This paper presents an index-based checkpointing algorithm for distributed systems with the aim of reducing the total number of checkpoints while ensuring that each checkpoint belongs to at least one consistent global checkpoint (or recovery line). The algorithm is based on an equivalence relation deened between pairs of successive c heckpoints of a process(More)
BACKGROUND Laparoendoscopic single-site surgery (LESS) has gained popularity in urology over the last few years. OBJECTIVE To report a large multi-institutional worldwide series of LESS in urology. DESIGN, SETTING, AND PARTICIPANTS Consecutive cases of LESS done between August 2007 and November 2010 at 18 participating institutions were included in this(More)
We conducted a prospectively randomised clinical trial to investigate the role of adjuvant outpatient immunochemotherapy administered postoperatively in high-risk patients with renal cell carcinoma. In total, 203 renal carcinoma patients' status post radical tumour nephrectomy were stratified into three risk groups: patients with tumour extending into renal(More)
Background. Because obesity may be a risk factor for prostate cancer, we investigated proliferative effects of adipocytes-derived hormone leptin on human prostate cancer cells and assessed the role of mitogen-activated protein kinase (MAPK) signaling pathway in mediating these actions. Material and Methods. Three human prostate cancer cell lines were(More)
Microinjection is established as the method of choice in the treatment of severe male factor infertility as well as in azoospermic patients. Recent studies have shown that fertilization and cleavage can be achieved by injection of ejaculated as well as testicular elongated spermatids into oocytes. Here we report on the two first pregnancies worldwide(More)
We performed a prospectively randomised clinical trial to compare the efficacy of four subcutaneous interleukin-2-(sc-IL-2) and sc interferon-a2a (sc-IFN-a2a)-based outpatient regimens in 379 patients with progressive metastatic renal cell carcinoma. Patients with lung metastases, an erythrocyte sedimentation rate p70 mm h À1 and neutrophil counts p6000 ml(More)
BACKGROUND Laparoscopy is believed to result in possible clinical benefits for the patient. We report our experience with renal laparoscopy in dialysis patients and compare the results with those from non-dialysis patients. METHODS Between December 1994 and April 1997, 19 dialysis patients underwent laparoscopic nephrectomy or nephroureterectomy at our(More)
Members of the urokinase-type plasminogen activator (uPA) system including uPA, its receptor uPAR and the plasminogen activator inhibitor 1 (PAI-1) play an important role in tumour invasion and progression in a variety of tumour types. Since the majority of clear cell renal cell carcinoma (ccRCC) shows distant metastasis at time of diagnosis or later, the(More)
BACKGROUND AND METHODS Circulating tumor cells (CTCs) constitute a useful approach for personalized medicine. Nevertheless, the isolation of these cells remains very challenging because they rarely circulate in the blood. Another current problem is the cancer-specific characterization of these cells, which requires a method that allows for the molecular and(More)
