Budesonide and Calcitriol Synergistically Inhibit Airway Remodeling in Asthmatic Mice

Background and Objective. While calcitriol can inhibit airway remodeling in asthmatic mice, the mechanism remains unclear. The purpose of this study was to explore the mechanism of action of calcitriol on airway remodeling in asthma and its interaction with budesonide. Methods. A mouse model of asthma was established by allergic sensitization and challenge with ovalbumin. The...

Elevated mean platelet volume predicts poor prognosis in colorectal cancer

Altered mean platelet volume (MPV) is implicated in several malignancies. However, the clinicopathological significance and prognostic value of MPV in colorectal cancer (CRC) is still elusive. The purpose of this study was to elucidate the predictive significance of MPV in CRC. The retrospective study recruited 509 consecutive CRC patients between January 2009 and December 2009...

Dimension Estimation Using Weighted Correlation Dimension Method

Dimension reduction is an important tool for feature extraction and has been widely used in many fields including image processing, discrete-time systems, and fault diagnosis. As a key parameter of the dimension reduction, intrinsic dimension represents the smallest number of variables which is used to describe a complete dataset. Among all the dimension estimation methods...

Dechao Geng Zhiwei Yu Shengguang Zhang Wenzhong Wang Yuan-Zhong Hu Hui Wang Jianbin Luo Superlubricity of graphite and graphene has aroused increasing interest in recent years. Yet how to obtain a long

D-Optimal Design for Parameter Estimation in Discrete-Time Nonlinear Dynamic Systems

An optimal input design method for parameter estimation in a discrete-time nonlinear system is presented in the paper to improve the observability and identification precision of model parameters. Determinant of the information matrix is used as the criterion function which is generally a nonconvex function about the input signals to be designed. To avoid the locally optimizing...
