Graphene quantum dots (GQD) generate intrinsic fluorescence, and improves aqueous stability of graphene oxide (GO) while maintaining wide chemical adaptability and high adsorption capacity. Despite GO's remarkable advantages in bio-imaging, bio-sensing and other biomedical applications, its biosafety issues are still unclear. Here we report a detailed and(More)
Phase transition phenomena between non-congested and congested phases in packet traffic have been observed in many packet switching networks (PSNs). Using the PSN model we investigate the nature of fluctuations in number of packets in transit from their source to their destination, when the mean flow density into the PSN model is close to the phase(More)
BACKGROUND & AIMS Many colorectal cancer (CRC) cells contain mutations in KRAS. Analyses of CRC cells with mutations in APC or CTNNB1 and KRAS identified SLC25A22, which encodes mitochondrial glutamate transporter, as a synthetic lethal gene. We investigated the functions of SLC25A22 in CRC cells with mutations in KRAS. METHODS We measured levels of(More)
DIM (3,3'-diindolylmethane), a small molecule compound, is a proposed cancer preventive agent that can be safely administered to humans in repeated doses. We report that administration of DIM in a multidose schedule protected rodents against lethal doses of total body irradiation up to 13 Gy, whether DIM dosing was initiated before or up to 24 h after(More)
OBJECTIVE Tranexamic acid (TA), a synthetic antifibrinolytic drug, has been shown to reduce postoperative bleeding and the need for allogeneic blood transfusion in cardiac surgery. However, the optimal dose regimen of TA is still under debate. The aim of this study was to evaluate whether a lower-dose TA regimen produced equivalent efficacy to its(More)
BACKGROUND With a wide range of applications, titanium dioxide (TiO₂) nanoparticles (NPs) are manufactured worldwide in large quantities. Recently, in the field of nanomedicine, intravenous injection of TiO₂ nanoparticulate carriers directly into the bloodstream has raised public concerns on their toxicity to humans. METHODS In this study, mice were(More)
BACKGROUND The residents' knowledge, attitudes and practices related to ambient air pollution and health will help to improve the understanding of environmental protection and make environmental health policies more targeted and effective. This study aimed at knowing the attitudes and behaviors towards ambient air pollution and health. METHODS A(More)
Antiproliferative gene B-cell translocation gene, member 2 (BTG2) is a member of the BTG/TOB antiproliferative gene family. In this study, we investigated the effect of BTG2 gene overexpression on the radiosensitivity of breast cancer cells in vitro and in vivo. Results show that in human breast cancer cell line MCF-7 stably overexpressing BTG2 gene, cell(More)
Resistin is an adipokine secreted from adipose tissue, which is likely involved in the development of obesity and insulin resistance via its interaction with other organs, as well as affecting adipose tissue function. The impact of resistin treatment on lipolysis and adiponectin secretion in human visceral adipose tissue is currently unknown. Mesenteric(More)
