OBJECTIVE Electroencephalography (EEG) is a challenge to record simultaneously with functional MRI (fMRI), for it is prone to large artifacts induced by both the static and the time-variant fields of the MR scanner. However, truly concurrent EEG/fMRI recording has great potential for clinical and scientific neurological applications. We have devised a(More)
PURPOSE We examined the effect of radical nephrectomy, partial nephrectomy and radio frequency ablation on renal function in patients with stage T1a renal masses. MATERIALS AND METHODS A total of 242 consecutive patients from July 1995 to March 2005 undergoing primary treatment for unilateral renal masses smaller than 4 cm and a normal contralateral(More)
BACKGROUND Unilateral ureteral obstruction (UUO) is characterized by progressive renal atrophy, renal interstitial fibrosis, an increase in renal transforming growth factor-beta (TGF-beta), and renal tubular apoptosis. The present study was undertaken to determine the effect of a monoclonal antibody to TGF-beta (1D11) in UUO. METHODS Mechanical stretch(More)
PURPOSE Positive surgical margins are an independent predictive factor for biochemical recurrence after radical prostatectomy. We analyzed the incidence of and associative factors for positive surgical margins in a multi-institutional series of 8,418 robotic assisted radical prostatectomies. MATERIALS AND METHODS We analyzed the records of 8,418 patients(More)
A probability may be col l ed " default " if it is neither derived from preestablished probabilities nor bosed on considerations of frequency or symmetry. Default probabilities presumably arise through reasoning based on causality ond similarity. This article advances o model of default probobility based on o feoturol approach to similarity. The accuracy of(More)
OBJECTIVE To compare the intermediate-term outcomes of patients with clinical T1a renal tumours who were treated with nephron-sparing surgery by partial nephrectomy (PN), the preferred approach for small (cT1a) renal tumours, or radiofrequency ablation (RFA), recently offered to selected patients as an alternative, less morbid technique. PATIENTS AND(More)
Progression of renal damage after relief of unilateral ureteral obstruction (UUO) has been demonstrated, especially in neonatal rats. We evaluated renal function and renal damage after relief of 3-day UUO in five groups of adult rats: group 1, no treatment; group 2, 3-day UUO; groups 3-5, 3-day UUO followed by relief; group 3, 7-day relief; group 4, 14-day(More)
OBJECTIVES Patients can search the Internet for prostate cancer information, and YouTube is a popular Web site that they may consult. We analyzed the prostate cancer videos on YouTube for information content and the presence of bias. METHODS YouTube was searched for videos about prostate-specific antigen (PSA) testing, radiotherapy, and surgery for(More)
BACKGROUND AND PURPOSE Postoperative incontinence is multifactorial after radical prostatectomy. Using endorectal coil MRI, we examined features of the male urethra and accompanying muscular sphincter to predict continence after robot-assisted radical prostatectomy (RARP). PATIENTS AND METHODS 80 patients underwent preoperative 1.5 Tesla endorectal coil(More)
PURPOSE Laser activated gold nanoshell thermal ablation represents a new, minimally invasive technology that offers benign tissue sparing thermal ablation of malignant tumors. We evaluated the efficacy of this technology for eradicating prostate cancer in a subcutaneous tumor model. MATERIALS AND METHODS The 110 nm gold nanoshells with a 10 nm gold shell(More)
