Simulation can be an important step in the development of software for wireless sensor networks and has been the subject of intense research in the past decade. While most previous efforts in simulating wireless sensor networks have focused on protocol-level issues utilizing models of the software implementation, a significant challenge remains in precisely(More)
BACKGROUND Sciatic perineural catheters via a popliteal fossa approach and subsequent local anesthetic infusion provide potent analgesia and other benefits after foot and ankle surgery. Electrical stimulation (ES) and, more recently, ultrasound (US)-guided placement techniques have been described. However, because these techniques have not been compared in(More)
OBJECTIVE To determine whether the interval between prostate biopsy and radical prostatectomy (RP) affects the immediate postoperative outcome. PATIENTS AND METHODS The study was a retrospective chart review of 169 patients who had retropubic RP at our institution. Using a series of univariate and multivariate logistic regression analyses, we evaluated(More)
Antimicrobials are routinely used in the treatment of chronic and problematic wounds. Despite the on-going increase in numbers and types of products, well-designed clinical trials that support their efficacy are limited. Antimicrobial products are applied with understanding of their mechanisms of action and role in wound repair. This manuscript reviews the(More)
The purpose of this study was to clarify the association between CT findings and Fuhrman grade of clear cell renal cell carcinoma (ccRCC). The study group consisted of 214 surgically proven ccRCC in 214 patients. Contrast-enhanced CT studies were retrospectively assessed for tumor size, cystic versus solid, calcification, heterogeneity of lesions,(More)
BACKGROUND Proliferative inflammatory atrophy (PIA) of the prostate is a common histological finding that has been postulated to be associated with prostate cancer. We examine PIA lesions for the expression of p16/CDKN2, a cyclin-dependent kinase inhibitor frequently altered in prostate cancer. METHODS Within tissues from two independent patient(More)
BACKGROUND Pneumoperitoneum after cardiopulmonary resuscitation may be due to mediastinal air tracking into the peritoneal cavity via the diaphragmatic hiatus or to gastric perforation. CASE REPORT A 79-year-old woman received Advanced Cardiac Life Support measures in the intensive care unit. Chest compressions and endotracheal intubation were performed;(More)
A kinetic model of the effect of agonist and anesthetics on ligand-gated ion channels, developed in earlier work, is further refined and used to predict traces observed in fast-perfusion electrophysiological studies on recombinant GABAA receptors under a wide range of agonist and/or anesthetic concentrations. The model incorporates only three conformational(More)
