Previous studies have suggested a link between renal metabolism and local kidney hemodynamics to prevent potential hypoxic injury of particularly vulnerable nephron segments, such as the outer medullary region. The present study used three different inspiratory oxygen concentrations to modify renal metabolic state in the conscious rat (hypoxia 10% O2, normoxia 20% 02, and hyperoxia 100% 02). Re...

The aim of the study was to investigate mechanisms underlying the downregulation of renal blood flow (RBF) after a prolonged reduction in renal perfusion pressure (RPP) in adult spontaneously hypertensive rats (SHR). We tested the effect on the RBF response of clamping plasma ANG II in sevoflurane-anesthetized SHR. We also tested the effect of general cyclooxygenase (COX) inhibition and inhibit...

The industrial wastes fly ash (FA) and polypropylene (PP) were used to develop novel green composites using a renewable, cheap coupling agent i.e. stearic acid. The fly ash (FA) particles were coated with stearic acid (SA) in different weight % like 0, 1, 2, 3 and 5. The SA coated fly ash particles were incorporated as filler in recycled polypropylene (RPP) matrix which was obtained from post-c...

OBJECTIVE To correlate values of rate-pressure product (RPP) above 30,000 mmHg.bpm with or without significant obstructive coronary artery disease (CAD) in patients with positive exercise test. METHODS A retrospective analysis of 246 patients that had been submitted to Exercise Treadmill Test (ETT) up to 30 days before coronary angiography on suspicion of obstructive disease. The 165 patients...

The purpose of this study was to assess the Record Power Profile (RPP) of cyclists, i. e., the relationship between different record Power Output (PO) and the corresponding durations through a whole race season. We hypothesized that PO of different effort durations could differ according to the cyclist's category and race performance profile. 17 cyclists (9 professionals and 8 elites) performed...

BACKGROUND 1,3-dimethylamylamine (a constituent of geranium), alone and in combination with caffeine, is widely used within dietary supplements. We have recently determined the hemodynamic effects of 1,3-dimethylamylamine and caffeine alone and in combination, using a single ingestion study. However, no study has determined the hemodynamic effects of these ingredients following chronic use. Mor...

The interaction between Arabidopsis and the biotrophic oomycete Peronospora parasitica (downy mildew) provides an attractive model pathosystem to identify molecular components of the host that are required for genotype-specific recognition of the parasite. These components are the so-called RPP genes (for resistance to P. parasitica). Mutational analysis of the ecotype Wassilewskija (Ws-0) reve...

This paper proposes an application of evolutionary programming (EP) to reactive power planning (RPP) considering the highest load buses, instead of considering the randomly selected load buses to install the reactive power sources. The proposed approach has been used in the IEEE 30-bus system. Simulation results, compared with those obtained by using the previous method of RPP using EP, conside...

Cerebral blood flow dysregulation is often associated with hypertension. We hypothesized that a beetroot juice (BRJ) treatment could decrease blood pressure and cerebrovascular resistance (CVR). We subjected 12 healthy females to control and BRJ treatments. Cerebrovascular resistance index (CVRI), systolic blood pressure (SBP), total vascular resistance (TVR), and the heart rate-systolic pressu...
