The nanosized titanium dioxide (nano-TiO2) is produced abundantly and used widely in the chemical, electrical/electronic and energy industries because of its special photovoltaic and photocatalytic activities. Past reports have shown that the nano-TiO2 can enter into the human body through different routes such as inhalation, ingestion, dermal penetration(More)
Several studies have reported the adverse effects of nano-CuO on hippocampal CA1 neuron, whereas little has been known about nano-CuO neurotoxicity in vivo. In the present study, we investigated the effects of nano-CuO on spatial cognition and electrophysiological alterations in rats. In addition, histological and biochemical changes in rat's hippocampus(More)
Purpose To retrospectively identify the relationship between epidermal growth factor receptor (EGFR) mutation status, predominant histologic subtype, and computed tomographic (CT) characteristics in surgically resected lung adenocarcinomas in a cohort of Asian patients. materials and Methods This study was approved by the institutional review board, with(More)
Nanosized copper particles (nano-Cu), one of the representative metal nanometer materials, were used in several domains, and the potential toxicity was raised more and more attention. In order to investigate the cytotoxicity induced by nano-Cu in podocytes, which was the key player of the glomerular filtration barrier, podocytes were treated with different(More)
Glutamate, one of the major neurotransmitters in the central nervous system, is released into the synaptic spaces and bound to the glutamate receptors which facilitate normal synaptic transmission, synaptic plasticity, and brain development. Past studies have shown that glutamate with high concentration is a potent neurotoxin capable of destroying neurons(More)
This study investigated effects of trifluoperazine (TFP) against the cytotoxicity induced by H₂O₂ in PC12 cells and the mechanisms thereof. Different concentrations of H₂O₂ (100-500 μM) induced a significant decrease in cell viability accompanied by increased oxidative stress and cell apoptosis. Pretreatment with TFP inhibited H₂O₂-induced cell viability(More)
Remifentanil is a kind of synthetic opioid which has gained wide clinical acceptance by anesthesiologists. In this study, we attempted to test whether withdrawal effects on learning mechanisms can be triggered by repeated low-dose remifentanil treatment. Male Sprague-Dawley (SD) rats were subjected to remifentanil (50μg/kgs.c.) twice per day at 12h(More)
The aim of this study was to investigate the effects of nano-CuO on voltage-gated sodium current (I(Na) ) in hippocampal CA1 neurons. The results suggested that nano-CuO inhibited amplitudes of I(Na) currents and prolonged peak rise time of action potential (AP). The responses to nano-CuO were inhibited by reactive oxygen species (ROS) scavenger. However,(More)
Site-specific chemical cross-linking in combination with mass spectrometry analysis has emerged as a powerful proteomic approach for studying the three-dimensional structure of protein complexes and in mapping protein-protein interactions (PPIs). Building on the success of MS analysis of in vitro cross-linked proteins, which has been widely used to(More)
Flexible sensors have attracted more and more attention as a fundamental part of anthropomorphic robot research, medical diagnosis and physical health monitoring. Here, we constructed an ultrasensitive and passive flexible sensor with the advantages of low cost, lightness and wearability, electric safety and reliability. The fundamental mechanism of the(More)
