactive effects between PBDEs and PCBs, as these compounds share similar structures. The developmental neurotoxicity of 2, 2', 4, 4'-tetrabromodiphenyl ether (PBDE-47) and the interaction of PBDE-47 with 2, 2', 4,(More)
OBJECTIVE MicroRNA-21 (miR-21) has been shown to be a key regulator of carcinogenesis. There were few reports about the comparison of serum miR-21 with conventional tumor markers. This study aimed to explore the diagnostic value of circulating miR-21 as a tumor marker in breast cancer (BC) and compare it with CA153 and carcinoembryonic antigen (CEA). (More)
OBJECTIVE The indications for temporomandibular joint (TMJ) reconstruction are well established, but the method of reconstruction is controversial. The purpose of this retrospective study was to compare individual prefabricated condyle implants and costochondral grafts in condyle reconstruction after tumor resection. STUDY DESIGN We conducted a(More)
Calpains are calcium-regulated proteases involved in cellular functions that include muscle proteolysis both ante- and post-mortem. This study was designed to clone the complete coding sequence of the porcine calpain10 gene, CAPN10, to analyze its expression characteristics and to investigate its polymorphism. Two isoforms of the CAPN10 gene, CAPN10A and(More)
OBJECTIVE To analyze retrospectively 419 patients after the Wenchuan earthquake and 46 after Yushu earthquake with maxillofacial fractures so as to provide reference on patients' treatment after an earthquake. METHOD We investigated 419 patients after Wenchuan earthquake and 46 after Yushu earthquake with maxillofacial fractures who were admitted to the(More)
The mechanisms underlying fluoride-induced apoptosis in neurons still remain unknown. To investigate apoptosis, caspase-3 activity, and mRNA expression of Fas, Fas-L, and caspases (-3 and -8) induced by fluoride, human neuroblastoma (SH-SY5Y) cells were incubated with 0, 20, 40, and 80 mg/L sodium fluoride (NaF) for 24 h in vitro. The data show that cell(More)
