BACKGROUND MicroRNAs (miRNAs) are a class of small noncoding RNAs that regulate gene expression. They are aberrantly expressed in many types of cancers. In this study, we determined the genome-wide miRNA profiles in bladder urothelial carcinoma by deep sequencing. METHODOLOGY/PRINCIPAL FINDINGS We detected 656 differentially expressed known human miRNAs… (More)
BACKGROUND With the advent of second-generation sequencing, the expression of gene transcripts can be digitally measured with high accuracy. The purpose of this study was to systematically profile the expression of both mRNA and miRNA genes in clear cell renal cell carcinoma (ccRCC) using massively parallel sequencing technology. METHODOLOGY The… (More)
Recently, Zhang et al.  obtained some lower bounds of the signed domination number of a graph. In this paper, we obtain some new lower bounds of the signed domination number of a graph which are sharper than those of them.
In this paper, we derive an explicit formula for the equitable chromatic number of a complete n-partite graph Kp 1 ;p 2 ; ;pn. Namely, if there exists a largest integer M such that pi(mod M) < where e (G) is the equitable chromatic number for graph G.
