OBJECTIVE To explore the expression of B7 co-stimulator in human malignant hematological cell lines and its significance. METHODS Amplified and purified plasmid DNA was transfected by liposome and detection of B7 gene expression by flow cytometry and RT-PCR. RESULT Eight human malignant hematological cell lines U937, K562, CEM, Daudi, GM, PEER, Jurkat,(More)
OBJECTIVE To explore the effects of a novel human chemokine-like factor 1 (CKLF1) on stem cell/progenitor cells. METHODS Human bone marrow mononuclear cells were separated by Ficoll (1.077 g/ml), and cultured in suspension and semisolid colony culture. The effects of CKLF1 on CFU-GM and CFU-Mix were observed. RESULTS The number of CFU-GM was(More)
In order to elucidate the role of HPV-16 in the development of genital cancer, NIH3T3 cells were transfected by HPV-16 whole genome and its two early genes, E6-E7. Besides ordinary calcium phosphate/DNA coprecipitation technique, a newly designed recombinant retrovirus containing the HPV-16 genome or subgenomes was used to infect cells for transfer of the(More)
Recent years, a variety of infrastructure-mediated sensing methods have been proposed to recognize activities of daily living (ADLs). However, due to the inconvenience such as high-cost, difficult-to-install, intrusive and applicable to the house with specific architectures alone, existing water-use activity recognition methods cannot be widely used into(More)
Nonlinear constrained problem has been deemed as a hard problem. This paper proposes a kind of evolutionary algorithm for constrained programming. The constrained conditions are converted into an objective and then the constrained programming is transformed into a special bi-objective unconstrained problem. The Pareto concept of multiobjective programming(More)
In this paper, improved Logistic models are given, which are called Logarithm Logistic Models. Based on U.S. Census data, the parameters of the models were estimated by applying the Least Squares Method. The experiments show that the prediction value of the new models is much closer to the actual value than the classical Logistic model. Finally, through(More)
Multiobjective bilevel linear programming is a decentralized decision problem, it consists of many objectives at the upper level and the lower level, respectively. It has a wide field of applications and has been proven to be NP-hard. In this paper, a kind of multiobjective bilevel convex programming(MBCP) is studied, in which the lower level is first(More)
Elevated CARMA3 expression has been reported to be involved in tumor progression of several cancer types. In the present study, we examined the expression pattern of CARMA3 protein and its biological roles in human pancreatic carcinoma. Using immunohistochemistry, we checked CARMA3 protein expression in 95 pancreatic ductal carcinoma specimens. We found(More)
