Recently, the Intel Xeon Phi coprocessor has received increasing attention in high performance computing due to its simple programming model and highly parallel architecture. In this paper, we implement sparse matrix vector multiplication (SpMV) for scale-free matrices on the Xeon Phi architecture and optimize its performance. Scale-free sparse matrices are(More)
Several studies showed that the genetic mutations in the folate-related enzyme genes might be associated with male infertility; however, the results were still inconsistent. We performed a meta-analysis with trial sequential analysis to investigate the associations between the MTHFR C677T, MTHFR A1298C, MTR A2756G, MTRR A66G mutations and the MTHFR(More)
Deciphering <i>cis</i>-regulatory networks has become an attractive yet challenging task. This paper presents a simple model for <i>cis</i>-regulatory network discovery which aims to avoid most of the common problems of previous approaches. Using promoter sequences and gene co-expression profiles as input, rather than clustering the genes by the(More)
BACKGROUND The RhoA/ROCK pathway and Caveolin-1 (Cav-1) participate in the process of tumorigenesis in numerous types of cancer. Up-regulation of RhoA/ROCK and Cav-1 expression is considered to be associated with the development and progression of clear cell renal cell carcinoma (ccRCC). We investigated the association between genetic variations of(More)
Previous studies have investigated that the expression levels of MALAT-1 were higher in cancerous tissues than matched histologically normal tissues. And, to some extent, overexpression of MALAT-1 was inclined to lymph node metastasis. This meta-analysis collected all relevant articles and explored the association between MALAT-1 expression levels and lymph(More)
SNPs may restrict cell detoxification activity and be a potential risk factor for cancer chemosensitivity. We evaluated the predictive value of these polymorphisms on the sensitivity of bladder cancer patients to epirubicin and mitomycin chemotherapy instillation as well as their toxicities. SNPs were analyzed by TaqMan genotyping assays in 130 patients(More)
The association between DNA repair gene polymorphisms and bladder cancer risk has been widely studied. However, only few studies have examined the correlation between bladder cancer and instillation agent sensitivity. The aim of this study was to examine the association between polymorphisms of DNA repair genes, namely X-ray repair cross-complementing group(More)
OBJECTIVE The aim of this study was to develop a follow-up strategy based on the new model to reduce unnecessary prostate biopsies in patients with prostate specific antigen (PSA) ranging from 4 to 10 ng/ml. METHODS A total of 436 patients with PSA ranging from 4 to 10 ng/ml who had undergone transrectal ultrasound (TRUS)-guided prostate biopsy were(More)
The aim of the present study was to evaluate the value of systematic 12-and 13-core biopsies, guided by transrectal ultrasound (TRUS) or magnetic resonance imaging (MRI), with regard to the prostate cancer detection rate (PCDR).). Prostate biopsies were performed via systematic 12-or 13-core biopsy and guided by either TRUS or MRI. The PCDR was established(More)
