MicroRNAs were recently found to participate in oncogenesis and growth of various tumors. We hypothesized that microRNA-223 (miR-223) plays a role in endometrial carcinoma growth. In this study, we transfected RL95-2 cells with lentivirus containing miR-223 precursor to establish a miR-223 over-expression model. Proliferation of the cells was greatly(More)
MicroRNA (miRNA) regulates gene expression in a post-transcriptional manner, which hybridizes the target mRNAs with complementary sequence and subsequently leads to translation repression or mRNA degradation. Online sequence alignment showed that there is a putative binding site of miR-223-3p on the 3'UTR of LIF, which is considered to be an important(More)
Inorganic non-metallic biomaterials, including the silicon frustule of a unicellular diatom, the carbonate shell of a mollusk and the calcium skeleton of the vertebrate, which are the main constituent part of an organism, serve as the supportive and protective components of soft tissue. Among them, hydroxyapatite, which primarily makes up the enamel and(More)
Financial contagion problems have been extensively studied in area of financial research. Most of the works focus on studying the contagion effect on the financial system. Contagion prediction is considered as one of the most important strategies to prevent contagion. But the prediction issue is seldom researched in the financial area. Traditional financial(More)
In this paper, Value at Risk of hedging portfolio is adopted to measure the risk of futures hedging. The control constraint based on risk tolerance of hedgers is established. The futures optimal hedge ratio is presented by maximizing the return of hedging portfolio under the control constraint. The contributions of the model are as follows: Firstly that we(More)
OBJECTIVE Our study is aimed to explore effects of five treatment regimens on blood loss and blood transfusion rate in total knee arthroplasty (TKA) patients. METHODS 191 TKA patients were divided into the rivaroxaban, nadroparin, and tranexamic acid groups (n = 37 each) as well as into the affected-limb-position and tourniquet group (n = 40 each). A(More)
This paper takes the lending rate as the output parameter of DEA and establishes the loan pricing model based on DEA by using the dichotomy to solve the corresponding output parameters under the optimal efficiency of DEA. Its specialties and innovations are as follows. Firstly, the corresponding output parameter of DEA, the lending rate, is determined when(More)
