PURPOSE We determined the cancer control provided by nephron sparing surgery for renal cell carcinoma greater than 4 cm. MATERIALS AND METHODS We performed a retrospective review of data on patients treated between 1980 and 2005. The case characteristics analyzed were patient age, surgical procedure, intraoperative parameters, complications, tumor size,(More)
The development of the ovarian follicle, oocyte maturation, and ovulation require a complex set of endocrine, paracrine, and autocrine inputs that are translated into the regulation of cyclic nucleotide levels. Changes in intracellular cAMP mediate the gonadotropin regulation of granulosa and theca cell functions. Likewise, a decrease in cAMP concentration(More)
To determine the cancer control afforded by radical prostatectomy in patients who underwent either an open, laparoscopic, or robotic procedure for localized prostate cancer. We collected data on all patients treated between 2000 and 2004. We recorded age, BMI, PSA, Gleason score and 2002 TNM stage, type of surgery, perioperative parameters, postoperative(More)
The ability of a bovine embryo to develop to the blastocyst stage, to implant and to generate a healthy offspring is not a simple process. To clarify the importance of the contribution of the oocyte to the embryo quality, it is important to define more precisely the different types of competence expressed by oocytes. The ability to resume meiosis, to cleave(More)
Gap-junctional communication (GJC) plays a central role in oocyte growth. However, little is known about the regulation of connexin 43 (Cx43)-based gap-junction channels in cumulus-oocyte complexes (COCs) during in vitro maturation. We show that rupture of COCs from mural granulosa cells up-regulates Cx43-mediated GJC and that gonadotropins signal GJC(More)
PURPOSE To evaluate the clinical and biologic safety of ultrasmall superparamagnetic iron oxide particles (AMI-227) as a contrast agent for magnetic resonance (MR) lymphography and to assess their efficacy for the differentiation of metastatic and benign nodes in patients with urologic and pelvic cancer. MATERIALS AND METHODS Thirty adults suspected of(More)
OBJECTIVES To compare the outcomes in patients who had undergone either open nephroureterectomy or conservative endoscopic surgery (ureteroscopic or percutaneous management) for upper urinary tract transitional cell carcinoma. METHODS We performed a retrospective review of the data for patients treated surgically for upper urinary tract transitional cell(More)
It is generally accepted that cyclic nucleotides are key signaling molecules in the control of oocyte meiotic resumption. Given the role of phosphodiesterases (PDEs) in cyclic nucleotide degradation, this study was undertaken to investigate the properties and regulation of PDEs expressed in rat oocytes. Cilostamide-sensitive PDE3 was the major activity(More)
In eukaryotic cells, the inactivation of the cyclic nucleotide signal depends on a complex array of cyclic nucleotide phosphodiesterases (PDEs). Although it has been established that multiple PDE isoenzymes with distinct catalytic properties and regulations coexist in the same cell, the physiological significance of this remarkable complexity is poorly(More)
The International Prostate Symptom Score, which was proposed during the First Consultation on Benign Prostatic Hyperplasia in June 1991, was culturally adapted and linguistically validated in French. In a first step, the English version, adapted from the questionnaire developed by the American Urological Association, was translated into French. In a second(More)
