OBJECTIVE To clarify the impact of radical perineal prostatectomy (RPP) on lower urinary tract symptoms (LUTS) in patients with clinically localized prostate cancer. METHODS A total of 117 patients with a median age of 69 years who underwent RPP alone between August 2002 and August 2005 were included in the study. We measured LUTS on the basis of the International Prostate Symptom Score (IPSS...

The main purpose of this study was to examine the effect of Radix Pseudostellariae polysaccharides (RPPs) against swimming exercise-induced oxidative stress in male rats. A total of 40 male Wistar rats were randomized into four groups: the control (C), low-dose RPP supplementation (LRS), medium-dose RPP supplementation (MRS) and high-dose RPP supplementation (HRS) groups. The control group rece...

We used flow cytometry to analyze the expression of adhesion molecules and the oxidative burst of whole-blood polymorphonuclear neutrophils (PMN) from 26 patients with periodontitis. Three different clinical entities were studied: adult periodontitis (AP), localized juvenile periodontitis (LJP), and rapidly progressive periodontitis (RPP). Unstimulated PMN from the patients showed reduced Lewis...

Objective: We designed a novel technique of suctioning flexible ureteroscopy with automatic control of renal pelvic pressure (RPP) by a patented system including a pressure-measuring ureteral access sheath (UAS) and an irrigation and suctioning platform. We sought to compare RPP values measured by the patented system and a nephrostomy catheter at different phases of flexible ureteroscopy. Mater...

INTRODUCTION The aim of this study is to evaluate the anorectal functions of prostate cancer patients who have undergone radical perineal prostatectomy (RPP) or radical retropubic prostatectomy (RRP) surgery. MATERIAL AND METHODS Thirty-seven patients with an indication for radical prostatectomy were included after informed consent. Anorectal manometry was performed before and one month after...

BACKGROUND Physiological blood pressure (BP) fluctuations with frequencies >0.1 Hz can override renal blood flow autoregulation. The influence of such immediate changes in renal perfusion pressure (RPP) on daily BP regulation, eg, via shear stress-stimulated liberation of renal endothelial NO, however, is unknown. Thus, we studied the effects of such RPP oscillations on renal function and on sy...

It has been known that Reproducing Kernel Particle (RKP) shape functions with Kronecker delta property are not available in simple forms. Thus, in this paper, we construct highly regular piecewise polynomial Reproducing Polynomial Particle (RPP) shape functions that satisfy the Kronecker Delta Property. Like RKP shape functions, the RPP shape functions reproduce the complete polynomials of degr...

This paper analyzes the impact on mobile telephony diffusion patterns of the two predominant payment regimes, calling party pays (CPP) and receiving party pays (RPP), for mobile termination services. By applying instrumental variable techniques to panel data we account for a possible interdependency of penetration rates and regulatory interventions. For this purpose we use data on political and...

Abnormal renovascular reactivity, characterized by paradoxical vasoconstriction to a reduction in renal perfusion pressure (RPP) in the autoregulatory range, increased sensitivity to renal nerve stimulation (RNS), and loss of vasodilatation to acetylcholine have all been demonstrated in ischemic acute renal failure (ARF). To determine if ischemic injury alters vascular contractility by increasi...

An open question in the study of quasiconvex function is the characterization of the class of functions which are sum of quasiconvex functions. In this paper we restrict attention to quasiconvex radiant functions, i.e. those whose level sets are radiant as well as convex and deal with the claim that a function can be expressed as the sum of quasiconvex radiant functions if and only if it is rad...
