We hypothesized that renal denervation in mature ovine fetuses reduces renin mRNA response to 24 h of reduced renal perfusion pressure (RPP). Seven occluder (O) (132.4 +/- 1.2 days gestation) and six control (C) (131.5 +/- 1.2 days gestation) fetuses underwent left renal denervation. Postoperatively, O fetuses experienced 24 h of reduced RPP by suprarenal aortic occlusion. Femoral arterial bloo...

In this paper, we study electromagnetic wave scattering from periodic structures and eigenvalue analysis of the Helmholtz equation. Boundary element method (BEM) is an effective tool to deal with Helmholtz problems on bounded as well as unbounded domains. Recently, Oh et al.([29]) developed reproducing polynomial boundary particle methods (RPBPM) that can handle effectively boundary integral eq...

Non-science majors gain valuable insight studying clinical trials literature: an evidence-based medicine library assignment. Adv Physiol Educ 28: 188–194, 2004; doi:10.1152/advan.00029.2003.—When faced with a diagnosis, it is empowering to be able to assess the evidence of treatment effectiveness and safety. To ...

The objective of this study was to test the hypothesis that a decrease in renal interstitial hydrostatic pressure (RIHP) accounts for the blunted pressure natriuresis during pregnancy. RIHP was measured in nonpregnant (NP; n = 9), midterm pregnant (MP; 12-14 days after conception; n = 10), and late-term pregnant (LP; 18-21 days after conception; n = 12) female Sprague-Dawley rats at two renal p...

The importance of renal perfusion pressure (RPP), the sympathetic beta adrenergic nervous system and renal prostaglandins (PG) on renin release during a uniform 15-17% reduction in blood pressure by hemorrhage (HH) was studied systematically in anesthetized dogs. All groups of animals had similar decrements in systemic and renal hemodynamics with HH. In control dogs (n = 7), both plasma renin a...

Actinobacillus actinomycetemcomitans has been closely associated with early-onset, severe periodontitis, and such patients often have serum immunoglobulin G (IgG) antibodies reactive with antigens of this gram-negative pathogen. We examined the functionality and potential importance of these antibodies. The opsonic activity against A. actinomycetemcomitans of sera from 30 patients with rapidly ...

This study examined the effects of chronic blockade of the renal formation of epoxyeicosatrienoic acids and 20-hydroxyeicosatetraenoic acid with 1-aminobenzotriazole (ABT; 50 mg.kg(-1). day(-1) ip for 5 days) on pressure natriuresis and the inhibitory effects of elevations in renal perfusion pressure (RPP) on Na(+)-K(+)-ATPase activity and the distribution of the sodium/hydrogen exchanger (NHE)...

Previous experiments from our laboratory have shown that longer lasting reductions in renal perfusion pressure (RPP) are associated with a gradual decrease in renal blood flow (RBF) that can be abolished by clamping plasma angiotensin II concentration ([Ang II]). The aim of the present study was to investigate the mechanisms behind the RBF downregulation in halothaneanaesthetized Sprague Dawley...

The vast majority of published results in the literature is statistically significant, which raises concerns about their reliability. The Reproducibility Project Psychology (RPP) and Experimental Economics Replication Project (EE-RP) both replicated a large number of published studies in psychology and economics. The original study and replication were statistically significant in 36.1% in RPP ...
