OBJECTIVES To determine the oncologic safety of laparoscopic nephroureterectomy (LNU), we compared the long-term oncologic outcome of LNU versus open nephroureterectomy (ONU) in patients with upper tract transitional cell carcinoma. METHODS A total of 367 nephroureterectomy procedures were performed at our institutes for upper tract transitional cell(More)
Expression of virulence-related extracellular proteases, gelatinase, and serine protease of Enterococcus faecalis is regulated by a quorum-sensing system encoded by the fsr gene cluster. In this study, a 23.9-kb chromosomal deletion containing the fsr gene cluster region was found to be present in the majority (79%) of gelatinase-negative clinical isolates(More)
Staphylococci have been confirmed to form biofilms on various biomaterials. The purpose of this study was to investigate biofilm formation among methicillin-resistant Staphylococcus aureus (MRSA) isolates from patients with urinary tract infection (UTI) and to assess the relationship between biofilm-forming capacities and virulence determinants/clinical(More)
The reduced expression in immortalized cells (REIC)/Dickkopf (Dkk)-3, a member of the Dkk gene family, is a tumor suppressor in a broad range of cancers. REIC/Dkk-3 transfected stable clones of mouse prostate cancer RM9 cells (RM9-REIC) and the empty vector-transfected control clone cells (RM9-EV) were established. Clones were used to evaluate the(More)
Conditions have been optimized for the use of a multiplex PCR for the detection of vancomycin-resistant enterococci in nosocomial surveillance specimens. Seven primer sets targeting the genes vanA, vanB, vanC1, vanC2/C3 Enterococcus faecalis-specific, Enterococcus faecium-specific, and rrs (16S rRNA) were used in one reaction tube. The PCR method developed(More)
Alteration in genes which takes place during malignant conversion and progression could be potential targets for gene therapy. We previously identified REIC/Dkk-3 as a gene whose expression is reduced in many human cancers. Here, we showed that expression of REIC/Dkk-3 was consistently reduced in human prostate cancer tissues in a stage-dependent manner.(More)

Bacterial biofilms develop on a number of living and inert surfaces within the urinary tract, producing chronic intractable infections. The role of exopolysaccharides in producing a variety of extracellular polymeric substances according to the infection site and bacterial species and the clinical features of the resulting biofilm infections were reviewed.(More)
AIM The standard management of varicocele repair is the subject of ongoing controversy. We retrospectively evaluated three surgical methods of varicocele treatment to determine the minimally invasive and most effective procedure. METHODS We performed 144 varicocelectomies on infertile patients with left clinical varicocele. Of the patients, 50 were(More)
The overexpression of reduced expression in immortalized cells (REIC)/Dickkopf-3 (Dkk-3), a tumor suppressor gene, induced apoptosis in human prostatic and testicular cancer cells. The aim of this study is to examine the potential of REIC/Dkk-3 as a therapeutic target against breast cancer. First, the in vitro apoptotic effect of Ad-REIC treatment was(More)
As a human prostate cancer gene therapy trial, we have performed Herpes Simplex Virus-thymidine kinase gene transduction and ganciclovir therapy in locally advanced prostate cancer after radiation therapy(USA) or endocrine therapy(Japan). Safety and clinical efficacy were confirmed. In our current studies, we demonstrated the efficacy and safety of gene(More)
