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 ...

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 ...

The renal blood flow reserve in healthy humans and patients with atherosclerotic renovascular disease measured by positron emission tomography using [15O]H2O [PDF]

open access: yesEJNMMI Research, 2018
Background Microvascular function plays an important role in ARVD (atherosclerotic renovascular disease). RFR (renal flow reserve), the capacity of renal vasculature to dilate, is known to reflect renal microvascular function.

Comparison of Renal Blood Flow Using Maximum Slope-Based Computed Tomography Perfusion and Ultrasound Flow Probe in Healthy Dogs [PDF]

open access: yesFrontiers in Veterinary Science, 2020
Computed tomography (CT) perfusion can analyze tissue perfusion and quantitative parameters, including blood flow, blood volume, and transit time. CT perfusion has been used for evaluating split renal function.

Molecular mechanisms of renal blood flow autoregulation. [PDF]

open access: yesCurr Vasc Pharmacol, 2014
Diabetes and hypertension are the leading causes of chronic kidney disease and their incidence is increasing at an alarming rate. Both are associated with impairments in the autoregulation of renal blood flow (RBF) and greater transmission of fluctuations in arterial pressure to the glomerular capillaries.

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 ...
