Multimodal hashing is essential to cross-media similarity search for its low storage cost and fast query speed. Most existing multimodal hashing methods embedded heterogeneous data into a common low-dimensional Hamming space, and then rounded the continuous embeddings to obtain the binary codes. Yet they usually neglect the inherent discrete nature of(More)
OBJECTIVE The prediction of operons is critical to the reconstruction of regulatory networks at the whole genome level. Multiple genome features have been used for predicting operons. However, multiple genome features are usually dealt with using only single method in the literatures. The aim of this paper is to develop a combined method for operon(More)
As is well known, nonnegative matrix factorization (NMF) is a popular nonnegative dimensionality reduction method which has been widely used in computer vision, document clustering, and image analysis. However, traditional NMF is an unsupervised learning mode which cannot fully utilize the priori or supervised information. To this end, semi-supervised NMF(More)
OBJECTIVE To study the relationship between esophageal cancer (EC) and the ingestion of folate, methylenetetrahydrofolate reductase (MTHFR) C677T gene polymorphisms in Kazakh area, Xinjiang. METHODS A 1:2 matched case-control study was adopted. 120 cases diagnosed as esophageal cancer were collected with 240 population-based and hospital-based controls(More)
MicroRNAs (miRNAs) are involved in the fine control of cell proliferation and differentiation during the development of the nervous system. MiR-124, a neural specific miRNA, is expressed from the beginning of eye development in Xenopus, and has been shown to repress cell proliferation in the optic cup, however, its role at earlier developmental stages is(More)
In chondrocytes, PTHrP maintains them in a proliferative state and prevents premature hypertrophy. The mechanism by which PTHrP does this is not fully understood. Both Runx2 and Runx3 are required for chondrocyte maturation. We recently demonstrated that cyclin D1 induces Runx2 protein phosphorylation and degradation. In the present studies, we tested the(More)
A class of self-assembling peptide nanofiber scaffolds has been shown to be an excellent biological material for 3-dimension cell culture and stimulating cell migration into the scaffold, as well as for repairing tissue defects in animals. We report here the development of several peptide nanofiber scaffolds designed specifically for osteoblasts. We(More)
Nobiletin (NOB), the major bioactive component of polymethoxyflavones in citrus fruits, has been reported possessing significant biological properties. The purpose of the present study was to investigate the protective role of NOB on lipopolysaccharide (LPS)-induced endotoxic shock in mice. We found pretreatment with NOB increases the survival rate of mice(More)
Runx2 is a Runt domain transcription factor involved in the activation of genes encoding osteoblast and chondrocyte-specific proteins. Runx2 activity is regulated by transcriptional and post-transcriptional mechanisms. The functional significance of the post-translational modification of Runx2 has not been fully defined. We show that cyclin D1-Cdk4 induce(More)
Ulcerative colitis is an inflammatory disorder characterized by neutrophils infiltration, oxidative stress, upregulation of pro-inflammatory mediators and cytokines. Cavidine possesses anti-inflammatory activity and has been used to treat various inflammatory diseases but its effect on ulcerative colitis has not been previously explored. The present study(More)
