The aim of this study was to investigate a single-institution experience with radical perineal prostatectomy (RPP), radical retropubic prostatectomy (RRP) and minimally invasive radical prostatectomy (MIRP) with respect to onco-surgical outcomes in patients with intermediate-risk (IR; PSA 10-20 ng/mL, biopsy Gleason score bGS 7 or cT2b-2c) and high-risk (HR; PSA > 20 ng/mL, bGS ≥ 8, or ≥ cT3) p...

In this paper, we describe our design for a new electrohydraulic (EH) pump-driven renal perfusion pressure (RPP)-regulatory system capable of implementing precise and rapid RPP regulation in experimental animals. Without this automated system, RPP is manually controlled via a blood pressure clamp, and the imprecision in this method leads to compromised RPP data. This motivated us to develop an ...

The susceptibility to renal perfusion pressure (RPP)-induced renal injury was investigated in angiotensin II (Ang II)- versus norepinephrine (NE)-infused hypertensive rats. To determine the magnitude of RPP-induced injury, Sprague-Dawley rats fed a 4% salt diet were instrumented with a servocontrolled aortic balloon occluder positioned between the renal arteries to maintain RPP to the left kidn...

Rate Pressure Product (RPP) is a valuable marker of cardiac function.It is the product of heart rate (HR) and systolic blood pressure (SBP) (HR x SBP/1000). RPP up to 12 at rest and up to 22 in stressed conditions is considered as normal. This study deals with RPP evaluation in60 young normal subjects of 18 to 22 years old (30 males and 30 females).HR and SBP were recorded before and after 5 mi...

Recent studies have shown that rambutan peel phenolic (RPP) extract demonstrate high antioxidant and antiglycation activities in vitro and in vivo. This study further evaluated the anti-diabetic activity of RPP in a mouse model of Type II diabetes induced by streptozotocin combined with high-fat diet. Results showed that RPP increased the body weight and reduced the fasting blood glucose level ...

Independent Antihypertensive Effect? To the Editor: In a recent issue of Circulation, Nafz and colleagues1 described the antihypertensive effects of oscillations of renal perfusion pressure (RPP) in conscious dogs. One of the key findings in that article was that plasma renin activity increased in response to a decrease in the mean RPP to 85 mm Hg; this increase was significantly reduced by 0.1...

The present study was designed to take advantage of telemetry data acquisition and develop an easy and reliable system to servocontrol renal perfusion pressure (RPP). Digitized pressure signals from lower abdominal aorta in rats, reflecting RPP, was obtained by a telemetry device and dynamically exported into an Excel worksheet. A computer program (LabVIEW) compared the RPP data with a preselec...

Pressure-dependent urine production is considered to be a major factor in long-term blood pressure control. The phenomenon has been well characterized for fixed levels of renal perfusion pressure (RPP), but the influence of physiological fluctuations in RPP and spontaneous variations in renal blood flow (RBF) on short-term urine flow (UV) remain unclear. To clarify this issue, we studied the in...

In this paper the rectangle packing problem (RPP) is considered. The RPP consists in finding a packing pattern of small rectangles within a larger rectangle such that the area utilization is maximized, We develop new heuristics for the RPP which are based on the G4-heuristic for the pallet loading problem. In addition to the general RPP we take also into account further restrictions which are o...
