Renal blood flow and oxygenation. [PDF]

open access: yesPflugers Arch, 2022
AbstractOur kidneys receive about one-fifth of the cardiac output at rest and have a low oxygen extraction ratio, but may sustain, under some conditions, hypoxic injuries that might lead to chronic kidney disease. This is due to large regional variations in renal blood flow and oxygenation, which are the prerequisite for some and the consequence of ...

Renal nerve stimulation modulates renal blood flow in a frequency-dependent manner [PDF]

open access: yesBioelectronic Medicine
Background Chronic overactivity of the renal nerves is a key pathophysiological attribute of drug-resistant hypertension. Indeed, catheter-based renal denervation can lower blood pressure by severing the brain-kidney (efferent nerves) and kidney-brain ...

TRPV1 protects renal ischemia-reperfusion injury in diet-induced obese mice by enhancing CGRP release and increasing renal blood flow [PDF]

open access: yesPeerJ, 2019
Background Obesity is a major risk factor for end-stage renal disease. Using transient receptor potential vanilloid 1 knockout (TRPV1−/−) mice, we tested the hypothesis that TRPV1 protects against obesity-induced exacerbation of renal ischemia ...

Evaluation of Renal Blood Flow in Chronic Kidney Disease Using Arterial Spin Labeling Perfusion Magnetic Resonance Imaging

open access: yesKidney International Reports, 2017
Chronic kidney disease (CKD) is known to be associated with reduced renal blood flow. However, data in humans are limited to date. Methods: In this study, noninvasive arterial spin labeling magnetic resonance imaging data were acquired in 33 patients ...

Blood Flow in the Renal Medulla [PDF]

open access: yesCirculation Research, 1961
The accumulation of intra-arterially injected I 131 albumin in the papilla of the kidney was measured in a series of 33 anesthetized dogs producing hypertonic urine. Although the data were widely scattered, an estimate of the average rate of this accumulation during the first half-minute following the start of the ...

Renal blood flow in sepsis [PDF]

open access: yesCritical Care, 2005
Abstract Introduction To assess changes in renal blood flow (RBF) in human and experimental sepsis, and to identify determinants of RBF. Method Using specific search terms we systematically interrogated two electronic reference ...

Simulation and Analyses of Turbulent Flow in Different Phases of Stenosed Renal Artery [PDF]

open access: yesMATEC Web of Conferences, 2023
This study concerns the two-dimensional structure computational results of renal artery stenosis. In this paper, the turbulent flow of the stenosed vessel is stimulated and correlates the different stages of stenosis with each other.

Salt‐Sensitive Hypertension, Renal Injury, and Renal Vasodysfunction Associated With Dahl Salt‐Sensitive Rats Are Abolished in Consomic SS.BN1 Rats

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Abnormal renal hemodynamic responses to salt‐loading are thought to contribute to salt‐sensitive (SS) hypertension. However, this is based largely on studies in anesthetized animals, and little data are available in conscious SS and salt ...

PHARMACOLOGICAL CORRECTION OF INTERCEPT HEMODYNAMICS IN ACUTE KIDNEY DAMAGE (PART 1) [PDF]

open access: yesResearch Results in Pharmacology, 2017
Introduction: Development of vasoconstriction of kidney arterioles and reduction of renal blood flow is one of the main mechanism of acute kidney injury (AKI) formation. Methods for evaluation of intrarenal hemodynamics status are rather limited. Evident
