Renal blood flow and oxygenation. [PDF]

open access: yesPflugers Arch, 2022
Our 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.

Renal pericytes: regulators of medullary blood flow [PDF]

open access: yesActa Physiologica, 2012
Regulation of medullary blood flow (MBF) is essential in maintaining normal kidney function. Blood flow to the medulla is supplied by the descending vasa recta (DVR), which arise from the efferent arterioles of juxtamedullary glomeruli.

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 ...

Pericyte-mediated constriction of renal capillaries evokes no-reflow and kidney injury following ischaemia [PDF]

open access: yeseLife, 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.

Renal blood flow in sepsis [PDF]

open access: yesCritical Care, 2005
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 libraries to identify ...

Electrically stimulated acupuncture increases renal blood flow through exosome-carried miR-181.

open access: yesAm J Physiol Renal Physiol, 2018
Acupuncture with low-frequency electrical stimulation (Acu/LFES) can prevent muscle atrophy by increasing muscle protein anabolism in mouse models of chronic kidney disease.

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.

Glomerular Filtration Rate, Renal Blood Flow and Blood Viscosity during and after Diabetic Coma [PDF]

open access: bronzeCirculation Research, 1953
The azotemia of patients in diabetic coma is the result of impaired blood supply, unless tubular impairment antedates or supervenes. Clearance and blood pressure data are presented which strongly suggest that increased blood viscosity is the dominant ...
