The chronic role of nitric oxide (NO), independent of prostaglandin synthesis, in the primary peripheral vasodilation, increased glomerular filtration rate (GFR), and renal plasma flow (RPF) in normal pregnancy remains to be defined. The purpose of the present study was to chronically inhibit NOS to return systemic vascular resistance (SVR), cardiac output (CO), GFR, and RPF to nonpregnant valu...

OBJECTIVE To clarify the characteristics of renal haemodynamics in patients with lupus nephritis (LN). METHODS The glomerular filtration rate (GFR) and renal plasma flow (RPF) of 37 patients with active LN were studied longitudinally over an interval of 8 to 144 weeks during treatment with corticosteroids or cytotoxic drugs, or both. All patients had clinical renal disorders and underwent ren...

Mycobacterium tuberculosis and its close relative, Mycobacterium bovis (BCG) contain five genes whose predicted products resemble Rpf from Micrococcus luteus. Rpf is a secreted growth factor, active at picomolar concentrations, which is required for the growth of vegetative cells in minimal media at very low inoculum densities, as well as the resuscitation of dormant cells. We show here that th...

A three-compartment model is proposed for analyzing magnetic resonance renography (MRR) and computed tomography renography (CTR) data to derive clinically useful parameters such as glomerular filtration rate (GFR) and renal plasma flow (RPF). The model fits the convolution of the measured input and the predefined impulse retention functions to the measured tissue curves. A MRR study of 10 patie...

In this paper we have proposed a practical approach for broadcasting in wide area networks. The concept of pseudodiameter, an important parameter in the DVR data structure unused by the RPF method has been applied to prune the flow of packets in order to achieve reduction in the number of the duplicate packets generated during broadcasting. Performance comparison with the classical RPF method s...

With the dramatic increased use of agricultural film, potential environmental risks associated with it have been receiving widespread attention. Biodegradable film (BF) is considered an alternative to conventional polyethylene (PF), but its feasibility replace PF needs be verified. Thus, we conducted a two-year field experiment in Loess Plateau region China, exploring effects residual biodegrad...

BACKGROUND L-Arginine, the substrate of nitric oxide (NO) synthase, and N(G)-monomethyl-L-arginine (L-NMMA), a competitive inhibitor of endothelial NO synthase, are used to analyze endothelial function of the renal vasculature. However, little is known about the appropriate dose of L-arginine to be used and the duration of action of L-arginine and L-NMMA. METHODS Twenty-nine healthy male subj...

A Protocol Independent Multicast (PIM) router uses the Reverse Path Forwarding (RPF) procedure to select an upstream interface and router in order to build forwarding state. When there are equal-cost multipaths (ECMPs), existing implementations often use hash algorithms to select a path. Such algorithms do not allow the spread of traffic among the ECMPs according to administrative metrics. This...

Abstract Toxic stress (TS), resiliency-promoting factors (RPFs) and their interactions were investigated in relationship to incident dementia a sample (n = 6516) of US adults ≥50 years old enrolled the HRS between 2006-2016. TS included experiences everyday discrimination RPF personal mastery. Race/ethnicity was self-reported as African American (AA), Caucasian, or Other. Multivariable Cox prop...

Two patients who had acute pancreatitis subsequently developed characteristic appearance on urography of smooth extrinsic narrowing and medial deviation of the right ureter suggestive of retroperitoneal fibrosis (RPF) resulting in ureteric obstruction. Both these patients had clinical, biochemical and sonographic evidence of acute pancreatitis. CT scan of the abdomen performed on the second pat...
