Intrarenal oxygenation: unique challenges and the biophysical basis of homeostasis
RG Evans, BS Gardiner, DW Smith… - American Journal of …, 2008 - journals.physiology.org
The kidney is faced with unique challenges for oxygen regulation, both because its function
requires that perfusion greatly exceeds that required to meet metabolic demand and …

Haemodynamic influences on kidney oxygenation: clinical implications of integrative physiology
Renal blood flow, local tissue perfusion and blood oxygen content are the major
determinants of oxygen delivery to kidney tissue. Arterial pressure and segmental vascular …

Sepsis‐induced acute kidney injury: a disease of the microcirculation
S Ma, RG Evans, N Iguchi, M Tare… - …, 2019 - Wiley Online Library
AKI is a common complication of sepsis and is significantly associated with mortality. Sepsis

[HTML][HTML] Intrarenal and urinary oxygenation during norepinephrine resuscitation in ovine septic acute kidney injury
YR Lankadeva, J Kosaka, RG Evans, SR Bailey… - Kidney International, 2016 - Elsevier
Norepinephrine is the principal vasopressor used to restore blood pressure in sepsis, but its
effects on intrarenal oxygenation are unknown. To clarify this, we examined renal cortical …

Mechanisms underlying the differential control of blood flow in the renal medulla and cortex
RG Evans, GA Eppel, WP Anderson… - Journal of …, 2004 - journals.lww.com
There is much evidence that the medullary circulation plays a key role in regulating renal
salt and water handling and, accordingly, the long-term level of arterial pressure. It has also …

Arterial spin labelling MRI to measure renal perfusion: a systematic review and statement paper
Renal perfusion provides the driving pressure for glomerular filtration and delivers the
oxygen and nutrients to fuel solute reabsorption. Renal ischaemia is a major mechanism in …
