Renal blood flow and oxygenation. [PDF]
Pflugers 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]
Bioelectronic MedicineBackground 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]
PeerJ, 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 ...

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

Journal 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]
Research 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

Effects of Platelet-Rich Plasma (PRP) on a Model of Renal Ischemia-Reperfusion in Rats. [PDF]
PLoS ONE, 2016 Renal ischemia-reperfusion injury is a major cause of acute renal failure, causing renal cell death, a permanent decrease of renal blood flow, organ dysfunction and chronic kidney disease.

eLife, 2022 Acute kidney injury is common, with ~13 million cases and 1.7 million deaths/year worldwide. A major cause is renal ischaemia, typically following cardiac surgery, renal transplant or severe haemorrhage.

THE ROLE OF L-TYPE CALCIUM CHANNELS IN THE MEDIATION OF FAST OSCILLATION OF ARTERIAL BLOOD PRESSURE AND RENAL BLOOD FLOW IN RATS [PDF]
Trakia Journal of Sciences, 2019 The investigation of dynamic characteristics of blood pressure and renal blood flow provides detailed information about the fast regulatory mechanisms involved in arterial blood pressure (ABP) and renal blood flow (RBF) autoregulation.
