OBJECTIVE We investigated whether diabetes mellitus is associated with the cancer-related outcomes in patients with localized clear cell renal cell carcinoma treated with radical or partial nephrectomy. METHODS We reviewed data from 950 patients who received radical or partial nephrectomy for localized clear cell renal cell carcinoma from 1988 to 2009. We(More)
UNLABELLED There has been some controversy about the gender differences in survival in patients with RCC. Korean women with RCC had a lower proportion of clear cell histology and a higher proportion of chromophobe histology. This histological difference might have driven the better survival rates in Korean women. OBJECTIVE To assess whether there are(More)
To investigate whether diabetes mellitus (DM) was associated with postoperative outcomes, including prostate-specific antigen doubling time, among men who underwent radical prostatectomy (RP) for clinically localized prostate cancer (PCa). Data of 661 patients who underwent radical prostatectomy for node-negative prostate cancer and were followed up for ≥3(More)
This work demonstrates a large-scale batch fabrication of GaN light-emitting diodes (LEDs) with patterned multi-layer graphene (MLG) as transparent conducting electrodes. MLG films were synthesized using a chemical vapor deposition (CVD) technique on nickel films and showed typical CVD-synthesized MLG film properties, possessing a sheet resistance of(More)
Graphene is a promising next-generation conducting material with the potential to replace traditional electrode materials such as indium tin oxide in electrical and optical devices. It combines several advantageous characteristics including low sheet resistance, high optical transparency and excellent mechanical properties. Recent research has coincided(More)
PURPOSE The purpose of this article was to announce the establishment of the multicenter Korean Prostate Cancer Database (K-CaP) and to provide urologists with details about K-CaP's methodology. MATERIALS AND METHODS The initial participating K-CaP institutions include five medical centers in Korea. First, we registered prostate cancer patients who(More)
PURPOSE To evaluate whether the risk of prostate cancer was different according to the pattern of fluctuation in prostate-specific antigen (PSA) levels in patients undergoing repeat transrectal ultrasound-guided prostate biopsy (TRUS-Bx). METHODS From March 2003 to December 2012, 492 patients underwent repeat TRUS-Bx. The patients were stratified into 3(More)
A new touch sensor device has been demonstrated with molybdenum disulfide (MoS2) field effect transistors stacked with a piezoelectric polymer, polyvinylidene fluoride-trifluoroethylene (PVDF-TrFE). The performance of two device stack structures, metal/PVDF-TrFE/MoS2 (MPM) and metal/PVDF-TrFE/Al2O3/MoS2 (MPAM), were compared as a function of the thickness(More)
BACKGROUND AND PURPOSE Robot-assisted partial nephrectomy (RPN) has emerged as a viable alternative to open partial nephrectomy (OPN) for small renal masses (SRMs). Comparative outcomes of RPN and OPN at a single institution were analyzed. PATIENTS AND METHODS A retrospective review was performed to compare 69 RPNs with 234 OPNs between May 2003 and(More)
UNLABELLED What's known on the subject? and What does the study add? Previously, it has been reported that PSA may not perform as accurately as PSA density (PSAD) in predicting outcomes after radical prostatectomy among patients with Gleason score 6 prostate cancer. However, there have been few studies comparing the usefulness of PSA and PSAD in predicting(More)
