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)
BACKGROUND The human apurinic/apyrimidinic endonuclease 1/Redox effector factor-1 (APE1/Ref-1) is implicated in tumor development and progression. Recently, the APE1/Ref-1 promoter -141T/G variant (rs1760944) has been reported to be associated with lung cancer risk. Given the importance of APE1/Ref-1 in both DNA repair and redox activity, we speculate that(More)
Fluorine, a toxic and reactive element, is widely prevalent throughout the environment and can induce toxicity when absorbed into the body. This study was to explore the possible mechanisms of developmental neurotoxicity in rats treated with different levels of sodium fluoride (NaF). The rats’ intelligence, as well as changes in neuronal morphology, glucose(More)
Interleukin-1α and interleukin-1β aggravate neuronal injury by mediating the inflammatory reaction following ischemic/hypoxic brain injury. It remains unclear whether interleukin-1α and interleukin-1β are released by microglia or astrocytes. This study prepared hippocampal slices that were subsequently subjected to oxygen and glucose deprivation.(More)
One-carbon metabolism facilitates the cross-talk between genetic and epigenetic processes, making it a good candidate for studying the risk of lung cancer. To investigate the role of common variants of one-carbon metabolizing genes on lung cancer risk, total 25 single nucleotide polymorphisms (SNPs) in 7 genes were genotyped among 500 incident lung cancer(More)
INTRODUCTION Resting-state functional magnetic resonance imaging (fMRI) has been used to examine the brain mechanisms of stroke patients with hemiplegia, but the relationship between functional connectivity (FC) and treatment-induced motor function recovery has not yet been fully investigated. This study aimed to identify the brain FC changes in stroke(More)
We hypothesized that the P2X7 receptor may be the target of isoflurane, so we investigated the roles of the P2X7 receptor and inositol triphosphate receptor in calcium overload and neuronal apoptosis induced by isoflurane in cultured embryonic rat hippocampal neurons. Results showed that isoflurane induced widespread neuronal apoptosis and significantly(More)
PURPOSE N-methyl-D-aspartate (NMDA) receptors in the prefrontal cortex (PFC) are closely related with the excitability of pyramidal neurons and PFC function. As the effect of thiopental sodium on the central nervous system may partly result from the inhibition of PFC NMDA receptors, we investigated the effect of thiopental sodium with different(More)
We present a novel platform for the development and deployment of nanosensors in integrated systems. The nanosensor technology is based on ''striped'' high aspect ratio cylindrical structures grown using porous membranes as templates. These nanostructures are manipulated using dielectrophoretic forces, allowing their individual assembly and(More)
Ionizing radiation is known to cause DNA damage, including single-strand and double-strand DNA breaks (DSBs), and the unrepair of DNA damage, particularly DSBs, may cause chromosome aberrations. Although the etiology of gliomas remains unclear, exposure to ionizing radiation has been identified as the only established risk factor. We hypothesized that(More)
