Cordycepin, (3'-deoxyadenosine), a bioactive compound of Cordyceps militaris, has been shown to exhibit many pharmacological actions, such as anti-inflammatory, antioxidative and anticancer activities. Little is known about the neuroprotective action of cordycepin as well as its molecular mechanisms. In this study, cordycepin was investigated for its(More)
We study the problem of traffic grooming in wavelength-division-multiplexing (WDM) rings with dynamic traffic. We consider both unidirectional and bi-directional rings. In our dynamic traffic model, traffic is represented by a set of different traffic requirements that the network needs to satisfy, but at different times. Our objective is to minimize the(More)
BACKGROUND AND PURPOSE Bipolar energy has recently been used as a common alternative to conventional monopolar transurethral resection of the bladder (TURB) while managing nonmuscle-invasive bladder cancer (NMIBC). We established a meta-analysis comparing the safety and efficacy of plasmakinetic bipolar and monopolar TURB for NMIBC. METHODS A systematic(More)
For the treatment of large upper urinary stones percutaneous nephrolithotomy (PCNL) is generally considered the first choice, and Laparoscopic Stone Surgery (LSS) is an alternative. We aim to compare the efficiency and safety of PCNL with LSS, as far as the management of large upper urinary stones is concerned. A systematic search from Pubmed, Web of(More)
OBJECTIVES To compare the safety and efficacy of thulium laser resection of prostate (ThuRP) and plasmakinetic resection of prostate (PKRP) for benign prostate hyperplasia (BPH), we made this meta-analysis in regard of the two techniques. METHODS A systematic search of PubMed, Web of Science, and China National Knowledge Infrastructure was performed up to(More)
In this talk, we present a web-based virtual factory that operates in “real time” and will be managed by teams of engineering students in the context of a course on Discrete Event Dynamic Systems. This project aims at an integrative and innovative approach to curriculum development that departs significantly from the current methods of teaching engineering(More)
PURPOSE tRNA fragments are dysregulated in various malignancies. Our study was designed to determine the expression of four 5'-tRNA-halves in tissue and serum of clear cell renal cell carcinoma (ccRCC) patients. MATERIALS AND METHODS Tissue and serum samples of patients with ccRCC and non-malignant disease were collected prospectively in our Biobank. We(More)
INTRODUCTION To evaluate the efficiency and safety of the paravertebral block (PVB) as the single main anesthesia for unilateral mini-invasive percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS Forty-five American Society of Anesthesiologists grade I/II/III patients with large upper urinary tract stones were included in our retrospective study.(More)
BACKGROUND The treatment of bilateral complex renal stones is a tough challenge for urologists. This study aimed to evaluate the efficiency and safety of bilateral ultrasonography-guided multi-tract percutaneous nephrolithotomy (PCNL) combined with EMS lithotripsy for the treatment of such cases. METHODS Twenty-seven patients suffering from bilateral(More)
